The legislation allows electric utilities, including Duke Energy Carolinas, to
accelerate the recovery of compliance costs by amortizing them over seven years (2003-2009). However, Duke Energy Carolinas ended its amortization in 2007 as part of its rate case settlement with the NCUC.

See Other Matters section of Managements Discussion and Analysis of Financial Condition and Results of Operations for a
discussion about potential Global Climate Change legislation and the potential impacts such legislation could have on Duke Energy Carolinas operations. Additionally, other potential future environmental laws and regulations could have a
significant impact on Duke Energy Carolinas results of operations, cash flows or financial position. However, if such laws are enacted, Duke Energy Carolinas would seek appropriate regulatory recovery of costs to comply within its regulated
operations.

For more information on environmental matters involving Duke Energy Carolinas, including possible liability and
capital costs, see Notes 4 and 14 to the Consolidated Financial Statements, Regulatory Matters, and Commitments and ContingenciesEnvironmental, respectively.

Except to the extent discussed in Note 4 to the Consolidated Financial Statements, Regulatory Matters, and Note 14 to the
Consolidated Financial Statements, Commitments and Contingencies, compliance with current federal, state and local provisions regulating the discharge of materials into the environment, or otherwise protecting the environment, is
incorporated into the routine cost structure of Duke Energy Carolinas business and is not expected to have a material adverse effect on the competitive position, consolidated results of operations, cash flows or financial position of Duke
Energy Carolinas.

PART I



Item 1A. Risk Factors.

The risk factors discussed herein relate specifically to risks associated with Duke Energy Carolinas.

Duke Energy Carolinas revenues, earnings and results are dependent on state legislation and regulation that affect electric
generation, transmission, distribution and related activities, which may limit Duke Energy Carolinas ability to recover costs.

Duke Energy Carolinas is regulated on a cost-of-service/rate-of-return basis subject to the statutes and regulatory commission rules and procedures of North Carolina and South Carolina. If Duke Energy
Carolinas earnings exceed the returns established by the state regulatory commissions, Duke Energy Carolinas retail electric rates may be subject to review and possible reduction by the commissions, which may decrease Duke Energy
Carolinas future earnings. Additionally, if regulatory bodies do not allow recovery of costs incurred in providing service on a timely basis, Duke Energy Carolinas future earnings could be negatively impacted.

Duke Energy Carolinas may incur substantial costs and liabilities due to Duke Energy Carolinas ownership and operation of
nuclear generating facilities.

Duke Energy Carolinas ownership interest in and operation of three nuclear
stations subject Duke Energy Carolinas to various risks including, among other things: the potential harmful effects on the environment and human health resulting from the operation of nuclear facilities and the storage, handling and disposal of
radioactive materials; limitations on the amounts and types of insurance commercially available to cover losses that might arise in connection with nuclear operations; and uncertainties with respect to the technological and financial aspects of
decommissioning nuclear plants at the end of their licensed lives.

Duke Energy Carolinas ownership and operation of
nuclear generation facilities requires Duke Energy Carolinas to meet licensing and safety-related requirements imposed by the Nuclear Regulatory Commission (NRC). In the event of non-compliance, the NRC may increase regulatory oversight, impose
fines, and/or shut down a unit, depending upon its assessment of the severity of the situation. Revised security and safety requirements promulgated by the NRC, which could be prompted by, among other things, events within or outside of Duke Energy
Carolinas control, such as a serious nuclear incident at a facility owned by a third-party, could necessitate substantial capital and other expenditures at Duke Energy Carolinas nuclear plants, as well as assessments against Duke Energy
Carolinas to cover third-party losses. In addition, if a serious nuclear incident were to occur, it could have a material adverse effect on Duke Energy Carolinas results of operations and financial condition.

Duke Energy Carolinas ownership and operation of nuclear generation facilities also requires Duke Energy Carolinas to maintain funded
trusts that are intended to pay for the decommissioning costs of Duke Energy Carolinas nuclear power plants. Poor investment performance of these decommissioning trusts holdings and other factors impacting decommissioning costs could
unfavorably impact Duke Energy Carolinas liquidity and results of operations as Duke Energy Carolinas could be required to significantly increase its cash contributions to the decommissioning trusts.

Duke Energy Carolinas plans for future expansion and modernization of its generation fleet subject it to risk of failure to
adequately execute and manage its significant construction plans, as well as the risk of recovering all such costs or of recovering costs in an untimely manner, which could materially impact Duke Energy Carolinas results of operations, cash
flows or financial position.

The completion of Duke Energy Carolinas anticipated capital investment projects in
existing and new generation facilities is subject to many construction and development risks, including risks related to financing, obtaining and complying with terms of permits, meeting construction budgets and schedules, and satisfying operating
and environmental performance standards. Moreover, Duke Energy Carolinas ability to recover all of these costs and recovering costs in a timely manner could materially impact Duke Energy Carolinas financial position, consolidated results
of operations, or cash flows.

Duke Energy Carolinas must meet credit quality standards and there is no assurance that
it will maintain investment grade credit ratings. If Duke Energy Carolinas is unable to maintain an investment grade credit rating, Duke Energy Carolinas would be required under credit agreements to provide collateral in the form of letters of
credit or cash, which may materially adversely affect Duke Energy Carolinas liquidity.

Duke Energy
Carolinas senior unsecured long-term debt is rated investment grade by various rating agencies. Duke Energy Carolinas cannot be sure that the senior unsecured long-term debt of Duke Energy Carolinas will be rated investment grade in the
future.



If the rating agencies were to rate Duke
Energy Carolinas below investment grade, Duke Energy Carolinas borrowing costs would increase, perhaps significantly. In addition, Duke Energy Carolinas would likely be required to pay a higher interest rate in future financings, and its
potential pool of investors and funding sources would likely decrease. Any downgrade or other event negatively affecting the credit ratings of Duke Energy Carolinas could also increase Duke Energys need to provide liquidity in the form of
capital contributions or loans, thus reducing the liquidity and borrowing availability of the consolidated group.

A downgrade
below investment grade could also require Duke Energy Carolinas to post additional collateral in the form of letters of credit or cash under various credit agreements and trigger termination clauses in some interest rate and derivative agreements,
which would require cash payments. All of these events would likely reduce Duke Energy Carolinas liquidity and profitability and could have a material adverse effect on Duke Energy Carolinas financial position, results of operations, or
cash flows.

Duke Energy Carolinas relies on access to short-term intercompany borrowings and longer-term capital
markets to finance Duke Energy Carolinas capital requirements and support Duke Energy Carolinas liquidity needs, and Duke Energy Carolinas access to those markets can be adversely affected by a number of conditions, many of which
are beyond Duke Energy Carolinas control.

Duke Energy Carolinas business is financed to a large degree
through debt and the maturity and repayment profile of debt used to finance investments often does not correlate to cash flows from Duke Energy Carolinas assets. Accordingly, Duke Energy Carolinas relies on access to longer-term capital
markets as a source of liquidity for capital requirements not satisfied by the cash flow from Duke Energy Carolinas operations or short-term borrowings via Duke Energys money pool arrangement and to fund investments originally financed
through debt instruments with disparate maturities. If Duke Energy Carolinas is not able to access capital at competitive rates or Duke Energy Carolinas cannot obtain short-term borrowings via the money pool arrangement, Duke Energy Carolinas
ability to finance its operations and implement its strategy will be adversely affected.

Market disruptions may increase Duke
Energy Carolinas cost of borrowing or adversely affect Duke Energy Carolinas ability to access one or more financial markets. Such disruptions could include: economic downturns; the bankruptcy of an unrelated energy company; general
capital market conditions; market prices for electricity; terrorist attacks or threatened attacks on Duke Energy Carolinas facilities or unrelated energy companies; or the overall health of the energy industry.

Duke Energy Carolinas parent, Duke Energy, maintains revolving credit facilities to provide back-up for commercial paper programs and
for letters of credit at various entities. Duke Energy Carolinas has borrowing capacity under Duke Energys revolving credit facilities. These facilities typically include financial covenants which limit the amount of debt that can be
outstanding as a percentage of the total capital for the specific entity. Failure to maintain these covenants at either Duke Energy or Duke Energy Carolinas could preclude Duke Energy Carolinas from issuing letters of credit or borrowing under the
revolving credit facility. Additionally, there are no assurances that commitments made by lenders under Duke Energy Carolinas credit facilities will be available as a source of funding due to on-going uncertainties in the financial services
industry.

PART I



Duke Energy Carolinas is exposed to credit risk of customers and counterparties
with whom Duke Energy Carolinas does business.

Adverse economic conditions affecting, or financial difficulties of,
customers and counterparties with whom Duke Energy Carolinas does business could impair the ability of these customers and counterparties to pay for Duke Energy Carolinas services or fulfill their contractual obligations, including loss
recovery payments under insurance contracts, or cause them to delay such payments or obligations. Duke Energy Carolinas depends on these customers and counterparties to remit payments on a timely basis. Any delay or default in payment could
adversely affect Duke Energy Carolinas financial position, results of operations or cash flows.

Poor investment
performance of Duke Energys pension plan holdings and other factors impacting pension plan costs could unfavorably impact Duke Energy Carolinas liquidity and results of operations.

Duke Energy Carolinas participates in employee benefit plans sponsored by its parent, Duke Energy. Duke Energy Carolinas is allocated its
proportionate share of the cost of these plans by Duke Energy. Duke Energys costs of providing non-contributory defined benefit pension plans are dependent upon a number of factors, such as the rates of return on plan assets, discount rates,
the level of interest rates used to measure the required minimum funding levels of the plans, future government regulation and required or voluntary contributions made to the plans. At December 31, 2009, Duke Energy has certain qualified U.S.
pension plans with obligations which exceeded the value of plan assets. Without sustained growth in the pension investments over time to increase the value of Duke Energys plan assets and depending upon the other factors that could
significantly impact Duke Energy Carolinas allocated costs, as discussed above, Duke Energy could be required to fund its plans with significant amounts of cash. Duke Energy Carolinas proportionate share of such cash funding obligations
could have a material impact on Duke Energy Carolinas financial position, results of operations or cash flows.

Duke Energy Carolinas is subject to numerous environmental laws and regulations that require significant capital expenditures, can increase Duke Energy Carolinas cost of operations, and which may impact or limit Duke Energy
Carolinas business plans, or expose Duke Energy Carolinas to environmental liabilities.

Duke Energy Carolinas is subject to numerous environmental laws and regulations affecting many aspects of Duke Energy Carolinas present and future operations, including air emissions (such as reducing NOx, SO2and mercury emissions in the U.S., or potential future control of greenhouse-gas emissions), water quality, wastewater
discharges, solid waste and hazardous waste. These laws and regulations can result in increased capital, operating, and other costs. These laws and regulations generally require Duke Energy Carolinas to obtain and comply with a wide variety of
environmental licenses, permits, inspections and other approvals. Compliance with environmental laws and regulations can require significant expenditures, including expenditures for clean-up costs and damages arising out of contaminated properties,
and failure to comply with environmental regulations may result in the imposition of fines, penalties and injunctive measures affecting operating assets. The steps Duke Energy Carolinas could be required to take to ensure that its facilities are in
compliance could be prohibitively expensive. As a result, Duke Energy Carolinas may be required to shut down or alter the operation of its facilities, which may cause Duke Energy Carolinas to incur losses. Further, Duke Energy Carolinas
regulatory rate structure and Duke Energy Carolinas contracts with clients may not necessarily allow Duke Energy Carolinas to recover capital costs Duke Energy Carolinas incurs to comply with new environmental regulations. Also, Duke Energy
Carolinas may not be able to obtain or maintain from time to time all required environmental regulatory approvals for Duke Energy Carolinas operating assets or development projects. If there is a delay in obtaining any required environmental
regulatory approvals, if Duke Energy Carolinas fails to obtain and comply with them or if environmental laws or regulations change and become more stringent, then the operation of Duke Energy Carolinas facilities or the development of new
facilities could be prevented, delayed or become subject to additional costs. Although it is not expected that the costs of complying with current environmental regulations will have a material adverse effect on Duke Energy Carolinas financial
position, results of operations or cash flows, no assurance can be made that the costs of complying with environmental regulations in the future will not have such an effect.

There is growing consensus that some form of regulation will be forthcoming at the federal level with respect to
greenhouse gas emissions (including carbon dioxide (CO2)) and
such regulation could result in the creation of substantial additional costs in the form of taxes or emission allowances.

The
EPA also has plans to propose new federal regulations governing the management of coal combustions by-products, including fly ash. These regulations may require Duke Energy Carolinas to make additional capital expenditures and increase Duke Energy
Carolinas operating and maintenance costs.

Additionally, potential other new environmental regulations, including the use of
coal from mountain removal and water discharge, could require Duke Energy Carolinas to make additional capital expenditures and increase costs of fuel.



In addition, Duke Energy Carolinas is generally responsible for on-site liabilities, and in some cases, off-site liabilities, associated
with the environmental condition of Duke Energy Carolinas power generation facilities which Duke Energy Carolinas has acquired or developed, regardless of when the liabilities arose and whether they are known or unknown. In connection with
some acquisitions and sales of assets, Duke Energy Carolinas may obtain, or be required to provide, indemnification against some environmental liabilities. If Duke Energy Carolinas incurs a material liability, or the other party to a transaction
fails to meet its indemnification obligations to Duke Energy Carolinas, it could suffer material losses.

Deregulation
or restructuring in the electric industry may result in increased competition and unrecovered costs that could adversely affect Duke Energy Carolinas financial position, results of operations or cash flows and Duke Energy Carolinas
business.

Increased competition resulting from deregulation or restructuring efforts, including from the Energy
Policy Act of 2005, could have a significant adverse financial impact on Duke Energy Carolinas and consequently on its results of operations, financial position, or cash flows. Increased competition could also result in increased pressure to lower
costs, including the cost of electricity. Duke Energy Carolinas cannot predict the extent and timing of entry by additional competitors into the electric markets, nor can Duke Energy Carolinas predict the impact of these changes on its financial
position, results of operations or cash flows.

Duke Energy Carolinas is involved in numerous legal proceedings, the
outcome of which are uncertain, and resolution adverse to Duke Energy Carolinas could negatively affect Duke Energy Carolinas financial condition, results of operations or cash flows.

Duke Energy Carolinas is subject to numerous legal proceedings, including claims for bodily damages alleged to have arisen prior to 1985
from the exposure to or use of asbestos at electric generation plants of Duke Energy Carolinas. Litigation is subject to many uncertainties and Duke Energy Carolinas cannot predict the outcome of individual matters with assurance. It is reasonably
possible that the final resolution of some of the matters in which Duke Energy Carolinas is involved could require Duke Energy Carolinas to make additional expenditures, in excess of established reserves, over an extended period of time and in a
range of amounts that could have a material effect on Duke Energy Carolinas financial position, results of operations or cash flows. Similarly, it is reasonably possible that the terms of resolution could require Duke Energy Carolinas to
change its business practices and procedures, which could also have a material effect on Duke Energy Carolinas financial position, results of operations or cash flows.

Duke Energy Carolinas results of operations may be negatively affected by overall market, economic and other conditions that are
beyond Duke Energy Carolinas control.

Sustained downturns or sluggishness in the economy generally affect the
markets in which Duke Energy Carolinas operates and negatively influence Duke Energy Carolinas energy operations. Declines in demand for electricity as a result of economic downturns in Duke Energy Carolinas service territories will
reduce overall sales and lessen Duke Energy Carolinas cash flows, especially as Duke Energy Carolinas industrial customers reduce production and, therefore, consumption of electricity. Although Duke Energy Carolinas business is
subject to regulated allowable rates of return and recovery of fuel costs under a fuel adjustment clause, overall declines in electricity sold as a result of economic downturn or recession could reduce revenues and cash flows, thus diminishing
results of operations.

Duke Energy Carolinas also sells electricity into the spot market or other competitive power markets
on a contractual basis. With respect to such transactions, its revenues and results of operations are likely to depend, in large part, upon prevailing market prices in Duke Energy Carolinas regional markets

PART I



and other competitive markets. These market prices may fluctuate substantially over relatively short periods of time and could reduce Duke Energy Carolinas revenues and margins and thereby
diminish Duke Energy Carolinas results of operations.

Factors that could impact sales volumes, generation of
electricity and market prices at which Duke Energy Carolinas is able to sell electricity are as follows:



| |  |  | weather conditions, including abnormally mild winter or summer weather that cause lower energy usage for heating or cooling purposes, respectively, and
periods of low rainfall that decrease Duke Energy Carolinas ability to operate its facilities in an economical manner;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | supply of and demand for energy commodities;
| | - |  | --------------------------------------------



| |  |  | availability of competitively priced alternative energy sources, which are preferred by some customers over electricity produced from coal, nuclear or
gas plants, and of energy-efficient equipment which reduces energy demand;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | ability to procure satisfactory levels of inventory, such as coal and uranium; and
| | - |  | ----------------------------------------------------------------------------------



| |  |  | capacity and transmission service into, or out of, Duke Energy Carolinas markets.
| | - |  | ----------------------------------------------------------------------------------

These factors have led to industry-wide downturns that have resulted in the slowing down or stopping of construction of new power plants and
announcements by other energy suppliers of plans to sell non-strategic assets, subject to regulatory constraints, in order to boost liquidity or strengthen balance sheets. Proposed sales by other energy suppliers could increase the supply of the
types of assets that Duke Energy Carolinas could attempt to sell. In addition, recent FERC actions addressing power market concerns could negatively impact the marketability of Duke Energy Carolinas electric generation assets.

Duke Energy Carolinas operating results may fluctuate on a seasonal and quarterly basis.

Electric power generation is generally a seasonal business. In the markets in which Duke Energy Carolinas operates, demand for power peaks
during the warmer summer months and colder winter months, with market prices also peaking at that time. Further, extreme weather conditions such as heat waves or winter storms could cause these seasonal fluctuations to be more pronounced. As a
result, in the future, the overall operating results of Duke Energy Carolinas businesses may fluctuate substantially on a seasonal and quarterly basis and thus make period comparison less relevant.

Duke Energy Carolinas business is subject to extensive federal regulation that will affect Duke Energy Carolinas
operations and costs.

Duke Energy Carolinas is subject to regulation by FERC and the NRC, and various other federal
agencies. Regulation affects almost every aspect of Duke Energy Carolinas businesses, including, among other things, Duke Energy Carolinas ability to: take fundamental business management actions; determine the terms and rates of Duke
Energy Carolinas transmission business services; make acquisitions; issue equity or debt securities; engage in transactions between Duke Energy Carolinas utilities and other subsidiaries and affiliates; and the ability to pay
dividends to Duke Energy. Changes to these regulations are ongoing, and Duke Energy Carolinas cannot predict the future course of changes in this regulatory environment or the ultimate effect that this changing regulatory environment will have on
Duke Energy Carolinas business. However, changes in regulation can cause delays in or affect business planning and transactions and can substantially increase Duke Energy Carolinas costs.

New laws or regulations could have a negative impact on Duke Energy Carolinas financial position, results of operations or cash
flows.

Changes in laws and regulations affecting Duke Energy Carolinas, including new accounting standards could
change the way Duke Energy Carolinas is required to record revenues, expenses, assets and liabilities. These types of regulations could have a negative impact on Duke Energy Carolinas financial position, cash flows or results of operations or
access to capital.

Potential terrorist activities or military or other actions could adversely affect Duke Energy
Carolinas business.

The continued threat of terrorism and the impact of retaliatory military and other action
by the United States and its allies may lead to increased political, economic and financial market instability and volatility in prices for natural gas and oil which may materially adversely affect Duke Energy Carolinas in ways it cannot predict at
this time. In addition, future acts of terrorism and any possible reprisals as a consequence of action by the United States and its allies could be directed against companies operating in the United States. Infrastructure and generation facilities
such as Duke Energy Carolinas nuclear plants could be potential targets of terrorist activities. The potential for terrorism has subjected Duke Energy Carolinas operations to increased risks and could have a material adverse effect on
Duke Energy Carolinas business. In particular, Duke Energy Carolinas may experience increased capital and operating costs to implement increased security for its plants, including its nuclear power plants under the NRCs design basis
threat requirements, such as additional physical plant security, additional security personnel or additional capability following a terrorist incident.

The insurance industry has also been disrupted by these events. As a result, the availability of insurance covering risks that Duke Energy Carolinas and its competitors typically insure against may
decrease. In addition, the insurance Duke Energy Carolinas is able to obtain may have higher deductibles, higher premiums and more restrictive policy terms.

Additional risks and uncertainties not currently known to Duke Energy Carolinas or that Duke Energy Carolinas currently deems to be immaterial also may materially adversely affect Duke Energy
Carolinas financial condition, results of operations or cash flows.

Operating Revenues.The decrease was driven primarily by:



| |  |  | A $248 million decrease in fuel revenues driven primarily by decreased demand from both retail and near-term wholesale customers. Fuel revenues
represent sales to retail and wholesale customers,
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A $62 million decrease in rates charged to retail customers primarily due to the expiration of the one-time increment rider related to merger savings
that was included in North Carolina retail rates in 2008,
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A $52 million decrease due to lower weather adjusted sales volumes to retail customers reflecting both the overall decline in economic conditions,
which are primarily impacting the industrial sector, and the general decline in the textile industry in the Carolinas, and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A $35 million decrease in wholesale power revenues, net of sharing, primarily due to decreased sales volumes and lower prices on near-term sales as a
result of weak market conditions, partially offset by higher prices and increased sales volumes under certain long-term contracts.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Operating Expenses.The decrease was driven primarily by:



| |  |  | A $247 million decrease in fuel expense (including purchased power) primarily due to a lower volume of coal and natural gas used in electric generation
and decreased purchased power expense, driven by lower demand from both retail and wholesale customers, and lower natural gas prices; partially offset by higher coal prices,
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A $112 million decrease in operating and maintenance expenses primarily due to lower scheduled outage and maintenance costs at nuclear and fossil
generating plants, lower management fees from a consolidated affiliate of Duke Energy Corporation (Duke Energy), lower power delivery maintenance, and decreased capacity costs due to the expiration of certain drought mitigation contracts in 2008,
partially offset by increased employee benefit costs, and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A $38 million decrease in depreciation and amortization primarily due to lower depreciation rates, partially offset by increases in depreciation due to
additional capital spending.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Partially offsetting these decreases was:



| |  |  | An $18 million increase in property and other taxes, due primarily to increases in capital expenditures.
| | - |  | --------------------------------------------------------------------------------------------------------

Gains on Sales of Other Assets and Other, net.The increase is primarily attributable to gains on sales of nitrogen oxide
(NOx) emission allowances in 2009.

Other Income and Expenses, net.The increase is primarily due
to the equity component of Allowance for Funds Used During Construction (AFUDC) earned from additional capital spending for ongoing construction projects, partially offset by decreased interest income on short-term investments.

Income Tax Expense.Income tax expense increased due to higher pre-tax income.

Matters Impacting Future Results

Duke Energy Carolinas continues to increase the overall number of retail customers served, maintain low costs and deliver high-quality
customer service; however, sales to all retail customer classes were negatively impacted by the economic downturn in 2009, particularly sales to the industrial sector. These trends are expected to continue for some period into 2010, and perhaps
beyond, until the economy begins to recover. The general decline in the textile industry in the Carolinas, exacerbated by the struggling economy, is also expected to continue in 2010, fueled by the expiration of certain import limitations related to
foreign textile products.

In December 2009, the North Carolina Utilities Commission (NCUC) approved Duke Energy
Carolinas proposed settlement in a request to raise base rates. The settlement agreement includes a base rate increase of approximately $315 million that will be reflected in 2010 earnings, although the full cash impact to customers will be
phased in over two years. In January 2010, the Public Service Commission of South Carolina (PSCSC) approved Duke Energy Carolinas proposed settlement agreement in a request to raise base rates in that jurisdiction. The settlement agreement
includes a base rate increase of approximately $74 million that will be reflected in 2010 earnings, although the full cash impact to customers will be phased in over three years.

In January 2010, Duke Energy announced plans to offer a voluntary severance plan to approximately 8,750 eligible employees. As this is a
voluntary plan, all severance benefits offered under this plan are considered special termination benefits under GAAP. Special termination benefits are measured upon employee acceptance and recorded immediately absent a significant retention period.
If a significant retention period exists, the cost of the special termination benefits are recorded ratably over the remaining service periods of the affected employees. The window for employees to request to voluntarily end their employment under
this plan opened on February 3, 2010 and closed on February 24, 2010 for 8,400 eligible employees, which includes approximately 4,033 Duke Energy Carolinas employees. Additionally Duke Energy Carolinas will be allocated its proportionate
share of benefits costs for employees of Duke Energys shared services affiliate that provides support to Duke Energy Carolinas. Duke Energy Carolinas currently estimates severance payments associated with this voluntary plan, including
allocated costs discussed above of approximately $84 million. However, until management of Duke Energy approves the requests, it reserves the right to reject any request to volunteer based on business needs and/or excessive participation.

Other Matters

Duke Energy Carolinas fixed charges coverage ratio, as calculated using Securities and Exchange Commission guidelines, was 3.5 times for both 2009 and 2008 and 4.0 times for 2007.

Capital Expenditures.Duke Energy Carolinas capital expenditures forecast of approximately $7 billion for the three-year period
from 2010 to 2012 principally relates to expansion plans, required maintenance and nuclear fuel. Current estimates are that Duke Energy Carolinas generation capacity in North Carolina and South Carolina will need to increase by approximately
5,400 megawatts (MW) over the next ten years. Duke Energy Carolinas plans to meet this additional demand through a diverse portfolio consisting of new generating capacity, including generation from renewable power sources, advanced nuclear power,
advanced clean-coal and high-efficiency natural gas electric generating plants and energy efficiency. Duke Energy Carolinas is committed to adding baseload capacity at a reasonable price while modernizing the current generation facilities by
replacing older, less efficient plants with cleaner, more efficient plants. Construction of an 825 MW state of the art coal generation unit is ongoing at Duke Energy Carolinas existing Cliffside facility in North Carolina (Cliffside Unit 6).
At December 31, 2009, the construction of Cliffside Unit 6 is approximately 55% complete and is currently anticipated to be in operation in 2012. Additionally, Duke Energy Carolinas has begun construction on a 620 MW combined cycle natural
gas-fired generating facility at each of its Buck and Dan River Steam Stations that are anticipated to be in operation in 2011 and 2012, respectively. Once in service, Duke Energy Carolinas will be able to retire older, less efficient plants. Duke
Energy Carolinas continues to evaluate the construction of a new nuclear power plant in Cherokee County, South Carolina.

Global Climate Change. Although there is still much to learn about the causes and long-term effects of climate change, many, including Duke Energy Carolinas, advocate taking steps now to begin reducing greenhouse gas (GHG) emissions
with the long-term aim of stabilizing the atmospheric concentration of GHGs at a level that avoids any potentially worst-case effects of climate change.

The U.S. Environmental Protection Agency (EPA) publishes an inventory of man-made U.S. GHG emissions annually. Carbon
dioxide (CO2), a byproduct of fossil fuel combustion,
currently accounts for about 85% of total U.S. GHG emissions. Duke Energy Carolinas GHG emissions consist primarily of CO2and most come from its fleet of coal fired power plants in the U.S. In 2009, Duke Energy Carolinas power plants
emitted approximately 36 million tons of CO2. Duke
Energy Carolinas future CO2emissions will be
influenced by variables including new regulations, economic conditions that affect electricity demand, and Duke Energy Carolinas decisions regarding generation technologies deployed to meet customer electricity needs.



Congress has not yet passed legislation mandating control or
reduction of GHGs. On June 26, 2009, the U.S. House of Representatives passed H.R. 2454the American Clean Energy and Security Act of 2009 (ACES). This legislation includes a GHG cap-and-trade program that covers approximately 85% of the
GHG emissions in the U.S. economy, including emissions from the electric utility sector. The legislation also includes a combined efficiency and renewable electricity standard that applies to the electric utility sector. The standard establishes
minimum requirements for the amount of renewable energy electric utilities must provide to end-use customers on an annual basis. It allows companies to comply by providing renewable energy, buying renewable energy credits from other companies or the
government, or by reducing customer electricity demand through the deployment of energy efficiency programs.

On
November 5, 2009, the U.S. Senate Environment and Public Works Committee passed and sent to the U.S. Senate floor S. 1733the Clean Energy Jobs and American Power Act of 2009 (S. 1733). The legislation included an economy-wide
cap-and-trade program similar to the one contained in ACES. The U.S. Senate Energy and Natural Resources Committee had previously passed legislation containing new requirements for energy efficiency and for a renewable electricity standard. No
further U.S. Senate action has been taken on either bill since passage out of their respective committees.

The debates that
took place in the U.S. Senate in 2008 and 2009 make it clear that there are wide-ranging views among Senators regarding what constitutes acceptable climate change legislation. These divergent views, the state of the economy, the current structure of
the Senate necessitating 60 votes to move legislation and the political pressures as the 2010 mid-term election approaches, make passage of federal climate change legislation in the Senate in 2010 highly uncertain. If the Senate were to pass some
type of climate change legislation in 2010, the Senate legislation would need to be reconciled with ACES. This adds another layer of uncertainty to the prospects for enactment of climate change legislation in 2010.

On December 7, 2009, the EPA finalized an Endangerment Finding for greenhouse gases under the Clean Air Act (CAA). The Endangerment
Finding does not impose any regulatory requirements on industry, but is a necessary prerequisite for the EPA to be able to finalize its proposed GHG emission standard for new motor vehicles. It is expected that the EPA will finalize its New Motor
Vehicle Rule by the end of March 2010. Implementation of the New Motor Vehicle Rule may trigger permitting requirements and potentially GHG emission control requirements for new and existing major stationary sources of GHG emissions
which would include all of Duke Energy Carolinas fossil fuel facilities. The EPA has stated that permitting requirements for GHGs will not apply to stationary sources in 2010.

##### Table of Contents

PART II



The EPA has also proposed the Tailoring Rule, which could be finalized by the end of
March 2010. This rule is intended to provide relief from the EPAs GHG regulations for certain types of stationary sources, but not electric generating facilities. There is, at present, considerable uncertainty over the timing and the specific
requirements that would apply to any stationary source that might potentially be subject to GHG permitting and emission reduction requirements as a result of the EPAs rules. Although Duke Energy Carolinas does not anticipate taking actions
that would trigger the GHG permitting requirements or GHG emission reduction requirements at any of its existing generating facilities, if it were to do so, the current uncertainty surrounding the implementation of the rules and the requirements
that might apply prevent management from being able to determine at this time whether the EPA rules will have a material impact on Duke Energy Carolinas future results of operations. Numerous groups have already filed petitions with the D.C.
Circuit Court of Appeals for review of the EPAs Endangerment Finding. It is likely that the EPAs upcoming New Motor Vehicle and Tailoring rules will also be challenged in court once they are finalized. The current and expected legal
challenges create additional uncertainty with respect to the EPA rules and what regulatory requirements, if any, will result from the rules.

Duke Energy Carolinas supports the enactment of workable federal GHG legislation. Duke Energy Carolinas prefers federal legislation over any EPA regulation of GHG emissions under the current CAA and
believes that any legislation must include provisions that block the EPA from doing so and provide that the legislative program is the sole remedy for a sources GHG emissions. To permit the economy to adjust rationally to the policy,
legislation should establish a long-term program that first slows the growth of emissions, stops them and then transitions to a gradually declining emissions cap as new lower-and zero-emitting technologies are developed and become available for
wide-scale deployment at a reasonable cost. Federal legislation should also include effective cost-containment measures to protect the U.S. economy from harmful consequences if compliance costs are excessive.

Duke Energy Carolinas is unable to determine the potential cost of complying with unspecified and unknowable future GHG legislation or any
indirect costs that might result, however, such costs could be significant. Duke Energy Carolinas cost of complying with any legislatively-mandated federal GHG emissions regulations will depend upon the design details of the program, and upon
the future levels of Duke Energy Carolinas GHG emissions that might be regulated under the program. If potential future federal GHG legislation mandates a cap-and-trade approach, for example, the design elements of such a program that will
have the greatest influence on Duke Energy Carolinas compliance costs include (i) the level of the emissions cap over time, (ii) the GHG emission sources covered under the cap, (iii) the number of allowances that Duke Energy
Carolinas might be allocated at no cost on a year-to-year basis, (iv) the type and effectiveness of any cost containment measures that may be included in the program, (v) the role of emission offsets in the program, (vi) the
availability and cost of technologies that will be available for Duke Energy Carolinas to deploy to lower its emissions over time, and (vii) the price of allowances and emission offsets. Although Duke Energy Carolinas believes it is likely that
Congress will adopt mandatory GHG emission reduction legislation at some point, the timing and design details of any such legislation are highly uncertain at this time.

Assuming that a federal GHG cap-and-trade program is eventually enacted, Duke Energy Carolinas compliance obligation under such a program would generally be determined by the difference between the
level of its covered emissions in a given year and the number of no-cost allowances it receives for that year. This difference would represent the emission reductions that Duke Energy Carolinas would need to achieve to comply, the number of
allowances and/or offsets Duke Energy Carolinas would need to purchase to comply, or a combination of the two. The cost of achieving the emission reductions and/or the cost of purchasing the needed allowances and/or emission offsets would represent
Duke Energy Carolinas compliance costs. This is why the more no-cost allowances Duke Energy Carolinas receives, the lower its compliance obligation will be, and the lower its compliance cost will be. This is also why actions Duke Energy
Carolinas is taking today to reduce its GHG emissions over time will lower its exposure to any future GHG regulation. Under any future scenario involving mandatory GHG limitations, Duke Energy Carolinas would plan to seek to recover its compliance
costs through appropriate regulatory mechanisms in the jurisdictions in which it operates.

Although a
near-term compliance strategy under a GHG cap-and-trade program might be focused primarily on the purchase of allowances and/or offsets due to the lack of available emission reduction technologies and/or the time it would take to deploy technologies
once they become available, it is likely that over time there would be more focus placed on deploying technology to achieve large-scale reductions in emissions. This strategy could involve replacing some existing coal-fired generation with new
lower-and zero-emitting generation technologies. Although there is uncertainty about what new technologies might be developed, when they might be deployed, and what their costs will be, Duke Energy Carolinas currently is focused on advanced nuclear
generation for generating electricity with lower or no CO2emissions. Duke Energy is also making a significant commitment to increased customer energy efficiency and promoting enhanced use of renewable energy for meeting customers electricity needs. Duke Energy Carolinas actions are designed to
build a sustainable business that allows our customers and our shareholders to prosper in what is expected to be a carbon-constrained environment.

In December 2007, Duke Energy Carolinas began the regulatory process to construct a new nuclear power plant (William States Lee III Nuclear Station) in South Carolina, petitioning the NRC for a combined
construction and operating license (COL). If constructed, this facility would produce virtually no GHGs.

The state legislature of North Carolina has passed laws that require Duke Energy Carolinas to meet increasing percentages of its customers electricity needs with renewable energy and customer energy efficiency. The requirement reaches
12.5% in 2021. Duke Energy Carolinas will be meeting these requirements through a variety of actions and each is expected to assist Duke Energy Carolinas overall effort to reduce its CO2emissions. Versions of an energy efficiency and renewable electricity standard have been passed by the U.S.
House of Representatives as part of ACES and by the U.S. Senate Energy and Natural Resources Committee in S. 1462. Given the current challenges associated with passing comprehensive federal climate change legislation, Congress could instead attempt
to pass energy legislation in 2010 that includes a federal energy efficiency and renewable electricity standard  provisions both the full U.S. House of Representatives and a U.S. Senate committee have approved, albeit at different levels. If
this were to occur, the requirements would help Duke Energy Carolinas comply with whatever federal requirements Congress might enact.

In addition to relying on new technologies to reduce its CO2emissions, Duke Energy Carolinas has filed for regulatory approval in North Carolina and South Carolina for a first-of-its-kind innovative approach in the utility industry to help meet customer
electricity needs with new and creative ways to increase energy efficiency, thereby reducing demand instead of relying almost exclusively on new power plants to generate electricity. Duke Energy Carolinas has received regulatory approval from North
Carolina and South Carolina and is in the process of rolling programs out in these states.

Duke Energy recognizes that
certain groups associate frequent and severe extreme weather events with climate change and the associated damage to the electric distribution system and the possibility that these weather events could have a material impact on future results of
operations should these events occur. However, the uncertain nature of potential changes in extreme weather events (such as increased frequency, duration, and severity), the long period of time over which any changes might take place, and the
inability to predict these accurately, make estimating any potential future financial risk to Duke Energy Carolinas operations that may be caused by the physical risks of climate change impossible. Currently, Duke Energy Carolinas plans and
prepares for extreme weather events that it experiences from time to time, such as ice storms, tornados, severe thunderstorms, high winds and droughts. Duke Energy Carolinas past experiences preparing for and responding to the impacts of these
types of weather-related events would reasonably be expected to help management plan and prepare for future climate change-related severe weather events to reduce, but not eliminate, the operational, economic and financial impacts of such events.
Duke Energy Carolinas also routinely takes steps to reduce the potential impact of severe

weather events on its electric distribution systems. Duke Energy Carolinas does not currently operate in coastal areas and therefore is not exposed to the effects of potential sea level rise.
Duke Energy Carolinas electric generating facilities are designed to withstand extreme weather events without damage. Duke Energy Carolinas maintains an inventory of coal and oil on site to mitigate the effects of any potential short-term
disruption in its fuel supply so it can continue to provide its customers with an uninterrupted supply of electricity.

Contingencies.

Quantitative and Qualitative Disclosures About Market Risk

Risk Management Policies

Duke Energy Carolinas is exposed to market risks associated with commodity prices, credit exposure, interest rates and equity prices. Management has established comprehensive risk management policies to monitor and manage these market
risks. The Chief Risk Officer of Duke Energy Carolinas parent entity, Duke Energy, is responsible for the overall governance of managing credit risk and commodity price risk, including monitoring exposure limits.

Commodity Price Risk

Duke
Energy Carolinas has limited exposure to market price changes in fuel incurred for its retail customers due to the cost tracking and recovery mechanisms in its retail jurisdictions. Duke Energy Carolinas does have exposure to the impact of market
fluctuations in the prices of electricity, fuel and emissions allowances with its bulk power marketing (BPM) sales. Price risk represents the potential risk of loss from adverse changes in the market price of electricity or other energy commodities.
Duke Energy Carolinas employs established policies and procedures to manage its risks associated with these market fluctuations using various commodity derivatives, such as forwards and swaps. For further information see Note 8 to the Consolidated
Financial Statements, Risk Management, Derivative Instruments and Hedging Activities.

Validation of a
contracts fair value is performed by an internal group separate from Duke Energy Carolinas deal origination areas. While Duke Energy Carolinas uses common industry practices to develop its valuation techniques, changes in Duke Energy
Carolinas pricing methodologies or the underlying assumptions could result in significantly different fair values and income recognition.

Generation Portfolio Risks. For 2010, Duke Energy Carolinas is primarily exposed to market price fluctuations of wholesale power prices through its BPM activities. The generation portfolio not
utilized to serve native load or committed load is subject to commodity price fluctuations, although the impact on the Consolidated Statements of Operations reported earnings is partially offset by mechanisms in the regulated jurisdictions that
result in the sharing of net profits from these activities with retail customers. Based on a sensitivity analysis as of December 31, 2009 and 2008, it was estimated that a ten percent price change per megawatt hour (MWh) in forward wholesale
power prices would have a corresponding effect on Duke Energy Carolinas pre-tax income of approximately $1 million in 2010 and would have had a $3 million impact in 2009, respectively, excluding the impact of mark-to-market changes on
undesignated hedges relating to periods in excess of one year from the respective date.

Normal Purchases and Normal Sales
(NPNS). Duke Energy Carolinas enters into contracts that qualify for the NPNS exception described in the accounting guidance for derivatives. When a contract meets the criteria to qualify as a NPNS, Duke Energy Carolinas applies such exception.
Income recognition and realization related to NPNS contracts generally coincide with the physical delivery of power. For contracts qualifying for such exception, no recognition of the contracts fair value in the Consolidated Financial
Statements is required until settlement of the contract as long as the transaction remains probable of occurring. NPNS contracts are generally subject to collateral requirements under the same credit risk management guidelines used for other
contracts. Duke Energy Carolinas has applied this scope exception for certain contracts involving the purchase and sale of electricity.

The commodity price sensitivity calculations consider existing hedge positions and estimated production levels, but do not consider other potential effects that might result from such changes in commodity
prices.

Duke Energy Carolinas exposure to commodity price risk is influenced by a number of factors, including contract
size, length, market liquidity, location and unique or specific contract terms.

Credit Risk

Credit risk represents the loss that Duke Energy Carolinas would incur if a counterparty fails to perform under its contractual obligations.



Retail. Credit risk associated with Duke
Energy Carolinas service to residential, commercial and industrial customers is generally limited to outstanding accounts receivable. Duke Energy Carolinas mitigates this credit risk by requiring customers to provide a cash deposit or letter
of credit until a satisfactory payment history is established, at which time the deposit is typically refunded. Charge-offs for the retail customers have historically been insignificant to the operations of Duke Energy Carolinas and are typically
recovered through the retail rates. However, in light of current overall economic conditions, management continues to monitor customer charge-offs and payment patterns to ensure the adequacy of bad debt reserves.

BPM. To reduce credit exposure related to BPM, Duke Energy Carolinas seeks to enter into netting agreements with counterparties that
permit Duke Energy Carolinas to offset receivables and payables with such counterparties. Duke Energy Carolinas attempts to further reduce credit risk with certain counterparties by entering into agreements that enable Duke Energy Carolinas to
obtain collateral or to terminate or reset the terms of transactions after specified time periods or upon the occurrence of credit-related events. Where exposed to credit risk, Duke Energy Carolinas analyzes the counterparties financial
condition prior to entering into an agreement, establishes credit limits and monitors the appropriateness of those limits on an ongoing basis.

Duke Energy Carolinas principal customers for BPM are marketers, local distribution companies and utilities located throughout the Southeastern United States. Duke Energy Carolinas has
concentrations of receivables from the electric utilities sector. These concentrations of customers may affect Duke Energy Carolinas overall credit risk in that risk factors can negatively impact the credit quality of the entire sector. Based
on Duke Energy Carolinas policies for managing credit risk, its exposures and its credit and other reserves, Duke Energy Carolinas does not anticipate a materially adverse effect on its consolidated financial position or results of operations
as a result of non-performance by any counterparty.

Other. Duke Energy Carolinas has a third-party insurance policy to
cover certain losses related to asbestos-related injuries and damages above an aggregate self insured retention of $476 million. Duke Energy Carolinas cumulative payments began to exceed the self insurance retention on its insurance policy
during the second quarter of 2008. Future payments up to the policy limit will be reimbursed by Duke Energy Carolinas third party insurance carrier. The insurance policy limit for potential future insurance recoveries for indemnification and
medical cost claim payments is $1,051 million in excess of the self insured retention. Insurance recoveries of approximately $984 million and $1,032 million related to this policy are classified in the Consolidated Balance Sheets primarily in Other
within Investments and Other Assets and Receivables as of December 31, 2009 and 2008, respectively. Duke Energy Carolinas is not aware of any uncertainties



12

regarding the legal sufficiency of insurance claims. Management believes the insurance recovery asset is probable of recovery as the insurance carrier continues to have a strong financial
strength rating.

Duke Energy Carolinas is also subject to credit risk of its vendors and suppliers in the form of performance
risk on contracts including, but not limited to, outsourcing arrangements, major construction projects and commodity purchases. Duke Energy Carolinas credit exposure to such vendors and suppliers may take the form of increased costs or project
delays in the event of non-performance.

Interest Rate Risk

Duke Energy Carolinas is exposed to risk resulting from changes in interest rates as a result of its issuance of variable and fixed rate
debt. Duke Energy Carolinas manages its interest rate exposure by limiting its variable-rate exposures to a percentage of total capitalization and by monitoring the effects of market changes in interest rates. Duke Energy Carolinas also enters into
financial derivative instruments, including, but not limited to, interest rate swaps and U.S. Treasury lock agreements to manage and mitigate interest rate risk exposure. See Notes 8 and 13 to the Consolidated Financial Statements, Risk
Management, Derivative Instruments and Hedging Activities, and Debt and Credit Facilities, respectively.

Based on a sensitivity analysis as of December 31, 2009, it was estimated that if market interest rates average 1% higher (lower) in 2010 than in 2009, interest expense, net of offsetting impacts in interest income, would decrease
(increase) by approximately $5 million. Comparatively, based on a sensitivity analysis as of December 31, 2008, had interest rates averaged 1% higher (lower) in 2009 than in 2008, it was estimated that interest expense, net of offsetting
impacts in interest income, would have increased (decreased) by approximately $2 million. These amounts were estimated by considering the impact of the hypothetical interest rates on variable-rate securities outstanding, adjusted for interest rate
hedges, short-term and long-term investments, cash and cash equivalents outstanding as of December 31, 2009 and 2008. The decrease in interest rate sensitivity is primarily due to an increase of cash and short-term investments and lower
short-term borrowings. If interest rates changed significantly, management would likely take actions to manage its exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, the
sensitivity analysis assumes no changes in Duke Energys financial structure.

Marketable Securities Price Risk

Nuclear Decommissioning Trust Funds (NDTF).As required by the Nuclear Regulatory Commission (NRC) and the NCUC, Duke Energy Carolinas
maintains trust funds to fund the costs of nuclear decommissioning (see Note 7 to the Consolidated Financial Statements, Asset Retirement Obligations). As of December 31, 2009, these funds were invested primarily in domestic and
international equity securities, debt securities, fixed-income securities, cash and cash equivalents and short-term investments. Per the NRC and the NCUC requirements, these funds may be used only for activities related to nuclear decommissioning.
The investments in equity securities are exposed to price fluctuations in equity markets. Accounting for nuclear decommissioning recognizes that costs are recovered through Duke Energy Carolinas rates; therefore, fluctuations in equity prices
do not affect Duke Energy Carolinas Consolidated Statements of Operations as changes in the fair value of these investments are deferred as regulatory assets or regulatory liabilities pursuant to an Order by the NCUC. Earnings or losses of the
fund will ultimately impact the amount of costs recovered through Duke Energy Carolinas rates.

In 2005, the NCUC and
PSCSC approved a $48 million annual amount for contributions and expense levels for decommissioning. In each of the years ended December 31, 2009, 2008 and 2007, Duke Energy expensed approximately $48 million and contributed cash of
approximately $48 million to the NDTF for decommissioning costs. The balance of the external NDTF, was approximately $1,765 million and $1,436 million as of December 31, 2009 and 2008, respectively.

As the NCUC and the PSCSC require that Duke Energy update its cost estimate for decommissioning its nuclear plants every five years, new
site-specific nuclear decommissioning cost studies were completed in January 2009 that showed total estimated nuclear decommissioning costs, including the cost to decommission plant components not subject to radioactive contamination, of
approximately $3 billion in 2008 dollars. This estimate includes Duke Energys approximate 19% ownership interest in the Catawba Nuclear Station. The other joint owners of Catawba Nuclear Station are responsible for decommissioning costs
related to their ownership interests in the station. Duke Energy filed these site-specific nuclear decommissioning cost studies with the NCUC and the PSCSC in April 2009. In addition to the decommissioning cost studies, a new funding study was
completed and indicates the current annual funding requirement of approximately $48 million is sufficient to cover the estimated decommissioning costs. Both the NCUC and the PSCSC approved the existing $48 million annual funding level for nuclear
decommissioning costs.

Both the NCUC and the PSCSC have allowed Duke Energy to recover estimated decommissioning costs
through retail rates over the expected remaining service periods of Duke Energys nuclear stations. Duke Energy believes that the decommissioning costs being recovered through rates, when coupled with expected fund earnings, will be sufficient
to provide for the cost of future decommissioning.

The following table provides the fair value of investments held in the
NDTF at December 31, 2009:

Pension and Other Post-Retirement Benefit Plans.Duke Energy Carolinas proportionate share of Duke Energys costs of providing non-contributory defined benefit retirement and other post-retirement benefit plans are dependent upon a number of factors, such as the rates of return on
plan assets, discount rate, the rate of increase in health care costs and contributions made to the plans. In 2009, Duke Energy contributed approximately $800 million to its qualified pension plans, of which approximately $158 million was funded by
Duke Energy Carolinas. See Note 15 to the Consolidated Financial Statements, Employee Benefit Plans, for additional information on pension plan assets.

Item 8. Financial Statements and Supplementary Data.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors of Duke Energy Carolinas, LLC

Charlotte, North Carolina

We have audited the accompanying consolidated balance sheets of Duke Energy Carolinas, LLC and subsidiaries (the Company) as of
December 31, 2009 and 2008, and the related consolidated statements of operations, members equity and comprehensive income, and cash flows for each of the three years in the period ended December 31, 2009. Our audits also included
the financial statement schedule listed in the Index at Item 15. These financial statements and financial statement schedule are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial
statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of
the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not
required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Companys internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements
referred to above present fairly, in all material respects, the financial position of Duke Energy Carolinas, LLC and subsidiaries at December 31, 2009 and 2008, and the results of their operations and their cash flows for each of the years in
the three-year period ended December 31, 2009 in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic
consolidated financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

DUKE ENERGY CAROLINAS, LLC

Notes To Consolidated Financial Statements

For the
Years Ended December 31, 2009, 2008 and 2007

1. Summary of Significant Accounting Policies

Nature of Operations and Basis of Consolidation.Duke Energy Carolinas, LLC (Duke Energy Carolinas), a wholly-owned subsidiary of Duke
Energy Corporation (Duke Energy), is an electric utility company with operations in North Carolina and South Carolina. Duke Energy Carolinas operates one reportable business segment, Franchised Electric. For additional information regarding this
business segment, including financial information, see Note 2.

These Consolidated Financial Statements include, after
eliminating intercompany transactions and balances, the accounts of Duke Energy Carolinas. These Consolidated Financial Statements also reflect Duke Energy Carolinas approximate 19 percent undivided interest in the Catawba Nuclear Station. See
Note 3 for discussion regarding Duke Energy Carolinas purchase of an additional ownership interest in the Catawba Nuclear Station during 2008.

Use of Estimates. To conform to generally accepted accounting principles (GAAP) in the United States, management makes estimates and assumptions that affect the amounts reported in the Consolidated
Financial Statements and Notes. Although these estimates are based on managements best available information at the time, actual results could differ.

Cost-Based Regulation. Duke Energy Carolinas accounts for certain of its regulated operations in accordance with applicable regulatory accounting guidance. The economic effects of regulation can
result in a regulated company recording assets for costs that have been or are expected to be approved for recovery from customers in a future period or recording liabilities for amounts that are expected to be returned to customers in the
rate-setting process in a period different from the period in which the amounts would be recorded by a non-regulated enterprise. Accordingly, Duke Energy Carolinas records assets and liabilities that result from the regulated ratemaking process that
would not be recorded under GAAP for non-regulated entities. Regulatory assets and liabilities are amortized consistent with the treatment of the related cost in the ratemaking process. Management continually assesses whether regulatory assets are
probable of future recovery by considering factors such as applicable regulatory changes, recent rate orders applicable to other regulated entities and the status of any pending or potential deregulation legislation. Additionally, management
continually assesses whether any regulatory liabilities have been incurred. Based on this continual assessment, management believes the existing regulatory assets are probable of recovery and that no regulatory liabilities, other than those
recorded, have been incurred. These regulatory assets and liabilities are primarily classified in the Consolidated Balance Sheets as Regulatory Assets and Deferred Debits, and Deferred Credits and Other Liabilities. Duke Energy Carolinas
periodically evaluates the applicability of regulatory accounting treatment, and considers factors such as regulatory changes and the impact of competition. If cost-based regulation ends or competition increases, Duke Energy Carolinas may have to
reduce its asset balances to reflect a market basis less than cost and write off the associated regulatory assets and liabilities. For further information see Note 4.

In order to apply regulatory accounting and record regulatory assets and liabilities, certain scope criteria under applicable regulatory accounting guidance must be met. Management makes significant
judgments in determining whether the scope criteria of the accounting guidance for regulatory accounting are met for its operations, including determining whether revenue rates for services provided to customers are subject to approval by an
independent, third-party regulator, whether the regulated rates are designed to recover specific costs of providing the regulated service, and a determination of whether, in view of the demand for the regulated services and the level of competition,
it is reasonable to assume that rates set at levels that will recover the operations costs can be charged to and collected from customers. This final criterion requires consideration of anticipated changes in levels of demand or competition,
direct and indirect, during the recovery period for any capitalized costs.

Fuel Cost Deferrals. Fuel expense includes
fuel costs or other recoveries that are deferred through fuel clauses established by Duke Energy Carolinas regulators. These clauses allow Duke Energy Carolinas to recover fuel costs, fuel-related costs and portions of purchased power costs
through surcharges on customer rates. These deferred fuel costs are recognized in revenues and fuel expenses as they are billable to customers.

Cash and Cash Equivalents. All highly liquid investments with maturities of three months or less at the date of acquisition are considered cash equivalents.

Restricted Cash. At December 31, 2009 and 2008, Duke Energy Carolinas had approximately $10 million and $25 million,
respectively, of restricted cash related primarily to proceeds from debt issuances that are held in trust for the purpose of funding future environmental construction or maintenance expenditures. Restricted cash balances are reflected within both
Other within Current Assets and Other within Investments and Other Assets on the Consolidated Balance Sheets.



Inventory.Inventory is comprised of amounts presented in the table below and is recorded primarily using the average cost method.
Coal held for electric generation inventory is valued at historical cost consistent with ratemaking treatment. Materials and supplies are recorded as inventory when purchased and subsequently charged to expense or capitalized to plant when
installed.

DUKE ENERGY CAROLINAS, LLC

Notes To Consolidated Financial
Statements(Continued)



Investments in Debt and Equity Securities.Duke Energy Carolinas classifies its
investments as available-for-sale, which are reported at fair value on the Consolidated Balance Sheets with unrealized gains and losses included in Accumulated Other Comprehensive Income (AOCI) or a regulatory asset or liability, unless it is
determined that the carrying value of an investment is other-than-temporarily impaired. Other-than-temporary impairments related to equity securities and the credit loss portion of debt securities are included in earnings, unless deferred in
accordance with regulatory accounting treatment. Investments in debt and equity securities are classified as either short-term investments or long-term investments based on managements intent and ability to sell these securities, taking into
consideration illiquidity factors in the current markets with respect to certain investments that have historically provided for a high degree of liquidity, such as investments in auction rate debt securities.

See Note 10 for further information on the investments in debt and equity securities, including investments held in the Nuclear
Decommissioning Trust Fund (NDTF).

Property, Plant and Equipment. Property, plant and equipment are stated at the
lower of historical cost less accumulated depreciation or fair value, if impaired. Duke Energy Carolinas capitalizes all construction-related direct labor and material costs, as well as indirect construction costs. Indirect costs include general
engineering, taxes and the cost of funds used during construction (see Allowance for Funds Used During Construction (AFUDC) and Interest Capitalized, discussed below). The cost of renewals and betterments that extend the useful life of
property, plant and equipment are also capitalized. The cost of repairs, replacements and major maintenance projects, which do not extend the useful life or increase the expected output of the asset, is expensed as incurred. Depreciation is
generally computed over the estimated useful life of the asset using the composite straight-line method. The composite weighted-average depreciation rates, excluding nuclear fuel, were approximately 2% for 2009 and 3% for 2008 and 2007. Depreciation
studies are conducted periodically to update the composite rates and are approved by the North Carolina Utilities Commission (NCUC) and the Public Service Commission of South Carolina (PSCSC).

When Duke Energy Carolinas retires its regulated property, plant and equipment, it charges the original cost plus the cost of retirement,
less salvage value, to accumulated depreciation. When it sells entire regulated operating units, or retires or sells non-regulated properties, the cost is removed from the property account and the related accumulated depreciation and amortization
accounts are reduced. Any gain or loss is recorded in earnings, unless otherwise required by the applicable regulatory body.

See Note 12 for further information on the components and estimated useful lives of Duke Energy Carolinas property, plant and equipment balance.

AFUDC and Interest Capitalized.In accordance with applicable regulatory accounting guidance, Duke Energy Carolinas records AFUDC, which represents the estimated debt and equity costs of capital
funds necessary to finance the construction of new regulated facilities. Both the debt and equity components of AFUDC are non-cash amounts within the Consolidated Statements of Operations. AFUDC is capitalized as a component of the cost of Property,
Plant and Equipment, with an offsetting credit to Other Income and Expenses, net on the Consolidated Statements of Operations for the equity component and as an offset to Interest Expense on the Consolidated Statements of Operations for the debt
component. After construction is completed, Duke Energy is permitted to recover these costs through inclusion in the rate base and the corresponding depreciation expense or nuclear fuel expense.

AFUDC equity is recorded in the Consolidated Statements of Operations on an after-tax basis and is a permanent difference item for income
tax purposes (i.e., a permanent difference between financial statement and income tax reporting), thus reducing Duke Energys income tax expense and effective tax rate during the construction phase in which AFUDC equity is being recorded. The
effective tax rate is subsequently increased in future periods when the completed property, plant and equipment is placed in service and depreciation of the AFUDC equity commences. See Note 6 for information related to the impacts of AFUDC equity on
Duke Energy Carolinas effective tax rate.

Nuclear Fuel. Amortization of nuclear fuel purchases is included
within Fuel Used in Electric Generation and Purchased Power-Regulated in the Consolidated Statements of Operations. The amortization is recorded using the units-of-production method.



Asset Retirement Obligations. Duke Energy Carolinas
recognizes asset retirement obligations associated with the retirement of long-lived assets that result from the acquisition, construction, development and/or normal use of the asset and for conditional asset retirement obligations. The term
conditional asset retirement obligation refers to a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the entity.
The obligation to perform the asset retirement activity is unconditional even though uncertainty exists about the timing and/or method of settlement. Thus, the timing and/or method of settlement may be conditional on a future event. When recording
an asset retirement obligation, the present value of the projected liability is recognized in the period in which it is incurred, if a reasonable estimate of fair value can be made. The present value of the liability is added to the carrying amount
of the associated asset. This additional carrying amount is then depreciated over the estimated useful life of the asset. See Note 7 for further information regarding Duke Energy Carolinas asset retirement obligations.

Long-Lived Asset Impairments.Duke Energy Carolinas evaluates whether long-lived assets have been impaired when circumstances
indicate the carrying value of those assets may not be recoverable. For such long-lived assets, an impairment exists when its carrying value exceeds the sum of estimates of the undiscounted cash flows expected to result from the use and eventual
disposition of the asset. When alternative courses of action to recover the carrying amount of a long-lived asset are under consideration, a probability-weighted approach is used for developing estimates of future undiscounted cash flows. If the
carrying value of the long-lived asset is not recoverable based on these estimated future undiscounted cash flows, the impairment loss is measured as the excess of the carrying value of the asset over its fair value, such that the assets
carrying value is adjusted to its estimated fair value.

Management assesses the fair value of long-lived assets using
commonly accepted techniques, and may use more than one source. Sources to determine fair value include, but are not limited to, recent third party comparable sales, internally developed discounted cash flow analysis and analysis from outside
advisors. Significant changes in market conditions resulting from events such as, among others, changes in commodity prices or the condition of an asset, or a change in managements intent to utilize the asset are generally viewed by management
as triggering events to re-assess the cash flows related to the long-lived assets.

Unamortized Debt Premium, Discount and
Expense. Premiums, discounts and expenses incurred with the issuance of outstanding long-term debt are amortized over the terms of the debt issues. Any call premiums or unamortized expenses associated with refinancing higher-cost debt
obligations to finance regulated assets and operations are amortized consistent with regulatory treatment of those items, where appropriate. The amortization expense is recorded as a component of interest expense in the Consolidated Statements of
Operations and is reflected as Depreciation and amortization within Net cash provided by operating activities on the Consolidated Statements of Cash Flows.

Notes To Consolidated Financial
Statements(Continued)



Loss Contingencies and Environmental Liabilities.Duke Energy Carolinas is
involved in certain legal and environmental matters that arise in the normal course of business. Contingent losses are recorded when it is determined that it is probable that a loss has occurred and the amount of the loss can be reasonably
estimated. When a range of the probable loss exists and no amount within the range is a better estimate than any other amount, Duke Energy Carolinas records a loss contingency at the minimum amount in the range. Unless otherwise required by GAAP,
legal fees are expensed as incurred.

Environmental liabilities are recorded on an undiscounted basis when the necessity for
environmental remediation becomes probable and the costs can be reasonably estimated, or when other potential environmental liabilities are reasonably estimable and probable. Duke Energy Carolinas expenses environmental expenditures related to
conditions caused by past operations that do not generate current or future revenues. Certain environmental expenses receive regulatory accounting treatment, under which the expenses are recorded as regulatory assets. Environmental expenditures
related to operations that generate current or future revenues are expensed or capitalized, as appropriate.

See Note 14 for
further information.

Pension and Other Post-Retirement Benefit Plans.Duke Energy Carolinas employees
participate in Duke Energys qualified, non-qualified and other post-retirement benefit plans and Duke Energy Carolinas is allocated its proportionate share of benefit costs by Duke Energy. Since Duke Energy Carolinas is not the sponsor for any
of the pension and other post-retirement benefit plans, no amounts related to the funded status of the plans are reflected on Duke Energy Carolinas Consolidated Balance Sheets. See Note 15 for additional information, including certain
accounting policies of Duke Energy associated with these plans.

Severance and Special Termination Benefits.Duke
Energy has an ongoing severance plan under which, in general, the longer a terminated employee worked prior to termination the greater the amount of severance benefits. Duke Energy Carolinas records a liability for involuntary severance once an
involuntary severance plan is committed to by management, or sooner, if involuntary severances are probable and the related severance benefits can be reasonably estimated. For involuntary severance benefits that are incremental to its ongoing
severance plan benefits, Duke Energy Carolinas measures the obligation and records the expense at its fair value at the communication date if there are no future service requirements, or, if future service is required to receive the termination
benefit, ratably over the service period. From time to time, Duke Energy offers special termination benefits under voluntary severance programs. Special termination benefits are measured upon employee acceptance and recorded immediately absent a
significant retention period. If a significant retention period exists, the cost of the special termination benefits are recorded ratably over the remaining service periods of the affected employees. Employee acceptance of voluntary severance
benefits is determined by management based on the facts and circumstances of the special termination benefits being offered.

Revenue Recognition and Unbilled Revenue.Revenues on sales of electricity are recognized when the service is provided. Operating revenues include unbilled electric revenues earned when service has been delivered but not billed by
the end of the accounting period. Unbilled retail revenues are estimated by applying an average revenue per kilowatt-hour(kWh) for all customer classes to the number of estimated kWh delivered but not billed. Unbilled wholesale energy revenues are
calculated by applying the applicable contractual rate per megawatt-hour (MWh) to the number of estimated MWh delivered but not yet billed. Unbilled wholesale demand revenues are calculated by applying the contractual rate per megawatt (MW) to the
MW volume delivered but not yet billed. The amount of unbilled revenues can vary significantly from period to period as a result of numerous factors, including seasonality, weather, customer usage patterns and customer mix. Unbilled revenues, which
are recorded in Receivables on Duke Energy Carolinas Consolidated Balance Sheets at December 31, 2009 and 2008, were approximately $276 million and $234 million, respectively.

Accounting for Risk Management, Hedging Activities and Financial Instruments. Duke Energy Carolinas may use a number of different
derivative and non-derivative instruments in connection with its commodity price and interest rate management activities, which may include swaps, futures, forwards, and options. All derivative instruments not designated as hedges and not qualifying
for the normal purchases and normal sales (NPNS) exception within the accounting guidance for derivatives, are recorded on the Consolidated Balance Sheets at their fair value. Gains and losses on derivatives related to substantially all of Duke
Energy Carolinas operations are deferred as regulatory liabilities and assets, respectively. Duke Energy Carolinas may designate qualifying derivative instruments as either cash flow hedges or fair value hedges, while others either have not been
designated as hedges or do not qualify as a hedge (hereinafter referred to as undesignated contracts).

For all contracts
accounted for as a hedge, Duke Energy Carolinas prepares formal documentation of the hedge in accordance with the accounting guidance for derivatives. In addition, at inception and at least every three months thereafter, Duke Energy formally
assesses whether the hedge contract is highly effective in offsetting changes in cash flows or fair values of hedged items. Duke Energy documents hedging activity by transaction type (futures/swaps) and risk management strategy (commodity price
risk/interest rate risk).

See Note 8 for additional information and disclosures regarding risk management activities and
derivative transactions and balances.

Accounting For Purchases and Sales of Emission Allowances.Emission allowances are issued by the U.S. Environmental Protection Agency (EPA) at zero cost and permit the holder of the allowance to emit certain gaseous by-products of fossil fuel combustion, including sulfur dioxide (SO2) and nitrogen oxide (NOx). Allowances may also be bought and sold via third party transactions or consumed as the emissions are
generated. Allowances allocated to or acquired by Duke Energy Carolinas are held primarily for consumption. Duke Energy Carolinas accounts for emission allowances as intangible assets and records emission allowances as Other within Investments and
Other Assets on its Consolidated Balance Sheets at cost and recognizes the allowances in earnings as they are consumed or sold. Gains and losses on sales of emission allowances are included in Gains on Sales of Other Assets and Other, net in the
Consolidated Statements of Operations, or are deferred, depending on level of regulatory certainty. Purchases and sales of emission allowances are presented gross as investing activities on the Consolidated Statements of Cash Flows.

Income Taxes. Duke Energy Carolinas entered into a tax sharing agreement with Duke Energy, where the separate return method is used
to allocate tax expenses and benefits to the subsidiaries whose investments or results of operations provide these tax expenses or benefits. The accounting for income taxes essentially represents the income taxes that Duke Energy Carolinas would
incur if Duke Energy Carolinas were a separate company filing its own federal tax return as a C-Corporation. Duke Energy Carolinas files separate state income tax returns in North Carolina and South Carolina.

Investment tax credits are deferred and amortized as a reduction of income tax expense over the useful lives of the related property.

Duke Energy Carolinas records unrecognized tax benefits for positions taken or expected to be taken on tax returns, including
the decision to exclude certain income or transactions from a return, when a more-likely-than-not threshold is met for a tax position and management believes that the position will be sustained upon examination by the taxing authorities. Management
evaluates each position based solely on the technical merits and facts and circumstances of the position, assuming the position will be examined by a taxing authority having full knowledge of all relevant information. Duke Energy Carolinas records
the largest amount of the uncertain tax benefit that is greater than 50% likely of being realized upon settlement or effective settlement. Management considers a tax position effectively settled for the purpose of recognizing previously unrecognized
tax benefits when the following conditions exist: (i) the taxing authority has completed its examination procedures, including all appeals and administrative reviews that the taxing authority is required and expected to perform for the tax
positions, (ii) Duke Energy Carolinas does not intend to appeal or litigate any aspect of the tax position included in the completed

examination, and (iii) it is remote that the taxing authority would examine or reexamine any aspect of the tax position. See Note 6 for further information.

Duke Energy Carolinas records, as it relates to taxes, interest expense as Interest Expense and interest income and penalties in Other
Income and Expenses, net, in the Consolidated Statements of Operations.

Excise Taxes. Certain excise taxes levied by
state or local governments are collected by Duke Energy Carolinas from its customers. These taxes, which are required to be paid regardless of Duke Energy Carolinas ability to collect from the customer, are accounted for on a gross basis. When
Duke Energy Carolinas acts as an agent, and the tax is not required to be remitted if it is not collected from the customer, the taxes are accounted for on a net basis. Duke Energy Carolinas excise taxes accounted for on a gross basis and
recorded as revenues in the accompanying Consolidated Statements of Operations were approximately $132 million, $127 million and $132 million for the years ended December 31, 2009, 2008, and 2007, respectively.

Other Current and Non-Current Liabilities. At December 31, 2009 and 2008, approximately $1,552 million and $1,481 million,
respectively, of regulatory liabilities associated with asset removal costs were included in Other Deferred Credits and Other Liabilities in the Consolidated Balance Sheets. At both December 31, 2009 and 2008, this balance exceeded 5% of total
liabilities. Also see Other Litigation and Legal Proceedings in Note 14.

At December 31, 2009 and 2008,
approximately $94 million and $89 million, respectively, of liabilities associated with vacation accrued were included in Other Current Liabilities in the Consolidated Balance Sheets. At December 31, 2008, this balance exceeded 5% of total
current liabilities.

New Accounting Standards. The following new accounting standards were adopted by Duke Energy
Carolinas during the year ended December 31, 2009 and the impact of such adoption, if applicable, has been presented in the accompanying Consolidated Financial Statements:

Financial Accounting Standards Boards (FASB) Accounting Standards Codification (ASC) 105Generally Accepted Accounting
Principles (ASC 105). In June 2009, the FASB amended ASC 105 for the ASC, which identifies the sources of accounting principles and the framework for selecting the principles used in the preparation of financial statements of nongovernmental
entities that are presented in conformity with GAAP. Rules and interpretive releases of the Securities and Exchange Commission (SEC) under authority of federal securities laws are also sources of authoritative GAAP. On the effective date of the
changes to ASC 105, which was for financial statements issued for interim and annual periods ending after September 15, 2009, the ASC supersedes all then-existing non-SEC accounting and reporting standards. Under the ASC, all of its content
carries the same level of authority and the GAAP hierarchy includes only two levels of GAAP: authoritative and non-authoritative. While the adoption of the ASC did not have an impact on the accounting followed in Duke Energy Carolinas
consolidated financial statements, the ASC impacted the references to authoritative and non-authoritative accounting literature contained within the Notes.

ASC 805Business Combinations (ASC 805). In December 2007, the FASB issued revised guidance related to the accounting for business combinations. This revised guidance retained the fundamental
requirement that the acquisition method of accounting be used for all business combinations and that an acquirer be identified for each business combination. This statement also established principles and requirements for how an acquirer recognizes
and measures in its financial statements the identifiable assets acquired, the liabilities assumed, any noncontrolling (minority) interests in an acquiree, and any goodwill acquired in a business combination or gain recognized from a bargain
purchase. For Duke Energy Carolinas, this revised guidance is applied prospectively to business combinations for which the acquisition date occurred on or after January 1, 2009. The impact to Duke Energy Carolinas of applying this revised
guidance for periods subsequent to implementation will be dependent upon the nature of any transactions within the scope of ASC 805.

ASC 815Derivatives and Hedging (ASC 815).In March 2008, the FASB amended and expanded the disclosure requirements for derivative instruments and hedging activities required under ASC 815. The amendments to ASC 815 requires
qualitative disclosures about objectives and strategies for using derivatives, volumetric data, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent
features in derivative agreements. Duke Energy adopted these disclosure requirements as of January 1, 2009. The adoption of the amendments to ASC 815 did not have any impact on Duke Energy Carolinas consolidated results of operations,
cash flows or financial position. See Note 8 for the disclosures required under ASC 815.

The following new accounting
standards were adopted by Duke Energy Carolinas during the year ended December 31, 2008 and the impact of such adoption, if applicable, has been presented in the accompanying Consolidated Financial Statements:

ASC 820  Fair Value Measurements and Disclosures (ASC 820).Refer to Note 9 for required fair value disclosures.

ASC 825  Financial Instruments (ASC 825).ASC 825 permits, but does not require, entities to elect to measure many financial
instruments and certain other items at fair value. See Note 9.

The following new accounting standard was adopted by Duke
Energy Carolinas during the year ended December 31, 2007 and the impact of such adoption, if applicable, has been presented in the accompanying Consolidated Financial Statements:

ASC 740  Income Taxes (ASC 740). In July 2006, the FASB provided new guidance on accounting for income tax positions about
which Duke Energy Carolinas has concluded there is a level of uncertainty with respect to the recognition of a tax benefit in Duke Energy Carolinas financial statements. This guidance prescribed the minimum recognition threshold a tax position
is required to meet. Tax positions are defined very broadly and include not only tax deductions and credits but also decisions not to file in a particular jurisdiction, as well as the taxability of transactions. Duke Energy Carolinas adopted this
new accounting guidance effective January 1, 2007. See Note 6 for additional information.

The following new accounting
standard has been issued, but has not yet been adopted by Duke Energy Carolinas, as of December 31, 2009:

ASC 810
In June 2009, the FASB amended existing consolidation accounting guidance to eliminate the exemption from consolidation for qualifying special-purpose entities (QSPEs), and clarified, but did not significantly change, the criteria
for determining whether an entity meets the definition of a variable interest entity (VIE). This revised accounting guidance also requires an enterprise to qualitatively assess the determination of the primary beneficiary of a VIE based on whether
that enterprise has both the power to direct matters that most significantly impact the activities of a VIE and the obligation to absorb losses or the right to receive benefits of a VIE that could potentially be significant to a VIE. In addition,
this revised accounting guidance modifies existing accounting guidance to require an ongoing evaluation of a VIEs primary beneficiary and amends the types of events that trigger a reassessment of whether an entity is a VIE. Furthermore, this
accounting guidance requires enterprises to provide additional disclosures about their involvement with VIEs and any significant changes in their risk exposure due to that involvement. For Duke Energy Carolinas, this accounting guidance is effective
beginning on January 1, 2010, and is applicable to all entities in which Duke Energy Carolinas is involved with, including entities previously subject to existing accounting guidance for VIEs, as well as any QSPEs that exist as of the effective
date. Early adoption of this revised accounting guidance is prohibited. Duke Energy Carolinas is currently evaluating the potential impact of the adoption of this revised accounting guidance on its interest in VIEs and is unable to estimate at this
time the impact of adoption on its consolidated results of operations, cash flows or financial position.

2. Business Segments

Duke Energy Carolinas operates one reportable business segment, Franchised Electric, which generates, transmits, distributes and sells
electricity and conducts operations through Duke Energy Carolinas, which consists of the regulated electric utility businesses in North Carolina and South Carolina. Duke Energy Carolinas chief operating decision maker regularly reviews
financial information about the business unit in deciding how to allocate resources and evaluate performance. There is no aggregation within the Franchised Electric business segment.

The remainder of Duke Energy Carolinas operations is presented as Other. While it is not considered a business segment, Other
primarily includes certain allocated corporate governance costs.

Management evaluates segment performance based on earnings
before interest and taxes from continuing operations (EBIT). On a segment basis, EBIT excludes discontinued operations and represents all profits from continuing operations (both operating and non-operating and excluding corporate governance costs)
before deducting interest and taxes.

Cash, cash equivalents and short-term investments are managed centrally by Duke Energy,
so the associated interest and dividend income on those balances are excluded from segment EBIT.

Restrictions on the Ability of Duke Energy Carolinas to Make Dividends, Advances and Loans to Duke Energy Corporation. On
April 3, 2006, the merger of Duke Energy and Cinergy was consummated. As a condition of the merger approval the state utility commissions imposed conditions (the Merger Conditions) on the ability of Duke Energy Carolinas to transfer funds to
Duke Energy through loans or advances as well as restricted amounts available to pay dividends to Duke Energy. Duke Energy Carolinas must limit cumulative distributions to Duke Energy Corporation subsequent to the merger to (i) the amount of
retained earnings on the day prior to the closing of the merger, plus (ii) any future earnings recorded by Duke Energy Carolinas subsequent to the merger. At December 31, 2009, Duke Energy Carolinas

had restricted net assets of approximately $3.8 billion that cannot be transferred to Duke Energy via dividend or loan based on the aforementioned merger conditions.

Rate Related Information. The NCUC and PSCSC approve rates for retail electric services within their states. The Federal
Energy Regulatory Commission (FERC) approves rates for electric sales to wholesale customers served under cost-based and market-based rates.

Duke Energy Carolinas 2007 North Carolina Rate Case. On December 20, 2007, the NCUC issued its Order Approving Stipulation and Deciding Non-Settled Issues (Order), which required that
Duke Energy Carolinas test period for operating costs reflect an annualized level of the merger cost savings actually experienced in the test period. However, the NCUC recognized that its treatment of merger savings would not produce a fair
result. Therefore, on February 18, 2008 the NCUC issued an order authorizing a 12-month increment rider, beginning January 2008, of approximately $80 million designed to provide a more equitable sharing of the actual merger savings achieved on
an ongoing basis. Duke Energy Carolinas implemented the rate rider effective January 1, 2008 and terminated the rider effective January 1, 2009. The Order ultimately resulted in an overall average rate decrease of 5% in 2008, increasing to
7% upon expiration of this one-time rate rider.

Duke Energy Carolinas 2009 North Carolina Rate Case. On
June 2, 2009, Duke Energy Carolinas filed an Application for Adjustment of Rates and Charges Applicable to Electric Service in North Carolina to increase its base rates. The Application was based upon a historical test year consisting of the 12
months ended December 31, 2008. On October 20, 2009, Duke Energy Carolinas entered into a settlement agreement with the North Carolina Public Staff. Two organizations representing industrial customers joined the settlement on
October 22, 2009. The terms of the agreement include a base rate increase of $315 million (or approximately 8%) phased in primarily over a two-year period beginning January 1, 2010. In order to mitigate the impact of the increase on
customers, the agreement provides for (i) a one-year delay in the collection of financing costs related to the Cliffside modernization project until January 1, 2011; and (ii) the accelerated return of certain regulatory liabilities to
customers which lower the total impact to customer bills to an increase of approximately 7% in the near-term. The proposed settlement included a 10.7% return on equity and a capital structure of 52.5% equity and 47.5% long-term
debt. Additionally, Duke Energy Carolinas agreed not to file another rate case before 2011 with any changes to rates taking effect no sooner than 2012. The NCUC approved the settlement agreement in full by order dated December 7, 2009. The
new rates were effective and implemented on January 1, 2010.

Duke Energy Carolinas 2009 South Carolina Rate
Case. On July 27, 2009, Duke Energy Carolinas filed its Application for Authority to Increase and Adjust Rates and Charges for an increase in rates and charges in South Carolina including approval of a charge to customer bills to
pay for Duke Energy Carolinas new energy efficiency efforts. Parties to the proceeding include the South Carolina Office of Regulatory Staff (ORS), the South Carolina Energy Users Committee (SCEUC), and the South Carolina Green Party. Duke
Energy Carolinas, ORS, and SCEUC filed a settlement agreement on November 24, 2009, recommending, (i) a $74 million increase in base rates, (ii) an allowed return on equity of 11% with rates set at a return on equity of 10.7% and
capital structure of 53% equity, and (iii) various riders, including one that provides for the return of Demand Side Management charges previously collected from customers over three years, and another that provides for a storm reserve
provision allowing Duke Energy Carolinas to collect $5 million annually (up to a maximum funding level of $50 million accumulating in reserves) to be used against large storm costs in any particular period. On January 20, 2010, the PSCSC
approved the settlement agreement in full, including the cost recovery mechanism for the energy efficiency effort. The new rates were effective February 1, 2010.

Energy Efficiency.On May 7, 2007, Duke Energy Carolinas filed its save-a-watt application with the NCUC. The save-a-watt proposal is based on the avoided cost of generation not
needed resulting from any successful Duke Energy Carolinas energy efficiency programs. On February 26, 2009, the NCUC issued an order (i) approving Duke Energy Carolinas energy efficiency programs; (ii) requesting additional
information on Duke Energy Carolinas returns under eight different compensation scenarios; and (iii) authorizing Duke Energy Carolinas to implement its rate rider pending approval of a final compensation mechanism by the NCUC. Duke Energy
Carolinas filed the additional information requested by the NCUC on March 31, 2009. On June 12, 2009, Duke Energy Carolinas filed with the NCUC a settlement agreement between Duke Energy Carolinas and the Public Staff and several
environmental intervenors. A hearing on the settlement was held on August 19, 2009. A Notice of Decision approving the settlement with modifications was issued on December 14, 2009. Duke Energy Carolinas began offering energy conservation
programs to North Carolina retail customers and billing a conservation-only rider on June 1, 2009. On February 10, 2010, the NCUC approved the order in full.

In mid-October 2009, Duke Energy Carolinas began offering demand response programs in North Carolina. On January 1, 2010, Duke Energy Carolinas began to bill the full Rider Energy Efficiency approved
by the NCUC in its December 14, 2009 Notice of Decision.



On May 6, 2009, the PSCSC approved Duke Energy Carolinas request for (i) approval of conservation and demand response programs; (ii) cancellation of certain existing demand response
programs; (iii) deferral of the costs incurred to develop and implement the energy efficiency programs from June 1, 2009 until the date these costs are reflected in electric rates; and (iv) assurance that Duke Energy Carolinas may
true-up incentives for costs deferred pursuant to the petition in accordance with the PSCSC order on the appropriate compensation mechanism in Duke Energy Carolinas 2009 general rate proceeding. Duke Energy Carolinas began offering demand
response and conservation programs to South Carolina retail customers effective June 1, 2009. As described above, on January 20, 2010, the PSCSC approved Duke Energy Carolinas cost recovery mechanism for energy efficiency. The new
rates were effective February 1, 2010.

The save-a-watt programs and compensation approach in both North Carolina and
South Carolina are approved through December 31, 2013.

Renewable Resources. On June 6, 2008,
Duke Energy Carolinas filed an application with the NCUC seeking approval to implement a solar photovoltaic distributed generation program (Program). Duke Energy Carolinas proposed to invest $100 million over two years to install a total of 20 MW of
electricity generating solar panels on multiple North Carolina sites including homes, schools, stores and factories. The Program will help Duke Energy Carolinas meet the requirement of North Carolinas Renewable Energy and Energy Efficiency
Portfolio Standard (REPS). It will also enable Duke Energy Carolinas to evaluate the role of distributed generation on Duke Energy Carolinas electrical system and gain experience in owning and operating renewable energy resources. Because the
Program involves the construction of electric generating facilities, Duke Energy Carolinas required a Certificate of Public Convenience and Necessity (CPCN) from the NCUC. The REPS statute provides for the recovery of costs Duke Energy Carolinas
incurs to comply with its requirements, principally through an annual rate rider.

In response to concerns raised by the
Public Staff and various solar energy groups, Duke Energy Carolinas agreed to reduce the size of the Program to invest $50 million to install up to 10 MW of solar photovoltaic capacity. On December 31, 2008, the NCUC issued its Order Granting
CPCN Subject to Conditions. The conditions (i) reduce the program size from 20 MW to 10 MW (as previously agreed upon by Duke Energy Carolinas); and (ii) limit program costs recoverable through the REPS rider to program costs equivalent to
the cost of the third place bid in Duke Energy Carolinas 2007 request for proposal for renewable energy. The Order left open the opportunity to recover the excess costs through other recovery mechanisms. Based upon the

revised size and availability of state and federal credits, Duke Energy Carolinas estimates the limited amount of program costs recoverable through the REPS rider will result in a monthly charge
of approximately $0.05 for residential customers.

On May 6, 2009, in response to Duke Energy Carolinas request for
reconsideration, the NCUC issued an Order allowing Duke Energy Carolinas to proceed with the Program and allowed Duke Energy Carolinas to recover all costs incurred in executing the Program through a combination of the REPS rider and base rates,
subject to the NCUCs review of the reasonableness and prudence of Duke Energy Carolinas execution of the Program. However, the NCUC declined to remove the limitation on costs recoverable through the REPS rider.

Deferral of Costs. On February 4, 2009, Duke Energy Carolinas filed petitions with the NCUC and the PSCSC requesting an
accounting order to defer the incremental costs incurred from the September 2008 purchase of an additional ownership interest in the Catawba Nuclear Station and certain post-in-service costs that are being or will be incurred in connection with the
addition of the Allen Steam Station flue gas desulfurization equipment related to environmental compliance scheduled to go into service in the spring of 2009. The costs Duke Energy Carolinas sought to defer are the incremental costs that are being
incurred or will be incurred from the date these assets are placed in service to the date Duke Energy Carolinas is authorized to begin reflecting in rates the recovery of such costs on an ongoing basis. On February 25, 2009, and March 31,
2009, the PSCSC and NCUC, respectively, approved the deferral of these costs. Duke Energy Carolinas began deferring costs in the first quarter 2009. These costs are being recovered in the new rates effective January 1, 2010 for North Carolina,
and effective February 1, 2010, for South Carolina.

Broad River Energy Center.On August 25, 2007,
Duke Energy Carolinas experienced a disturbance on its bulk electric system which initiated at the Broad River Energy Center, a generating station owned and operated by a third party. The disturbance resulted in the tripping of six Duke Energy
Carolinas generating units and the temporary opening of five 230 kilovolt (KV) transmission lines. The event resulted in no loss of load. In September 2008 the FERC initiated a preliminary, non-public investigation to determine if there were
any potential violations by Duke Energy Carolinas of the North American Electric Reliability Council Reliability Standards. This investigation was coordinated with an ongoing Compliance Violation Investigation conducted by SERC Reliability
Corporation. On March 5, 2009, FERC presented its preliminary findings about the event to Duke Energy Carolinas and solicited Duke Energy Carolinas responsive views about the event and the findings. On March 27, 2009, Duke
Energy Carolinas conveyed its responsive views to FERC Staff. This investigation could result in penalties being assessed.

Capital
Expansion Projects

Overview. Duke Energy Carolinas is engaged in planning efforts to meet projected
load growth in its service territories. Capacity additions may include new nuclear, coal facilities or gas-fired generation units. Because of the long lead times required to develop such assets, Duke Energy Carolinas is taking steps now to ensure
those options are available.

William States Lee III Nuclear Station. On December 12, 2007, Duke Energy
Carolinas filed an application with the Nuclear Regulatory Commission (NRC), which has been docketed for review, for a Combined Construction and Operating License (COL) for two Westinghouse AP1000 (advanced passive) reactors for the proposed William
States Lee III Nuclear Station at a site in Cherokee County, South Carolina. Each reactor is capable of producing approximately 1,117 MW. Submitting the COL application does not commit Duke Energy Carolinas to build nuclear units. On
December 7, 2007, Duke Energy Carolinas filed applications with the NCUC and the PSCSC for approval of Duke Energy Carolinas decision to incur development costs associated with the proposed William States Lee III Nuclear Station. The NCUC
had previously approved Duke Energys decision to incur the North Carolina allocable share of up to $125 million in development costs through 2007. The 2007 requests cover a total of up to $230 million in development costs through 2009, which
is comprised of $70 million incurred through December 31, 2007 plus an additional $160 million of anticipated costs in 2008 and 2009. The PSCSC approved Duke Energy Carolinas William States Lee III Nuclear project development cost
application on June 9, 2008, and the NCUC issued its approval order on June 11, 2008. On July 24, 2008, environmental intervenors filed motions to rescind or amend the approval orders issued by the NCUC and the PSCSC, and Duke Energy
Carolinas subsequently filed responses in opposition to the motions. On August 13 and August 25, 2008, the PSCSC and NCUC, respectively, denied the environmental intervenor motion. The NRC review of the COL application continues and the
estimated receipt of the COL is in mid 2013. Duke Energy Carolinas filed with the Department of Energy (DOE) for a federal loan guarantee, which has the potential to significantly lower financing costs associated with the proposed William States Lee
III Nuclear Station; however, it was not among the four projects selected by the DOE for the final phase of due diligence for the federal loan guarantee program. The project could be selected in the future if the program funding is expanded or if
any of the current finalists drop out of the program.



South Carolina passed new energy legislation (S 431) which became effective May 3, 2007. The legislation includes provisions to provide assurance of cost recovery related to a utilitys incurrence of project development costs
associated with nuclear baseload generation, cost recovery assurance for construction costs associated with nuclear or coal baseload generation, and the ability to recover financing costs for new nuclear baseload generation in rates during
construction through a rider. The North Carolina General Assembly also passed comprehensive energy legislation North Carolina Senate Bill 3 (SB 3) in July 2007 that was signed into law by the Governor on August 20, 2007. Like the South Carolina
legislation, the North Carolina legislation provides cost recovery assurance, subject to prudency review, for nuclear project development costs as well as baseload generation construction costs. A utility may include financing costs related to
construction work in progress for baseload plants in a rate case.

Cliffside Unit 6.On June 2,
2006, Duke Energy Carolinas filed an application with the NCUC for a CPCN to construct two 800 MW state of the art coal generation units at its existing Cliffside Steam Station in North Carolina. On March 21, 2007, the NCUC issued an Order
allowing Duke Energy Carolinas to build one 800 MW unit. On February 20, 2008, Duke Energy Carolinas entered into an amended and restated engineering, procurement, construction and commissioning services agreement, valued at approximately $1.3
billion, with an affiliate of The Shaw Group, Inc., of which approximately $950 million relates to participation in the construction of Cliffside Unit 6, with the remainder related to a flue gas desulfurization system on an existing unit at
Cliffside. On February 27, 2009, Duke Energy Carolinas filed its latest updated cost estimate of $1.8 billion (excluding up to approximately $0.6 billion of AFUDC) for the approved new Cliffside Unit 6. Duke Energy Carolinas believes that the
overall cost of Cliffside Unit 6 will be reduced by approximately $125 million in federal advanced clean coal tax credits, as discussed further below.

On January 29, 2008, the North Carolina Department of Environment and Natural Resources (DENR) issued a final air permit for the new Cliffside Unit 6 and on-site construction has begun. In March
2008, four contested case petitions, which have since been consolidated, were filed appealing the final air permit. On May 12, 2009, the Administrative Law Judge issued rulings favorable to DENR and Duke Energy, dismissing several of
petitioners claims and granting summary judgment against petitioners on other claims, resulting in the dismissal of two petitions and leaving two for hearing. A hearing on remaining claims is scheduled for June 2010. See Note 14 for a
discussion of a lawsuit filed by the Southern Alliance for Clean Energy, Environmental Defense Fund, National Parks Conservation Association, Natural Resources Defenses Council, and Sierra Club (collectively referred to as Citizen Groups) related to
the construction of Cliffside Unit 6.

On October 14, 2008, Duke Energy Carolinas submitted revised hazardous air
pollutant (HAPs) emissions determination documentation including revised emission source information to the Division of Air Quality (DAQ) indicating that no maximum achievable control technology (MACT) or MACT-like requirements apply since Cliffside
Unit 6 has been demonstrated to be a minor source of HAPs.

After issuing a draft permit and holding public hearings on that
draft permit in January 2009, the DAQ issued the revised permit on March 13, 2009, finding that Cliffside Unit 6 is a minor source of HAPs and imposing operating conditions to assure that emissions stay below the major source threshold. In May
2009, four contested case petitions were filed appealing the March 13, 2009 final air permit. These four cases have been consolidated with each other and with the four consolidated cases filed in 2008, resulting in the dismissal of two of the
four cases. The same schedule will govern these cases with a hearing scheduled for June 2010.

Dan River and Buck
Combined Cycle Facilities. On June 29, 2007, Duke Energy Carolinas filed with the NCUC preliminary CPCN information to construct a 620 MW combined cycle natural gas-fired generating facility at its existing Dan River Steam
Station, as well as updated preliminary CPCN information to construct a 620 MW combined cycle natural gas-fired generating facility at its existing Buck Steam Station. On December 14, 2007, Duke Energy Carolinas filed CPCN applications for the
two combined cycle facilities. The NCUC consolidated its consideration of the two CPCN applications and held an evidentiary hearing on the applications on March 11, 2008. The NCUC issued its order approving the CPCN applications for the Buck
and Dan River combined cycle projects on June 5, 2008. On May 5, 2008, Duke Energy Carolinas entered into an engineering, construction and commissioning services agreement for the Buck combined cycle project, valued at approximately $275
million, with Shaw North Carolina, Inc. (Shaw). On November 5, 2008, Duke Energy Carolinas notified the NCUC that since the issuance of the CPCN Order, recent economic factors have caused increased uncertainty with regard to forecasted load and
near-term capital expenditures, resulting in a modification of the construction schedule. On September 1, 2009, Duke Energy Carolinas filed with the NCUC further information clarifying the construction schedule for the two projects. Under the
revised schedule, the Buck Project is expected to begin operation in combined cycle mode by the end of 2011, but without a phased-in simple cycle commercial operation. The Dan River Project is expected to begin operation in combined cycle mode by
the end of 2012, also without a phased-in simple cycle commercial operation. On December 21, 2009, Duke Energy Carolinas entered into a First Amended and Restated engineering, construction and commissioning services agreement with Shaw for $322
million which reflects the revised schedule. On March 8, 2010, Duke Energy Carolinas entered into an engineering, construction and commissioning services agreement with Shaw for the construction of the Dan River Project for approximately $325
million. Based on the most updated cost estimates, total costs (including AFUDC) for the Buck and Dan River projects are approximately $660 million and $710 million, respectively.

On October 15, 2008, the DAQ issued a final air permit authorizing construction of the Buck combined cycle natural gas-fired generating
units, and on August 24, 2009, the DAQ issued a final air permit authorizing construction of the Dan River combined cycle natural gas-fired generation units.

Federal Advanced Clean Coal Tax Credits. Duke Energy Carolinas has been awarded approximately $125 million of federal advanced clean coal tax credits associated with its construction of
Cliffside Unit 6. In March 2008, two environmental groups, Appalachian Voices and the Canary Coalition, filed suit against the Federal government challenging the tax credits awarded to incentivize certain clean coal projects. Although Duke Energy
Carolinas was not a party to the case, the allegations center on the tax incentives provided for Duke Energy Carolinas Cliffside project. The initial complaint alleged a failure to comply with the National Environmental Policy Act. The first
amended complaint, filed in August 2008, added an Endangered Species Act claim and also sought declaratory and injunctive relief against the DOE and the U.S. Department of the Treasury. On November 10, 2008, the District Court dismissed the
case. On September 23, 2009, the District Court issued an order, granting plaintiffs motion to amend their complaint and denying, as moot, the motion for reconsideration. Plaintiffs have filed their second amended complaint. The Federal
government has moved to dismiss the second amendment complaint; the motion is pending.



Other Matters

City of Orangeburg, South Carolina Wholesale Sales.On June 28, 2008, Duke Energy Carolinas filed notice with the NCUC that it intended to sell electricity to the City of Orangeburg, South Carolina (City of Orangeburg), a wholesale customer, at native load priority. Duke Energy Carolinas
and the City of Orangeburg also filed a joint petition asking the NCUC to declare that the City of Orangeburg contract and all future Duke Energy Carolinas native load priority wholesale contracts will be treated for ratemaking and reporting
purposes in the same manner as such existing wholesale contracts (i.e., revenues from those contracts will be allocated to wholesale jurisdiction and costs will be allocated to wholesale jurisdiction based on system average costs). On March 30,
2009, the NCUC issued its Order in which it concluded that Duke Energy Carolinas can proceed with the City of Orangeburg contract at its own risk; however, Duke Energy Carolinas cannot treat the City of Orangeburgs load as Duke Energy
Carolinas native load for rate setting purposes. Further, the NCUC concluded that based on the evidence presented, a future Commission should allocate costs based upon incremental costs in any future ratemaking case. The NCUC distinguished the
City of Orangeburg from wholesale customers that have been historically served by Duke Energy Carolinas because the City of Orangeburg has not shared in the costs of Duke Energy Carolinas existing system. Due to the NCUC ruling, Duke Energy
Carolinas terminated the system average contract with the City of Orangeburg in April 2009 per the allowed contractual provisions. The City of Orangeburg then terminated its contingency contract with Duke Energy Carolinas at incremental pricing
and informed Duke Energy Carolinas that it would take service from South Carolina Electric and Gas Company via a newly executed agreement through the end of 2010. On April 29, 2009, Duke Energy Carolinas and the City of Orangeburg filed a
Notice of Appeal with the North Carolina Court of Appeals and briefs were filed with the Court of Appeals on December 16, 2009. The City of Fayetteville and ElectriCities filed briefs in support of Duke Energy Carolinas and City of
Orangeburgs positions. Briefs for the appellees are due on February 17, 2010. Additionally, on July 2, 2009, the City of Orangeburg filed a Petition for Declaratory Order with the FERC seeking relief from the NCUC Order on various
grounds, including violation of the Public Utility Regulatory Policies Act voluntary coordination provisions and federal preemption. The NCUC, the Public Staff and the Attorney General, Progress Energy, the National Association of Regulatory Utility
Commissioners, Occidental Power Marketing and the North Carolina Waste Awareness Network (WARN) have intervened in opposition to the Petition. The City of Fayetteville and ElectriCities, have intervened in favor of Orangeburgs position, as has
the American Public Power Association. Duke Energy Carolinas and NC Electric Membership Cooperative have also intervened, but expressed no position on the Petition.

Wholesale Sales.On September 3, 2009, Duke Energy Carolinas filed advance notice of its intent to serve Central Electric Power Cooperative, Inc. as an additional wholesale customer at
native load priority and at system average cost. The load to be served consists of load historically served by Duke Energy Carolinas until recently. On September 11, 2009, the Public Staff filed its response to the advance notice, indicating
that it did not object to the advance notice filing and further indicating that it was unlikely that the Public Staff would in a future rate proceeding recommend that costs associated with the Central Electric Power cooperative, Inc. contract be
allocated on anything other than system average cost. On October 5, 2009, the WARN filed a petition to intervene in the proceeding arguing that the extension of Duke Energy Carolinas service area through wholesale sales is not in the best
interests of Duke Energy Carolinas customers. On November 10, 2009, the NCUC issued an order rejecting WARNs objection and permitting Duke Energy Carolinas to proceed with the proposed agreement.

Duke Energy Carolinas has also filed advance notices of its intent to serve additional
wholesale customers; namely, the City of Greenwood, South Carolina and Haywood Electric Membership Corp., at native load priority. Given that these wholesale customers were historically served by Duke Energy Carolinas for a portion of their load,
Duke Energy Carolinas will seek to distinguish these contracts from the Orangeburg decision. On July 20, 2009, the NCUC issued an order concluding that Duke Energy Carolinas can proceed with the Greenwood purchased power agreement and that
Greenwoods load may be treated the same as retail native load.

5. Joint Ownership of Generating Facilities

Duke Energy Carolinas, along with North Carolina Municipal Power Agency Number 1, North Carolina Electric Membership Corporation and Piedmont
Municipal Power Agency, have joint ownership of Catawba Nuclear Station, which is a facility operated by Duke Energy Carolinas. As discussed in Note 3, in September 2008, Duke Energy Carolinas completed the purchase of a portion of Saludas
ownership interest in the Catawba Nuclear Station. Under the terms of the agreement, Duke Energy Carolinas paid approximately $150 million for an additional approximate 7 percent ownership interest in the Catawba Nuclear Station.

Duke Energy Carolinas share of the Catawba jointly-owned plant included on the December 31, 2009 Consolidated Balance Sheet was
as follows:

Duke Energy
Carolinas share of revenues and operating costs of the Catawba Nuclear Station is included within the corresponding line on the Consolidated Statements of Operations. Each participant in the jointly owned facility must provide its own
financing.

6. Income Taxes

The taxable income of Duke Energy Carolinas is reflected in Duke Energys U.S. federal and state income tax returns. Duke Energy Carolinas has a tax sharing agreement with Duke Energy where the
separate return method is used to allocate tax expenses and benefits to the subsidiaries whose investments or results of operations provide these tax expenses and benefits. The accounting for income taxes essentially represents the income taxes that
Duke Energy Carolinas would incur if Duke Energy Carolinas were a separate company filing its own tax return as a C-Corporation.

The following details the components of income tax expense:

At December 31, 2009, Duke Energy Carolinas has approximately $286 million of unrecognized tax benefit
that, if recognized, may affect the effective tax rate or a regulatory liability. At this time, Duke Energy Carolinas is unable to estimate the specific effect to either. It is reasonably possible that Duke Energy Carolinas will reflect an
approximate $300 million reduction in unrecognized tax benefits within the next 12 months due to expected settlements.

During
the years ended December 31, 2009, 2008 and 2007, Duke Energy Carolinas recognized no net interest income or expense, approximately $2 million of net interest expense and approximately $40 million of net interest income, respectively, related
to income taxes. At both December 31, 2009 and 2008, Duke Energy Carolinas Consolidated Balance Sheets included approximately $32 million of interest receivable related to income taxes. No amounts have been recorded for the payment of
penalties.

Duke Energy Carolinas has the following tax years open:

included in Other within Current Assets in the Consolidated Balance Sheets. At December 31, 2008, this balance exceeded 5% of total current assets.

7. Asset Retirement Obligations

Asset retirement obligations, which
represent legal obligations associated with the retirement of certain tangible long-lived assets, are computed as the present value of the projected costs for the future retirement of specific assets and are recognized in the period in which the
liability is incurred, if a reasonable estimate of fair value can be made. The present value of the liability is added to the carrying amount of the associated asset in the period the liability is incurred, and this additional carrying amount is
depreciated over the remaining life of the asset. Subsequent to the initial recognition, the liability is adjusted for any revisions to the estimated future cash flows associated with the asset retirement obligation (with corresponding adjustments
to property, plant, and equipment), which can occur due to a number of factors including, but not limited to, cost escalation, changes in technology applicable to the assets to be retired and changes in federal, state or local regulations, as well
as for accretion of the liability due to the passage of time until the obligation is settled. Depreciation expense is adjusted prospectively for any increases or decreases to the carrying amount of the associated asset. The recognition of asset
retirement obligations has no impact on the earnings of Duke Energy Carolinas regulated electric operations as the effects of the recognition and subsequent accounting for an asset retirement obligation are offset by the establishment of
regulatory assets and liabilities pursuant to regulatory accounting.

Asset retirement obligations recognized by Duke Energy
Carolinas relate primarily to the decommissioning of nuclear power facilities, obligations related to asbestos removal and landfills at fossil generation facilities. Certain of Duke Energy Carolinas assets have an indeterminate life, such as
transmission and distribution facilities and some gas-fired power plants and thus the fair value of the retirement obligation is not reasonably estimable. A liability for these asset retirement obligations will be recorded when a fair value is
determinable.

|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(c) | As discussed below, Duke Energy updates its nuclear decommissioning costs study every five years as required by the NCUC and PSCSC. The increase in the revisions
to estimated cash flows primarily relates to the increase in estimated cost of decommissioning Duke Energys nuclear units. Approximately half of the increase in the nuclear decommissioning cost estimates is due to increased labor costs since
the completion of the previous cost study in 2003. The change in the credit-adjusted risk-free rate since the 2003 study also impacted the determination of the asset retirement obligation liability associated with nuclear decommissioning.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Duke Energy Carolinas regulated electric operations accrue costs of removal for property that does not
have an associated legal retirement obligation based on regulatory orders from the various state commissions. These costs of removal are recorded as a regulatory liability in accordance with regulatory accounting treatment. Duke Energy Carolinas
does not accrue the estimated cost of removal when no legal obligation associated with retirement or removal exists for any non-regulated assets. The total amount of cost of removal for assets without an associated legal retirement obligation, which
are included in Other within Deferred Credits and Other Liabilities on the Consolidated Balance Sheets, was $1,552 million and $1,481 million as of December 31, 2009 and 2008, respectively.

Nuclear Decommissioning Costs.In 2005, the NCUC and PSCSC approved a $48 million annual amount for contributions and expense levels
for decommissioning. In each of the years ended December 31, 2009, 2008 and 2007, Duke Energy expensed approximately $48 million and contributed cash of approximately $48 million to the NDTF for decommissioning costs. These amounts are
presented in the Consolidated Statements of Cash Flows in Purchases of Available-For-Sale Securities within Net Cash Used in Investing Activities. The entire amount of these contributions were to the funds reserved for contaminated costs as
contributions to the funds reserved for non-contaminated costs have been discontinued since the current estimates indicate existing funds to be sufficient to cover projected future costs. Both the NCUC and the PSCSC have allowed Duke Energy to
recover estimated decommissioning costs through retail rates over the expected remaining service periods of Duke Energys nuclear stations. Duke Energy believes that the decommissioning costs being recovered through rates, when coupled with
expected fund earnings, will be sufficient to provide for the cost of future decommissioning.

The balance of the external
nuclear decommissioning trust funds, which are reflected as Nuclear Decommissioning Trust Funds within Investments and Other Assets in the Consolidated Balance Sheets, was approximately $1,765 million as of December 31, 2009 and $1,436 million
as of December 31, 2008. The increase in the value of the NDTF during 2009 is due to higher overall returns in the equity and debt markets. The fair value of assets legally restricted for the purpose of settling asset retirement obligations
associated with nuclear decommissioning was $1,530 million as of December 31, 2009 and $1,194 million as of December 31, 2008.

As the NCUC and the PSCSC require that Duke Energy update its cost estimate for decommissioning its nuclear plants every five years, new site-specific nuclear decommissioning cost studies were completed
in January 2009 that showed total estimated nuclear decommissioning costs, including the cost to decommission plant components not subject to radioactive contamination, of approximately $3 billion in 2008 dollars. This estimate includes Duke
Energys approximate 19% ownership interest in the Catawba Nuclear Station. The other joint owners of Catawba Nuclear Station are responsible for decommissioning costs related to their ownership interests in the station. The previous study,
completed in 2004, estimated total nuclear decommissioning costs, including the cost to decommission plant components not subject to radioactive contamination, of approximately $2.3 billion in 2003 dollars.

Duke Energy filed these site-specific nuclear decommissioning cost studies with the NCUC and the PSCSC in conjunction with the various rate
case filings. In addition to the decommissioning cost studies, a new funding study was completed and indicates the current annual funding requirement of approximately $48 million is sufficient to cover the estimated decommissioning costs. Duke
Energy received an order from the NCUC on its rate case filing on December 7, 2009, and the PSCSC accepted a settlement agreement on Duke Energys rate case on January 20, 2010. Both the NCUC and the PSCSC approved the existing $48
million annual funding level for nuclear decommissioning costs.

The operating licenses for Duke Energys nuclear units
are subject to extension. In December 2003, Duke Energy was granted renewed operating licenses for Catawba Nuclear Station Units 1 and 2 until 2043 and McGuire Nuclear Station Unit 1 and 2 until 2041 and 2043, respectively. In 2000, Duke Energy was
granted a renewed operating license for the Oconee Nuclear Station Units 1 and 2 until 2033 and Unit 3 until 2034.

8. Risk Management, Derivative Instruments and Hedging Activities

The primary risks Duke Energy Carolinas manages by utilizing derivative instruments are commodity price risk and interest rate risk. Duke
Energy Carolinas closely monitors the risks associated with commodity price changes and changes in interest rates on its operations and, where appropriate, uses various commodity and interest rate instruments to manage these risks. Certain of these
derivative instruments qualify for hedge accounting and are designated as hedging instruments, while others either do not qualify as a hedge or have not been designated as hedges by Duke Energy Carolinas (hereinafter referred to as undesignated
contracts). Duke Energy Carolinas primary use of energy commodity derivatives is to hedge its generation portfolio against exposure to changes in the price of power. Interest rate swaps may be entered into to manage interest rate risk
associated with Duke Energy Carolinas variable-rate and fixed-rate borrowings.

The accounting guidance for derivatives
requires the recognition of all derivative instruments not identified as normal purchase/normal sale (NPNS) as either assets or liabilities at fair value in the Consolidated Balance Sheets. For derivatives instruments that qualify for hedge
accounting, Duke Energy Carolinas may elect to designate such derivatives as either cash flow hedges or fair value hedges. However, as substantially all of Duke Energy Carolinas operations meet the criteria for regulatory accounting treatment,
Duke Energy Carolinas elects to apply hedge accounting for qualifying contracts on a limited basis since gains and losses associated with the vast majority of derivative contracts, regardless of designation as a hedge or an undesignated contract,
are deferred as regulatory liabilities and assets, respectively. Thus, there is no immediate earnings impact associated with the change in fair values of any such derivative contracts.

Commodity Price Risk

Duke Energy Carolinas is exposed
to the impact of market changes in the future prices of electricity (energy and capacity), coal, natural gas and emission allowances (SO2, seasonal NOXand annual NOX) as a result of its energy operations in electric generation. With respect to commodity price risks associated with
electric generation, Duke Energy Carolinas is exposed to changes including, but not limited to, the cost of coal used to generate electricity, the prices of electricity in wholesale markets and the cost of emission allowances for SO2, seasonal NOXand annual NOX, primarily at Duke Energy Carolinas coal fired power plants. Duke Energy Carolinas closely monitors the risks
associated with commodity price changes on its future operations and, where appropriate, uses various commodity contracts to mitigate the effect of such fluctuations on operations. Duke Energy Carolinas exposure to commodity price risk is
influenced by a number of factors, including, but not limited to, the term of the contract, the liquidity of the market and delivery location.

Commodity derivatives associated with the risk management of Duke Energy Carolinas energy operations are accounted for as undesignated contracts because Duke Energy Carolinas is able to defer gains
or losses on the balance sheet as regulatory liabilities or assets under regulatory accounting treatment. Additionally, Duke Energy Carolinas enters into various contracts that qualify for the NPNS exception. Duke Energy Carolinas primarily applies
the NPNS exception to contracts that relate to the physical delivery of electricity over the next two years.

Commodity
Fair Value Hedges.At December 31, 2009, Duke Energy Carolinas did not have any open commodity derivative instruments that were designated as fair value hedges.

Commodity Cash Flow Hedges. At December 31, 2009, Duke Energy Carolinas did not have any open commodity derivative instruments that were designated as cash flow hedges.

Undesignated Contracts. Duke Energy Carolinas uses derivative contracts as economic hedges to manage the market risk exposures that
arise from electric generation. Undesignated contracts include contracts not designated as a hedge, contracts that do not qualify for hedge accounting, derivatives that no longer qualify for the NPNS scope exception, and de-designated hedge
contracts that were not re-designated as a hedge. At December 31, 2009, Duke Energy Carolinas had an insignificant amount on the Consolidated Balance Sheets related to commodity derivatives in this category.

Interest Rate Risk

Duke
Energy Carolinas is exposed to risk resulting from changes in interest rates as a result of its issuance or anticipated issuance of variable and fixed-rate debt. Duke Energy Carolinas manages its interest rate exposure by limiting its variable-rate
exposures to a percentage of total capitalization and by monitoring the effects of market changes in interest rates. To manage risk associated with changes in interest rates, Duke Energy Carolinas may enter into financial contracts; primarily
interest rate swaps and U.S. Treasury lock agreements. At December 31, 2009, Duke Energy Carolinas had one open interest rate swap which is accounted for as a fair value hedge.



Additionally, in anticipation of certain fixed-rate debt
issuances, Duke Energy Carolinas has executed forward starting interest rate swaps to lock in components of the market interest rates at the time of the debt issuance and terminated these hedges prior to the issuance of the corresponding debt. When
these transactions occurred, the pre-tax gain or loss recognized from inception to termination of the hedges was recorded as a component of Accumulated Other Comprehensive Loss and is being amortized as a component of interest expense over the life
of the debt. See also Note 13.

Volumes

The following table shows information relating to the volume of Duke Energy Carolinas derivative activity outstanding as of December 31, 2009. Amounts disclosed represent the notional dollar
amounts of debt subject to derivative contracts accounted for at fair value in accordance with accounting guidance for derivatives. Volumes associated with contracts qualifying for the NPNS exception have been excluded from the table below. Amounts
disclosed represent the absolute value of notional amounts. Duke Energy Carolinas has netted contractual amounts where offsetting purchase and sale contracts exist with identical delivery locations and time of delivery.

Cash Flow HedgesLocation and Amount of Pre-Tax
Losses Recognized in Comprehensive Income

For the year ended December 31, 2009, approximately $5 million of pre-tax
losses on interest rate hedges were reclassified out of Accumulated Other Comprehensive Loss into earnings. As of December 31, 2009, approximately $5 million of pre-tax deferred net losses on derivative instruments related to terminated forward
starting interest rate hedges accumulated on the Consolidated Balance Sheets in Accumulated Other Comprehensive Loss are expected to be recognized in earnings during the next 12 months as the hedged transactions occur.

Undesignated HedgesLocation and Amount of Pre-Tax Losses Recognized as Regulatory Liabilities

For the year ended December 31, 2009, an insignificant amount of pre-tax losses were recorded in the Consolidated Balance Sheets as a
reduction to Regulatory Liabilities.

See Note 9 for additional information on fair value disclosures related to derivatives.

Credit Risk

Duke Energy Carolinas is exposed to credit risk associated with its sales of power in the retail and wholesale markets, as well as certain other of its business activities. Credit risk for retail sales is monitored and managed through
established policies and procedures in accordance with applicable rules and regulations in its retail jurisdictions.

wholesale market transactions associated with its marketing and risk management operations, Duke Energy Carolinas industry has historically operated under negotiated credit lines. Duke Energy Carolinas uses master collateral agreements to
mitigate credit exposures related to these activities. Duke Energy Carolinas analyzes the counterparties financial condition prior to entering into an agreement, establishes credit limits, and monitors the appropriateness of those limits on an
ongoing basis.



The collateral agreements generally
provide for a counterparty to post cash or letters of credit to the exposed party for exposure in excess of an established threshold. The threshold amount represents an unsecured credit limit, determined in accordance with the corporate credit
policy. Collateral agreements also provide that the inability to post collateral is sufficient cause to terminate contracts and liquidate all positions.

Collateral amounts held or posted may be fixed or may vary depending on the terms of the collateral agreement and the nature of the underlying exposure and generally cover marketing, normal purchases and
normal sales and hedging contracts outstanding. Duke Energy Carolinas may be required to return certain held collateral and post additional collateral should price movements adversely impact the value of open contracts or positions. In many cases,
Duke Energy Carolinas and its counterparties publicly disclosed credit ratings impact the amounts of additional collateral to be posted. If Duke Energy Carolinas were to have a credit rating downgrade, it could result in reductions in
Duke Energy Carolinas unsecured thresholds granted by counterparties. Likewise, downgrades in credit ratings of counterparties could require counterparties to post additional collateral to Duke Energy Carolinas.

Where material credit exposures are identified in connection with other business activities, Duke Energy Carolinas analyzes the financial
condition of its counterparties, customers, or suppliers prior to entering into transactions. Duke Energy Carolinas seeks to mitigate such credit exposures through contractual terms, and may obtain cash, letters of credit, or other credit support
outside of collateral

agreements, where appropriate, based on its financial analysis of the customer and the regulatory or contractual terms and conditions applicable to each transaction.

9. Fair Value of Financial Assets and Liabilities

On January 1, 2008, Duke Energy Carolinas adopted the new fair value disclosure requirements for financial instruments and non-financial derivatives. On January 1, 2009, Duke Energy Carolinas
adopted the new fair value disclosure requirements for non-financial assets and liabilities measured at fair value on a non-recurring basis. Duke Energy Carolinas did not record any cumulative effect adjustment to retained earnings as a result of
the adoption of the new fair value standards.

The accounting guidance for fair value defines fair value, establishes a
framework for measuring fair value in GAAP in the U.S. and expands disclosure requirements about fair value measurements. Under the accounting guidance for fair value, fair value is considered to be the exchange price in an orderly transaction
between market participants to sell an asset or transfer a liability at the measurement date. The fair value definition focuses on an exit price, which is the price that would be received by Duke Energy Carolinas to sell an asset or paid to transfer
a liability, versus an entry price, which would be the price paid to acquire an asset or received to assume a liability. Although the accounting guidance for fair value does not require additional fair value measurements, it applies to other
accounting pronouncements that require or permit fair value measurements.

Duke Energy Carolinas classifies recurring and
non-recurring fair value measurements based on the following fair value hierarchy, as prescribed by the accounting guidance for fair value, which prioritizes the inputs to valuation techniques used to measure fair value into three levels:

Level 1unadjusted quoted prices in active markets for identical assets or liabilities that Duke Energy Carolinas
has the ability to access. An active market for the asset or liability is one in which transactions for the asset or liability occurs with sufficient frequency and volume to provide ongoing pricing information. Duke Energy Carolinas does not adjust
quoted market prices on Level 1 for any blockage factor.

Level 2 a fair value measurement utilizing inputs other
than a quoted market price that are observable, either directly or indirectly, for the asset or liability. Level 2 inputs include, but are not limited to, quoted prices for similar assets or liabilities in an active market, quoted prices for
identical or similar assets or liabilities in markets that are not active and inputs other than quoted market prices that are observable for the asset or liability, such as interest rate curves and yield curves observable at commonly quoted
intervals, volatilities, credit risk and default rates. A level 2 measurement cannot have more than an insignificant portion of the valuation based on unobservable inputs.

Level 3 any fair value measurements which include unobservable inputs for the asset or liability for more than an insignificant portion of the valuation. A level 3 measurement may be based
primarily on level 2 inputs.

The fair value accounting guidance for financial instruments, which was effective for Duke
Energy Carolinas as of January 1, 2008, permits entities to elect to measure many financial instruments and certain other items at fair value that are not required to be accounted for at fair value under existing GAAP. Duke Energy Carolinas
does not currently have any financial assets or financial liabilities that are not required to be accounted for at fair value under GAAP for which it elected to use the option to record at fair value. However, in the future, Duke Energy Carolinas
may elect to measure certain financial instruments at fair value in accordance with this accounting guidance.

The following
tables provide the fair value measurement amounts for assets and liabilities recorded on Duke Energy Carolinas Consolidated Balance Sheets at fair value at December 31, 2009 and 2008:

Valuation methods of the primary fair value measurements disclosed above are as follows:

Investments in equity securities: Investments in equity securities held in the NDTF are typically valued at the closing price in the
principal active market as of the last business day of the quarter. Principal active markets for equity prices include published exchanges such as NASDAQ and NYSE. Foreign equity prices are translated from their trading currency using the currency
exchange rate in effect at the close of the principal active market. Duke Energy Carolinas has not adjusted prices to reflect for after-hours market activity. The majority of Duke Energy Carolinas investments in equity securities are valued
using Level 1 measurements.



Investments in
available-for-sale auction rate securities: At December 31, 2009 and 2008, Duke Energy Carolinas has approximately $82 million par value (approximately $66 million fair value) and approximately $82 million par value (approximately $72
million fair value), respectively, of auction rate securities for which an active market does not currently exist. The majority of these auction rate securities are AAA rated student loan securities for which substantially all the values are
ultimately backed by the U.S. government. All of these securities were valued as of December 31, 2009 and 2008 using measurements appropriate for Level 3 investments. The methods and significant assumptions used to determine the fair values of
Duke Energy Carolinas investment in auction rate debt securities represented a combination of broker-provided quotations and estimations of fair value using validation of such quotations through internal discounted cash flow models which
incorporated primarily Duke Energy Carolinas own assumptions as to the term over which such investments will be recovered at par, the current level of interest rates, and the appropriate risk-adjusted (for liquidity and credit) discount rates
when relevant

observable inputs are not available to determine present value of such cash flows. In preparing the valuations, all significant value drivers were considered, including the underlying collateral.

See Note 10 for additional information on Duke Energy Carolinas investments in auction rate securities.

Investments in debt securities: Most debt investments held in the NDTF are valued based on a calculation using interest rate curves
and credit spreads applied to the terms of the debt instrument (maturity and coupon interest rate) and consider the counterparty credit rating. Most debt valuations are Level 2 measures. If the market for a particular fixed income security is
relatively inactive or illiquid, the measurement is a Level 3 measurement. U.S. Treasury debt is typically a Level 1 measurement.

Commodity derivatives: The pricing for commodity derivatives is primarily a calculated value which incorporates the forward price and is adjusted for liquidity (bid-ask spread), credit or non-performance risk (after reflecting credit
enhancements such as collateral) and discounted to present value. The primary difference between a Level 2 and a Level 3 measurement has to do with the level of activity in forward markets for the commodity. If the market is relatively inactive, the
measurement is deemed to be a Level 3 measurement.

Additional Fair Value Disclosures: The fair value of financial
instruments, excluding financial assets and certain financial liabilities included in the scope of the accounting guidance for fair value measurements disclosed in the tables above, is summarized in the following table. Judgment is required in
interpreting market data to develop the estimates of fair value.

The fair value of
cash and cash equivalents, accounts and notes receivable and accounts payable are not materially different from their carrying amounts because of the short-term nature of these instruments and/or because the stated rates approximate market rates.

10. Investments in Debt and Equity Securities

Duke Energy Carolinas classifies its investments in debt and equity securities as available-for-sale, which are reported at fair value on the Consolidated Balance Sheets with unrealized gains and losses
excluded from earnings and reported either as a regulatory asset or liability, as discussed further below, or as a component of other comprehensive income until realized.

Duke Energy Carolinas available-for-sale securities are comprised of investments held in the NDTF and investments in auction rate debt securities. The investments within the NDTF are managed by
independent investment managers with discretion to buy, sell and invest pursuant to the objectives set forth by the trust agreements. Therefore, Duke Energy Carolinas has limited oversight of the day-to-day management of these investments. Since
day-to-day investment decisions, including buy and sell decisions, are made by the investment manager, the ability to hold investments in unrealized loss positions is outside the control of Duke Energy Carolinas. Accordingly, all unrealized losses
associated with equity securities within the NDTF are considered other-than-temporary and are recognized immediately when the fair value of individual investments is less than the cost basis of the investment. Pursuant to regulatory accounting,
substantially all unrealized losses associated with investments in debt and equity securities within the NDTF are deferred as a regulatory asset, thus there is no immediate impact on the earnings of Duke Energy Carolinas as a result of any
other-than-temporary impairments that would otherwise be required to be recognized in earnings. For investments in auction rate debt securities, unrealized gains and losses are included in other comprehensive income until realized, unless it is
determined that the carrying value of an investment is other-than-temporarily impaired, at which time the write-down to fair value may be included in earnings based on the criteria discussed below.



With respect to investments in debt securities, during the first
quarter of 2009, Duke Energy Carolinas adopted the modified other-than-temporary impairment accounting guidance issued by the FASB, which changed the other-than-temporary impairment guidance related to investments in debt securities. Under this
modified other-than-temporary impairment guidance, if the entity does not have an intent to sell the security and it is not more likely than not that management will be required to sell the debt security before the recovery of its cost basis, the
impairment write-down to fair value would be recorded as a component of other comprehensive income, except for when it is determined that a credit loss exists. In determining whether a credit loss exists, management considers, among other things,
the length of time and the extent to which the fair value has been less than the amortized cost basis, changes in the financial condition of the issuer of the security, or in the case of an asset backed security, the financial condition of the
underlying loan obligors, consideration of underlying collateral and guarantees of amounts by government entities, ability of the issuer of the security to make scheduled interest or principal payments and any changes to the rating of the security
by rating agencies. If it is determined that a credit loss exists, the amount of impairment write-down to fair value would be split between the credit loss, which would be recognized in earnings, and the amount attributable to all other factors,
which would be recognized in other comprehensive income. The adoption of this modified other-than-temporary impairment guidance primarily impacts Duke Energys Carolinas investments in auction rate debt securities since, as discussed above, the
debt securities held in the NDTF receive regulatory deferral treatment of all unrealized losses including other-than-temporary impairments. Since management believes, based on consideration of the criteria above, that no credit loss exists as of
December 31, 2009 and management does not have the intent to sell its investments in auction rate debt securities, and it is not more likely than not that management will be required to sell these securities before the anticipated recovery of
their cost basis, management concluded that there were no other-than-temporary impairments necessary as of December 31, 2009 and 2008. Accordingly, all changes in the market value of investments in auction rate debt securities were reflected as
a component of other comprehensive income in 2009 and 2008. See Note 9 for additional information related to fair value measurements for investments in auction rate debt securities.

Management will continue to monitor the carrying value of its entire portfolio of investments in the future to determine if any
other-than-temporary impairment losses should be recognized.

Investments in debt and equity securities are classified as either short-term
investments or long-term investments based on managements intent and ability to sell these securities, taking into consideration illiquidity factors in the current markets with respect to certain short-term investments that have historically
provided for a high degree of liquidity, such as investments in auction rate debt securities.

Short-term investments.
At December 31, 2008, Duke Energy Carolinas had approximately $46 million carrying value (approximately $49 million par value) of investments in auction rate debt securities classified as short-term investments as Duke Energy Carolinas believed
the investments were reasonably expected to be refunded within the next 12 months based on notification of a refunding plan by the issuer. However, due to an ongoing delay in the refunding plan, Duke Energy Carolinas reclassified these securities to
long-term investments, included in Other within Investments and Other Assets, in the second quarter of 2009. Duke Energy Carolinas continues to hold these securities at December 31, 2009. The remaining balance of investments in auction rate
debt securities at December 31, 2008 were included in long-term investments and are discussed below. During the year ended December 31, 2009, there were no purchases or sales of short-term investments. During the years ended
December 31, 2008 and 2007, Duke Energy Carolinas purchased short-term investments of approximately $3,161 million and $6,779 million, respectively, and received proceeds on sales of approximately $3,079 million and $6,946 million,
respectively.

Other long-term investments. Duke Energy Carolinas classifies its investments in debt and equity
securities held in the NDTF as long-term. Additionally, approximately $66 million carrying value (approximately $82 million par value) and approximately $26 million carrying value (approximately $33 million par value) of investments in auction rate
debt securities have been classified as long-term at December 31, 2009 and December 31, 2008, respectively, due to market illiquidity factors as a result of continued failed auctions. All of these investments are classified as
available-for-sale and, therefore, are reflected on the Consolidated Balance Sheets at estimated fair value based on either quoted market prices or managements best estimate of fair value based on expected future cash flow using appropriate
risk-adjusted discount rates. Since management does not intend to use these investments in current operations, these investments are classified as long-term. At December 31, 2009 and 2008, Duke Energy Carolinas long-term
available-for-sale investments had a fair market value of approximately $1,831 million and $1,462 million, respectively.

The
cost of securities sold is determined using the specific identification method. During the years ended December 31, 2009, 2008 and 2007, Duke Energy Carolinas purchased long-term investments of approximately $2,118 million, $2,188 million
and $1,276 million, respectively, and received proceeds on sales of approximately $2,094 million, $2,140 million and $1,228 million, respectively. All of these purchases and sales relate to activity within the NDTF, including annual contributions to
the NDTF of approximately $48 million pursuant to an order by the NCUC (see Note 7).

The estimated fair values of short-term
and long-term investments classified as available-for-sale are as follows (in millions):

For the years ended December 31, 2009, 2008 and 2007, there were no gains reclassified out of AOCI into earnings.

Debt securities held, which includes auction rate securities based on the stated maturity date, at December 31, 2009, mature as
follows: $33 million in less than one year, $107 million in one to five years, $121 million in six to ten years and $408 million thereafter.



The fair values and gross unrealized losses of available-for-sale equity and debt securities which are in an unrealized loss position for
which other-than-temporary impairment losses have not been recorded, summarized by investment type and length of time that the securities have been in a continuous loss position, are presented in the table below as of December 31, 2009 and
2008:

First Mortgage Bonds.In November 2009, Duke Energy Carolinas issued $750 million principal amount of first mortgage bonds, which
carry a fixed interest rate of 5.30% and mature February 15, 2040. Proceeds from this issuance will be used to fund capital expenditures and general corporate purposes, including the repayment at maturity of $500 million of senior notes and
first mortgage bonds in the first half of 2010.

In November 2008, Duke Energy Carolinas issued $900 million
principal amount of first mortgage bonds, of which $500 million carry a fixed interest rate of 7.00% and mature November 15, 2018 and $400 million carry a fixed interest rate of 5.75% and mature November 15, 2013. The net proceeds from
issuance were used to repay amounts borrowed under the master credit facility, to repay senior notes due January 1, 2009, to replenish cash used to repay senior notes at their scheduled maturity in October 2008 and for general corporate
purposes.

In April 2008, Duke Energy Carolinas issued $900 million principal amount of first mortgage bonds, of which $300
million carry a fixed interest rate of 5.10% and mature April 15, 2018 and $600 million carry a fixed interest rate of 6.05% and mature April 15, 2038. Proceeds from the issuance were used to fund capital expenditures and for general
corporate purposes. In anticipation of this debt issuance, Duke Energy Carolinas executed a series of interest rate swaps in 2007 to lock in the market interest rates at that time. The value of these interest rate swaps, which were terminated prior
to issuance of the fixed rate debt, was a pre-tax loss of approximately $23 million. This amount was recorded as a component of Accumulated Other Comprehensive Loss and is being amortized as a component of Interest Expense over the life of the debt.

In January 2008, Duke Energy Carolinas issued $900 million principal amount of first mortgage bonds, of which $400 million
carry a fixed interest rate of 5.25% and mature January 15, 2018 and $500 million carry a fixed interest rate of 6.00% and mature January 15, 2038. Proceeds from the issuance were used to fund capital expenditures and for general corporate
purposes, including the repayment of commercial paper. In anticipation of this debt issuance, Duke Energy Carolinas executed a series of interest rate swaps in 2007 to lock in the market interest rates at that time. The value of these interest rate
swaps, which were terminated prior to issuance of the fixed rate debt, was a pre-tax loss of approximately $18 million. This amount was recorded as a component of Accumulated Other Comprehensive Loss and is being amortized as a component of Interest
Expense over the life of the debt.

Other Debt.In September 2009, Duke Energy Carolinas converted $77 million of
tax-exempt variable-rate demand bonds to tax-exempt term bonds, which carry a fixed interest rate of 3.60% and mature February 1, 2017. In connection with the conversion, the tax-exempt bonds were secured by a series of Duke Energy
Carolinas first mortgage bonds.

In April 2008, Duke Energy Carolinas refunded $100 million of tax-exempt auction rate
bonds through the issuance of $100 million of tax-exempt variable-rate demand bonds, which are supported by a direct-pay letter of credit. The variable-rate demand bonds, which are due November 1, 2040, had an initial interest rate of 2.15%
which will be reset on a weekly basis.

Convertible Senior Notes.In May 2003, Duke Energy issued approximately $770
million of 1.75% convertible senior notes that were convertible into Duke Energy common stock at a premium of 40% above the May 1, 2003 closing common stock market price of $16.85 per share. The conversion of these senior notes into shares of
Duke Energy common stock was contingent upon the occurrence of certain events during specified periods. During 2006, Duke Energy issued shares of common stock to settle a portion of the convertible senior notes. In May 2007, pursuant to the terms of
the debt agreement, substantially all of the holders of the Duke Energy convertible senior notes required Duke Energy to repurchase the then outstanding balance of approximately $110 million at a price equal to 100% of the principal amount plus
accrued interest.

Money Pool. Beginning in October 2008, Duke Energy Carolinas receives support for its short-term
borrowing needs through its participation with Duke Energy and other Duke Energy subsidiaries in a money pool arrangement. Under this arrangement, those companies with short-term funds may provide short-term loans to affiliates participating under
this arrangement. The money pool is structured such that

DUKE ENERGY CAROLINAS, LLC

Notes To Consolidated Financial
Statements(Continued)



Duke Energy Carolinas separately manages its cash needs and working capital requirements. Accordingly, there is no net settlement of receivables and payables between Duke Energy Carolinas and
other money pool participants. Participation in the money pool arrangement replaced Duke Energy Carolinas commercial paper program, which was terminated effective September 30, 2008. In connection with the termination of the commercial
paper program, Duke Energy Carolinas repaid the approximately $300 million outstanding commercial paper balance and borrowed approximately $300 million via the money pool on a long-term basis, as discussed below. As of December 31, 2009 and
December 31, 2008, Duke Energy Carolinas had net short-term money pool receivables of approximately $589 million and $338 million, respectively, which are classified within Receivables in the accompanying Consolidated Balance Sheets. The $251
million increase in the money pool receivable for the year ended December 31, 2009 is reflected as a cash outflow in Notes due from affiliate, net within Net cash used in investing activities on the Consolidated Statements of Cash Flows. At
both December 31, 2009 and December 31, 2008, approximately $300 million of Duke Energy Carolinas money pool borrowings were classified as long-term borrowings within Long-Term Debt in the accompanying Consolidated Balance Sheets.

Accounts Receivable Securitization. Duke Energy Carolinas securitizes certain accounts receivable through Duke
Energy Receivables Finance Company, LLC (DERF), a bankruptcy remote, special purpose subsidiary. DERF is a wholly-owned limited liability company with a separate legal existence from its parent, and its assets are not intended to be generally
available to creditors of Duke Energy Carolinas. As a result of the securitization, on a daily basis Duke Energy Carolinas sells certain accounts receivable, arising from the sale of electricity and/or related services as part of Duke Energy
Carolinas franchised electric business, to DERF. In order to fund its purchases of accounts receivable, DERF has a $300 million secured credit facility with a commercial paper conduit administered by Citibank, N.A., which terminates in
September 2011. The credit facility and related securitization documentation contain several covenants, including covenants with respect to the accounts receivable held by DERF, as well as a covenant requiring that the ratio of Duke Energy Carolinas
consolidated indebtedness to Duke Energy Carolinas consolidated capitalization not exceed 65%. As of December 31, 2009 and 2008, the interest rate associated with the credit facility, which is based on commercial paper rates, was 1.6% and 4.7%,
respectively, and $300 million was outstanding under the credit facility as of both December 31, 2009 and 2008. The securitization transaction was not structured to meet the criteria for sale accounting treatment under the accounting guidance
for transfers and servicing of financial assets and, accordingly, is reflected as a secured borrowing in the Consolidated Balance Sheets. As of December 31, 2009 and 2008, the $300 million outstanding balance of the credit facility was secured
by approximately $556 million and $518 million, respectively, of accounts receivable held by DERF. The obligations of DERF under the credit facility are non-recourse to Duke Energy Carolinas. DERF meets the accounting definition of a VIE and is
subject to the new accounting rules for consolidation and transfers of financial assets effective January 1, 2010 discussed in Note 1; however, the new accounting rules will not result in a substantial change to the accounting treatment for
DERF.

Floating Rate Debt. Unsecured debt, secured debt and other debt included approximately $795 million and $1,022
million of floating-rate debt as of December 31, 2009, and 2008, respectively. Floating-rate debt is primarily based on commercial paper rates or a spread relative to an index such as a London Interbank Offered Rate. As of December 31,
2009 and 2008, the average interest rate associated with floating-rate debt was approximately 0.9% and 3.0%, respectively.

Duke Energy Carolinas has the ability under certain
debt facilities to call and repay the obligation prior to its scheduled maturity. Therefore, the actual timing of future cash repayments could be materially different than the above as a result of Duke Energy Carolinas ability to repay these
obligations prior to their scheduled maturity.



Duke
Energy Carolinas may be required to repay certain debt should the credit ratings at Duke Energy Carolinas fall to a certain level at Standard & Poors (S&P) or Moodys Investors Service (Moodys). As of December 31,
2009, Duke Energy Carolinas had $6 million of senior unsecured notes which mature serially through 2012 that may be required to be repaid if Duke Energy Carolinas senior unsecured debt ratings fall below BBB- at S&P or Baa3 at
Moodys, and $16 million of senior unsecured notes which mature serially through 2016 that may be required to be repaid if Duke Energy Carolinas senior unsecured debt ratings fall below BBB at S&P or Baa2 at Moodys. As of
February 1, 2010, Duke Energy Carolinas senior unsecured credit rating was A- at S&P and A3 at Moodys.

Available Credit Facilities.The total capacity under Duke Energys master credit facility, which expires in June 2012, is approximately $3.14 billion. The credit facility contains an option allowing borrowing up to the full
amount of the facility on the day of initial expiration for up to one year. Duke Energy and certain of its wholly-owned subsidiaries, including Duke Energy Carolinas, each have borrowing capacity under the master credit facility up to specified sub
limits for each borrower. However, Duke Energy has the unilateral ability to increase or decrease the borrowing sub limits of each borrower, subject to per borrower maximum cap limitations, at any time. At December 31, 2009, Duke Energy
Carolinas borrowing sub limit under this master credit facility was $840 million. The amount available to Duke Energy Carolinas under the sub limits to Duke Energys master credit facility has been reduced by borrowings through the money
pool arrangement, and the use of the master credit facility to backstop the issuances of letters of credit and certain tax-exempt bonds.

In September 2008, Duke Energy and certain of its wholly-owned subsidiaries, including Duke Energy Carolinas, borrowed a total of approximately $1 billion under Duke Energys master credit facility.
Duke Energy Carolinas proportionate share of the borrowing was approximately $260 million, which was repaid from the proceeds received from a November 2008 debt issuance discussed above.

At December 31, 2009 and December 31, 2008, approximately $195 million and $422 million, respectively, of tax-exempt bonds, and
approximately $300 million of money pool borrowings at both December 31, 2009 and 2008, both of which are short-term obligations by nature, were classified as Long-Term Debt on the Consolidated Balance Sheets due to Duke Energy Carolinas
intent and ability to utilize such borrowings as long-term financing. Duke Energy and Duke Energy Carolinas credit facilities with non-cancelable terms in excess of

one year as of the balance sheet date give Duke Energy Carolinas the ability to refinance these short-term obligations on a long-term basis. The master credit facility served as a backstop for
the $195 million of pollution control bonds outstanding at December 31, 2009 (of which approximately $100 million is in the form of letters of credit).

Restrictive Debt Covenants.Duke Energys credit agreements contain various financial and other covenants, including, but not limited to, a covenant regarding the debt-to-total capitalization
ratio at Duke Energy Carolinas to not exceed 65%. Additionally, Duke Energy Carolinas debt and credit agreements contain various financial and other covenants. Failure to meet those covenants beyond applicable grace periods could result in
accelerated due dates and/or termination of the agreements. As of December 31, 2009, Duke Energy and Duke Energy Carolinas were in compliance with all covenants that would impact Duke Energy Carolinas ability to borrow funds under its
debt and credit facilities. In addition, some credit agreements may allow for acceleration of payments or termination of the agreements due to nonpayment, or the acceleration of other significant indebtedness of the borrower or some of its
subsidiaries. None of the debt or credit agreements contain material adverse change clauses.

Other Matters. In
October 2007, Duke Energy filed a registration statement (Form S-3) with the SEC. Under this Form S-3, which is uncapped, Duke Energy and certain subsidiaries, including Duke Energy Carolinas, may issue debt through October 2010 at amounts, prices
and with terms to be determined at the time of such offerings.

At December 31, 2009, approximately $2.4 billion of debt
issued by Duke Energy Carolinas was guaranteed by Duke Energy.

14. Commitments and Contingencies

General Insurance

Duke
Energy Carolinas carries insurance and reinsurance coverages either directly or through Duke Energys current (and Duke Energy Carolinas former) captive insurance company, Bison, and its affiliates, consistent with companies engaged in
similar commercial operations with similar type properties. Duke Energy Carolinas insurance coverage includes (i) commercial general public liability insurance for liabilities arising to third parties for bodily injury and property damage
resulting from Duke Energy Carolinas operations; (ii) workers compensation liability coverage to required statutory limits; (iii) automobile liability insurance for all owned, non-owned and hired vehicles covering liabilities
to third parties for bodily injury and property damage; (iv) insurance policies in support of the indemnification provisions of Duke Energy Carolinas by-laws and (v) property insurance covering the replacement value of all real and
personal property damage, excluding electric transmission and distribution lines, including damages arising from boiler and machinery breakdowns, earthquake, flood damage and extra expense. All coverage is subject to certain deductibles or
retentions, sublimits, terms and conditions common for companies with similar types of operations.

Duke Energy Carolinas also
maintains excess liability insurance coverage above the established primary limits for commercial general liability and automobile liability insurance. Limits, terms, conditions and deductibles are comparable to those carried by other energy
companies of similar size.

The cost of Duke Energy Carolinas general insurance coverage can fluctuate year to year
reflecting the changing conditions of the insurance markets.

Nuclear Insurance

Duke Energy Carolinas owns and operates the McGuire and Oconee Nuclear Stations and operates and has a partial ownership interest in the
Catawba Nuclear Station. The McGuire and Catawba Nuclear Stations have two nuclear reactors each and Oconee has three. Nuclear insurance includes: nuclear liability coverage; property, decontamination and premature decommissioning coverage; and
business interruption and/or extra expense coverage. The other joint owners of the Catawba Nuclear Station reimburse Duke Energy for certain expenses associated with nuclear insurance premiums. The Price-Anderson Act requires Duke Energy Carolinas
to provide for public liability claims resulting from nuclear incidents to the maximum total financial protection liability, which was approximately $12.5 billion and increased to approximately $12.6 billion effective January 1, 2010.

Primary Liability Insurance. Duke Energy Carolinas has purchased the maximum reasonably available private primary
liability insurance as required by law, which was $300 million and increased to $375 million effective January 1, 2010.



Excess Liability Program. This program provides approximately $12.2 billion of coverage through the Price-Anderson Acts
mandatory industry-wide excess secondary financial protection program of risk pooling. The $12.2 billion is the sum of the current potential cumulative retrospective premium assessments of $117.5 million per licensed commercial nuclear reactor. This
would be increased by $117.5 million for each additional commercial nuclear reactor licensed, or reduced by $117.5 million for nuclear reactors no longer operational and may be exempted from the risk pooling program. Under this program, licensees
could be assessed retrospective premiums to compensate for public liability damages in the event of a nuclear incident at any licensed facility in the U.S. If such an incident should occur and public liability damages exceed primary liability
insurance, licensees may be assessed up to $117.5 million for each of their licensed reactors, payable at a rate not to exceed $17.5 million a year per licensed reactor for each incident. The assessment and rate are subject to indexing for inflation
and may be subject to state premium taxes. The Price-Anderson Act provides for an inflation adjustment at least every five years with the last adjustment effective October 2008.

Duke Energy Carolinas is a member of Nuclear Electric Insurance Limited (NEIL), which provides property and accidental outage insurance
coverage for Duke Energy Carolinas nuclear facilities under three policy programs:

Primary Property Insurance.
This policy provides $500 million of primary property damage coverage for each of Duke Energy Carolinas nuclear facilities.

Excess Property Insurance. This policy provides excess property, decontamination and decommissioning liability insurance: $2.25 billion for the Catawba Nuclear Station and $1.0 billion each for the Oconee and McGuire Nuclear
Stations. The Oconee and McGuire Nuclear Stations also share an additional $1.0 billion insurance limit above this excess. This shared limit is not subject to reinstatement in the event of a loss.

Accidental Outage Insurance. This policy provides business interruption and/or extra expense coverage resulting from an accidental
outage of a nuclear unit. Each McGuire and Catawba unit is insured for up to $3.5 million per week, and the Oconee units are insured for up to $2.8 million per week. Coverage amounts decline if more than one unit is involved in an accidental outage.
Initial coverage begins after a 12-week deductible period for Catawba and a 26-week deductible period for McGuire and Oconee and continues at 100% for 52 weeks and 80% for the next 110 weeks. The McGuire and Catawba policy limit is $490 million and
the Oconee policy limit is $392 million.

In the event of large industry losses, NEILs Board of Directors may assess
Duke Energy Carolinas for amounts up to ten times its annual premiums. The current potential maximum assessments are: Primary Property Insurance$37 million, Excess Property Insurance$43 million and Accidental Outage Insurance$22
million.

Pursuant to regulations of the NRC, each companys property damage insurance
policies provide that all proceeds from such insurance be applied, first, to place the plant in a safe and stable condition after a qualifying accident, and second, to decontaminate before any proceeds can be used for decommissioning, plant repair
or restoration.

In the event of a loss, the amount of insurance available might not be adequate to cover property damage and
other expenses incurred. Uninsured losses and other expenses, to the extent not recovered by other sources, could have a material adverse effect on Duke Energy Carolinas results of operations, cash flows or financial position.

The maximum assessment amounts include 100% of Duke Energy Carolinas potential obligation to NEIL for the Catawba Nuclear Station.
However, the other joint owners of the Catawba Nuclear Station are obligated to assume their pro rata share of liability for retrospective premiums and other premium assessments resulting from the Price-Anderson Acts excess secondary financial
protection program of risk pooling, or the NEIL policies.

Environmental

Duke Energy Carolinas is subject to federal, state and local regulations regarding air and water quality, hazardous and solid waste disposal
and other environmental matters. These regulations can be changed from time to time, imposing new obligations on Duke Energy Carolinas.

Remediation Activities. Duke Energy Carolinas is responsible for environmental remediation at various contaminated sites. These include some properties that are part of ongoing Duke Energy
Carolinas operations, sites formerly owned or used by Duke Energy Carolinas entities, and sites owned by third parties. Remediation typically involves management of contaminated soils and may involve groundwater remediation. Managed in
conjunction with relevant federal, state and local agencies, activities vary with site conditions and locations, remedial requirements, complexity and sharing of responsibility. If remediation activities involve statutory joint and several liability
provisions, strict liability, or cost recovery or contribution actions, Duke Energy Carolinas or its affiliates could potentially be held responsible for contamination caused by other parties. In some instances, Duke Energy Carolinas may share
liability associated with contamination with other potentially responsible parties, and may also benefit from insurance policies or contractual indemnities that cover some or all cleanup costs. All of these sites generally are managed in the normal
course of business or by affiliate operations.

Included in Other within Deferred Credits and Other Liabilities and Other on
the Consolidated Balance Sheets were total accruals related to extended environmental-related activities of approximately $13 million and $15 million as of December 31, 2009 and December 31, 2008, respectively. These accruals represent
Duke Energy Carolinas provisions for costs associated with remediation activities at some of its current and former sites, as well as other relevant environmental contingent liabilities. Management, in the normal course of business,
continually assesses the nature and extent of known or potential environmental-related contingencies and records liabilities when losses become probable and are reasonably estimable. Costs associated with remediation activities within Duke Energy
Carolinas regulated operations are typically expensed unless recovery of the costs is deemed probable.

Clean
Water Act 316(b). The EPA finalized its cooling water intake structures rule in July 2004. The rule established aquatic protection requirements for existing facilities that withdraw 50 million gallons or more of water per day from
rivers, streams, lakes, reservoirs, estuaries, oceans or other U.S. waters for cooling purposes. Eight of Duke Energy Carolinas eleven coal and nuclear-fueled generating facilities in which Duke Energy Carolinas is either a whole or partial
owner are affected sources under that rule. On April 1, 2009, the U.S. Supreme Court ruled in favor of the appellants that the EPA may consider costs when determining which technology option each site should implement. Depending on how the
cost-benefit analysis is incorporated into the revised EPA rule, the analysis could narrow the range of technology options required for each of the eight affected facilities. Because of the wide range of potential outcomes, Duke Energy Carolinas is
unable to estimate its costs to comply at this time.



Clean Air Interstate Rule (CAIR).The EPA finalized its CAIR in May 2005. The CAIR limits total annual and summertime NOxemissions and annual SO2emissions from electric generating facilities across the Eastern U.S. through a two-phased cap-and-trade program. Phase 1
began in 2009 for NOxand begins in 2010 for SO2. Phase 2 begins in 2015 for both NOxand SO2. On March 25, 2008, the U.S. Court of Appeals for the District of Columbia (D.C. Circuit) heard oral argument in a
case involving multiple challenges to the CAIR. On July 11, 2008, the D.C. Circuit issued its decision in North Carolina v. EPANo. 05-1244 vacating the CAIR. The EPA filed a petition for rehearing on September 24, 2008 with
the D.C. District Court asking the court to reconsider various parts of its rule vacating the CAIR. In December 2008, the D.C. Circuit issued a decision remanding the CAIR to the EPA without vacatur. The EPA must now conduct a new rulemaking to
modify the CAIR in accordance with the courts July 11, 2008 opinion. This decision means that the CAIR as initially finalized in 2005 remains in effect until the new EPA rule takes effect. The EPA has indicated that it currently plans on
issuing a proposed rule in April-May 2010 timeframe. It is uncertain how long the current CAIR will remain in effect or how the new rulemaking will alter the CAIR.

The emission controls Duke Energy Carolinas is installing to comply with state specific clean air legislation will contribute significantly to achieving compliance with the CAIR requirements.
Additionally, Duke Energy Carolinas is currently unable to estimate the costs to comply with any new rule the EPA will issue in the future as a result of the D.C. District Courts December 2008 decision discussed above.

Coal Combustion Product (CCP) Management. Duke Energy Carolinas currently estimates that it will spend approximately
$87 million over the period 2010-2014 to install synthetic caps and liners at existing and new CCP landfills and to convert some of its CCP handling systems from wet to dry systems.

The EPA and a number of states are considering additional regulatory measures that will contain specific and more detailed requirements for
the management and disposal of coal combustion products, primarily ash, from Duke Energy Carolinas coal-fired power plants. The EPA has indicated that it intends to propose a rule early in 2010. Additional laws and regulations under
consideration which more stringently regulate coal ash, including the potential regulation of coal ash as hazardous waste, will likely increase costs for Duke Energy Carolinas coal facilities. Duke Energy Carolinas is unable to estimate its
potential costs at this time.

Litigation

New Source Review (NSR). In 1999-2000, the U.S. Department of Justice (DOJ), acting on behalf of the EPA
and joined by various citizen groups and states, filed a number of complaints and notices of violation against multiple utilities across the country for alleged violations of the NSR provisions of the Clean Air Act (CAA). Generally, the government
alleges that projects performed at various coal-fired units were major modifications, as defined in the CAA, and that the utilities violated the CAA when they undertook those projects without obtaining permits and installing the best available
emission controls for SO2, NOxand particulate matter. The complaints seek injunctive relief to require
installation of pollution control technology on various generating units that allegedly violated the CAA, and unspecified civil penalties in amounts of up to $32,500 per day for each violation. A number of Duke Energy Carolinas plants have
been subject to these allegations. Duke Energy Carolinas asserts that there were no CAA violations because the applicable regulations do not require permitting in cases where the projects undertaken are routine or otherwise do not result
in a net increase in emissions.

In 2000, the government brought a lawsuit against Duke Energy Carolinas in the U.S. District
Court in Greensboro, North Carolina. The EPA claims that 29 projects performed at 25 of Duke Energy Carolinas coal-fired units in the Carolinas violate these NSR provisions. Three environmental groups have intervened in the case. In August
2003, the trial court issued a summary judgment opinion adopting Duke Energy

Carolinas legal positions on the standard to be used for measuring an increase in emissions, and granted judgment in favor of Duke Energy Carolinas. The trial courts decision was
appealed and ultimately reversed and remanded for trial by the U.S. Supreme Court. At trial, Duke Energy Carolinas will continue to assert that the projects were routine or not projected to increase emissions. No trial date has been set.

It is not possible to predict with certainty whether Duke Energy Carolinas will incur any liability or to estimate the damages, if any,
that Duke Energy Carolinas might incur in connection with this matter. Ultimate resolution of this matter, even in settlement, could have a material adverse effect on Duke Energy Carolinas consolidated results of operations, cash flows or
financial position. However, Duke Energy Carolinas will pursue appropriate regulatory treatment for any costs incurred in connection with such resolution.

Cliffside Unit 6 Permit.On July 16, 2008, the Southern Alliance for Clean Energy, Environmental Defense Fund, National Parks Conservation Association, Natural Resources Defenses
Council, and Sierra Club (collectively referred to as Citizen Groups) filed suit in federal court alleging that Duke Energy Carolinas violated the CAA when it commenced construction of Cliffside Unit 6 at Cliffside Steam Station in Rutherford
County, North Carolina without obtaining a determination that the MACT emission limits will be met for all prospective hazardous air emissions at that plant. The Citizen Groups claim the right to injunctive relief against further construction at the
plant as well as civil penalties in the amount of up to $32,500 per day for each alleged violation. In July 2008, Duke Energy Carolinas voluntarily performed a MACT assessment of air emission controls planned for Cliffside Unit 6 and submitted the
results to the DENR. On August 8, 2008 the plaintiffs filed a motion for summary judgment. On December 2, 2008, the Court granted summary judgment in favor of the Plaintiffs and entered judgment ordering Duke Energy Carolinas to initiate a
MACT process before the DAQ. The court did not order an injunction against further construction, but retained jurisdiction to monitor the MACT proceedings. On December 4, 2008, Duke Energy Carolinas submitted its MACT filing and supporting
information to the DAQ specifically seeking DAQs concurrence as a threshold matter that construction of Cliffside Unit 6 is not a major source subject to section 112 of the CAA and submitting a MACT determination application. Concurrent with
the initiation of the MACT process, Duke Energy Carolinas filed a notice of appeal to the Fourth Circuit Court of Appeals of the Courts December 2, 2008 order to reverse the Courts determination that Duke Energy Carolinas violated
the CAA. The DAQ issued the revised permit on March 13, 2009, as discussed above. Based upon DAQs minor-source determination, Duke Energy Carolinas filed a motion requesting that the court abstain from further action on the matter and
dismiss the plaintiffs complaint. The court granted Duke Energy Carolinas motion to abstain and dismissed the plaintiffs complaint without prejudice. On August 3, 2009, plaintiffs filed a notice of appeal of the courts order
and Duke Energy Carolinas likewise appealed on the grounds, among others, that the dismissal should have been with prejudice to any future filing.

It is not possible to predict with certainty whether Duke Energy Carolinas will incur any liability or to estimate the damages, if any, that Duke Energy Carolinas might incur in connection with this
matter. To the extent that a court of proper jurisdiction halts construction of the plant, Duke Energy Carolinas will seek to meet customers needs for power through other resources. In addition, Duke Energy Carolinas will seek appropriate
regulatory treatment for the investment in the plant.

Duke Energy Retirement Cash Balance Plan.A class action
lawsuit was filed in federal court in South Carolina against Duke Energy and the Duke Energy Retirement Cash Balance Plan, alleging violations of Employee Retirement Income Security Act (ERISA) and the Age Discrimination in Employment Act
(ADEA). These allegations arise out of the conversion of the Duke Energy Company Employees Retirement Plan into the Duke Energy Retirement Cash Balance Plan. The case also raises some Plan administration issues, alleging errors in
the application of Plan provisions (i.e., the calculation of interest rate credits in 1997 and 1998 and the calculation of lump-sum distributions). The plaintiffs seek to represent present and former participants in the Duke Energy
Retirement Cash Balance Plan. This group is estimated to include approximately 36,000 persons. The plaintiffs also seek to divide the putative class into sub-classes based on age. Six causes of action are alleged, ranging from age discrimination, to
various alleged ERISA violations, to allegations of breach of fiduciary duty. Plaintiffs seek a broad array of remedies, including a retroactive reformation of the Duke Energy Retirement Cash Balance Plan and a recalculation of
participants/ beneficiaries benefits under the revised and reformed plan. Duke Energy filed its answer in March 2006. A portion of this contingent liability was assigned to Spectra Energy in connection with the spin-off in January
2007. A hearing on the plaintiffs motion to amend the complaint to add an additional age discrimination claim, defendants motion to dismiss and the respective motions for summary judgment was held in December 2007. On June 2, 2008,
the court issued its ruling denying plaintiffs motion to add the additional claim and dismissing a number of plaintiffs claims, including the claims for ERISA age discrimination. Since that date, plaintiffs have notified Duke Energy that
they are withdrawing their ADEA claim. On September 4, 2009, the court issued its order certifying classes for three of the remaining claims but not certifying their claims as to plaintiffs fiduciary duty claims. At an unsuccessful
mediation in September 2008, the plaintiffs quantified their claims as being in excess of $150 million. It is not possible to predict with certainty the damages, if any, that Duke Energy might incur in connection with this matter.



Asbestos-related Injuries and Damages Claims. Duke
Energy Carolinas has experienced numerous claims for indemnification and medical cost reimbursement relating to damages for bodily injuries alleged to have arisen from the exposure to or use of asbestos in connection with construction and
maintenance activities conducted by Duke Energy Carolinas on its electric generation plants prior to 1985.

Amounts recognized
as asbestos-related reserves related to Duke Energy Carolinas in the Consolidated Balance Sheets totaled approximately $980 million and $1,031 million as of December 31, 2009 and December 31, 2008, respectively, and are classified in Other
within Deferred Credits and Other Liabilities and Other within Current Liabilities. These reserves are based upon the minimum amount in Duke Energys best estimate of the range of loss for current and future asbestos claims through 2027.
Management believes that it is possible there will be additional claims filed against Duke Energy Carolinas after 2027. In light of the uncertainties inherent in a longer-term forecast, management does not believe that they can reasonably estimate
the indemnity and medical costs that might be incurred after 2027 related to such potential claims. Asbestos-related loss estimates incorporate anticipated inflation, if applicable, and are recorded on an undiscounted basis. These reserves are based
upon current estimates and are subject to greater uncertainty as the projection period lengthens. A significant upward or downward trend in the number of claims filed, the nature of the alleged injury, and the average cost of resolving each such
claim could change Duke Energy Carolinas estimated liability, as could any substantial adverse or favorable verdict at trial. A federal legislative solution, further state tort reform or structured settlement transactions could also change the
estimated liability. Given the uncertainties associated with projecting matters into the future and numerous other factors outside the control of Duke Energy Carolinas, management believes that it is possible Duke Energy Carolinas may incur asbestos
liabilities in excess of the recorded reserves.

Duke Energy Carolinas has a third-party insurance policy to cover certain
losses related to Duke Energy Carolinas asbestos-related injuries and damages above an aggregate self insured retention of $476 million. Duke Energy Carolinas cumulative payments began to exceed the self insurance retention on its
insurance policy during the second quarter of 2008. Future payments up to the policy limit will be reimbursed by Duke Energy Carolinas third-party insurance carrier. The insurance policy limit for potential future insurance recoveries for
indemnification and medical cost claim payments is $1,051 million in excess of the self insured retention. Insurance recoveries of approximately $984 million and $1,032 million related to this policy are classified in the Consolidated Balance Sheets
in Other within Investments and Other Assets and Receivables as of December 31, 2009 and December 31, 2008, respectively. Duke Energy Carolinas is not aware of any uncertainties regarding the legal sufficiency of insurance claims.
Management believes the insurance recovery asset is probable of recovery as the insurance carrier continues to have a strong financial strength rating.

Other Litigation and Legal Proceedings. Duke Energy Carolinas is involved
in other legal, tax and regulatory proceedings arising in the ordinary course of business, some of which involve substantial amounts. Duke Energy Carolinas believes that the final disposition of these proceedings will not have a material adverse
effect on its consolidated results of operations, cash flows or financial position.

Duke Energy Carolinas has exposure to
certain legal matters that are described herein. As of December 31, 2009 and December 31, 2008, Duke Energy Carolinas has recorded reserves, including reserves related to the aforementioned asbestos-related injuries and damages claims, of
approximately $1 billion and $1.1 billion, respectively, for these proceedings and exposures. These reserves represent managements best estimate of probable loss as defined in the accounting guidance for contingencies. Duke Energy Carolinas
has insurance coverage for certain of these losses incurred. As of December 31, 2009 and December 31, 2008, Duke Energy Carolinas recognized approximately $984 million and $1,032 million, respectively, of probable insurance recoveries
related to these losses.

Duke Energy Carolinas expenses legal costs related to the defense of loss contingencies as incurred.

Other Commitments and Contingencies

General. As part of its normal business, Duke Energy Carolinas enters into various fixed-price, non-cancelable commitments to purchase or sell power (tolling arrangements or power purchase
contracts) that may or may not be recognized on the Consolidated Balance Sheets. Some of these arrangements may be recognized at market value on the Consolidated Balance Sheets as derivatives or qualifying hedge positions. See Note 8 for further
discussion regarding Duke Energy Carolinas derivative activity.

Operating and Capital Lease Commitments

Duke Energy Carolinas leases assets in several areas of its operations. Consolidated rental expense for operating leases was $56 million in
2009, $85 million in 2008 and $48 million in 2007, which is included in Operation, Maintenance and Other on the Consolidated Statements of Operations. Duke Energy Carolinas has no capital leases as of December 31, 2009. The following is a
summary of future minimum lease payments under operating leases, which at inception had a noncancelable term of more than one year, as of December 31, 2009:

15. Employee Benefit Plans

Duke Energy Retirement Plans.Duke Energy Carolinas participates in Duke Energys qualified non-contributory defined benefit
retirement plans. The plans cover most U.S. employees using a cash balance formula. Under a cash balance formula, a plan participant accumulates a retirement benefit consisting of pay credits that are based upon a percentage (which may vary with age
and years of service) of current eligible earnings and current interest credits.

Duke Energys policy is to fund amounts
on an actuarial basis to provide assets sufficient to meet benefits to be paid to plan participants. In 2009, Duke Energy Carolinas made a cash contribution of approximately $158 million to Duke Energys qualified pension plan. Duke Energy
Carolinas did not make any contributions to Duke Energys defined benefit plans during the years ended December 31, 2008 or 2007.

Actuarial gains and losses are amortized over the average remaining service period of the active employees. The average remaining service period of the active employees covered by the qualified retirement
plans is 11 years. Duke Energy determines the market-related value of plan assets using a calculated value that recognizes changes in fair value of the plan assets in a particular year on a straight-line basis over the next five years.



Net periodic pension costs disclosed in the tables below for
the qualified, non-qualified and other post-retirement benefit plans represent the cost of the respective plan for the periods presented. However, portions of the net periodic pension costs (benefits) disclosed in the tables have been capitalized as
a component of property, plant and equipment. As required by applicable accounting rules, Duke Energy uses a December 31 measurement date for its plan assets.

Since Duke Energy is the sponsor of the qualified pension plans, non-qualified pension plans and other post-retirement benefit plans, Duke Energy Carolinas does not have any amounts reflected on its
Consolidated Balance Sheets related to obligations associated with such plans.

Amounts presented in the tables below
represent the amounts of pension and other post-retirement benefit cost allocated by Duke Energy for employees of Duke Energy Carolinas. Additionally, Duke Energy Carolinas is allocated its proportionate share of pension and other post-retirement
benefit cost for employees of Duke Energys shared services affiliate that provides support to Duke Energy Carolinas. These allocated amounts are included in the governance and shared services costs discussed in Note 11.

The fair value of Duke Energys plan assets (excluding plans sponsored by Cinergy Corp. (Cinergy), a
wholly-owned subsidiary of Duke Energy effective with a merger in April 2006), was approximately $2,296 million as of December 31, 2009 and approximately $1,743 million as of December 31, 2008. The projected benefit obligation of Duke
Energys plan (excluding Cinergy plans), was approximately $2,467 million as of December 31, 2009 and approximately $2,169 million as of December 31, 2008. The accumulated benefit obligation of Duke Energys plan (excluding
Cinergy plans) was approximately $2,384 million as of December 31, 2009 and approximately $2,094 million as of December 31, 2008.

Non-Qualified Pension Plans

Net periodic pension expense was approximately $2 million for each of the
years ended December 31, 2009, 2008 and 2007, respectively.

Other Post-Retirement Benefit Plans

In conjunction with Duke Energy, Duke Energy Carolinas provides some health care and life insurance benefits for retired employees on a
contributory and non-contributory basis. Employees are eligible for these benefits if they have met age and service requirements at retirement, as defined in the plans.

These benefit costs are accrued over an employees active service period to the date of full benefits eligibility. The net unrecognized transition obligation is amortized over approximately 20 years.
Actuarial gains and losses are amortized over the average remaining service period of the active employees. The average remaining service period of the active employees covered by the plan is 12 years.

17. Subsequent Events

For information on subsequent events related to regulatory matters, related parties and commitments and contingencies, see Notes 4, 11 and 14, respectively.

In January 2010, Duke Energy announced plans to offer a voluntary severance plan to approximately 8,750 eligible employees. As this is a
voluntary plan, all severance benefits offered under this plan are considered special termination benefits under GAAP. Special termination benefits are measured upon employee acceptance and recorded immediately absent a significant retention period.
If a significant retention period exists, the cost of the special termination benefits are recorded ratably over the remaining service periods of the affected employees. The window for employees to request to voluntarily end their employment under
this plan opened on February 3, 2010 and closed on February 24, 2010 for 8,400 eligible employees, which includes approximately 4,033 Duke Energy Carolinas employees. Additionally, Duke Energy Carolinas will be allocated its proportionate
share of benefit costs for employees of Duke Energys shared services affiliate that provides support to Duke Energy Carolinas. Duke Energy Carolinas currently estimates severance payments associated with this voluntary plan, including
allocated costs discussed above, of approximately $84 million. However, until management of Duke Energy approves the requests, it reserves the right to reject any request to volunteer based on business needs and/or excessive participation.

Item 9. Changes in and Disagreements with Accountants on Accounting and
Financial Disclosure.

None.

Item 9A. Controls and Procedures.

Disclosure Controls and
Procedures

Disclosure controls and procedures are controls and other procedures that are designed to ensure that
information required to be disclosed by Duke Energy Carolinas in the reports it files or submits under the Securities Exchange Act of 1934 (Exchange Act) is recorded, processed, summarized, and reported, within the time periods
specified by the Securities and Exchange Commissions (SEC) rules and forms.

Disclosure controls and procedures include,
without limitation, controls and procedures designed to provide reasonable assurance that information required to be disclosed by Duke Energy Carolinas in the reports it files or submits under the Exchange Act is accumulated and
communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of management, including the Chief Executive Officer and Chief Financial Officer, Duke Energy Carolinas has evaluated the effectiveness of its disclosure
controls and procedures (as such term is defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31, 2009, and, based upon this evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that these
controls and procedures are effective in providing reasonable assurance of compliance.

Changes in Internal Control over Financial
Reporting

Under the supervision and with the participation of management, including the Chief Executive Officer and Chief
Financial Officer, Duke Energy Carolinas has evaluated changes in internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the fiscal quarter ended
December 31, 2009 and other than the fourth quarter system change described below, have concluded that no change has materially affected, or is reasonably likely to materially affect, internal control over financial reporting.

During the fourth quarter of 2009, Duke Energy Carolinas implemented a new system for online customer billing and payment. The system change
is a result of an evaluation of the previous system and related processes to support evolving operational needs and is not the result of any identified deficiencies in the previous systems. Duke Energy Carolinas reviewed the implementation effort as
well as the impact on Duke Energy Carolinas internal control over financial reporting and where appropriate, made changes to internal controls over financial reporting to address these system changes.

Managements Annual Report On Internal Control Over Financial Reporting

Duke Energy Carolinas management is responsible for establishing and maintaining an adequate system of internal control over financial
reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Our internal control system was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements
for external purposes, in accordance with generally accepted accounting principles in the United States. Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also projections of any
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies and procedures may deteriorate.

Duke Energy Carolinas management, including our Chief Executive Officer and Chief Financial Officer, has conducted an evaluation of
the effectiveness of our internal control over financial reporting as of December 31, 2009 based on the framework in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway
Commission. Based on that evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2009.

This annual report does not include an attestation report of Deloitte & Touche LLP, Duke Energy Carolinas registered independent public accounting firm, regarding internal control over
financial reporting. Managements report was not subject to attestation by Deloitte & Touche LLP pursuant to temporary rules of the SEC that permit Duke Energy Carolinas to provide only managements report in this annual report.

To safeguard the continued
independence of the independent auditor, the Duke Energy Audit Committee adopted a policy that provides that the independent public accountants are only permitted to provide services to Duke Energy and its consolidated subsidiaries, including Duke
Energy Carolinas that have been pre-approved by the Duke Energy Audit Committee. Pursuant to the policy, detailed audit services, audit-related services, tax services and certain other services have been specifically pre-approved up to certain fee
limits. In the event that the cost of any of these services may exceed the pre-approved limits, the Duke Energy Audit Committee must pre-approve the service. All other services that are not prohibited pursuant to the Securities and Exchange
Commissions or other applicable regulatory bodies rules of regulations must be specifically pre-approved by the Duke Energy Audit Committee. All services performed in 2009 and 2008 by the independent public accountant were approved by
the Duke Energy Audit Committee pursuant to its pre-approval policy.
