DUKE ENERGY CAROLINAS, LLC

Notes To Unaudited Consolidated Financial Statements



1. Basis of Presentation

Nature of Operations and Basis of Consolidation. Duke Energy Carolinas, LLC (Duke Energy Carolinas), a wholly owned subsidiary of Duke Energy Corp. (Duke
Energy), generates, transmits, distributes and sells electricity in North Carolina and South Carolina. These Unaudited Consolidated Financial Statements include, after eliminating intercompany transactions and balances, the accounts of Duke Energy
Carolinas, as well as Duke Energy Carolinas approximate 19% undivided interest in the Catawba Nuclear Station (see Note 3 for discussion of Duke Energy Carolinas acquisition of additional ownership interest in the Catawba Nuclear Station
in September 2008).

These Unaudited Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles
(GAAP) in the United States of America (U.S.) for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, these Unaudited Consolidated Financial Statements and Notes do not include all of the information
and notes required by GAAP in the U.S. for annual financial statements. Because the interim Unaudited Consolidated Financial Statements and Notes do not include all of the information and notes required by GAAP in the U.S. for annual financial
statements, the Unaudited Consolidated Financial Statements and other information included in this quarterly report should be read in conjunction with the Consolidated Financial Statements and Notes in Duke Energy Carolinas Form 10-K for the
year ended December 31, 2008.

These Unaudited Consolidated Financial Statements reflect all normal recurring adjustments that are, in the
opinion of management, necessary to fairly present Duke Energy Carolinas financial position and results of operations. Amounts reported in the interim Unaudited Consolidated Statements of Operations are not necessarily indicative of amounts
expected for the respective annual periods due to the effects of seasonal temperature variations on energy consumption, regulatory rulings, the timing of maintenance on electric generating units, changing commodity prices and other factors.

Use of Estimates. To conform to GAAP in the U.S., management makes estimates and assumptions that affect the amounts reported in the Unaudited
Consolidated Financial Statements and Notes. Although these estimates are based on managements best available information at the time, actual results could differ.

Unbilled Revenue. Revenues on sales of electricity are recognized when the service is provided. Unbilled retail revenues are estimated by applying an average revenue per kilowatt-hour for all customer classes to the
number of estimated kilowatt-hours 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 not yet billed. The amount of unbilled revenues can vary significantly from period to period as a result of factors, including seasonality,
weather, customer usage patterns and customer mix. Unbilled revenues, which are primarily recorded as Receivables in Duke Energy Carolinas Consolidated Balance Sheets at March 31, 2009 and December 31, 2008, were approximately $204
million and $268 million, respectively.

Other Current and Non-Current Liabilities.At both March 31, 2009 and December 31, 2008,
approximately $89 million of liabilities associated with vacation accrued were included in Other Current Liabilities in the Consolidated Balance Sheets. At March 31, 2009, this balance exceeded 5% of total current liabilities. Additionally, at
March 31, 2009 and December 31, 2008, approximately $1,444 million and $1,481 million, respectively, of regulatory liabilities associated with asset removal costs are included in Other within Deferred Credits and Other Liabilities in the
Consolidated Balance Sheets. At March 31, 2009, this balance exceeded 5% of total liabilities. Also see Asbestos-related Injuries and Damages Claims in Note 10 for additional amounts that exceeded 5% of total liabilities.

2. Business Segments

Duke Energy Carolinas operates one
business segment, Franchised Electric, which is considered a reportable business segment under Financial Accounting Standards Board (FASB) Statement of Financial Accounting Standards (SFAS) No. 131, Disclosures about Segments of
an Enterprise and Related Information. Franchised Electric generates, transmits, distributes and sells electricity and conducts operations through Duke Energy Carolinas, which consists of the regulated electric utility business in North
Carolina and South Carolina. Duke Energy Carolinas chief operating decision maker regularly reviews financial information about the business segment in deciding how to allocate resources and evaluate performance. There is no aggregation within
the Franchised Electric reportable 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 unallocated corporate governance costs. Prior to July 1, 2008, Other also included a management fee charged by an unconsolidated affiliate (see Note 11). Effective July 1,
2008, the management fee was no longer charged to Duke Energy Carolinas.

DUKE ENERGY CAROLINAS,
LLC

Notes To Unaudited Consolidated Financial Statements(Continued)



Accounting policies for Duke Energy Carolinas segment are the same as those described in the Notes to the Consolidated Financial
Statements in Duke Energy Carolinas Annual Report on Form 10-K for the year ended December 31, 2008. Management evaluates segment performance based on earnings before interest and taxes from continuing operations.

On a segment basis, EBIT excludes discontinued operations, 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 cash, cash equivalent and short-term investment balances are excluded from segment EBIT.

Segment Assets

At March 31, 2009 and December 31, 2008, substantially all of Duke Energy Carolinas segment assets are
owned by its only reportable business segment, Franchised Electric.

3. Acquisitions of Businesses

Acquisitions. Duke Energy Carolinas consolidates assets and liabilities from acquisitions as of the purchase date, and includes results of operations from
acquisitions in consolidated earnings after the purchase date. Assets acquired and liabilities assumed are recorded at estimated fair values on the purchase date. The purchase price minus the estimated fair value of the acquired assets and
liabilities meeting the definition of a business as defined in SFAS No. 141 (revised 2007), Business Combinations, (SFAS No. 141R) is recorded as goodwill. The allocation of the fair value of all consideration
transferred may be adjusted when additional, requested information is received during the allocation period, which generally does not exceed one year from the consummation date. Effective January 1, 2009, Duke Energy Carolinas adopted SFAS
No. 141R, which applies to all acquisitions after December 31, 2008.

On September 30, 2008, Duke Energy Carolinas completed the
purchase of a portion of Saluda River Electric Cooperative, Inc.s (Saluda) ownership interest in the Catawba Nuclear Station. Under the terms of the agreement, Duke Energy Carolinas paid approximately $150 million for the additional ownership
interest in the Catawba Nuclear Station. Following the closing of the transaction, Duke Energy Carolinas owns approximately 19% of the Catawba Nuclear Station. No goodwill was recorded as a result of this transaction. See Note 9 for discussion of
the North Carolina Utilities Commission (NCUC) and Public Service Commission of South Carolina (PSCSC) approval of Duke Energy Carolinas petition requesting an accounting order to defer incremental costs incurred from the purchase of this
additional ownership interest.

4. Stock-Based Compensation

Duke Energy
Carolinas is allocated stock-based compensation expense from Duke Energy as certain of its employees participate in Duke Energys stock-based compensation program. Duke Energy Carolinas accounts for stock-based compensation using the provisions
of SFAS No. 123(R), Share-Based Payment (SFAS No. 123(R)). SFAS No. 123(R) established accounting for stock-based awards exchanged for employee and certain nonemployee services. Accordingly, for employee awards,
equity classified stock-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as expense over the requisite service period.

Duke Energy Carolinas recorded pre-tax stock-based compensation expense for each of the three months ended March 31, 2009 and 2008 as follows:



|                   |  |                            |   |      |   |

6. Debt and Credit Facilities

First and Refunding Mortgage Bonds. In January 2008, Duke Energy Carolinas issued $900 million principal amount of mortgage refunding 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, which 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.

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 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 replaces 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 March 31, 2009 and December 31, 2008, Duke Energy Carolinas had net
short-term money pool receivables of approximately $292 million and $338 million, respectively, which are classified within Receivables in the accompanying Consolidated Balance Sheets. At both March 31, 2009 and December 31, 2008, $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. The $46 million decrease in the money pool receivable for the three months
ended March 31, 2009 is reflected as a cash inflow in Notes due from affiliate, net within Net cash used in investing activities on the Consolidated Statements of Cash Flows.

Available Credit Facilities.The total credit facility capacity under Duke Energys master credit facility is approximately $3.14 billion. Duke Energy
has the unilateral ability under the master credit facility to increase or decrease the borrowing sub limits of each borrower, subject to maximum cap limitation, at any time. At March 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 issuances of letters of credit and pollution control bonds, as discussed below.

At both March 31, 2009 and
December 31, 2008, approximately $422 million of certain pollution control bonds and approximately $300 million of money pool borrowings, 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. Of the $422 million of pollution control bonds outstanding at March 31, 2009, approximately $195 million were backstopped by Duke
Energys master credit facility (of which approximately $100 million is in the form of letters of credit), with the remaining balance backstopped by other specific credit facilities

separate from the master credit facility. Additionally, at March 31, 2009, Duke Energy Carolinas had approximately $7 million of letters of credit outstanding
that were backstopped by this facility.

Restrictive Debt Covenants. Duke Energys 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 March 31, 2009, Duke Energy and Duke Energy Carolinas were in compliance with all
covenants. 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.

7. Employee Benefit Obligations

Duke Energy Carolinas participates in Duke Energys qualified pension plans, non-qualified pension plans and other post-retirement benefit plans. Duke
Energys policy is to fund amounts for its U.S. qualified pension plans on an actuarial basis to provide assets sufficient to meet benefit payments to be paid to plan participants. In February 2009, Duke Energy Carolinas made a cash
contribution of approximately $74 million, which represented its proportionate share of an approximate $107 million contribution (excluding Cinergy plans) to Duke Energys qualified pension plan. Duke Energy Carolinas did not make contributions
to Duke Energys U.S. qualified or non-qualified pension plans during the three months ended March 31, 2008. Duke Energy Carolinas does not anticipate making additional contributions to its qualified or non-qualified pension plans during
the remainder of 2009. Additionally, Duke Energy Carolinas participates in Duke Energy sponsored employee savings plans that cover substantially all U.S. employees. Duke Energy Carolinas expensed its proportionate share of pre-tax employer matching
contributions of approximately $11 million and $12 million in the three months ended March 31, 2009 and 2008, respectively.

Net periodic pension
cost (benefit) discussed below for the qualified, non-qualified and other post-retirement benefit plans represent the allocated cost of the respective pension plan for the periods presented. However, portions of the net periodic pension cost
(benefit) discussed below have been capitalized as a component of property, plant and equipment.

Qualified Pension Plans

Net periodic pension (benefit) costs for qualified pension plans for Duke Energy Carolinas, as allocated by Duke Energy, was approximately $(2) million and $2
million for the three months ended March 31, 2009 and 2008, respectively.

Non-Qualified Pension Plans

Net periodic pension costs for non-qualified pension plans for Duke Energy Carolinas, as allocated by Duke Energy, was approximately $1 million for each of the
three months ended March 31, 2009 and 2008.

Other Post-Retirement Benefit Plans

Net periodic costs for other post-retirement benefit plans for Duke Energy Carolinas, as allocated by Duke Energy, was approximately $4 million and $5 million for
the three months ended March 31, 2009 and 2008, respectively.

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
are designated as hedging instruments under SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities (SFAS No. 133, 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 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.

SFAS No. 133
requires the recognition of all derivative instruments as either assets or liabilities at fair value in the Consolidated Balance Sheets. In accordance with SFAS No. 133, Duke Energy Carolinas may elect to designate qualifying commodity and
interest rate derivatives as either cash flow hedges or fair value hedges. Additionally, Duke Energy Carolinas enters into derivative agreements that are



13

PART I

DUKE ENERGY CAROLINAS,

Notes To Unaudited Consolidated Financial Statements(Continued)



economic hedges that either do not qualify for hedge accounting or have not been designated as a hedge. As substantially all of Duke Energy Carolinas operations apply
the provisions of SFAS No. 71, gains and losses associated with undesignated contracts, are deferred as regulatory liabilities and assets, respectively, thus there is no immediate earnings impact associated with the change in fair values
associated with these 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 (sulfur dioxide (SO2), seasonal nitrogen oxide (NOX) and annual NOX) as a result of its energy operations in 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 NOX and 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 assets or liabilities under SFAS No. 71. Additionally, Duke Energy Carolinas enters into various contracts
that qualify for the normal purchase and normal sales (NPNS) exception described in paragraph 10 of SFAS No. 133, as amended. Duke Energy Carolinas primarily applies the NPNS exception to contracts within the U.S. Franchised Electric and Gas
business segments that relate to the physical delivery of electricity over the current year.

Commodity Fair Value Hedges.At March 31,
2009, Duke Energy Carolinas did not have any open commodity derivative instruments that were designated as fair value hedges under SFAS No. 133.

Commodity Cash Flow Hedges. At March 31, 2009, Duke Energy Carolinas did not have any open commodity derivative instruments that were designated as cash flow hedges under SFAS No. 133.

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. The contracts in this category as of March 31, 2009 are associated with forward power sales.

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 and commercial paper. 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 March 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 Income (AOCI) and is being amortized as a component of interest expense over the life of the debt.

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

During the three months ended March 31, 2009, approximately $1 million of pre-tax losses on interest rate hedges was reclassified from AOCI
and recorded in the Consolidated Statements of Operations. As of March 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 AOCI are expected to be recognized in earnings during the next twelve months as the hedged transactions occur.

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

During the three months ended
March 31, 2009, an insignificant amount of net mark-to-market losses were recorded in the Consolidated Balance Sheets as a reduction to Regulatory Liabilities.

See Note 12 for additional information on fair value disclosures related to derivatives required by SFAS No. 157, Fair Value Measurements (SFAS No. 157).

9. Regulatory Matters

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 rates.

Duke Energy Carolinas 2007 Rate Case. The NCUC issued its Order Approving Stipulation and Deciding Non-Settled Issues (Order) on December 20,
2007. The Order 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 in keeping with traditional principles of rate making. The NCUC
explained that because rates should be designed to recover a reasonable and prudent level of ongoing expenses, Duke Energy Carolinas annual cost of service and revenue requirement should reflect, as closely as possible, Duke Energy
Carolinas actual costs. However, the NCUC recognized that its treatment of merger savings would not produce a fair result. Therefore, the NCUC preliminarily concluded that it would reconsider certain language in its 2006 merger order in order
to allow it to authorize 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. 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. On February 18, 2008, the NCUC issued an order confirming their preliminary conclusion regarding the merger savings rider and the $80
million increment rider. Duke Energy Carolinas implemented the rate rider effective January 1, 2008 and terminated the rider effective January 1, 2009.

Energy Efficiency. On May 7, 2007, Duke Energy Carolinas filed its save-a-watt application with the NCUC. 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. Intervenor comments on this filing are due May 22, 2009. Duke Energy Carolinas reply
comments are due June 12, 2009. Duke Energy Carolinas will begin offering conservation programs to North Carolina retail customers on June 1, 2009.

On February 25, 2009, the PSCSC denied Duke Energy Carolinas save-a-watt application in Docket 2007-358-E. On April 15, 2009, Duke Energy Carolinas filed a Petition for Approval of Energy Efficiency Programs and An
Accounting Order to Defer Costs Incurred in Connection with Development and Implementation of Energy Efficiency Programs with the PSCSC. Duke Energy Carolinas South Carolina petition requests (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. On May 6, 2009, the PSCSC approved the petition as requested. Duke Energy Carolinas will begin offering demand response and conservation programs effective June 1, 2009.

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 electricity generating solar panels at up to 850 North Carolina sites including homes, schools, stores and factories under the
Program. The Program will help Duke Energy Carolinas meet the requirement of North Carolinas Renewable 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 electrical generating facilities, the NCUC must issue Duke Energy Carolinas a
Certificate of Public Convenience and Necessity before it may proceed. The REPS statute provides for the recovery of costs Duke Energy Carolinas incurs to comply with its requirements, principally through an annual rate rider.

Prior to the evidentiary hearing on October 23, 2008, and 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 MWs of solar photovoltaic capacity. Based upon the revised size and availability of state and federal tax credits, Duke Energy Carolinas estimates that the
Program would result in a monthly charge of approximately $0.08 for residential customers. On December 31, 2008, the NCUC issued its Order Granting a Certificate of Public Convenience and Necessity (CPCN) Subject to Conditions. The conditions
are (i) reduction of the program size from 20 MWs to 10 MWs (as previously agreed upon by Duke Energy Carolinas); and (ii) limiting 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 leaves open the opportunity to recover the excess costs through other recovery mechanisms.

Notes To Unaudited Consolidated Financial Statements(Continued)



Because the Order creates a risk that Duke Energy Carolinas would violate tax normalization rules associated with renewable tax
credits, Duke Energy Carolinas filed a motion for reconsideration on January 29, 2009. The NCUC set a briefing schedule and scheduled oral argument on the motion for reconsideration on March 23, 2009. Prior to the oral argument, Duke
Energy Carolinas filed both initial and rebuttal briefs in support of its motion for reconsideration. In its briefs, Duke Energy Carolinas requested that the NCUC withdraw the Order in its entirety and issue a new order consistent with one of the
three alternatives forms of relief designed to permit all Program costs to be recovered through the REPS rider or to clarify the Order and provide adequate assurance of recovery so as to avoid a normalization violation and correct the Orders
unintended implication that compliance with the tax law might not be reasonable and prudent.

On May 6, 2009, 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
certain environmental compliance costs and the incremental costs incurred from the purchase of a portion of Saluda Rivers 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 is seeking 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 on-going basis. On
February 25, 2009, the PSCSC approved the deferral of these costs. The NCUC granted Duke Energy Carolinas request to defer costs for both Allen Steam Station and the Catawba Nuclear Station on March 31, 2009 and Duke Energy Carolinas
began deferring the costs in the first quarter of 2009.

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 (NERC) Reliability Standards. This investigation was coordinated with on an ongoing Compliance Violation Investigation (CVI) conducted by SERC
Reliability Corporation (SERC). 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) 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 February 25, 2008, Duke Energy Carolinas received confirmation from the NRC that its COL
application has been accepted and docketed for the next stage of review. On June 27, 2008, the Blue Ridge Environmental Defense League (BREDL) filed a petition to intervene in the COL proceeding before the NRC. On September 22, 2008, the
Atomic Safety and Licensing Board issued a decision denying BREDLs Petition to Intervene and Request for Hearing. BREDL did not appeal the decision. 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 Carolinas 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 Lee 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 denied the environmental intervenor motions. The NRC review of the COL application is ongoing and the current schedule concludes the COL may be granted in early 2012. Duke
Energy Carolinas filed with the DOE for a federal loan guarantee. Duke Energy Carolinas filed Part 1 applications in September 2008 and a Part II application in December 2008. If obtained, a federal loan guarantee has the potential to significantly
lower financing costs associated with the proposed William States Lee III Nuclear Station.

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. The NCUCs Order explained the basis for its decision to approve construction of one unit, with an approved cost estimate of $1.93 billion (including allowance for funds used during construction (AFUDC)), and
included certain conditions including providing for updates on construction cost estimates. A group of environmental intervenors filed a motion and supplemental motion for reconsideration in April 2007 and May 2007, respectively. On May 6, 2009,
North Carolina Waste Awareness Reduction Network filed a motion to revoke the CPCN. The NCUC denied the motions for reconsideration in June 2007. 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 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 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 were filed appealing the final air permit. Duke Energy intervened in all four cases which have been consolidated. A hearing is not expected before the end of 2009. See Note
10 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 because Cliffside Unit 6 has
been demonstrated to be a minor source of HAPs. On October 24, 2008, Duke Energy Carolinas filed to amend its air permit to include emission limits to assure the public of the minor source status of Cliffside Unit 6. The DAQ held public
hearings on January 15, 2009, in Forest City, North Carolina and January 22, 2009, in Statesville, North Carolina to allow public comment on the DAQs proposal to find Cliffside Unit 6 as a minor source of hazardous air pollutants.
The meeting notices were accompanied with a draft permit that includes the minor source limits and monitoring requirements that make the limits enforceable. The DAQ issued the revised permit on March 13, 2009, finding that Cliffside Unit 6 is a
minor source of HAPs and imposing additional conditions to assure that emissions stay below the major source threshold.

Dan River Steam Station
and Buck Steam Station. 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. 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, which has resulted in a modification of the construction schedule. Under the revised schedule, the Buck Project is expected to be delayed for a period of up to one year and is currently anticipated to begin operation in simple cycle
mode in summer 2011 and is expected to convert to combined cycle mode in summer 2012. The Dan River Project is expected to begin operation in combined cycle mode in 2012 as originally planned, but without a phased-in simple cycle commercial
operation.

On October 15, 2008 DAQ issued a final construction permit authorizing construction of the Buck combined cycle natural gas-fired
generating 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 U.S. Department of Energy and the
U.S. Department of the Treasury. On November 10, 2008, the District Court dismissed the case, finding that plaintiffs lacked standing to pursue their claims. The plaintiffs motion for reconsideration of the ruling remains pending.

Other Matters

City of Orangeburg, South Carolina
Wholesale Sales.On June 28, 2008, Duke Energy Carolinas filed notice with the NCUC, that it intends 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 at system average costs). The Public
Staff, the Attorney Generals Office, Progress Energy Carolinas and other large customer and environmental groups have opposed Duke Energy Carolinas notice and declaratory judgment petition. The City of Fayetteville, North Carolina and
the City of Greenwood, South Carolina are supporting Duke Energy Carolinas petition. The NCUC held an oral argument and evidentiary hearing November 5-6, 2008. Briefs and proposed orders were filed on December 30, 2008. 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. 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. A concurrence and dissent was issued by the NCUC Chairman, in
which he identified possible preemption and other constitutional arguments against the majoritys decision. The City of Orangeburg has terminated its contract with Duke Energy Carolinas and informed Duke Energy Carolinas that it will continue
to take service from South Carolina Electric & Gas Company through the end of 2010. Duke Energy Carolinas and the City of Orangeburg filed a joint Notice of Appeal to the North Carolina Court of Appeals.

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 their load, Duke Energy Carolinas will seek to distinguish these contracts from the
Orangeburg decision.

10. Commitments and Contingencies

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 affiliate operations.
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.

Clean Water Act 316(b). The Environmental Protection Agency (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
plaintiff 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 8 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 NOx emissions and annual SO2 emissions from electric generating facilities across the Eastern U.S. through a two-phased cap-and-trade program. Phase 1 begins in 2009 for NOx and in 2010 for
SO2. Phase 2 begins in 2015 for both NOx and SO2. On March 25, 2008, the U.S. Court of Appeals for the District of Columbia (D.C. Circuit) heard oral arguments 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 court did not impose a deadline or schedule on the EPA. 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 clean air legislation will contribute significantly to achieving compliance with CAIR requirements. Duke Energy Carolinas is currently unable to estimate the costs to comply with any new rule 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 $140 million over the period 2009-2013 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.

Extended Environmental Activities and Accruals. Included in Other within Deferred Credits on the Consolidated Balance Sheets were total
accruals related to extended environmental-related activities of approximately $15 million as of both March 31, 2009 and December 31, 2008. 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.

Litigation

New Source Review (NSR). In 1999-2000, the U.S. Department of Justice, 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, NOx and particulate matter. The complaints seek injunctive relief to require installation of pollution control technology on various allegedly violating generating units, 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 maximum achievable control technology (MACT) emission limits will be met
for all prospective 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 June
2008, Duke Energy Carolinas announced that it would voluntarily perform a MACT assessment of air emission controls planned for Cliffside Unit 6. In July 2008, Duke Energy Carolinas submitted the results of the assessment to the North Carolina
Department of Environment and Natural Resources. On August 8, 2008 the plaintiffs filed a motion for summary judgment and on August 11, 2008 Duke Energy Carolinas filed a motion to dismiss. Both motions were argued on October 16,
2008. 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 the DAQs concurrence as a threshold
matter that construction of Cliffside Unit 6 is not a major source subject to section 112 of the Clean Air Act and submitting a MACT determination application. The DAQ held public hearings on January 15, 2009 in Forest City, North Carolina and
January 22, 2009 in Statesville, North Carolina to allow public comment on the DAQs proposal to find Cliffside Unit 6 a minor source of HAPs. The meeting notices were accompanied with a draft permit that includes the minor source limits
and monitoring requirements that make the limits enforceable. The DAQ issued the revised permit on March 13, 2009, finding that Cliffside Unit 6 is a minor source of HAPs and imposing additional conditions to assure that emissions stay below
the major source threshold. A trial on any residual issues is scheduled for August 2009. 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 trial court has set a trial commencing in June 2009 to hear outstanding remedy issues.

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 need 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. The 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. No trial date has been set. At mediation, 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 or Duke Energy Carolinas 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 $1,019 million and $1,031 million as of March 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 our control, 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
$1,074 million in excess of the self insured retention. Insurance recoveries of approximately $1,007 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 March 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 March 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. Duke Energy Carolinas has insurance coverage for certain of these losses incurred. The reserves represent managements best estimate of probable loss
as defined by SFAS No. 5, Accounting for Contingencies. As of March 31, 2009 and December 31, 2008, Duke Energy Carolinas recognized approximately $1,007 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.

Duke Energy Carolinas is charged its proportionate share of corporate governance and other costs by
an unconsolidated affiliate that is a consolidated affiliate of Duke Energy. Corporate governance and other shared services costs are primarily related to human resources, employee benefits, legal and accounting fees, as well as other third party
costs. During the three months ended March 31, 2009 and 2008, Duke Energy Carolinas recorded governance and shared services expenses of approximately $191 million and $187 million, respectively. Additionally, as discussed in Note 2, up through
June 30, 2008, Duke Energy Carolinas was charged a management fee by the same unconsolidated affiliate. This management fee amounted to approximately $18 million for the three months ended March 31, 2008. These amounts are recorded in
Operation, Maintenance and Other within Operating Expenses on the Consolidated Statements of Operations.

Duke Energy Carolinas incurs expenses
related to its insurance coverage through Bison Insurance Company Limited, Duke Energys wholly-owned captive insurance subsidiary. These amounts were approximately $7 million for each of the three months ended March 31, 2009 and 2008.
These expenses are recorded in Operation, Maintenance and Other within Operating Expenses on the Consolidated Statements of Operations. Additionally, Duke Energy Carolinas records income associated with the rental of office space to a consolidated
affiliate of Duke Energy. This rental income was approximately $4 million and $3 million for the three months ended March 31, 2009 and 2008, respectively.

As discussed further in Note 6, Duke Energy Carolinas participates in a money pool arrangement with Duke Energy and other Duke Energy subsidiaries. As of March 31, 2009, Duke Energy Carolinas had net receivables of
approximately $292 million, which are classified within Receivables in the accompanying Consolidated Balance Sheets, and approximately $300 million of outstanding money pool borrowings which are classified as long-term borrowings within Long-Term
Debt in the accompanying Consolidated Balance Sheets.

12. Fair Value of Financial Assets and Liabilities

On January 1, 2008, Duke Energy Carolinas adopted SFAS No. 157. Through December 31, 2008, Duke Energy Carolinas adoption of SFAS No. 157
was limited to financial instruments and to non-financial derivatives as, in February 2008, the Financial Accounting Standards Board (FASB) issued FASB Staff Position (FSP) No. FAS 157-2, Effective Date of FASB Statement
No. 157, which delayed the effective date of SFAS No. 157 until January 1, 2009 for non-financial assets and liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a
recurring basis. There was no cumulative effect adjustment to retained earnings for Duke Energy Carolinas as a result of the adoption of SFAS No. 157.

SFAS No. 157 defines fair value, establishes a framework for measuring fair value in GAAP and expands disclosure requirements about fair value measurements. Under SFAS No. 157, 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 under SFAS No. 157 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 SFAS No. 157 does not require additional fair value measurements,
it applies to other accounting pronouncements that require or permit fair value measurements.

Notes To Unaudited Consolidated Financial Statements(Continued)



Duke Energy Carolinas determines fair value of financial assets and liabilities based on the following fair value hierarchy, as
prescribed by SFAS No. 157, which prioritizes the inputs to valuation techniques used to measure fair value into three levels:

Level 1
inputs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
occur with sufficient frequency and volume to provide ongoing pricing information. Duke Energy Carolinas does not adjust quoted market prices on Level 1 inputs for any blockage factor.

Level 2 inputsinputs other than quoted market prices included in Level 1 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.

Level 3 inputsunobservable inputs for the asset or liability.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities-including an amendment of FASB Statement No. 115 (SFAS No. 159), which
permits entities to elect to measure many financial instruments and certain other items at fair value. For Duke Energy Carolinas, SFAS No. 159 was effective as of January 1, 2008 and had no impact on amounts presented for periods prior to
the effective date. Duke Energy Carolinas does not currently have any financial assets or financial liabilities for which the provisions of SFAS No. 159 have been elected. However, in the future, Duke Energy Carolinas may elect to measure
certain financial instruments at fair value in accordance with this standard.

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 March 31, 2009 and December 31, 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 nuclear decommissioning trust fund (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, NYSE, NYMEX and Chicago Board of Trade, as well as pink sheets, which is an
electronic quotation system that displays quotes for broker-dealers for many over-the-counter securities. 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 does not adjust 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: As of March 31, 2009, Duke Energy Carolinas has approximately $82 million par value
(approximately $70 million fair value) of auction rate securities for which an active market does not currently exist. The vast 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 March 31, 2009 using Level 3 measurements. 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.

During the first quarter of 2009, Duke Energy Carolinas adopted the provisions of FSP No. FAS 157-4, Determining Fair Value When the Volume and Level of
Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly, and FSP No. FAS 115-2 and FAS 124-2, Recognition and Presentation of Other-Than-Temporary Impairment,
and applied the principles of these FSPs to the valuation of and accounting for its investments in auction rate debt securities. Since 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 its cost basis, management concluded that there were no other-than-temporary impairments necessary as of March 31, 2009.
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 recorded.

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.

Fair Value Disclosures Required Under FSP No. FAS 107-1 and APB 28-1,Interim Disclosures About Fair Value of Financial
Instruments. The fair value of financial instruments, excluding financial assets included in the scope of SFAS No. 157 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. Accordingly, the estimates determined as of March 31, 2009 and December 31, 2008 are not necessarily indicative of the amounts Duke Energy Carolinas could have realized in current
markets.

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.

13. Investments in Debt and Equity Securities

Duke Energy Carolinas applies SFAS No. 115, Accounting For Certain
Investments in Debt and Equity Securities, (SFAS No. 115) to its investments in debt and equity securities and classifies its investments as available-for-sale, which are reported at fair value on the Consolidated Balance Sheets.
Except for certain investments in debt and equity securities held in the NDTF, which are discussed separately below, unrealized gains and losses on investments classified as available-for-sale are included in AOCI, 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 is included in earnings. 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.

Other-than-temporary impairment analysis for debt securities is based on the
provisions of FSP No. FAS 115-2 and FAS 124-2, which is discussed further in Note 12. There were no other-than-temporary impairment charges associated with investments in debt securities during the three months ended March 31, 2009 and 2008.

Short-term investments. At both March 31, 2009 and December 31, 2008, Duke Energy Carolinas had approximately $46 million carrying
value (approximately $50 million par value) of short-term investments, which consisted of investments in auction rate debt securities that are considered available-for-sale securities under SFAS No. 115. These investments in auction rate debt
securities are classified as short-term investments as these investments either have a stated maturity within the next 12 months or Duke Energy Carolinas believes the investments are reasonably expected to be refunded within the next 12 months based
on notification of a refunding plan by the issuer. The remaining balance of investments in auction rate debt securities are included in long-term investments and are discussed further below.

Other Long-term investments. Duke Energy Carolinas invests in debt and equity securities that are held in the NDTF. Additionally, approximately $32 million
carrying value (approximately $24 million par value) of investments in auction rate debt securities have been classified as long-term at March 31, 2009 due to market illiquidity factors as a result of continued failed auctions. All of these
investments are classified as available-for-sale under SFAS No. 115 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.

As of March 31, 2009 and December 31, 2008, Duke Energy Carolinas NDTF held investments with a fair market value of approximately $1,346 million and
$1,436 million, respectively. The NDTF is managed by independent investment managers with discretion to

buy, sell and invest pursuant to the objectives set forth by the trust agreement. Therefore, Duke Energy Carolinas has limited oversight of the day-to-day management
of the NDTF investments. Since day-to-day investment decisions are not made by management of Duke Energy Carolinas, the ability to hold investments in unrealized loss positions is outside the control of Duke Energy Carolinas since buy and sell
decisions are made by the investment manager of the NDTF. Accordingly, other-than-temporary impairment losses are recorded immediately when the fair value of individual investments held in the NDTF is less than the cost basis of the investment.
However, pursuant to an order from the NCUC, all losses associated with investments in the NDTF are deferred as a regulatory asset, thus there is no impact on the earnings of Duke Energy Carolinas as a result of these other-than-temporary impairment
write-downs.

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

|(a) | Losses of approximately $166 million and $190 million as of March 31, 2009 and December 31, 2008, respectively, associated with investments held in the NDTF have been excluded from
the table since, as discussed above, day-to-day investment decisions are not made by management of Duke Energy, thus the ability to hold investments in unrealized loss positions is outside the control of Duke Energy since buy and sell decisions are
made by the investment manager of the NDTF. Accordingly, other-than-temporary impairment losses are recorded immediately when the fair value of individual investments held in the NDTF is less than the cost basis of the investment.

Debt securities held, which includes auction rate securities based on the stated maturity date, at March 31, 2009 mature as
follows: $8 million in less than one year, $78 million in one to five years, $124 million in six to ten years and $328 million thereafter.

The fair

14. New Accounting Standards

The following
new accounting standards were adopted by Duke Energy Carolinas subsequent to March 31, 2008 and the impact of such adoption, if applicable, has been presented in the accompanying Consolidated Financial Statements.

SFAS No. 141 (revised 2007), Business Combinations (SFAS No. 141R). In December 2007, the FASB issued SFAS No. 141R, which
replaces SFAS No. 141, Business Combinations. SFAS No. 141R retains the fundamental requirements in SFAS No. 141 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 establishes 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, SFAS No. 141R must be applied prospectively to business combinations
for which the acquisition date occurs on or after January 1, 2009. The impact to Duke Energy Carolinas of applying SFAS No. 141R for periods subsequent to implementation will be dependent upon the nature of any transactions within the
scope of SFAS No. 141R.

SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activitiesan amendment to FASB
Statement No. 133 (SFAS No. 161).In March 2008, the FASB issued SFAS No. 161, which amends and expands the disclosure requirements for derivative instruments and hedging activities prescribed by SFAS No. 133,Accounting for Derivative Instruments and Hedging Activities.SFAS No. 161 requires qualitative disclosures about objectives and strategies for using derivatives, 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 Carolinas adopted SFAS No. 161 as of January 1, 2009. The adoption of SFAS No. 161 did not have
any impact on Duke Energy Carolinas consolidated results of operations, cash flows or financial position. See Note 8 for disclosures required under SFAS No. 161.

FSP No. APB 14-1, Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement) (FSP
APB 14-1).In May 2008, the FASB issued FSP APB 14-1, which addressed the accounting for convertible debt securities that, upon conversion, may be settled by the issuer fully or partially in cash. FSP APB 14-1 does not change the accounting for
more traditional types of convertible debt securities that do not have a cash settlement feature and FSP APB 14-1 does not apply if, under existing GAAP for derivatives, the embedded conversion feature must be accounted for separately from the rest
of the instrument. For Duke Energy Carolinas, FSP APB 14-1 was applicable as of January 1, 2009 and must be applied retrospectively to all prior periods presented, even if the instrument has matured, has been converted, or has otherwise been
extinguished as of the effective date of FSP APB 14-1. Since FSP APB 14-1 did not change the accounting for Duke Energy Carolinas 2003 issuance of $770 million of convertible debt that was fully converted to common stock during the years ended
December 31, 2005, 2006 and 2007, the adoption of FSP APB 14-1 did not have any impact on Duke Energy Carolinas historical financial statements. Future impacts of FSP APB 14-1 will be determined by whether Duke Energy Carolinas issues
convertible debt with cash settlement options.

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

FSP No. FAS 132(R)-1, Employers Disclosure about Postretirement Benefit Plan Assets (FSP
FAS 132(R)-1).In December 2008, the FASB issued FSP FAS 132(R)-1, which amends SFAS No. 132(R) to require more detailed disclosures about employers plan assets, concentrations of risk within plan assets, and valuation techniques used
to measure the fair value of plan assets. Additionally, companies will be required to disclose their pension assets in a fashion consistent with SFAS No. 157 (i.e., Level 1, 2, and 3 of the fair value hierarchy) along with a roll-forward of the
Level 3 values each year. For Duke Energy, FSP FAS 132(R)-1 is effective for Duke Energys Form 10-K for the year ended December 31, 2009. The adoption of FSP FAS 132(R)-1 will not have any impact on Duke Energys results of
operations, cash flows or financial position.

15. Income Taxes and Other 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.

At both March 31, 2009 and December 31, 2008, 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 $32 million reduction in unrecognized tax benefits within the next twelve months due to expected settlements.

Duke Energy Carolinas has the following tax years open:

|State        |  | Majority closed through 2001 except for certain refund claims for tax years 1978-2001 and any adjustments related to open federal years

At March 31, 2009 and December 31, 2008, approximately $242 million and $202 million, respectively,
of federal income taxes receivable are included in Other within Current Assets in the Consolidated Balance Sheets. At March 31, 2009, this balance exceeded 5% of total current assets.

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 $33 million
and $32 million for the three months ended March 31, 2009 and 2008, respectively.

The effective tax rate for the three months ended
March 31, 2009 was approximately 34.3% as compared to the effective tax rate of 33.7% for the same period in 2008.

The $6 million decrease in Duke Energy Carolinas net income was primarily due to the following
factors:

Operating Revenues.The decrease was primarily due to:



| |  |  | An approximate $18 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,
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An approximate $17 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 driven by declining natural gas prices, partially offset by increased sales volumes to customer served under long-term contracts, and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An approximate $10 million decrease in weather adjusted sales volumes to retail customers reflecting both the overall declining economic conditions, which are primarily
impacting the industrial sector, and the general decline in the textile industry in the Carolinas. Industrial sales decreased by approximately 19% compared to the same period in 2008.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Partially offsetting these decreases was:



| |  |  | An approximate $12 million increase in gigawatt-hour (GWh) sales to retail customers due to favorable weather. The number of heating degree days for the first quarter of 2009
was approximately 6% above normal compared to 1% below normal during the same period in 2008.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Operating Expenses.The
decrease was primarily due to:



| |  |  | An approximate $30 million decrease in operating and maintenance expenses primarily due to lower outage and maintenance costs at nuclear and fossil generating plants, lower
management fees from a consolidated affiliate of Duke Energy and lower governance costs, partially offset by increased storm costs primarily driven by a March 2009 snow storm, and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An approximate $8 million decrease in depreciation primarily due to lower depreciation rates, partially offset by additional capital spending.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

PART I



Partially offsetting these decreases was:



| |  |  | An approximate $11 million increase in property and other taxes primarily due to a property tax refund in the first quarter of 2008 and overall higher property and payroll
taxes.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Interest Expense.The increase in interest expense for the three months ended March 31, 2009 compared to the
same period in the prior year was due primarily to increased long-term debt, partially offset by the debt component of AFUDC due to additional capital spending for ongoing construction projects.

Income Tax Expense.Income tax expense for the three months ended March 31, 2009 was flat compared to the same period in the prior year. The effective
tax rate was approximately 34% for both periods.

Other Matters

Duke Energy 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-insured retention on its insurance policy during the second quarter of 2008. Future payments up to the policy limit will be reimbursed by Duke Energys third party insurance carrier. The insurance
policy limit for potential future insurance recoveries for indemnification and medical cost claim payments is $1,074 million in excess of the self insured retention. Insurance recoveries of approximately $1,007 million related to this policy are
classified in the Consolidated Balance Sheets in Other within Investments and Other Assets and Receivables as of March 31, 2009. Duke Energy is not aware of any uncertainties regarding the legal sufficiency of insurance claims. The insurance
company continues to have financial strength ratings as an insurer from major rating agencies that are defined as strong and/or excellent. Based on the foregoing, management believes the insurance recovery asset is probable
of recovery. However, while the insurance carrier is highly rated and appears to be in a strong financial position, it also appears to be exposed, along with many other companies in the insurance industry, to the current credit market situation and
the volatility of the equity and fixed income markets. Other insurance companies have experienced rapid credit rating downgrades and there is no assurance that it will retain its current rating.

Item 4. 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 March 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 March 31, 2009 and have concluded that no change has materially affected, or is reasonably likely to materially affect, internal
control over financial reporting.
