These surcharges will increase as NYSERDA increases its renewables energy purchases.
The NYSPSC issued an order in January 2010 formally increasing the RPS target to 30 percent by 2015 and requiring NYSPSC staff to develop a program to address the geographic balance of the RPS, setting-aside up to $30 million per year to be spent in the downstate region (including in the Utilities’ service territories) until 2015 for this purpose.
Large renewable resources are grid-connected and sell their energy output in the wholesale energy market administered by the NYISO.
As a result of the Utilities participation in the NYISO wholesale markets, a portion of the Utilities’ NYISO energy purchases are sourced from renewable resources.
The energy produced by customer-sited renewables offsets the energy which the Utilities would otherwise have procured, thereby reducing the overall level of non-renewable energy consumed.
In 2008, the NYSPSC issued an order authorizing the Utilities to begin implementing energy efficiency programs.
Costs of the programs will be recovered primarily through a separate non-bypassable charge.
Gas Operations Gas Facilities CECONY’s capitalized costs for utility plant, net of accumulated depreciation, for gas facilities, which are primarily distribution facilities, were $3,153 million and $2,892 million at December 31, 2010 and 2009, respectively.
CECONY’s gas sales and deliveries for the last five years were Natural gas is delivered by pipeline to CECONY at various points in its service territory and is distributed to customers by the company through an estimated 4,340 miles of mains and 385,396 service lines.
The company owns a natural gas liquefaction facility and storage tank at its Astoria property in Queens, New York.
The plant can store approximately 1,000 mdths of which a maximum of about 250 mdths can be withdrawn per day.
The company has about 1,226 mdths of additional natural gas storage capacity at a field in upstate New York, owned and operated by Honeoye Storage Corporation, a corporation 28.8 percent owned by CECONY and 71.2 percent owned by Con Edison Development.
Gas Sales and Deliveries The company generally recovers the cost of the gas that it buys and then sells to its firm sales customers.
It does not make any margin or profit on the gas it sells.
CECONY’s gas revenues are subject to a weather normalization clause and, effective October 2007, a revenue decoupling mechanism.
As a result, its gas delivery revenues are generally not affected by changes in delivery volumes from levels assumed when rates were approve
## Table 0 ##
(a) Includes 3,385, 2,851, 2,955, 2,043 and 462 mdths for 2010, 2009, 2008, 2007 and 2006 respectively, which are also reflected in firm transportation and othe
Part I Item 1 Entergy Corporation, Utility operating companies, and System Energy 196 Louisiana parishes in which it holds non-exclusive franchises.
Entergy Louisiana's electric franchises expire during 2009-2036.
Entergy Mississippi has received from the MPSC certificates of public convenience and necessity to provide electric service to areas within 45 counties, including a number of municipalities, in western Mississippi.
Under Mississippi statutory law, such certificates are exclusive.
Entergy Mississippi may continue to serve in such municipalities upon payment of a statutory franchise fee, regardless of whether an original municipal franchise is still in existence.
Entergy New Orleans provides electric and gas service in the City of New Orleans pursuant to city ordinances (except electric service in Algiers, which is provided by Entergy Louisiana).
These ordinances contain a continuing option for the City of New Orleans to purchase Entergy New Orleans' electric and gas utility properties.
Entergy Texas holds a certificate of convenience and necessity from the PUCT to provide electric service to areas within approximately 24 counties in eastern Texas, and holds non-exclusive franchises to provide electric service in approximately 65 incorporated municipalities.
Entergy Texas typically is granted 50-year franchises.
Entergy Texas' electric franchises expire during 2009-2045.
The business of System Energy is limited to wholesale power sales.
It has no distribution franchises.
Property and Other Generation Resources Generating Stations The total capability of the generating stations owned and leased by the Utility operating companies and System Energy as of December 31, 2008, is indicated below:
## Table 1 ##
(1) "Owned and Leased Capability" is the dependable load carrying capability as demonstrated under actual operating conditions based on the primary fuel (assuming no curtailments) that each station was designed to utilize.
The Entergy System's load and capacity projections are reviewed periodically to assess the need and timing for additional generating capacity and interconnections.
These reviews consider existing and projected demand, the availability and price of power, the location of new load, and the economy.
Summer peak load in the Entergy System service territory has averaged 21,039 MW from 2002-2008.
Due to changing use patterns, peak load growth has nearly flattened while annual energy use continues to grow.
In the 2002 time period, the Entergy System's long-term capacity resources, allowing for an adequate reserve margin, were approximately 3,000 MW less than the total capacity required for peak period demands.
In this time period Entergy met its capacity shortages almost entirely through short-term power purchases in the wholesale spot market.
In the fall of 2002, the Entergy System began a program to add new resources to its existing generation portfolio and began a process of issuing
Borrowing Arrangements We maintain debt levels we consider prudent based on our cash flow, interest coverage ratio and percentage of debt to capital.
We use debt financing to lower our overall cost of capital which increases our return on stockholders’ equity.  ?
In October 2011, we entered into a new five-year agreement establishing an unsecured revolving credit facility to borrow up to $1.1 billion, with an option to increase borrowings by an additional $400 million with the consent of the lenders.
As of December 31, 2012, $1.1 billion was available to borrow under the agreement.
The unsecured revolving credit agreement contains certain financial and other covenants, customary representations, warranties and events of default.
As of December 31, 2012, we complied with all of these covenants.
We may use these funds for general corporate purposes, including commercial paper backstop and business acquisitions.  ?
In addition to the revolving credit facility, we maintain lines of credit with domestic and international commercial banks.
As of December 31, 2012, we could borrow up to approximately $176.7 million in various currencies under the lines of credit and as of December 31, 2011, we could borrow up to $76.9 million.
Registration Statements ?
In May 2009, we filed a shelf registration statement on Form S-3 that registered an indeterminate amount of debt securities.
This registration statement was effective immediately upon filing under Securities and Exchange Commission regulations governing “well-known seasoned issuers” (the “2009 WKSI Registration Statement”).  ?
In November 2011, we issued $250 million of 1.50% Notes due November 1, 2016 and, in December 2010, we issued $350 million of 4.125% Notes due December 1, 2020.
The Notes were issued under the 2009 WKSI Registration Statement.  ?
The 2009 WKSI Registration Statement expired in May 2012.
Accordingly, in May 2012, we filed a new registration statement on Form S-3 to replace the 2009 WKSI Registration Statement.
The registration statement filed in May 2012 registered an undeterminate amount of debt securities effective immediately.  ?
Proceeds from the debt issuances and any other offerings under the registration statement filed in 2012 may be used for general corporate requirements.
These may include reducing existing borrowings; financing capital additions; and funding contributions to our pension plans, future business acquisitions and working capital requirements.
OFF-BALANCE SHEET ARRANGEMENTS, CONTRACTUAL OBLIGATIONS AND CONTINGENT LIABILITIES AND COMMITMENTS As of December 31, 2012, our contractual cash obligations by year were as follows:
## Table 2 ##
In entering into contractual obligations, we have assumed the risk that might arise from the possible inability of counterparties to meet the terms of their contracts.
We mitigate this risk by performing financial assessments prior to contract execution, conducting periodic evaluations of counterparty performance and maintaining a diverse portfolio of qualified counterparties.
As of December 31, 2012, we did not have any material obligations with European financial institutions.
Our risk is limited to replacing the contracts at prevailing market rates.
We do not expect any significant losses resulting from counterparty defaults.
regulatory liabilities are recorded on the balance sheet.
Regulatory assets represent probable future revenues associated with certain costs or liabilities that have been deferred and are expected to be recovered through rates charged to customers.
Regulatory liabilities represent amounts that are expected to be refunded to customers in future rates or amounts that are collected in rates for future costs.
Recovery or refund of regulatory assets and liabilities is based on specific periods determined by the regulators or occurs over the normal operating period of the assets and liabilities to which they relate.
If at any reporting date a previously recorded regulatory asset is no longer probable of recovery, the regulatory asset is reduced to the amount considered probable of recovery with the reduction charged to expense in the reporting period the determination is made.
See Note 5, Regulatory Assets and Liabilities, for more information.
(g) Property, Plant, and Equipment—We record property, plant, and equipment at cost.
Cost includes material, labor, overhead, and both debt and equity components of AFUDC.
Additions to and significant replacements of property are charged to property, plant, and equipment at cost; minor items are charged to other operation and maintenance expense.
The cost of depreciable utility property less salvage value is charged to accumulated depreciation when property is retired.
We record straight-line depreciation expense over the estimated useful life of utility property using depreciation rates approved by the applicable regulators.
Annual utility composite depreciation rates are shown below:
