Overview

Consolidated Edison, Inc. (Con Edison), incorporated in New York State in 1997, is a holding company which owns all of the outstanding common stock of Consolidated Edison Company of New York, Inc. (CECONY), Orange and Rockland Utilities, Inc. (O&R) and the competitive energy businesses. As used in this report, the term the “Companies” refers to Con Edison and CECONY.

CECONY’s principal business operations are its regulated electric, gas and steam delivery businesses. O&R’s principal business operations are its regulated electric and gas delivery businesses. The competitive energy businesses sell electricity to wholesale and retail customers, provide certain energy-related services, and participate in energy infrastructure projects. Con Edison is evaluating additional opportunities to invest in electric and gas-related businesses.

Con Edison’s strategy is to provide reliable energy services, maintain public and employee safety, promote energy efficiency, and develop cost-effective ways of performing its business. Con Edison seeks to be a responsible steward of the environment and enhance its relationships with customers, regulators and members of the communities it serves.

CECONY

Electric

CECONY provides electric service to approximately 3.3 million customers in all of New York City (except part of Queens) and most of Westchester County, an approximately 660 square mile service area with a population of more than nine million.

Gas

CECONY delivers gas to approximately 1.1 million customers in Manhattan, the Bronx and parts of Queens and Westchester County.

Steam

CECONY operates the largest steam distribution system in the United States by producing and delivering more than 23,000 MMlbs of steam annually to approximately 1,760 customers in parts of Manhattan.

O&R

Electric

O&R and its utility subsidiaries, Rockland Electric Company (RECO) and Pike County Power & Light Company (Pike) (together referred to herein as O&R) provide electric service to approximately 0.3 million customers in southeastern New York and in adjacent areas of northern New Jersey and northeastern Pennsylvania, an approximately 1,350 square mile service area.

Table of Contents

Gas

O&R delivers gas to over 0.1 million customers in southeastern New York and adjacent areas of northeastern Pennsylvania.

Competitive Energy Businesses

Con Edison pursues competitive energy opportunities through three wholly-owned subsidiaries: Con Edison Solutions, Con Edison Energy and Con Edison Development. These businesses include the sales and related hedging of electricity to wholesale and retail customers, sales of certain energy-related products and services, and participation in energy infrastructure projects. At December 31, 2010, Con Edison’s equity investment in its competitive energy businesses was $337 million and their assets amounted to $807 million.

In 2008, Con Edison Development and its subsidiary, CED/SCS Newington, LLC, completed the sale of their ownership interests in electricity generating plants with an aggregate capacity of approximately 1,706 MW. See Note U to the financial statements in Item 8.

Utility Regulation

State Utility Regulation

Regulators

The Utilities are subject to regulation by the New York State Public Service Commission (NYSPSC), which under the New York Public Service Law, is authorized to set the terms of service and the rates the Utilities charge for providing service in New York. It also approves the issuance of the Utilities’ securities. It exercises jurisdiction over the siting of the Utilities’ electric transmission lines and approves mergers or other business combinations involving New York utilities. O&R’s New Jersey subsidiary, RECO, is subject to similar regulation by the New Jersey Board of Public Utilities (NJBPU). O&R’s Pennsylvania subsidiary, Pike, is subject to similar regulation by the Pennsylvania Public Utility Commission (PAPUC). The NYSPSC, together with the NJBPU and the PAPUC, are referred to herein as state utility regulators.

Utility Industry Restructuring In New York

In the 1990s, the NYSPSC restructured the electric utility industry in the state. In accordance with NYSPSC orders, the Utilities sold all of their electric generating facilities other than those that also produce steam for CECONY’s steam business (see Electric Operations – Electric Facilities below) and provided all of their customers the choice to buy electricity or gas from the Utilities or other suppliers (see Electric Operations – Electric Sales and Deliveries and Gas Operations – Gas Sales and Deliveries below).

Following adoption of NYSPSC industry restructuring, there were several utility mergers as a result of which substantially all of the electric and gas delivery service in New York State is now provided by one of three investor-owned utility companies – Con Edison, National Grid plc and Iberdrola, S.A. – or one of two state authorities – New York Power Authority (NYPA) or Long Island Power Authority.

Rate Plans

Investor-owned utilities in the United States provide service to customers according to the terms of tariffs approved by the appropriate state utility regulator. The tariffs include schedules of rates for service that are designed to permit the utilities to recover from their customers the approved anticipated costs, including capital costs, of providing service to customers as defined by the tariff. The tariffs implement rate plans, that result from rate orders, settlements, or joint proposals developed during rate proceedings. The utilities’ earnings depend on the rate levels authorized in the rate plans and their ability to operate their businesses in a manner consistent with their rate plans.

The utilities’ rate plans each cover specified periods, but rates determined pursuant to a plan generally continue in effect until a new rate plan is approved by the state utility regulator. In New York, either the utility or the NYSPSC can commence a proceeding for a new rate plan, and a new rate plan filed by the utility will take effect automatically in 11 months unless prior to such time the NYSPSC approves a rate plan.

In each rate proceeding, rates are determined by the state utility regulator following the submission by the utility of testimony and supporting information, which are subject to review by the staff of the regulator. Other parties with an interest in the proceeding can

Table of Contents

also review the utility’s proposal and become involved in the rate case. The review process is overseen by an Administrative Law Judge. After an Administrative Law Judge issues a decision, that generally considers the interests of the utility, the regulatory staff, other parties, and legal requisites, the regulator will issue a rate order. The utility and the regulator’s staff and interested parties may enter into a settlement agreement or joint proposal prior to the completion of this administrative process, in which case the agreement would be subject to approval of the regulator.

For each rate plan, the revenues needed to provide the utility a return on invested capital is determined by multiplying the utilities’ forecasted rate base by the utility’s pre-tax weighted average cost of capital. In general, rate base is the amount of the utility’s net plant, deferred taxes and working capital. The NYSPSC uses a forecast of rate base for the rate year. The weighted average cost of capital is determined based on the forecasted amounts and costs of long-term debt and preferred equity, the forecasted amount of common equity and an allowed return on common equity determined by the state utility regulator. The NYSPSC’s current methodology for determining the allowed return on common equity assigns a one-third weight to an estimate determined from a capital asset pricing model applied to a peer group of utility companies and a two-thirds weight to an estimate determined from a dividend discount model using stock prices and dividend forecasts for a peer group of utility companies.

Pursuant to the Utilities’ rate plans, there generally can be no change to the charges to customers during the respective terms of the rate plans other than for recovery of the costs incurred for energy supply and specified adjustments provided for in the rate plans.

Common provisions of the Utilities’ rate plans may include:

“Recoverable energy cost clauses” that allow the Utilities to recover on a current basis the costs for the energy they supply with no mark-up to their full-service customers.

“Other cost reconciliations” that reconcile pension and other postretirement costs, environmental remediation costs, and certain other costs to amounts reflected in delivery rates for such costs. Utilities generally retain the right to petition for recovery or accounting deferral of extraordinary and material cost increases and provision is sometimes made for the utility to retain a share of cost reductions, for example, property tax refunds.

“Revenue decoupling mechanisms” under which actual energy delivery revenues will be compared, on a periodic basis, with the authorized delivery revenues. The difference is accrued with interest for refund to, or recovery from customers, as applicable.

“Earnings sharing provisions” require the Utilities to defer for customer benefit earnings over specified rates of return on common equity. There is no symmetric mechanism for earnings below specified rates of return on common equity.

“Negative earnings adjustments” for failure to meet certain performance standards relating to service reliability, safety and other matters.

Table of Contents

The following table should be read in conjunction with, and is subject to, the more detailed discussion of the Utilities’ rate plans in Note B to the financial statements in Item 8 (which information is incorporated by reference herein).

Liability for Service Interruptions and Other Non-rate Conditions of Service

The tariff provisions under which CECONY provides electric, gas and steam service limit the company’s liability to pay for damages resulting from service interruptions to circumstances resulting from its gross negligence or willful misconduct.

CECONY’s tariff for electric service provides for reimbursement to electric customers for spoilage losses resulting from service interruptions in certain circumstances. In general, the company is obligated to reimburse affected residential and commercial customers for food spoilage of up to $450 and $9,000, respectively, and reimburse affected residential customers for prescription medicine spoilage losses without limitation on amount per claim. The company’s maximum aggregate liability for such reimbursement for an incident is $15 million. The company is not required to provide reimbursement to electric customers for outages attributable to generation or transmission system facilities or events beyond its control, such as storms, provided the company makes reasonable efforts to restore service as soon as practicable.

Generic Proceedings

The NYSPSC from time to time conducts “generic” proceedings to consider issues relating to all electric and gas utilities operating in New York State. Pending proceedings have included those relating to utilities exiting the service of selling electric energy and gas at retail (including an examination of utilities’ provider of last resort responsibility, the utilities’ vision for the ‘smart grid’, the implementation of energy efficiency and renewable energy programs and consumer protections) and addressing any rate disincentives to the promotion of energy efficiency and distributed generation. The Utilities are typically active participants in such proceedings. The Utilities do not expect that these pending generic proceedings will have a material adverse effect on their financial positions, results of operation or liquidity. In February 2011, the NYSPSC initiated a proceeding to examine the existing mechanisms pursuant to which utilities recover site investigation and remediation costs and possible alternatives. See “Environmental Matters – CECONY” and “Environmental Matters – O&R,” below, and Note G to the financial statements in Item 8.

Federal Utility Regulation

The Federal Energy Regulatory Commission (FERC), among other things, regulates the transmission and wholesale sales of electricity in interstate commerce and the transmission and sale of natural gas for resale in interstate commerce. In addition, the FERC has the authority to impose penalties, which could be substantial, including penalties for the violation of reliability rules. Certain activities of the Utilities and the competitive energy businesses are subject to the jurisdiction of FERC. The Utilities are subject to regulation by the FERC with respect to electric transmission rates and to regulation by the NYSPSC with respect to electric and gas retail commodity sales and local delivery service. As a matter of practice, the NYSPSC has approved delivery service rates that include both distribution and transmission costs.

New York Independent System Operator (NYISO)

The NYISO is a not-for-profit organization that controls and operates most of the electric transmission facilities in New York State, including those of the Utilities, as an integrated system and administers wholesale markets for electricity in New York State. In addition to operating the state’s high voltage grid, the NYISO administers the energy, ancillary services and capacity markets. The New York State Reliability Council (NYSRC) promulgates reliability standards subject to FERC oversight. Pursuant to a requirement that is set annually by the NYSRC, the NYISO requires that entities supplying electricity to customers in New York State have generating capacity (either owned or contracted for) in an amount equal to the peak demand of their customers plus the applicable reserve margin. In addition, the NYISO has determined that entities that serve customers in New York City must have enough capacity that is electrically located in New York City to cover a substantial percentage (currently 80 percent; 81 percent effective May 2011) of the peak demands of their New York City customers. These requirements apply both to regulated utilities such as CECONY and O&R for the customers they supply under regulated tariffs and to companies such as Con Edison Solutions that supply customers on market terms. RECO, O&R’s New Jersey subsidiary, provides electric service in an area that has a different independent system operator – PJM Interconnection LLC (PJM).

Competition

Competition from suppliers of oil and other sources of energy, including distributed generation (such as solar, fuel cells and micro-turbines), may provide alternatives for the Utilities’ delivery customers. See “Rate Agreements” in Note B and “Recoverable Energy Costs” in Note A to the financial statements in Item 8.

The Utilities do not consider it reasonably likely that another company would be authorized to provide utility delivery service of electricity, natural gas or steam where the company already provides service. Any such other company would need to obtain NYSPSC consent, satisfy applicable local requirements, install facilities to provide the service, meet applicable services standards, and charge customers comparable taxes and other fees and costs imposed on the service.

Table of Contents

A new delivery company would also be subject to extensive ongoing regulation by the NYSPSC.

The competitive energy businesses participate in competitive energy supply and services businesses that are subject to different risks than those found in the businesses of the Utilities.

The Utilities

CECONY

CECONY, incorporated in New York State in 1884, is a subsidiary of Con Edison and has no significant subsidiaries of its own. Its principal business segments are its regulated electric, gas and steam businesses.

For a discussion of the company’s operating revenues and operating income for each segment, see “Results of Operations” in Item 7. For additional information about the segments, see Note N to the financial statements in Item 8.

Electric Operations

Electric Facilities

CECONY’s capitalized costs for utility plant, net of accumulated depreciation, for distribution facilities were $12,549 million and $11,824 million at December 31, 2010 and 2009, respectively. For its transmission facilities, the costs for utility plant, net of accumulated depreciation, were $2,150 million and $1,953 million at December 31, 2010 and 2009, respectively, and for its generation facilities, the costs for utility plant, net of accumulated depreciation, were $396 million and $392 million, at December 31, 2010 and 2009, respectively.

Distribution Facilities. CECONY owns 62 area distribution substations and various distribution facilities located throughout New York City and Westchester County. At December 31, 2010, the company’s distribution system had a transformer capacity of 28,997 MVA, with 36,781 miles of overhead distribution lines and 96,324 miles of underground distribution lines. The underground distribution lines represent the single longest underground electric delivery system in the United States. To continue its commitment to upgrade and reinforce its energy delivery infrastructure so that it can continue to safely and reliably meet electric demand, the company added one new substation, Newtown, in Queens in 2010.

Transmission Facilities. The company’s transmission facilities are located in New York City and Westchester, Orange, Rockland, Putnam and Dutchess counties in New York State. At December 31, 2010, CECONY owned or jointly owned 438 miles of overhead circuits operating at 138, 230, 345 and 500 kV and 740 miles of underground circuits operating at 69, 138 and 345 kV. The company’s 38 transmission substations and 62 area stations are supplied by circuits operated at 69 kV and above. In 2011, the company expects to complete a 9 ¹ / 2 mile transmission line connecting its Sprainbrook substation in Westchester County with the new Academy substation being constructed in upper Manhattan.

CECONY’s transmission facilities interconnect with those of National Grid, Central Hudson Gas & Electric Corporation, O&R, Iberdrola USA, Connecticut Light and Power Company, Long Island Power Authority, NYPA and Public Service Electric and Gas Company.

Generating Facilities. CECONY’s electric generating facilities consist of plants located in Manhattan with an aggregate capacity of 698 MW. The company expects to have sufficient amounts of gas and fuel oil available in 2011 for use in these facilities.

Electric Sales and Deliveries

CECONY delivers electricity to its full service customers who purchase electricity from the company. The company also delivers electricity to its customers who purchase electricity from other suppliers through the company’s retail access plan. In addition, the company delivers electricity to state and municipal customers of NYPA and economic development customers of municipal electric agencies.

Table of Contents

The company charges all customers in its service area for the delivery of electricity. The company generally recovers, on a current basis, the cost of the electricity that it buys and then sells to its full-service customers. It does not make any margin or profit on the electricity it sells. Effective April 2008, CECONY’s electric revenues became subject to a revenue decoupling mechanism. As a result, its electric delivery revenues are generally not affected by changes in delivery volumes from levels assumed when rates were approved. CECONY’s electric sales and deliveries, excluding off-system sales, for the last five years were:

For further discussion of the company’s electric operating revenues and its electric results, see “Results of Operations” in Item 7. For additional segment information, see Note N to the financial statements in Item 8.

Electric Peak Demand

The electric peak demand in CECONY’s service area occurs during the summer air conditioning season. The 2010 service area peak demand, which occurred on July 6, 2010, was 12,963 MW. The 2010 peak demand included an estimated 5,815 MW for CECONY’s full-service customers, 5,125 MW for customers participating in its electric retail access program and 2,023 MW for NYPA’s customers and municipal electric agency customers. The NYISO invoked demand reduction programs on July 6, 2010, as it had on peak demand days in some previous years (most recently 2006). “Design weather” for the electric system is a standard to which the actual peak demand is adjusted for evaluation and planning purposes. Since the majority of demand reduction programs are invoked only in specific circumstances, design conditions do not include these programs’ potential impact. However, the CECONY forecasted peak demand at design conditions does include the impact of permanent demand reduction programs. The company estimates that, under design weather conditions, the 2011 service area peak demand will be 13,275 MW, including an estimated 5,735 MW for its full-service customers, 5,450 MW for its electric retail access customers and 2,090 MW for NYPA’s customers and municipal electric agency customers. The company forecasts average annual growth of the peak electric demand in the company’s service area over the next five years at design conditions to be approximately 0.7 percent per year. The company continues to monitor the potential impact on customer demand from the current economic conditions.

Electric Supply

Most of the electricity sold by CECONY to its customers in 2010 was purchased under firm power contracts or through the wholesale electricity market

Table of Contents

administered by the NYISO. Con Edison expects that these resources will again be adequate to meet the requirements of its customers in 2011. The company plans to meet its continuing obligation to supply electricity to its customers through a combination of electricity purchased under contracts, purchased through the NYISO’s wholesale electricity market, or generated from its electricity generating facilities. For information about the company’s contracts for approximately 3,320 MW of electric generating capacity, see Notes I and O to the financial statements in Item 8. To reduce the volatility of its customers’ electric energy costs, the company has contracts to purchase electric energy and enters into derivative transactions to hedge the costs of a portion of its expected purchases under these contracts and through the NYISO’s wholesale electricity market.

CECONY owns generating stations in New York City associated primarily with its steam system. As of December 31, 2010, the generating stations had a combined electric capacity of approximately 698 MW, based on 2010 summer test ratings. For information about electric generating capacity owned by the company, see “Electric Operations – Electric Facilities – Generating Facilities”, above.

In general, the Utilities recover their purchased power costs, including the cost of hedging purchase prices, pursuant to rate provisions approved by the state public utility regulatory authority having jurisdiction. See “Financial and Commodity Market Risks – Commodity Price Risk,” in Item 7 and “Recoverable Energy Costs” in Note A to the financial statements in Item 8. From time to time, certain parties have petitioned the NYSPSC to review these provisions, the elimination of which could have a material adverse effect on the Companies’ financial position, results of operations or liquidity.

In a July 1998 order, the NYSPSC indicated that it “agree(s) generally that CECONY need not plan on constructing new generation as the competitive market develops,” but considers “overly broad” and did not adopt CECONY’s request for a declaration that, solely with respect to providing generating capacity, it will no longer be required to engage in long-range planning to meet potential demand and, in particular, that it will no longer have the obligation to construct new generating facilities, regardless of the market price of capacity. CECONY monitors the adequacy of the electric capacity resources and related developments in its service area, and works with other parties on long-term resource adequacy issues within the framework of the NYISO. In addition, the NYISO has adopted reliability rules that include obligations on transmission owners (such as CECONY) to construct facilities that may be needed for system reliability if the market does not solve a reliability need identified by the NYISO.

In 2009, the then Governor of New York announced a new goal of meeting 45 percent of the State’s electricity needs with energy efficiency or renewable resources by 2015. The goal is to be achieved by reducing electricity consumption by 15 percent, and having 30 percent of the electricity used in New York provided by renewable resources. Establishment of the renewable resources target began in September 2004, when the NYSPSC issued an order establishing a renewable portfolio standard (RPS) which provides that by 2013, 24 percent of the State’s energy needs would come from large renewable facilities (such as wind, hydro, and biomass) and smaller customer-sited renewable generation (limited to solar, fuel cells, and wind farm less than 300 kW in size), and 1 percent would come from green marketing efforts. The NYSPSC agreed with the Utilities that the responsibility for procuring the new renewable resources would rest with the New York State Energy Research and Development Authority (NYSERDA), and not the Utilities. In implementing the RPS for large renewable resources, NYSERDA enters into long-term agreements with developers, and pays the developers renewable premiums based on the facilities’ energy output. For customer-sited resources, NYSERDA provides rebates when customers install eligible renewable technologies. The renewable premiums, rebates, and NYSERDA’s administrative fee are financed through a volumetric charge imposed on the delivery customers of each of the state’s investor-owned utilities. Pursuant to the 2004 NYSPSC order, CECONY billed customers RPS surcharges of $33 million and $32 million in 2010 and 2009, respectively.

Table of Contents

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.

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 approved.

CECONY’s gas sales and deliveries for the last five years were:
