PART I

ITEM 1.  BUSINESS

Overview

Homer City is a Pennsylvania limited partnership with Chestnut Ridge Energy Company as a limited partner with a 99.9 percent interest and Mission Energy Westside Inc. as a general partner with a 0.1 percent interest. Both Chestnut Ridge Energy and Mission Energy Westside are wholly owned subsidiaries of Edison Mission Holdings Co., a wholly owned subsidiary of EME. EME is an indirect wholly owned subsidiary of Edison International. Homer City was formed for the purpose of acquiring, owning and operating three coal-fired electric generating units and related facilities located in Indiana County, Pennsylvania with an aggregate capacity of 1,884 MW, which Homer City collectively refers to as the "Homer City plant," for the purpose of producing electric energy. Homer City acquired the Homer City plant on March 18, 1999 and completed a sale-leaseback of its facilities to third parties in December 2001.

Homer City is a party to a contract with EMMT, an EME subsidiary engaged in asset management and trading activities, under which EMMT sells energy and capacity from the Homer City plant into the wholesale market and provides scheduling and other services. When appropriate market and financial conditions exist, EMMT may also engage in hedging activities for Homer City.

Substantial Doubt that Homer City will Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that Homer City will continue as a going concern. Financial statements prepared on this basis assume the realization of assets and the satisfaction of liabilities in the normal course of business for the 12-month period following the date of these consolidated financial statements.The reduction in energy prices experienced in the fourth quarter of 2011 and into 2012 has adversely impacted cash flow, and Homer City is not expected to be able to generate sufficient cash flow from operations necessary to meet its obligations, including the obligations under the Homer City lease.As described further below under Homer City Lease, it is unlikely that Homer City will continue as a going concern throughout 2012. For discussion of the asset impairment recorded with respect to the Homer City plant, see "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 12—Asset Impairments and Other Charges."

Homer City Lease

During the fourth quarter of 2011, Homer City failed to obtain sufficient interest from market participants necessary to fund the capital needed to make environmental improvements under the current lease arrangement.The estimated cost of installing SO2 and particulate emissions control equipment for Units 1 and 2 of the Homer City plant is expected to be approximately $700 million to $750 million.Homer City does not currently have sufficient capital and does not expect to generate sufficient funds from operations to complete retrofits. Restrictions under the agreements entered into as part of Homer City's 2001 sale-leaseback transaction affect, and in some cases significantly limit or prohibit, Homer City's ability to incur indebtedness or make capital expenditures. Consequently, Homer City's ability to install environmental compliance equipment will be dependent on funding from the owner-lessors or third parties. Homer City is currently engaged in discussions with the owner-lessors regarding the potential for such funding.Homer City expects that the outcome of any such discussions, if successful in providing funding for the Homer City plant, will likely result in Homer City's loss of substantially all beneficial economic interest in and material control of the Homer City plant.Failure to resolve the source of funding of necessary capital expenditures for the Homer City plant could result in Homer City's default under the lease agreements giving rise to remedies for the owner-lessors and secured lease obligation bondholders, which could include foreclosing on the leased assets, the general partner of Homer City, or both. For further discussion of these matters, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations—Management's Overview—Homer City Lease."

Electric Power Industry

The United States electric industry, including companies engaged in providing generation, transmission, distribution and retail sales and service of electric power, has undergone significant deregulation over the last three decades, which has led to increased competition, especially in the generation sector. See further discussion of regulations under "Regulatory Matters."

In areas where ISOs and RTOs have been formed, market participants have open access to transmission service typically at a system-wide rate. ISOs and RTOs may also operate real-time and day-ahead energy and ancillary service markets, which are governed by FERC-approved tariffs and market rules. The development of such organized markets into which independent power producers are able to sell has reduced their dependence on bilateral contracts with electric utilities. In addition, capacity markets in various regional wholesale power markets compensate supply resources for the capability to supply electricity when needed, and demand resources for the electricity they avoid using.

Wholesale Markets

Power generated at the Homer City plant is primarily sold into PJM, an RTO which includes all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia. Sales may also be made into the NYISO, which controls the transmission grid and energy and capacity markets for New York State. Subject to PJM and NYISO transmission availability and reliability considerations, Homer City can transmit up to 1,884 MW from its generating units into NYISO and can deliver up to 1,884 MW into PJM. Homer City does not incur any access or wheeling charges for energy delivered into PJM.

PJM

PJM operates a wholesale spot energy market and determines the market-clearing price for each hour based on bids submitted by participating generators indicating the minimum prices at which a bidder is willing to dispatch energy at various incremental generation levels. PJM requires all load-serving entities and generators, such as Homer City, to maintain prescribed levels of capacity, including a reserve margin, to ensure system reliability. PJM's capacity markets have a single market-clearing price for each capacity zone. In May of each year, PJM conducts an annual capacity auction (RPM) to commit generation, energy efficiency, and demand side resources three years forward, and to provide a long-term pricing signal for the construction of capacity resources.

NYISO

The NYISO operates a competitive, non-discriminatory wholesale power market in New York State in response to the FERC's Open Access Rules and includes bid-based electricity and transmission usage markets. The market-clearing price for NYISO's day-ahead and real-time energy markets is set by supplier generation bids and customer demand bids.

Competition

Homer City is subject to competition from energy marketers, public utilities, government-owned power agencies, industrial companies, financial institutions, and other independent power producers. These companies may have competitive advantages as a result of scale, the location of their generation facilities or other factors. Some of Homer City's competitors have a lower cost of capital than Homer City and, in the case of utilities, may be able to recover fixed costs through rate base mechanisms, allowing them to build, buy and upgrade generation without relying exclusively on market clearing prices to recover their investments.

State and local environmental regulations, particularly those that impose stringent state specific emission limits, could put the Homer City plant at a disadvantage compared with competing power plants operating in nearby states and subject to less stringent state emission limits or to federal emission limits alone. Federal air quality regulations such as CSAPR and the MATS rule will put the Homer City plant at a disadvantage compared with plants utilizing other fuels. Potential future climate change regulations could also put the Homer City plant at a disadvantage compared to power plants utilizing other fuels as well as utilities that may be able to recover climate change compliance costs through rate-base mechanisms. The ability of the Homer City plant to compete can also be affected by future environmental regulations, by governmental and regulatory activities designed to support the construction and operation of power generation facilities fueled by renewable energy sources, and by developments such as shale gas technology that lower the price of other fuels.

Overview of Facilities Under Lease

The business description of Homer City is presented for an understanding of the historical operations of generation from this plant. For a discussion of the status of the Homer City lease, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations—Management's Overview—Homer City Lease."

The Homer City plant is located on a 2,413-acre site approximately 45 miles northeast of Pittsburgh within Indiana County, Pennsylvania. Homer City owns a fee interest in the land and leases the facilities on which the generating units are located pursuant to a sale-leaseback transaction completed in December 2001. As a result of the sale-leaseback transaction, Homer City leased the property on which the generating units are located to the owner lessors through site leases and each owner lessor in turn subleased its undivided ground interest in the property to Homer City through site subleases. The term of the site leases is 45 years from the date of the sale-leaseback, with specified renewal options. The term of the site subleases is 33.67 years, the term of the sale-leaseback financing, and is renewable upon renewal of the Homer City facility leases.

The Homer City plant consists of the generating units, a coal cleaning facility, water supply provided by a 1,800-acre reservoir site known as Two Lick Dam, which is not part of the 2,413-acre site, and associated support facilities. The Homer City generating units benefit from direct transmission access to both PJM and NYISO through seven high voltage lines which interconnect through a switchyard located on the site.

The Homer City units are coal-fired boilers and steam turbine-generator units (referred to as Units 1, 2 and 3 in this annual report). Units 1 and 2 were placed into commercial operation in 1969. Unit 1 has an installed capacity of 620 MW, and Unit 2 has an installed capacity of 614 MW. The Unit 1 and 2 boilers have been retrofitted with low NO_x burners to meet Phase I NO_x 1990 CAA standards. In addition, both boilers have supplemental over-fired air systems to further reduce NOx emissions to satisfy Pennsylvania Title I (ozone) requirements. Selective catalytic reduction units have been installed on Units 1 and 2 for further reduction of NOx emissions.

Unit 3 commenced commercial operation in 1977 and has an installed capacity of 650 MW. The boiler for Unit 3 was originally constructed with low NOx burners which satisfied Phase I NO_x 1990 CAA standards, and a supplemental over-fired air system was installed in 1995 to further reduce NO_x emissions. In addition, a FGD system and a selective catalytic reduction system were installed on Unit 3 in 2001.

These improvements were made to enable the Homer City generating units to comply with Phase II of Title IV of the 1990 CAA regarding SO₂ emissions, the Pennsylvania NO_x allowance regulations and Pennsylvania's response to the US EPA SIP Call regarding NO_x emissions.

Water Supply and Other Support Facilities

The Homer City generating units receive their water supply from Two Lick Creek. The water supply to Two Lick Creek is regulated by releases from Two Lick Dam, which is located approximately eight miles upstream from the Homer City plant and is owned, operated and maintained by Homer City in accordance with a dam safety permit and a drought management plan and related consent order and agreement with the PADEP. These facilities were not sold to third parties as part of the 2001 sale-leaseback transaction. Each of the Homer City generating units has a natural draft-cooling tower.

Other support facilities located on the site include a dry ash disposal area, a coal refuse disposal area, coal receiving and storage facilities and water treatment and pumping facilities.

Interconnection Agreement

Homer City is a party to an interconnection agreement with New York State Electric & Gas Corporation (NYSEG) and Pennsylvania Electric Company (Penelec) to provide interconnection services necessary to interconnect the Homer City plant with NYSEG's and Penelec's transmission systems. Unless terminated earlier in accordance with specified terms, the interconnection agreement will terminate on a date mutually agreed to by Homer City, NYSEG and Penelec. The termination date will not exceed the retirement date of the Homer City units. NYSEG and Penelec have agreed to extend the interconnection services (but not the expiration of the agreement) to modifications, additions or upgrades to, or repowering of the Homer City units. Homer City is required to compensate NYSEG and Penelec for all reasonable costs associated with any modifications, additions or replacements made to NYSEG's or Penelec's interconnection facilities or transmission systems in connection with any modification, addition or upgrade to, or repowering of the Homer City units.

6

Power Sales

Energy and capacity from the Homer City plant are sold under terms, including price, duration and quantity, arranged by EMMT with customers through a combination of bilateral agreements (resulting from negotiations or from auctions), forward energy sales and spot market sales. The Homer City plant is situated in the PJM control area and has direct, high-voltage interconnections to PJM and also to the NYISO. Electric power generated at the Homer City plant is primarily sold into the PJM market. Effective April 1, 2011, EMMT allocated to Homer City the benefit of an arrangement that allows EMMT to deliver a portion of Homer City's power into the NYISO. To the extent this arrangement is not utilized, Homer City's power is delivered into PJM.

Fuel Supply

Homer City's Units 1 and 2 have historically consumed approximately 2.8 million to 3.3 million tons of mid-range sulfur coal per year. Two types of coal are purchased, ready-to-burn and raw coal. Ready-to-burn coal is of the quality that can be burned directly in Units 1 and 2, whereas the raw coal purchased for consumption by Units 1 and 2 must be cleaned in the Homer City coal cleaning facility, which has the capacity to clean up to 5 million tons of coal per year. Unit 3 has historically consumed approximately 1.5 million to 2 million tons of coal per year and can consume either raw or ready-to-burn coal. Coal consumption in the current low natural gas price environment may be lower than the historical range. A wet scrubber FGD system for Unit 3 enables this unit to burn less expensive, higher sulfur coal, while still meeting environmental standards for emission control. In general, the coal purchased for all three units is acquired locally. For additional information, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations—Market Risk Exposures—Commodity Price Risk—Coal Price Risk."

Emission Allowances

The federal Acid Rain Program requires electric generating stations to hold SO₂ allowances sufficient to cover their annual emissions. Pursuant to Pennsylvania's implementation of the CAIR, the Homer City plant is required to hold seasonal and annual NO_x allowances. The CAIR remains in effect until a replacement regulation becomes effective.

CSAPR, like the CAIR, is an allowance-based regulation that provides for emissions trading. Under CSAPR, the amount of actual SO₂ or NO_X emissions from plant operations will need to be matched by a sufficient amount of SO₂ or NO_X allowances that are either allocated or purchased in the open market. SO₂ allowances under the federal Acid Rain Program cannot be used to satisfy the requirements under CSAPR. In December 2011, the United States Court of Appeals for the District of Columbia granted a stay of CSAPR pending completion of its review of the rule's validity. If the stay is lifted and CSAPR becomes effective, Homer City expects that additional SO₂ allowances under CSAPR will be required for the Homer City plant. The availability and market prices for those allowances are uncertain, but the associated costs could be significant. For additional information, see "Environmental Matters and Regulations—Air Quality."

Significant Customers

For a discussion of significant customers, see "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 5. Derivative Instruments and Hedging Activities—Credit Risk."

Insurance

For a discussion of insurance, see "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 8. Commitments and Contingencies—Contingencies—Insurance."

Seasonality

Due to fluctuations in electric demand resulting from warm weather during the summer months and cold weather during the winter months, electric revenues from the Homer City plant normally vary substantially on a seasonal basis. In addition, maintenance outages generally are scheduled during periods of lower projected electric demand (spring and fall), further reducing generation and increasing major maintenance costs which are recorded as an expense when incurred. Accordingly, earnings from the Homer City plant are seasonal and have significant variability from quarter to quarter. Seasonal fluctuations may also be affected by changes in market prices. For further discussion regarding market prices, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations—Market Risk Exposures—Commodity Price Risk—Energy Price Risk."

Regulatory Matters

General

Homer City's operations are subject to extensive regulation. Homer City is subject to energy, environmental and other governmental laws and regulations at the federal, state and local levels in connection with the operation of its facilities, and the use of electric energy, capacity and related products, including ancillary services, from those facilities. In addition, Homer City is subject to the market rules, procedures, and protocols of the markets in which it participates.

Federal Power Act

The FERC has exclusive jurisdiction over the rates, terms and conditions of wholesale sales of electricity and transmission services in interstate commerce (other than transmission that is "bundled" with retail sales), including ongoing, as well as initial, rate jurisdiction.The FERC also has jurisdiction over the sale or transfer of specified assets, including wholesale power sales contracts and generation facilities and, in some cases, jurisdiction over the issuance of securities or the assumption of specified liabilities and some interlocking directorates. Dispositions of Homer City's jurisdictional assets and certain types of financing arrangements may require FERC approval.

Homer City, an exempt wholesale generator (EWG), is subject to the FERC's ratemaking jurisdiction under the Federal Power Act, but has been authorized to sell power at market-based rates to purchasers which are not affiliated electric utility companies as long as the absence of market power is shown. If Homer City were to lose its EWG status, defaults under the covenants in Homer City's agreements could be triggered.

Reliability Standards

NERC establishes and enforces reliability standards for the bulk power system. Homer City believes it has taken appropriate steps to be compliant with current NERC reliability standards that apply to its operations.

Transmission of Wholesale Power

Homer City utilizes power lines owned by others for the transmission of electricity. The prices and other terms and conditions of transmission contracts are regulated by the FERC when the entity providing the transmission service is subject to FERC jurisdiction.

Environmental Matters and Regulations

Legislative and regulatory activities by federal, state, and local authorities in the United States relating to energy and the environment impose numerous restrictions and requirements with respect to the operation of the Homer City plant and affect the timing, cost, design and construction of capital improvements to the Homer City plant as well as the cost of mitigating the environmental impacts of past operations. In addition, as discussed in "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 8. Commitments and Contingencies," the US EPA and others have from time to time involved Homer City in litigation. Additional information about environmental matters affecting Homer City, including projected environmental capital expenditures, is included in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Capital Investment Plan" and "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates and Policies—Impairment of Long-Lived Assets."

Air Quality

The CAA, which regulates air pollutants from mobile and stationary sources, has a significant impact on the operation of the Homer City plant. The CAA requires the US EPA to establish concentration levels in the ambient air for six criteria pollutants to protect public health and welfare. These concentration levels are known as National Ambient Air Quality Standards, or NAAQS. The six criteria pollutants are carbon monoxide, lead, nitrogen dioxide, ozone, particulate matter, and SO₂.

Federal environmental regulations require states to adopt state implementation plans, known as SIPs, for certain pollutants, which detail how the state will attain the standards that are mandated by the relevant law or regulation. The SIPs must be equal to or more stringent than the federal requirements and must be submitted to the US EPA for approval. Each state identifies the areas within its boundaries that meet the NAAQS (attainment areas) and those that do not (non-attainment areas), and must develop a SIP both to bring non-attainment areas into compliance with the NAAQS and to maintain good air quality in attainment areas. If the attainment status of areas changes, states may be required to develop new SIPs that address the changes. The Homer City plant is located in a county that has not attained NAAQS for ozone (affected by NO_x emissions from power plants) and fine particulate matter (affected by SO₂ and NO_x emissions from power plants).

8

Nitrogen Oxide and Sulfur Dioxide

Clean Air Interstate and Cross-State Air Pollution Rules

The CAIR, issued by the US EPA on March 10, 2005, mandated significant reductions in NO_x and SO₂ emission allowance caps under the CAA in 28 eastern states and the District of Columbia. In 2008, the U.S. Court of Appeals for the D.C. Circuit initially vacated the CAIR, but later remanded the CAIR to the US EPA for the issuance of a revised rule. The CAIR remains in effect until a replacement regulation becomes effective.

On July 6, 2011, the US EPA adopted the Cross-State Air Pollution Rule (CSAPR).CSAPR establishes emissions reductions for annual sulfur dioxide (SO₂) emissions and annual and ozone season nitrogen oxide (NO_x) emissions in two phases: a first phase originally scheduled to be effective January 1, 2012 and, in most states subject to the program(including Pennsylvania), a second phase effective January 1, 2014 that requires additional reductions in annual SO₂emissions.

In December 2011, the United States Court of Appeals for the District of Columbia granted a stay of CSAPR pending completion of its review of the rule's validity.Oral argument is scheduled for April 13, 2012, and a court decision is expected during the third quarter of 2012.The court directed the US EPA to continue administering the CAIR until its review is completed.

CSAPR, like the CAIR, is an allowance-based regulation that provides for emissions trading. If the stay is lifted and CSAPR becomes effective, the amount of actual SO₂ or NO_x emissions from plant operations will need to be matched by a sufficient amount of SO₂ or NO_x allowances that are either allocated or purchased in the open market. In connection with CSAPR, the US EPA has, for each phase, established SO₂ and NO_x allowance allocations for each state and each generating unit subject to the regulation, and at the close of the annual or seasonal compliance period, units will need to surrender allowances for each ton of SO₂ and NO_x emitted or face penalties.

With the staying of CSAPR, CAIR SO₂ allowances have been provided and a sufficient supply is available for purchase to permit Homer City to continue operations consistent with 2011 levels. If the stay is lifted, the SO₂ allowances allocated to Homer City in CSAPR Phase I (25,797 tons in 2012 and 2013) would be significantly lower than the amount that would be required based on Homer City's historical emissions. It is unclear at this time whether Homer City would be able to acquire allowances in sufficient quantity to cover its normal operations during Phase I of CSAPR and whether it would be able to pass through the cost of such allowances in the marketplace. Accordingly, despite the stay, Homer City continues to evaluate alternative options, including reduced dispatch and fuel modifications, for complying with Phase I of CSAPR. The cost of allowances, together with possible operational impacts or reductions of output that may be required to comply with Phase I of CSAPR, could have a material effect on Homer City.

Homer City has begun work on designing SO₂ and particulate emissions control equipment for Units 1 and 2 and preparing the site for their installation. The estimated cost of installing SO₂and particulate emissions control equipment for Units 1 and 2of the Homer City plant is expected to be approximately $700 million to $750 million.In order for this emissions control equipment to be operational by early 2014, which is the expected deadline under the currently applicable Federal environmental regulations, the construction process would need to begin in the second quarter of 2012.A contractor for engineering, procurement and construction services has been selected to install and construct the emissions control equipment for the Homer City plant. However, construction of these improvements is dependent upon funding from the owner-lessors or third parties. For further discussion of the Homer City lease and environmental improvements, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations—Management's Overview—Homer City Lease."

Revised NAAQS for SO₂ 

In June 2010, the US EPA finalized the primary NAAQS for SO₂ by establishing a new one-hour standard at a level of 75 parts per billion. In June 2011, Pennsylvania submitted its initial recommended attainment/nonattainment designations in connection with the standard. Pennsylvania recommended designating Indiana County, where the Homer City plant is located, as nonattainment for the SO₂ NAAQS.

Pennsylvania

The Homer City plant was subject to the federal CAIR during 2011 and complied with both the NO_x and SO₂requirements by using existing equipment and purchasing SO₂allowances. Pennsylvania adopted a state version of the CAIR, which the US EPA approved in December 2009. Homer City expects to comply with the Pennsylvania CAIR, which is substantially similar to the federal CAIR as it existed prior to the implementation of CSAPR, in the same manner in which it complies with the federal standards.

9

Mercury/Hazardous Air Pollutants

Mercury and Air Toxics Standards Rule

In December 2011, the US EPA announced the Mercury and Air Toxics Standards (MATS) rule, limiting emissions of hazardous air pollutants (HAPs) from coal- and oil-fired electrical generating units. The rule was published in the Federal Register on February 16, 2012, and becomes effective on April 16, 2012.Homer Citydoes not expect that these standards will require Homer City to make additional capital expenditures beyond those that would be required for compliance with CSAPR Phase II.

Pennsylvania

Pennsylvania currently has no state-level mercury regulations.

Ozone

National Ambient Air Quality Standards

In January 2010, the US EPA proposed a revision to the primary and secondary NAAQS for 8-hour ozone that it had finalized in 2008. The 8-hour ozone standard established in 2008 was 0.075 parts per million. In January 2010, the US EPA proposed establishing a primary 8-hour ozone NAAQS between 0.060 and 0.070 parts per million and a distinct secondary standard to protect sensitive vegetation and ecosystems. In September 2011, President Obama announced that the proposed revision was being withdrawn. The ozone NAAQS established in 2008 remains in place, but the implementation process must be completed before the 0.075 parts-per-million standard can be enforced. The US EPA has indicated that it intends to issue initial area designations of attainment, nonattainment, and unclassifiable areas across the nation in 2012. States will then be required to develop and submit SIPs outlining how compliance with the 2008 NAAQS will be achieved. New primary and secondary ozone standards are expected in 2014.

In December 2011, the US EPA indicated that it intended to designate Indiana County, where the Homer City plant is located, as in attainment with the 2008 NAAQS.

Regional Haze

The regional haze rules under the CAA are designed to prevent impairment of visibility in certain federally designated areas. The goal of the rules is to restore visibility in mandatory federal Class I areas, such as national parks and wilderness areas, to natural background conditions by 2064. Sources such as power plants that are reasonably anticipated to contribute to visibility impairment in Class I areas may be required to install BART or implement other control strategies to meet regional haze control requirements.

Pennsylvania submitted its proposed SIP revisions to the US EPA to address regional haze. Pennsylvania proposed that the existing particulate matter emission limits on the Homer City plant, as well as the plant's participation in the CAIR, would satisfy the BART requirement in that state. Because the CAIR was scheduled to expire on December 31, 2011, the US EPA proposed, on December 30, 2011, a limited disapproval of Pennsylvania's SIP, as well as a Federal Implementation Plan that would allow the Homer City plant's participation in CSAPR to satisfy the BART requirement. It is unclear how the stay of CSAPR will affect the Pennsylvania SIP. Homer City believes that the control measures being undertaken to comply with other environmental regulations will likely satisfy the requirements of these SIPs.

New Source Review Requirements

The NSR regulations impose certain requirements on facilities, such as electric generating stations, if modifications are made to air emissions sources at the facility. Since 1999, the US EPA has pursued a coordinated compliance and enforcement strategy to address NSR compliance issues at the nation's coal-fired power plants. The US EPA has filed an enforcement action against Homer City alleging NSR violations. For further discussion, see "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 8. Commitments and Contingencies—Contingencies."

Coal Combustion Wastes

US EPA regulations currently classify coal ash and other coal combustion residuals as solid wastes that are exempt from hazardous waste requirements. This classification enables beneficial uses of coal combustion residuals, such as for cement production and fill materials. In June 2010, the US EPA published proposed regulations relating to coal combustion residuals that could result in their reclassification. For further discussion see "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 9. Environmental Developments."

10

Climate Change

There have been a number of federal and state legislative and regulatory initiatives to reduce greenhouse gas (GHG) emissions. Any climate change regulation or other legal obligation that would require substantial reductions in GHG emissions or that would impose additional costs or charges for the GHG emissions could significantly increase the cost of generating electricity from fossil fuels, and especially from coal-fired plants, which could adversely affect Homer City's business.

Federal Legislative/Regulatory Developments

In June 2010, the US EPA issued the Prevention of Significant Deterioration (PSD) and Title V Greenhouse Gas Tailoring Rule, known as the "GHG tailoring rule." This regulation generally subjects newly constructed sources of GHG emissions and newly modified existing major sources to the PSD air permitting program beginning in January 2011 (and later, to the Title V permitting program under the CAA); however, the GHG tailoring rule significantly increases the emissions thresholds that apply before facilities are subjected to these programs. The emissions thresholds for CO₂ equivalents in the final rule vary from 75,000 tons per year to 100,000 tons per year depending on the date and whether the sources are new or modified.

Regulation of GHG emissions pursuant to the PSD program could affect efforts to modify the Homer City plant in the future and could subject new capital projects to additional permitting or emissions control requirements that could delay such projects. In December 2010, the US EPA announced that it had entered into a settlement with various states and environmental groups to resolve a long-standing dispute over regulation of GHGs from electrical generating units pursuant to the New Source Performance Standards in the CAA and would propose performance standards for emissions from new and modified power plants and emissions guidelines for existing power plants. The specific requirements will not be known until the regulations are finalized. Since January 2010, the US EPA's Final Mandatory Greenhouse Gas Reporting Rule has required all sources within specified categories, including electric generation facilities, to monitor emissions and to submit annual reports to the US EPA by March 31 of each year. Homer City's 2011 GHG emissions were approximately 9 million metric tons.

Litigation Developments

Litigation alleging that GHG is a public and private nuisance may affect Homer City whether or not it is named as a defendant. The law is unsettled on whether or not this litigation presents questions capable of judicial resolution or political questions that should be resolved by the legislative or executive branches. For further discussion, see "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 9. Environmental Developments."

Employees

At December 31, 2011, Homer City employed 252 employees, approximately 179 of whom are covered by a collective bargaining agreement governing wages, benefits and working conditions. This collective bargaining agreement expires on December 31, 2012.

ITEM 1A.  RISK FACTORS

Liquidity Risks

Homer City is not expected to generate sufficient cash flow from operations necessary to meet its obligations.

At December 31, 2011, Homer City had cash and cash equivalents of $84 million. Homer City is obligated to pay $95 million, $84 million and $98 million of senior rent and $65 million, $65 million and $40 million of equity rent in each of 2012, 2013 and 2014, respectively. Current and forthcoming environmental requirements will require Homer City to install SO₂ and particulate emissions control equipment for Units 1 and 2 at a cost of approximately $700 million to $750 million.

The accompanying consolidated financial statements have been prepared assuming that Homer City will continue as a going concern. Financial statements prepared on this basis assume the realization of assets and the satisfaction of liabilities in the normal course of business for the 12-month period following the date of these consolidated financial statements.The reduction in energy prices experienced in the fourth quarter of 2011 and into 2012 has adversely impacted cash flow, and Homer City is not expected to be able to generate sufficient cash flow from operations necessary to meet its obligations, including the obligations under the Homer City lease. As described further below, it is unlikely that Homer City will continue as a going concern throughout 2012.

During the fourth quarter of 2011, Homer City failed to obtain sufficient interest from market participants necessary to fund the capital needed to make environmental improvements under the current lease arrangement.The estimated cost of installing SO2 and particulate emissions control equipment for Units 1 and 2 of the Homer City plant is expected to be approximately $700 million to $750 million.Homer City does not currently have sufficient capital and does not expect to generate sufficient funds

11

from operations to complete retrofits. Restrictions under the agreements entered into as part of Homer City's 2001 sale-leaseback transaction affect, and in some cases significantly limit or prohibit, Homer City's ability to incur indebtedness or make capital expenditures. Consequently, Homer City's ability to install environmental compliance equipment will be dependent on funding from the owner-lessors or third parties. Homer City is currently engaged in discussions with the owner-lessors regarding the potential for such funding.Homer City expects that the outcome of any such discussions, if successful in providing funding for the Homer City plant, will likely result in Homer City's loss of substantially all beneficial economic interest in and material control of the Homer City plant.Failure to resolve the source of funding of necessary capital expenditures for the Homer City plant could result in Homer City's default under the lease agreements giving rise to remedies for the owner-lessors and secured lease obligation bondholders, which could include foreclosing on the leased assets, the general partner of Homer City, or both. For further discussion, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations—Management's Overview—Homer City Lease."

The interests of EME as Homer City's equity holder may conflict with the interests of holders of debt.

Homer City is indirectly owned and controlled by EME. The directors appointed by EME are able to make decisions affecting Homer City's capital structure which could include, subject to contractual obligations and applicable law, decisions on the ultimate disposition of the Homer City plant. The interests of EME may not in all cases be aligned with the interests of the holders of Homer City's debt. As Homer City addresses its financial difficulties or becomes unable to pay its debts as they mature, the interests of EME might conflict with the interests of holders of Homer City's debt.

Regulatory and Environmental Risks

Homer City is subject to extensive environmental regulation and permitting requirements that may involve significant and increasing costs.

Homer City's operations are subject to extensive and frequently changing environmental regulations with respect to, among other things, air quality, water quality and waste disposal which involve significant and increasing costs and substantial uncertainty. Homer City is required to obtain, and comply with conditions established by, licenses, permits and other approvals in order to construct, operate or modify its facilities. Failure to comply with these requirements could subject Homer City to civil or criminal liability, the imposition of liens or fines, or actions by regulatory agencies seeking to curtail Homer City's operations. Homer City may also be exposed to risks arising from past, current or future contamination at its facilities or with respect to off-site waste disposal sites that have been used in its operations.

Homer City devotes significant resources to environmental monitoring, emissions control equipment and emission allowances to comply with environmental regulatory requirements. Homer City believes that it is currently in substantial compliance with environmental regulatory requirements. However, the US EPA has filed an enforcement action against Homer City alleging violations of the CAA and other regulations at the Homer City plant. For more detail with respect to these matters, see "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 8. Commitments and Contingencies."

The current trend is toward more stringent standards, stricter regulation, and more expansive application of environmental regulations. The adoption of laws and regulations to implement CO₂ controls could adversely affect coal-fired power plants. Other environmental laws, particularly with respect to air emissions, disposal of ash, wastewater discharge and cooling water systems, are also generally becoming more stringent. The continued operation of the Homer City plant is expected to require substantial capital expenditures for environmental controls. If Homer City cannot comply with all applicable regulations, it could be required to retire or suspend operations at its facilities, or restrict or modify the operations of its facilities, and its business, results of operations and financial condition could be adversely affected.

Homer City is required to surrender emission allowances equal to emissions of specific substances in connection with the operation of its facilities. This may require the purchase of allowances, which are subject to price volatility and which could be unavailable.

Typically, environmental laws require a lengthy and complex process for obtaining licenses, permits and approvals prior to construction, operation or modification of a project or generating facility. Homer City cannot provide assurance that it will be able to obtain and comply with all necessary licenses, permits and approvals for the Homer City plant. If there is a delay in obtaining required approvals or permits or if Homer City fails to obtain and comply with such permits, the operation of the Homer City plant may be interrupted or become subject to additional costs.

The controls imposed on the Homer City plant as a result of environmental regulations may require material expenditures or unit shutdowns.

Capital expenditures relating to required environmental controls for the Homer City plant are expected to be significant and could make some units uneconomic to maintain or operate. Homer City may ultimately decide to shut down units rather than

12

making improvements. Unit shutdowns could have an adverse effect on Homer City's business, results of operation and financial condition. For more information about Homer City's plans for environmental compliance, see "Item 1. Business—Environmental Matters and Regulations—Air Quality—Nitrogen Oxide and Sulfur Dioxide," "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations—Management's Overview—Homer City Lease" and "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 9. Environmental Developments."

Homer City is subject to extensive energy industry regulation.

Homer City's operations are subject to extensive regulation by governmental agencies. Federal laws and regulations govern, among other things, transactions by and with purchasers of power, including utility companies, the development and construction of generation facilities, the ownership and operations of generation facilities, and access to transmission. Generation facilities are also subject to federal, state and local laws and regulations that govern, among other things, the geographical location, zoning, land use, and operation of a project. Homer City, in the course of its business, must obtain and periodically renew licenses, permits and approvals for the Homer City plant. The FERC may impose various forms of market mitigation measures, including price caps and operating restrictions, where it determines that potential market power might exist and that the public interest requires mitigation. RTOs and ISOs may impose bidding and scheduling rules, both to curb the potential exercise of market power and to facilitate market functions. Such actions may materially affect Homer City's results of operations. The Homer City plant is also subject to mandatory reliability standards promulgated by NERC, compliance with which can increase the facilities' operating costs or capital expenditures.

This extensive governmental regulation creates significant risks and uncertainties for Homer City's business. Existing regulations may be revised or reinterpreted and new laws and regulations may be adopted or become applicable to Homer City or its facilities or operations in a manner that may have a detrimental effect on its business or result in significant additional costs.

The generation and transmission of electricity are dangerous and involve inherent risks of injury to employees and the general public.

Electricity is dangerous for employees and the general public should they come in contact with power lines or electrical equipment. Injuries caused by such contact can subject Homer City to liability that, despite the existence of insurance coverage, can be significant. Such liabilities could be significant but are very difficult to predict. The range of possible liabilities includes amounts that could adversely affect Homer City's liquidity and results of operations.

Market Risks

Homer City's operations are subject to market risks related to wholesale energy prices because it operates without long-term power purchase agreements. Wholesale energy prices have substantially declined in recent years.

The Homer City plant does not have long-term power purchase agreements. Because the output of the Homer City plant is not committed to be sold under long-term contracts, the plant is subject to market forces which determine the amount and price of energy, capacity and ancillary services sold from the plant. Unlike most other commodities, electric power can only be stored on a very limited basis and generally must be produced when it is to be used. As a result, the wholesale power markets are subject to significant and unpredictable price fluctuations over relatively short periods of time. Due to the volume of sales into PJM from the Homer City plant, Homer City has concentrated exposure to market conditions and fluctuations in PJM. Prices for power and capacity have declined significantly due largely to lower natural gas prices and have been affected in recent years by increased use of demand response technology, changes in final demand for power during the economic slowdown, and technological developments that have increased access to natural gas shale reserves, resulting in substantial declines in market prices for natural gas which supplies power plants that compete with the Homer City plant.

Market prices of energy, capacity and ancillary services sold from the Homer City plant are influenced by multiple factors beyond Homer City's control, and thus there is considerable uncertainty whether or when current depressed prices will recover. Homer City's hedging activities may not cover the entire exposure of its assets or positions to market price volatility, and the level of hedging, which is currently low, will vary over time. The effectiveness of Homer City's hedging activities may depend on the amount of credit available for EMMT to post collateral, either in support of performance guarantees or as cash margin, and liquidity requirements may be greater than Homer City anticipates or will be able to meet. Homer City cannot provide assurance that its hedging strategies will successfully mitigate market risks. For more detail with respect to these matters, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations—Market Risk Exposures—Commodity Price Risk."

13

Homer City's financial results can be affected by changes in fuel prices, fuel transportation cost and interruptions in fuel supply.

In addition to volatile power prices, Homer City's business is subject to changes in fuel costs and fuel transportation costs. Fuel costs are volatile and can be influenced by many factors outside Homer City's control. The price at which Homer City can sell its energy may not rise or fall at the same rate as a corresponding rise or fall in fuel costs. Operations at the Homer City plant are dependent upon the availability and affordability of coal which is available only from a limited number of suppliers. All of these factors may have an adverse effect on Homer City's financial condition and results of operations. For additional information, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations—Market Risk Exposures—Coal Price Risk."

Competition could adversely affect Homer City's business.

Homer City has numerous competitors in all aspects of its business, some of whom may have greater liquidity, greater access to credit and other financial resources, lower cost structures, greater ability to withstand losses, larger staffs or more experience than Homer City. Multiple participants in the wholesale markets, including many regulated utilities, have a lower cost of capital than most merchant generators and often are able to recover fixed costs through rate base mechanisms, allowing them to build, buy and upgrade generation assets without relying exclusively on market clearing prices to recover their investments. These factors could affect Homer City's ability to compete effectively in the markets in which those entities operate. Newer plants owned by Homer City's competitors are often more efficient than the Homer City plant and may also have lower costs of operation. Over time, the Homer City plant may become obsolete in its markets, or be unable to compete with such plants.

Operating Risks

The Homer City plant may be affected by general operating risks and hazards customary in the power generation industry. Homer City may not have adequate insurance to cover all these hazards.

The operation of power generation facilities is a potentially dangerous activity that involves many operating risks, including transmission disruptions and constraints, equipment failures or shortages, and system limitations, degradation and interruption. Homer City's operations are also subject to risks of human performance and workforce capabilities. There can be no assurance that Homer City's insurance will be sufficient or effective under all circumstances or protect against all hazards to which Homer City may be subject or that the insurance proceeds received for any loss of the facilities or any damage to the facilities would be sufficient to permit Homer City to make any payments of rent under the facility leases. Homer City has older facilities that are subject to higher risks of failure or outage.

Due to the current market environment, the minimum insurance coverage specified under the Homer City sale-leaseback documents is not commercially available at reasonable prices. Homer City has obtained a waiver under the participation agreements that permits it to maintain its current insurance coverage through June 1, 2012. Failure to maintain insurance

pursuant to the sale-leaseback documents, absent a waiver, could result in an event of default under the documents, which could have a material adverse effect on Homer City.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

MANAGEMENT'S OVERVIEW

Homer City is a Pennsylvania limited partnership engaged in the business of operating and selling energy and capacity from its three coal-fired electric generating units and related facilities located near Pittsburgh, Pennsylvania with an aggregate capacity of 1,884 MW. Homer City's operating results were significantly lower in 2011 compared to 2010 as a result of lower generation and lower realized energy and capacity prices. Homer City is engaged in discussions with the owner-lessors regarding funding of retrofit expenditures for the Homer City plant that, if successful in providing funding, will likely result in Homer City's loss of substantially all beneficial economic interest in and material control of the Homer City plant. In addition, as discussed below, Homer City recorded significant impairment charges during the fourth quarter of 2011.

Highlights of Operating Results

Homer City had a net loss of $686 million in 2011 compared to net income of $27 million in 2010. The 2011 results included a $295 million after-tax ($478 million pre-tax) charge resulting from the impairment of the property, plant and equipment related to the Homer City plant and the impact of a $344 million valuation allowance on its deferred tax asset position due to the uncertainty of Homer City's ability to realize such tax benefits. The 2011 decrease in earnings, excluding the impairment charge and the deferred tax valuation allowance,was due to lower generation, lower average realized energy and capacity prices, and higher average fuel costs per MWh.

For further discussion of Homer City's impairment charge, see "Critical Accounting Estimates and Policies—Impairment of Long-Lived Assets" and "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 12. Asset Impairments and Other Charges." For further discussion of the deferred tax valuation allowance, see "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 6. Income Taxes."

Homer City's net income decreased $40 million in 2010 compared to 2009. The 2010 decrease in earnings was primarily due to unrealized losses in 2010 compared to unrealized gains in 2009, higher coal costs, lower generation and higher plant maintenance costs in 2010, partially offset by higher capacity revenues. Energy related unrealized losses in 2010 were $20 million compared to unrealized gains of $15 million in 2009. Results in 2010 included the benefit of power hedge contracts entered into during earlier periods at higher prices than current energy prices.

Substantial Doubt that Homer City will Continue as a Going Concern

Homer City's accompanying financial statements have been prepared assuming that it will continue as a going concern, which contemplates realization of assets and the satisfaction of liabilities in the normal course of business for the 12-month period following the date of these financial statements. The reduction in energy prices experienced in the fourth quarter of 2011 and into 2012 has adversely impacted cash flow, and Homer City is not expected to be able to generate sufficient cash flow from operations necessary to meet its obligations, including the obligations under the Homer City lease.As described further below under Homer City Lease, it is unlikely that Homer City will continue as a going concern throughout 2012.

Homer City Lease

Homer City and its indirect parent, EME, engaged a financial advisor and conducted a bidding process to obtain capital funding from third parties during the second half of 2011 to partially finance the installation of the environmental improvements at the Homer City plant. During the fourth quarter of 2011, such efforts failed to obtain sufficient interest from market participants necessary to fund the capital needed to make such improvements under the current lease arrangement. Homer City does not currently have sufficient capital and does not expect to generate sufficient funds from operations to complete retrofits. Restrictions under the agreements entered into as part of Homer City's 2001 sale-leaseback transaction affect, and in some cases significantly limit or prohibit, Homer City's ability to incur indebtedness or make capital expenditures. Consequently, Homer City's ability to install environmental compliance equipment will be dependent on funding from the owner-lessors or third parties. Homer City is currently engaged in discussions with the owner-lessors regarding the potential for such funding. Homer City expects that the outcome of any such discussions, if successful in providing funding for the Homer City plant, will likely result in Homer City's loss of substantially all beneficial economic interest in and material control of the Homer City plant. Failure to resolve the source of funding of necessary capital expenditures for the Homer City plant could result in Homer City's default under the lease agreements giving rise to remedies for the owner-lessors and secured lease obligation bondholders, which could include foreclosing on the leased assets, the general partner of Homer City, or both.

Homer City is currently engaged in discussions with the owner-lessors through General Electric Capital Corporation (GECC), one of the owner participants, regarding the funding of capital improvements at the Homer City plant. Under the existing

17

Homer City sale-leaseback documents, Homer City would be obligated to reimburse GECC for any amount GECC ultimately agrees to fund for these capital improvements. If these discussions are successful, it is expected that an affiliate of GECC will obtain the economic benefit and majority ownership of all the operating assets of Homer City. The transfer of ownership would be effected on a consensual basis. In addition, GECC is currently engaged in discussions with certain of the holders of the secured lease obligation bonds regarding amendments to the terms of the 8.137% Senior Secured Bonds due 2019 and the 8.734% Senior Secured Bonds due 2026, each issued by Homer City Funding LLC.

There is no assurance that an agreement will be reached with the owner-lessors or the existing secured lease obligation bondholders on funding the capital improvements. Homer City is not expected to meet the covenant requirements of its sale-leaseback documents relating to the payment of equity rent at April 1, 2012 and Homer City will be unable to make the required equity rent payment. There is no assurance that subsequent rent payments will be made.Under the sale-leaseback documents,rent payments are comprised of two components, senior rent and equity rent.Senior rent is used exclusively for debt service to secured lease obligation bondholders, while equity rent is paid to the owner-lessors.In order to pay equity rent, among other requirements, Homer City must meet historical and projected senior rent service coverage ratios of 1.7 to 1 (subject to reduction to 1.3 to 1 under certain circumstances).A failure to pay equity rent does not entitle the owner-lessors to foreclose upon Homer City's leasehold interest, but it does result in the suspension of Homer City's ability to make permitted distributions.Moreover, Homer City would be permanently restricted in its ability to make permitted distributions if a failure to pay equity rent when due was not cured within nine months, or even if cured, occurred more than one additional time during the term of the lease.Homer City is not subject to any minimum historical and projected senior rent service coverage ratios except as conditions to distributions and equity rent payments.Also, failure by Homer City to pay equity rent when due in April 2012 could trigger termination of the $48 million senior rent reserve letter of credit.Homer City would then be required to fund the senior rent reserve, and failure to do so could entitle counterparties to seek available remedies under the sale-leaseback documents, including termination or foreclosure upon the leasehold interest. As a result of the expectation that Homer City is likely to lose substantially all beneficial economic interest in and material control of the Homer City plant, Homer City recorded an impairment charge of $478 million for the fourth quarter of 2011. For further discussion, see "Critical Accounting Estimates and Policies—Impairment of Long-Lived Assets" and "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 12. Asset Impairments and Other Charges."

As a result of the financial outlook of Homer City, EMMT has ceased to enter into hedging activities related to future power sales, but continues to enter into spot market energy transactions on behalf of Homer City pursuant to an intercompany agreement. Those transactions are generally back-to-back transactions in which EMMT enters into a transaction with a third party as a principal and then enters into an equivalent transaction with Homer City. In the case of capacity, EMMT has sold Homer City capacity in the annual PJM base residual auctions through May 2015. If Homer City were to default on its obligations to supply capacity, then Homer City would be liable to EMMT, and potentially also to PJM, to supply that capacity, and for refunds of capacity payments received and penalties (equal to the greater of 20% of the capacity payments or $20 per MW-day) under the PJM tariffs if it failed to do so.

¹  Effective April 1, 2011, EMMT allocated to Homer City the benefit of an arrangement that allows EMMT to deliver a portion of Homer City's power into the NYISO. To the extent this arrangement is not utilized, Homer City's power is delivered into PJM.

Reconciliation of Non-GAAP Disclosures and Statistical Definitions

Average Realized Energy Price

The average realized energy price reflects the average price at which energy is sold into the market including the effects of hedges, real-time and day-ahead sales and PJM fees and ancillary services. It is determined by dividing (i) operating revenues less unrealized gains (losses) and other non-energy related revenues by (ii) generation as shown in the table below. Revenues related to capacity sales are excluded from the calculation of average realized energy price.

	Years Ended December 31,

Operating revenues	$	527		$	636		$	663
Less:
Unrealized (gains) losses	(5		)	20			(15		)
Capacity and other revenues	(85		)	(115		)	(89		)

Generation (in GWh)	9,428			11,028			11,446
Average realized energy price/MWh	$	46.38		$	49.04		$	48.85

The average realized energy price is presented as an aid in understanding the operating results of the Homer City plant. Average realized energy price is a non-GAAP performance measure since such statistical measure excludes unrealized gains or losses recorded as operating revenues. Management believes that the average realized energy price is meaningful for investors as this information reflects the impact of hedge contracts at the time of actual generation in period-over-period comparisons or as compared to real-time market prices.

Statistical Definitions

• Equivalent availability reflects the impact of the unit's inability to achieve full load, referred to as derating, as well as outages which result in a complete unit shutdown. The coal plants are not available during periods of planned and unplanned maintenance. The equivalent availability factor is defined as the number of MWh the coal plants are available to

19

generate electricity divided by the product of the capacity of the coal plants (in MW) and the number of hours in the period.

• The capacity factor indicates how much power a unit generated compared to the maximum amount of power that could be generated according to its rating. It is defined as the actual number of MWh generated by the coal plants divided by the product of the capacity of the coal plants (in MW) and the number of hours in the period.

• The load factor indicates how much power a unit generated compared to the maximum amount of power that a unit was available to generate electricity. It is determined by dividing capacity factor by the equivalent availability factor.

• The forced outage rate refers to forced outages and deratings excluding events outside of management's control as defined by NERC. Examples include floods, tornado damage and transmission outages.

Operating Income (Loss)

Operating loss from the Homer City plant was $446 million in 2011 compared to operating income of $165 million in 2010. Operating income decreased$74 million in 2010 compared to 2009. The 2011 decrease in operating income, excluding the $478 million impairment charge previously discussed in "Management's Overview—Highlights of Operating Results," was primarily attributable to lower energy revenues, driven by lower generation and average realized energy prices, lower capacity revenues, and higher plant maintenance costs from outages at Units 1 and 2, partially offset by unrealized gains in 2011 compared to unrealized losses in 2010 related to hedge contracts and lower fuel costs. The decline in fuel costs was primarily due to lower generation, mostly offset by higher coal costs. Coal costs increased due to higher coal prices. The Homer City plant continued to have a high forced outage rate during 2011 partially as a result of the steam pipe rupture on Unit 1 and the related precautionary maintenance on Unit 2.

The 2010 decrease in operating income from 2009 was primarily attributable to unrealized losses in 2010 compared to unrealized gains in 2009 related to hedge contracts, higher coal costs, lower generation, and higher plant operations costs related to scheduled plant outages, partially offset by an increase in capacity revenues. The Homer City plant experienced increased forced outages in 2010 compared to 2009 due to deratings to comply with opacity restrictions and unscheduled outages. Plant maintenance and overhaul related expenses were higher in 2010 due to the deferral of plant outages in 2009. Coal costs increased due to higher coal prices and changes in the mix of ready-to-burn coal and raw coal consumed.

Included in operating revenues were unrealized gains (losses) from hedging activities of $5 million, $(20) million and $15 million for 2011, 2010 and 2009, respectively. Unrealized gains (losses) were primarily attributable to the ineffective portion of hedge contracts at the Homer City plant attributable to changes in the difference between energy prices at the PJM West Hub (the settlement point under forward contracts) and the energy prices at the Homer City busbar (the delivery point where power generated by the Homer City plant is delivered into the transmission system). Included in fuel costs were $9 million, $7 million and $16 million in 2011, 2010 and 2009, respectively, related to the net cost of emission allowances.

For additional discussion, see "Management's Overview—Homer City Lease."

Other Income (Expense)

Interest expense was $122 million, $127 million and $128 million during 2011, 2010 and 2009, respectively. Interest expense primarily relates to the lease financing of the Homer City plant. Interest expense also included $40 million, $38 million and $36 million during 2011, 2010 and 2009, respectively, related to Homer City's subordinated revolving loan agreement with Edison Mission Finance Co. Homer City had higher long-term debt balances during 2011 as compared to 2010 and 2009 on the subordinated revolving loan agreement.

Income Taxes

Homer City's effective tax rates were 29% and 40% in 2010 and 2009, respectively. The effective tax rate for 2011 was not meaningful due to Homer City providing a full valuation allowance against its net deferred tax assets at December 31, 2011. Homer City's effective income tax rate in 2010 and 2009 varied from the federal statutory rate of 35% primarily due to state income taxes and estimated benefits from a federal deduction related to qualified domestic production activities under Section 199 of the Internal Revenue Code. For further discussion, see "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 6. Income Taxes."

On March 15, 2012, Homer City made an election to be treated as a partnership for federal and state income tax purposes. As a result, the income or loss of Homer City will be allocated to the individual partners. Accordingly, on a prospective basis, no recognition will be given to income taxes in Homer City's financial statements and deferred taxes and the related valuation allowance will be eliminated in the first quarter of 2012.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity

The use of Homer City's cash generated from operations is restricted by the sale-leaseback agreements. Under the participation agreements entered into as part of the sale-leaseback transaction, Homer City's ability to enter into specified transactions and to engage in specified business activities, including financing and investment activities, is subject to significant restrictions. These restrictions could affect, and in some cases significantly limit or prohibit, its ability to, among other things, merge, consolidate or sell its assets, create liens on its properties or assets, enter into non-permitted trading activities, enter into transactions with its affiliates, incur indebtedness, create, incur, assume or suffer to exist guarantees or contingent obligations, make restricted payments to its partners, make capital expenditures, own subsidiaries, liquidate or dissolve, engage in non-permitted business activities, sublease its leasehold interests in the facilities or make improvements to the facilities. Accordingly, Homer City's liquidity is substantially based on its ability to generate cash flow from operations. The reduction in energy prices experienced in the fourth quarter of 2011 and into 2012 has adversely impacted cash flow, and Homer City is not expected to be able to generate sufficient cash flow from operations necessary to meet its obligations, including the obligations under the Homer City lease. It is unlikely that Homer City will continue as a going concern throughout 2012. For further discussion, see "—Management's Overview—Homer City Lease" and "Item 1A. Risk Factors—Liquidity Risks."

Capital Investment Plan

Forecasted capital expenditures through 2014 by Homer City are as follows:

(in millions)	2012		2013		2014
Environmental	$	—	$	—	$	—
Plant capital	39		23		14
Total	$	39	$	23	$	14

The capital investment plan set forth above does not include environmental capital expenditures to retrofit the Homer City plant because Homer City does not have the funds for retrofits and has not yet been able to raise capital needed for such retrofits. The funding of Homer City's environmental expenditures will be dependent on external funding. The cost of the SO₂ and particulate emissions control equipment for Units 1 and 2 of the Homer City plant is expected to be approximately $700 million to $750 million. See "Management's Overview—Homer City Lease" for additional discussion.

Plant capital expenditures relate to non-environmental projects such as boiler and turbine controls, major boiler components, coal-cleaning plant refuse disposal and ash disposal. To the extent available, Homer City plans to fund these expenditures with cash on hand or cash generated from operations.

Homer City's use of cash in its bank accounts is limited to specific operating and capital expenditures as set forth in the security deposit agreement executed as part of the sale-leaseback transaction. The amount in certain reserve accounts will be available for payments due on the equity portion of lease rent during specified periods, and in accordance with the sale-leaseback documents, unless there is a default in the payment of the senior portion of lease rent, in which case the amount will be available to pay such senior portion of the lease rent. The release of funds from these restricted cash accounts is permitted, provided Homer City maintains specified reserve balances in accordance with the sale-leaseback documents, no event of default shall have occurred or be continuing and no two failed rent payments shall have occurred. Homer City had $20 million included in restricted deposits at December 31, 2011 related to these reserve accounts.

Cash Flow

At December 31, 2011, Homer City had cash and cash equivalents of $84 million compared to $132 million at December 31, 2010. Net cash provided by operating activities totaled $34 million, $106 million and $151 million in 2011, 2010 and 2009, respectively. The 2011 decrease in net cash provided by operating activities was primarily attributable to lower generation from outages at Units 1 and 2, lower energy and capacity prices, and the timing of cash receipts and disbursements related to working capital items, partially offset by an increase in interest payable to affiliate under the subordinated revolving loan agreement. The 2010 decrease was primarily due to lower net income in 2010, partially offset by changes in derivative assets and liabilities.

Net cash used in financing activities totaled $68 million, $78 million and $74 million in 2011, 2010 and 2009, respectively. In 2011, Homer City borrowed $24 million, net more from its affiliate subordinated revolving loan, and lease financing payments were $14 million higher, as compared to 2010. In 2010, Homer City paid $4 million, net less on its affiliate subordinated revolving loan, and lease financing payments were $8 million higher, as compared to 2009.

22

Net cash used in investing activities primarily related to capital expenditures of $14 million, $18 million and $26 million in 2011, 2010 and 2009, respectively. In 2009, Homer City also had a $10 million receipt from restricted cash related to permitted withdrawals from restricted deposits pursuant to the sale-leaseback agreements.

Credit Ratings

Homer City is not currently rated. Credit ratings for EME and EMMT are as follows:

	Moody's Rating	S&P Rating	Fitch Rating
EME1	Caa1	CCC+	CCC
EMMT	Not Rated	CCC+	Not Rated

¹  Senior unsecured rating.

All the above ratings are on negative outlook. Homer City cannot provide assurance that the current credit ratings above will remain in effect for any given period of time or that one or more of these ratings will not be lowered. Homer City notes that these credit ratings are not recommendations to buy, sell or holdsecurities and may be revised at any time by a rating agency.

Payments Made Under Subordinated Revolving Loan and Tax Payments

The following table summarizes the payments by Homer City under its subordinated revolving loan with Edison Mission Finance Co., a subsidiary of EME, that constitute permitted distributions pursuant to the terms of the sale-leaseback transaction and any payments made pursuant to tax-allocation agreements:

	Years Ended December 31,
(in millions)	2011		2010		2009
Payment of interest	$	—	$	38	$	33
Payment of principal	—		36		42
Subordinated revolving loan payments	—		74		75
Tax payments under tax-allocation agreements	—		—		—
Total payments	$	—	$	74	$	75

For additional information on the tax-allocation agreements, see "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 1. Summary of Significant Accounting Policies—Income Taxes and Tax-Allocation Agreements."

Key Ratio Affecting Distributions

Set forth below is the key ratio required under the lease covenants contained in Homer City's sale-leaseback agreements for the 12 months ended December 31, 2011:

Financial Ratio	Covenant	Actual
Senior rent service coverage ratio	Greater than 1.7 to 1	1.18 to 1

As indicated above, the actual senior rent service coverage ratio of Homer City was below the covenant threshold for the 12 months ended December 31, 2011, and Homer City also did not meet the threshold for the prospective two 12-month periods, which currently precludes Homer City from making distributions, including repayment of certain intercompany loans and from paying the equity portion of the rent payment. For additional information, see "Management's Overview—Homer City Lease."

Sale-Leaseback Restrictions on Distributions

In order to make a distribution, Homer City must be in compliance with the covenants specified in the lease agreements, including the following financial performance requirements measured on the date of distribution.At the end of each quarter, the equity and debt portions of rent then due and payable must have been paid and the senior rent service coverage ratio for the prior 12-month period (taken as a whole and projected for each of the prospective two 12-month periods) must be greater than 1.7 to 1 in order to make the equity portion of the rent payment and other restricted payments.Homer City would be

23

permanently restricted in its ability to make distributions if a failure to pay equity rent when due was not cured within nine months, or even if cured, occurred more than one additional time during the term of the lease.EME has not guaranteed Homer City's obligations under the leases. Homer City is not expected to meet the covenant requirements of its sale-leaseback agreements relating to the payment of equity rent at April 1, 2012, and Homer City will be unable to make the required equity rent payment. There is no assurance that subsequent rent payments will be made. For additional information, see "Management's Overview—Homer City Lease."

Contractual Obligations, Commercial Commitments and Contingencies

Homer City has contractual obligations and other commercial commitments that represent prospective cash requirements. The following table summarizes Homer City's significant contractual obligations as of December 31, 2011:

MARKET RISK EXPOSURES

Introduction

Homer City's primary market risk exposures are associated with the sale of electricity and capacity from, and the procurement of fuel for, its electric generating facilities. These market risks arise from price fluctuations of electricity, capacity, fuel, emission allowances, and transmission rights. Homer City manages these risks in part by using derivative instruments in accordance with established policies and procedures.

Derivative Instruments

Homer City uses derivative instruments to reduce its exposure to market risks that arise from price fluctuations of electricity, capacity, fuel, emission allowances, and transmission rights. For derivative instruments recorded at fair value, changes in fair value are recognized in earnings at the end of each accounting period unless the instrument qualifies for hedge accounting. For derivatives that qualify for cash flow hedge accounting, changes in their fair value are recognized in other comprehensive income until the hedged item settles and is recognized in earnings. However, the ineffective portion of a derivative that qualifies for cash flow hedge accounting is recognized currently in earnings.

Unrealized Gains and Losses

Homer City classifies unrealized gains and losses from derivative instruments (other than the effective portion of derivatives that qualify for hedge accounting) as part of operating revenues. The following table summarizes unrealized gains (losses):

	Years Ended December 31,
(in millions)	2011			2010			2009
Non-qualifying hedges	$	(1	)	$	(1	)	$	1
Ineffective portion of cash flow hedges	6			(19		)	14
Total unrealized gains (losses)	$	5		$	(20	)	$	15

At December 31, 2011, cumulative unrealized gains were immaterial.

Fair Value Disclosures

In determining the fair value of Homer City's derivative positions, Homer City uses third-party market pricing where available. For further explanation of the fair value hierarchy and a discussion of Homer City's derivative instruments, see "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 3. Fair Value Measurements" and "—Note 5. Derivative Instruments and Hedging Activities," respectively.

The net fair value of Homer City's commodity derivative instruments at December 31, 2011 was a $2 million liability. A 10% change in the market price of the underlying commodity at December 31, 2011 would not be material.

Commodity Price Risk

Introduction

Homer City's operations are exposed to commodity price risk, which reflects the potential impact of a change in the market value of a particular commodity. Commodity price risks are actively monitored, with oversight provided by a risk management committee, to ensure compliance with Homer City's risk management policies, through EMMT. Despite this, there can be no assurance that all risks have been accurately identified, measured and/or mitigated.

Energy Price Risk

Energy and capacity from the Homer City plant are sold under terms, including price, duration and quantity, arranged by EMMT with customers through a combination of bilateral agreements (resulting from negotiations or from auctions), forward energy sales and spot market sales. Power is sold into PJM at spot prices based upon locational marginal pricing.

25

The following table depicts the average historical market prices for energy per megawatt-hour at the locations indicated during the past three years:

	24-Hour Average Historical Market Prices1
	2011		2010		2009
PJM West Hub	$	43.57	$	46.56	$	38.75
Homer City Busbar	39.58		39.18		34.27

¹  Energy prices were calculated at the Homer City busbar (delivery point) and the PJM West Hub using historical hourly day-ahead prices as published by PJM or provided on the PJM web-site.

The following table sets forth the forward market prices for energy per megawatt-hour as quoted for sales into the PJM West Hub at December 31, 2011:

	24-Hour Forward Energy Prices1
2012 calendar "strip"2	$	38.85
2013 calendar "strip"2	$	41.26

¹  Energy prices were determined by obtaining broker quotes and information from other public sources relating to the PJM West Hub delivery point.

²  Market price for energy purchases for the entire calendar year.

Forward market prices at the PJM West Hub fluctuate as a result of a number of factors, including natural gas prices, transmission congestion, changes in market rules, electricity demand (which in turn is affected by weather, economic growth, and other factors), plant outages in the region, and the amount of existing and planned power plant capacity. The actual spot prices for electricity delivered by the Homer City plant into these markets may vary materially from the forward market prices set forth in the preceding table.

EMMT engages in hedging activities for the Homer City plant to hedge the risk of future change in the price of electricity. The following table summarizes Homer City's hedge positions for transactions primarily entered into at the PJM West Hub and to a lesser extent at other trading locations (including forward contracts accounted for on the accrual basis) at December 31, 2011 for electricity expected to be generated in 2012:

	2012
MWh (in thousands)	90
Average price/MWh1	$	49.54

¹  The above hedge positions include forward contracts for the sale of power and futures contracts during different periods of the year and the day. Market prices tend to be higher during on-peak periods and during summer months, although there is significant variability of power prices during different periods of time. Accordingly, the above hedge positions are not directly comparable to the 24-hour PJM West Hub prices set forth above.

Capacity Price Risk

Under the RPM, capacity commitments are made in advance to provide a long-term pricing signal for construction of capacity resources. The following table summarizes the status of capacity sales for Homer City at December 31, 2011:

					RPM Capacity Sold in Base Residual Auction			Other Capacity Sales, Net of Purchases2				Aggregate Average Price per MW-day
	Installed Capacity MW	Unsold Capacity1 MW		Capacity Sold MW	MW	Price per MW-day		MW		Average Price per MW-day
January 1, 2012 to May 31, 2012	1,884	(163	)	1,721	1,771	$	110.00	(50	)	$	30.00	$	112.32
June 1, 2012 to May 31, 2013	1,884	(232	)	1,652	1,736	133.37		(84	)	16.46		139.31
June 1, 2013 to May 31, 2014	1,884	(104	)	1,780	1,780	226.15		—		—		221.03		3
June 1, 2014 to May 31, 2015	1,884	(190	)	1,694	1,694	136.50		—		—		136.50

¹  Capacity not sold arises from: (i) capacity retained to meet forced outages under the RPM auction guidelines, and (ii) capacity that PJM does not purchase at the clearing price resulting from the RPM auction.

²  Other capacity sales and purchases, net includes contracts executed in advance of the RPM base residual auction to hedge the price risk related to such auction, participation in RPM incremental auctions and other capacity transactions entered into to manage capacity risks.

³  Includes the impact of a 100 MW capacity swap transaction executed prior to the base residual auction at $135 per MW-day.

Revenues from the sale of capacity from Homer City beyond the periods set forth above will depend upon the amount of capacity available and future market prices either in PJM or nearby markets if Homer City has an opportunity to capture a higher value associated with those markets.

For additional information regarding capacity sold by Homer City, see "Management's Overview—Homer City Lease."

Basis Risk

Sales made from the Homer City plant in the real-time or day-ahead market receive the actual real-time or day-ahead prices, as the case may be, at the Homer City busbar. In order to mitigate price risk from changes in forward spot prices at the Homer City busbar, Homer City may enter into cash settled futures contracts as well as forward contracts with counterparties for energy to be delivered in future periods. Currently, a liquid market for entering into these contracts at the Homer City busbar does not exist. A liquid market does exist at the PJM West Hub. Homer City's hedging activities use this settlement point to enter into hedging contracts. To the extent that, on the settlement date of a hedge contract, spot prices at the relevant busbar are lower than spot prices at the settlement point, the proceeds actually realized from the related hedge contract are effectively reduced by the difference. This is referred to as "basis risk." During 2011, day-ahead prices at the Homer City busbar were lower than those at the PJM West Hub by an average of 9%, compared to 16% during 2010 and 12% during 2009, due to transmission congestion in PJM.

In order to mitigate basis risk, Homer City may purchase financial transmission rights and basis swaps in PJM. A financial transmission right is a financial instrument that entitles the holder to receive the difference between actual day-ahead prices for two delivery points in exchange for a fixed amount.

Coal Price Risk

The Homer City plant purchases coal primarily from mines located near the facilities in Pennsylvania. Coal purchases are made under a variety of supply agreements. The following table summarizes the amount of coal under contract at December 31, 2011 for the following two years:

	2012	2013
Amount of Coal Under Contract in Millions of Equivalent Tons1	3.3	0.8

¹  The amount of coal under contract in equivalent tons is calculated based on contracted tons and applying a 13,000 Btu equivalent.

Homer City is subject to price risk for purchases of coal that are not under contract. Market prices of NAPP coal, which are related to the price of coal purchased for the Homer City plant, increased during the past two years. The market price of NAPP coal based on 13,000 Btu per pound heat content and <3.0 pounds of SO₂per MMBtu sulfur content was $73.30 per ton at December 30, 2011, compared to a price of $70 per ton and $52.50 per ton at December 31, 2010 and 2009, respectively, as

27

reported by the EIA. In 2011, the price of NAPP coal ranged from $70 per ton to $78.20 per ton, as reported by the EIA. The 2011 increase in NAPP coal prices was primarily driven by the export market demand and global coal pricing.

Based on Homer City's anticipated coal requirements in excess of the amount under contract, Homer City expects that a 10% change in the price of coal at December 31, 2011 would increase or decrease 2012 pre-tax income by approximately $4 million.

Emission Allowances Price Risk

If CSAPR becomes effective as issued, the amount of SO₂ that a plant emits in its operation will need to be matched by a sufficient amount of SO₂ allowances designated under this program (CSAPR SO₂ allowances) that are either allocated to the plant under the CSAPR program or purchased in the open market. SO₂ allowances under the federal Acid Rain Program cannot be used to satisfy the requirements under CSAPR. For additional information on CSAPR, see "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 9. Environmental Developments—Cross-State Air Pollution Rule."

Credit Risk

For further information related to credit risk and how Homer City manages credit risk, see "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 5. Derivative Instruments and Hedging Activities."

Interest Rate Risk

Homer City has mitigated the risk of interest rate fluctuations by obtaining fixed rate financing on its subordinated revolving loan with Edison Mission Finance. Homer City does not believe that interest rate fluctuations will have a material adverse effect on its financial position or results of operations.

CRITICAL ACCOUNTING ESTIMATES AND POLICIES

Introduction

The accounting policies described below are considered critical to obtaining an understanding of Homer City's financial statements because their application requires the use of significant estimates and judgments by management in preparing Homer City's financial statements. Management estimates and judgments are inherently uncertain and may differ significantly from actual results achieved. Management considers an accounting estimate to be critical if the estimate requires significant assumptions and changes in the estimate or if different estimates that could have been selected had been used could have a material impact on Homer City's results of operations or financial position. For more information on Homer City's accounting policies, see "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 1. Summary of Significant Accounting Policies."

Impairment of Long-Lived Assets

Nature of Estimates Required.    Long-lived assets, including intangible assets, are evaluated for impairment in accordance with applicable authoritative guidance. Authoritative guidance requires that if the undiscounted expected future cash flow from a company's assets or group of assets (without interest charges) is less than its carrying value, asset impairment must be recognized on the financial statements. The impairment charges, if applicable, are calculated as the excess of the asset's carrying value over its fair value, which represents the discounted expected future cash flows attributable to the asset or, in the case of assets expected to be sold, at fair value less costs to sell. Long-lived assets are evaluated for impairment whenever indicators exist or when there is a commitment to sell or dispose of the asset. These evaluations may result from significant decreases in the market price of an asset, a significant adverse change in the extent or manner in which an asset is being used in its physical condition, a significant adverse change in legal factors or in the business climate that could affect the value of an asset, as well as economic or operational analyses.

Key Assumptions and Approach Used.    The assessment of impairment requires significant management judgment to determine: (1) if an indicator of impairment has occurred, (2) the forecast of undiscounted expected future cash flow over the asset's estimated useful life to determine if an impairment exists, and (3) if an impairment exists, the fair value of the asset or asset group. Factors that are considered important, which could trigger an impairment, include operating losses, projected future operating losses, the financial condition of counterparties, or significant negative industry or economic trends. The determination of fair value requires management to apply judgment in: (1) estimating future prices of energy and capacity in wholesale energy markets and fuel prices that are susceptible to significant change, (2) environmental and maintenance expenditures, and (3) the time period due to the length of the estimated remaining useful lives.

In preparing long-term cash forecasts, Homer City includes assumptions about future prices for electricity, capacity, fuel and related products and services, as applicable, future operations and maintenance costs and future capital expenditure requirements under different scenarios. As appropriate, Homer City uses a probability weighted approach when determining whether impairment indicators exist. Assumptions included in the long-term cash flow forecasts for merchant projects include:

• Observable market prices for electricity, fuel and related products and services to the extent available and long-term prices developed based on a fundamental price model;

• Long-term capacity prices based on the assumption that capacity markets would continue consistent with their current structure, with expected increases in revenues as a result of declines in reserve margins beyond the price of the latest auctions;

• Trends for additions and retirements for generation resources; and

• Plans for compliance with both existing and possible future environmental regulations.

Homer City includes allocated acquired emission allowances as part of its power plant asset group. Homer City's unit of account is at the plant level and, accordingly, the closure of one of Homer City's units would not result in an impairment of property, plant and equipment unless such condition were to affect an impairment assessment on the entire plant.

Effect if Different Assumptions Used.    The estimates and assumptions used to determine whether an impairment exists are subject to a high degree of uncertainty. The estimated fair value of an asset would change materially if different estimates and assumptions were used to determine the amounts or timing of future revenues, environmental compliance costs or operating expenditures.

Effect on 2011 Results.    As described in "Management's Overview," Homer City failed to obtain sufficient interest from market participants to fund the capital improvements during the process undertaken in the fourth quarter of 2011, and Homer

29

City is currently engaged in discussions with the owner-lessors regarding the potential for such funding.Homer City expects that the outcome of any such discussions, if successful in providing funding for the Homer City plant, will likely result in Homer City's loss of substantially all beneficial economic interest in and material control of the Homer City plant.Failure to resolve the source of funding of necessary capital expenditures for the Homer City plant could result in Homer City's default under the lease agreements giving rise to remedies for the owner-lessors and secured lease obligation bondholders, which could include foreclosing on the leased assets, the general partner of Homer City, or both. In connection with the preparation of its year-end financial statements, Homer City concluded that these events, combined with the current and projected financial condition of Homer City, were indicators of impairment. The long-lived asset group subject to the impairment evaluation was determined to include Homer City's property, plant and equipment.Homer City concluded that the future undiscounted cash flows were insufficient to recover the carrying amount of the asset group.To measure the amount of impairment loss, the income approach was considered the most relevant and resulted in a fair value of $1,085 million.Discounted cash flow analysis based on estimates of future energy, capacity and coal prices and operations and maintenance costs along with the estimated costs of constructing the environmental control equipment was the technique utilized to determine fair value. Accordingly, Homer City recorded an impairment charge of $478 million for the fourth quarter of 2011.

Derivatives

Homer City uses derivative instruments to manage exposure to changes in electricity, fuel oil and interest rates. Derivative instruments that do not meet the normal purchases and sales exception at fair value are recorded with changes in the derivative's fair value recognized currently in earnings unless specific hedge accounting criteria are met. For derivatives that qualify for cash flow hedge accounting treatment, the effective portion of the changes in the derivative's fair value is recognized in other comprehensive income until the hedged item is recognized in earnings.

Management's judgment is required to determine if a transaction meets the definition of a derivative and, if it does, whether the normal purchases and sales exception applies or whether individual transactions qualify for hedge accounting treatment. Management's judgment is also required to determine the fair value of derivative transactions.

Key Assumptions and Approach Used.    Homer City determines the fair value of derivative instruments based on forward market prices in active markets adjusted for nonperformance risk. If quoted market prices are not available, internally developed models are used to determine the fair value. When actual market prices, or relevant observable inputs are not available, it is appropriate to use unobservable inputs which reflect management assumptions, including extrapolating limited short-term observable data and developing correlations between liquid and non-liquid trading hubs. In assessing nonperformance risks, Homer City reviews credit ratings of counterparties (and related default rates based on such credit ratings) and prices of credit default swaps. The market price (or premium) for credit default swaps represents the price that a counterparty would pay to transfer the risk of default, typically bankruptcy, to another party. A credit default swap is not directly comparable to the credit risks of derivative contracts, but provides market information of the related risk of nonperformance.

In addition, a fair value hierarchy is established that prioritizes the inputs to valuation techniques used to measure fair value. For further information, see "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 3. Fair Value Measurements."

Effect if Different Assumptions Used.    As described above, fair value is determined using a combination of market information or observable data and unobservable inputs which reflect management's assumptions. Changes in observable data and unobservable inputs would impact results.

For Homer City's derivative instruments that are measured at fair value using quantitative pricing models, a significant change in estimate could affect Homer City's results of operations. For further sensitivities in Homer City's assumptions used to calculate fair value, see "Market Risk Exposures—Derivative Instruments—Fair Value Disclosures." For further information on derivative instruments, see "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 5. Derivative Instruments and Hedging Activities."

Income Taxes

Nature of Estimates Required.    As part of the process of preparing its financial statements, Homer City is required to estimate its income taxes for each jurisdiction in which it operates. This process involves estimating actual current period tax expense together with assessing temporary differences resulting from differing treatment of items, such as depreciation, for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within Homer City's balance sheets. Homer City records a deferred tax asset valuation allowance when it is more likely than not that all or a portion of its deferred tax assets will not be realized.

30

Homer City takes certain tax positions it believes are applied in accordance with the applicable tax laws. However, these tax positions are subject to interpretation by the Internal Revenue Service, state tax authorities and the courts. Homer City determines its uncertain tax positions in accordance with the authoritative guidance.

Key Assumptions and Approach Used.    Accounting for tax obligations requires management judgment. Management uses judgment in determining whether the evidence indicates it is more likely than not, based solely on the technical merits, that a tax position will be sustained and to determine the amount of tax benefits to be recognized. Judgment is also used in determining the likelihood a tax position will be settled and possible settlement outcomes. Management must also assess the likelihood that Homer City's deferred tax assets will be recovered from future taxable income or the utilization of losses through a reduction in the loan with Edison Mission Finance. In assessing its uncertain tax positions, Homer City considers, among others, the following factors: the facts and circumstances of the position, regulations, rulings, and case law, opinions or views of legal counsel and other advisers, and the experience gained from similar tax positions. Management evaluates uncertain tax positions at the end of each reporting period and makes adjustments when warranted based on changes in fact or law.

Effect if Different Assumptions Used.    Actual income taxes may differ from the estimated amounts which could have a significant impact on the liabilities, revenues and expenses recorded in the financial statements. Homer City continues to be under audit or subject to audit for multiple years in various jurisdictions. Significant judgment is required to determine the tax treatment of particular tax positions that involve interpretations of complex tax laws. A tax liability has been recorded with respect to tax positions in which the outcome is uncertain and the effect is estimable. Such liabilities are based on judgment and a final determination could take many years from the time the liability is recorded and the related filing position is no longer subject to review. Furthermore, settlement of tax positions included in open tax years may be resolved by compromises of tax positions based on current factors and business considerations that may result in material adjustments to income taxes previously estimated.

Effect on 2011 Results.    After assessing the realization of its net deferred tax assets, management believes it is more likely than not that it will not be able to realize the tax benefits from any of its net deferred tax assets and, therefore, recorded a valuation allowance of $344 million during the fourth quarter of 2011. For further discussion, see "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 6. Income Taxes."

Accounting for Contingencies, Guarantees and Indemnities

Nature of Estimates Required.    Homer City records loss contingencies when it determines that the outcome of future events is probable of occurring and when the amount of the loss can be reasonably estimated. When a guarantee or indemnification subject to authoritative guidance is entered into, Homer City records a liability for the estimated fair value of the underlying guarantee or indemnification. Gain contingencies are recognized in the financial statements when they are realized.

Key Assumptions and Approach Used.    The determination of a reserve for a loss contingency is based on management judgment and estimates with respect to the likely outcome of the matter, including the analysis of different scenarios. Liabilities are recorded or adjusted when events or circumstances cause these judgments or estimates to change. In assessing whether a loss is a reasonable possibility, Homer City may consider the following factors, among others: the nature of the litigation, claim or assessment, available information, opinions or views of legal counsel and other advisors, and the experience gained from similar cases. Homer City provides disclosures for material contingencies when there is a reasonable possibility that a loss or an additional loss may be incurred. Some guarantees and indemnifications could have a significant financial impact under certain circumstances, and management also considers the probability of such circumstances occurring when estimating the fair value.

Effect if Different Assumptions Used.    Actual amounts realized upon settlement of contingencies may be different than amounts recorded and disclosed and could have a significant impact on the liabilities, revenues and expenses recorded on the financial statements. In addition, for guarantees and indemnities actual results may differ from the amounts recorded and disclosed and could have a significant impact on Homer City's financial statements. For a discussion of contingencies, guarantees and indemnities, see "Item 8. EME Homer City Generation L.P. Notes to Financial Statements—Note 8. Commitments and Contingencies—Guarantees and Indemnities," "—Contingencies" and "Item 1. Business—Environmental Matters and Regulations."

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the General Partner of EME Homer City Generation L.P.:

In our opinion, the financial statements listed in the index appearing under Item 8 present fairly, in all material respects, the financial position of EME Homer City Generation L.P. at December 31, 2011 and 2010, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2011 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Partnership's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

The financial statements listed in the index appearing under Item 8 have been prepared assuming that the Partnership will continue as a going concern. As discussed in Note 1 to the financial statements, the Partnership does not expect to generate sufficient capital from operations necessary to meet its obligations, which raises substantial doubt on its ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

EME HOMER CITY GENERATION L.P.

NOTES TO FINANCIAL STATEMENTS

Note 1. Summary of Significant Accounting Policies

EME Homer City Generation L.P. (Homer City) is a Pennsylvania limited partnership between Chestnut Ridge Energy Company, as a limited partner with a 99.9 percent interest, and Mission Energy Westside Inc., as a general partner with a 0.1 percent interest. Both Chestnut Ridge Energy and Mission Energy Westside are wholly owned subsidiaries of Edison Mission Holdings Co., a wholly owned subsidiary of Edison Mission Energy (EME). EME is an indirect wholly owned subsidiary of Edison International. The partnership was formed for the purpose of acquiring, owning or leasing and operating three coal-fired electric generating units, and related facilities, which is referred to as the "Homer City plant," located near Pittsburgh, Pennsylvania for the purpose of producing electric energy.

Homer City derives revenues from the sale of energy, capacity and ancillary services into PJM and from bilateral contracts with power marketers and load-serving entities within PJM. Homer City has a contract with Edison Mission Marketing & Trading, Inc. (EMMT), a marketing affiliate, to sell energy, capacity and ancillary services from the Homer City plant, which enables this marketing affiliate to engage in forward sales and hedging transactions to manage electricity price exposure.

On December 7, 2001, Homer City completed a sale-leaseback of the Homer City plant to third-party lessors for an aggregate purchase price of $1.591 billion, made up of $782 million in cash and assumption of debt (the fair value of which was $809 million). This transaction has been accounted for as a lease financing for accounting purposes.

Substantial Doubt that Homer City will Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that Homer City will continue as a going concern. Financial statements prepared on this basis assume the realization of assets and the satisfaction of liabilities in the normal course of business for the 12-month period following the date of these consolidated financial statements.The reduction in energy prices experienced in the fourth quarter of 2011 and into 2012 has adversely impacted cash flow, and Homer City is not expected to be able to generate sufficient cash flow from operations necessary to meet its obligations, including the obligations under the Homer City lease.As described further below under Homer City Lease, it is unlikely that Homer City will continue as a going concern throughout 2012. For discussion of the asset impairment recorded with respect to the Homer City plant, see Note 12—Asset Impairments and Other Charges.

Homer City Lease

During the fourth quarter of 2011, Homer City failed to obtain sufficient interest from market participants necessary to fund the capital needed to make environmental improvements under the current lease arrangement.The estimated cost of installing SO2 and particulate emissions control equipment for Units 1 and 2 of the Homer City plant is expected to be approximately $700 million to $750 million.Homer City does not currently have sufficient capital and does not expect to generate sufficient funds from operations to complete retrofits. Restrictions under the agreements entered into as part of Homer City's 2001 sale-leaseback transaction affect, and in some cases significantly limit or prohibit, Homer City's ability to incur indebtedness or make capital expenditures. Consequently, Homer City's ability to install environmental compliance equipment will be dependent on funding from the owner-lessors or third parties. Homer City is currently engaged in discussions with the owner-lessors regarding the potential for such funding.Homer City expects that the outcome of any such discussions, if successful in providing funding for the Homer City plant, will likely result in Homer City's loss of substantially all beneficial economic interest in and material control of the Homer City plant.Failure to resolve the source of funding of necessary capital expenditures for the Homer City plant could result in Homer City's default under the lease agreements giving rise to remedies for the owner-lessors and secured lease obligation bondholders, which could include foreclosing on the leased assets, the general partner of Homer City, or both. For further discussion with respect to the lease obligations, see Note 8—Commitments and Contingencies—Lease Commitments.

Basis of Presentation

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires Homer City to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

39

Cash Equivalents

Cash equivalents included money market funds totaling $28 million and $31 million at December 31, 2011 and 2010, respectively. The carrying value of cash equivalents equals the fair value as all investments have maturities of less than three months.

Restricted Deposits

Certain cash balances are restricted to pay amounts required for lease payments and provide collateral. Included in restricted deposits were $20 million at each of December 31, 2011 and 2010 related to lease payments, and $7 million at each of December 31, 2011 and 2010 for collateral related to an environmental bond. For additional information regarding the lease payments, see Note 8—Commitments and Contingencies—Lease Commitments—Facilities Sale-Leaseback.

Inventory

Inventory is stated at the lower of weighted-average cost or market. Inventory is recorded at actual cost when purchased and then expensed at weighted-average cost as used. Cost is reduced to market value if the market value of inventory has declined and it is probable that revenues earned from the generation of power will not cover the cost of the inventory in the ordinary course of business or if the inventory is determined to be obsolete. Inventory consisted of the following:

	December 31,
(in millions)	2011		2010
Coal, fuel oil and other raw materials	$	68	$	76
Spare parts, materials and supplies	37		33
Total inventory	$	105	$	109

Purchased Emission Allowances

Purchased emission allowances are stated at the lower of weighted-average cost or market. Purchased emission allowances are recorded at cost when purchased and then expensed at weighted-average cost as used. Cost is reduced to market value if the market value of emission allowances has declined and it is probable that revenues earned from the generation of power will not cover the amounts recorded in the ordinary course of business. Purchased emission allowances are classified as current or long-term assets based on the time the allowances are expected to be used. Emission allowances do not have a pre-determined contractual term or expiration date.

Property, Plant and Equipment

Property, plant and equipment are stated at cost. As part of the acquisition of the Homer City plant, Homer City acquired emission allowances under the United States Environmental Protection Agency's (US EPA's) Acid Rain Program. Homer City uses these emission allowances in the normal course of its business to generate electricity and has classified them as part of property, plant and equipment. Depreciation and amortization are computed on a straight-line basis over the following estimated useful lives:

Plant and equipment under lease financing	33.67 years
Leasehold improvements	Shorter of life of lease or estimated useful life
Emission allowances	33.67 years
Equipment, furniture and fixtures	3 to 7 years

Certain major pieces of Homer City's equipment require periodic repairs and maintenance. These costs, including major maintenance costs, are expensed as incurred.

Impairment of Long-Lived Assets

Homer City evaluates the impairment of its long-lived assets based on a review of estimated future cash flows expected to be generated whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Homer City's unit of account is at the plant level. If the carrying amount of a long-lived asset exceeds the expected future cash flows, undiscounted and without interest charges, then an impairment loss is recognized for the excess of the carrying amount over fair value. Fair value is determined via market, cost and income based valuation techniques, as appropriate. For further discussion, see Note 12—Asset Impairments and Other Charges.

40

Revenue Recognition

Generally, revenues and related costs are recognized when electricity is generated or services are provided unless the transaction is accounted for as a derivative and does not qualify for the normal purchases and sales exception. Homer City enters into power and fuel hedging and optimization transactions under a contract with EMMT. These transactions are executed primarily through the use of physical forward commodity purchases and sales and financial commodity swaps and options. With respect to its physical forward contracts, Homer City takes title to the commodities, and assumes the risks and rewards of ownership. Homer City records the settlement of non-trading physical forward contracts on a gross basis. Homer City nets the cost of purchased power against related third-party sales in markets that use locational marginal pricing, currently PJM. Financial swap and option transactions are settled net and, accordingly, Homer City does not take title to the underlying commodity. Therefore, gains and losses from settlement of financial swaps and options are recorded net in operating revenues in the accompanying statements of operations.

Derivative Instruments and Hedging Activities

Authoritative guidance on derivatives and hedging establishes accounting and reporting standards for derivative instruments (including certain derivative instruments embedded in other contracts). Homer City is required to record derivatives on its balance sheets as either assets or liabilities measured at fair value unless otherwise exempted from derivative treatment as normal purchases and sales. All changes in the fair value of derivative instruments are recognized currently in earnings, unless specific hedge criteria are met, which requires that Homer City formally document, designate, and assess the effectiveness of transactions that receive hedge accounting.

The accounting guidance for cash flow hedges provides that the effective portion of gains or losses on derivative instruments designated and qualifying as cash flow hedges be reported as a component of other comprehensive loss and be reclassified into earnings in the same period during which the hedged forecasted transaction affects earnings. The remaining gains or losses on the derivative instruments, if any, must be recognized currently in earnings.

Where Homer City's derivative instruments are subject to a master netting agreement and the criteria of authoritative guidance are met, Homer City presents its derivative assets and liabilities on a net basis on its balance sheets. The results of derivative activities are recorded in cash flows from operating activities on the statements of cash flows. Derivative and hedging accounting policies are discussed further in Note 5—Derivative Instruments and Hedging Activities.

Income Taxes and Tax-Allocation Agreements

Homer City has historically made an election to be taxed as a corporation for federal and California state tax purposes. Homer City is included in the consolidated federal and state income tax returns of Edison International and is party to a tax-allocation agreement with its indirect parent, Edison Mission Holdings Co. In accordance with the agreement and the tax-allocation procedures in effect, its current tax liability or benefit is generally determined on a separate return basis, except for calculating consolidated state income taxes, for which Homer City uses the state tax apportionment factors of the Edison International group. Also, while Homer City is generally subject to separate return limitations for net losses, under the tax-allocation agreement it is permitted to transfer to Edison Mission Holdings, or its subsidiaries, net operating loss benefits which would not yet be realized in a separate return in exchange for a reduction in Homer City's intercompany account balances (including the subordinated revolving loan). Homer City also has the option, at Homer City's discretion, under its tax-allocation agreement with Edison Mission Holdings to settle federal and state income tax liabilities under the tax-allocation agreement through an increase in indebtedness under the subordinated revolving loan. In 2011 and 2010, Homer City elected its option and settled $1 million and $32 million, respectively, of intercompany tax liabilities through the subordinated revolving loan. Homer City also files a separate state income tax return in Pennsylvania. Amounts included in due to affiliates on the balance sheet associated with this tax-allocation agreement totaled $2 million and $4 million at December 31, 2011 and 2010, respectively.

Homer City accounts for deferred income taxes using the asset-and-liability method, wherein deferred tax assets and liabilities are recognized for future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities using enacted income tax rates. In assessing the realization of Homer City's deferred tax assets, management considered whether it is more likely than not that the deferred tax assets will be realized. Realization of Homer City's deferred tax assets depends upon its ability to generate taxable income in the future or utilize losses through a reduction in the loan with Edison Mission Finance. On a quarterly basis, management evaluates the recoverability of its deferred tax assets to ensure there is adequate support for the realization of the deferred tax assets. In the event management were to determine that Homer City would not be able to realize all or part of its net deferred tax assets in the future, an adjustment to the deferred tax assets would be charged as a reduction to income in the period such determination was made. At December 31, 2011, Homer City provided a full valuation allowance against its net deferred tax assets. For further information regarding the valuation allowance, see Note 6—Income Taxes.

41

On March 15, 2012, Homer City made an election to be treated as a partnership for federal and state income tax purposes. As a result, the income or loss of Homer City will be allocated to the individual partners. Accordingly, on a prospective basis, no recognition will be given to income taxes in Homer City's financial statements and deferred taxes and the related valuation allowance will be eliminated in the first quarter of 2012.

Interest income, interest expense and penalties associated with income taxes are reflected in provision for income taxes on Homer City's statements of operations.

New Accounting Guidance

Accounting Guidance Adopted in 2011

Fair Value Measurements and Disclosures

The Financial Accounting Standards Board (FASB) issued an accounting standards update modifying the disclosure requirements related to fair value measurements. Under these requirements, purchases and settlements for Level 3 fair value measurements are presented on a gross basis, rather than net. Homer City adopted this guidance effective January 1, 2011.

Accounting Guidance Not Yet Adopted

Fair Value Measurement

In May 2011, the FASB issued an accounting standards update modifying the fair value measurement and disclosure guidance. This guidance prohibits grouping of financial instruments for purposes of fair value measurement and requires the value be based on the individual security. This amendment also results in new disclosures primarily related to Level 3 measurements including quantitative disclosure about unobservable inputs and assumptions, a description of the valuation processes and a narrative description of the sensitivity of the fair value to changes in unobservable inputs. Homer City will adopt this guidance in the first quarter of 2012. The adoption of this standards update is not expected to have a material impact on Homer City's financial position.

Presentation of Comprehensive Income

In June 2011, the FASB issued an accounting standards update on the presentation of comprehensive income. An entity can elect to present items of net income and other comprehensive income in one continuous statement, referred to as the statement of comprehensive income, or in two separate but consecutive statements. Homer City will adopt this guidance in the first quarter of 2012. Homer City currently presents the statement of comprehensive income immediately following the statement of income and expects to continue to do so. The adoption of this accounting standards update does not change the items that constitute net income and other comprehensive income.

Offsetting Assets and Liabilities

In December 2011, the FASB issued an accounting standards update modifying disclosure requirements about the nature of an entity's rights of offsetting assets and liabilities in the statement of financial position under master netting agreements and related arrangements associated with financial and derivative instruments. The guidance requires increased disclosure of the gross and net recognized assets and liabilities, collateral positions and narrative descriptions of setoff rights. Homer City will adopt this guidance effective January 1, 2013. The guidance impacts disclosure only.

Note 2. Property, Plant and Equipment

Property, plant and equipment consisted of the following:

	December 31,
(in millions)	2011		2010
Land	$	7	$	7
Power plant facilities	2		4
Plant and equipment under lease financing	760		1,582
Leasehold improvements	110		172
Emission allowances	198		438
Construction in progress	7		25
Equipment, furniture and fixtures	1		10
Capitalized leased equipment	—		1
	1,085		2,239
Less accumulated depreciation and amortization	—		609
Property, plant and equipment, net	$	1,085	$	1,630

As a result of the sale-leaseback transaction on December 7, 2001, a majority of the generating facilities and equipment were classified as power plant and equipment under lease financing. Homer City recorded amortization expense related to the leased facilities of $47 million for all three years ended December 31, 2011, 2010 and 2009. Accumulated amortization related to the leased facilities was none and $427 million at December 31, 2011 and 2010, respectively.

Homer City recorded $478 million of impairment charges related to property, plant and equipment at the Homer City plant in 2011. For additional information, see Note 12—Asset Impairments and Other Charges.

Asset Retirement Obligations

Authoritative guidance on asset retirement obligations (AROs) requires entities to record the fair value of a liability for an ARO in the period in which it is incurred, including a liability for the fair value of a conditional ARO, if the fair value can be reasonably estimated even though uncertainty exists about the timing and/or method of settlement. When an ARO liability is initially recorded, the entity capitalizes the cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is increased for accretion expense to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. Settlement of an ARO liability for an amount other than its recorded amount results in an increase or decrease in expense.

Homer City recorded a liability representing expected future costs associated with site reclamation, facilities dismantlement and removal of environmental hazards, which is included in benefit plans and other long-term liabilities on Homer City's balance sheets. A reconciliation of the changes in the ARO liability is as follows:

	Years Ended December 31,
(in millions)	2011		2010		2009
Beginning balance	$	7	$	5	$	3
Accretion expense	1		1		—
Liabilities added	—		1		2
Ending balance	$	8	$	7	$	5

Note 3. Fair Value Measurements

Recurring Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (referred to as an "exit price"). Fair value of an asset or a liability should consider assumptions that market participants would use in pricing the asset or liability, including assumptions about

43

nonperformance risk. The fair value of derivative assets' nonperformance risk was not material as of December 31, 2011 and 2010.

Homer City categorizes financial assets and liabilities into a fair value hierarchy based on valuation inputs used to derive fair value. The hierarchy, established by authoritative accounting guidance, gives the highest priority to unadjusted quoted market prices in active markets for identical assets and liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

The following table sets forth Homer City's assets and liabilities that were accounted for at fair value by level within the fair value hierarchy:

	December 31, 2011
(in millions)	Level 1		Level 2		Level 3		Netting1		Total
Assets at Fair Value
Money market funds2	$	28	$	—	$	—	$	—	$	28
Electricity contracts	—		1		—		—		1

Electricity contracts	—		5		—		3		8
Liabilities at Fair Value
Electricity contracts	$	—	$	3	$	—	$	3	$	6

¹  Represents the impact of netting across the levels of the fair value hierarchy. Netting among positions classified within the same level is included in that level.

²  Money market funds are included in cash and cash equivalents on Homer City's balance sheets.

The following table sets forth a summary of changes in the fair value of derivative assets and liabilities, net categorized as Level 3:

(in millions)	2011			2010
Fair value, net asset at beginning of periods	$	—		$	—
Total realized/unrealized gains (losses):

Settlements	2			—
Transfers in or out of Level 3	—			—
Fair value, net asset at end of periods	$	—		$	—

¹  Reported in operating revenues on Homer City's statements of operations.

The change in unrealized gains (losses) related to assets and liabilities, net held at December 31, 2011 and 2010 for the years ended December 31, 2011 and 2010 was immaterial.

Homer City determines the fair value of transfers in and out of each level at the end of each reporting period. There were no significant transfers between levels during 2011, 2010 and 2009.

44

Valuation Techniques used to Determine Fair Value

Level 1

Level 1 includes financial assets and liabilities where unadjusted quoted prices in active markets are available at the measurement date for identical assets and liabilities. Financial assets and liabilities classified as Level 1 include exchange-traded derivatives and money market funds.

Level 2

Level 2 pricing inputs include quoted prices for similar assets and liabilities in active markets and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the derivative instrument. Financial assets and liabilities utilizing Level 2 inputs include over-the-counter derivatives.

Derivative contracts that are over-the-counter traded are valued using pricing models and are generally classified as Level 2. Inputs to the pricing models include forward published or posted clearing prices from exchanges (New York Mercantile Exchange and Intercontinental Exchange) for similar instruments and discount rates. Forward market prices are developed based on the source that best represents trade activity in each market. Broker quotes or prices from exchanges are used to validate and corroborate the primary source. These price quotations reflect mid-market prices (average of bid and ask) and are obtained from sources believed to provide the most liquid market for the commodity. Broker quotes are incorporated when corroborated with other information which may include a combination of prices from exchanges, other brokers, and comparison to executed trades.

Level 3

Level 3 includes financial assets and liabilities where fair value is determined using techniques that require significant unobservable inputs. Over-the-counter options, bilateral contracts, capacity contracts, qualifying facilities contracts, derivative contracts that trade infrequently (such as financial transmission rights), and derivative contracts with counterparties that have significant nonperformance risks are classified as Level 3. In circumstances where EMMT cannot verify fair value with observable market transactions, it is possible that a different valuation model could produce a materially different estimate of fair value. As markets continue to develop and more pricing information becomes available, EMMT continues to assess valuation methodologies used to determine fair value.

For derivative contracts that trade infrequently (illiquid financial transmission rights), changes in fair value are based on the hypothetical sale of illiquid positions. Objective criteria are reviewed, including system congestion and other underlying drivers and fair value is adjusted when it is concluded that a change in objective criteria would result in a new valuation that better reflects fair value. For illiquid long-term power agreements, fair value is based upon a discounting of future electricity and natural gas prices derived from a proprietary model using the risk free discount rate for a similar duration contract, adjusted for credit risk and market liquidity. Changes in fair value are based on changes to forward market prices, including forecasted prices for illiquid forward periods. The fair value of the majority of Homer City's derivatives that are classified as Level 3 is determined using uncorroborated non-binding broker quotes and models that may require EMMT to extrapolate short-term observable inputs in order to calculate fair value. Broker quotes are obtained from several brokers and compared against each other for reasonableness.

Non-Recurring Fair Value Measurements

For a discussion of non-recurring fair value measurements, see Note 12—Asset Impairments and Other Charges.

Note 4. Long-Term Debt

Homer City has entered into a subordinated revolving loan agreement with Edison Mission Finance Co. This loan agreement bears interest at a fixed rate of 8.0% on outstanding amounts and terminates on March 18, 2014. The outstanding balance under the loan agreement was $490 million and $479 million at December 31, 2011 and 2010, respectively. Homer City is restricted as a part of the sale-leaseback transaction from making any payments under this facility unless specified conditions are met. Homer City incurred interest costs related to its affiliate debt of $40 million, $38 million and $36 million for the years ended December 31, 2011, 2010 and 2009, respectively. It is not practicable to estimate the fair value of this financial instrument due to the subordination features of the loan and the provisions of the sale-leaseback agreements for the Homer City plant.

45

Note 5. Derivative Instruments and Hedging Activities

Homer City uses derivative instruments to reduce its exposure to market risks that arise from price fluctuations of electricity, capacity, fuel, emission allowances, and transmission rights. The derivative financial instruments vary in duration, ranging from a few days to several years, depending upon the instrument. To the extent that Homer City does not use derivative instruments to hedge these market risks, the unhedged portions will be subject to the risks and benefits of spot market price movements.

Risk management positions may be designated as cash flow hedges or economic hedges, which are derivatives that are not designated as cash flow hedges. Economic hedges are accounted for at fair value on Homer City's balance sheets as derivative assets or liabilities with offsetting changes recorded on the statements of operations. For derivative instruments that qualify for hedge accounting treatment, the fair value is recognized on Homer City's balance sheets as derivative assets or liabilities with offsetting changes in fair value, to the extent effective, recognized in accumulated other comprehensive loss until reclassified into earnings when the related forecasted transaction occurs. The portion of a cash flow hedge that does not offset the change in the fair value of the transaction being hedged, which is commonly referred to as the ineffective portion, is immediately recognized in earnings. The results of derivative activities are recorded in cash flows from operating activities on the statements of cash flows.

Where Homer City's derivative instruments are subject to a master netting agreement and the criteria of authoritative guidance are met, Homer City presents its derivative assets and liabilities on a net basis on its balance sheets.

Notional Volumes of Derivative Instruments

The following table summarizes the notional volumes of derivatives used for hedging activities:

December 31, 2011
Commodity	Instrument	Classification	Unit of Measure	Cash Flow Hedges		Economic Hedges
Electricity	Forwards/Futures	Sales, net	GWh	—		90	3
Electricity	Capacity	Sales, net	MW-Day (in thousands)	29	2	—
Electricity	Congestion	Purchases, net	GWh	—		1,267	4
December 31, 2010
Electricity	Forwards/Futures	Sales, net	GWh	2,767	1	—
Electricity	Forwards/Futures	Purchases, net	GWh	—		20	3
Electricity	Capacity	Sales, net	MW-Day (in thousands)	36	2	—
Electricity	Congestion	Purchases, net	GWh	—		367	4

¹  Homer City's hedge products include forward and futures contracts that qualify for hedge accounting. This category excludes power contracts for the Homer City plant which meet the normal purchases and sales exception and are accounted for on the accrual method.

²  Homer City's hedge transactions for capacity result from bilateral trades. Capacity sold in the PJM Reliability Pricing Model (RPM) auction is not accounted for as a derivative.

³  These positions adjust financial and physical positions, or day-ahead and real-time positions, to reduce costs or increase gross margin. The net sales positions of these categories are primarily related to hedge transactions that are not designated as cash flow hedges.

⁴  Congestion contracts include financial transmission rights, transmission congestion contracts or congestion revenue rights. These positions are similar to a swap, where the buyer is entitled to receive a stream of revenues (or charges) based on the hourly day-ahead price differences between two locations.

Commodity Price Risk Management

Homer City's operations are exposed to commodity price risk, which reflects the potential impact of a change in the market value of a particular commodity. Commodity price risks are actively monitored, with oversight provided by a risk management committee, to ensure compliance with Homer City's risk management policies, through EMMT. EMMT uses estimates of the variability in gross margin to help identify, measure, monitor and control Homer City's overall market risk exposure and earnings volatility with respect to hedge positions at the Homer City plant. This measure allows management to aggregate overall commodity risk, compare risk on a consistent basis and identify changes in risk factors. Variability in gross margin measures the potential change in value of an asset or position, in each case over a given time interval, under normal market conditions, at a given confidence level. Given the inherent limitations of this measure and reliance on a single type of risk measurement tool, EMMT supplements this approach with the use of stress testing and worst-case scenario analysis for key risk factors, as well as stop-loss triggers and volumetric exposure limits. When appropriate, EMMT manages the spread between the electric prices and fuel prices, and uses forward contracts, swaps, futures, or options contracts to achieve those objectives.

Credit Risk

In conducting Homer City's marketing activities, EMMT enters into transactions with utilities, energy companies, financial institutions, and other companies, collectively referred to as counterparties. In the event a counterparty were to default on its trade obligation, Homer City would be exposed to the risk of possible loss associated with market price changes occurring since the original contract was executed if the nonperforming counterparty were unable to pay the resulting damages owed to Homer City. Further, Homer City would be exposed to the risk of non-payment of accounts receivable accrued for products delivered prior to the time a counterparty defaulted.

Credit risk is measured as the loss that EMMT would expect to incur if a counterparty failed to perform pursuant to the terms of its contractual obligations. To manage credit risk, EMMT evaluates the risk of potential defaults by counterparties. To mitigate credit risk from counterparties, master netting agreements are used whenever possible and counterparties may be required to pledge collateral when deemed necessary.

The majority of the coal for the Homer City plant is purchased from suppliers under contracts which may be for multiple years. None of the coal suppliers to the Homer City plant have investment grade credit ratings and, accordingly, Homer City may have limited recourse to collect damages in the event of default by a supplier.

Homer City derives a significant source of its operating revenues from electric power sold into the PJM market by EMMT. Sales into PJM accounted for approximately 91%, 69% and 33% of Homer City's operating revenues for the years ended December 31, 2011, 2010 and 2009, respectively. Moody's Investors Service, Inc. (Moody's) rates PJM's debt Aa3. PJM, a regional transmission organization (RTO) with over 300 member companies, maintains its own credit risk policies and does not extend unsecured credit to non-investment grade companies. Losses resulting from a PJM member default are shared by all other members using a predetermined formula.

For the years ended December 31, 2011, 2010 and 2009, EMMT made sales to Constellation Energy Commodities Group, Inc. (Constellation) that accounted for less than 1%, 19% and 41%, respectively, of Homer City's operating revenues. Sales to Constellation consisted of energy sales under forward contracts. The contract with Constellation is guaranteed by Constellation Energy Group, Inc., which has a senior unsecured debt rating of BBB- by Standard & Poor's Ratings Services (S&P) and Baa3 by Moody's. At December 31, 2011 and 2010, EMMT's account receivable due from Constellation was none and $13 million, respectively.

During the fourth quarter of 2011, Homer City recorded a valuation allowance on its deferred tax assets due to it being more likely than not that Homer City will be unable to realize the benefits. The total valuation allowance was $344 million for the year ended December 31, 2011, of which $6 million was reflected in other comprehensive income (loss) and the remainder was reflected in net loss.

As of December 31, 2011, Homer City had $81 million of federal net operating loss carryforwards and $12 million of state net operating loss carryforwards, both of which expire in 2031, if unused.

On March 15, 2012, Homer City made an election to be treated as a partnership for federal and state income tax purposes. As a result, the income or loss of Homer City will be allocated to the individual partners. Accordingly, on a prospective basis, no recognition will be given to income taxes in Homer City's financial statements and deferred taxes and the related valuation allowance will be eliminated in the first quarter of 2012.

Accounting for Uncertainty in Income Taxes

Unrecognized Tax Benefits

At December 31, 2011 and 2010, Homer City had $3 million and $2 million, respectively, of unrecognized tax benefits. Homer City had no unrecognized tax benefits at December 31, 2009. As of December 31, 2011 and 2010, $1 million of unrecognized tax benefits, if recognized, would impact the effective tax rate.

Edison International's federal income tax returns and California combined franchise tax returns are currently open for years subsequent to 2002. In addition, specific California refund claims made by Edison International for years 1991 through 2002 remain subject to audit.

Accrued Interest and Penalties

The total amount of accrued interest expense and penalties was not material as of December 31, 2011 and 2010. The total amount of net after-tax interest expense and penalties recognized in income tax expense was not material for each of 2011, 2010 and 2009.

Bonus Depreciation Impact

The Small Business Jobs Act of 2010 and the Tax Relief, Unemployment Insurance Reauthorization and Job Creation Act of 2010 (2010 Tax Relief Act) extended 50% bonus depreciation for qualifying property through 2012 and created a new 100% bonus depreciation for qualifying property placed in service between September 9, 2010 and December 31, 2011. Subject to updated Internal Revenue Service regulations clarifying the definitions of capital expenditures that qualify for 100% bonus depreciation, Homer City's capital expenditures are expected to qualify, accelerating federal tax deductions in 2011.

Note 7. Compensation and Benefit Plans

Employees of Homer City are eligible for various benefit plans of Edison International.

Employee Savings Plan

A 401(k) plan is maintained to supplement eligible employees' retirement income. Homer City matches 100% of non-union employee contributions up to 6% of such employees' base annual compensation. Homer City also matches 70% of contributions made by union employees, up to 4% of base annual compensation. Employer contributions vest 20% per year. Contribution expense was approximately $1 million for each year ended December 31, 2011, 2010 and 2009.

50

Pension Plans and Postretirement Benefits Other Than Pensions

Pension Plans

Homer City maintains a pension plan specifically for the benefit of its union employees. A portion of Homer City's non-union employees participate in the Edison International pension plan. Eligibility depends on a number of factors, including the employee's hire date. Both plans are noncontributory, defined benefit pension plans and cover employees who fulfill minimum service requirements. The Edison International plan has a cash balance feature. The expected contributions (all by employer) for the plans are approximately $2.6 million for the year ended December 31, 2012.

The funded position of the company's pension is very sensitive to changes in market conditions. Changes in overall interest rate levels significantly affect the company's liabilities, while assets held in the various trusts established to fund the company's long-term pension are affected by movements in the equity and bond markets. The market value of the investments (reflecting investment returns, contributions and benefit payments) within the plan trusts declined 35% during 2008. This reduction in value of plan assets combined with increased liabilities has resulted in a change in the pension plan funding status from a surplus to a material deficit, which will result in increased future expense and cash contributions. The company pension remains underfunded as liabilities have increased significantly as a result of steady declines in interest rates.

Postretirement Benefits Other Than Pensions

Homer City's non-union employees retiring at or after age 55 with at least ten years of service may be eligible for postretirement medical, dental, and vision coverage. Eligibility for a company contribution toward the cost of these benefits in retirement depends on a number of factors, including the employee's hire date. The expected contributions (all by the employer) for the postretirement benefits other than pensions are $1.1 million for the year ended December 31, 2012.

Discount Rate

The discount rate enables Homer City to state expected future cash flows at a present value on the measurement date. Homer City selects its discount rate by performing a yield curve analysis. This analysis determines the equivalent discount rate on projected cash flows, matching the timing and amount of expected benefit payments. Two corporate yield curves were considered, Citigroup and AON-Hewitt.

Plan Assets

Description of Pension and Postretirement Benefits Other than Pensions Investment Strategies

The investment of plan assets is overseen by a fiduciary investment committee. Plan assets are invested using a combination of asset classes, and may have active and passive investment strategies within asset classes. Target allocations for pension plan assets are 30% for U.S. equities, 16% for non-U.S. equities, 35% for fixed income, 15% for opportunistic and/or alternative investments and 4% for other investments. Edison International employs multiple investment management firms. Investment managers within each asset class cover a range of investment styles and approaches. Risk is managed through diversification

55

among multiple asset classes, managers, styles and securities. Plan, asset class and individual manager performance is measured against targets. Edison International also monitors the stability of its investment managers' organizations.

Allowable investment types include:

• United States Equities: Common and preferred stocks of large, medium, and small companies which are predominantly United States-based.

• Non-United States Equities: Equity securities issued by companies domiciled outside the United States and in depository receipts which represent ownership of securities of non-United States companies.

• Fixed Income: Fixed income securities issued or guaranteed by the United States government, non-United States governments, government agencies and instrumentalities including municipal bonds, mortgage backed securities and corporate debt obligations. A portion of the fixed income positions may be held in debt securities that are below investment grade.

Opportunistic, Alternative and Other Investments:

• Opportunistic: Investments in short to intermediate term market opportunities. Investments may have fixed income and/or equity characteristics and may be either liquid or illiquid.

• Alternative: Limited partnerships that invest in non-publicly traded entities.

• Other: Investments diversified among multiple asset classes such as global equity, fixed income currency and commodities markets. Investments are made in liquid instruments within and across markets. The investment returns are expected to approximate the plans' expected investment returns.

Asset class portfolio weights are permitted to range within plus or minus 3%. Where approved by the fiduciary investment committee, futures contracts are used for portfolio rebalancing and to reallocate portfolio cash positions. Where authorized, a few of the plans' investment managers employ limited use of derivatives, including futures contracts, options, options on futures and interest rate swaps in place of direct investment in securities to gain efficient exposure to markets. Derivatives are not used to leverage the plans or any portfolios.

Determination of the Expected Long-Term Rate of Return on Assets

The overall expected long-term rate of return on assets assumption is based on the long-term target asset allocation for plan assets and capital markets return forecasts for asset classes employed.

Capital Markets Return Forecasts

Our capital markets return forecast methodologies primarily use a combination of historical market data, current market conditions, proprietary forecasting expertise, complex models to develop asset class return forecasts and a building block approach. The forecasts are developed using variables such as real risk-free interest, inflation, and asset class specific risk premiums. For equities, the risk premium is based on an assumed average equity risk premium of 6% over cash. The forecasted return on private equity and opportunistic investments are estimated at a 3% premium above public equity, reflecting a premium for higher volatility and liquidity. For fixed income, the risk premium is based off of a comprehensive modeling of credit spreads.

Fair Value of Plan Assets

The plan assets for Homer City pension are included in the Southern California Edison Company Retirement Plan Trust (Master Trust) assets which include investments in equity securities, U.S. treasury securities, other fixed-income securities, common/collective funds, mutual funds, other investment entities, foreign exchange and interest rate contracts, and partnership/joint ventures. Equity securities, U.S. treasury securities, mutual and money market funds are classified as Level 1 as fair value is determined by observable, unadjusted quoted market prices in active or highly liquid and transparent markets. Common/collective funds are valued at the net asset value (NAV) of shares held. Although common/collective funds are determined by observable prices, they are classified as Level 2 because they trade in markets that are less active and transparent. The fair value of the underlying investments in equity mutual funds and equity common/collective funds are based upon stock-exchange prices. The fair value of the underlying investments in fixed-income common/collective funds, fixed-income mutual funds and other fixed income securities including municipal bonds are based on evaluated prices that reflect significant observable market information such as reported trades, actual trade information of similar securities, benchmark yields, broker/dealer quotes, issuer spreads, bids, offers and relevant credit information. Foreign exchange and interest rate contracts are classified as Level 2 because the values are based on observable prices but are not traded on an exchange. Futures contracts trade on an exchange and therefore are classified as Level 1. One of the partnerships is classified as Level 2 since this investment can be

56

readily redeemed at NAV and the underlying investments are liquid publicly traded fixed-income securities which have observable prices. The remaining partnerships/joint ventures are classified as Level 3 because fair value is determined primarily based upon management estimates of future cash flows. Other investment entities are valued similarly to common collective funds and are therefore classified as Level 2. The Level 1 registered investment companies are either mutual or money market funds. The remaining funds in this category are readily redeemable at NAV and classified as Level 2 and are discussed further at footnote 7 to the pension plan master trust investments table below.

Edison International reviews the process/procedures of both the pricing services and the trustee to gain an understanding of the inputs/assumptions and valuation techniques used to price each asset type/class. For further discussion see Note 3—Fair Value Measurements.

¹  Corporate stocks are diversified. For 2011 and 2010, respectively, performance is primarily benchmarked against the Russell Indexes (60% and 63%) and Morgan Stanley Capital International (MSCI) index (40% and 37%).

²  Partnerships/joint venture Level 2 investments consist primarily of a partnership which invests in publicly traded fixed income securities, primarily from the banking and finance industry and U.S. government agencies. At December 31, 2011 and 2010,

57

respectively, approximately 55% and 60% of the Level 3 partnerships are invested in (1) asset backed securities, including distressed mortgages and (2) commercial and residential loans and debt and equity of banks. The remaining Level 3 partnerships are invested in small private equity and venture capital funds. Investment strategies for these funds include branded consumer products, early stage technology, California geographic focus, and diversified US and non-US fund-of-funds.

³  At December 31, 2011 and 2010, respectively, the common/collective assets were invested in equity index funds that seek to track performance of the Standard and Poor's (S&P 500) Index (29% and 29%), Russell 200 and Russell 1000 indexes (27% and 28%) and the MSCI Europe, Australasia and Far East (EAFE) Index (10% and 11%). A non-index U.S. equity fund representing 23% of this category for both 2011 and 2010 is actively managed. Another fund representing 8% of this category for both 2011 and 2010 is a global asset allocation fund.

⁴  Corporate bonds are diversified. At December 31, 2011 and 2010, respectively, this category includes $53 million and $65 million for collateralized mortgage obligations and other asset backed securities of which $10 million and $17 million are below investment grade.

⁵  Level 1 U.S. government and agency securities are U.S. treasury bonds and notes. Level 2 primarily relates to the Federal National Mortgage Association and the Federal Home Loan Mortgage Corporation.

⁶  Other investment entities were primarily invested in (1) emerging market equity securities, (2) a hedge fund that invests through liquid instruments in a global diversified portfolio of equity, fixed income, interest rate, foreign currency and commodities markets, and (3) domestic mortgage backed securities.

⁷  Level 1 of registered investment companies consisted of a global equity mutual fund which seeks to outperform the MSCI World Total Return Index. Level 2 primarily consisted of short-term, emerging market, high yield bond funds and government inflation-indexed bonds.

At both December 31, 2011 and 2010, approximately 69% of the publicly traded equity investments, including equities in the common/collective funds, were located in the United States.

The following table sets forth a summary of changes in the fair value of Level 3 investments for 2011 and 2010:

Note 8. Commitments and Contingencies

Lease Commitments

Homer City has a lease financing with respect to its facilities, which is described in more detail below. Homer City also has operating leases in place relating mainly to tractors and trucks.

58

At December 31, 2011, the future operating and lease financing commitments were as follows:

Years Ending December 31, (in millions)	Operating Leases		Lease Financing

2016	—		89
Thereafter	—		1,171
Total future commitments	$	2	$	1,814
Amount representing interest			808
Net commitments			$	1,006

Operating lease expense amounted to $1 million for each year ended December 31, 2011, 2010 and 2009.

Facilities Sale-Leaseback

On December 7, 2001, Homer City completed the sale-leaseback of its Homer City plant to third-party lessors. The transaction has been accounted for as a lease financing for accounting purposes, which means that Homer City reflects the Homer City plant as an asset on its balance sheet, although Homer City has no legal ownership, and records the net present value of the future minimum lease payments as lease debt. Under the terms of the 33.67 year leases, Homer City is obligated to make semi-annual lease payments on each April 1 and October 1. The gain on the sale of the Homer City plant has been deferred and is being amortized over the term of the lease.

Under the participation agreements entered into as part of the sale-leaseback transaction, Homer City's ability to enter into specified transactions and to engage in specified business activities, including financing and investment activities, is subject to significant restrictions. These restrictions could affect, and in some cases significantly limit or prohibit, its ability to, among other things, merge, consolidate or sell its assets, create liens on its properties or assets, enter into non-permitted trading activities, enter into transactions with its affiliates, incur indebtedness, create, incur, assume or suffer to exist guarantees or contingent obligations, make restricted payments to its partners, make capital expenditures, own subsidiaries, liquidate or dissolve, engage in non-permitted business activities, sublease its leasehold interests in the facilities or make improvements to the facilities. Accordingly, Homer City's liquidity is substantially based on its ability to generate cash flow from operations. For additional discussion regarding potential impact to the lease agreements, see Note 1—Summary of Significant Accounting Policies—Substantial Doubt that Homer City will Continue as a Going Concern.

Under the sale-leaseback documents, Homer City rent payments are comprised of two components, senior rent and equity rent.Senior rent is used exclusively for debt service to secured lease obligation bondholders, while equity rent is paid to the owner-lessors.In order to pay equity rent, among other requirements, Homer City must meet historical and projected senior rent service coverage ratios of 1.7 to 1 (subject to reduction to 1.3 to 1 under certain circumstances).The senior rent service coverage ratio of 1.18 to 1 for the 12 months ended December 31, 2011 was below the covenant threshold and Homer City also did not meet the threshold for the prospective two 12-month periods, which currently precludes Homer City from making distributions, including repayment of certain intercompany loans and from paying the equity portion of the rent payment.A failure to pay equity rent does not entitle the owner-lessors to foreclose upon Homer City's leasehold interest, but it does result in the suspension of Homer City's ability to make permitted distributions.Moreover, Homer City would be permanently restricted in its ability to make permitted distributions if a failure to pay equity rent when due was not cured within nine months, or even if cured, occurred more than one additional time during the term of the lease.Homer City is not subject to any minimum historical and projected senior rent service coverage ratios except as conditions to distributions and equity rent payments.Also, failure by Homer City to pay equity rent when due in April 2012 could trigger termination of the $48 million senior rent reserve letter of credit.Homer City would then be required to fund the senior rent reserve, and failure to do so could entitle counterparties to seek available remedies under the sale-leaseback documents, including termination or foreclosure upon the leasehold interest.

Homer City's use of cash in its bank accounts is limited to specific operating and capital expenditures as set forth in the security deposit agreement executed as part of the sale-leaseback transaction. The amount in certain reserve accounts will be available for payments due on the equity portion of lease rent during specified periods, and in accordance with the sale-leaseback

59

documents, unless there is a default in the payment of the senior portion of lease rent, in which case the amount will be available to pay such senior portion of the lease rent. The release of funds from these restricted cash accounts is permitted, provided Homer City maintains specified reserve balances in accordance with the sale-leaseback documents, no event of default shall have occurred or be continuing and no two failed rent payments shall have occurred. Homer City had $20 million included in restricted deposits at each of December 31, 2011 and 2010 related to these reserve accounts.

Other Commitments

Certain other minimum commitments are estimated as follows:

(in millions)	2012		2013		2014
Fuel supply contracts	$	214	$	53	$	—
Capital expenditures	7		—		—
Coal cleaning agreement	6		—		—
Other contractual obligations	3		4		4
	$	230	$	57	$	4

Fuel Supply Contracts

At December 31, 2011, Homer City had commitments to purchase coal from third-party suppliers at fixed prices, subject to adjustment clauses. The contracts require Homer City to purchase a minimum quantity over the term of the contracts, with an option at Homer City's discretion to purchase additional amounts as stated in the agreements.

Capital Commitments

At December 31, 2011, Homer City plans to finance firm commitments for capital expenditures with cash generated from operations.

Coal Cleaning Agreement

Homer City entered into a coal cleaning agreement with Homer City Coal Processing Corporation to operate and maintain a coal cleaning plant owned by Homer City. The agreement expires on December 31, 2012.

Other Contractual Obligations

At December 31, 2011, Homer City had contractual commitments for the purchase of limestone.

Interconnection Agreement

Homer City is a party to an interconnection agreement with New York State Electric & Gas Corporation (NYSEG) and Pennsylvania Electric Company (Penelec) to provide interconnection services necessary to interconnect the Homer City plant with NYSEG's and Penelec's transmission systems. Unless terminated earlier in accordance with specified terms, the interconnection agreement will terminate on a date mutually agreed to by Homer City, NYSEG and Penelec. The termination date will not exceed the retirement date of the Homer City units. NYSEG and Penelec have agreed to extend the interconnection services (but not the expiration of the agreement) to modifications, additions or upgrades to, or repowering of the Homer City units. Homer City is required to compensate NYSEG and Penelec for all reasonable costs associated with any modifications, additions or replacements made to NYSEG's or Penelec's interconnection facilities or transmission systems in connection with any modification, addition or upgrade to, or repowering of the Homer City units.

Guarantees and Indemnities

Environmental Indemnity Related to the Homer City Plant

In connection with the acquisition of the Homer City plant, Homer City agreed to indemnify the sellers with respect to specified environmental liabilities before and after the date of sale. Edison Mission Energy (EME) guaranteed this obligation of Homer City. Also, in connection with the sale-leaseback transaction related to the Homer City plant, Homer City agreed to indemnify the owner-lessors for specified environmental liabilities. Due to the nature of the obligations under these indemnity provisions, they are not subject to a maximum potential liability and do not have expiration dates. Homer City has not recorded a liability related to this indemnity. For a discussion of the New Source Review lawsuit filed against Homer City, see "—Contingencies—New Source Review and Other Litigation."

60

Indemnities Provided under Sale-Leaseback Agreement

In connection with the sale-leaseback transaction related to the Homer City plant, Homer City and its indirect parent, EME, entered into tax indemnity agreements. Under certain of these tax indemnity agreements, Homer City, as the lessee in the sale-leaseback transaction agreed to indemnify the respective owner-lessors for specified adverse tax consequences that could result from certain situations set forth in each tax indemnity agreement, including specified defaults under the respective leases The potential indemnity obligations under these tax indemnity agreements could be significant. Due to the nature of these potential obligations, Homer City cannot determine a range of estimated obligation which would be triggered by a valid claim from the owner-lessors. Homer City has not recorded a liability related for these matters.

EME agreed to indemnify the owner-lessors in the sale-leaseback transaction related to the Homer City plant for certain negative federal income tax consequences should the rent payments be "levelized" for tax purposes and for potential foreign tax credit losses in the event that the owner-lessor's debt is characterized as recourse, rather than nonrecourse. This indemnity covers a limited range of possible tax consequences that are unrelated to performance under the lease.

Other Indemnities

Homer City provides other indemnifications through contracts entered into in the normal course of business. Homer City's obligations under these agreements may or may not be limited in terms of time and/or amount, and in some instances Homer City may have recourse against third parties. Homer City cannot determine a range of estimates and has not recorded a liability related to these indemnities.

Contingencies

In addition to the matters disclosed in these notes, Homer City is involved in other legal, tax and regulatory proceedings before various courts and governmental agencies regarding matters arising in the ordinary course of business. Homer City believes the outcome of these other proceedings, individually and in the aggregate, will not materially affect its results of operations or liquidity.

New Source Review and Other Litigation

In January 2011, the US EPA filed a complaint in the Western District of Pennsylvania against Homer City, the sale-leaseback owner participants of the Homer City plant, and two prior owners of the Homer City plant. The complaint alleged violations of the PSD and Title V provisions of the CAA, as a result of projects in the 1990s performed by prior owners without PSD permits and the subsequent failure to incorporate emissions limitations that meet BACT into the station's Title V operating permit. In addition to seeking penalties ranging from $32,500 to $37,500 per violation, per day, the complaint called for an injunction ordering Homer City to install controls sufficient to meet BACT emission rates at all units subject to the complaint and for other remedies. The PADEP (Pennsylvania Department of Environmental Protection), the State of New York and the State of New Jersey intervened in the lawsuit. In October 2011, all of the claims in the US EPA's lawsuit were dismissed with prejudice. An appeal of the dismissal is pending before the Third Circuit Court of Appeals.

Also in January 2011, two residents filed a complaint in the Western District of Pennsylvania, on behalf of themselves and all others similarly situated, against Homer City, the sale-leaseback owner participants of the Homer City plant, two prior owners of the Homer City plant, EME, and Edison International, claiming that emissions from the Homer City plant had adversely affected their health and property values. The plaintiffs sought to have their suit certified as a class action and requested injunctive relief, the funding of a health assessment study and medical monitoring, as well as compensatory and punitive damages. In October 2011, the claims in the purported class action lawsuit that were based on the federal CAA were dismissed with prejudice, while state law statutory and common law claims were dismissed without prejudice to re-file in state court should the plaintiffs choose to do so. Homer City does not know whether the plaintiffs will file a complaint in state court.

In February 2012, Homer City received a 60-day Notice of Intent to Sue indicating the Sierra Club’s intent to file a citizen lawsuit alleging violations of emissions standards and limitations under the CAA and the Pennsylvania Air Pollution Control Act.

Adverse decisions in these cases could involve penalties, remedial actions and damages that could have a material impact on the financial condition and results of operations of Homer City. Homer City cannot predict the outcome of these matters or estimate the impact on the Homer City plant, or its results of operations, financial position or cash flows. Homer City has not recorded a liability for this matter.

Ash Disposal Site

Homer City's ash disposal site is a permitted Class I Residual Waste Landfill, the most stringently regulated of the three categories of residual waste landfills authorized by the regulations of the PADEP. Homer City's permit allows it to dispose of

61

coal combustion by-products, including fly ash, bottom ash, pyrites, gypsum, and miscellaneous plant wastes at the landfill. The wastes are deposited in compacted layers within lifts, or sections. Each lift where coal ash is disposed must be capped and covered when it reaches final grade. Homer City must also monitor groundwater quality at and adjacent to the ash disposal site through a network of monitoring wells and report the results to the PADEP on a periodic basis. In the event that a disposal facility's groundwater monitoring identifies degradation in any of its wells, the PADEP's regulations require the facility to first confirm the existence and nature of the degradation by conducting a groundwater assessment. If the assessment confirms groundwater degradation in excess of the applicable regulatory standards, the facility is then required to prepare and implement an abatement plan that could include measures such as installing a liner in a previously unlined area. To date, no degradation has been found in the groundwater monitoring system at Homer City that would require the development of an assessment or abatement plan. Homer City also provides financial assurance in the form of a surety bond to guarantee its closure and post-closure obligations at the landfill. The estimated closure date is 2018. Based on the remaining capacity of the landfill and the estimated material requiring future disposal, Homer City has begun permitting additional areas for expansion of the landfill. Management does not believe that the costs of maintaining and closing the ash disposal site will have a material impact on Homer City's financial statements under current regulations.

Insurance

Homer City maintains insurance policies that it believes are comparable to those carried by other electric generating facilities of a similar size. The insurance program includes all-risk real and personal property insurance, including coverage for losses from boiler and machinery breakdowns, and the perils of earthquake and flood, subject to certain sublimits. The property insurance program currently covers losses up to $1.6 billion. Under the terms of the participation agreements entered into as part of Homer City's sale-leaseback transaction, Homer City is required to maintain specified minimum insurance coverages with insurers having specific minimum ratings if and to the extent that such insurance is available on a commercially reasonable basis. Some of the insurers providing Homer City's insurance do not meet the minimum ratings required under the participation agreements. Homer City has obtained a waiver under the participation agreements which permits it to maintain its current insurance through June 1, 2012. Homer City also carries general liability insurance covering liabilities to third parties for bodily injury or property damage resulting from operations, automobile liability insurance and excess liability insurance. Limits and deductibles in respect of these insurance policies are consistent with the requirements of the participation agreements. However, some insurers providing general liability coverage do not meet the minimum ratings requirements under the participation agreements. The waiver obtained permits Homer City to retain these insurers for all of its insurance coverages.

Note 9. Environmental Developments

Environmental Issues and Capital Resource Limitations

Homer City has begun work on designing SO₂ and particulate emissions control equipment for Units 1 and 2 and preparing the site for their installation. The estimated cost of installing SO₂and particulate emissions control equipment for Units 1 and 2of the Homer City plant is expected to be approximately $700 million to $750 million.In order for this emissions control equipment to be operational by early 2014, which is the expected deadline under the currently applicable Federal environmental regulations, the construction process would need to begin in the second quarter of 2012.A contractor for engineering, procurement and construction services has been selected to install and construct the emissions control equipment for the Homer City plant. However, construction of these improvements is dependent upon funding from the owner-lessors or third parties. For additional information, see Note 1—Summary of Significant Accounting Policies—Substantial Doubt that Homer City will Continue as a Going Concern.

Greenhouse Gas Regulation

There have been a number of federal and state legislative and regulatory initiatives to reduce greenhouse gas (GHG) emissions. Any climate change regulation or other legal obligation that would require substantial reductions in GHG emissions or that would impose additional costs or charges for the GHG emissions could significantly increase the cost of generating electricity from fossil fuels, and especially from coal-fired plants, which could adversely affect Homer City's business.

Significant developments include the following:

• In June 2010, the US EPA issued the Prevention of Significant Deterioration (PSD) and Title V Greenhouse Gas Tailoring Rule, known as the "GHG tailoring rule." This regulation generally subjects newly constructed sources of GHG emissions and newly modified existing major sources to the PSD air permitting program (and later, to the Title V permitting program), beginning in January 2011. The current program, which applies to only new or newly modified sources, is not expected to have an immediate effect on the Homer City plant. However, regulation of GHG emissions pursuant to this program could affect efforts to modify the Homer City plant in the future, and could subject new capital projects to additional permitting and emissions control requirements that could delay such projects. A challenge to the GHG tailoring

62

rule (along with other GHG regulations and determinations issued by the US EPA) is pending before the U.S. Court of Appeals for the D.C. Circuit.

• Under a December 2010 settlement agreement, the US EPA was to propose performance standards for GHG emissions from new and modified power plants and emissions guidelines for existing power plants. Proposed GHG emissions limits for new power plants were released by the US EPA on March 27, 2012. The status of the US EPA's efforts to develop GHG emissions performance standards for existing plants that are modified, and emissions guidelines for unmodified existing power plants (which would trigger a requirement for states to revise their SIPs) is unknown.

• In June 2011, the U.S. Supreme Court dismissed public nuisance claims against five power companies, ruling that the CAA and the US EPA actions the CAA authorizes displace federal common law nuisance claims that might arise from the emission of greenhouse gases.The court also affirmed the Second Circuit's determination that at least some of the plaintiffs had standing to bring the case.The court did not address whether the CAA also preempts state law claims arising from the same circumstances.

• An appeal before the Ninth Circuit of a federal district order dismissing a case against EME's parent company, Edison International, and other defendants, had been deferred pending the U.S. Supreme Court's ruling described above. In the case, which was brought by the Alaskan Native Village of Kivalina, the plaintiffs seek damages of up to $400 million for the cost of relocating the village, which they claim is no longer protected from storms because the Arctic sea ice has melted as the result of climate change. The stay of the appeal has been lifted and argument before the Ninth Circuit was held in November 2011.

• In May 2011, private citizens filed a purported class action complaint in the United States District Court for the Southern District of Mississippi, naming a large number of defendants, including Homer City's parent company EME. Plaintiffs allege that the defendants' activities resulted in emissions of substantial quantities of greenhouse gases that have contributed to climate change and sea level rise, which in turn are alleged to have increased the destructive force of Hurricane Katrina. The lawsuit alleged causes of action for negligence, public and private nuisance, and trespass, and seeks unspecified compensatory and punitive damages. The claims in this lawsuit were nearly identical to a subset of the claims that were raised against many of the same defendants in a previous lawsuit that was filed in, and dismissed by, the same federal district court where the current case has been filed. In March 2012, the United States District Court dismissed all of the plaintiffs' claims. Homer City does not know whether the plaintiffs will appeal this ruling.

Cross-State Air Pollution Rule

On July 6, 2011, the US EPA adopted the Cross-State Air Pollution Rule (CSAPR).CSAPR establishes emissions reductions for annual sulfur dioxide (SO₂) emissions and annual and ozone season nitrogen oxide (NO_x) emissions in two phases: a first phase originally scheduled to be effective January 1, 2012 and, in most states subject to the program(including Pennsylvania), a second phase effective January 1, 2014 that requires additional reductions in annual SO₂emissions.

In December 2011, the United States Court of Appeals for the District of Columbia granted a stay of CSAPR pending completion of its review of the rule's validity.Oral argument is scheduled for April 13, 2012, and a court decision is expected during the third quarter of 2012.The court directed the US EPA to continue administering the CAIR until its review is completed.

Hazardous Air Pollutant Regulations

In December 2011, the US EPA announced the Mercury and Air Toxics Standards (MATS) rule, limiting emissions of hazardous air pollutants (HAPs) from coal- and oil-fired electrical generating units. The rule was published in the Federal Register on February 16, 2012, and becomes effective on April 16, 2012.Homer Citydoes not expect that these standards will require Homer City to make additional capital expenditures beyond those that would be required for compliance with CSAPR Phase II.

Coal Combustion Wastes

US EPA regulations currently classify coal ash and other coal combustion residuals as solid wastes that are exempt from hazardous waste requirements.In June 2010, the US EPA published proposed regulations relating to coal combustion residuals that could result in their reclassification.Two different proposed approaches are under consideration.

The first approach, under which the US EPA would list these residuals as special wastes subject to regulation as hazardous wastes,could require Homer Cityto incur additional capital and operating costs The second approach, under which the US EPA would regulate these residuals as nonhazardous wastes, would establish minimum technical standards for units that are used for the disposal of coal combustion residuals, but would allow procedural and enforcement mechanisms (such as permit requirements) to be exclusively a matter of state law. Many of the proposed technical standards are similar under both proposed

63

options (for example, surface impoundments may need to be retrofitted, depending on which standard is finally adopted), but the second approach is not expected to require the retrofitting of landfills used for the disposal of coal combustion residuals.

Note 10. Accumulated Other Comprehensive Income (Loss)

Accumulated other comprehensive income (loss) consisted of the following:

(in millions)	Unrealized Gains (Losses) on Cash Flow Hedges			Unrecognized Losses and Prior Service Adjustments, Net1			Accumulated Other Comprehensive Income (Loss)
Balance at December 31, 2009	$	38		$	(2	)	$	36

Balance at December 31, 2010	3			(5		)	(2		)
Change for 2011	(6		)	(8		)	(14		)
Balance at December 31, 2011	$	(3	)	$	(13	)	$	(16	)

¹  For further detail, see Note 7—Compensation and Benefit Plans.

Unrealized losses on cash flow hedges, net of tax, at December 31, 2011, consist of futures and forward electricity contracts that qualify for hedge accounting. These losses arise because current forecasts of future electricity prices are higher than Homer City's contract prices. Approximately $1 million of unrealized gains on cash flow hedges are expected to be reclassified into earnings during the next 12 months. Management expects that reclassification of net unrealized gains will increase energy revenues recognized at market prices. Actual amounts ultimately reclassified into earnings over the next 12 months could vary materially from this estimated amount as a result of changes in market conditions. The maximum period over which a commodity cash flow hedge is designated is through May 31, 2014.

Note 12. Asset Impairments and Other Charges

Homer City recorded a $478 million charge related to asset impairments at the Homer City plant for the fourth quarter of 2011. Homer City failed to obtain sufficient interest from market participants to fund the capital improvements during the process undertaken in the fourth quarter of 2011, and Homer City is currently engaged in discussions with the owner-lessors regarding the potential for such funding.Homer City expects that the outcome of any such discussions, if successful in providing funding for the Homer City plant, will likely result in Homer City's loss of substantially all beneficial economic interest in and material control of the Homer City plant.Failure to resolve the source of funding of necessary capital expenditures for the Homer City plant could result in Homer City's default under the lease agreements giving rise to remedies for the owner-lessors and secured lease obligation bondholders, which could include foreclosing on the leased assets, the general partner of Homer City, or both. In connection with the preparation of its year-end financial statements, Homer City concluded that these events, combined with the current and projected financial condition of Homer City, were indicators of impairment. The long-lived asset group subject to the impairment evaluation was determined to include Homer City's property, plant and equipment.Homer City concluded that the future undiscounted cash flows were insufficient to recover the carrying amount of the asset group.To measure the

64

amount of impairment loss, the income approach was considered the most relevant and resulted in a fair value of $1,085 million.Discounted cash flow analysis based on estimates of future energy, capacity and coal prices and operations and maintenance costs along with the estimated costs of constructing the environmental control equipment was the technique utilized to determine fair value.

Homer City also recorded charges of $15 million, $5 million and $3 million in 2011, 2010 and 2009, respectively, primarily related to the retirement of equipment replaced during overhauls.

Fair Value

The fair value of the long-lived asset group as determined using the discounted cash flow models discussed above qualified as Level 3 in the fair value hierarchy.

Note 13. Related Party Transactions

EMMT Agreements

Homer City has entered into a master purchase, sale and services agreement with EMMT, pursuant to which EMMT arranges for purchases and sales of the following products, including related services: (i) electric energy and capacity; (ii) fuel oil; and (iii) emission allowances. Homer City compensates EMMT with respect to these transactions and reimburses EMMT for brokers fees, taxes, and other reasonably incurred direct out-of-pocket expenses. Payment for these services is due within 30 days of billing. The net fees earned by EMMT were less than $1 million for each of the years ended December 31, 2011, 2010 and 2009. EMMT prepays Homer City in advance for the full month's expected power generation. As a result of the accelerated payments, Homer City had liabilities to EMMT of $38 million and $45 million at December 31, 2011 and 2010, respectively, for products paid for by EMMT but not yet delivered by Homer City.

Homer City entered into several transactions through EMMT for the purchase or sale of SO₂ and NO_x allowances. All transactions were completed at the market price on the date of the transaction. Homer City received (paid) $0.4 million, $(5) million and $1 million during 2011, 2010 and 2009, respectively, for net sales (purchases) of SO₂ and NO_x allowances.

Affiliate Financing

Homer City obtained financing from Edison Mission Finance in connection with its acquisition of the Homer City plant. For further discussion, see Note 4—Long-Term Debt.

Services Agreements with EME and Edison International

Certain administrative services such as payroll, employee benefit programs, insurance, and information technology are shared among all affiliates of Edison International and the costs of these corporate support services are allocated to all affiliates. The cost of services provided by Edison International and EME, including those related to Homer City, are allocated based on one of the following formulas: percentage of the time worked, equity in investment and advances, number of employees, or multi-factor (operating revenues, operating expenses, total assets and total employees). Homer City participates in a common payroll and benefit program with all Edison International employees. In addition, Homer City is billed for any direct labor and out-of-pocket expenses for services directly requested for the benefit of the partnership. Homer City believes the allocation methodologies are reasonable. Homer City made reimbursements for the cost of these programs and other services totaling $6 million, $8 million and $9 million for the years ended December 31, 2011, 2010 and 2009, respectively. Homer City had a net payable of $0.3 million and $1 million at December 31, 2011 and 2010, respectively, related to these agreements.

Homer City participates in the insurance program of Edison International, including property, general liability, workers compensation and various other specialty policies. Homer City's insurance premiums are generally based on its share of risk related to each policy. In connection with the property insurance program, a portion of the risk is reinsured by a captive insurance subsidiary of Edison International.

Management and Administration Agreement with Midwest Generation EME, LLC

Homer City and Midwest Generation EME entered into a management and administration agreement pursuant to which Midwest Generation EME charges Homer City for management and administrative services. Actual costs billable under this agreement for each of the years ended December 31, 2011, 2010 and 2009 were $2 million. Homer City had a payable of $0.3 million and $0.2 million at December 31, 2011 and 2010, respectively, due to Midwest Generation EME related to this agreement.
