Item 1 — Business

General

  PART I

NRG Energy, Inc., or NRG or the Company, is an energy company built on dynamic retail brands with diverse generation 
assets. NRG brings the power of energy to consumers by producing, selling and delivering electricity and related products and 
services in major competitive power markets in the U.S. in a manner that delivers value to all of NRG's stakeholders. NRG is 
perfecting the integrated model by balancing retail load with generation supply within its deregulated markets, while evolving 
to a customer-driven business. The Company sells energy, services, and innovative, sustainable products and services directly 
to retail customers under the names "NRG" and "Reliant" and other brand names owned by NRG supported by approximately 
23,000(a) MW of generation as of December 31, 2018. NRG was incorporated as a Delaware corporation on May 29, 1992.

Strategy

NRG's strategy is to maximize stockholder value through the safe production and sale of reliable power to its customers 
in the markets served by the Company, while positioning the Company to provide innovative solutions to the end-use energy 
consumer. This strategy is designed to enable the Company to optimize the integrated model to generate predictable cash flow, 
significantly strengthen earnings and cost competitiveness, and lower risk and volatility. Sustainability is an integral piece of 
NRG's strategy and ties directly to business success, reduced risks and brand value. 

To effectuate the Company’s strategy, NRG is focused on: (i) serving the energy needs of end-use residential, commercial 
and industrial customers in competitive markets through multiple brands and channels with a variety of retail energy products 
and services differentiated by innovative features, premium service, sustainability, and loyalty/affinity programs; (ii) deploying 
innovative and renewable energy solutions for consumers within its retail businesses; (iii) excellence in operating performance 
of its existing assets including optimal hedging of generation assets and retail load operations; and (iv) engaging in a proactive 
capital allocation plan within the dictates of prudent balance sheet management.

Transformation Plan

NRG is well underway in executing its Transformation Plan. The Company expects to fully implement the Transformation 
Plan by the end of 2020 with a significant portion completed in 2018. The three-part, three-year plan is comprised of the following 
targets and the Company's achievements towards such targets are as follows:

Operations and Cost Excellence

Recurring cost savings and margin enhancement of $1,065 million, which consists of $590 million of cumulative cost 
savings, a $215 million net margin enhancement program, $50 million annual reduction in maintenance capital expenditures, 
and $210 million in permanent selling, general and administrative expense reduction associated with asset sales. The Company 
realized annual cost savings of $532 million and $32 million of margin enhancements during the year ended December 31, 2018 
and is on track to realize $590 million of cost savings and $135 million of margin enhancements in 2019.

The Company expects to realize (i) $370 million of non-recurring working capital improvements through 2020 and (ii) 
approximately  $290  million  of  one-time  costs  to  achieve.  By  December  31,  2018,  NRG  has  realized  $333  million  of  non-
recurring working capital improvements and $194 million of one-time costs to achieve, and expects to incur approximately $95 
million of one-time costs to achieve in 2019.

Portfolio Optimization

Targeted and completed $3.0 billion of asset sale cash proceeds received through February 28, 2019.

Capital Structure and Allocation

As of December 31, 2018, the Company achieved the previously announced target of reducing consolidated corporate debt 
to 3.0x net debt / adjusted EBITDA(b) credit ratio on a pro forma basis that includes the South Central Portfolio sale proceeds. 
As of February 28, 2019, the Company completed $1.5 billion of share repurchases.

Business Overview

As of December 31, 2018, the Company’s core businesses include (i) retail electricity and natural gas for residential, 
industrial and commercial consumers, including personal power solutions and Business Solutions, which includes C&I customers 
and other distributed and reliability products, and (ii) wholesale conventional generation primarily to support the retail business. 
The Company is committed to continuing to evaluate and streamline its generation portfolio to focus on locational value and 
supporting the retail business in each of the markets where the Company participates. In furtherance of this goal, during 2018, 
NRG divested non-core businesses which included, among others: (i) NRG Yield, Inc. and the Company's Renewables Platform, 
and (ii) the Company's South Central Portfolio.

 The Company previously had an ownership interest in GenOn Energy, Inc. which filed for bankruptcy on June 14, 2017. 
As a result of the bankruptcy filing, NRG determined it no longer controlled GenOn and deconsolidated GenOn and its subsidiaries 
for financial reporting purposes. On December 14, 2018, GenOn emerged from bankruptcy as a standalone company no longer 
owned by NRG. 

Retail 

Retail provides energy and related services to residential, industrial and commercial consumers through various brands 
and sales channels across the U.S. In 2018, Retail delivered approximately 67 TWhs of electricity and 11 MDth of natural gas 
and served approximately 3.1 million customers. Retail's results make it one of the largest competitive energy retailers in the 
U.S. As of the end of 2018, Retail has recurring electricity and/or natural gas sales in 19 U.S. states, the District of Columbia, 
and 2 provinces in Canada. Retail's brands, collectively, are the largest providers of electricity in Texas.

Residential  and  small  commercial  (Mass  Market)  consumers  make  purchase  decisions  based  on  a  variety  of  factors, 
including price, customer service, brand, product choices and value-added features. These consumers purchase products through 
a variety of sales channels, including direct sales, call centers, websites, brokers and brick-and-mortar stores. Through its broad 
range  of  service  offerings  and  value  propositions,  Retail  is  able  to  attract,  retain,  and  increase  the  value  of  its  customer 
relationships. Retail's brands are recognized for exemplary customer service, innovative smart energy and technology product 
offerings and environmentally friendly solutions. 

Included in Retail is the Company's Business Solutions group, which includes demand response, commodity sales, energy 
efficiency  and  energy  management  solutions. An  integrated  provider  of  supply  and  distributed  energy  resources,  Business 
Solutions focuses on distributed products and services as businesses seek greater reliability, cleaner power or other benefits that 
they cannot obtain from the grid. These solutions include system power, distributed generation, solar and wind products, carbon 
management and specialty services, backup generation, storage and distributed solar, demand response and energy efficiency 
and advisory services. In providing on-site energy solutions, the Company often benefits from its ability to supply energy products 
from its wholesale generation portfolio to commercial and industrial retail customers. In 2018, Business Solutions delivered 
approximately 21 TWhs of electricity and managed approximately 2,000 MWs of demand response positions across its portfolio.

Generation

The  Company’s  wholesale  power  generation  business  includes  plant  operations,  commercial  operations,  EPC,  asset 

management, energy services and other critical related functions.

The wholesale generation business is capital-intensive and commodity-driven with numerous industry participants that 
compete on the basis of the location of their plants, fuel mix, plant efficiency and  reliability services. The Company owns a 
diversified power generation portfolio with approximately 23,000(a) MW of fossil fuel, nuclear and renewable generation capacity 
at 37 plants as of December 31, 2018. In addition, the Company operates approximately 8,200 MW of coal and natural gas 
generation at 17 plants on behalf of third parties as of December 31, 2018. The Company's power generation assets are diversified 
by fuel-type, dispatch level and region, which helps mitigate the risks associated with fuel price volatility and market demand 
cycles. NRG's U.S. baseload and intermediate facilities provide the Company with a significant source of cash flow. Many of 
NRG's generation facilities are located near population centers, which often translates into higher revenue. Additionally, NRG's 
peaking facilities provide opportunities to capture significant upside potential during periods of high demand, which typically 
drive higher energy prices.

Wholesale power generation is a regional business that is currently highly fragmented and diverse in terms of industry 
structure. As such, there is a wide variation in terms of the capabilities, resources, nature and identities of the companies the 
Company competes with depending on the market. Competitors include regulated utilities, municipalities, cooperatives, other 
independent power producers, and power marketers or trading companies, including those owned by financial institutions. Many 
of the Company's generation assets, however, are located within densely populated areas that tend to have higher wholesale 
pricing as a result of relatively favorable local supply-demand balance. The Company believes that its extensive generation 
portfolio  provides  asset  optimization  opportunities.  NRG  continuously  evaluates  opportunities  for  development  of  new 
generation, on both a merchant and contracted basis.

NRG Operations

The NRG businesses described above are supported through the NRG operational infrastructure, which begins with the 
Company’s asset fleet and the associated commercial and retail operations. The images below illustrate NRG's U.S. power 
generation, net capacity and retail capabilities as of December 31, 2018, excluding discontinued operations:

The Company has the advantage of being able to supply its retail businesses with its own generation, which can reduce 
the need to sell and buy power from other institutions and intermediaries, resulting in lower transaction costs and credit exposures. 
This combination of generation and retail allows for a reduction in actual and contingent collateral, through offsetting transactions 
and by reducing the need to hedge the retail power supply through third parties.  

The generation and retail combination also provides stability in cash flows, as changes in commodity prices generally have 
offsetting impacts between the two businesses. This offsetting nature, in relation to changes in market prices, is an integral part 
of NRG's goal of providing a reliable source of future cash flow for the Company. 

NRG's portfolio diversification and commercial operations hedging strategy provides the Company with reliable future 
cash flows. NRG has hedged a portion of its coal and nuclear capacity with decreasing hedge levels through 2022. In addition, 
NRG's cleared capacity revenues not only enhance the reliability of future cash flows but are not correlated to natural gas prices 
during the contracted period. As of December 31, 2018, the Company had purchased fuel forward under fixed price contracts, 
with contractually-specified price escalators, for approximately 68% of its expected coal requirement from 2019 to 2020. The 
Company enters into additional hedges when it believes market conditions are favorable. 

Commercial Operations Overview

NRG seeks to maximize profitability and manage cash flow volatility through the marketing, trading and sale of energy, 
capacity and ancillary services into spot, intermediate and long-term markets and through the active management and trading 
of transmission rights, emissions allowances, renewable energy credits, fuel supplies and transportation-related services. The 
Company's principal objectives are the realization of the full market value of its overall portfolio, including the capture of its 
extrinsic value, the management and mitigation of commodity market risk and the reduction of cash flow volatility over time.

NRG enters into supply contracts, power sales and hedging arrangements via a wide range of products and contracts, 
including PPAs, fuel supply contracts, capacity auctions, natural gas derivative instruments and other financial instruments. In 
addition, because changes in power prices in the markets where NRG operates are generally correlated to changes in natural gas 
prices, NRG uses hedging strategies that may include power and natural gas forward purchases and sales contracts to manage 
the commodity price risk. The objective of these hedging strategies is to stabilize the cash flow generated by NRG's overall 
portfolio. 

12

In addition to power purchases and sales and hedging arrangements, NRG trades electric power, natural gas and related 
commodity and financial products, including forwards, futures, options and swaps. The Company seeks to generate profits from 
volatility in the price of electricity, capacity, fuels and transmission congestion by buying and selling contracts in wholesale 
markets under guidelines approved by the Company's risk management committee. 

Retail Operations

NRG's retail businesses sell electricity to residential, commercial and industrial consumers at either fixed, indexed or 
variable prices. Residential and smaller commercial consumers typically contract for terms ranging from one month to five years 
while industrial contracts are often between one year and five years in length. In 2018, NRG's retail businesses sold approximately 
67 TWhs of electricity and 11 MDth of natural gas. In any given year, the quantity of TWhs and MDth sold can be affected by 
weather, economic conditions and competition. The wholesale supply is typically purchased as the anticipated load is contracted 
from a combination of NRG's wholesale portfolio and other third parties. The ability to choose supply from the market or the 
Company's portfolio allows for an optimal combination to support and stabilize retail margins.

Capacity and Other Contracted Revenue Sources

NRG's revenues and cash flows benefit from capacity/demand payments and other contracted revenue sources, originating 
from  market  clearing  capacity  prices,  Resource Adequacy  contracts,  tolling  arrangements  and  other  long-term  contractual 
arrangements:  

Capacity auctions — The Company's largest sources of capacity revenues are capacity auctions in PJM and ISO-NE. Both 
PJM and ISO-NE operate a pay-for-performance model where capacity payments are modified based on real-time performance, 
where NRG's actual revenues will be the combination of revenues based on the cleared auction MWs plus the net of any over- 
and under-performance of NRG's fleet.

2021/2022 PJM Auction Results — On May 23, 2018, PJM announced the results of its 2021/2022 base residual 
auction.  NRG cleared approximately 4,619 MW of Capacity Performance product for the generation fleet. 
NRG's  expected  capacity  revenues  from  the  base  residual  auction  for  the  2021/2022  delivery  year  are 
approximately $322 million. The table below provides a detailed description of NRG’s 2021/2022 base residual 
auction results from May 23, 2018:

NRG through its demand response business received a capacity award of 3,194 MWs at a volume weighted 
average price of $155.16 per MW-day, or $181 million of revenue, and pays out a portion of these revenues 
to our customers reflected as cost of sales.

2022/2023 ISO-NE Auction Results - On February 6, 2019 ISO-NE announced the results of its 2022/2023 
forward capacity auction. NRG cleared 1,517 MW of capacity. NRG's expected capacity revenues from the 
auction for the 2022/2023 delivery year are approximately $69 million.

Resource adequacy and bilateral contracts — In California, there is a resource adequacy requirement which is primarily 
satisfied through bilateral contracts. Such bilateral contracts are typically short-term resource adequacy contracts. When bilateral 
contracting does not satisfy the resource adequacy need, such shortfalls can be addressed through procurement tools administered 
by the CAISO, including the capacity procurement mechanism or reliability must-run contracts.

Bilateral contracts — The Company enters into physical power bilateral contracts for the sale of energy from our generation 
fleet as part of the Company's portfolio optimization strategy. Counterparties to the contracts are either third parties or our Retail 
segment. The Company primarily sells physical capacity forward through bilateral contracts for our New York assets. To the 
extent NRG is not able to enter into a physical bilateral contract, NRG will sell the remaining capacity into the NYISO six month 
strip, monthly or spot auctions.

Fuel Supply and Transportation

NRG's fuel requirements consist of various forms of fossil fuel (including coal, natural gas and oil) and nuclear fuel. The 
prices of fossil fuels are highly volatile. The Company obtains its fossil fuels from multiple suppliers and through multiple 
transporters. Although availability is generally not an issue, localized shortages, transportation availability, delays arising from 
extreme weather conditions and supplier financial stability issues can and do occur. The preceding factors related to the sources 
and availability of raw materials are fairly uniform across the Company's businesses and fuel products used.

Coal — The  Company  believes  it  is  adequately  hedged,  using  forward  coal  supply  agreements,  for  its  domestic  coal 
consumption for 2019. NRG actively manages its coal requirements based on forecasted generation, market volatility and its 
inventory on site. As of December 31, 2018, NRG had purchased forward contracts to provide fuel for approximately 68% of 
the Company's expected requirements from 2019 through 2020. NRG purchased approximately 23 million tons of coal in 2018, 
almost all of which was Powder River Basin coal. For fuel transport, NRG has entered into various rail and barge transportation 
and rail car lease agreements with varying tenures that provide for most of the Company's transportation requirements of Powder 
River Basin coal for the next 2 years. 

The following table shows the percentage of the Company's coal requirements from 2019 through 2020 that have been 

purchased forward as of December 31, 2018:

2019
2020

Company's
Requirement

36%

Natural Gas — NRG operates a fleet of mid-merit and peaking natural gas plants across all its U.S. wholesale regions.  
Fuel needs are managed on a spot basis, especially for peaking assets, as the Company does not believe it is prudent to forward 
purchase natural gas for these types of units, the dispatch of which is highly unpredictable. The Company contracts for natural 
gas storage services as well as natural gas transportation services to deliver natural gas when needed.

Nuclear Fuel — STP's owners satisfy their fuel supply requirements by: (i) acquiring uranium concentrates and contracting 
for conversion of the uranium concentrates into uranium hexafluoride; (ii) contracting for enrichment of uranium hexafluoride; 
and (iii) contracting for fabrication of nuclear fuel assemblies. Through its proportionate participation in STPNOC, which is the 
NRC-licensed operator of STP and responsible for all aspects of fuel procurement, NRG is party to a number of long-term 
forward purchase contracts with many of the world's largest suppliers covering STP's requirements for uranium concentrates 
with only approximately 25% of STP's requirements outstanding for the duration of the original operating license. Similarly, 
NRG is party to long-term contracts to procure STP's requirements for conversion and enrichment services and fuel fabrication 
for the life of the operating license. Since the operating license was renewed for another 20 years in September 2017, STPNOC 
has begun to review a second phase of fuel purchasing.

Generation

The following are industry statistics for the Company's fossil and nuclear plants, as defined by the NERC, and are more 

fully described below:

Annual Equivalent Availability Factor, or EAF — Measures the percentage of maximum generation available over time 
as the fraction of net maximum generation that could be provided over a defined period of time after all types of outages and 
deratings, including seasonal deratings, are taken into account.

Net Heat Rate — The net heat rate represents the total amount of fuel in BTU required to generate one net kWh provided.

Net Capacity Factor — The net amount of electricity that a generating unit produces over a period of time divided by the 
net amount of electricity it could have produced if it had run at full power over that time period. The net amount of electricity 
produced is the total amount of electricity generated minus the amount of electricity used during generation.

The tables below present these performance metrics for the Company's global power generation portfolio, including leased 

facilities and those accounted for through equity method investments, for the years ended December 31, 2018 and 2017:

Greenhouse  Gas  Emissions  —  NRG  emits  CO2 and  small  quantities  of  other  GHGs  (0.6%  of  total)  when  generating 
electricity at a majority of its facilities. The graphs presented below illustrate NRG's domestic emissions of CO2e for the 2014 
through 2018 period. A significant majority (>99%) of NRG's emission sources are subject to federal (U.S. EPA) GHG reporting 
requirements programs. From 2014 to 2018, the Company's CO2e emissions decreased from 72 million metric tons to 46 million 
metric tons, representing a 36% reduction. The primary factor leading to the decreased emissions include reductions in fleet net 
generation due to a market-driven shift from coal as a primary fuel to natural gas. The Company's goal is to reduce CO2e emissions 
by 50% by 2030, and 90% by 2050, using 2014 as a baseline.

 As of December 31, 2018, less than 25% of the Company's consolidated operating revenues were derived from coal-fired 

operating assets.

The effects from federal, regional or state regulation of GHGs on the Company's financial performance will depend on a 

number of factors, including the outcome of the legal challenges and actions of the current U.S. presidential administration.

Seasonality and Price Volatility

Annual and quarterly operating results of the Company's wholesale power generation segments can be significantly affected 
by weather and energy commodity price volatility. Significant other events, such as the demand for natural gas, interruptions in 
fuel supply infrastructure and relative levels of hydroelectric capacity can increase seasonal fuel and power price volatility. The 
preceding factors related to seasonality and price volatility are fairly uniform across the Company's wholesale generation business 
segments.

The sale of electric power to retail customers is also a seasonal business with the demand for power generally peaking 
during the summer months. As a result, net working capital requirements for the Company's retail operations generally increase 
during summer months along with the higher revenues, and then decline during off-peak months. Weather may impact operating 
results and extreme weather conditions could materially affect results of operations. The rates charged to retail customers may 
be impacted by fluctuations in total power prices and market dynamics like the price of natural gas, transmission constraints, 
competitor actions, and changes in market heat rates.

Market Framework 

Retail 

NRG's retail businesses sell energy and related services as well as portable power and battery solutions to customers across 
the country. In most of the states that have introduced retail consumer choice, NRG's retail businesses competitively offer retail 
power, natural gas, portable power and other value-enhancing services to end-use customers. Each retail choice state establishes 
its own retail competition laws and regulations, and the specific operational, licensing, and compliance requirements vary on a 
state-by-state basis. In the East markets, incumbent utilities currently provide default service and as a result typically serve a 
majority of residential customers. In Texas, NRG’s retail business activities are subject to standards and regulations adopted by 
the PUCT and ERCOT, including the requirement for retailers to be certified by the PUCT in order to contract with end-users 
to sell electricity. A majority of the retail load is in the ERCOT market region and is served by competitive retail suppliers, 
except certain areas that are served by municipal utilities and electric cooperatives that have not opted into competitive choice. 
Regulated terms and conditions of default service, as well as any movement to replace default service with competitive services, 
as is done in ERCOT, can affect customer participation in retail competition. The attractiveness of NRG's retail offerings in each 
state  may  be  impacted  by  the  rules,  regulations,  market  structure  and  communication  requirements  from  public  utility 
commissions  in each state across the country.

Wholesale 

NRG's fleet operates in organized energy markets, known as RTOs or ISOs. Each organized market administers day-ahead 
and real-time centralized bid-based energy and ancillary services markets pursuant to tariffs approved by FERC, or in the case 
of ERCOT, market rules approved by the PUCT. These tariffs and rules dictate how the energy markets operate, how market 
participants make bilateral sales with one another, and how entities with market-based rates are compensated. Established prices 
reflect the value of energy at the specific location and time it is delivered, which is known as the Locational Marginal Price, or 
LMP. Each market is subject to market mitigation measures designed to limit the exercise of locational market power. These 
market structures facilitate NRG's sale of power and capacity products at market-based rates.    

Other than ERCOT, each of the ISO regions also operates a capacity or resource adequacy market that provides an opportunity 
for generating and demand response resources to earn revenues to offset their fixed costs that are not recovered in the energy 
and ancillary services markets. The ISOs are also responsible for transmission planning and operations.   

Texas  

NRG's Texas wholesale power generation business is located in the ERCOT market. The ERCOT market is one of the 
nation's largest and historically fastest growing power markets. ERCOT is an energy- only market, and has implemented market 
rule changes referred to as the Operating Reserve Demand Curve (ORDC) to provide pricing more reflective of higher energy 
value when operating reserves are scarce or constrained. The PUCT directed the implementation of the ORDC in 2014 to act 
as the primary scarcity pricing mechanism and has modified it several times since then, including as recently as January 2019.

19

East/West 

NRG's generation and demand response assets located in the East region of the U.S. are within the control areas of ISO-
NE, MISO, NYISO and PJM. Each of the market regions in the East region provides for robust competition in the day-ahead 
and real-time energy and ancillary services markets. Additionally, the East region receives a significant portion of its revenues 
from capacity markets in ISO-NE, MISO, NYISO and PJM. PJM and ISO-NE use a three-year forward capacity auction, while 
NYISO uses a month-ahead capacity auction. MISO has an annual auction, known as the Planning Resource Auction. Capacity 
market prices are sensitive to design parameters, as well as additions of new capacity. Both ISO-NE and PJM operate a pay-for-
performance model where capacity payments are modified based on real-time generator performance. In such markets, NRG’s 
actual revenues will be the combination of cleared auction prices times the quantity of MWs cleared, plus the net of any over-
performance "bonus payments" and any under-performance charges. In both markets, bidding rules allow for the incorporation 
of a risk premium into generator bids.

In the West region, NRG operates a fleet of natural gas fired facilities located entirely within the CAISO footprint. The 
CAISO  operates  day-ahead  and  real-time  locational  markets  for  energy  and  ancillary  services,  while  managing  congestion 
primarily through nodal prices. The CAISO system facilitates NRG's sale of power, ancillary services and capacity products at 
market-based rates, either within the CAISO's centralized energy and ancillary service markets or bilaterally pursuant to tolling 
arrangements or other capacity sales with California's LSEs. The CPUC also determines capacity requirements for LSEs and 
for specified local areas utilizing inputs from the CAISO. Both the CAISO and CPUC rules require LSEs to contract with 
sufficient generation resources in order to maintain minimum levels of generation within defined local areas. Additionally, the 
CAISO has independent authority to contract with needed resources under certain circumstances, typically either when LSEs 
have failed to procure sufficient resources, or system conditions change unexpectedly. 

The Company’s Agua Caliente and Ivanpah projects are party to PPAs with PG&E. Both projects have project financing 

with the U.S. DOE, and Agua Caliente Borrower 1 LLC, along with Agua Caliente Borrower 2 LLC, which is owned by 
Clearway Energy Inc., are party to a back leverage financing related to the Agua Caliente project. On January 29, 2019, 
PG&E Corp. and subsidiary utility PG&E filed for Chapter 11 bankruptcy protection. For further discussion see Item 1 - 
Energy Regulatory Matters, Note 11 - Debt and Capital Leases and Note 15 - Investments Accounted for by the Equity 
Method and Variable Interest Entities.

Energy Regulatory Matters 

As owners of power plants and participants in retail and wholesale energy markets, certain NRG entities are subject to 
regulation by various federal and state government agencies. These include the CFTC, FERC, NRC and the PUCT, as well as 
other public utility commissions in certain states where NRG's generating or distributed generation assets are located. In addition, 
NRG is subject to the market rules, procedures and protocols of the various ISO and RTO markets in which it participates. 
Likewise, certain NRG entities participating in the retail markets are subject to rules and regulations established by the states 
in which NRG entities are licensed to sell at retail. NRG must also comply with the mandatory reliability requirements imposed 
by NERC and the regional reliability entities in the regions where NRG operates.  

NRG's operations within the ERCOT footprint are not subject to rate regulation by FERC, as they are deemed to operate 
solely within the ERCOT market and not in interstate commerce. These operations are subject to regulation by the PUCT, as 
well as to regulation by the NRC with respect to NRG's ownership interest in STP.

Federal Energy Regulation

Complaints Ahead of PG&E Corporation Bankruptcy Filing — On January 18, 2019, NextEra filed a petition for declaratory 
order requesting that FERC assert its jurisdiction over PG&E's wholesale contracts prior to PG&E's formal bankruptcy filing. 
Exelon Corporation and EDF Renewables filed similar complaints. On January 25, 2019, FERC found that it and the bankruptcy 
courts have concurrent jurisdiction to review and address the disposition of wholesale power contracts. The matter is in litigation. 

State Energy Regulation

State Out-Of-Market Subsidy Proposals — NRG has opposed efforts to provide out-of-market subsidies and intends to 
continue opposing them in the future.   NRG has petitioned the Supreme Court of the United States to hear cases from the Seventh 
and Second Circuit Courts regarding ZECs in Illinois and New York, respectively. NRG is also currently participating in the 
NJBPU's proceeding regarding ZECs, and is involved in the informational meetings that the PA PUC is holding regarding the 
nuclear subsidy issue.

Regional Regulatory Developments

NRG is affected by rule/tariff changes that occur in the ISO regions. For further discussion on regulatory developments 

see Item 15 — Note 22, Regulatory Matters, to the Consolidated Financial Statements.

PJM 

Capacity Market Reforms Filing — FERC is considering various proposals to reform the PJM capacity market, including 
whether to accommodate state subsidies in the wholesale market or to mitigate subsidized resources, along with other changes. 
As part of this process, FERC established a procedural timetable and delayed the 2019 Base Residual Auction until August 2019. 
Decisions around harmonizing federal and state policy initiatives is a critical factor for setting future prices. 

New England

ISO-NE Retention of Mystic Units — ISO-NE is currently engaged in extensive litigation at FERC regarding how to ensure 
system reliability in a gas-constrained system. In particular, FERC has approved ISO-NE's proposal to retain units at the Mystic 
generating  station,  which  utilizes  liquefied  natural  gas  for  fuel  security. Among  other  things,  FERC  specifically  will  allow 
resources retained for fuel security to enter a zero bid in the Forward Capacity Auction. On January 2, 2019, multiple parties 
filed for rehearing. The motions for rehearing are pending at FERC. The outcome of this matter will potentially affect future 
capacity market prices. 

New York

Independent Power Producers of New York Complaint — A variety of generators have requested that FERC address the 
market impacts of out-of-market payments to existing generation in the NYISO. This request was prompted by the ZEC program 
initiated by the NYSPSC in 2013, with various requests for FERC to act since. The generators asked FERC to direct the NYISO 
to require that capacity from existing generation resources that would have exited the market but for out-of-market payments 
be mitigated. Failure to implement buyer-side mitigation measures could result in uneconomic entry, which artificially decreases 
capacity prices below competitive market levels.

New York Public Service Commission Retail Energy Market Proceedings — On February 23, 2016, the NYSPSC issued 
what it refers to as its "Retail Reset" order. Among other things, the Reset Order placed a price cap on energy supply offers and 
imposed burdensome new regulations on customers. Various parties have challenged the NYPSC's authority to regulate prices 
charged by competitive suppliers, and that litigation is ongoing.

Texas 

ORDC Reforms — In January 2019, the PUCT directed ERCOT to implement changes to its scarcity pricing structure, 
known as the ORDC, which is designed to increase the likelihood of scarcity pricing to support existing generation and new 
investment. The PUCT directed ORDC reforms to be implemented in two phases of gradually increasing magnitude. The first 
phase will become effective prior to the summer of 2019 and the second phase will become effective prior to the summer of 
2020.

Environmental Regulatory Matters  

NRG is subject to numerous environmental laws in the development, construction, ownership and operation of projects. 
These laws generally require that governmental permits and approvals be obtained before construction and during operation of 
power plants. Federal and state environmental laws historically have become more stringent over time. Future laws may require 
the addition of emissions controls or other environmental controls or impose restrictions on our operations, which could affect 
the Company's operations. Complying with environmental laws often involves significant capital and operating expenses, as 
well as occasionally curtailing operations. NRG decides to invest capital for environmental controls based on the relative certainty 
of the requirements, an evaluation of compliance options, and the expected economic returns on capital.  

A number of regulations that may affect the Company are under review by the EPA, including ESPS for GHGs, ash disposal 
requirements, NAAQS revisions and implementation and effluent limitation guidelines. NRG will evaluate the impact of these 
regulations as they are revised but cannot fully predict the impact of each until anticipated revisions and legal challenges are 
resolved.  

21

Air 

The CAA and the resulting regulations (as well as similar state and local requirements) have the potential to affect air 
emissions, operating practices and pollution control equipment required at power plants. Under the CAA, the EPA sets NAAQS 
for certain pollutants including SO2, ozone, and PM2.5. Many of the Company's facilities are located in or near areas that are 
classified by the EPA as not achieving certain NAAQS (non-attainment areas). The relevant NAAQS have become more stringent. 
The Company maintains a comprehensive compliance strategy to address continuing and new requirements. Complying with 
increasingly stringent air regulations could require the installation of additional emissions control equipment at some NRG 
facilities or retiring of units if installing such controls is not economic. Significant changes to air regulatory programs affecting 
the Company are described below. 

MATS — In 2012, the EPA promulgated standards (the MATS rule) to control emissions of HAPs from coal and oil-fired 
electric generating units. The rule established limits for mercury, non-mercury metals, certain organics and acid gases, which 
had to be met beginning in April 2015. In December 2018, the EPA proposed a finding that regulating HAPs was not "appropriate 
and necessary" because the costs far exceed the benefits. Nonetheless, the EPA proposed keeping the substantive requirements 
of the MATS rule. While NRG cannot predict the final outcome of this rulemaking, NRG believes that because it has already 
invested in pollution controls and cleaner technologies, the fleet is well-positioned to comply with the MATS rule.

Clean Power Plan — The attention in recent years on GHG emissions has resulted in federal regulations and state legislative 
and regulatory action. In October 2015, the EPA finalized the CPP, addressing GHG emissions from existing EGUs. On February 
9, 2016, the U.S. Supreme Court stayed the CPP. The D.C. Circuit heard oral argument on the legal challenges to the CPP in 
September 2016. At the EPA's request, the D.C. Circuit agreed on April 28, 2017 to hold the case in abeyance. On October 16, 
2017, the EPA proposed a rule to repeal the CPP. In August 2018, the EPA published the proposed Affordable Clean Energy, or 
ACE, rule to replace the CPP. The ACE rule proposes that the EPA would provide guidelines for states to in turn require heat 
rate improvements at coal-fired EGUs to reduce GHG emissions.

 Byproducts, Wastes, Hazardous Materials and Contamination

In April 2015, the EPA finalized the rule regulating byproducts of coal combustion (e.g., ash and gypsum) as solid wastes 
under the RCRA. In September 2017, the EPA agreed to reconsider the rule. On July 30, 2018, the EPA promulgated a rule that 
amends the existing ash rule by extending some of the deadlines and providing more flexibility for compliance. On August 21, 
2018, the D.C. Circuit found, among other things, that the EPA had not adequately regulated unlined ponds and legacy ponds. 
Accordingly, we anticipate that the EPA will promulgate new regulations to address these issues (including compliance deadlines) 
as it reconsiders other aspects of the existing rule. The EPA has stated that it intends to further revise the rule. The Company 
will provide estimates of the cost of compliance after the rule is revised. 

Domestic Site Remediation Matters

Under certain federal, state and local environmental laws, a current or previous owner or operator of a facility, including 
an electric generating facility, may be required to investigate and remediate releases or threatened releases of hazardous or toxic 
substances  or  petroleum  products.  NRG  may  be  responsible  for  property  damage,  personal  injury  and  investigation  and 
remediation costs incurred by a party in connection with hazardous material releases or threatened releases. These laws impose 
liability without regard to whether the owner knew of or caused the presence of the hazardous substances, and the courts have 
interpreted liability under such laws to be strict (without fault) and joint and several. Cleanup obligations can often be triggered 
during the closure or decommissioning of a facility, in addition to spills during its operations. Further discussions of affected 
NRG sites can be found in Item 15 — Note 23, Environmental Matters, to the Consolidated Financial Statements.

Nuclear Waste — The federal government's program to construct a nuclear waste repository at Yucca Mountain, Nevada 
was discontinued in 2010. Since 1998, the U.S. DOE has been in default of the federal government's obligations to begin accepting 
spent nuclear fuel, or SNF, and high-level radioactive waste, or HLW, under the Nuclear Waste Policy Act. Owners of nuclear 
plants, including the owners of STP, had been required to enter into contracts setting out the obligations of the owners and the 
U.S. DOE, including the fees to be paid by the owners for the U.S. DOE's services to license a spent fuel repository. Effective 
May 16, 2014, the U.S. DOE stopped collecting the fees.  

22

On February 5, 2013, STPNOC entered into a settlement agreement with the U.S. DOE for payment of damages relating 
to the U.S. DOE's failure to accept SNF and HLW under the Nuclear Waste Policy Act through December 31, 2013, which was 
extended through an addendum dated January 24, 2014, to December 31, 2016. On December 12, 2016, STPNOC received the 
federal government's offer of another three-year extension of payment for continued failure to accept SNF and HLW. The proposal 
was reviewed and accepted. There are no facilities for the reprocessing or permanent disposal of SNF currently in operation in 
the U.S., nor has the NRC licensed any such facilities. STPNOC currently stores all SNF generated by its nuclear generating 
facilities in on-site storage pools. Since STPNOC's SNF storage pools do not have sufficient storage capacity for the life of the 
units, STPNOC is proceeding to construct dry cask storage capability on-site. STPNOC plans to continue to assert claims against 
the U.S. DOE for damages relating to the U.S. DOE's failure to accept SNF and HLW.

Under the federal Low-Level Radioactive Waste Policy Act of 1980, as amended, the state of Texas is required to provide, 
either on its own or jointly with other states in a compact, for the disposal of all low-level radioactive waste generated within 
the state.  STP's warehouse capacity is adequate for on-site storage until a site in Andrews County, Texas becomes fully operational. 

Water 

The Company is required under the CWA to comply with intake and discharge requirements, requirements for technological 
controls and operating practices. As with air quality regulations, federal and state water regulations have become more stringent 
and imposed new requirements.  

Once Through Cooling Regulation — In August 2014, EPA finalized the regulation regarding the use of water for once 
through  cooling  at  existing  facilities  to  address  impingement  and  entrainment  concerns. While  NRG  anticipates  that  more 
stringent requirements will be incorporated into some of its water discharge permits over the next several years as NPDES 
permits are renewed, the Company anticipates the cost of complying with these restrictions to be immaterial.

Effluent Limitations Guidelines — In November 2015, the EPA revised the Effluent Limitations Guidelines for Steam 
Electric Generating Facilities, which would have imposed more stringent requirements (as individual permits were renewed) 
for wastewater streams from flue gas desulfurization, fly ash, bottom ash, and flue gas mercury control. In April 2017, the EPA 
granted two petitions to reconsider the rule and also administratively stayed some of the deadlines. On September 18, 2017, the 
EPA promulgated a final rule that (i) postpones the compliance dates to preserve the status quo for FGD wastewater and bottom 
ash transport water by two years to November 2020 until the EPA completes its next rulemaking and (ii) withdrew the April 
2017 administrative stay. The legal challenges have been suspended while the EPA reconsiders and likely modifies the rule. 
Accordingly, the Company has eliminated its estimate of the environmental capital expenditures that would have been required 
to comply with permits incorporating the revised guidelines. The Company will revisit these estimates after the rule is revised. 

Regional Environmental Developments

Burton Island Old Ash Landfill — In January 2006, NRG's Indian River Power LLC was notified that it may be a potentially 
responsible party with respect to Burton Island Old Ash Landfill, a historic captive landfill located at the Indian River facility. 
On October 1, 2007, NRG signed an agreement with DNREC to investigate the site through the Voluntary Clean-up Program, 
or the VCP. On February 4, 2008, DNREC issued findings that no further action was required in relation to surface water and 
that a previously planned shoreline stabilization project would satisfactorily address shoreline erosion. The landfill itself required 
a  Remedial  Investigation  and  Feasibility  Study  to  determine  the  type  and  scope  of  any  additional  required  work.  DNREC 
approved the Feasibility Study in December 2012. In January 2013, DNREC proposed a remediation plan based on the Feasibility 
Study. The remediation plan was approved in October 2013. In December 2015, DNREC approved the Company's remediation 
design,  the  Company's  Closure  Report  and  the  Company's  Long Term  Stewardship  Plan. The  cost  of  completing  the  work 
required by the approved remediation plan is consistent with amounts budgeted in early 2016 and remediation was completed 
in 2017. The estimated cost to comply with the Long-Term Stewardship Plan was added to the liability in 2016.  

In  addition  to  the VCP,  on  May  29,  2008,  DNREC  requested  that  NRG's  Indian  River  Power  LLC  participate  in  the 
development and performance of a Natural Resource Damage Assessment at the Burton Island Old Ash Landfill. NRG is working 
with DNREC and other trustees to close out the assessment process. 

Customers

NRG sells to a wide variety of customers. ERCOT accounted for 11% of NRG's total revenue in 2018. The Company owns 
and operates power plants to generate and sell power to wholesale customers such as utilities and other intermediaries. The 
Company  also  directly  sells  to  end-use  customers  in  the  residential,  commercial  and  industrial  sectors.  NRG  also  receives 
significant revenues from PJM in its capacity as the regional transmission organization for the PJM footprint.

23

Employees

As of December 31, 2018, NRG and its consolidated subsidiaries had 4,862 employees, approximately 26% of whom were 
covered by U.S. bargaining agreements. During 2018, the Company did not experience any labor stoppages or labor disputes 
at any of its facilities.

Available Information

NRG's annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to 
those reports filed or furnished pursuant to section 13(a) or 15(d) of the Exchange Act are available free of charge through the

Item 1A — Risk Factors Related to NRG Energy, Inc.

Risks Related to the Operation of NRG's Business

NRG adopted and initiated the Transformation Plan. If the Transformation Plan does not achieve its expected benefits, there 
could be negative impacts to NRG’s business, results of operations and financial condition. 

NRG adopted and initiated the Transformation Plan, designed to significantly strengthen earnings and cost competitiveness, 
lower risk and volatility, and create significant shareholder value. The three-part, three-year plan is comprised of the following 
components: (i) operations and cost excellence; (ii) portfolio optimization; and (iii) capital structure and allocation enhancements.

NRG may be unable to fully implement the components of the Transformation Plan, in which case, NRG would not realize 
the anticipated benefits. Alternatively, such components of the Transformation Plan, even if implemented, may not result in the 
anticipated benefits to NRG’s business, results of operations and financial condition in a timely manner if at all. Further, NRG 
could  experience  unexpected  delays,  business  disruptions  resulting  from  supporting  these  initiatives  during  and  following 
completion of these activities, decreased productivity, adverse effects on employee morale and employee turnover as a result of 
such initiatives, any of which may impair NRG’s ability to achieve anticipated results or otherwise harm NRG’s business, results 
of operations and financial condition. 

NRG's financial performance may be impacted by price fluctuations in the retail and wholesale power and natural gas markets, 
as well as fluctuations in coal and oil markets and other market factors that are beyond the Company's control.

Market  prices  for  power,  capacity,  ancillary  services,  natural  gas,  coal  and  oil  are  unpredictable  and  tend  to  fluctuate 
substantially. Unlike most other commodities, electric power can only be stored on a very limited basis and generally must be 
produced  concurrently  with  its  use. As  a  result,  power  prices  are  subject  to  significant  volatility  due  to  supply  and  demand 
imbalances, especially in the day-ahead and spot markets. Long- and short-term power prices may also fluctuate substantially due 
to other factors outside of the Company's control, including:

• 

• 

• 

• 

• 

• 

changes in generation capacity in the Company’s markets, including the addition of new supplies of power as a result of 
the development of new plants, expansion of existing plants, the continued operation of uneconomic power plants due 
to state subsidies, or additional transmission capacity;

environmental regulations and legislation;

electric supply disruptions, including plant outages and transmission disruptions;

changes in power transmission infrastructure;

fuel transportation capacity constraints or inefficiencies;

changes in law, including judicial decisions;

•  weather conditions, including extreme weather conditions and seasonal fluctuations, including the effects of climate 

change;

• 

• 

• 

• 

• 

• 

• 

• 

• 

changes in commodity prices and the supply of commodities, including but not limited to natural gas, coal and oil;

changes in the demand for power or in patterns of power usage, including the potential development of demand-side 
management tools and practices, distributed generation, and more efficient end-use technologies;

development of new fuels, new technologies and new forms of competition for the production of power;

fuel price volatility;

economic and political conditions;

regulations and actions of the ISOs and RTOs; 

federal and state power regulations and legislation;

changes in prices related to RECs; and

changes in capacity prices and capacity markets.

While retail rates are generally designed to allow retail sellers of electricity and natural gas to pass through price fluctuations, 
the Company may not be able to pass through all such fluctuations to customers.  For example, the Company engages in some 
sales of power at fixed prices.  Additionally, increases in wholesale costs to retail customers may cause additional customer defaults 
or increased customer attrition, or may be limited by regulatory rules.    

25

Such factors and the associated fluctuations in power prices have affected the Company's wholesale and retail profitability  

in the past and will continue to do so in the future.

Some of NRG's businesses operate, wholly or partially, without long-term power sale agreements.

Some of NRG's businesses operate without long-term contracts.  In retail, many of NRG’s customers are contracted for a 
period of one year or less, and NRG may or may not hedge its retail power sales exposure, or may hedge in a manner that is not 
effective at managing quantity or price risk in the retail market.  In generation, many of NRG’s facilities operate as "merchant" 
facilities without long-term power sales agreements for some or all of their generating capacity and output and therefore are 
exposed to market fluctuations. Without the benefit of long-term power sales or purchase agreements, and without long-term load 
obligations, NRG cannot be sure that it will be able to sell or purchase power at commercially attractive rates or that its generation 
facilities will be able to operate profitably. This could lead to future impairments of the Company's property, plant and equipment, 
the closing of certain of its facilities or the loss of retail customers, which could have a material adverse effect on the Company's 
results of operations, financial condition or cash flows.

The Company's retail businesses may lose a significant number of retail customers due to competitive marketing activity by 
other retail electricity providers which could adversely affect the financial performance of the Company's retail businesses. 

The Company's retail businesses face competition for customers.  Competitors may offer different products, lower prices, 
and other incentives, which may attract customers away from NRG's retail businesses.  In some retail electricity markets, the 
principal competitor may be the incumbent utility.  The incumbent utility has the advantage of long-standing relationships with 
its customers and strong brand recognition.  Furthermore, NRG's retail businesses may face competition from a number of other 
energy service providers, other energy industry participants, or nationally branded providers of consumer products and services, 
who may develop businesses that will compete with NRG and its retail businesses. 

NRG's costs, results of operations, financial condition and cash flows could be adversely impacted by disruption of its fuel 
supplies.

NRG relies on natural gas, coal and oil to fuel a majority of its power generation facilities. Its retail operations can likewise 
be affected by changes in commodity costs. Grid operations depend on the continuing financial viability of contractual counterparties 
as well as upon the infrastructure (including rail lines, rail cars, barge facilities, roadways, riverways and natural gas pipelines) 
available to serve generation facilities and to ensure that there is sufficient power produced to meet retail demand. As a result, the 
Company’s wholesale generating facilities are subject to the risks of disruptions or curtailments in the production of power at its 
generation facilities if no fuel is available at any price or if a counterparty fails to perform or if there is a disruption in the fuel 
delivery infrastructure.  The Company’s retail operations are likewise subject to many of the same constraints.

NRG routinely hedges both its wholesale sales and purchases to support its retail load obligations.  In order to hedge these 
obligations, the Company may enter into long-term and short-term contracts for the purchase and delivery of fuel. Many of the 
forward power sales contracts do not allow the Company to pass through changes in fuel costs or discharge the power sale obligations 
in the case of a disruption in fuel supply due to force majeure events or the default of a fuel supplier or transporter. Disruptions 
in the Company's fuel supplies or power supply arrangements may therefore require it to find alternative fuel sources at higher 
costs, to find other sources of power to deliver to retail customers or other counterparties at a higher cost, or to pay damages to 
counterparties for failure to deliver power or sell electricity or natural gas as contracted. Any such event could have a material 
adverse effect on the Company's financial performance.

26

NRG also buys significant quantities of electricity and fuel on a short-term or spot market basis. Prices sometimes rise or 
fall  significantly over a relatively short period of time. The price NRG can obtain for the sale of energy may not rise at the same 
rate, or may not rise at all, to match a rise in fuel or delivery costs. Retail rates may also not rise at the same rate, or may not rise 
at all. This may have a material adverse effect on the Company's financial performance. Changes in market prices for electricity, 
natural gas, coal and oil may result from the following:

•  weather conditions;

• 

• 

• 

• 

• 

• 

• 

• 

• 

seasonality;

demand for energy commodities and general economic conditions;

disruption or other constraints or inefficiencies of electricity, gas or coal transmission or transportation;

additional generating capacity;

availability and levels of storage and inventory for fuel stocks;

natural gas, crude oil, refined products and coal production levels;

changes in market liquidity;

federal, state and foreign governmental regulation and legislation; and

the creditworthiness and liquidity and willingness of fuel suppliers/transporters to do business with the Company.

NRG's plant operating characteristics and equipment, particularly at its coal-fired plants, often dictate the specific fuel quality 
to be combusted. The availability and price of specific fuel qualities may vary due to supplier financial or operational disruptions, 
transportation disruptions and force majeure. At times, coal of specific quality may not be available at any price, or the Company 
may not be able to transport such coal to its facilities on a timely basis. In this case, the Company may not be able to run the coal 
facility even if it would be profitable. Operating a coal facility with different quality coal can lead to emission or operating problems. 
If the Company had sold forward the power from such a coal facility, it could be required to supply or purchase power from 
alternate sources, perhaps at a loss. This could have a material adverse impact on the financial results of specific plants and on the 
Company's results of operations.

Changes in the price of coal and natural gas could cause the Company to hold excess coal inventories and incur contract 
termination costs. 

Low natural gas prices can cause natural gas to be the more cost-competitive fuel compared to coal for generating electricity. 
Because the Company enters into guaranteed supply contracts to provide for the amount of coal needed to operate its base load 
coal-fired generating facilities, the Company may experience periods where it holds excess amounts of coal if fuel pricing results 
in the Company reducing or idling coal-fired generating facilities. In addition, the Company may incur costs to terminate supply 
contracts for coal in excess of its generating requirements. 

Volatile power supply costs and demand for power could adversely affect the financial performance of NRG's retail businesses.

Although NRG is the primary provider of its retail businesses' wholesale electricity supply requirements, the retail businesses 
purchase a significant portion of their supply requirements from third parties. As a result, financial performance depends on the 
ability to obtain adequate supplies of electric generation from third parties at prices below the prices it charges its customers. 
Consequently, the Company's earnings and cash flows could be adversely affected in any period in which the retail businesses' 
wholesale electricity supply costs rise at a greater rate than the rates it charges to customers. The price of wholesale electricity 
supply purchases associated with the retail businesses' energy commitments can be different than that reflected in the rates charged 
to customers due to, among other factors:

• 

• 

• 

• 

• 

varying supply procurement contracts used and the timing of entering into related contracts;

subsequent changes in the overall price of natural gas;

daily, monthly or seasonal fluctuations in the price of natural gas relative to the 12-month forward prices;

transmission constraints and the Company's ability to move power to its customers; and

changes in market heat rate (i.e., the relationship between power and natural gas prices).

The retail businesses' earnings and cash flows could also be adversely affected in any period in which its customers' actual 
usage of electricity significantly varies from the forecasted usage, which could occur due to, among other factors, weather events, 
competition and economic conditions.

27

NRG's trading operations and use of hedging agreements could result in financial losses that negatively impact its results of 
operations.

The Company typically enters into hedging agreements, including contracts to purchase or sell commodities at future dates 
and at fixed prices, to manage the commodity price risks inherent in its power generation and retail operations. The Company’s 
risk management policies and hedging procedures may not mitigate risk as planned, and the Company may fail to fully or effectively 
hedge its commodity supply and price risk. In addition, these activities, although intended to mitigate price volatility, expose the 
Company to other risks. When the Company sells or buys power forward, it gives up the opportunity to buy or sell power at the 
future price, which not only may result in lost opportunity costs but also may require the Company to post significant amounts of 
cash collateral or other credit support to its counterparties. The Company also relies on counterparty performance under its hedging 
agreements and is exposed to the credit quality of its counterparties under those agreements. Further, if the values of the financial 
contracts change in a manner that the Company does not anticipate, or if a counterparty fails to perform under a contract, it could 
harm the Company's business, operating results or financial position.

NRG does not typically hedge the entire exposure of its operations against commodity price volatility. To the extent it does 
not hedge against commodity price volatility, the Company's results of operations and financial position may be improved or 
diminished based upon movement in commodity prices.

NRG may engage in trading activities, including the trading of power, fuel and emissions allowances that are not directly 
related to the operation of the Company's generation facilities or the management of related risks. These trading activities take 
place in volatile markets and some of these trades could be characterized as speculative. The Company would expect to settle 
these trades financially rather than through the production of power or the delivery of fuel. This trading activity may expose the 
Company to the risk of significant financial losses which could have a material adverse effect on its business and financial condition.

There may be periods when NRG will not be able to meet its commitments under forward sale or purchase obligations at a 
reasonable cost or at all.

The Company may sell fixed price gas as a proxy for power. Because the obligations under most of these agreements are 
not contingent on a unit being available to generate power, NRG is generally required to deliver power to the buyer, even in the 
event of a plant outage, fuel supply disruption or a reduction in the available capacity of the unit. To the extent that the Company 
does not have sufficient lower-cost capacity to meet its commitments under its forward sale obligations, the Company would be 
required to supply replacement power either by running its other, higher cost power plants or by obtaining power from third-party 
sources at market prices that could substantially exceed the contract price. If NRG fails to deliver the contracted power, it would 
be required to pay the difference between the market price at the delivery point and the contract price, and the amount of such 
payments could be substantial.

NRG's trading operations and use of hedging agreements could result in financial losses that negatively impact its results of 
operations.

The Company typically enters into hedging agreements, including contracts to purchase or sell commodities at future dates 
and at fixed prices, to manage the commodity price risks inherent in its power generation and retail operations. These activities, 
although intended to mitigate price volatility, expose the Company to other risks. When the Company sells or buys power forward, 
it gives up the opportunity to buy or sell power at the future price, which not only may result in lost opportunity costs but also 
may require the Company to post significant amounts of cash collateral or other credit support to its counterparties. The Company 
also relies on counterparty performance under its hedging agreements and is exposed to the credit quality of its counterparties 
under those agreements. Further, if the values of the financial contracts change in a manner that the Company does not anticipate, 
or if a counterparty fails to perform under a contract, it could harm the Company's business, operating results or financial position.

NRG does not typically hedge the entire exposure of its operations against commodity price volatility. To the extent it does 
not hedge against commodity price volatility, the Company's results of operations and financial position may be improved or 
diminished based upon movement in commodity prices.

NRG may engage in trading activities, including the trading of power, fuel and emissions allowances that are not directly 
related to the operation of the Company's generation facilities or the management of related risks. These trading activities take 
place in volatile markets and some of these trades could be characterized as speculative. The Company would expect to settle 
these trades financially rather than through the production of power or the delivery of fuel. This trading activity may expose the 
Company to the risk of significant financial losses which could have a material adverse effect on its business and financial condition.

28

NRG may not have sufficient liquidity to hedge market risks effectively.

The Company is exposed to market risks through its retail and wholesale business, which involves the purchase of electricity 
for resale, the sale of energy, capacity and related products, and the purchase and sale of fuel, transmission services and emission 
allowances. These market risks include, among other risks, volatility arising from location and timing differences that may be 
associated with buying and transporting fuel, converting fuel into energy and delivering energy to a buyer.

NRG  undertakes  these  marketing  activities  through  agreements  with  various  counterparties.  Many  of  the  Company's 
agreements with counterparties include provisions that require the Company to provide guarantees, offset or netting arrangements, 
letters of credit, a first lien on assets and/or cash collateral to protect the counterparties against the risk of the Company's default 
or insolvency. The amount of such credit support that must be provided typically is based on the difference between the price of 
the commodity in a given contract and the market price of the commodity. Significant movements in market prices can result in 
the Company being required to provide cash collateral and letters of credit in very large amounts. The effectiveness of the Company's 
strategy may depend on the amount of collateral available to enter into or maintain these contracts, and liquidity requirements may 
be greater than the Company anticipates or will be able to meet. Without a sufficient amount of working capital to post as collateral 
in support of performance guarantees or as a cash margin, the Company may not be able to manage price volatility effectively or 
to implement its strategy. An increase in the amount of letters of credit or cash collateral required to be provided to the Company's 
counterparties may negatively affect the Company's liquidity and financial condition.

Further, if any of NRG's facilities experience unplanned outages, or if retail customers use more power than expected, the 
Company may be required to procure additional power at spot market prices to fulfill contractual commitments. Without adequate 
liquidity to meet margin and collateral requirements, the Company may be exposed to significant losses, may miss significant 
opportunities, and may have increased exposure to the volatility of spot markets.

The accounting for NRG's hedging activities may increase the volatility in the Company's quarterly and annual financial 
results.

NRG engages in commodity-related marketing and price-risk management activities in order to financially hedge its exposure 
to market risk with respect to electricity sales from its generation assets, fuel utilized by those assets and emission allowances, as 
well as retail sales of electricity.

NRG generally attempts to balance its fixed-price physical and financial purchases and sales commitments in terms of 
contract volumes and the timing of performance and delivery obligations through the use of financial and physical derivative 
contracts. These derivatives are accounted for in accordance with the FASB ASC 815, Derivatives and Hedging, or ASC 815, 
which requires the Company to record all derivatives on the balance sheet at fair value with changes in the fair value resulting 
from fluctuations in the underlying commodity prices immediately recognized in earnings, unless the derivative qualifies for cash 
flow hedge accounting treatment. Whether a derivative qualifies for cash flow hedge accounting treatment depends upon it meeting 
specific criteria used to determine if the cash flow hedge is and will remain appropriate for the term of the derivative. All economic 
hedges may not necessarily qualify for cash flow hedge accounting treatment. As a result, the Company's quarterly and annual 
results are subject to significant fluctuations caused by changes in market prices.

Competition in power markets may have a material adverse effect on NRG's results of operations, cash flows and the market 
value of its assets.

NRG has numerous competitors in all aspects of its business, and additional competitors may enter the industry. New parties 

may offer retail electricity bundled with other products or at prices that are below the Company’s rates.  

Because many of the Company's facilities are older, newer plants owned by the Company's competitors are often more 
efficient than NRG's aging plants, which may put some of the Company's plants at a competitive disadvantage to the extent the 
Company's competitors are able to consume the same or less fuel as the Company's plants consume. Over time, the Company's 
plants may be squeezed out of their markets or may be unable to compete with these more efficient plants.

Other companies with which NRG competes may have greater liquidity, greater access to credit and other financial resources, 
lower cost structures, more effective risk management policies and procedures, greater ability to incur losses, longer-standing 
relationships with customers, greater potential for profitability from retail sales or greater flexibility in the timing of their sale of 
generation capacity and ancillary services than NRG does. Competitors may also have better access to subsidies or other out-of-
market payments that put NRG at a competitive disadvantage.

29

NRG's competitors may be able to respond more quickly to new laws or regulations or emerging technologies, or to devote 
greater resources to marketing of retail power than NRG can. In addition, current and potential competitors may make strategic 
acquisitions or establish cooperative relationships among themselves or with third parties. Accordingly, it is possible that new 
competitors or alliances among current and new competitors may emerge and rapidly gain significant market share. There can be 
no assurance that NRG will be able to compete successfully against current and future competitors, and any failure to do so would 
have a material adverse effect on the Company's business, financial condition, results of operations and cash flow.

Operation of power generation facilities involves significant risks and hazards customary to the power industry that could have 
a material adverse effect on NRG's revenues and results of operations, and NRG may not have adequate insurance to cover 
these risks and hazards.

The ongoing operation of NRG's facilities involves risks that include the breakdown or failure of equipment or processes, 
performance below expected levels of output or efficiency and the inability to transport the Company's product to its customers 
in an efficient manner due to a lack of transmission capacity. Unplanned outages of generating units, including extensions of 
scheduled outages due to mechanical failures or other problems occur from time to time and are an inherent risk of the Company's 
business. Unplanned outages typically increase the Company's operation and maintenance expenses and may reduce the Company's 
revenues as a result of selling fewer MWh or non-performance penalties or require NRG to incur significant costs as a result of 
running one of its higher cost units or obtaining replacement power from third parties in the open market to satisfy the Company's 
forward power sales obligations. NRG's inability to operate the Company's plants efficiently, manage capital expenditures and 
costs, and generate earnings and cash flow from the Company's asset-based businesses could have a material adverse effect on 
the Company's results of operations, financial condition or cash flows. While NRG maintains insurance, obtains warranties from 
vendors and obligates contractors to meet certain performance levels, the proceeds of such insurance, warranties or performance 
guarantees may not be adequate to cover the Company's lost revenues, increased expenses or liquidated damages payments should 
the Company experience equipment breakdown or non-performance by contractors or vendors.

In addition, NRG provides plant operations and commercial services to a variety of third-parties. There is a risk that mistakes, 
mis-operations, or actions taken by these third-parties could be attributed to NRG, including the risk of investigation or penalties 
being assessed to NRG in connection with the services it offers, or that regulators could question whether NRG had the appropriate 
safeguards in place.

Power generation involves hazardous activities, including acquiring, transporting and unloading fuel, operating large pieces 
of  rotating  equipment  and  delivering  electricity  to  transmission  and  distribution  systems.  In  addition  to  natural  risks  such  as 
earthquake, flood, lightning, hurricane and wind, other hazards, such as fire, explosion, structural collapse and machinery failure 
are inherent risks in the Company's operations. These and other hazards can cause significant personal injury or loss of life, severe 
damage to and destruction of property, plant and equipment, contamination of, or damage to, the environment and suspension of 
operations. The occurrence of any one of these events may result in NRG being named as a defendant in lawsuits asserting claims 
for substantial damages, including for environmental cleanup costs, personal injury and property damage and fines and/or penalties. 
NRG maintains an amount of insurance protection that it considers adequate, but the Company cannot provide any assurance that 
its insurance will be sufficient or effective under all circumstances and against all hazards or liabilities to which it may be subject. 
A successful claim for which the Company is not fully insured could hurt its financial results and materially harm NRG's financial 
condition. NRG cannot provide any assurance that its insurance coverage will continue to be available at all or at rates or on terms 
similar to those presently available. Any losses not covered by insurance could have a material adverse effect on the Company's 
financial condition, results of operations or cash flows.

Maintenance,  expansion  and  refurbishment  of  power  generation  facilities  involve  significant  risks  that  could  result  in 
unplanned power outages or reduced output and could have a material adverse effect on NRG's results of operations, cash 
flows and financial condition.

Many of NRG's facilities require periodic maintenance and repair. Any unexpected failure, including failure associated with 

breakdowns, forced outages or any unanticipated capital expenditures could result in reduced profitability.

NRG cannot be certain of the level of capital expenditures that will be required due to changing environmental and safety 
laws (including changes in the interpretation or enforcement thereof), needed facility repairs and unexpected events (such as natural 
disasters or terrorist attacks). The unexpected requirement of large capital expenditures could have a material adverse effect on 
the Company's liquidity and financial condition.

If NRG significantly modifies a unit, the Company may be required to install the best available control technology or to 
achieve the lowest achievable emission rates as such terms are defined under the new source review provisions of the CAA, which 
would likely result in substantial additional capital expenditures.

30

NRG and its subsidiaries have guaranteed the performance of third parties, which may result in substantial costs in the event 
of non-performance. 

NRG and its subsidiaries have issued certain guarantees of the performance of others, which obligate NRG and its subsidiaries 
to perform in the event that the third parties do not perform. In the event of non-performance by the third parties, NRG could incur 
substantial cost to fulfill their obligations under these guarantees. Such performance guarantees could have a material impact on 
the operating results, financial condition, or cash flows of the Company. 

Supplier and/or customer concentration at certain of NRG's facilities may expose the Company to significant financial credit 
or performance risks.

NRG often relies on a single contracted supplier or a small number of suppliers for the provision of fuel, transportation of 
fuel, chemicals and other services required for the operation of certain of its facilities. If these suppliers cannot perform, the 
Company utilizes the marketplace to provide these services. There can be no assurance that the marketplace can provide these 
services as, when and where required or at comparable prices.

At times, NRG may rely on a single customer or a few customers to purchase all or a significant portion of a facility's output, 
in some cases under long-term agreements that account for a substantial percentage of the anticipated revenue from a given facility. 
The Company has also hedged a portion of its exposure to power price fluctuations through forward fixed price power sales and 
natural gas price swap agreements. Counterparties to these agreements may breach or may be unable to perform their obligations. 
NRG may not be able to enter into replacement agreements on terms as favorable as its existing agreements, or at all. If the 
Company was unable to enter into replacement PPAs, the Company would sell its plants' power at market prices. If the Company 
is unable to enter into replacement fuel or fuel transportation purchase agreements, NRG would seek to purchase the Company's 
fuel requirements at market prices, exposing the Company to market price volatility and the risk that fuel and transportation may 
not be available during certain periods at any price.

The failure of any supplier or customer to fulfill its contractual obligations to NRG could have a material adverse effect on 
the Company's financial results. Consequently, the financial performance of the Company's facilities is dependent on the credit 
quality of, and continued performance by, suppliers and customers.

NRG relies on power transmission and distribution facilities that it does not own or control and that are subject to transmission 
constraints within a number of the Company's core regions. 

NRG depends on transmission and distribution facilities owned and operated by others to deliver wholesale power sales and 
retail  power  sales  to  its  customers.  If  transmission  or  distribution  is  disrupted,  including  by  force  majeure  events,  or  if  the 
transmission or distribution infrastructure is inadequate, NRG's ability to sell and deliver wholesale power may be adversely 
impacted. The Company also cannot predict whether transmission or distribution facilities will be expanded in specific markets 
to accommodate competitive access to those markets.

In addition, in certain of the markets in which NRG operates, energy transmission congestion may occur and the Company 
may be deemed responsible for congestion costs associated with wholesale power sales or purchases, or retail sales, particularly 
where the Company’s load is not co-located with its retail sales obligations. If NRG were liable for such congestion costs, the 
Company's financial results could be adversely affected.

Because NRG owns less than a majority of the ownership interests of some of its project investments, the Company cannot 
exercise complete control over their operations.

NRG has limited control over the operation of some project investments and joint ventures because the Company's investments 
are in projects where it beneficially owns less than a majority of the ownership interests. NRG seeks to exert a degree of influence 
with respect to the management and operation of projects in which it owns less than a majority of the ownership interests by 
negotiating to obtain positions on management committees or to receive certain limited governance rights, such as rights to veto 
significant actions. However, the Company may not always succeed in such negotiations. NRG may be dependent on its co-
venturers to operate such projects. The Company's co-venturers may not have the level of experience, technical expertise, human 
resources management and other attributes necessary to operate these projects optimally. The approval of co-venturers also may 
be required for NRG to receive distributions of funds from projects or to transfer the Company's interest in projects.

31

NRG may be unable to integrate the operations of acquired entities in the manner expected.

NRG  enters  into  acquisitions  that  result  in  various  benefits,  including,  among  other  things,  cost  savings  and  operating 
efficiencies. Achieving the anticipated benefits of these acquisitions depends on whether the businesses can be integrated into 
NRG in an efficient and effective manner. The integration process could take longer than anticipated and could result in the loss 
of  valuable  employees,  the  disruption  of  NRG's  businesses,  processes  and  systems  or  inconsistencies  in  standards,  controls, 
procedures, practices, policies and compensation arrangements, any of which could adversely affect the Company's ability to 
achieve the anticipated benefits of the acquisitions. NRG may have difficulty addressing possible differences in corporate cultures 
and management philosophies. Failure to achieve these anticipated benefits could result in increased costs or decreases in the 
amount of expected revenues and could adversely affect NRG's future business, financial condition, operating results and prospects.

Future acquisition or disposition activities could involve unknown risks and may have materially adverse effects and NRG may 
be subject to trailing liabilities from businesses that it disposes of or that are inactive.

NRG may in the future make acquisitions or dispositions of businesses or assets, acquire or sell books of retail customers, 
or pursue other business activities, directly or indirectly through subsidiaries, that involve a number of risks. The acquisition of 
companies and assets is subject to substantial risks, including the failure to identify material problems during due diligence, the 
risk of over-paying for assets or customers, the ability to retain customers and the inability to arrange financing for an acquisition 
as may be required or desired. Further, the integration and consolidation of acquisitions requires substantial human, financial and 
other resources and, ultimately, the Company's acquisitions may not be successfully integrated. In the case of dispositions, such 
risks may relate to employment matters, counterparties, regulators and other stakeholders in the disposed business, risks relating 
to separating the disposed assets from NRG’s business, risks related to the management of NRG’s ongoing business, risks unknown 
to NRG at the time, and other financial, legal and operational risks related to such disposition. In addition, NRG may be subject 
to material trailing liabilities from disposed businesses such as Clearway Energy Inc., and its Renewables Platform. Any such risk 
may result in one or more costly disputes or litigation.  There can be no assurances that any future acquisitions will perform as 
expected or that the returns from such acquisitions will support the indebtedness incurred to acquire them or the capital expenditures 
needed to develop them. There can also be no assurances that NRG will realize the anticipated benefits from any such dispositions. 
The failure to realize the anticipated returns or benefits from an acquisition or disposition could adversely affect NRG's results of 
operations, cash flows and financial condition.

NRG's business, financial condition and results of operations could be adversely impacted by strikes or work stoppages by its 
unionized employees or inability to replace employees as they retire.

As of December 31, 2018, approximately 26% of NRG's employees at its U.S. generation plants were covered by collective 
bargaining agreements. In the event that the Company's union employees strike, participate in a work stoppage or slowdown or 
engage in other forms of labor strife or disruption, NRG would be responsible for procuring replacement labor or the Company 
could experience reduced power generation or outages. Although NRG's ability to procure such labor is uncertain, contingency 
staffing planning is completed as part of each respective contract negotiations.  Strikes, work stoppages or the inability to negotiate 
future  collective  bargaining  agreements  on  favorable  terms  could  have  a  material  adverse  effect  on  the  Company's  business, 
financial condition, results of operations and cash flows. In addition, a number of the Company's employees at NRG's plants are 
close to retirement. The Company's inability to replace retiring workers could create potential knowledge and expertise gaps as 
such workers retire.

Changes in technology may impair the value of NRG's power plants and the attractiveness of its retail products.

Research and development activities are ongoing to provide alternative and more efficient technologies to produce power, 
including wind, photovoltaic (solar) cells, energy storage, and improvements in traditional technologies and equipment, such as 
more efficient gas turbines. Advances in these or other technologies could reduce the costs of power production to a level below 
what the Company has currently forecasted, which could adversely affect its cash flows, results of operations or competitive 
position. Technology, including distributed technology or changes in retail rate structures, may also have a material impact on the 
Company’s ability to retain retail customers.

The Company may potentially be affected by emerging technologies that may over time affect change in capacity markets and 
the energy industry overall with the inclusion of distributed generation and clean technology.  

Some emerging technologies like distributed renewable energy technologies, broad consumer adoption of electric vehicles 
and energy storage devices could affect the price of energy.  These emerging technologies may affect the financial viability of 
utility counterparties and could have significant impacts on wholesale market prices, which could ultimately have a material 
adverse effect on NRG's financial condition, results of operations and cash flows.

32

Risks that are beyond NRG's control, including but not limited to acts of terrorism or related acts of war, natural disaster, 
hostile cyber intrusions or other catastrophic events could  have a material adverse effect on NRG's financial condition, results 
of operations and cash flows. 

NRG's generation facilities and the facilities of third parties on which they rely may be targets of terrorist activities, as well 
as events occurring in response to or in connection with them, that could cause environmental repercussions and/or result in full 
or partial disruption of the facilities ability to generate, transmit, transport or distribute electricity or natural gas. Strategic targets, 
such as energy-related facilities, may be at greater risk of future terrorist activities than other domestic targets. Hostile cyber 
intrusions, including those targeting information systems as well as electronic control systems used at the generating plants and 
for  the  distribution  systems,  could  severely  disrupt  business  operations  and  result  in  loss  of  service  to  customers,  as  well  as 
significant expense to repair security breaches or system damage. Any such environmental repercussions or disruption could result 
in a significant decrease in revenues or significant reconstruction or remediation costs, beyond what could be recovered through 
insurance policies which could have a material adverse effect on the Company's financial condition, results of operations and cash 
flows. In addition, significant weather events or terrorist actions could damage or shut down the power transmission and distribution 
facilities upon which the Company's retail businesses are dependent. Power supply may be sold at a loss if these events cause a 
significant loss of retail customer load.

The operation of NRG’s businesses is subject to cyber-based security and integrity risk. 

Numerous  functions  affecting  the  efficient  operation  of  NRG’s  businesses  depend  on  the  secure  and  reliable  storage, 
processing and communication of electronic data and the use of sophisticated computer hardware and software systems. The 
operation  of  NRG’s  generation  plants,  including  STP,  and  of  NRG's  energy  and  fuel  trading  businesses  rely  on  cyber-based 
technologies and, therefore, subject to the risk that such systems could be the target of disruptive actions, particularly through 
cyber-attack  or  cyber  intrusion,  including  by  computer  hackers,  foreign  governments  and  cyber  terrorists,  or  otherwise  be 
compromised  by  unintentional  events. As  a  result,  operations  could  be  interrupted,  property  could  be  damaged  and  sensitive 
customer information could be lost or stolen, causing NRG to incur significant losses of revenues, other substantial liabilities and 
damages,  costs  to  replace  or  repair  damaged  equipment  and  damage  to  NRG's  reputation.  In  addition,  NRG  may  experience 
increased capital and operating costs to implement increased security for its cyber systems and plants. 

The Company's retail businesses are subject to the risk that sensitive customer data may be compromised, which could result 
in an adverse impact to its reputation and/or the results of operations of the Company's retail businesses.

The Company's retail businesses require access to sensitive customer data in the ordinary course of business.  Examples of 
sensitive customer data are names, addresses, account information, historical electricity usage, expected patterns of use, payment 
history, credit bureau data, credit and debit card account numbers, driver's license numbers, social security numbers and bank 
account information.  NRG's retail businesses may need to provide sensitive customer data to vendors and service providers, who 
require access to this information in order to provide services, such as call center operations, to NRG's retail businesses.  If a 
significant breach occurred, the reputation of NRG and its retail businesses may be adversely affected, customer confidence may 
be diminished, or NRG and its retail businesses may be subject to legal claims, any of which may contribute to the loss of customers 
and have a negative impact on the business and/or results of operations. 

Risks Related to Governmental Regulation and Laws

NRG's business is subject to substantial energy regulation and may be adversely affected by legislative or regulatory changes, 
as well as liability under, or any future inability to comply with, existing or future energy regulations or requirements.

NRG's business is subject to extensive U.S. federal, state and local laws and foreign laws. Compliance with the requirements 
under these legal and regulatory regimes may cause the Company to incur significant additional costs, reduce the Company's 
ability  to  sell  retail  power  within  certain  states  or  to  certain  classes  of  retail  customers;  or  restrict  the  Company’s  marketing 
practices, its ability to pass through costs to retail customers, or its ability to compete on favorable terms with competitors, including 
the incumbent utility.  Retail competition is regulated on a state-by-state level and is highly dependent on state laws, regulations 
and policies, which could change at any moment.  

Failure to comply with such requirements could result in the shutdown of a non-complying facility, the imposition of liens, 

fines, and/or civil or criminal liability.

33

Public utilities under the FPA are required to obtain FERC acceptance of their rate schedules for wholesale sales of electricity. 
Except for ERCOT generating facilities and power marketers, all of NRG's non-qualifying facility generating companies and 
power marketing affiliates in the U.S. make sales of electricity in interstate commerce and are public utilities for purposes of the 
FPA. FERC has granted each of NRG's generating and power marketing companies that make sales of electricity outside of ERCOT 
the authority to sell electricity at market-based rates. FERC's orders that grant NRG's generating and power marketing companies 
market-based rate authority reserve the right to revoke or revise that authority if FERC subsequently determines that NRG can 
exercise market power in transmission or generation, create barriers to entry, or engage in abusive affiliate transactions. In addition, 
NRG's market-based sales are subject to certain market behavior rules, and if any of NRG's generating and power marketing 
companies were deemed to have violated those rules, they are subject to potential disgorgement of profits associated with the 
violation and/or suspension or revocation of their market-based rate authority. If NRG's generating and power marketing companies 
were to lose their market-based rate authority, such companies would be required to obtain FERC's acceptance of a cost-of-service 
rate schedule and could become subject to the accounting, record-keeping, and reporting requirements that are imposed on utilities 
with cost-based rate schedules. This could have a material adverse effect on the rates NRG charges for power from its facilities.

Substantially all of the Company's generation assets are also subject to the reliability standards promulgated by the designated 
Electric Reliability Organization (currently NERC) and approved by FERC.  If NRG fails to comply with the mandatory reliability 
standards, NRG could be subject to sanctions, including substantial monetary penalties and increased compliance obligations. 
NRG is also affected by legislative and regulatory changes, as well as changes to market design, market rules, tariffs, cost allocations, 
and bidding rules that occur in the existing ISOs. The ISOs that oversee most of the wholesale power markets impose, and in the 
future may continue to impose, mitigation, including price limitations, offer caps, non-performance penalties and other mechanisms 
to address some of the volatility and the potential exercise of market power in these markets. These types of price limitations and 
other regulatory mechanisms may have a material adverse effect on the profitability of NRG's generation facilities that sell energy 
and capacity into the wholesale power markets.

The regulatory environment has undergone significant changes in the last several years due to state and federal policies 
affecting wholesale and retail competition and the creation of incentives for the addition of large amounts of new renewable 
generation and, in some cases, transmission.  These changes are ongoing, and the Company cannot predict the future design of 
the wholesale power markets or the ultimate effect that the changing regulatory environment will have on NRG's business. In 
addition, in some of these markets, interested parties have proposed material market design changes, including the elimination of 
a single clearing price mechanism, as well as proposals to reinstate the vertical monopoly utility of the markets or require divestiture 
by generating companies to reduce their market share.  If competitive restructuring of the electric power markets is reversed, 
discontinued, or delayed, the Company's business prospects and financial results could be negatively impacted.  In addition, since 
2010, there have been a number of reforms to the regulation of the derivatives markets, both in the United States and internationally.  
These regulations, and any further changes thereto, or adoption of additional regulations, including any regulations relating to 
position limits on futures and other derivatives or margin for derivatives, could negatively impact NRG’s ability to hedge its 
portfolio in an efficient, cost-effective manner by, among other things, potentially decreasing liquidity in the forward commodity 
and derivatives markets or limiting NRG’s ability to utilize non-cash collateral for derivatives transactions.

NRG’s business may be affected by state interference in the competitive wholesale marketplace.  

NRG’s generation and competitive retail businesses rely on a competitive wholesale marketplace.  The competitive wholesale 
marketplace may be impacted by out-of-market subsidies provided by states or state entities, including bailouts of uneconomic 
nuclear plants, imports of power from Canada, renewable mandates or subsidies, mandates to sell power below its cost of acquisition 
and associated costs, as well as out-of-market payments to new or existing generators.  These out-of-market subsidies to existing 
or new generation undermine the competitive wholesale marketplace, which can lead to premature retirement of existing facilities, 
including those owned by the Company.  If these measures continue, capacity and energy prices may be suppressed, and the 
Company may not be successful in its efforts to insulate the competitive market from this interference. The Company's retail 
businesses may be materially impacted by rules or regulations that allow regulated utilities to participate in competitive retail 
markets or own and operate facilities that could be provided by competitive market participants.

The integration of the Capacity Performance product into the PJM market and the Pay-for-Performance mechanism in ISO-
NE could lead to substantial changes in capacity income and non-performance penalties, which could have a material adverse 
effect on NRG’s results of operations, financial condition and cash flows.

Both ISO-NE and PJM operate a pay-for-performance model where capacity payments are modified based on real-time 
generator performance.  Capacity market prices are sensitive to design parameters, as well as additions of new capacity.  NRG 
may experience substantial changes in capacity income and non-performance penalties, which could have a material adverse effect 
on NRG’s results of operations, financial condition and cash flows.

34

NRG's  ownership  interest  in  a  nuclear  power  facility  subjects  the  Company  to  regulations,  costs  and  liabilities  uniquely 
associated with these types of facilities.

Under the Atomic Energy Act of 1954, as amended, or AEA, ownership and operation of STP, of which NRG indirectly owns 
a 44% interest, is subject to regulation by the NRC.  Such regulation includes licensing, inspection, enforcement, testing, evaluation 
and modification of all aspects of nuclear reactor power plant design and operation, environmental and safety performance, technical 
and financial qualifications, decommissioning funding assurance and transfer and foreign ownership restrictions.  The current 
facility operating licenses for STP expire on August 20, 2047 (Unit 1) and December 15, 2048 (Unit 2). 

There are unique risks to owning and operating a nuclear power facility.  These include liabilities related to the handling, 
treatment, storage, disposal, transport, release and use of radioactive materials, particularly with respect to spent nuclear fuel, and 
uncertainties  regarding  the  ultimate,  and  potential  exposure  to,  technical  and  financial  risks  associated  with  modifying  or 
decommissioning a nuclear facility.  The NRC could require the shutdown of the plant for safety reasons or refuse to permit restart 
of the unit after unplanned or planned outages.  New or amended NRC safety and regulatory requirements may give rise to additional 
operation and maintenance costs and capital expenditures.  Additionally, aging equipment may require more capital expenditures 
to keep each of these nuclear power plants operating efficiently.  This equipment is also likely to require periodic upgrading and 
improvement.  Any unexpected failure, including failure associated with breakdowns, forced outages, or any unanticipated capital 
expenditures, could result in reduced profitability.  STP will be obligated to continue storing spent nuclear fuel if the U.S. DOE 
continues to fail to meet its contractual obligations to STP made pursuant to the U.S. Nuclear Waste Policy Act of 1982 to accept 
and dispose of STP's spent nuclear fuel.  See also Item 1 — Regulatory Matters — Nuclear Operations - Decommissioning Trusts 
and  Item  1  —  Environmental  Matters — Federal  Environmental  Initiatives — Nuclear  Waste  for  further  discussion.    Costs 
associated with these risks could be substantial and could have a material adverse effect on NRG's results of operations, financial 
condition or cash flow to the extent not covered by the Decommissioning Trusts or recovered from ratepayers.  In addition, to the 
extent that all or a part of STP is required by the NRC to permanently or temporarily shut down or modify its operations, or is 
otherwise subject to a forced outage, NRG may incur additional costs to the extent it is obligated to provide power from more 
expensive alternative sources — either NRG's own plants, third party generators or the ERCOT — to cover the Company's then 
existing forward sale obligations.  Such shutdown or modification could also lead to substantial costs related to the storage and 
disposal of radioactive materials and spent nuclear fuel.

While STP maintains property and liability insurance for losses related to nuclear operations, there may be limitations on 
the amounts and types of insurance commercially available.  See also Item 15 — Note 21, Commitments and Contingencies, 
Nuclear Insurance.  An accident at STP or another nuclear facility could have a material adverse effect on NRG's financial condition, 
its operational results, or liquidity as losses may exceed the insurance coverage available and/or may result in the obligation to 
pay retrospective premium obligations.  

NRG is subject to environmental laws that impose extensive and increasingly stringent requirements on the Company's ongoing 
operations,  as  well  as  potentially  substantial  liabilities  arising  out  of  environmental  contamination.  These  environmental 
requirements and liabilities could adversely impact NRG's results of operations, financial condition and cash flows. 

NRG is subject to the environmental laws of foreign and U.S., federal, state and local authorities.  The Company must comply 
with numerous environmental laws and obtain numerous governmental permits and approvals to build and operate the Company's 
plants.  Federal and state environmental laws generally have become more stringent over time.  Should NRG fail to comply with 
any environmental requirements that apply to its operations, the Company could be subject to administrative, civil and/or criminal 
liability and fines, and regulatory agencies could take other actions seeking to curtail the Company's operations.  In addition, when 
new  requirements  take  effect  or  when  existing  environmental  requirements  are  revised,  reinterpreted  or  subject  to  changing 
enforcement policies, NRG's business, results of operations, financial condition and cash flows could be adversely affected.

NRG's businesses are subject to physical, market and economic risks relating to potential effects of climate change. 

Fluctuations  in  weather  and  other  environmental  conditions,  including  temperature  and  precipitation  levels,  may  affect 
consumer demand for electricity. In addition, the potential physical effects of climate change, such as increased frequency and 
severity of storms, floods and other climatic events, could disrupt NRG's operations and supply chain, and cause them to incur 
significant costs in preparing for or responding to these effects. These or other meteorological changes could lead to increased 
operating costs, capital expenses or power purchase costs. NRG's commercial and residential customers may also experience the 
potential physical impacts of climate change and may incur significant costs in preparing for or responding to these efforts, including 
increasing the mix and resiliency of their energy solutions and supply. 

35

Climate change could also affect the availability of a secure and economical supply of water in some locations, which is 
essential for the continued operation of NRG's generation plants. NRG monitors water risk carefully. If it is determined that a 
water supply risk exists that could impact projected generation levels at any plant risk mitigation efforts are identified and evaluated 
for implementation. 

GHG regulation could increase the cost of electricity generated by fossil fuels, and such increases could reduce demand for 
the power NRG generates and markets. Also, demand for NRG's energy-related services could be similarly impacted by consumers’ 
preferences or market factors favoring energy efficiency, low-carbon power sources or reduced electricity usage. 

Policies at the national, regional and state levels to regulate GHG emissions, as well as mitigate climate change, could adversely 
impact NRG's results of operations, financial condition and cash flows.

NRG's GHG emissions for 2018 can be found in Item 1, Business — Operational Statistics.  In 2015, the EPA promulgated 
the final GHG emissions rules for new and existing fossil-fuel-fired electric generating units, which have been stayed by the U.S. 
Supreme Court and the EPA has proposed repealing. 

The Company operates generating units in Connecticut, Delaware, Maryland, and New York which are subject to RGGI, 
which is a regional cap and trade system for CO2. In 2013, each of these states finalized a rule that reduced and will continue to 
reduce the number of allowances through 2020.  The nine RGGI states re-evaluated the program and published a model rule to 
further reduce the number of allowances. The revisions being currently contemplated could adversely impact NRG's results of 
operations, financial condition and cash flows. 

California has a CO2 cap and trade program for electric generating units greater than 25 MW. The impact on the Company 

depends on the cost of the allowances and the ability to pass these costs through to customers.  

Hazards customary to the power production industry include the potential for unusual weather conditions, which could affect 
fuel pricing and availability, the Company's route to market or access to customers, i.e., transmission and distribution lines, or 
critical plant assets. The contribution of climate change to the frequency or intensity of weather-related events could affect NRG's 
operations and planning process.

NRG's retail businesses are subject to changing state rules and regulations that could have a material impact on the profitability 
of its business lines.

The competitiveness of NRG's retail businesses partially depends on state regulatory policies that establish the structure, 
rules, terms and conditions on which services are offered to retail customers.  These state policies, which can include controls on 
the retail rates NRG's retail businesses can charge, the imposition of additional costs on sales, restrictions on the Company's ability 
to obtain new customers through various marketing channels and disclosure requirements, which can affect the competitiveness 
of NRG's retail businesses. The Company's retail businesses may be materially impacted by rules or regulations that allow regulated 
utilities to participate in competitive retail markets or own and operate facilities that could be provided by competitive market 
participants. Additionally, state or federal imposition of net metering or RPS programs can make it more or less expensive for 
retail customers to supplement or replace their reliance on grid power.  NRG's retail businesses have limited ability to influence 
development of these policies, and its business model may be more or less effective, depending on changes to the regulatory 
environment.   

The Company's international operations are exposed to political and economic risks, commercial instability and events beyond 
the Company's control in the countries in which it operates, which risks may negatively impact the Company's business.

The Company's international operations depend on products manufactured, purchased and sold in the U.S. and internationally, 
including in countries with political and economic instability.  In some cases, these countries have greater political and economic 
volatility and greater vulnerability to infrastructure and labor disruptions than in NRG's other markets.  Operating and seeking to 
expand business in a number of different regions and countries exposes the Company to a number of risks, including:

•  multiple and potentially conflicting laws, regulations and policies that are subject to change;

• 

• 

• 

• 

imposition of currency restrictions on repatriation of earnings or other restraints;

imposition of burdensome tariffs or quotas;

national and international conflict, including terrorist acts; and

political and economic instability or civil unrest that may severely disrupt economic activity in affected countries.

The occurrence of one or more of these events may negatively impact the Company's business, results of operations and 

financial condition.

36

Risks Related to Economic and Financial Market Conditions

NRG's level of indebtedness could adversely affect its ability to raise additional capital to fund its operations or return capital 
to stockholders. It could also expose it to the risk of increased interest rates and limit its ability to react to changes in the 
economy or its industry.

NRG's substantial debt could have negative consequences, including:

• 

• 

• 

• 

• 

• 

increasing NRG's vulnerability to general economic and industry conditions;

requiring a substantial portion of NRG's cash flow from operations to be dedicated to the payment of principal and interest 
on its indebtedness, therefore reducing NRG's ability to pay dividends to holders of its preferred or common stock or to 
use its cash flow to fund its operations, capital expenditures and future business opportunities;

limiting NRG's ability to enter into long-term power sales or fuel purchases which require credit support;

exposing NRG to the risk of increased interest rates because certain of its borrowings, including borrowings under its 
senior secured credit facility are at variable rates of interest;

limiting NRG's ability to obtain additional financing for working capital including collateral postings, capital expenditures, 
debt service requirements, acquisitions and general corporate or other purposes; and

limiting NRG's ability to adjust to changing market conditions and placing it at a competitive disadvantage compared to 
its competitors who have less debt.

The indentures for NRG's notes and senior secured credit facility contain financial and other restrictive covenants that may 
limit the Company's ability to return capital to stockholders or otherwise engage in activities that may be in its long-term best 
interests.  Furthermore, financial and other restrictive covenants contained in any project level subsidiary debt may limit the ability 
of NRG to receive distributions from such subsidiary. NRG's failure to comply with those covenants could result in an event of 
default which, if not cured or waived, could result in the acceleration of all of the Company's indebtedness.

In addition, NRG's ability to arrange financing, either at the corporate level, a non-recourse project-level subsidiary or 

otherwise, and the costs of such capital, are dependent on numerous factors, including:

• 

• 

• 

general economic and capital market conditions;

credit availability from banks and other financial institutions;

investor confidence in NRG, its partners and the regional wholesale power markets;

•  NRG's financial performance and the financial performance of its subsidiaries;

•  NRG's level of indebtedness and compliance with covenants in debt agreements;

•  maintenance of acceptable credit ratings;

• 

• 

cash flow; and

provisions of tax and securities laws that may impact raising capital.

NRG may not be successful in obtaining additional capital for these or other reasons. The failure to obtain additional capital 

from time to time may have a material adverse effect on its business and operations.

Adverse economic conditions could adversely affect NRG’s business, financial condition, results of operations and cash flows.

Adverse economic conditions and declines in wholesale energy prices, partially resulting from adverse economic conditions, 
may impact NRG’s earnings. The breadth and depth of negative economic conditions may have a wide-ranging impact on the U.S. 
business environment, including NRG’s businesses. In addition, adverse economic conditions also reduce the demand for energy 
commodities. Reduced demand from negative economic conditions continues to impact the key domestic wholesale energy markets 
NRG serves. The combination of lower demand for power and increased supply of natural gas has put downward price pressure 
on wholesale energy markets in general, further impacting NRG’s energy marketing results. In general, economic and commodity 
market conditions will continue to impact NRG’s unhedged future energy margins, liquidity, earnings growth and overall financial 
condition. In addition, adverse economic conditions, declines in wholesale energy prices, reduced demand for power and other 
factors may negatively impact the trading price of NRG’s common stock and impact forecasted cash flows, which may require 
NRG to evaluate its goodwill and other long-lived assets for impairment. Any such impairment could have a material impact on 
NRG’s financial statements. 

37

Goodwill and/or other intangible assets not subject to amortization that NRG has recorded in connection with its acquisitions 
are subject to mandatory annual impairment evaluations and as a result, the Company could be required to write off some or 
all of this goodwill and other intangible assets, which may adversely affect the Company's financial condition and results of 
operations.

In accordance with ASC 350, Intangibles — Goodwill and Other, or ASC 350, goodwill is not amortized but is reviewed 
annually or more frequently for impairment and other intangibles are also reviewed at least annually or more frequently, if certain 
conditions exist, and may be amortized. Any reduction in or impairment of the value of goodwill or other intangible assets will 
result in a charge against earnings which could materially adversely affect NRG's reported results of operations and financial 
position in future periods.

The Company has made investments, and may continue to make investments, in new business initiatives predominantly focused 
on consumer products and in markets that may not be successful, may not achieve the intended financial results or may result 
in product liability and reputational risk that could adversely affect the Company.

NRG continues to pursue growth in its existing businesses and markets and further diversification across the competitive 
energy value chain. NRG is continuing to pursue investment opportunities in renewables, consumer products and distributed 
generation.  Such initiatives may involve significant risks and uncertainties, including distraction of management from current 
operations, inadequate return on capital, and unidentified issues not discovered in the diligence performed prior to launching an 
initiative or entering a market.  

As part of these initiatives, the Company may be liable to customers for any damage caused to customers’ homes, facilities, 
belongings or property during the installation of Company products and systems, such as residential solar systems and mass market 
back-up generators. In addition, shortages of skilled labor for Company projects could significantly delay a project or otherwise 
increase its costs.  The products that the Company sells or manufactures may expose the Company to product liability claims 
relating to personal injury, death, or environmental or property damage, and may require product recalls or other actions. Although 
the Company maintains liability insurance, the Company cannot be certain that its coverage will be adequate for liabilities actually 
incurred or that insurance will continue to be available to the Company on economically reasonable terms, or at all.  Further, any 
product liability claim or damage caused by the Company could significantly impair the Company’s brand and reputation, which 
may result in a failure to maintain customers and achieve the Company’s desired growth initiatives in these new businesses.

Energy revenue consists of revenues received from third parties as well as from the Company's retail businesses, for sales 
of electricity in the day-ahead and real-time markets, as well as bilateral sales.  It also includes energy sold through long-term 
PPAs for renewable facilities.  In addition, energy revenue includes revenues from the settlement of financial instruments and net 
realized trading revenues.

Capacity revenue consists of revenues received from a third party at either the market or negotiated contract rates for making 
installed generation capacity available in order to satisfy system integrity and reliability requirements.  Capacity revenue also 
includes revenues from the settlement of financial instruments.  In addition, capacity revenue includes revenues received under 
tolling arrangements, which entitle third parties to dispatch NRG's facilities and assume title to the electrical generation produced 
from that facility.

Retail  revenue,  representing  operating  revenues  of  NRG's  retail  businesses,  consists  of  revenues  from  retail  sales  to 
residential, small business, commercial, industrial and governmental/institutional customers, revenues from the sale of excess 
supply into various markets, primarily in Texas, as well as product sales.

Mark-to-market for economic hedging activities includes asset-backed hedges that have not been designated as cash flow 

hedges and ineffectiveness on cash flow hedges.

Contract amortization revenue consists of the amortization of the intangible assets for net in-market C&I contracts established 
in connection with the acquisitions of Reliant Energy and Green Mountain Energy.  These amounts are amortized into revenue 
over the term of the underlying contracts based on contracted volumes. 

Other revenues consists of operations and maintenance fees, or O&M fees, construction management services, or CMA fees, 
sale of natural gas and emission allowances, and revenues from ancillary services. O&M fees consist of revenues received from 
providing certain third party and unconsolidated affiliates with services under long-term operating agreements.  CMA fees are 
earned  where  NRG  provides  certain  management  and  oversight  of  construction  projects  pursuant  to  negotiated  agreements.  
Ancillary services are comprised of the sale of energy-related products associated with the generation of electrical energy such as 
spinning reserves, reactive power and other similar products.  Other revenues also include unrealized trading activities.

Executive Summary

NRG is an energy company built on dynamic retail brands with diverse generation assets. NRG brings the power of energy 
to consumers by producing, selling and delivering electricity and related products and services in major competitive power markets 
in the U.S. in a manner that delivers value to all of NRG's stakeholders. The Company sells energy, services, and innovative, 
sustainable products and services directly to retail customers under the names "NRG" and "Reliant" and other brand names owned 
by NRG supported by approximately 23,000(a) MW of generation as of December 31, 2018.

Business Environment

The industry dynamics and external influences affecting the Company and its businesses, and the power generation and 

retail energy industry in general in 2018 and for the future medium term include:

Commodities Markets — The price of natural gas plays an important role in setting the price of electricity in many of the 
regions where NRG operates. Natural gas prices are driven by variables including demand from the industrial, residential, and 
electric sectors, productivity across natural gas supply basins, costs of natural gas production, changes in pipeline infrastructure, 
and the financial and hedging profile of natural gas consumers and producers.  In 2018, average natural gas prices at Henry Hub 
was 1.0% lower than in 2017.

If long-term gas prices decrease, the Company is likely to encounter lower realized energy prices, leading to lower energy 
revenues as higher priced hedge contracts mature and are replaced by contracts with lower gas and power prices.  NRG's retail 
gross margins have historically improved as natural gas prices decline and are likely to partially offset the impact of declining gas 
prices on conventional wholesale power generation.  To further mitigate this impact, NRG may increase its percentage of coal and 
nuclear  capacity  sold  forward  using  a  variety  of  hedging  instruments,  as  described  under  the  heading  "Energy-Related 
Commodities" in Item 15 — Note 5, Accounting for Derivative Instruments and Hedging Activities, to the Consolidated Financial 
Statements.

Natural gas prices are a primary driver of coal demand.  The low-priced commodity environment has stressed coal equities, 
leading coal suppliers to file for bankruptcy protection, launch debt exchanges, rationalize assets, and cut production.  If multiple 
parties withdraw from the market, liquidity could be challenged in the short term.  Inventory overhang will be utilized to offset 
production losses.  Coal prices are typically affected by the price of natural gas.  

(a) excluding discontinued operations and held for sale

 Electricity Prices — The price of electricity is a key determinant of the profitability of the Company.  Many variables such 
as the price of different fuels, weather, load growth and unit availability all coalesce to impact the final price for electricity and 
the Company's profitability. An increase in supply cost volatility in the competitive retail markets may result in smaller companies 
choosing to exit the market, which may result in further consolidation in the competitive retail space. The following table summarizes 
average on-peak power prices for each of the major markets in which NRG operates for the years ended December 31, 2018, 2017, 
and 2016. Power prices were higher for the year ended December 31, 2018 as compared to the same period in 2017 and 2016.  
ERCOT power prices were higher primarily due to the continued effect of lower reserve margins as a result of asset retirements 
in the region.  Power prices in East region increased for the year ended December 31, 2018 as compared to the same period in 
2017 and 2016 primarily driven by higher winter demand and higher natural gas prices in the fourth quarter of 2018.

The average realized power prices for December 31, 2018 as compared to the same period in 2017, increased in Texas as 

a result of higher power prices, and decreased in East/West as a result of the roll off of hedges. The average realized power 
prices for December 31, 2017 as compared to the same period in 2016 decreased in both Texas and East/West as a result of the 
roll off of hedges.

Clean Infrastructure Development — Policy mechanisms at the state and federal level including production and investment 
tax credits, cash grants, loan guarantees, accelerated depreciation tax benefits, RPS, and carbon trading plans, have supported and 
continue  to  support  the  development  of  renewable  generation,  demand-side  and  smart  grid,  and  other  clean  infrastructure 
technologies. In addition, the costs associated with the development of clean infrastructure, such as wind and solar generating 
facilities, continues to decline. These factors continue to drive increases in the development of clean infrastructure in the markets 
where the Company participates, which may impact the ability of the Company's generating facilities to participate in those markets. 
According to ERCOT, Inc., more than 30% of 2018 energy consumption in the ERCOT market was generated from carbon-free 
resources with wind power contributing 19%. Certainly, subsidies and incentives have contributed to the increase in renewable 
power sources, but it is also true that customer awareness/preferences have shifted toward sustainable solutions. Alternatively, 
increased  demand  for  sustainable  energy  products  from  both  residential  and  commercial  consumers  creates  opportunities  for 
diversified product offerings in competitive retail markets. 

49

 
 
Digitization and Customization — The electric industry is experiencing major technology changes in the way power is 
distributed and used by end-use customers. The electric grid is shifting from a centralized analog system, where power is generated 
from limited sources and flows in one direction, to a decentralized multidirectional system, where power can be generated from 
a number of distributed resources and stored or dispatched on an as-needed basis. In addition, consumers are seeking new ways 
to engage with their power providers. Technologies like smart thermostats, appliances and electric vehicles are giving individuals 
more choice and control over their electricity usage. 

Weather — Weather conditions in the regions of the U.S. in which NRG does business influence the Company's financial 
results.  Weather conditions can affect the supply and demand for electricity and fuels and may also impact the availability of the 
Company's generating assets.  Changes in energy supply and demand may impact the price of these energy commodities in both 
the spot and forward markets, which may affect the Company's results in any given period. Typically, demand for and the price 
of electricity is higher in the summer and the winter seasons, when temperatures are more extreme. The demand for and price of 
natural gas is also generally higher in the winter.  However, all regions of the U.S. typically do not experience extreme weather 
conditions at the same time, thus NRG is typically not exposed to the effects of extreme weather in all parts of its business at once.

Other Factors — A number of other factors significantly influence the level and volatility of prices for energy commodities 

and related derivative products for NRG's business.  These factors include:

• 

• 
• 

• 

• 

• 

• 

seasonal, daily and hourly changes in demand;

extreme peak demands;
available supply resources;

transportation and transmission availability and reliability within and between regions;

location of NRG's generating facilities relative to the location of its load-serving opportunities;

procedures used to maintain the integrity of the physical electricity system during extreme conditions; and

changes in the nature and extent of federal and state regulations

These factors can affect energy commodity and derivative prices in different ways and to different degrees.  These effects 

may vary throughout the country as a result of regional differences in:

•  weather conditions;

•  market liquidity;

• 

• 

• 

capability and reliability of the physical electricity and gas systems;

local transportation systems; and

the nature and extent of electricity deregulation

Transformation Plan

NRG is well underway in executing its Transformation Plan. The Company expects to fully implement the Transformation 
Plan by the end of 2020 with a significant portion completed in 2018. The three-part, three-year plan is comprised of the following 
targets and the Company's achievements towards such targets are as follows:

Operations and Cost Excellence

Recurring cost savings and margin enhancement of $1,065 million, which consists of $590 million of cumulative cost savings, 
a $215 million net margin enhancement program, $50 million annual reduction in maintenance capital expenditures, and $210 
million in permanent selling, general and administrative expense reduction associated with asset sales. The Company realized 
annual cost savings of $532 million and $32 million of margin enhancements during the year ended December 31, 2018 and is on 
track to realize $590 million of cost savings and $135 million of margin enhancements in 2019.

The Company expects to realize (i) $370 million of non-recurring working capital improvements through 2020 and (ii) 
approximately $290 million one-time costs to achieve. By December 31, 2018, NRG has realized $333 million of non-recurring 
working capital improvements and $194 million of one-time costs to achieve. The Company expects to incur approximately $95 
million of one-time costs to achieve in 2019.

Portfolio Optimization

Targeted and completed $3.0 billion of asset sale cash proceeds received through February 28, 2019, as described below:

•   In 2017, NRG executed asset sales of 322 MW for aggregate cash of $150 million, which includes sales to NRG Yield, Inc. 

and the sale of Minnesota wind projects to third parties

•  On March 30, 2018, the Company completed the sale of 100% of its ownership interest in Buckthorn Solar to NRG Yield, 

Inc. for cash consideration of approximately $42 million 

•  On August 1, 2018, the Company completed the sale of 100% of its ownership interests in BETM to Diamond Energy 
Trading and Marketing, LLC for $70 million, excluding working capital adjustments.  The sale also resulted in the release 
and return of approximately $119 million of letters of credit, $32 million of parent guarantees, and $4 million of net cash 
collateral to NRG

•  On August 31, 2018, the Company completed the sale of its interest in NRG Yield, Inc. and its Renewables Platform to GIP, 

for approximately $1.348 billion in cash proceeds

•  On November 1, 2018, the Company offered to Clearway Energy, Inc. its ownership interest in Agua Caliente Borrower 1, 
LLC, for approximately $120 million, which owns a 35% interest in AGua Caliente, a 290 MW utility scale solar project.  
The offer expired on January 31, 2019 with no action taken by Clearway Energy, Inc. As a result of this expiration, the 
Company has removed this asset from the target asset sale cash proceeds under the Transformation Plan.

•   During  the  twelve  months  ended  December  31,  2018,  the  Company  completed  the  sale  of  various  other  assets  for     

approximately $28 million

•  On February 4, 2019, NRG sold the South Central portfolio, a 3,555 MW portfolio of generation assets, for cash consideration 

of $1 billion, excluding working capital and other adjustments

•  On February 20, 2019, NRG completed the sale of Guam for cash consideration of approximately $8 million 
•  On February 27, 2019, NRG sold the Carlsbad project, a 528 MW natural gas-fired power plant, for cash consideration of 

$387 million, excluding working capital and other adjustments 

Capital Structure and Allocation 

As of December 31, 2018, the Company achieved the previously announced target of reducing consolidated corporate debt 
to 3.0x net debt / adjusted EBITDA(a) credit ratio on a pro forma basis that includes the South Central Portfolio sale proceeds. To 
achieve this ratio, the Company completed the following:

•  Reduction of $9.2 billion in non-recourse debt related to the sale of NRG Yield, Inc. and the Renewable Platform, which 
includes the debt for Carlsbad Energy Center, as well as the impact of deconsolidation of Agua Caliente and Ivanpah
•  The Company has completed its targeted $640 million of debt reduction through the redemption of $485 million of its 
outstanding 6.250% senior notes due 2022 and the Term Loan prepayment of $155 million. The annualized interest 
savings related to these activities to date totals $37 million

In 2018, the Company's board of directors authorized the Company to repurchase $1.5 billion of its common stock. As of 
February 28, 2019, the Company completed $1.5 billion of repurchases at an average price of $36.24 per share. In addition, the 
Company's board of directors authorized in February 2019 an additional $1 billion share repurchase program to be executed in 
2019.

 Economic Gross Margin

In addition to gross margin, the Company evaluates its operating performance using the measure of economic gross margin, 
which is not a GAAP measure and may not be comparable to other companies’ presentations or deemed more useful than the 
GAAP information provided elsewhere in this report.  Economic gross margin should be viewed as a supplement to and not a 
substitute for the Company's presentation of gross margin, which is the most directly comparable GAAP measure.  Economic 
gross margin is not intended to represent gross margin.  The Company believes that economic gross margin is useful to investors 
as it is a key operational measure reviewed by the Company's chief operating decision maker.  Economic gross margin is defined 
as the sum of energy revenue, capacity revenue and other revenue, less cost of fuels and other cost of sales.

Economic  gross  margin  does  not  include  mark-to-market  gains  or  losses  on  economic  hedging  activities,  contract 

amortization, emission credit amortization, or other operating costs.

The tables below present the composition and reconciliation of gross margin and economic gross margin which reflects the 

Company's current view of reporting segments for the years ended December 31, 2018 and 2017:

Includes intercompany purchases of $1,163 million and $1,090 million in 2018 and 2017, respectively

Retail gross margin increased $277 million and retail economic gross margin increased $200 million for the year ended 

December 31, 2018, compared to the same period in 2017, due to:

Higher gross margin driven by margin enhancement initiatives enhancing customer product, retention, term
and mix of $3.30 per MWh, or $208 million partially offset by higher supply costs due to increased power
prices in ERCOT of $2.40 MWh, or $150 million.

 Higher gross margin due to higher volumes from net higher average customer counts primarily driven by

XOOM acquisition in June 2018

Higher gross margin from the favorable impact of weather due to $44 million from an increase in load in 2018
of 1,893,000 MWh partially offset by an unfavorable impact of $14 million from selling back additional
excess supply in 2018 as well as $16 million due to the impacts of Hurricane Harvey in 2017

Higher gross margin due to an increase in capacity revenues from the business solutions unit mainly due to

approximately 1,600 additional MWs sold and margin enhancements from the sale of additional capacity of
$11 million

which include intercompany sales, during the year ended December 31, 2018, compared to the same period in 2017.

The tables below describe the change in Generation gross margin and generation economic gross margin:

Texas Region

Higher gross margin due to a 11% increase in average realized prices

Higher gross margin from sales of NOx emission credits

Higher gross margin from commercial optimization activities

Higher gross margin due to margin enhancement initiatives from reduced fuel supply costs

Lower gross margin driven by planned outages for both units at STP in 2018 as compared to a single unit
planned outage in 2017

Lower gross margin due to an increase in tolling purchases in 2018 as a result of increased demand and the

cancellation of the Greens Bayou RMR agreement in 2017

Other
Increase in economic gross margin

Decrease in mark-to-market for economic hedging primarily due to net unrealized gains/losses on open

positions related to economic hedges

Increase in contract and emission credit amortization
Decrease in gross margin

East/West Region 

Lower gross margin primarily due to Ivanpah and Agua Caliente being deconsolidated in April 2018 and

August 2018, respectively

Lower gross margin driven by a 26% decrease in realized capacity pricing in New York and expiration of the

Long Beach capacity toll in July 2017

Lower gross margin mainly due to an 11% decrease in average realized prices, primarily at Midwest Generation

Lower gross margin due to decreased load contract volumes coupled with lower prices

Lower gross margin at Sunrise in 2018 due to planned major maintenance activities that extended into a forced

outage.

Higher gross margin due to a 32% increase in PJM capacity prices and a 51% increase in NEISO capacity

prices

Higher gross margin from commercial optimization activities

Higher gross margin due to 2017 lower cost of market adjustment for fuel inventory

Higher gross margin as a result of trading activity at BETM

The reversals of acquired gain or loss positions were valued based upon the forward prices on the acquisition date.

For the year ended December 31, 2018 the $130 million loss in operating revenues from economic hedge positions was 
driven primarily by the reversal of previously recognized unrealized gains on contracts that settled during the period, as well as 
a decrease in value of open positions as a result of losses on ERCOT heat rate positions due to heat rate expansion.  The $144 
million gain in operating costs and expenses from economic hedge positions was driven primarily by an increase in the value of 
open positions as a result of increases in ERCOT heat rate, partially offset by the reversal of acquired gain positions.  

In accordance with ASC 815, the following table represents the results of the Company's financial and physical trading of 
energy commodities for the years ended December 31, 2018 and 2017.  The realized and unrealized financial and physical trading 
results  are  included  in  operating  revenue. The  Company's  trading  activities  are  subject  to  limits  within  the  Company's  Risk 
Management Policy.

For the year ended December 31, 2018, NRG's overall effective tax rate was different than the federal statutory tax rate of 
21% primarily due to a tax benefit for the change in valuation allowance, the generation of PTCs from various wind facilities, and 
establishment of the previously sequestered ATM credit receivable, partially offset by current state tax expense.

Gross Margin

The Company calculates gross margin in order to evaluate operating performance as operating revenues less cost of sales, 
which includes cost of fuel, other costs of sales, contract and emission credit amortization and mark-to-market for economic 
hedging activities. 

Economic Gross Margin

In addition to gross margin, the Company evaluates its operating performance using the measure of economic gross margin, 
which is not a GAAP measure and may not be comparable to other companies’ presentations or deemed more useful than the 
GAAP information provided elsewhere in this report.  Economic gross margin should be viewed as a supplement to and not a 
substitute for the Company's presentation of gross margin, which is the most directly comparable GAAP measure.  Economic 
gross margin is not intended to represent gross margin.  The Company believes that economic gross margin is useful to investors 
as it is a key operational measure reviewed by the Company's chief operating decision maker.  Economic gross margin is defined 
as the sum of energy revenue, capacity revenue and other revenue, less cost of fuels and other cost of sales.

Economic  gross  margin  does  not  include  mark-to-market  gains  or  losses  on  economic  hedging  activities,  contract 

amortization, emission credit amortization, or other operating costs.

The tables below present the composition and reconciliation of gross margin and economic gross margin which reflects the 

Company's current view of reporting segments for the years ended December 31, 2017 and 2016:

Retail gross margin decreased $227 million and retail economic gross margin decreased $47 million for the year ended 

December 31, 2017, compared to the same period in 2016, due to: 

Lower gross margin due to lower rates to customers driven by customer product, term and mix of $103 million

or approximately $1.60 per MWh, partially offset by lower supply cost of $28 million or approximately
$0.50 per MWh driven by a decrease in supply costs

$

(75)

(In millions)

Lower gross margin related to the impact of Hurricane Harvey in 2017, driven by a reduction in load of

200,000 MWh resulting in an impact of $9 million and the unfavorable impact of selling back excess supply
along with $7 million of customer relief

Lower gross margin due to milder weather conditions in 2017 as compared to 2016 resulting in a reduction in

load of 350,000 MWh

Higher gross margin driven by higher average customer counts of 85,000 along with higher average usage due

to customer mix

The tables below describe the change in generation gross margin and generation economic gross margin:

Texas Region

Lower gross margin due to a 14% decrease in average realized prices due to lower hedged power prices

Lower gross margin due to lower gas generation driven by the current mothball status of Gregory in Texas

Higher gross margin due to a 17% increase in coal generation driven by the timing of planned and unplanned

outages

Higher gross margin due to a decrease in tolling prices in 2017 offset by the cancellation of the Greens Bayou

RMR agreement in 2017

Lower gross margin due to a decrease in generation driven by lower economic generation due to milder
weather conditions and the Will County outage partially offset by increased generation at Cottonwood

Lower gross margin due to a lower cost of market adjustment for fuel oil inventory

Lower gross margin due to lower load contracted prices coupled with slightly lower volumes

Lower gross margin by BETM due to higher gains in 2016 on over the counter strategies, offset in small part by

higher gains in 2017 congestion strategies

Lower gross margin due to lower capacity bi-lateral margins in 2017

Lower gross margins due to the sale of certain renewable assets in 2017

Lower gross margin at Agua driven by lower sales volumes resulting from weather and outages in 2017

Lower gross margins due to higher business interruption proceeds from Cottonwood in 2016 offset by Ivanpah

The reversals of acquired gain or loss positions were valued based upon the forward prices on the acquisition date.

For the year ended December 31, 2017, the $252 million gain in operating revenues from economic hedge positions was 
driven primarily by the reversal of previously recognized unrealized losses on contracts that settled during the period, as well as 
an increase in value of open positions as a result of decreases in gas prices. The $46 million loss in operating costs and expenses 
from economic hedge positions was driven primarily by the reversal of previously recognized unrealized gains on contracts that 
settled during the period, partially offset by an increase in the value of open positions as a result of increases in ERCOT heat rate.  

In accordance with ASC 815, the following table represents the results of the Company's financial and physical trading of 
energy commodities for the years ended December 31, 2017 and 2016. The realized and unrealized financial and physical trading 
results  are  included  in  operating  revenues. The  Company's  trading  activities  are  subject  to  limits  within  the  Company's  Risk 
Management Policy.

Selling, general and administrative expenses decreased by $196 million(a) for the year ended December 31, 2017 

compared to the same period in 2016, primarily due to a reduction in personnel costs and selling and marketing activities as the 
Company continues to focus on cost management.

      (a) Approximately $98 million of additional cost savings were achieved in the year ended December 31, 2017, as compared to the year ended December 31,             

2016, as the savings became permanent through the Transformation Plan

Development Costs

Development costs decreased by $26 million for the year ended December 31, 2017, compared to the same period in 2016, 
due to the strategic decision for a more focused development program primarily related to Renewables and the sale of EVgo in 
2016.

Gain/(Loss) on Sale of Assets

Gain on sale of assets for the year ended December 31, 2017, represents a gain on the sale of  land.  The  loss on sale of 
assets for the year ended December 31, 2016 is  primarily due to the loss on sale of the Company's majority interest in its EVgo 
business to Vision Ridge Partners, which resulted in a loss on sale as described in Item 15 — Note 3,  Acquisitions, Discontinued 
Operations and Dispositions, to the Consolidated Financial Statements. 

Impairment Losses on Investments

For the year ended December 31, 2017, the Company recorded impairment losses of $79 million, which is primarily due to 
impairments on the Company's interests in Petra Nova Parish Holdings as well as  as impairments on other investments as further 
described in Item 15 — Note 9, Asset Impairments, to the Consolidated Financial Statements.

For the year ended December 31, 2016, the Company recorded impairment losses on certain of its cost and equity method 
investments of $270 million, as further described in Item 15 — Note 9, Asset Impairments, to the Consolidated Financial Statements.

72

Loss on Debt Extinguishment

A loss on debt extinguishment of $49 million was recorded for the year ended December 31, 2017, primarily driven by the 
repurchase of Senior Notes at a price above par value and the write-off of the unamortized debt issuance costs related to the 
replacement of the 2018 Term Loan Facility with the new 2023 Term Loan Facility.

A loss on debt extinguishment of $142 million was recorded for the year ended December 31, 2016, primarily driven by the 
repurchase of NRG senior notes at a price above par value and the write-off of the unamortized debt issuance costs related to the 
replacement of the 2018 Term Loan Facility with the new 2023 Term Loan Facility.

Interest Expense

NRG's interest expense decreased by $26 million for the year ended December 31, 2017, compared to the same period 

in 2016, primarily due to lower debt balances resulting in less interest.

Income Tax Expense

For the year ended December 31, 2017, NRG recorded an income tax benefit of $44 million on a pre-tax loss of $1,389 
million.  For the same period in 2016, NRG recorded an income tax expense of $25 million on pre-tax loss of $931 million.  The 
effective tax rate was 3.2% and (2.7)% for the years ended December 31, 2017 and 2016, respectively.

For the year ended December 31, 2017, NRG's overall effective tax rate was different than the federal statutory tax rate of 
35% primarily due to tax expense recorded from the revaluation of the existing net deferred tax asset and state taxes, partially 
offset by the change in valuation allowance, establishing the AMT credit receivable and the generation of PTCs from various wind 
facilities. The tax expense recorded for revaluation of the net deferred tax asset is required to reflect the reduction in the corporate 
income tax rate from 35% to 21% in accordance with the Tax Act.

mix of earnings and losses and changes in valuation allowances in accordance with ASC 740. These factors and others, including 
the Company's history of pre-tax earnings and losses, are taken into account in assessing the ability to realize deferred tax assets.

Discussion.  Cash and cash equivalents at December 31, 2018 were predominantly held in money market funds invested in treasury 
securities, treasury repurchase agreements or government agency debt.  

Management believes that the Company's liquidity position and cash flows from operations will be adequate to finance 
operating and maintenance capital expenditures, to fund dividends to NRG's common stockholders, and to fund other liquidity 
commitments.  Management continues to regularly monitor the Company's ability to finance the needs of its operating, financing 
and investing activity within the dictates of prudent balance sheet management.

On December 6, 2018, Moody's upgraded the NRG corporate family rating to Ba2 and senior unsecured rating to Ba3 with 

positive outlook. The rating agency also affirmed the company's senior secured rating at Baa3.

On September 10, 2018, S&P upgraded its issuer credit rating to BB with a stable outlook. At the same time they raised the 

issue-level secured and unsecured ratings to BBB and BB respectively.

Sources of Liquidity

The principal sources of liquidity for NRG's operating and capital expenditures are expected to be derived from cash on 
hand,  cash  flows  from  operations,  cash  proceeds  from  future  sales  of  assets  and  financing  arrangements. As  described  in 
Item 15 — Note 11, Debt and Capital Leases, to the Consolidated Financial Statements, the Company's financing arrangements 
consist mainly of the Senior Credit Facility, the Senior Notes, and project-related financings.

First Lien Structure

NRG has granted first liens to certain counterparties on a substantial portion of the Company's assets, excluding assets 
acquired in the EME (including Midwest Generation) acquisitions  and NRG's assets that have project-level financing.  NRG uses 
the first lien structure to reduce the amount of cash collateral and letters of credit that it would otherwise be required to post from 
time to time to support its obligations under out-of-the-money hedge agreements for forward sales of power or gas used as a proxy 
for power.  To the extent that the underlying hedge positions for a counterparty are out-of-the-money to NRG, the counterparty 
would have claim under the first lien program.  The first lien program limits the volume that can be hedged, not the value of 
underlying out-of-the-money positions.  The first lien program does not require NRG to post collateral above any threshold amount 
of exposure.  Within the first lien structure, the Company can hedge up to 80% of its coal and nuclear capacity and 10% of its 
other assets with these counterparties for the first 60 months and then declining thereafter.  Net exposure to a counterparty on all 
trades must be positively correlated to the price of the relevant commodity for the first lien to be available to that counterparty.  
The first lien structure is not subject to unwind or termination upon a ratings downgrade of a counterparty and has no stated 
maturity date.

The Company's first lien counterparties may have a claim on its assets to the extent market prices exceed the hedged prices.  

As of December 31, 2018, all hedges under the first liens were out-of-the-money on a counterparty aggregate basis.

Uses of Liquidity

The Company's requirements for liquidity and capital resources, other than for operating its facilities, can generally be categorized 
by the following: (i) commercial operations activities; (ii) debt service obligations, as described more fully in Item 15 — Note 11, Debt 
and  Capital  Leases,  to  the  Consolidated  Financial  Statements;  (iii) capital  expenditures,  including  repowering  development,  and 
environmental;  and  (iv) allocations  in  connection  with  acquisition  opportunities,  debt  repayments,  return  of  capital  and  dividend 
payments to stockholders, as described in Item 15 — Note 14, Capital Structure, to the Consolidated Financial Statements.

Commercial Operations 

The Company's commercial operations activities require a significant amount of liquidity and capital resources. These liquidity 
requirements  are  primarily  driven  by:  (i) margin  and  collateral  posted  with  counterparties;  (ii)  margin  and  collateral  required  to 
participate in physical markets and commodity exchanges; (iii) timing of disbursements and receipts (e.g. buying fuel before receiving 
energy revenues); (iv) initial collateral for large structured transactions; and (v) collateral for project development.  As of December 31, 
2018, commercial operations had total cash collateral outstanding of $287 million and $793 million outstanding in letters of credit to 
third parties primarily to support its commercial activities for both wholesale and retail transactions.   As of December 31, 2018, total 
collateral held from counterparties was $33 million in cash and $108 million of letters of credit.  

 Future liquidity requirements may change based on the Company's hedging activities and structures, power purchases and sales, 
fuel purchases, and future market conditions, including forward prices for energy and fuel and market volatility. In addition, liquidity 
requirements are dependent on the Company's credit ratings and general perception of its creditworthiness.

2023 Term Loan Facility 

In accordance with the terms of the Credit Agreement, on October 5, 2018, the Company initiated an asset sale offer to purchase 
a portion of its Term Loan following the sale of NRG Yield and the Renewables Platform. The offer expired on November 5, 2018, 
and $260 million of Term Loan holders accepted the offer. As a result, the Company prepaid $155 million of Term Loans as part of its 
de-leveraging plan, as well as established an incremental first lien secured loan term facility under the Senior Credit Facility in the 
aggregate principal amount of $105 million on the same terms and conditions to stay within its debt reduction target. 

In accordance with the terms of the credit agreement, upon the consummation of the sales of the South Central Portfolio and 
Carlsbad, the Company will initiate asset sale offers to purchase a portion of its Term Loan. The Company has one year from the date 
of each sale to initiate the offer.

Senior Note Repurchases in 2018

During the year ended  December 31, 2018, the Company redeemed $1.1 billion in aggregate principal of its Senior Notes for 
$1.1  billion,  which  included  accrued  interest  of  $14  million.    In  connection  with  the  redemptions,  a  $38  million  loss  on  debt 
extinguishment was recorded in 2018, which included the write-off of previously deferred financing costs of $7 million.

Environmental Capital Expenditures Estimate

NRG estimates that environmental capital expenditures from 2019 through 2023 required to comply with environmental 
laws will be approximately $35 million. These costs are primarily associated with the cost of adding NOx controls in Connecticut.

The table below summarizes the status of NRG's coal fleet with respect to air quality controls.  Planned investments are 
either in construction or budgeted in the existing capital expenditures budget.  Changes to regulations could result in changes to 
planned installation dates.  NRG uses an integrated approach to fuels, controls and emissions markets to meet environmental 
standards.

The Company returned $37 million of capital to shareholders in the year ended 2018 through a $0.12 dividend per common 

share. 

On January 23, 2019, NRG declared a quarterly dividend on the Company's common stock of $0.03 per share, or $0.12 per 
share on an annualized basis, payable on February 15, 2019, to stockholders of record as of February 1, 2019.  The Company's 
common stock dividends are subject to available capital, market conditions, and compliance with associated laws and regulations. 

80

 
Share Repurchases

In 2018, the Company's board of directors authorized the Company to repurchase $1.5 billion of its common stock. 
During the year ended December 31, 2018, the Company repurchased a total of 35,234,664 shares under these programs for 
$1.25 billion, and the remaining $250 million was repurchased by February 28, 2019. The average price paid per share for the 
$1.5 billion share repurchase was $36.24. In addition, the Company's board of directors authorized in February 2019 an 
additional $1 billion share repurchase program to be executed in 2019. See Note 14, Capital Structure, for additional 
discussion. 

Targeted Debt Reduction

NRG is revising its balance sheet target ratios in order to further strengthen its balance sheet. In order to achieve the revised 
balance sheet targets, the Company is reserving up to $600 million in 2019 capital which may be allocated toward debt reduction. 

Small Book Acquisitions

During 2018, the Company has acquired several books of customers totaling approximately 115,000 customers, along with 

brand names, for $44 million. 

Petra Nova Debt Repayment

NRG has guaranteed up to $124 million of Petra Nova's $248 million project debt to its lenders for purposes of debt repayment 
in the event Petra Nova is unable to meet its projected debt coverage covenant as stipulated in its financing agreements. The 
covenant test and possible repayment, or a portion thereof, are scheduled to occur in the third quarter of 2019. Once such payment 
is made, NRG's guarantee will terminate.

NOLs, Deferred Tax Assets and Uncertain Tax Position Implications, under ASC 740

As of December 31, 2018, the Company had domestic pre-tax book income of $468 million and a foreign pre-tax book loss 
of $1 million. For the year ended December 31, 2018, the Company generated an NOL of $8.0 billion due to a current year taxable 
loss.  As of December 31, 2018, the Company has cumulative domestic federal NOL carryforwards of $10.7 billion, which will 
begin  expiring  in  2031  and  cumulative  state  NOL  carryforwards  of  $5.6  billion.  NRG  also  has  cumulative  foreign  NOL 
carryforwards of $213 million, which do not have an expiration date. In addition to the above NOLs, NRG has a $442 million 
indefinite carryforward for interest deductions, as well as $381 million of tax credits to be utilized in future years. As a result of 
the Company's tax position, including the benefit of $9.6 billion of tax losses and worthless stock deduction upon GenOn emerging 
from bankruptcy, and based on current forecasts, the Company anticipates income tax payments, primarily due to state and local 
jurisdictions, of up to $20 million in 2019.

The Company has recorded short-term and long-term receivables of $35 million and $34 million, respectively, representing 
refundable AMT credits from the IRS, which are anticipated to be received from 2019 through 2022 pursuant to the 50% annual 
limitation as enacted by the Tax Act upon repeal of corporate AMT effective January 1, 2018. Of this amount, short-term and long-
term payables of $11 million each are due to GenOn for their share of minimum tax credits.

In addition to these amounts, the Company has $26 million of tax effected uncertain state tax benefits for which the Company 
has recorded a non-current tax liability of $30 million (including accrued interest) until such final resolution with the related taxing 
authority. 

The Company is no longer subject to U.S. federal income tax examinations for years prior to 2015.  With few exceptions, 

state and local income tax examinations are no longer open for years before 2010.

Off-Balance Sheet Arrangements

Obligations under Certain Guarantee Contracts

NRG and certain of its subsidiaries enter into guarantee arrangements in the normal course of business to facilitate commercial 
transactions with third parties. These arrangements include financial and performance guarantees, stand-by letters of credit, debt 
guarantees, surety bonds and indemnifications. See also Item 15 — Note 25  Guarantees, to the Consolidated Financial Statements 
for additional discussion.

Retained or Contingent Interests

NRG does not have any material retained or contingent interests in assets transferred to an unconsolidated entity.

Obligations Arising Out of a Variable Interest in an Unconsolidated Entity

Variable interest in Equity investments — As of December 31, 2018, NRG has several investments with an ownership interest 
percentage of 50% or less in energy and energy-related entities that are accounted for under the equity method of accounting.  One 
of these investments is considered a variable interest entity for which NRG is not the primary beneficiary.

NRG's  pro-rata  share  of  non-recourse  debt  held  by  unconsolidated  affiliates  was  approximately  $992  million  as  of 
December 31, 2018.  This indebtedness may restrict the ability of these subsidiaries to issue dividends or distributions to NRG. 
See also Item 15 — Note 15, Investments Accounted for by the Equity Method and Variable Interest Entities, to the Consolidated 
Financial Statements for additional discussion.

85

Contractual Obligations and Commercial Commitments

NRG has a variety of contractual obligations and other commercial commitments that represent prospective cash requirements 
in addition to the Company's capital expenditure programs. The following tables summarize NRG's contractual obligations and 
contingent  obligations  for  guarantees.  See  also  Item 15 — Note  11,  Debt  and  Capital  Leases,  Note  21,  Commitments  and

Fair Value of Derivative Instruments

NRG  may  enter  into  power  purchase  and  sales  contracts,  fuel  purchase  contracts  and  other  energy-related  financial 
instruments to mitigate variability in earnings due to fluctuations in spot market prices and to hedge fuel requirements at generation 
facilities or retail load obligations. In addition, in order to mitigate interest rate risk associated with the issuance of the Company's 
variable rate debt, NRG enters into interest rate swap agreements.

NRG's trading activities are subject to limits in accordance with the Company's Risk Management Policy. These contracts 
are recognized on the balance sheet at fair value and changes in the fair value of these derivative financial instruments are recognized 
in earnings.

The tables below disclose the activities that include both exchange and non-exchange traded contracts accounted for at fair 
value in accordance with ASC 820, Fair Value Measurements and Disclosures, or ASC 820. Specifically, these tables disaggregate 
realized and unrealized changes in fair value; disaggregate estimated fair values at December 31, 2018, based on their level within 
the fair value hierarchy defined in ASC 820; and indicate the maturities of contracts at December 31, 2018.  For a full discussion 
of the Company's valuation methodology of its contracts, see Derivative Fair Value Measurements in Item 15 — Note 4, Fair 
Value of Financial Instruments, to the Consolidated Financial Statements.

The Company has elected to disclose derivative assets and liabilities on a trade-by-trade basis and does not offset amounts 
at the counterparty master agreement level. Also, collateral received or posted on the Company's derivative assets or liabilities are 
recorded on a separate line item on the balance sheet. Consequently, the magnitude of the changes in individual current and non-
current derivative assets or liabilities is higher than the underlying credit and market risk of the Company's portfolio. As discussed 
in Item 7A — Quantitative and Qualitative Disclosures About Market Risk, Commodity Price Risk, NRG measures the sensitivity 
of the Company's portfolio to potential changes in market prices using VaR, a statistical model which attempts to predict risk of 
loss based on market price and volatility. NRG's risk management policy places a limit on one-day holding period VaR, which 
limits  the  Company's  net  open  position.   As  the  Company's  trade-by-trade  derivative  accounting  results  in  a  gross-up  of  the 
Company's derivative assets and liabilities, the net derivative assets and liability position is a better indicator of NRG's hedging 
activity.  As of December 31, 2018, NRG's net derivative asset was $104 million, an increase to total fair value of $1 million as 
compared to December 31, 2017.  This increase was primarily driven by gains in fair value and contracts acquired during the 
period, largely offset by roll off trades that were settled during the period.

Based on a sensitivity analysis using simplified assumptions, the impact of a $0.50 per MMBtu increase in natural gas prices 
across the term of the derivative contracts would result in a decrease of approximately $230 million in the net value of derivatives 
as of December 31, 2018.

The impact of a $0.50 per MMBtu decrease in natural gas prices across the term of the derivative contracts would result 

in an increase of approximately $221 million in the net value of derivatives as of December 31, 2018.

Critical Accounting Policies and Estimates

NRG's discussion and analysis of the financial condition and results of operations are based upon the Consolidated Financial 
Statements,  which  have  been  prepared  in  accordance  with GAAP.  The  preparation  of  these  financial  statements  and  related 
disclosures in compliance with GAAP requires the application of appropriate technical accounting rules and guidance as well as 
the  use  of  estimates  and  judgments  that  affect  the  reported  amounts  of  assets,  liabilities,  revenues  and  expenses,  and  related 
disclosures  of  contingent  assets  and  liabilities. The  application  of  these  policies  involves  judgments  regarding  future  events, 
including the likelihood of success of particular projects, legal and regulatory challenges, and the fair value of certain assets and 
liabilities. These judgments, in and of themselves, could materially affect the financial statements and disclosures based on varying 
assumptions, which may be appropriate to use. In addition, the financial and operating environment may also have a significant 
effect, not only on the operation of the business, but on the results reported through the application of accounting measures used 
in preparing the financial statements and related disclosures, even if the nature of the accounting policies have not changed.

On  an  ongoing  basis,  NRG  evaluates  these  estimates,  utilizing  historic  experience,  consultation  with  experts  and  other 
methods the Company considers reasonable. In any event, actual results may differ substantially from the Company's estimates. 
Any effects on the Company's business, financial position or results of operations resulting from revisions to these estimates are 
recorded in the period in which the information that gives rise to the revision becomes known.

NRG's significant accounting policies are summarized in Item 15 — Note 2, Summary of Significant Accounting Policies, 
to the consolidated financial statements. The Company identifies its most critical accounting policies as those that are the most 
pervasive and important to the portrayal of the Company's financial position and results of operations, and that require the most 
difficult, subjective and/or complex judgments by management regarding estimates about matters that are inherently uncertain.

Derivative Instruments

The Company follows the guidance of ASC 815 to account for derivative instruments. ASC 815 requires the Company to 
mark-to-market all derivative instruments on the balance sheet and recognize changes in the fair value of non-hedge derivative 
instruments immediately in earnings.  In certain cases, NRG may apply hedge accounting to the Company's derivative instruments. 
The criteria used to determine if hedge accounting treatment is appropriate are: (i) the designation of the hedge to an underlying 
exposure; (ii) whether the overall risk is being reduced; and (iii) if there is a correlation between the changes in fair value of the 
derivative instrument and the underlying hedged item.  Changes in the fair value of derivatives instruments accounted for as hedges 
are deferred and recorded as a component of OCI and subsequently recognized in earnings when the hedged transactions occur.

For purposes of measuring the fair value of derivative instruments, NRG uses quoted exchange prices and broker quotes.  
When external prices are not available, NRG uses internal models to determine the fair value.  These internal models include 
assumptions of the future prices of energy commodities based on the specific market in which the energy commodity is being 
purchased or sold, using externally available forward market pricing curves for all periods possible under the pricing model.  In 
order to qualify the derivative instruments for hedged transactions, NRG estimates the forecasted borrowings for interest rate 
swaps occurring within a specified time period. Judgments related to the probability of forecasted borrowings are based on the 
estimated timing of project construction, which can vary based on various factors.  The probability that forecasted borrowings 
will occur by the end of a specified time period could change the results of operations by requiring amounts currently classified 
in OCI to be reclassified into earnings, creating increased variability in the Company's earnings.  These estimations are considered 
to be critical accounting estimates.

Certain derivative instruments that meet the criteria for derivative accounting treatment also qualify for a scope exception 
to derivative accounting, as they are considered to be NPNS.  The availability of this exception is based upon the assumption that 
NRG has the ability and it is probable to deliver or take delivery of the underlying item.  These assumptions are based on available 
baseload capacity, internal forecasts of sales and generation and historical physical delivery on contracts.  Derivatives that are 
considered to be NPNS are exempt from derivative accounting treatment and are accounted for under accrual accounting.  If it is 
determined that a transaction designated as NPNS no longer meets the scope exception due to changes in estimates, the related 
contract would be recorded on the balance sheet at fair value combined with the immediate recognition through earnings.

Income Taxes and Valuation Allowance for Deferred Tax Assets

As of December 31, 2018, NRG had a valuation allowance of $3.8 billion. This amount is comprised of domestic federal 
net deferred tax assets of approximately $3.3 billion, domestic state net deferred tax assets of $454 million, foreign net operating 
loss carryforwards of $62 million and foreign capital loss carryforwards of approximately $1 million.  The Company believes it 
is more likely than not that the results of future operations will not generate sufficient taxable income which includes the future 
reversal of existing taxable temporary differences to realize deferred tax assets, requiring a valuation allowance to be recorded. 

NRG continues to be under audit for multiple years by taxing authorities in other jurisdictions.  Considerable judgment is 
required to determine the tax treatment of a particular item that involves interpretations of complex tax laws, including the impact 
of the Tax Cuts and Jobs Act effective December 22, 2017.  NRG is subject to examination by taxing authorities for income tax 
returns filed in the U.S. federal jurisdiction and various state and foreign jurisdictions, including operations located in Australia.  

The Company is no longer subject to U.S. federal income tax examinations for years prior to 2015.  With few exceptions, 

state and local income tax examinations are no longer open for years before 2010.

Evaluation of Assets for Impairment and Other-Than-Temporary Decline in Value

In accordance with ASC 360, Property, Plant, and Equipment, or ASC 360, NRG evaluates property, plant and equipment 
and certain intangible assets for impairment whenever indicators of impairment exist. Examples of such indicators or events are:

• 

• 

Significant decrease in the market price of a long-lived asset;

Significant adverse change in the manner an asset is being used or its physical condition;

•  Adverse business climate;

•  Accumulation of costs significantly in excess of the amount originally expected for the construction or acquisition of an 

asset;

•  Current period loss combined with a history of losses or the projection of future losses; and

•  Change in the Company's intent about an asset from an intent to hold to a greater than 50% likelihood that an asset will 

be sold, or disposed of before the end of its previously estimated useful life

89

Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to the future 
net cash flows expected to be generated by the asset, through considering project specific assumptions for long-term power prices, 
escalated future project operating costs and expected plant operations. If such assets are considered to be impaired, the impairment 
to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets by 
factoring in the different courses of action available to the Company. Generally, fair value will be determined using valuation 
techniques such as the present value of expected future cash flows. NRG uses its best estimates in making these evaluations and 
considers various factors, including forward price curves for energy, fuel and operating costs. However, actual future market prices 
and project costs could vary from the assumptions used in the Company's estimates, and the impact of such variations could be 
material.

For assets to be held and used, if the Company determines that the undiscounted cash flows from the asset are less than the 
carrying amount of the asset, NRG must estimate fair value to determine the amount of any impairment loss. Assets held-for-sale 
are reported at the lower of the carrying amount or fair value less the cost to sell. The estimation of fair value under ASC 360, 
whether in conjunction with an asset to be held and used or with an asset held-for-sale, and the evaluation of asset impairment 
are, by their nature, subjective. NRG considers quoted market prices in active markets to the extent they are available. In the 
absence of such information, the Company may consider prices of similar assets, consult with brokers, or employ other valuation 
techniques. NRG will also discount the estimated future cash flows associated with the asset using a single interest rate representative 
of the risk involved with such an investment or employ an expected present value method that probability-weights a range of 
possible outcomes. The use of these methods involves the same inherent uncertainty of future cash flows as previously discussed 
with respect to undiscounted cash flows. Actual future market prices and project costs could vary from those used in the Company's 
estimates, and the impact of such variations could be material.  

Annually,  during  the  fourth  quarter,  the  Company  revises  its  views  of  power  and  fuel  prices  including  the  Company's 
fundamental  view  for  long  term  prices,  forecasted  generation  and  operating  and  capital  expenditures,  in  connection  with  the 
preparation of its annual budget.  Changes to the Company's views of long term power and fuel prices impacted the Company’s 
projections of profitability, based on management's estimate of supply and demand within the sub-markets for its operations and 
the physical and economic characteristics of each of its businesses. During the fourth quarter of 2018, the Company completed 
its annual budget and revised its view of long-term power and fuel prices and the corresponding impact on estimated cash flows 
associated with its long-lived assets. There were no significant changes to the Company's long-term view of natural gas prices 
despite management's expectation of continued trends towards more renewables and energy storage. There were minimal changes 
to the long-term view of energy and capacity prices, which did not have a significant negative impact on the Company's coal, 
nuclear, and renewable facilities.

The  following  long-lived  asset  impairment  was  recorded  during  2018,  as  further  described  in  Item 15 —Note  9,  Asset 

Impairments, to the consolidated financial statements:

Guam— During the fourth quarter of 2018, the Company concluded its wholly-owned subsidiary, NRG Solar Guam, LLC, 
was held for sale after board approval and advanced negotiations to sell the business. Accordingly, the Company recorded the 
assets  and  liabilities  at  fair  market  value  as  of  December 31,  2018  based  on  the  contractual  sale  price,  which  resulted  in  an 
impairment loss of $12 million. The sale was completed on February 20, 2019. 

Keystone and Conemaugh — On June 29, 2018, the Company entered into an agreement to sell its approximately 3.7%
interests  in  the  Keystone  and  Conemaugh  generating  stations.   The  Company  recorded  impairment  losses  of  $14  million  for 
Keystone and $14 million for Conemaugh to adjust the carrying amount of the assets to fair value based on the contractual sale 
price. The transaction closed on September 5, 2018.

Dunkirk — During the second quarter of 2018, NRG ceased its development of the project to add gas capability at the Dunkirk 
generating station. The project was put on hold in 2015 pending the resolution of a lawsuit filed by Entergy Corporation against 
the NYPSC, which challenged the legality of its contract with Dunkirk.  The lawsuit was later dropped and development continued, 
but the delay imposed a new requirement on Dunkirk to enter into the NYISO interconnection study process. The NYISO studies 
have concluded that extensive electric system upgrades would be necessary for the station to return to service. This would cause 
the  Company  to  incur  a  material  increase  in  cost  and  delay  the  project  schedule  that  would  render  the  project  impractical. 
Consequently, the Company has recorded an impairment loss of $46 million, reducing the carrying amount of the related assets 
to $0. 

Other Impairments — As of December 31, 2018, the Company recorded additional impairment losses of approximately $13 
million. These impairment losses were primarily to record the value of certain long-lived assets, including property, plant and 
equipment and intangible assets, at fair market value at the date of sale or in connection with an impairment indicator. 

90

Equity and Cost Method Investments — NRG is also required to evaluate its equity method and cost method investments 
to determine whether or not they are impaired in accordance with ASC 323, Investments - Equity Method and Joint Ventures, or 
ASC 323.  The standard for determining whether an impairment must be recorded under ASC 323 is whether a decline in the value 
is considered an other-than-temporary decline in value.  The evaluation and measurement of impairments under ASC 323 involves 
the same uncertainties as described for long-lived assets that the Company owns directly and accounts for in accordance with ASC 
360.  Similarly, the estimates that NRG makes with respect to its equity and cost method investments are subjective, and the impact 
of variations in these estimates could be material.  Additionally, if the projects in which the Company holds these investments 
recognize an impairment under the provisions of ASC 360, NRG would record its proportionate share of that impairment loss and 
would evaluate its investment for an other-than-temporary decline in value under ASC 323.  During the year ended December 31, 
2018, the Company recorded impairment losses on its equity method investments of $15 million due to declines in value.

  Goodwill and Other Intangible Assets 

At December 31, 2018, NRG reported goodwill of $573 million, consisting of $165 million associated with the acquisition 
of Midwest Generation and $408 million for retail business acquisitions. The balance of goodwill increased by $34 million in 
2018 due to the acquisition of XOOM. 

 The  Company  applies ASC  805,  Business  Combinations,  or ASC  805,  and ASC  350,  to  account  for  its  goodwill  and 
intangible assets.  Under these standards, the Company amortizes all finite-lived intangible assets over their respective estimated 
weighted-average useful lives, while goodwill has an indefinite life and is not amortized.  Goodwill is tested for impairment at 
least annually, or more frequently whenever an event or change in circumstances occurs that would more likely than not reduce 
the fair value of a reporting unit below its carrying amount.  The Company tests goodwill for impairment at the reporting unit 
level, which is identified by assessing whether the components of the Company's operating segments constitute businesses for 
which discrete financial information is available and whether segment management regularly reviews the operating results of 
those components.  The Company performs the annual goodwill impairment assessment as of December 31 or when events or 
changes in circumstances indicate that the carrying value may not be recoverable. The Company first assesses qualitative factors 
to determine whether it is more likely than not that an impairment has occurred.  In the absence of sufficient qualitative factors, 
the Company performs a quantitative assessment by determining the fair value of the reporting unit and comparing to its book 
value. If it is determined that the fair value of a reporting unit is below its carrying amount, where necessary, the Company's 
goodwill will be impaired at that time.

The Company performed its qualitative assessment of macroeconomic, industry and market events and circumstances, and 
the overall financial performance of the NRG Business Solutions and Commodity Retail reporting units.  The Company determined 
it was more likely than not that the fair value of the goodwill attributed to these reporting units were more than their carrying 
amount and accordingly, no impairment existed for the year ended December 31, 2018.

The Company performed a quantitative assessment for the reporting units in the following table.  The Company determined 
the fair value of these reporting units using primarily an income approach.  Under the income approach, the Company estimated 
the fair value of the reporting units' invested capital exceeds its carrying value and, as such, the Company concluded that goodwill 
associated with the reporting units in the following table is not impaired as of December 31, 2018: 

Reporting Unit

Midwest Generation (Generation Segment)

Texas Non-Commodity (Retail Segment)

% Fair Value Over
Carrying Value

132%

135%

The Company believes the methodology and assumptions used in its quantitative assessment are consistent with the views 

of market participants.  Significant inputs to the determination of fair value were as follows:

•  The Company applied a discounted cash flow methodology to the long-term forecasts for all of the plants in the region. 
The significant assumptions used to derive the long-term budgets used in the income approach are affected by the following 
key inputs:  

  The Company's views of power and fuel prices consider market prices for the first five-year period and the 
Company's fundamental view for the longer term, driven by the Company's long-term view of the price of natural 
gas.  The Company's fundamental view for the longer term reflects the implied power price and heat rate that 
would support new build of a combined cycle gas plant. The price of natural gas plays an important role in 
setting the price of electricity in many of the regions where NRG operates power plants.  Hedging is included 
to the extent of contracts already in place; 

91

  The  Company's  estimate  of  generation,  fuel  costs,  capital  expenditure  requirements  and  the  existing  and 

anticipated impact of environmental regulations; 

  The Company's fundamental view for the longer term, cash flows for the plants in the region were included in 

the fair value calculation through the end of each plants' estimated useful life; and

Projected generation and resulting energy gross margin in the long-term forecasts is based on an hourly dispatch 
that simulates dispatch of each unit into the power market.  The dispatch simulation is based on power prices, 
fuel prices, and the physical and economic characteristics of each plant 

•  The  Company  applied  a  discounted  cash  flow  methodology  to  the  long-term  budget  for  the Texas  Non-Commodity 
reporting unit.  The significant assumptions used to derive the long-term budgets used in the income approach are affected 
by the following key inputs: a terminal value utilizing assumed growth rates and discount rates that reflect the inherent 
cash flow risk for each reporting unit.

Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions and factors.  
As a result, there can be no assurance that the estimates and assumptions made for purposes of the annual goodwill impairment 
test will prove to be accurate predictions of the future. 

Contingencies

NRG records reserves for estimated losses from contingencies when information available indicates that a loss is probable 
and the amount of the loss, or range of loss, can be reasonably estimated. Gain contingencies are not recorded until management 
determines it is certain that the future event will become or does become a reality.  Such determinations are subject to interpretations 
of current facts and circumstances, forecasts of future events, and estimates of the financial impacts of such events.  NRG describes 
in detail its contingencies in Item 15 — Note 21, Commitments and Contingencies, to the consolidated financial statements.

Item 7A — Quantitative and Qualitative Disclosures About Market Risk 

NRG is exposed to several market risks in the Company's normal business activities.  Market risk is the potential loss that 
may result from market changes associated with the Company's retail businesses, merchant power generation, or with an existing 
or forecasted financial or commodity transaction.  The types of market risks the Company is exposed to are commodity price risk, 
interest rate risk, liquidity risk, credit risk and currency exchange risk.  In order to manage these risks, the Company uses various 
fixed-price forward purchase and sales contracts, futures and option contracts traded on NYMEX, and swaps and options traded 
in the over-the-counter financial markets to:

•  Manage and hedge fixed-price purchase and sales commitments;

•  Manage and hedge exposure to variable rate debt obligations;

•  Reduce exposure to the volatility of cash market prices, and

•  Hedge fuel requirements for the Company's generating facilities.

Commodity Price Risk

Commodity price risks result from exposures to changes in spot prices, forward prices, volatilities, and correlations between 
various commodities, such as natural gas, electricity, coal, oil, and emissions credits.  NRG manages the commodity price risk of 
the Company's merchant generation operations and load serving obligations by entering into various derivative or non-derivative 
instruments  to  hedge  the  variability  in  future  cash  flows  from  forecasted  sales  and  purchases  of  electricity  and  fuel.   These 
instruments include forwards, futures, swaps, and option contracts traded on various exchanges, such as NYMEX and ICE, as 
well as over-the-counter markets.  The portion of forecasted transactions hedged may vary based upon management's assessment 
of market, weather, operation and other factors. 

While some of the contracts the Company uses to manage risk represent commodities or instruments for which prices are 
available from external sources, other commodities and certain contracts are not actively traded and are valued using other pricing 
sources and modeling techniques to determine expected future market prices, contract quantities, or both.  NRG uses the Company's 
best estimates to determine the fair value of those derivative contracts.  However, it is likely that future market prices could vary 
from those used in recording mark-to-market derivative instrument valuation and such variations could be material.

NRG measures the risk of the Company's portfolio using several analytical methods, including sensitivity tests, scenario 
tests, stress tests, position reports, and VaR.  NRG uses a Monte Carlo simulation based VaR model to estimate the potential loss 
in the fair value of the Company's energy assets and liabilities, which includes generation assets, load obligations, and bilateral 
physical and financial transactions.  The key assumptions for the Company's VaR model include: (i) lognormal distribution of 
prices; (ii) one-day holding period; (iii) 95% confidence interval; (iv) rolling 36-month forward looking period; and (v) market 
implied volatilities and historical price correlations.

 As of December 31, 2018, the VaR for NRG's commodity portfolio, including generation assets, load obligations and bilateral 

physical and financial transactions calculated using the VaR model was $44 million.

The following table summarizes average, maximum and minimum VaR for NRG for the years ended December 31, 2018

and 2017:

Due  to  the  inherent  limitations  of  statistical  measures  such  as VaR,  the  evolving  nature  of  the  competitive  markets  for 
electricity and related derivatives, and the seasonality of changes in market prices, the VaR calculation may not capture the full 
extent of commodity price exposure.  As a result, actual changes in the fair value of mark-to-market energy assets and liabilities 
could differ from the calculated VaR, and such changes could have a material impact on the Company's financial results.

In order to provide additional information, the Company also uses VaR to estimate the potential loss of derivative financial 
instruments that are subject to mark-to-market accounting. These derivative instruments include transactions that were entered 
into  for  both  asset  management  and  trading  purposes. The VaR  for  the  derivative  financial  instruments  calculated  using  the 
diversified VaR model for the entire term of these instruments entered into for both asset management and trading was $14 million
as of December 31, 2018, primarily driven by asset-backed transactions.

93

Interest Rate Risk

NRG is exposed to fluctuations in interest rates through the Company's issuance of fixed rate and variable rate debt.  Exposures 
to interest rate fluctuations may be mitigated by entering into derivative instruments known as interest rate swaps, caps, collars 
and put or call options. These contracts reduce exposure to interest rate volatility and result in primarily fixed rate debt obligations 
when  taking  into  account  the  combination  of  the  variable  rate  debt  and  the  interest  rate  derivative  instrument.  NRG's  risk 
management policies allow the Company to reduce interest rate exposure from variable rate debt obligations.

In addition to those discussed above, the Company's project subsidiaries enter into interest rate swaps, intended to hedge 
the risks associated with interest rates on non-recourse project level debt. See Item 15 — Note 11, Debt and Capital Leases, to 
the Consolidated Financial Statements, for more information about interest rate swaps of the Company's project subsidiaries. 

If all of the above swaps had been discontinued on December 31, 2018, the counterparties would have owed the Company 
$37  million.  Based  on  the  investment  grade  rating  of  the  counterparties,  NRG  believes  its  exposure  to  credit  risk  due  to 
nonperformance by counterparties to its hedge contracts to be insignificant.

NRG has both long and short-term debt instruments that subject the Company to the risk of loss associated with movements 
in market interest rates. As of December 31, 2018, a 1% change in interest rates would result in a $7 million change in interest 
expense on a rolling twelve month basis.

As of December 31, 2018, the Company's debt fair value was $6.7 billion and carrying value was $6.6 billion. NRG estimates 
that a 1% decrease in market interest rates would have increased the fair value of the Company's long-term debt by $510 million.

Liquidity Risk

Liquidity risk arises from the general funding needs of the Company's activities and in the management of the Company's 
assets and liabilities. The Company is currently exposed to additional collateral posting if natural gas prices decline primarily due 
to the long natural gas equivalent position at various exchanges used to hedge NRG's retail supply load obligations.

Based on a sensitivity analysis for power and gas positions under marginable contracts, a $0.50 per MMBtu change in natural 
gas prices across the term of the marginable contracts would cause a change in margin collateral posted of approximately $125 
million as of December 31, 2018, and a 1.00 MMBtu/MWh change in heat rates for heat rate positions would result in a change 
in margin collateral posted of approximately $62 million as of December 31, 2018. This analysis uses simplified assumptions and 
is calculated based on portfolio composition and margin-related contract provisions as of December 31, 2018.

Counterparty Credit Risk

Credit risk relates to the risk of loss resulting from non-performance or non-payment by counterparties pursuant to the terms 
of  their  contractual  obligations.  The  Company  monitors  and  manages  credit  risk  through  credit  policies  that  include:  (i) an 
established credit approval process; (ii) a daily monitoring of counterparties' credit limits; (iii) the use of credit mitigation measures 
such as margin, collateral, prepayment arrangements, or volumetric limits; (iv) the use of payment netting agreements; and (v) the 
use of master netting agreements that allow for the netting of positive and negative exposures of various contracts associated with 
a single counterparty. Risks surrounding counterparty performance and credit could ultimately impact the amount and timing of 
expected cash flows. The Company seeks to mitigate counterparty risk by having a diversified portfolio of counterparties. The 
Company also has credit protection within various agreements to call on additional collateral support if and when necessary. Cash 
margin is collected and held at the Company to cover the credit risk of the counterparty until positions settle.

94

As of December 31, 2018, aggregate counterparty credit exposure to a significant portion of the Company's counterparties 
totaled $301 million, of which the Company held collateral (cash and letters of credit) against those positions of $123 million 
resulting in a net exposure of $180 million. Approximately 66% of the Company's exposure before collateral is expected to roll 
off by the end of 2020. The following table highlights the net counterparty credit exposure by industry sector and by counterparty 
credit quality. Net counterparty credit exposure is defined as the aggregate net asset position for NRG with counterparties where 
netting  is  permitted  under  the  enabling  agreement  and  includes  all  cash  flow,  mark-to-market,  NPNS,  and  non-derivative 
transactions. As of December 31, 2018, the aggregate credit exposure is shown net of collateral held, and includes amounts net 
of receivables or payables.

(a)  Counterparty credit exposure excludes uranium and coal transportation contracts because of the unavailability of market prices
(b)  The figures in the tables above exclude potential counterparty credit exposure related to RTOs, ISOs, registered commodity exchanges and certain long 

term contracts

The Company currently has no exposure to any individual wholesale counterparty in excess of 10% of the total net exposure 
discussed above as of December 31, 2018.  Changes in hedge positions and market prices will affect credit exposure and counterparty 
concentration. Given the credit quality, diversification and term of the exposure in the portfolio, the Company does not anticipate 
a material impact on its financial position or results of operations from nonperformance by any counterparty. 

RTOs and ISOs

The Company participates in the organized markets of CAISO, ERCOT, ISO-NE, MISO, NYISO and PJM, known as RTOs 
or ISOs. Trading in these markets is approved by FERC, or in the case of ERCOT, approved by the PUCT and include credit 
policies that, under certain circumstances, require that losses arising from the default of one member on spot market transactions 
be shared by the remaining participants. As a result, the counterparty credit risk to these markets is limited to NRG’s applicable 
share of the overall market and are excluded from the above exposures.  

Exchange Traded Transactions

The Company enters into commodity transactions on registered exchanges, notably ICE and NYMEX. These clearinghouses 
act as the counterparty and transactions are subject to extensive collateral and margining requirements. As a result, these commodity 
transactions have limited counterparty credit risk.

95

Long Term Contracts

Counterparty credit exposure described above excludes credit risk exposure under certain long term contracts, including 
California tolling agreements and solar PPAs. As external sources or observable market quotes are not available to estimate such 
exposure, the Company values these contracts based on various techniques including, but not limited to, internal models based 
on a fundamental analysis of the market and extrapolation of observable market data with similar characteristics. Based on these 
valuation techniques, as of December 31, 2018, aggregate credit risk exposure managed by NRG to these counterparties was 
approximately $434 million for the next five years. This amount excludes potential credit exposures for projects with long-term 
PPAs that have not reached commercial operations and any exposure for entities classified as a discontinued operation. 

NRG through its unconsolidated affiliates Ivanpah and Agua Caliente has exposure to PG&E of approximately $321 million 
for the next five years. As a result of the bankruptcy filing by PG&E on January 29, 2019, it is uncertain whether and to what 
extent the bankruptcy may have on these contracts. For further discussion see Note 15  Investments Accounted for by the Equity 
Method and Variable Interest Entities. 

Retail Customer Credit Risk 

NRG is exposed to retail credit risk through its retail electricity providers, which serve C&I customers and the Mass market. 
Retail credit risk results in losses when a customer fails to pay for services rendered.  The losses could be incurred from nonpayment 
of customer accounts receivable and any in-the-money forward value.  NRG manages retail credit risk through the use of established 
credit policies that include monitoring of the portfolio, and the use of credit mitigation measures such as deposits or prepayment 
arrangements. 

As of December 31, 2018, the Company's retail customer credit exposure to C&I and Mass customers was diversified across 
many customers and various industries, as well as government entities. The Company is also subject to risk with respect to its 
residential solar customers. The Company's bad debt expense resulting from credit risk was $85 million, $68 million, and $45 
million  for  the  years  ending  December  31,  2018,  2017,  and  2016,  respectively.  Current  economic  conditions  may  affect  the 
Company's customers' ability to pay bills in a timely manner, which could increase customer delinquencies and may lead to an 
increase in bad debt expense.

Certain of the Company's hedging agreements contain provisions that require the Company to post additional collateral if 
the counterparty determines that there has been deterioration in credit quality, generally termed "adequate assurance" under the 
agreements, or require the Company to post additional collateral if there were a one notch downgrade in the Company's credit 
rating.  The collateral required for contracts that have adequate assurance clauses that are in a net liability position as of December 31, 
2018 was $16 million.  The collateral required for contracts with credit rating contingent features that are in a net liability position 
as of December 31, 2018 was $14 million.  The Company is also a party to certain marginable agreements under which it has a 
net liability position, but the counterparty has not called for the collateral due, which is approximately $11 million as of December 31, 
2018.

Currency Exchange Risk

NRG's foreign earnings and investments may be subject to foreign currency exchange risk, which NRG generally does not 
hedge.  As these earnings and investments are not material to NRG's consolidated results, the Company's foreign currency exposure 
is limited.

Item 9A — Controls and Procedures

Conclusion  Regarding  the  Effectiveness  of  Disclosure  Controls  and  Procedures  and  Internal  Control  Over  Financial 
Reporting

Under the supervision and with the participation of NRG's management, including its principal executive officer, principal 
financial officer and principal accounting officer, NRG conducted an evaluation of the effectiveness of the design and operation 
of its disclosure controls and procedures, as such term is defined in Rules 13a-15(e) or 15d-15(e) of the Exchange Act. Based on 
this evaluation, the Company's principal executive officer, principal financial officer and principal accounting officer concluded 
that the disclosure controls and procedures were effective as of the end of the period covered by this Annual Report on Form 10-
K. Management's report on the Company's internal control over financial reporting and the report of the Company's independent 
registered public accounting firm are incorporated under the caption "Management's Report on Internal Control over Financial 
Reporting" and under the caption "Report of Independent Registered Public Accounting Firm" in this Annual Report on Form 10-
K for the fiscal year ended December 31, 2018.

Changes in Internal Control over Financial Reporting

There were no changes in NRG’s internal control over financial reporting (as such term is defined in Rule 13a-15(f) under 
the Exchange Act) that occurred in the fourth quarter of 2018 that materially affected, or are reasonably likely to materially affect, 
NRG’s internal control over financial reporting.

Inherent Limitations over Internal Controls

NRG's  internal  control  over  financial  reporting  is  designed  to  provide  reasonable  assurance  regarding  the  reliability  of 
financial reporting and the preparation of consolidated financial statements for external purposes in accordance with GAAP. The 
Company's internal control over financial reporting includes those policies and procedures that:

1.  Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions 

of the Company's assets;

2.  Provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial 
statements in accordance with GAAP, and that the Company's receipts and expenditures are being made only in accordance 
with authorizations of its management and directors; and

3.  Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of 

the Company's assets that could have a material effect on the consolidated financial statements

Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because 
of its inherent limitations, including the possibility of human error and circumvention by collusion or overriding of controls. 
Accordingly, even an effective internal control system may not prevent or detect material misstatements on a timely basis. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because 
of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

Management's Report on Internal Control over Financial Reporting

The  Company's  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial 
reporting, as such term is defined in Exchange Act Rule 13a-15(f). Under the supervision and with the participation of the Company's 
management, including its principal executive officer, principal financial officer and principal accounting officer, the Company 
conducted an evaluation of the effectiveness of its internal control over financial reporting based on the framework in Internal 
Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. 
Based on the Company's evaluation under the framework in Internal Control — Integrated Framework (2013), the Company's 
management concluded that its internal control over financial reporting was effective as of December 31, 2018.

On June 1, 2018, we acquired XOOM Energy, LLC, as further described in Note 3,  Acquisitions, Discontinued Operations 
and Dispositions. XOOM Energy, LLC's assets comprised approximately 2.1% of the Company's total assets as of December 31, 
2018 and approximately 2.3% of the Company's total revenues for the year ended December 31, 2018. As of December 31, 2018, 
we are in the process of evaluating the internal controls of the acquired business and integrating it into our existing operations. 

97

The acquired business has, therefore, been excluded from management's assessment of internal control over financial reporting 
for the year ended December 31, 2018.

The effectiveness of the Company's internal control over financial reporting as of December 31, 2018 has been audited by 
KPMG LLP, the Company's independent registered public accounting firm, as stated in its report which is included in this Annual 
Report on Form 10 K.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders
NRG Energy, Inc.:

Opinion on Internal Control Over Financial Reporting

We have audited NRG Energy, Inc.’s and subsidiaries (the Company) internal control over financial reporting as of December 31, 
2018, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring 
Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal 
control over financial reporting as of December 31, 2018, based on criteria established in Internal Control — Integrated Framework 
(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the consolidated balance sheets of the Company as of December 31, 2018 and 2017, the related consolidated statements 
of operations, comprehensive income/(loss), stockholders’ equity, and cash flows for each of the years in the three-year period 
ended  December 31,  2018,  and  the  related  notes  and  financial  statement  schedule  II  (collectively,  the  consolidated  financial 
statements), and our report dated February 28, 2019 expressed an unqualified opinion on those consolidated financial statements.

Management  excluded  XOOM  Energy,  LLC  (XOOM),  acquired  by  the  Company  during  2018,  from  their  assessment  of  the 
effectiveness of the Company's internal control over financial reporting as of December 31, 2018. XOOM's assets comprised 
approximately 2.1% of the Company's total assets as of December 31, 2018 and approximately 2.3% of the Company's total 
revenues for the year ended December 31, 2018. Our audit of the Company's internal control over financial reporting also excluded 
XOOM.

Basis for Opinion

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment 
of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal 
Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial 
reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with 
respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities 
and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material 
respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial 
reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of 
internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary 
in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability 
of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted 
accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain 
to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets 
of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial 
statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are 
being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable 
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that 
could have a material effect on the financial statements.

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because 
of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

(1)  Consists of shares issuable under the NRG LTIP and the ESPP.  The NRG LTIP became effective upon the Company's emergence from bankruptcy.  On 
April 27, 2017, the NRG LTIP was amended and restated to increase the number of shares available for issuance to 25,000,000.  The ESPP, as amended and 
restated, was approved by the Company's stockholders on April 27, 2017, and became effective April 28, 2017.  As of December 31, 2018, there were 
2,931,188 shares reserved from the Company's treasury shares for the ESPP.

(2)  Consists of shares issuable under the NRG GenOn LTIP.  On December 14, 2012, in connection with the Merger, NRG assumed the GenOn Energy, Inc. 
2010 Omnibus Incentive Plan and changed the name to the NRG 2010 Stock Plan for GenOn Employees, or the NRG GenOn LTIP.  While the GenOn 
Energy, Inc. 2010 Omnibus Incentive Plan was previously approved by stockholders of RRI Energy, Inc. before it became GenOn, the plan is listed as “not 
approved” because the NRG GenOn LTIP was not subject to separate line item approval by NRG's stockholders when the Merger (which included the 
assumption of this plan) was approved.  As part of the Merger, NRG also assumed the GenOn Energy, Inc. 2002 Long-Term Incentive Plan, the GenOn 
Energy, Inc. 2002 Stock Plan, and the Mirant Corporation 2005 Omnibus Incentive Compensation Plan.  NRG has no intention of making any grants or 
awards of its own equity securities under these plans.  The number of securities to be issued upon the exercise of outstanding awards under these plans is 
217,709 at a weighted-average exercise price of $34.13.  See Item 15 — Note 19, Stock-Based Compensation, to Consolidated Financial Statements for a 
discussion of the NRG GenOn LTIP.

(3)  Consists of 8,564,611 shares of common stock under NRG's LTIP and 2,931,188 shares of treasury stock reserved for issuance under the ESPP. 

(4)  Upon adoption of the NRG Amended and Restated LTIP effective April 27, 2017, no securities remain available for future issuance under the NRG GenOn 

LTIP.  See Note 19, Stock-Based Compensation, for additional information.

Both the NRG LTIP and the NRG GenOn LTIP provide for grants of stock options, restricted stock, market stock units, 
performance stock units, deferred stock units and dividend equivalent rights.  NRG's directors, officers and employees, as well as 
other individuals performing services for, or to whom an offer of employment has been extended by the Company, are eligible to 
receive grants under the NRG LTIP and the NRG GenOn LTIP.  However, participants eligible for the NRG LTIP at the time of 
the Merger are not eligible to receive grants under the NRG GenOn LTIP.  The purpose of the NRG LTIP and the NRG GenOn 
LTIP is to promote the Company's long-term growth and profitability by providing these individuals with incentives to maximize 
stockholder value and otherwise contribute to the Company's success and to enable the Company to attract, retain and reward the

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The the Stockholders and Board of Directors
NRG Energy, Inc.: 

Opinion on the Consolidated Financial Statements

We  have  audited  the  accompanying  consolidated  balance  sheets  of  NRG  Energy,  Inc.  and subsidiaries  (the  Company)  as  of 
December 31, 2018 and 2017, the related consolidated statements of operations, comprehensive income/(loss), stockholders' equity, 
and cash flows for each of the years in the three year period ended December 31, 2018, and the related notes and financial statement 
schedule II (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, 
in all material respects, the financial position of the Company as of December 31, 2018 and 2017, and the results of its operations 
and its cash flows for each of the years in the three year period ended December 31, 2018, in conformity with U.S. generally 
accepted accounting principles. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company's internal control over financial reporting as of December 31, 2018, based on criteria established in 
Internal  Control  -  Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway 
Commission, and our report dated February 28, 2019 expressed an unqualified opinion on the effectiveness of the Company's 
internal control over financial reporting.  

Change in Accounting Principle

As discussed in Note 2 to the consolidated financial statements, effective January 1, 2018, the Company has adopted Financial 
Accounting Standard Board-Accounting Standards Codification Topic 606, Revenue from Contracts with Customers, and related 
amendments.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an 
opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB 
and  are  required  to  be  independent  with  respect  to  the  Company  in  accordance  with  the  U.S. federal  securities  laws  and  the 
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether 
due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated 
financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included 
examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits 
also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the 
overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

(signed) KPMG LLP

We have served as the Company's auditor since 2004.

NRG ENERGY, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 — Nature of Business 

General

NRG Energy, Inc., or NRG or the Company, is an energy company built on dynamic retail brands with diverse generation 
assets. NRG brings the power of energy to consumers by producing, selling and delivering electricity and related products and 
services in major competitive power markets in the U.S. in a manner that delivers value to all of NRG's stakeholders. NRG is 
perfecting the integrated model by balancing retail load with generation supply within its deregulated markets, while evolving to 
a customer-driven business. The Company sells energy, services, and innovative, sustainable products and services directly to 
retail customers under the names "NRG" and "Reliant" and other brand names owned by NRG supported by approximately 23,000(a) 
MW of generation as of December 31, 2018.

Retail  is  a  consumer  facing  business  that  includes  residential  and  small  commercial  (Mass  Market)  consumers  and  the 
Company's  Business  Solutions  group,  which  includes  demand  response,  commodity  sales,  energy  efficiency  and  energy 
management solutions.  Products and services range from retail energy, portable solar and battery products home services, and a 
variety of bundled products, which combine energy with protection products, energy efficiency and renewable energy solutions, 
as well as other distributed and reliability products.

The Company's Generation business includes plant operations, commercial operations, EPC, asset management, energy 
services  and  other  critical  related  functions.  In  addition  to  the  traditional  functions  from  NRG's  wholesale  power  generation 
business, Generation also includes NRG's retained renewable generation business.

Discontinued Operations

On  December  31,  2018,  as  described  in  Note  3,  Acquisitions,  Discontinued  Operations  and  Dispositions,  the 
Company concluded that the sale of its South Central Portfolio to Cleco, excluding the Cottonwood facility, met held-for-sale 
criteria and should be presented as a discontinued operation, as the sale represented a strategic shift in the business in which NRG 
operates.  The  financial  information  for  all  historical  periods  has  been  recast  to  reflect  the  presentation  of  these  entities  as 
discontinued operations.

On August 31, 2018, as described in Note 3, Acquisitions, Discontinued Operations and Dispositions, NRG deconsolidated 
NRG Yield, Inc. and its Renewables Platform for financial reporting purposes.  The financial information for all historical periods 
has been recast to reflect the presentation of these entities, as well as the Carlsbad project, as discontinued operations.  As a result 
of the sale of NRG Yield, the Company no longer controls the Agua Caliente project. Due to this change in control, the Company 
has deconsolidated the Agua Caliente project from its financial results and has accounted for the project as an equity method 
investment. 

GenOn Chapter 11 Cases

On June 14, 2017, or the Petition Date, GenOn, along with GenOn Americas Generation and certain of their directly and 
indirectly-owned subsidiaries, or collectively the GenOn Entities, filed voluntary petitions for relief under Chapter 11, or the 
Chapter 11 Cases, of the U.S. Bankruptcy Code, or the Bankruptcy Code, in the U.S. Bankruptcy Court for the Southern District 
of Texas, Houston Division, or the Bankruptcy Court. GenOn Mid-Atlantic, as well as its consolidated subsidiaries, REMA and 
certain other subsidiaries, did not file for relief under Chapter 11. As a result of the bankruptcy filings and beginning on June 14, 
2017, GenOn and its subsidiaries were deconsolidated from NRG's consolidated financial statements. NRG determined that this 
disposal of GenOn and its subsidiaries is a discontinued operation and, accordingly, the financial information for all historical 
periods has been recast to reflect GenOn as a discontinued operation. GenOn's plan of reorganization was confirmed on December 
14, 2018.

Note 2 — Summary of Significant Accounting Policies 

Basis of Presentation and Principles of Consolidation

The Company's consolidated financial statements have been prepared in accordance with GAAP.  The ASC, established by 
the FASB, is the source of authoritative GAAP to be applied by nongovernmental entities.  In addition, the rules and interpretative 
releases of the SEC under authority of federal securities laws are also sources of authoritative U.S. GAAP for SEC registrants.

The consolidated financial statements include NRG's accounts and operations and those of its subsidiaries in which the 
Company has a controlling interest. All significant intercompany transactions and balances have been eliminated in consolidation.  
The usual condition for a controlling financial interest is ownership of a majority of the voting interests of an entity.  However, a 
controlling financial interest may also exist through arrangements that do not involve controlling voting interests.  As such, NRG 
applies the guidance of ASC 810, Consolidations, or ASC 810, to determine when an entity that is insufficiently capitalized or 
not controlled through its voting interests, referred to as a VIE, should be consolidated.

Net Income/(Loss) attributable to NRG Energy, Inc.

The Company's businesses are segregated into the Generation, Retail and corporate segments. Generation includes all power 
plant activities, domestic and international, as well as renewables. Retail includes Mass customers and Business Solutions, which 
includes C&I customers and other distributed and reliability products.  

As described in Note 3, Acquisitions, Discontinued Operations and Dispositions, the Company has determined that the South 
Central Portfolio, NRG Yield Inc. and its Renewables Platform, Carlsbad, and GenOn all qualified for treatment as a discontinued 
operation. The financial information for all historical periods has been recast to reflect the presentation of discontinued operations 
within the corporate segment.

Cash and Cash Equivalents

Cash and cash equivalents include highly liquid investments with an original maturity of three months or less at the time of 

purchase.

Funds Deposited by Counterparties

Funds deposited by counterparties consist of cash held by the Company as a result of collateral posting obligations from its 
counterparties. Some amounts are segregated into separate accounts that are not contractually restricted but, based on the Company's 
intention, are not available for the payment of general corporate obligations. Depending on market fluctuations and the settlement 
of the underlying contracts, the Company will refund this collateral to the hedge counterparties pursuant to the terms and conditions 
of the underlying trades. Since collateral requirements fluctuate daily and the Company cannot predict if any collateral will be 
held for more than twelve months, the funds deposited by counterparties are classified as a current asset on the Company's balance 
sheet, with an offsetting liability for this cash collateral received within current liabilities. As of December 31, 2016, $79 million 
of the cash collateral received was from GenOn, previously a consolidated subsidiary, and is included in cash collateral received 
in current liabilities as a result of deconsolidating GenOn, with the offset included in cash and cash equivalents.

Restricted cash consists primarily of funds held to satisfy the requirements of certain debt agreements and funds held within 

the Company's projects that are restricted in their use. 

 Trade Receivables and Allowance for Doubtful Accounts

Trade receivables are reported in the balance sheet at outstanding principal adjusted for any write-offs and the allowance 
for doubtful accounts.  For its retail business, the Company accrues an allowance for doubtful accounts based on estimates of 
uncollectible revenues by analyzing counterparty credit ratings (for commercial and industrial customers), historical collections, 
accounts receivable aging and other factors.  The retail business writes-off accounts receivable balances against the allowance for 
doubtful accounts when it determines a receivable is uncollectible.  In addition, the Company considers a reserve for doubtful 
accounts based on the credit worthiness of the customers and continually reviews and adjusts for current economic trends that 
might impact the level of future credit losses. The reserve represents management's best estimate of uncollectible amounts. As of 
December 31, 2018 and 2017, the allowance for doubtful accounts was $32 million and $28 million, respectively.

Inventory

Inventory is valued at the lower of weighted average cost or market, and consists principally of fuel oil, coal and raw materials 
used to generate electricity or steam.  The Company removes these inventories as they are used in the production of electricity or 
steam.  Spare parts inventory is valued at weighted average cost.  The Company removes these inventories when they are used 
for repairs, maintenance or capital projects.  The Company expects to recover the fuel oil, coal, raw materials, and spare parts 
costs in the ordinary course of business.   Finished goods inventory is valued at the lower of cost or net realizable value with cost 
being determined on a first-in first-out basis.  The Company removes these inventories as they are sold to customers. Sales of 
inventory are classified as an operating activity in the consolidated statements of cash flows. 

Property, Plant and Equipment

Property, plant and equipment are stated at cost or, in the case of business acquisitions, fair value; however, impairment 
adjustments are recorded whenever events or changes in circumstances indicate that their carrying values may not be recoverable. 
NRG also classifies nuclear fuel related to the Company's 44% ownership interest in STP as part of the Company's property, plant, 
and  equipment.  Significant  additions  or  improvements  extending  asset  lives  are  capitalized  as  incurred,  while  repairs  and 
maintenance that do not improve or extend the life of the respective asset are charged to expense as incurred.  Depreciation, other 
than nuclear fuel, is computed using the straight-line method, while nuclear fuel is amortized based on units of production over 
the estimated useful lives. Certain assets and their related accumulated depreciation amounts are adjusted for asset retirements 
and disposals with the resulting gain or loss included in cost of operations in the consolidated statements of operations.

Asset Impairments

Long-lived assets that are held and used are reviewed for impairment whenever events or changes in circumstances indicate 
carrying values may not be recoverable. Such reviews are performed in accordance with ASC 360. An impairment loss is indicated 
if the total future estimated undiscounted cash flows expected from an asset are less than its carrying value. An impairment charge 
is measured by the difference between an asset's carrying amount and fair value with the difference recorded in operating costs 
and expenses in the consolidated statements of operations. Fair values are determined by a variety of valuation methods, including 
third-party appraisals, sales prices of similar assets, and present value techniques.

116

 
 
 
Investments accounted for by the equity method are reviewed for impairment in accordance with ASC 323, Investments-
Equity Method and Joint Ventures, or ASC 323, which requires that a loss in value of an investment that is an other-than-temporary 
decline should be recognized. The Company identifies and measures losses in the value of equity method investments based upon 
a comparison of fair value to carrying value. For further discussion of these matters, refer to Note 9, Asset Impairments.

Development Costs and Capitalized Interest

Development  costs  include  project  development  costs,  which  are  expensed  in  the  preliminary  stages  of  a  project  and 
capitalized when the project is deemed to be commercially viable. Commercial viability is determined by one or a series of actions 
including, among others, Board of Director approval pursuant to a formal project plan that subjects the Company to significant 
future obligations that can only be discharged by the use of a Company asset. When a project is available for operations, capitalized 
interest and capitalized project development costs are reclassified to property, plant and equipment and depreciated on a straight-
line basis over the estimated useful life of the project's related assets. Capitalized costs are charged to expense if a project is 
abandoned or management otherwise determines the costs to be unrecoverable. 

Interest incurred on funds borrowed to finance capital projects is capitalized until the project under construction is ready for 
its intended use. The amount of interest capitalized for the years ended December 31, 2018, 2017, and 2016, was $7 million, $20 
million, and $29 million, respectively.

Debt Issuance Costs

Debt issuance costs are capitalized and amortized as interest expense on a basis which approximates the effective interest 
method over the term of the related debt. Debt issuance costs are presented as a direct deduction from the carrying amount of the 
related debt. 

Intangible Assets

Intangible  assets  represent  contractual  rights  held  by  the  Company.  The  Company  recognizes  specifically  identifiable 
intangible assets including customer contracts, customer relationships, energy supply contracts, marketing partnerships, power 
purchase agreements, trade names, emission allowances, and fuel contracts when specific rights and contracts are acquired. These 
intangible assets are amortized based on expected volumes, expected delivery, expected discounted future net cash flows, straight 
line or units of production basis. As of December 31, 2018 and 2017, the Company had accumulated amortization related to its 
intangible assets of $1.2 billion and $1.6 billion, respectively.

Emission allowances held-for-sale, which are included in other non-current assets on the Company's consolidated balance 
sheet, are not amortized; they are carried at the lower of cost or fair value and reviewed for impairment in accordance with ASC 
360.

Goodwill

In accordance with ASC 350, the Company recognizes goodwill for the excess cost of an acquired entity over the net value 
assigned to assets acquired and liabilities assumed.  NRG performs goodwill impairment tests annually, during the fourth quarter, 
and when events or changes in circumstances indicate that the carrying value may not be recoverable.  

The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting 
unit is less than its carrying amount. The more-likely-than-not threshold is defined as having a likelihood of more than 50 percent.  
If it is not more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, there is no goodwill impairment.

In the absence of sufficient qualitative factors, the Company performs a quantitative assessment by determining the fair value 
of the reporting unit and comparing the fair value to its book value. If the fair value of the reporting unit exceeds its book value, 
goodwill  of  the  reporting  unit  is  not  considered  impaired.  If  the  book  value  exceeds  fair  value,  the  Company  recognizes  an 
impairment loss equal to the difference between book value and fair value.

For  further  discussion  of  goodwill  and  goodwill  impairment  losses  recognized  refer  to  Note  10,  Goodwill  and  Other 

Intangibles.  

Income Taxes

The Company accounts for income taxes using the liability method in accordance with ASC 740, which requires that the 
Company use the asset and liability method of accounting for deferred income taxes and provide deferred income taxes for all 
significant temporary differences.

117

The Company has two categories of income tax expense or benefit — current and deferred, as follows:

•  Current income tax expense or benefit consists solely of current taxes payable less applicable tax credits, and

•  Deferred income tax expense or benefit is the change in the net deferred income tax asset or liability, excluding amounts 

charged or credited to accumulated other comprehensive income

The Company reports some of its revenues and expenses differently for financial statement purposes than for income tax 
return purposes, resulting in temporary and permanent differences between the Company's financial statements and income tax 
returns.  The tax effects of such temporary differences are recorded as either deferred income tax assets or deferred income tax 
liabilities in the Company's consolidated balance sheets.  The Company measures its deferred income tax assets and deferred 
income tax liabilities using income tax rates that are currently in effect. The Company believes it is more-likely-than-not that the 
results of future operations will generate sufficient taxable income which includes the future reversal of existing taxable temporary 
differences to realize deferred tax assets, net of valuation allowances. In arriving at this conclusion to utilize projections of future 
profit before tax in its estimate of future taxable income, the Company considered the profit before tax generated in recent years.  
A valuation allowance is recorded to reduce the Company's net deferred tax assets to an amount that is more-likely-than-not to be 
realized.

The Company reduces its current income tax expense in the consolidated statement of operations for any investment tax 
credits, or ITCs, that are not convertible into cash grants, as well as other tax credits, in the period the tax credit is generated.  ITCs 
that are convertible into cash grants, as well as the deferred income tax benefit generated by the difference in the financial statement 
and tax basis of the related assets, are recorded as a reduction to the carrying value of the underlying property and subsequently 
amortized to earnings on a straight-line basis over the useful life of each underlying property.

The Company accounts for uncertain tax positions in accordance with ASC 740, which applies to all tax positions related 
to income taxes.  Under ASC 740, tax benefits are recognized when it is more-likely-than-not that a tax position will be sustained 
upon examination by the authorities.  The benefit recognized from a position that has surpassed the more-likely-than-not threshold 
is the largest amount of benefit that is more than 50% likely to be realized upon settlement.  The Company recognizes interest and 
penalties accrued related to uncertain tax benefits as a component of income tax expense.

In accordance with ASC 805 and as discussed further in Note 18, Income Taxes, changes to existing net deferred tax assets 

or valuation allowances or changes to uncertain tax benefits, are recorded to income tax expense.

Revenue Recognition

Revenue from Contracts with Customers

On January 1, 2018, the Company adopted the guidance in ASC 606 using the modified retrospective method applied to 
contracts that were not completed as of the adoption date. The Company recognized the cumulative effect of initially applying the 
new standard as a credit to the opening balance of accumulated deficit, resulting in a decrease of approximately $15 million. The 
adjustment primarily related to costs incurred to obtain a contract with customers and customer incentives.  Following the adoption 
of the new standard, the Company’s revenue recognition of its contracts with customers remains materially consistent with its 
historical practice. The comparative information has not been restated and continues to be reported under the accounting standards 
in effect for those periods. The Company's policies with respect to its various revenue streams are detailed below. In general, the 
Company  applies  the  invoicing  practical  expedient  to  recognize  revenue  for  the  revenue  streams  detailed  below,  except  in 
circumstances where the invoiced amount does not represent the value transferred to the customer. 

Retail Revenues 

Gross revenues for energy sales and services to retail customers are recognized as the Company transfers the promised goods 
and services to the customer. For the majority of its electricity contracts, the Company’s performance obligation with the customer 
is satisfied over time and performance obligations for its electricity products are recognized as the customer takes possession of 
the product. The Company also allocates the contract consideration to distinct performance obligation in a contract for which the 
timing of the revenue recognized is different. Additionally, customer discounts and incentives reduce the contract consideration 
and are recognized over the term of the contract. 

 Energy sales and services that have been delivered but not billed by period end are estimated. Accrued unbilled revenues 
are based on estimates of customer usage since the date of the last meter reading provided by the independent system operators 
or electric distribution companies. Volume estimates are based on daily forecasted volumes and estimated customer usage by class. 
Unbilled  revenues  are  calculated  by  multiplying  these  volume  estimates  by  the  applicable  rate  by  customer  class.  Estimated 
amounts are adjusted when actual usage is known and billed.

118

As contracts for retail electricity can be for multi-year periods, the Company has performance obligations under these 
contracts that have not yet been satisfied. These performance obligations have transaction prices that are both fixed and variable, 
and that vary based on the contract duration, customer type, inception date and other contract-specific factors.  For the fixed price 
contracts, the amount of any unsatisfied performance obligations will vary based on customer usage, which will depend on factors 
such as weather and customer activity and therefore it is not practicable to estimate such amounts.

Energy Revenue

Both physical and financial transactions are entered into to optimize the financial performance of the Company's generating 
facilities. Electric energy revenue is recognized upon transmission to the customer over time, using the output method for measuring 
progress of satisfaction of performance obligations. Physical transactions, or the sale of generated electricity to meet supply and 
demand, are recorded on a gross basis in the Company's consolidated statements of operations. The Company applies the invoicing 
practical expedient, where applicable, in recognizing energy revenue.  Under the practical expedient, revenue is recognized based 
on the invoiced amount which is equal to the value to the customer of NRG’s performance obligation completed to date.  Financial 
transactions, or the buying and selling of energy for trading purposes, are recorded net within operating revenues in the consolidated 
statements of operations in accordance with ASC 815.

Capacity Revenue

  Capacity revenues consist of revenues billed to a third party at either the market or a negotiated contract price for making 
installed  generation  and  demand  response  capacity  available  in  order  to  satisfy  system  integrity  and  reliability  requirements. 
Capacity  revenues  are  recognized  over  time,  using  the  output  method  for  measuring  progress  of  satisfaction  of  performance 
obligations. The Company applies the invoicing practical expedient, where applicable, in recognizing capacity revenue.  Under 
the practical expedient, revenue is recognized based on the invoiced amount which is equal to the value to the customer of NRG’s 
performance obligation completed to date.

Capacity revenue contracts mainly consist of:

Capacity auctions — The Company's largest sources of capacity revenues are capacity auctions in PJM, ISO-NE, and NYISO. 
Both  ISO-NE  and  PJM  operate  a  pay-for-performance  model  where  capacity  payments  are  modified  based  on  real-time 
performance, where NRG's actual revenues will be the combination of revenues based on the cleared auction MWs plus the net 
of any over- and under-performance of NRG's fleet. In addition, MISO has an annual auction, known as the Planning Resource 
Auction, or PRA. As of December 31, 2018, estimated future revenues for cleared auction MWs in the various capacity auctions 
are $618 million, $481 million, $532 million, and $244 million for fiscal years 2019, 2020, 2021 and 2022, respectively. 

Resource adequacy and bilateral contracts — In California, there is a resource adequacy requirement that is primarily satisfied 
through bilateral contracts. Such bilateral contracts are typically short-term resource adequacy contracts. When bilateral contracting 
does not satisfy the resource adequacy need, such shortfalls can be addressed through procurement tools administered by the 
CAISO, including the capacity procurement mechanism or reliability must-run contracts. Demand payments from the current 
long-term contracts are tied to summer peak demand and provide a mechanism for recovering a portion of the costs associated 
with new or changed environmental laws or regulations. In Texas and New York, capacity and contracted revenues are through 
bilateral contracts with third parties of our Retail segment.

Renewable Energy Credits

Renewable energy credits are usually sold through long-term contracts. Revenue from the sale of self-generated RECs is 
recognized when related energy is generated and simultaneously delivered even in cases where there is a certification lag as it has 
been deemed to be perfunctory. 

In a bundled contract to sell energy, capacity and/or self-generated RECs, all performance obligations are deemed to be 
delivered at the same time and hence, timing of recognition of revenue for all performance obligations is the same and occurs over 
time.  In such cases, it is often unnecessary to allocate transaction price to multiple performance obligations.

Sale of Emission Allowances 

The Company records its inventory of emission allowances as part of intangible assets. From time to time, management may 
authorize the transfer of emission allowances in excess of expected usage from the Company's emission bank to intangible assets 
held-for-sale for trading purposes. The Company records the sale of emission allowances on a net basis within operating revenue 
in the Company's consolidated statements of operations.

Contract Amortization 

Assets and liabilities recognized through acquisitions related to the sale of electric capacity and energy in future periods for 
which the fair value has been determined to be significantly less (more) than market are amortized to revenue over the term of 
each underlying contract based on actual generation and/or contracted volumes. 

Lease Revenue

Certain of the Company’s revenues are obtained through leases of rooftop residential solar systems, which are accounted 
for as operating leases in accordance with ASC 840, Leases.  Pursuant to the lease agreements, the customers’ monthly payments 
are pre-determined fixed monthly amounts and may include an annual fixed percentage escalation to reflect the impact of utility 
rate increases over the lease term, which is 20 years.  The Company records operating lease revenue on a straight-line basis over 
the life of the lease term.  Certain customers made initial down payments that are being amortized over the life of the lease.  The 
difference between the payments received and the revenue recognized is recorded as deferred revenue.

The  Company's  customer  acquisition  costs  consist  of  broker  fees,  commission  payments  and  other  costs  that  represent 
incremental costs of obtaining the contract with customers for which the Company expects to recover. The Company amortizes 
these amounts over the estimated life of the customer contract. As a practical expedient, the Company expenses the incremental 
costs of obtaining a contract if the amortization period of the asset would have been one year or less.

When the Company receives consideration from the customer that is in excess of the amount due, such consideration is 
reclassified to deferred revenue, which represents a contract liability. Generally, the Company will recognize revenue from contract 
liabilities in the next period as the Company satisfies its performance obligations.

Lessor Accounting

Certain of the Company's revenues are obtained through PPAs or other contractual agreements.  Many of these agreements 

are accounted for as operating leases under ASC 840 Leases.

Certain of these leases have no minimum lease payments and all of the rent is recorded as contingent rent on an actual basis 
when the electricity is delivered.  Judgment is required by management in determining the economic life of each generating facility, 
in evaluating whether certain lease provisions constitute minimum payments or represent contingent rent and other factors in 
determining whether a contract contains a lease and whether the lease is an operating lease or capital lease.  Contingent rental 
income recognized in the years ended December 31, 2018, 2017, and 2016 was $104 million, $253 million, and $272 million, 
respectively.

Gross Receipts and Sales Taxes

In connection with its retail business, the Company records gross receipts taxes on a gross basis in revenues and cost of 
operations in its consolidated statements of operations.  During the years ended December 31, 2018, 2017, and 2016, the Company's 
revenues  and  cost  of  operations  included  gross  receipts  taxes  of  $99  million,  $92  million,  and  $101  million,  respectively.  
Additionally, the retail business records sales taxes collected from its taxable customers and remitted to the various governmental 
entities on a net basis; thus, there is no impact on the Company's consolidated statement of operations.

Cost of Energy for Retail Operations

The cost of energy for electricity sales and services to retail customers is included in cost of operations and is based on 
estimated supply volumes for the applicable reporting period. A portion of the cost of energy $105 million, $107 million, and $90 
million as of December 31, 2018, 2017, and 2016, respectively, was accrued and consisted of estimated transmission and distribution 
charges not yet billed by the transmission and distribution utilities. In estimating supply volumes, the Company considers the 
effects of historical customer volumes, weather factors and usage by customer class.  Transmission and distribution delivery fees 
are estimated using the same method used for electricity sales and services to retail customers.  In addition, ISO fees are estimated 
based on historical trends, estimated supply volumes and initial ERCOT ISO settlements. Volume estimates are then multiplied 
by the supply rate and recorded as cost of operations in the applicable reporting period.

121

Derivative Financial Instruments

The  Company  accounts  for  derivative  financial  instruments  under ASC  815,  which  requires  the  Company  to  record  all 
derivatives on the balance sheet at fair value unless they qualify for a NPNS exception. Changes in the fair value of non-hedge 
derivatives are immediately recognized in earnings. Changes in the fair value of derivatives accounted for as cash flow hedges, 
if elected for hedge accounting, are deferred and recorded as a component of accumulated OCI until the hedged transactions occur 
and are recognized in earnings.

The Company's primary derivative instruments are power purchase or sales contracts, fuels purchase contracts, other energy 
related commodities, and interest rate instruments used to mitigate variability in earnings due to fluctuations in market prices and 
interest rates.  On an ongoing basis, the Company assesses the effectiveness of all derivatives that are designated as hedges for 
accounting purposes in order to determine that each derivative continues to be highly effective in offsetting changes in fair values 
or cash flows of hedged items. Internal analyses that measure the statistical correlation between the derivative and the associated 
hedged item determine the effectiveness of such a contract designated as a hedge.  If it is determined that the derivative instrument 
is not highly effective as a hedge, hedge accounting will be discontinued prospectively.  In this case, the gain or loss previously 
deferred in accumulated OCI would be frozen until the underlying hedged instrument is delivered unless the transactions being 
hedged are no longer probable of occurring in which case the amount in OCI would be immediately reclassified into earnings. If 
the derivative instrument is terminated, the effective portion of this derivative deferred in accumulated OCI will be frozen until 
the underlying hedged item is delivered.

Revenues and expenses on contracts that qualify for the NPNS exception are recognized when the underlying physical 
transaction is delivered.  While these contracts are considered derivative financial instruments under ASC 815, they are not recorded 
at fair value, but on an accrual basis of accounting.  If it is determined that a transaction designated as NPNS no longer meets the 
scope exception, the fair value of the related contract is recorded on the balance sheet and immediately recognized through earnings.

NRG's trading activities are subject to limits in accordance with the Company's Risk Management Policy.  These contracts 
are recognized on the balance sheet at fair value and changes in the fair value of these derivative financial instruments are recognized 
in earnings.

Foreign Currency Translation and Transaction Gains and Losses

The local currencies are generally the functional currency of NRG's foreign operations.  Foreign currency denominated assets 
and liabilities are translated at end-of-period rates of exchange. Revenues, expenses, and cash flows are translated at the weighted-
average  rates  of  exchange  for  the  period.   The  resulting  currency  translation  adjustments  are  not  included  in  the  Company's 
consolidated statements of operations for the period, but are accumulated and reported as a separate component of stockholders' 
equity until sale or complete or substantially complete liquidation of the net investment in the foreign entity takes place.  Foreign 
currency transaction gains or losses are reported within other income/(expense) in the Company's consolidated statements of 
operations.  For the years ended December 31, 2018, 2017, and 2016, amounts recognized as foreign currency transaction gains 
(losses) were immaterial.  The Company's cumulative translation adjustment balances as of December 31, 2018, 2017, and 2016
were $(13) million, $(2) million and $(11) million, respectively.

Concentrations of Credit Risk

Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of trust funds, 
accounts receivable, notes receivable, derivatives, and investments in debt securities. Trust funds are held in accounts managed 
by experienced investment advisors. Certain accounts receivable, notes receivable, and derivative instruments are concentrated 
within entities engaged in the energy industry. These industry concentrations may impact the Company's overall exposure to credit 
risk, either positively or negatively, in that the customers may be similarly affected by changes in economic, industry or other 
conditions. Receivables and other contractual arrangements are subject to collateral requirements under the terms of enabling 
agreements. However, the Company believes that the credit risk posed by industry concentration is offset by the diversification 
and creditworthiness of its customer base. See Note 4, Fair Value of Financial Instruments, for a further discussion of derivative 
concentrations.

Fair Value of Financial Instruments

The carrying amount of cash and cash equivalents, funds deposited by counterparties, receivables, accounts payable, and 
accrued  liabilities  approximate  fair  value  because  of  the  short-term  maturity  of  these  instruments.  See  Note  4, Fair  Value  of 
Financial Instruments, for a further discussion of fair value of financial instruments.  

122

Asset Retirement Obligations

The Company accounts for AROs in accordance with ASC 410-20, Asset Retirement Obligations, or ASC 410-20.  Retirement 
obligations associated with long-lived assets included within the scope of ASC 410-20 are those for which a legal obligation exists 
under enacted laws, statutes, and written or oral contracts, including obligations arising under the doctrine of promissory estoppel, 
and for which the timing and/or method of settlement may be conditional on a future event. ASC 410-20 requires an entity to 
recognize the fair value of a liability for an ARO in the period in which it is incurred and a reasonable estimate of fair value can 
be made.

Upon initial recognition of a liability for an ARO, the Company capitalizes the asset retirement cost by increasing the carrying 
amount of the related long-lived asset by the same amount.  Over time, the liability is accreted to its future value, while the 
capitalized cost is depreciated over the useful life of the related asset. See Note 12 , Asset Retirement Obligations, for a further 
discussion of AROs.

Pensions and Other Postretirement Benefits

The  Company  offers  pension  benefits  through  a  defined  benefit  pension  plan.    In  addition,  the  Company  provides 
postretirement  health  and  welfare  benefits  for  certain  groups  of  employees.  The  Company  accounts  for  pension  and  other 
postretirement benefits in accordance with ASC 715, Compensation — Retirement Benefits.  The Company recognizes the funded 
status of the Company's defined benefit plans in the statement of financial position and records an offset for gains and losses as 
well as all prior service costs that have not been included as part of the Company's net periodic benefit cost to other comprehensive 
income.  The determination of the Company's obligation and expenses for pension benefits is dependent on the selection of certain 
assumptions.  These assumptions determined by management include the discount rate, the expected rate of return on plan assets 
and the rate of future compensation increases. The Company's actuarial consultants assist in determining assumptions for such 
items as retirement age.  The assumptions used may differ materially from actual results, which may result in a significant impact 
to the amount of pension obligation or expense recorded by the Company.

The Company measures the fair value of its pension assets in accordance with ASC 820, Fair Value Measurements and 

Disclosures, or ASC 820.

Stock-Based Compensation

The  Company  accounts  for  its  stock-based  compensation  in  accordance  with  ASC 718,  Compensation —  Stock 
Compensation, or ASC 718.  The fair value of the Company's non-qualified stock options and market stock units are estimated 
on the date of grant using the Black-Scholes option-pricing model and the Monte Carlo valuation model, respectively.  NRG uses 
the Company's common stock price on the date of grant as the fair value of the Company's restricted stock units and deferred stock 
units.  Forfeiture rates are estimated based on an analysis of the Company's historical forfeitures, employment turnover, and 
expected future behavior.  The Company recognizes compensation expense for both graded and cliff vesting awards on a straight-
line basis over the requisite service period for the entire award.

Investments Accounted for by the Equity Method

The Company has investments in various domestic energy projects, as well as one Australian project.  The equity method 
of accounting is applied to such investments in affiliates, which include joint ventures and partnerships, because the ownership 
structure prevents the Company from exercising a controlling influence over the operating and financial policies of the projects.  
Under this method, equity in pre-tax income or losses of domestic partnerships and, generally, in the net income or losses of its 
Australian project, are reflected as equity in earnings of unconsolidated affiliates. Distributions from equity method investments 
that represent earnings on the Company's investment are included within cash flows from operating activities and distributions 
from equity method investments that represent a return of the Company's investment are included within cash flows from investing 
activities. 

123

Tax Equity Arrangements

The  Company’s  redeemable  noncontrolling  interest  in  subsidiaries  and  certain  amounts  within  noncontrolling  interest, 
included in stockholders' equity, represent third-party interests in the net assets under certain tax equity arrangements, which are 
consolidated by the Company, that have been entered into to finance the cost of solar energy systems under operating leases and 
wind facilities eligible for certain tax credits.  The Company has determined that the provisions in the contractual agreements of 
these structures represent substantive profit sharing arrangements.  Further, the Company has determined that the appropriate 
methodology for calculating the noncontrolling interest and redeemable noncontrolling interest that reflects the substantive profit 
sharing arrangements is a balance sheet approach utilizing the HLBV method.  Under the HLBV method, the amounts reported 
as noncontrolling interest and redeemable noncontrolling interests represent the amounts the investors that are party to the tax 
equity arrangements would hypothetically receive at each balance sheet date under the liquidation provisions of the contractual 
agreements, assuming the net assets of the funding structures were liquidated at their recorded amounts determined in accordance 
with GAAP.  The investors’ interests in the results of operations of the funding structures are determined as the difference in 
noncontrolling interest and redeemable noncontrolling interests at the start and end of each reporting period, after taking into 
account any capital transactions between the structures and the funds’ investors.  The calculations utilized to apply the HLBV 
method include estimated calculations of taxable income or losses for each reporting period.  

Redeemable Noncontrolling Interest

To the extent that the third-party has the right to redeem their interests for cash or other assets, the Company has included 
the noncontrolling interest attributable to the third party as a component of temporary equity in the mezzanine section of the 
consolidated balance sheet. The following table reflects the changes in the Company's redeemable noncontrolling interest balance 
for the years ended December 31, 2018, 2017, and 2016.

Sale-Leaseback Arrangements 

NRG is party to sale-leaseback arrangements that provide for the sale of certain assets to a third party and simultaneous 
leaseback to the Company.  In accordance with ASC 840-40, Sale-Leaseback Transactions, if the seller-lessee retains, through the 
leaseback, substantially all of the benefits and risks incident to the ownership of the property sold, the sale-leaseback transaction 
is accounted for as a financing arrangement.  An example of this type of continuing involvement would include an option to 
repurchase the assets or the buyer-lessor having the option to sell the assets back to the Company.  This provision is included in 
most of the Company’s sale-leaseback arrangements.  As such, the Company accounts for these arrangements as financings.

124

Under the financing method, the Company does not recognize as income any of the sale proceeds received from the lessor 
that contractually constitutes payment to acquire the assets subject to these arrangements.  Instead, the sale proceeds received are 
accounted for as financing obligations and leaseback payments made by the Company are allocated between interest expense and 
as a reduction to the financing obligation.  Interest on the financing obligation is calculated using the Company’s incremental 
borrowing rate at the inception of the arrangement on the outstanding financing obligation.  Judgment is required to determine 
the appropriate borrowing rate for the arrangement and in determining any gain or loss on the transaction that would be recorded 
either at the end of or over the lease term.

As described in Note 3, Acquisitions, Discontinued Operations and Dispositions, the Company entered into an agreement 
to leaseback the Cottonwood facility upon the close of the South Central Portfolio transaction. The lease will be accounted for as 
an operating lease and accordingly, a right of use asset and lease liability will be set up on the lease commencement date which 
will be amortized through the end of the lease.

Marketing and Advertising Costs 

The Company expenses its marketing and advertising costs as incurred and which are included within selling, general and 
administrative  expenses. The  costs  of  tangible  assets  used  in  advertising  campaigns  are  recorded  as  fixed  assets  or  deferred 
advertising costs and amortized as advertising costs over the shorter of the useful life of the asset or the advertising campaign.  
The Company has several long-term sponsorship arrangements.  Payments related to these arrangements are deferred and expensed 
over the term of the arrangement.  Advertising expenses for the years ended December 31, 2018, 2017, and 2016 were $73 million, 
$66 million, and $79 million, respectively. 

Reorganization Costs

Reorganization costs include costs incurred by the Company related to the Transformation Plan implementation and primarily 
reflect severance and contract modifications. As of December 31, 2018 and December 31, 2017, $90 million and $44 million were 
incurred.

Business Combinations

The Company accounts for its business combinations in accordance with ASC 805, Business Combinations, or ASC 805. 
ASC 805 requires an acquirer to recognize and measure in its financial statements the identifiable assets acquired, the liabilities 
assumed, and any noncontrolling interest in the acquiree at fair value at the acquisition date.  It also recognizes and measures the 
goodwill acquired or a gain from a bargain purchase in the business combination and determines what information to disclose to 
enable users of an entity's financial statements to evaluate the nature and financial effects of the business combination.  In addition, 
transaction costs are expensed as incurred.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of 
the financial statements, 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 these estimates. 

In recording transactions and balances resulting from business operations, the Company uses estimates based on the best 
information available. Estimates are used for such items as plant depreciable lives, tax provisions, uncollectible accounts, actuarially 
determined benefit costs, the valuation of energy commodity contracts, environmental liabilities, legal costs incurred in connection 
with recorded loss contingencies, and assets acquired and liabilities assumed in business combinations, among others.  In addition, 
estimates are used to test long-lived assets and goodwill for impairment and to determine the fair value of impaired assets.  As 
better  information  becomes  available  or  actual  amounts  are  determinable,  the  recorded  estimates  are  revised.    Consequently, 
operating results can be affected by revisions to prior accounting estimates.

Reclassifications

Certain prior year amounts have been reclassified for comparative purposes. The reclassifications did not affect results from 

operations, net assets or cash flows.

Recent Accounting Developments - Guidance Adopted in 2018

ASU  2017-07  —  In  March  2017,  the  FASB  issued ASU  No.  2017-07,  Compensation  -  Retirement  Benefits  (Topic  715), 

Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, or ASU No. 2017-07.    
Previous GAAP does not indicate where the amount of net benefit cost should be presented in an entity’s income statement and 
does not require entities to disclose the amount of net benefit cost that is included in the income statement. The amendments of 
ASU  No.  2017-07  require  an  entity  to  report  the  service  cost  component  of  net  benefit  costs  in  the  same  line  item  as  other 
compensation  costs  arising  from  services  rendered  by  the  related  employees  during  the  applicable  service  period. The  other 
components of net benefit cost are required to be presented separately from the service cost component and outside the subtotal 
of income from operations. Further, ASU No. 2017-07 prescribes that only the service cost component of net benefit costs is 
eligible for capitalization. The Company adopted the amendments of ASU No. 2017-07 effective January 1, 2018. The adoption 
of ASU No. 2017-07 did not have a material impact on the Company's results of operations, cash flows, and statement of financial 
position.

ASU 2016-01 - In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): 
Recognition and Measurement of Financial Assets and Financial Liabilities, or ASU No. 2016-01. The amendments of ASU No. 
2016-01  eliminate  available-for-sale  classification  of  equity  investments  and  require  that  equity  investments  (except  those 
accounted for under the equity method of accounting, or those that result in consolidation of the investee) be generally measured 
at fair value with changes in fair value recognized in net income. Further, the amendments require that financial assets and financial 
liabilities be presented separately in the notes to the financial statements, grouped by measurement category and form of financial 
asset. The guidance in ASU No. 2016-01 is effective for financial statements issued for fiscal years beginning after December 15, 
2017, and interim periods within those annual periods. The Company adopted the amendments of ASU No. 2016-01 effective 
January 1, 2018.  In connection with the adoption of the standard, the Company has applied the guidance on a modified retrospective 
basis, which resulted in no material adjustments recorded to the consolidated results of operations, cash flows, and statement of 
financial position.

ASU 2014-09 — In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), or 
Topic 606, which was further amended through various updates issued by the FASB thereafter. The amendments of Topic 606 
completed the joint effort between the FASB and the IASB, to develop a common revenue standard for GAAP and IFRS, and to 
improve financial reporting. The guidance under Topic 606 provides that an entity should recognize revenue to depict the transfer 
of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in 
exchange for the goods or services provided and establishes a five-step model to be applied by an entity in evaluating its contracts 
with customers. The Company has also elected the practical expedient available under Topic 606 for measuring progress toward 
complete satisfaction of a performance obligation and for disclosure requirements of remaining performance obligations. The 
practical expedient allows an entity to recognize revenue in the amount to which the entity has the right to invoice such that the 
entity has a right to the consideration in an amount that corresponds directly with the value to the customer for performance 
completed to date by the entity. The Company adopted the standard effective January 1, 2018. The adoption of Topic 606 at the 
date of initial application, as prescribed under the modified retrospective transition method, did not have a material impact on the 
Company's financial statements. The adoption of Topic 606 also includes additional disclosure requirements beginning in the first 
quarter of 2018. Many of these disclosures are not substantially different than the Company's existing disclosures. Topic 606 
requires disclosure of disaggregated revenue amounts, which the Company has been disclosing since the date of adoption. 

Recent Accounting Developments - Guidance Not Yet Adopted  

ASU 2018-17 - In October 2018, the FASB issued ASU No. 2018-17, Consolidations (Topic 810): Targeted Improvements to 
Related Party Guidance for Variable Interest Entities, in response to stakeholders’ observations that Topic 810, Consolidations, 
could be improved thereby improving general purpose financial reporting.  Specifically, ASC 2018-17 requires application of the 
variable interest entity (VIE) guidance to private companies under common control and consideration of indirect interest held 
through related parties under common control for determining whether fees paid to decision makers and service providers are 
variable interests.  The amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within 
those fiscal years. All entities are required to apply the amendments retrospectively with a cumulative-effect adjustment to retained 
earnings at the beginning of the earliest period presented. The Company is evaluating the impact of adopting this guidance on the 
consolidated financial statements and disclosures.

ASU 2018-13 - In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure 
Framework - Changes to the Disclosure Requirement for Fair value Measurement), or ASU No. 2018-13. The guidance in ASU 
No. 2018-13 eliminates such disclosures as the amount of and reasons for transfers between Level 1 and Level 2 of the fair 
value hierarchy. The amendments in ASU No. 2018-13 add new disclosure requirements for Level 3 measurements. ASU No. 
2018-13 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with 
early adoption permitted for any eliminated or modified disclosures. Certain disclosures in ASU No. 2018-13 are required to be 

126

applied on a retrospective basis and others on a prospective basis. As the amendment contemplates changes in disclosures only, 
it will have no material impact on the Company's results of operations, cash flows, or statement of financial position.

ASU 2016-02 - In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), or Topic 842, with the 

objective to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on 
the balance sheet and to improve financial reporting by expanding the related disclosures. The guidance in Topic 842 provides 
that a lessee that may have previously accounted for a lease as an operating lease under current GAAP should recognize the 
assets and liabilities that arise from a lease on the balance sheet. In addition, Topic 842 expands the required quantitative and 
qualitative disclosures with regards to lease arrangements. The Company adopted the standard and its subsequent 
corresponding updates effective January 1, 2019 under the modified retrospective approach by applying the provisions of the 
new leases guidance at the effective date without adjusting the comparative periods presented. The Company has assessed its 
leasing arrangements and  evaluated the impact of applying practical expedients and accounting policy elections. The Company 
implemented lease accounting software to meet the reporting requirements of the standard and identified changes to its business 
processes and controls to support recognition and disclosure under the new standard. Management estimates operating lease 
liabilities will increase between $380 million and $420 million and right-of-use assets between $300 million and $340 million 
will be established upon adoption, before considering deferred taxes.  Management does not believe the adoption of Topic 842 
will have a material impact on the statements of operations or cash flows.

XOOM Energy Acquisition — On June 1, 2018, the Company completed the acquisition of XOOM Energy, LLC, an electricity 
and natural gas retailer operating in 19 states, Washington, D.C. and Canada, for approximately $213 million in cash. The acquisition 
increased NRG's retail portfolio by approximately 300,000 customers.  The purchase price was allocated as follows:

Discontinued Operations

Sale of South Central Portfolio

  On February 4, 2019, the Company completed the sale of its South Central Portfolio to Cleco. The Company concluded 
that the divested business met the criteria for discontinued operations, as the disposition represents a strategic shift in the business 
in which NRG operates and held-for-sale criteria as of December 31, 2018.  As such, all prior period results for the operations of 
the South Central Portfolio have been reclassified as discontinued operations. In connection with the transaction, NRG also entered 
into a transition services agreement to provide certain corporate services to the divested business.

The South Central Portfolio includes the 1,263 MW Cottonwood natural gas generating facility.  Upon the closing of the 
sale of the South Central Portfolio, NRG entered into a lease agreement with Cleco to leaseback the Cottonwood facility through 
2025.  Due to its continuing involvement with the Cottonwood facility, NRG will not use held-for-sale or discontinued operations 
treatment in accounting for historical and ongoing activity with Cottonwood.

Sale of Ownership in NRG Yield, Inc. and its Renewables Platform

On August 31, 2018, the Company completed the sale of its ownership interests in NRG Yield, Inc. and its Renewables 
Platform to GIP for total cash consideration of $1.348 billion.  The Company concluded that the divested businesses met the criteria 
for discontinued operations, as the dispositions represented a strategic shift in the business in which NRG operates.  As such, all 
prior period results for the transaction have been reclassified as discontinued operations. In connection with the transaction, NRG 
entered into a transition services agreement to provide certain corporate services to the divested businesses.

As a result of the sale of NRG Yield, Inc., the Company's indirect ownership interest in the Agua Caliente solar project was 
reduced from 51% to 35%.  As such, the Company no longer controls the project; and accordingly, no longer consolidates the 
project for financial reporting purposes.  The Company recorded its ownership interest as an equity method investment upon 
deconsolidation resulting in a gain of $8 million.   

As part of the agreement to sell NRG Yield and the Renewables Platform, the Company agreed to indemnify NRG Yield for 
any increase in property taxes for certain solar properties. The indemnity term will expire at various dates between 2029 and 2039. 
NRG has determined that the payment of this indemnity is probable and has recorded the estimated present value of the obligation 
as of the closing date of the transaction of $153 million to other non-current liabilities with a corresponding loss from discontinued 
operations. In addition to the California property tax indemnity, there were additional commitments and advisory fees totaling 
approximately $50 million. The Company will also retain all costs associated with the development and ownership of the Patriot 
Wind project until its sale to a third party pursuant to a sale agreement.  

128

   
Carlsbad

On February 6, 2018, NRG entered into an agreement with NRG Yield and GIP to sell 100% of the membership interests in 
Carlsbad Energy Holdings LLC, which owned the Carlsbad project, for $387 million of cash consideration, excluding working 
capital adjustments. The primary condition to close the Carlsbad transaction was the completion of the sale of NRG Yield and the 
Renewables Platform. As the sale of NRG Yield and the Renewables Platform has closed, the Company concluded that the Carlsbad 
project met the criteria for discontinued operations and accordingly, the financial information for all current and historical periods 
has been recast to reflect Carlsbad as a discontinued operation. The Company continued to consolidate Carlsbad for financial 
reporting purposes until the transaction  closed on February 27, 2019. Carlsbad will continue to have a ground lease and easement 
agreement with NRG. The agreement has an initial term ending in 2039 with two ten year extensions. As a result of the transaction, 
additional commitments related to the project totaled $23 million.

Summarized results of NRG Yield, Inc. and Renewables Platform and Carlsbad discontinued operations were as follows:

Sale of Assets to NRG Yield, Inc. Prior to Discontinued Operations

On June 19, 2018, the Company completed the UPMC Thermal Project and received cash consideration from NRG Yield of 

$84 million plus an additional $3 million received at final completion in January 2019.

On March 30, 2018, as part of the Transformation Plan, the Company sold to NRG Yield, Inc. 100% of NRG's interests in 
Buckthorn Renewables, LLC, which owns a 154 MW construction-stage utility-scale solar generation project, located in Texas.  
NRG Yield, Inc. paid cash consideration of approximately $42 million, excluding working capital adjustments, and assumed non-
recourse debt of approximately $183 million. 

On March 27, 2017, the Company sold to NRG Yield, Inc.: (i) a 16% interest in the Agua Caliente solar project, representing 
ownership of approximately 46 net MW of capacity and (ii) NRG's interests in seven utility-scale solar projects located in Utah 
representing 265 net MW of capacity, which have reached commercial operations. NRG Yield, Inc. paid cash consideration of 
$130 million, plus $1 million in working capital adjustments, and assumed non-recourse debt of approximately $328 million.

On September 1, 2016, the Company completed the sale of its remaining 51.05% interest in the CVSR project to NRG Yield, 
Inc. for total cash consideration of $78.5 million, plus an immaterial working capital adjustment. In addition, NRG Yield, Inc. 
assumed non-recourse project level debt of $496 million.

GenOn 

On June 14, 2017, the GenOn Entities filed voluntary petitions for relief under Chapter 11 of the Bankruptcy Code in the 
Bankruptcy Court. As a result of the bankruptcy filings, NRG concluded that it no longer controlled GenOn as it was subject to 
the control of the Bankruptcy Court; and, accordingly, NRG deconsolidated GenOn and its subsidiaries for financial reporting 
purposes as of such date.

By eliminating a large portion of its operations in the PJM market with the deconsolidation of GenOn, NRG concluded that 
GenOn met the criteria for discontinued operations, as this represented a strategic shift in the business in which NRG operated. 
As such, all prior period results for GenOn have been reclassified as discontinued operations.

Effective  July  16,  2018,  NRG  and  GenOn  consummated  the  GenOn  Settlement  whereby  the  Company  paid  GenOn 
approximately $125 million, which included (i) the settlement consideration of $261 million, (ii) the transition services credit of 
$28 million and (iii) the return of $15 million of collateral posted to NRG; offset by the (i) $151 million in borrowings under the 
intercompany secured revolving credit facility, (ii) related accrued interest and fees of $12 million, (iii) remaining payments due 
under the transition services agreement of $10 million, (iv) $4 million reduction of the settlement payment related to NRG assigning 
to GenOn approximately $8 million of historical claims against REMA and (v) certain other balances due to NRG totaling $2 
million.

GenOn's plan of reorganization was confirmed on December 14, 2018.  Pursuant to the confirmed plan, NRG retained the 
pension liability for GenOn employees for service provided prior to the completion of the reorganization. NRG also retained the 
liability for GenOn's post-employment and retiree health and welfare benefits. These liabilities were recorded within other non-
current liabilities as of December 31, 2018 and 2017. As a result of GenOn's emergence from bankruptcy, NRG is taking a deduction 
for GenOn tax losses of $9.5 billion, including a worthless stock deduction. 

Other than those obligations which survive or are independent of the releases described herein, the GenOn Settlement and 

the GenOn Chapter 11 plan provide NRG releases from GenOn and each of its debtor and non-debtor subsidiaries.

REMA Plan of Reorganization

On October 16, 2018, REMA and its subsidiaries filed voluntary petitions for chapter 11 relief and a prepackaged plan of 
reorganization in the United States Bankruptcy Court for the Southern District of Texas. The REMA debtors' plan of reorganization 
has  been  formally  accepted  by  REMA's  voting  creditors  and  is  consistent  with  the  releases  NRG  received  under  the  GenOn 
Settlement and the GenOn plan.

131

GenMA Settlement

The Bankruptcy Court order confirming the plan of reorganization also approved the settlement terms agreed to among the 
GenOn Entities, NRG, the Consenting Holders, GenOn Mid-Atlantic, and certain of GenOn Mid-Atlantic’s stakeholders, or the 
GenMA Settlement, and directed the settlement parties to cooperate in good faith to negotiate definitive documentation consistent 
with the GenMA Settlement term sheet in order to pursue consummation of the GenMA Settlement. The definitive documentation 
effectuating the GenMA Settlement was finalized and effective as of April 27, 2018. Certain terms of the compromise with respect 
to NRG and GenOn Mid-Atlantic are as follows:

Settlement of all pending litigation and objections to the Plan (including with respect to releases and feasibility);

• 
•  NRG provided $38 million in letters of credit as new qualifying credit support to GenOn Mid-Atlantic; and
•  NRG paid approximately $6 million as reimbursement of professional fees incurred by certain of GenOn Mid-Atlantic's 

stakeholders in connection with the GenMA Settlement.

Planned Dispositions

On November 1, 2018, the Company offered to Clearway Energy, Inc. its ownership interest in Agua Caliente Borrower 1, 
LLC, for approximately $120 million, which owns a 35% interest in Agua Caliente, a 290 MW utility-scale solar project located 
in Dateland, Arizona. The offer expired on January 31, 2019, with no action taken by Clearway Energy, Inc. As a result, the right 
of first offer agreement with Clearway Energy, Inc. has expired and NRG's interest in Agua Caliente is no longer subject to a right 
of first offer thereunder.

Dispositions

On August 1, 2018, the Company completed the sale of 100% of its ownership interests in BETM to Diamond Energy Trading 
and Marketing, LLC for $71 million, net of working capital adjustments, which resulted in a gain of $15 million on the sale. The 
sale also resulted in the release and return of approximately $119 million of letters of credit, $32 million of parent guarantees, and 
$4 million of net cash collateral to NRG.

On June 29, 2018, the Company completed the sale of Canal 3 to Stonepeak Kestrel for cash proceeds of approximately 

$16 million and recorded a gain of $17 million.  Prior to the sale, Canal 3 entered into a financing arrangement and received 
cash proceeds of $167 million, of which $151 million was distributed to the Company.  The related debt was non-recourse to 
NRG and was transferred to Stonepeak Kestrel in connection with the sale of Canal 3. 

In addition, the Company completed other asset sales for $28 million of cash proceeds during the year ended December 

31, 2018.

2016 Dispositions

Disposition of Majority Interest in EVgo

On June 17, 2016, the Company completed the sale of a majority interest in its EVgo business to Vision Ridge Partners for 
total consideration of approximately $39 million, including $17 million in cash received, which is net of $3 million in working 
capital adjustments, $15 million contributed as capital to the EVgo business and $7 million of future contributions by Vision Ridge 
Partners, all of which were determined based on forecasted cash requirements to operate the business in future periods.  In addition, 
the Company has future earnout potential of up to $70 million based on future profitability targets. NRG retained its original 
financial obligation of $103 million under its agreement with the CPUC whereby EVgo will build at least 200 public fast charging 
Freedom Station sites and perform the associated work to prepare 10,000 commercial and multi-family parking spaces for electric 
vehicle charging in California. As part of the sale, NRG has contracted with EVgo to continue to build the remaining required 
Freedom Stations and commercial and multi-family parking spaces for electric vehicle charging required under this obligation and 
EVgo will be directly reimbursed by NRG for the costs. As a result of the sale, the Company recorded a loss on sale of $78 million
during the second quarter of 2016, which reflects the loss on the sale of the equity interest of $27 million and the accrual of NRG's 
remaining obligation under its agreement with the CPUC of $56 million, of which $6 million remains as of December 31, 2018.  
On February 22, 2017, the Company and CPUC entered into a second amendment to the agreement which extended the operating 
period commitment for the Freedom Stations to December 5, 2020. The Company's remaining 23.7% interest in EVgo is accounted 
for as an equity method investment.  

132

Rockford Disposition

On May 12, 2016, the Company entered into an agreement with RA Generation, LLC to sell 100% of its interests in the 
Rockford I and Rockford II generating stations, or Rockford, for cash consideration of $55 million, subject to adjustments for 
working capital and the results of the PJM 2019/2020 base residual auction.  Rockford is a 450 MW natural gas facility located 
in Rockford, Illinois. The transaction triggered an indicator of impairment as the sales price was less than the carrying amount of 
the assets and, as a result, the assets were considered to be impaired.  The Company measured the impairment loss as the difference 
between the carrying amount of the assets and the agreed-upon sales price.  The Company recorded an impairment loss of $17 
million during the quarter ended June 30, 2016 to reduce the carrying amount of the assets held for sale to the fair market value.  
On July 12, 2016, the Company completed the sale of Rockford for cash proceeds of $56 million, including $1 million in adjustments 
for the PJM base residual auction results.  For further discussion on this impairment, refer to Note 9, Asset Impairments.

Note 4 — Fair Value of Financial Instruments 

For cash and cash equivalents, funds deposited by counterparties, accounts and other receivables, accounts payable, restricted 
cash, and cash collateral posted and received in support of energy risk management activities, the carrying amount approximates 
fair value because of the short-term maturity of those instruments and are classified as Level 1 within the fair value hierarchy. 

The estimated carrying values and fair values of the Company's recorded financial instruments not carried at fair market 

value are as follows:

The fair value of the Company's publicly-traded long-term debt is based on quoted market prices and is classified as Level 
2 within the fair value hierarchy.  The fair value of debt securities, non-publicly traded long-term debt, and certain notes receivable 
of the Company are based on expected future cash flows discounted at market interest rates or current interest rates for similar 
instruments with equivalent credit quality and are classified as Level 3 within the fair value hierarchy. The following table presents

Fair Value Accounting under ASC 820

ASC 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into 

three levels as follows:

•  Level 1 — quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability 
to access as of the measurement date. NRG's financial assets and liabilities utilizing Level 1 inputs include active exchange-
traded securities, energy derivatives, and trust fund investments.

•  Level 2 — inputs other than quoted prices included within Level 1 that are directly observable for the asset or liability 
or indirectly observable through corroboration with observable market data. NRG's financial assets and liabilities utilizing 
Level 2 inputs include fixed income securities, exchange-based derivatives, and over the counter derivatives such as 
swaps, options and forward contracts.

•  Level 3 — unobservable inputs for the asset or liability only used when there is little, if any, market activity for the asset 
or liability at the measurement date. NRG's financial assets and liabilities utilizing Level 3 inputs include infrequently-
traded, non-exchange-based derivatives and commingled investment funds, and are measured using present value pricing 
models.

In accordance with ASC 820, the Company determines the level in the fair value hierarchy within which each fair value 

measurement in its entirety falls, based on the lowest level input that is significant to the fair value measurement in its entirety.

Recurring Fair Value Measurements

Debt securities, equity securities, and trust fund investments, which are comprised of various U.S. debt and equity securities, 

and derivative assets and liabilities, are carried at fair market value.

Non-derivative fair value measurements

NRG's investments in debt securities are classified as Level 3 and consist of non-traded debt instruments that are valued 

based on third-party market value assessments.

The trust fund investments are held primarily to satisfy NRG's nuclear decommissioning obligations.  These trust fund 
investments hold debt and equity securities directly and equity securities indirectly through commingled funds.  The fair values 
of equity securities held directly by the trust funds are based on quoted prices in active markets and are categorized in Level 1.  
In addition, U.S. government and federal agency obligations are categorized as Level 1 because they trade in a highly liquid and 
transparent market.  The fair values of corporate debt securities are based on evaluated prices that reflect observable market 
information, such as actual trade information of similar securities, adjusted for observable differences and are categorized in 
Level 2.  Certain equity securities, classified as commingled funds, are analogous to mutual funds, are maintained by investment 
companies, and hold certain investments in accordance with a stated set of fund objectives.  The fair value of the equity securities 
classified as commingled funds are based on net asset values per fund share (the unit of account), derived from the quoted prices 
in active markets of the underlying equity securities.  However, because the shares in the commingled funds are not publicly 
quoted, not traded in an active market and are subject to certain restrictions regarding their purchase and sale, the commingled 
funds are categorized in Level 3.  See also Note 6, Nuclear Decommissioning Trust Fund.

Derivative fair value measurements

A portion of the Company's contracts are exchange-traded contracts with readily available quoted market prices.  A majority 
of NRG's contracts are non-exchange-traded contracts valued using prices provided by external sources, primarily price quotations 
available through brokers or over-the-counter and on-line exchanges.  For the majority of NRG markets, the Company receives 
quotes from multiple sources.  To the extent that NRG receives multiple quotes, the Company's prices reflect the average of the 
bid-ask mid-point prices obtained from all sources that NRG believes provide the most liquid market for the commodity. If the 
Company receives one quote, then the mid-point of the bid-ask spread for that quote is used.  The terms for which such price 
information is available vary by commodity, region and product.  A significant portion of the fair value of the Company's derivative 
portfolio is based on price quotes from brokers in active markets who regularly facilitate those transactions and the Company 
believes such price quotes are executable.  The Company does not use third party sources that derive price based on proprietary 
models or market surveys.  The remainder of the assets and liabilities represents contracts for which external sources or observable 
market quotes are not available. These contracts are valued based on various valuation techniques including but not limited to 
internal  models  based  on  a  fundamental  analysis  of  the  market  and  extrapolation  of  observable  market  data  with  similar 
characteristics.  Contracts valued with prices provided by models and other valuation techniques make up 10% of derivative assets 
and 9% of derivative liabilities.  The fair value of each contract is discounted using a risk free interest rate.  In addition, the 
Company applies a credit reserve to reflect credit risk, which for interest rate swaps is calculated utilizing the bilateral method 

136

 
 
 
 
based on published default probabilities.  For commodities, to the extent that NRG's net exposure under a specific master agreement 
is an asset, the Company uses the counterparty's default swap rate.  If the exposure under a specific master agreement is a liability, 
the Company uses NRG's default swap rate.  For interest rate swaps and commodities, the credit reserve is added to the discounted 
fair value to reflect the exit price that a market participant would be willing to receive to assume NRG's liabilities or that a market 
participant would be willing to pay for NRG's assets.  As of December 31, 2018  and December 31, 2017 the credit reserve did 
not result in a significant change in fair value.

The fair values in each category reflect the level of forward prices and volatility factors as of December 31, 2018, and may 
change as a result of changes in these factors. Management uses its best estimates to determine the fair value of commodity and 
derivative contracts NRG holds and sells. These estimates consider various factors including closing exchange and over-the-
counter price quotations, time value, volatility factors and credit exposure. It is possible, however, that future market prices could 
vary from those used in recording assets and liabilities from energy marketing and trading activities and such variations could be 
material.

NRG's significant positions classified as Level 3 include physical and financial power executed in illiquid markets as well 
as financial transmission rights, or FTRs. The significant unobservable inputs used in developing fair value include illiquid power 
location pricing which is derived as a basis to liquid locations. The basis spread is based on observable market data when available 
or derived from historic prices and forward market prices from similar observable markets when not available. For FTRs, NRG 
uses the most recent auction prices to derive the fair value. 

The following tables quantify the significant unobservable inputs used in developing the fair value of the Company's Level 

3 positions as of December 31, 2018 and 2017:

Under the guidance of ASC 815, entities may choose to offset cash collateral posted or received against the fair value of 
derivative positions executed with the same counterparties under the same master netting agreements.  The Company has chosen 
not to offset positions as defined in ASC 815.  As of December 31, 2018, the Company recorded $287 million of cash collateral 
posted and $33 million of cash collateral received on its balance sheet.

In addition to the credit risk discussion as disclosed in Note 2, Summary of Significant Accounting Policies, the following 
item is a discussion of the concentration of credit risk for the Company's financial instruments. Credit risk relates to the risk of 
loss resulting from non-performance or non-payment by counterparties pursuant to the terms of their contractual obligations.  The 
Company monitors and manages credit risk through credit policies that include: (i) an established credit approval process; (ii) a 
daily monitoring of counterparties' credit limits; (iii) the use of credit mitigation measures such as margin, collateral, prepayment 
arrangements, or volumetric limits; (iv) the use of payment netting agreements; and (v) the use of master netting agreements that 
allow for the netting of positive and negative exposures of various contracts associated with a single counterparty. Risks surrounding 
counterparty performance and credit could ultimately impact the amount and timing of expected cash flows. The Company seeks 
to mitigate counterparty risk by having a diversified portfolio of counterparties. The Company also has credit protection within 
various agreements to call on additional collateral support if and when necessary. Cash margin is collected and held at the Company 
to cover the credit risk of the counterparty until positions settle.

Counterparty Credit Risk

As  of  December 31,  2018,  counterparty  credit  exposure,  excluding  credit  exposure  from  RTOs,  ISOs,  and  registered 
commodity exchanges and certain long-term agreements, was $301 million and NRG held collateral (cash and letters of credit) 
against those positions of $123 million, resulting in a net exposure of $180 million. Approximately 66% of the Company's exposure 
before collateral is expected to roll off by the end of 2020. Counterparty credit exposure is valued through observable market 
quotes and discounted at a risk free interest rate.  The following tables highlight net counterparty credit exposure by industry sector 
and by counterparty credit quality.  Net counterparty credit exposure is defined as the aggregate net asset position for NRG with 
counterparties where netting is permitted under the enabling agreement and includes all cash flow, mark-to-market and NPNS, 
and non-derivative transactions.  The exposure is shown net of collateral held, and includes amounts net of receivables or payables.

(a)  Counterparty credit exposure excludes uranium and coal transportation contracts because of the unavailability of market prices.
(b)  The figures in the tables above exclude potential counterparty credit exposure related to RTOs, ISOs, registered commodity exchanges and certain long 

term contracts.

The Company currently has no exposure to any individual wholesale counterparty in excess of 10% of the total net exposure 
discussed above as of December 31, 2018.  Changes in hedge positions and market prices will affect credit exposure and counterparty 
concentration. Given the credit quality, diversification and term of the exposure in the portfolio, NRG does not anticipate a material 
impact on the Company's financial position or results of operations from nonperformance by any of NRG's counterparties.

138

RTOs and ISOs

The Company participates in the organized markets of CAISO, ERCOT, ISO-NE, MISO, NYISO and PJM, known as RTOs 
or ISOs. Trading in these markets is approved by FERC, or in the case of ERCOT, approved by the PUCT and includes credit 
policies that, under certain circumstances, require that losses arising from the default of one member on spot market transactions 
be shared by the remaining participants. As a result, the counterparty credit risk to these markets is limited to NRG’s share of 
overall market and are excluded from the above exposures.

Exchange Traded Transactions 

The Company enters into commodity transactions on registered exchanges, notably ICE and NYMEX. These clearinghouses 
act as the counterparty and transactions are subject to extensive collateral and margining requirements. As a result, these commodity 
transactions have limited counterparty credit risk.

Long Term Contracts

Counterparty credit exposure described above excludes credit risk exposure under certain long term contracts, including 
California tolling agreements and solar PPAs.  As external sources or observable market quotes are not available to estimate such 
exposure, the Company values these contracts based on various techniques including, but not limited to, internal models based 
on a fundamental analysis of the market and extrapolation of observable market data with similar characteristics.  Based on these 
valuation techniques, as of December 31, 2018, aggregate credit risk exposure managed by NRG to these counterparties was 
approximately $434 million for the next five years.  This amount excludes potential credit exposures for projects with long-term 
PPAs that have not reached commercial operations and any exposure for entities classified as a discontinued operation. 

NRG through its unconsolidated affiliates Ivanpah and Agua Caliente has exposure to PG&E of approximately $321 million 
for the next five years. As a result of the bankruptcy filing by PG&E on January 29, 2019, it is uncertain whether and to what 
extent the bankruptcy may have on these contracts. For further discussion see Note 15,  Investments Accounted for by the Equity 
Method and Variable Interest Entities. 

Retail Customer Credit Risk

The Company is exposed to retail credit risk through the Company's retail electricity providers, which serve C&I customers 
and the Mass market. Retail credit risk results in losses when a customer fails to pay for services rendered. The losses may result 
from both nonpayment of customer accounts receivable and the loss of in-the-money forward value. The Company manages retail 
credit risk through the use of established credit policies that include monitoring of the portfolio and the use of credit mitigation 
measures such as deposits or prepayment arrangements.

As of December 31, 2018, the Company's retail customer credit exposure to C&I and Mass customers was diversified across 
many customers and various industries, as well as government entities. The Company is also subject to risk with respect to its 
residential solar customers. The Company's bad debt expense was $85 million, $68 million, and $45 million for the years ending 
December 31, 2018, 2017, and 2016, respectively.  Current economic conditions may affect the Company's customers' ability to 
pay bills in a timely manner, which could increase customer delinquencies and may lead to an increase in bad debt expense.

Note 5 — Accounting for Derivative Instruments and Hedging Activities 

ASC 815 requires the Company to recognize all derivative instruments on the balance sheet as either assets or liabilities and 
to measure them at fair value each reporting period unless they qualify for a NPNS exception.  The Company may elect to designate 
certain derivatives as cash flow hedges, if certain conditions are met, and defer the change in fair value of the derivatives to 
accumulated OCI, until the hedged transactions occur and are recognized in earnings. 

For derivatives that are not designated as cash flow hedges or do not qualify for hedge accounting treatment, the changes 
in the fair value will be immediately recognized in earnings.  Certain derivative instruments may qualify for the NPNS exception 
and are therefore exempt from fair value accounting treatment.  ASC 815 applies to NRG's energy related commodity contracts, 
interest rate swaps, and equity contracts.

As the Company engages principally in the trading and marketing of its generation assets and retail businesses, some of 
NRG's commercial activities qualify for NPNS accounting. Most of the retail load contracts either qualify for the NPNS exception 
or fail to meet the criteria for a derivative and the majority of the retail supply and fuels supply contracts are recorded under mark-
to-market accounting.  All of NRG's hedging and trading activities are subject to limits within the Company's Risk Management 
Policy.

139

Energy-Related Commodities

To manage the commodity price risk associated with the Company's competitive supply activities and the price risk associated 
with wholesale power sales from the Company's electric generation facilities and retail power sales from NRG's retail businesses, 
NRG enters into a variety of derivative and non-derivative hedging instruments, utilizing the following:

• 

• 

• 

Forward contracts, which commit NRG to purchase or sell energy commodities or purchase fuels in the future;

Futures contracts, which are exchange-traded standardized commitments to purchase or sell a commodity or financial 
instrument;

Swap agreements, which require payments to or from counterparties based upon the differential between two prices for 
a predetermined contractual, or notional, quantity;

•  Option contracts, which convey to the option holder the right but not the obligation to purchase or sell a commodity;

•  Extendable swaps, which include a combination of swaps and options executed simultaneously for different periods.  This 
combination of instruments allows NRG to sell out-year volatility through call options in exchange for natural gas swaps 
with fixed prices in excess of the market price for natural gas at that time.  The above-market swap combined with its 
later-year call option are priced in aggregate at market at the trade's inception; and

•  Weather derivative products used to mitigate a portion of lost revenue due to weather.

The objectives for entering into derivative contracts designated as hedges include:

• 

• 

• 

Fixing the price of a portion of anticipated power purchases for the Company's retail sales;

Fixing the price for a portion of anticipated future electricity sales that provides an acceptable return on the Company's 
electric generation operations; and

Fixing the price of a portion of anticipated fuel purchases for the operation of the Company's power plants.

NRG's trading and hedging activities are subject to limits within the Company's Risk Management Policy. These contracts 
are recognized on the balance sheet at fair value and changes in the fair value of these derivative financial instruments are recognized 
in earnings.

As of December 31, 2018, NRG's derivative assets and liabilities consisted primarily of the following:

• 

• 

Forward and financial contracts for the purchase/sale of electricity and related products economically hedging NRG's 
generation assets' forecasted output or NRG's retail load obligations through 2034;

Forward and financial contracts for the purchase of fuel commodities relating to the forecasted usage of NRG's generation 
assets through 2019; and

•  Other energy derivatives instruments extending through 2029.

Also, as of December 31, 2018, NRG had other energy-related contracts that did not meet the definition of a derivative 

instrument or qualified for the NPNS exception and were therefore exempt from fair value accounting treatment as follows:

•  Load-following forward electric sale contracts extending through 2034;

• 

Power tolling contracts through 2029;

•  Coal purchase contracts through 2021;

• 

Power transmission contracts through 2025;

•  Natural gas transportation contracts and storage agreements through 2030; and

•  Coal transportation contracts through 2029.

Interest Rate Swaps

NRG is exposed to changes in interest rates through the Company's issuance of variable rate debt. In order to manage the 
Company's interest rate risk, NRG enters into interest rate swap agreements.  As of December 31, 2018, NRG's  derivative assets 
consisted of interest rate derivative instruments on recourse debt extending through 2021. 

140

Volumetric Underlying Derivative Transactions

The following table summarizes the net notional volume buy/(sell) of NRG's open derivative transactions broken out by 
commodity, excluding those derivatives that qualified for the NPNS exception as of December 31, 2018 and 2017. Option contracts 
are reflected using delta volume.   Delta volume equals the notional volume of an option adjusted for the probability that the option 
will be in-the-money at its expiration date.

Accounting guidelines require a high degree of correlation between the derivative and the hedged item throughout the 
period in order to qualify as a cash flow hedge.  As of December 31, 2016, the Company's regression analysis for certain yield  
interest rate swaps, while positively correlated, did not meet the required threshold for cash flow hedge accounting. As a result, 
the Company de-designated these derivatives as cash flow hedges as of December 31, 2016, and prospectively marked these 
derivatives to market through the income statement until the assets were sold.

The Company's regression analysis for certain Yield interest rate swaps, while positively correlated, no longer contain 

matching terms for cash flow hedge accounting.  As a result, the Company voluntarily de-designated these derivatives as cash 
flow hedges as of April 28, 2017, and prospectively marked these derivatives to market through the income statement until  the 
assets were sold.

Impact of Derivative Instruments on the Statement of Operations

Unrealized gains and losses associated with changes in the fair value of derivative instruments not accounted for as cash 

flow hedges are reflected in current period earnings.

The reversal of gain or loss positions acquired as part of acquisitions were valued based upon the forward prices on the 
acquisition dates.  The roll-off amounts were offset by realized gains or losses at the settled prices and are reflected in revenue or 
cost of operations during the same period.

For the year ended December 31, 2018, the $97 million gain from economic hedge positions was primarily the result of an 

increase in the value of forward purchases of ERCOT heat rate contracts due to ERCOT heat rate expansion.

For the year ended December 31, 2017, the $159 million gain from economic hedge positions was primarily the result of an 

increase in the value of forward purchases of ERCOT heat rate contracts due to ERCOT heat rate expansion.

For the year ended December 31, 2016, the $12 million  gain from economic hedge positions was primarily the result of an 

increase in the value of forward purchases of natural gas due to an increase in natural gas prices.

Credit Risk Related Contingent Features

Certain of the Company's hedging agreements contain provisions that require the Company to post additional collateral if 
the counterparty determines that there has been deterioration in credit quality, generally termed "adequate assurance" under the 
agreements, or require the Company to post additional collateral if there were a one notch downgrade in the Company's credit 
rating.   The collateral required for contracts that have adequate assurance clauses that are in net liability positions as of December 31, 
2018 was $16 million.  The collateral required for contracts with credit rating contingent features that are in a net liability position 
as of December 31, 2018 was $14 million.  The Company is also a party to certain marginable agreements under which it has a 
net  liability  position,  but  the  counterparty  has  not  called  for  the  collateral  due,  which  was  approximately  $11  million  as  of 
December 31, 2018.

See Note 4, Fair Value of Financial Instruments, for discussion regarding concentration of credit risk.

 Note 6 — Nuclear Decommissioning Trust Fund 

NRG's Nuclear Decommissioning Trust Fund assets, which are for the decommissioning of STP, are comprised of securities 
classified as available-for-sale and recorded at fair value based on actively quoted market prices. Although NRG is responsible 
for managing the decommissioning of its 44% interest in STP, the predecessor utilities that owned STP are authorized by the PUCT 
to collect decommissioning funds from their ratepayers to cover decommissioning costs on behalf of NRG. NRC requirements 
determine the decommissioning cost estimate which is the minimum required level of funding. In the event that funds from the 
ratepayers that accumulate in the nuclear decommissioning trust are ultimately determined to be inadequate to decommission the 
STP facilities, the utilities will be required to collect through rates charged to rate payers all additional amounts, with no obligation 
from NRG, provided that NRG has complied with PUCT rules and regulations regarding decommissioning trusts. Following 
completion of the decommissioning, if surplus funds remain in the decommissioning trusts, any excess will be refunded to the 
respective ratepayers of the utilities.

NRG accounts for the Nuclear Decommissioning Trust Fund in accordance with ASC 980, Regulated Operations, or ASC 
980, because the Company's nuclear decommissioning activities are subject to approval by the PUCT, with regulated rates that 
are designed to recover all decommissioning costs and that can be charged to and collected from the ratepayers per PUCT mandate. 
Since  the  Company  is  in  compliance  with  PUCT  rules  and  regulations  regarding  decommissioning  trusts  and  the  cost  of 
decommissioning is the responsibility of the Texas ratepayers, not NRG, all realized and unrealized gains or losses (including 
other-than-temporary  impairments)  related  to  the  Nuclear  Decommissioning  Trust  Fund  are  recorded  to  the  Nuclear 
Decommissioning Trust liability and are not included in net income or accumulated other comprehensive income, consistent with 
regulatory treatment.

The following table summarizes the aggregate fair values and unrealized gains and losses for the securities held in the trust 

funds, as well as information about the contractual maturities of those securities.

Note 9 — Asset Impairments 

2018 Impairment Losses

Guam — During the fourth quarter of 2018, the Company concluded its wholly-owned subsidiary, NRG Solar Guam, 
LLC, was held for sale after board approval and advanced negotiations to sell the business. Accordingly, the Company recorded 
the assets and liabilities at fair market value as of December 31, 2018 based on the contractual sale price, which resulted in an 
impairment loss of $12 million.  On February 20, 2019, the Company completed the sale of Guam for cash consideration of 
approximately $8 million. 

Keystone and Conemaugh — On September 5, 2018, the Company sold its approximately 3.7% interests in the Keystone 
and Conemaugh generating stations. NRG recorded impairment losses of $14 million for Keystone and $14 million for Conemaugh 
to adjust the carrying amount of the assets to fair value based on the contractual sale price.

Dunkirk — During the second quarter of 2018, NRG ceased its development of the project to add gas capability at the Dunkirk 
generating station. The project was put on hold in 2015 pending the resolution of a lawsuit filed by Entergy Corporation against 
the NYPSC, which challenged the legality of its contract with Dunkirk.  The lawsuit was later dropped and development continued, 
but the delay imposed a new requirement on Dunkirk to enter into the NYISO interconnection study process. The NYISO studies 
have concluded that extensive electric system upgrades would be necessary for the station to return to service. This would cause 
the  Company  to  incur  a  material  increase  in  cost  and  delay  the  project  schedule  that  would  render  the  project  impractical. 
Consequently, the Company has recorded an impairment loss of $46 million, reducing the carrying amount of the related assets 
to $0. 

Other Impairments — As of December 31, 2018, the Company recorded additional asset impairment losses of approximately 

$13 million and impairment losses on equity method investments of $15 million.

2017 Impairment Losses

South Texas Project — The Company recognized an impairment loss of $1,248 million related to its interest in STP as a 

result of the decrease in the Company's view of long-term power prices in ERCOT.

Indian River — The Company recognized an impairment loss of $36 million for Indian River as a result of the decrease in 

the Company's view of long-term power prices in PJM.

Keystone and Conemaugh — The Company recognized impairment losses of $35 million for Keystone and $35 million for 

Conemaugh as a result of the decrease in the Company's view of long-term power prices in PJM.

Bacliff Project — On June 16, 2017, NRG Texas Power LLC provided notice to BTEC New Albany, LLC that it was exercising 
its right to terminate the Amended and Restated Membership Interest Purchase Agreement, or MIPA, due to the Bacliff Project, 
a new peaking facility at the former P.H. Robinson Electric Generating Station, not achieving commercial completion by the 
contractual expiration date of May 31, 2017.  As a result of the MIPA termination, the Company recorded an impairment loss of 
$41 million to reduce the carrying amount of the related construction in progress to $0 during the second quarter of 2017.  Subsequent 
to the MIPA termination, BTEC filed claims against NRG Texas Power LLC with respect to the termination of the MIPA and NRG 
filed counterclaims against BTEC as further described in Note 21, Commitments and Contingencies. On June 7, 2018, the parties 
resolved all claims and counterclaims in the lawsuit.

Petra Nova Parish Holdings — In connection with the preparation of the annual budget during the fourth quarter, management 
revised its view of oil production expectations with respect to Petra Nova Parish Holdings. As a result, the Company reviewed its 
50% interest in Petra Nova Parish Holdings for impairment utilizing the other-than-temporary impairment model. In determining 
fair value, the Company utilized an income approach and considered project specific assumptions for the future project cash flows. 
The carrying amount of the Company's equity method investment exceeded the fair value of the investment and the Company 
concluded that the decline is considered to be other-than-temporary.  As a result, the Company measured the impairment loss as 
the difference between the carrying amount and the fair value of the investment and recorded an impairment loss of $69 million.

Other Impairments — During the year ended 2017, the Company recorded impairment losses of $29 million in connection 
with renewable assets that were not divested as part of the sale of NRG Yield and the Renewables Platform. In addition, the 
Company recorded an impairment loss of $20 million related to excess SO2 allowances and $10 million in impairment losses for 
other investments.

2016 Impairment Losses  

Rockford — As described in Note 3,  Acquisitions, Discontinued Operations and Dispositions, on May 12, 2016, the Company 
entered into an agreement with RA Generation, LLC to sell 100% of its interests in the Rockford generating stations for cash 
consideration of $55 million.  The transaction triggered an indicator of impairment as the sale price was less than the carrying 
amount of the assets, and, as a result, the assets were considered to be impaired.  The Company measured the impairment loss as 
the difference between the carrying amount of the assets and the agreed-upon sale price.  The Company recorded an impairment 
loss of $17 million during the year ended December 31, 2016, to reduce the carrying amount of the assets held for sale to their 
fair market value.  

Long Beach — During the fourth quarter of 2016, the Company determined that by the end of 2017 it would retire its Long 
Beach generation station located in Long Beach, California.  The generating station was not awarded a PPA extension in SCE's 
capacity auction during the fourth quarter of 2016 for the PPA set to expire on July 31, 2017.  The Company considered this to be 
an indicator of impairment and performed an impairment test.  The Company measured the impairment loss as the difference 
between the carrying amount and the fair value of the assets and recorded an impairment loss of $36 million. Subsequently, 
management decided to continue to operate in 2018, which did not significantly impact fair value. 

Petra Nova Parish Holdings — During the first quarter of 2016, management changed its plans with respect to its future 
capital commitments driven in part by the continued decline in oil prices. As a result, the Company reviewed its 50% interest in 
Petra Nova Parish Holdings for impairment utilizing the other-than-temporary impairment model. In determining fair value, the 
Company utilized an income approach and considered project specific assumptions for the future project cash flows.  The carrying 
amount of the Company's equity method investment exceeded the fair value of the investment and the Company concluded that 
the decline is considered to be other-than-temporary..  As a result, the Company measured the impairment loss as the difference 
between the carrying amount and the fair value of the investment and recorded an impairment loss of $140 million.

Community Wind North and Sherbino — During the fourth quarter of 2016, the Company offered several projects to 
NRG Yield including its interest in Community Wind North. The offer price was below its carrying amount and this decline in 
fair value was determined to be other-than-temporary. Accordingly, the Company recorded an impairment loss of $36 million to 
reduce its carrying amount to fair value. In connection with the preparation of the annual budget, the Company noted that due to 
the anticipated difficulty in refinancing Sherbino's debt, the project's fair value had decreased significantly below its carrying 
amount and determined the impairment to be other-than-temporary.  Accordingly, the Company determined that an impairment 
existed and recorded an impairment loss on its investment in Sherbino of $70 million.  

Other  Impairments  —  During  2016,  the  Company  recorded  other  impairment  losses  of  $29  million  in  connection  with 
renewable assets that were not divested as part of the sale of NRG Yield and the Renewables Platform. In addition, the Company 
also recorded impairment losses of $23 million in excess SO2  allowances, $19 million for other intangible assets, $19 million in 
previously purchased solar panels and $22 million in other investments.

Note 10 — Goodwill and Other Intangibles 

Goodwill 

NRG's goodwill balance was $573 million and $539 million as of December 31, 2018 and 2017, respectively. The increase 
in goodwill is due to the acquisition of XOOM. As of December 31, 2018 and 2017, NRG had approximately $366 million and $460 
million, respectively, of goodwill that is deductible for U.S. income tax purposes in future periods. As of December 31, 2018, goodwill 
consisted of $165 million associated with the acquisition of Midwest Generation and $408 million for Retail business acquisitions, 
including Texas non-commodity and XOOM.

2017 Impairments of Goodwill  

BETM — During the fourth quarter of 2017, the Company concluded that BETM was held for sale following board approval 
and advanced negotiations to sell the business.  Accordingly, the Company recorded the assets and liabilities at fair market value as 
of  December 31, 2017, which resulted in an impairment loss of $90 million to record BETM's goodwill at fair market value.  The 
remaining goodwill balance for BETM of $21 million was included within non-current assets held-for-sale as of December 31, 2017. 

2016 Impairments of Goodwill  

During the year ended December 31, 2016, the Company recorded a goodwill impairment charge of $337 million related 

to its Texas Generation reporting unit, reducing the goodwill balance for Texas Generation to zero.

147

 
 
 
 
 
 
 
In connection with the annual impairment assessment, the Company performed step one of the two-step impairment test 
for the Texas Generation reporting unit, for which $1.7 billion of goodwill was recognized as part of the Texas Genco acquisition in 
2006 and $1.4 billion was written off in 2015.  The Company determined the fair value of the Texas Generation reporting unit 
primarily using an income approach through which the Company applied a discounted cash flow methodology to the long-term 
budgets for all plants in the regions.  Significant inputs impacting the income approach include the Company's views of power and 
fuel prices for the first five-year period and the Company's view for the longer term, which were finalized in connection with the 
preparation of the annual budget, projected generation based on an hourly dispatch meant to simulate the dispatch of each unit into 
the power market which is impacted by power prices, fuel prices, and the physical and economic characteristics of each plant, 
intangible value to Texas Generation for synergies it provides to NRG's retail businesses, and the discount rate applied to cash flow 
projections.  Under step one, the estimated fair value of the Texas Generation invested capital was 43% below its carrying value as 
of December 31, 2016, and the Company concluded step two was required.  Based on the results of step two of the impairment test, 
the Company determined the carrying amount of the reporting unit was higher than the fair value, and accordingly, the Company 
recognized an impairment loss of $337 million as of December 31, 2016.

Intangible Assets 

The Company's intangible assets as of December 31, 2018, primarily reflect intangible assets established with the acquisitions 
of various companies, including Texas Genco, Reliant Energy, Green Mountain Energy, Dominion, XOOM, Discount Power, Energy 
Alternatives, Energy Plus, Energy Systems, Energy Curtailment Specialists, Pioneer Energy, Stat Energy and Source Power & Gas. 
Intangible assets are comprised of the following:

•  Energy supply contracts — These represent the fair value at the acquisition date of in-market contracts for the purchase of 
energy to serve retail electric customers. The contracts are amortized to cost of operations based on the expected delivery 
under the respective contracts.

•  Customer contracts — These intangibles represent the fair value at the acquisition date of contracts that primarily provide 
electricity to Reliant Energy's and Green Mountain Energy's C&I customers. These contracts are amortized to revenues 
based on expected volumes to be delivered for the portfolio.

•  Customer relationships — These intangibles represent the fair value at the acquisition date of acquired businesses' customer 
base. The customer relationships are amortized to depreciation and amortization expense based on the expected discounted 
future net cash flows by year. 

•  Marketing partnerships — These intangibles represent the fair value at the acquisition date of existing agreements with 
loyalty and affinity partners.  The marketing partnerships are amortized to depreciation and amortization expense based on 
the expected discounted future net cash flows by year.

Trade names — These intangibles are amortized to depreciation and amortization expense on a straight-line basis.

• 
•  Emission Allowances — These intangibles primarily consist of SO2 and NOx emission allowances established with the 2006 
Texas Genco acquisition and also include RGGI emission credits which NRG began purchasing in 2009. These emission 
allowances are held-for-use and are amortized to cost of operations, with NOx allowances amortized on a straight-line basis 
and SO2 allowances and RGGI credits amortized based on units of production. During the year ended December 31, 2018, 
the Company recorded an impairment loss of $5 million to reduce the value of excess SO2 allowances to zero.
In-market fuel (gas and nuclear) contracts — These intangibles were established with the Texas Genco acquisition in 2006 
and are amortized to cost of operations over expected volumes over the life of each contract.

• 

•  Other — Consists of renewable energy credits and costs to extend the operating license for STP Units 1 and 2.

Intangible assets held-for-sale — From time to time, management may authorize the transfer from the Company's emission 
bank of emission allowances held-for-use to intangible assets held-for-sale.  Emission allowances held-for-sale are included in other 
non-current assets on the Company's consolidated balance sheet and are not amortized, but rather expensed as sold. As of  December 31, 
2018 and 2017, the value of emission allowances held-for-sale is $12 million and $9 million, respectively, and is managed within 
the Corporate segment. Once transferred to held-for-sale, these emission allowances are prohibited from moving back to held-for-
use.

Out-of-market contracts — Due primarily to business acquisitions, NRG acquired certain out-of-market contracts, which are 
classified as non-current liabilities on NRG's consolidated balance sheet.  These include out-of-market lease contracts of  $121 million
acquired  in  the  acquisition  of  Midwest  Generation.  These  out-of-market  contracts  are  amortized  to  cost  of  operations. As  of 
December 31, 2018 and 2017, the Company had accumulated amortization for out-of-market contracts of $37 million and $29 million, 
respectively. Upon adoption of ASC 842, Leases, on January 1, 2019, out-of-market lease contracts are included as a component of 
right-of-use assets.

Recourse Debt

Issuance of 2048 Convertible Senior Notes  

During the second quarter of 2018, NRG issued $575 million in aggregate principal amount of 2.75% Convertible Senior 
Notes due 2048, or the Convertible Notes.  The Convertible Notes are convertible, under certain circumstances, into the Company's 
common stock, cash or a combination thereof (at NRG's option) at an initial conversion price of $47.74 per common share, which 
is equivalent to an initial conversion rate of approximately 20.9479 shares of common stock per $1,000 principal amount of 
Convertible Notes. Interest on the Convertible Notes is payable semi-annually in arrears on June 1 and December 1 of each year, 
commencing on December 1, 2018. The Convertible Notes mature on June 1, 2048, unless earlier repurchased, redeemed or 
converted in accordance with their terms. The Convertible Notes are guaranteed by certain NRG subsidiaries. Prior to the close 
of business on the business day immediately preceding December 1, 2024, the Convertible Notes will be convertible only upon 
the occurrence of certain events and during certain periods, and thereafter during specified periods as follows:

• 

from December 1, 2024 until the close of business on the second scheduled trading day immediately before 

June 1, 2025; and 

• 

from December 1, 2047 until the close of business on the second scheduled trading day immediately before 

the maturity date.  

The Convertible Notes are accounted for in accordance with ASC 470-20, Debt with Conversion and Other Options. Under 
ASC 470-20, issuers of convertible debt instruments that may be settled in cash upon conversion, including partial cash settlement, 
are required to separately account for the liability (debt) and equity (conversion option) components. The carrying amount of the 
liability component at issuance date of $472 million was calculated by estimating the fair value of similar liabilities without a 
conversion feature. The residual principal amount of the notes of $103 million was allocated to the equity component with offset 
to debt discount. The debt discount will be amortized to interest expense using the effective interest method over seven years 
which is determined to be the expected life of the Convertible Notes.

The Company incurred approximately $12 million in transaction costs in connection with the issuance of the notes. These 
costs were allocated to the liability and equity components in proportion to the allocation of proceeds. Transaction costs of $10 
million, allocated to the liability component, were recognized as deferred financing costs and are amortized over the seven years. 
Transaction costs of $2 million, allocated to the equity component, were recognized as a reduction of additional paid-in capital.

Issuance of 2028 Senior Notes 

On December 7, 2017, NRG issued $870 million of aggregate principal amount at par of 5.75% senior unsecured notes due 
2028. The 2028 Senior Notes are senior unsecured obligations of NRG and are guaranteed by certain of its subsidiaries. Interest 
is paid semi-annually beginning on July 15, 2018, until the maturity date of January 15, 2028.  The proceeds from the issuance 
of the 2028 Senior Notes were utilized to redeem the Company's 6.625% Senior Notes due 2023.

2018 Senior Note Repurchases  

During the year ended December 31, 2018 the Company completed senior note repurchases, as detailed in the table below. 
In  addition,  during  the  year  ended  December 31,  2018,  a  $38  million  loss  on  debt  extinguishment  was  recorded  for  these 
repurchases, which included the write-off of previously deferred financing costs of $7 million.

As of December 31, 2018, NRG had the following outstanding issuances of senior notes with an early redemption feature, 

or Senior Notes:

i. 

ii. 

iii. 

iv. 

6.250% senior notes, issued April 21, 2014 and due November 1, 2024, or the 2024 Senior Notes;

7.250% senior notes, issued May 23, 2016 and due May 15, 2026, or the 2026 Senior Notes; 

6.625% senior notes, issued August 2, 2016 and due January 15, 2027, or the 2027 Senior Notes; and

5.750% senior notes, issued December 7, 2017 and due January 15, 2028, or the 2028 Senior Notes.

The Company periodically enters into supplemental indentures for the purpose of adding entities under the Senior Notes 

as guarantors.

The indentures and the forms of notes provide, among other things, that the Senior Notes will be senior unsecured obligations 
of NRG. The indentures also provide for customary events of default, which include, among others: nonpayment of principal or 
interest; breach of other agreements in the indentures; defaults in failure to pay certain other indebtedness; the rendering of 
judgments to pay certain amounts of money against NRG and its subsidiaries; the failure of certain guarantees to be enforceable; 
and certain events of bankruptcy or insolvency.  Generally, if an event of default occurs, the Trustee or the Holders of at least 
25% in principal amount of the then outstanding series of Senior Notes may declare all of the Senior Notes of such series to be 
due and payable immediately.  The terms of the indentures, among other things, limit NRG's ability and certain of its subsidiaries' 
ability to return capital to stockholders, grant liens on assets to lenders and incur additional debt.  Interest is payable semi-annually 
on the Senior Notes until their maturity dates.

On June 30, 2016, NRG replaced the previous senior credit facility, consisting of its Term Loan Facility and Revolving 

Credit Facility, with a new senior secured facility, or the Senior Credit Facility, which includes the following: 

•  A $1.9 billion term loan facility, or the 2023 Term Loan Facility, with a maturity date of June 30, 2023, which will pay 
interest at a rate of LIBOR plus 2.75%, with a LIBOR floor of 0.75%.  The debt was issued at 99.50% of face value; 
the discount will be amortized to interest expense over the term of the loan. Repayments under the 2023 Term Loan 
Facility will consist of 0.25% of principal per quarter, with the remainder due at maturity. On January 24, 2017, NRG 
repriced the 2023 Term Loan Facility, reducing the interest rate margin by 50 basis points to LIBOR plus 2.25%, the 
LIBOR floor remains 0.75%. On March 21, 2018, NRG again repriced the 2023 Term Loan Facility, reducing the interest 
rate margin by 50 basis points to LIBOR plus 1.75% and reducing the LIBOR floor to 0.00%. 

•  A $289 million revolving senior credit facility, or the Tranche A Revolving Facility, with a maturity date of July 1, 2018 
and a $2.2 billion revolving senior credit facility, or the Tranche B Revolving Facility, with a maturity date of June 30, 
2021, which both pay interest at a rate of LIBOR plus 2.25%.   On May 7, 2018, NRG entered into the third amendment 
agreement extending the maturity date of the Tranche A revolving facility to June 30, 2021, for the Tranche A accepting 
lender.

 In accordance with the terms of the Credit Agreement, on October 5, 2018, the Company initiated an asset sale offer to 
purchase a portion of its Term Loan following the sale of NRG Yield and the Renewables Platform. The offer expired on November 
5, 2018 and $260 million of Term Loan holders accepted the offer. As a result, the Company prepaid $155 million of Term Loans 
as part of its de-leveraging plan, as well as established an incremental first lien secured term loan facility under the Senior Credit 
Facility in the aggregate principal amount of $105 million on the same terms and conditions to stay within its debt reduction 
target. In addition, a $3 million loss on debt extinguishment was recorded, which included the write-off of previously deferred 
financing costs of $2 million.

In accordance with the terms of the credit agreement, upon the consummation of the sales of the South Central Portfolio 
and Carlsbad, the Company will initiate asset sale offers to purchase a portion of its Term Loan. The Company has one year from 
the dates of each sale to initiate the offer.

Non-Recourse Debt

The following are descriptions of certain indebtedness of NRG's subsidiaries that are outstanding as of December 31, 2018.  

All of NRG's non-recourse debt is secured by the assets in the respective project subsidiaries as further described below. 

Midwest Generation

On April 7, 2016, Midwest Generation, LLC, or MWG, entered into an agreement to sell certain quantities of unforced 
capacity that has cleared various PJM Reliability Pricing Model auctions to a trading counterparty for net proceeds of $253 
million.  MWG will continue to operate the applicable generation facilities and remains responsible for performance penalties 
and eligible for performance bonus payments, if any. Accordingly, MWG will continue to account for all revenues and costs as 
before; however, the proceeds will be recorded as a financing obligation while capacity payments by PJM to the counterparty 
will be reflected as debt amortization and interest expense through the end of the 2018/19 delivery year. MWG will amortize the 
upfront discount to interest expense, at an effective interest rate of 4.39%, over the term of the arrangement, through June 2019.  
As of December 31, 2018, $48 million was outstanding. 

Agua Caliente Borrower I

On January 22, 2019, the lenders of the Agua Borrower I debt notified the Company of certain defaults under the financing 
agreement as it relates to the bankruptcy filing made by PG&E on January 29, 2019. PG&E is the offtaker of the underlying 
contracts, which are material. The financing was entered into along with Agua Caliente Borrower 2, LLC, a subsidiary of Clearway 
Energy Inc., which is joint and several to the parties. The Company is working with the lenders to determine a path forward. 

Note 12  — Asset Retirement Obligations 

The  Company's AROs  are  primarily  related  to  the  environmental  obligations  related  to  nuclear  decommissioning,  ash 
disposal,  site  closures,  and  fuel  storage  facilities  and  future  dismantlement  of  equipment  on  leased  property.  In  addition,  the 
Company has also identified conditional AROs for asbestos removal and disposal, which are specific to certain power generation 
operations.   

See Note 6, Nuclear Decommissioning Trust Fund, for a further discussion of the Company's nuclear decommissioning 
obligations.  Accretion for the nuclear decommissioning ARO and amortization of the related ARO asset are recorded to the Nuclear 
Decommissioning Trust Liability to the ratepayers and are not included in net income, consistent with treatment per ASC 980, 
Regulated Operations. Nuclear decommissioning ARO liabilities were $282 million and $269 million as of December 31, 2018
and 2017, respectively.

The following table represents the balance of ARO obligations as of December 31, 2018 and 2017, along with the additions, 

reductions and accretion related to the Company's ARO obligations for the year ended December 31, 2018:

Note 13 — Benefit Plans and Other Postretirement Benefits 

NRG sponsors and operates defined benefit pension and other postretirement plans.  

NRG pension benefits are available to eligible non-union and union employees through various defined benefit pension 
plans.  These benefits are based on pay, service history and age at retirement.  Most pension benefits are provided through tax-
qualified plans.  NRG also provides postretirement health and welfare benefits for certain groups of employees.  Cost sharing 
provisions vary by the terms of any applicable collective bargaining agreements.

156

 
NRG maintains two separate qualified pension plans, the NRG Pension Plan for Bargained Employees and the NRG Pension 
Plan. Employees of NRG participate in each of the pension plans, depending upon whether their employment is covered by a 
bargaining agreement. 

NRG and GenOn entered into a Restructuring Support Agreement in which NRG agreed to retain GenOn's pension liability 
for service provided by GenOn employees prior to the completion of the GenOn reorganization. NRG determined that the retention 
of this liability was probable and recorded the estimated accumulated pension benefit obligation as of December 31, 2017 of $92 
million,  which  reflects  a  $13  million  contribution  made  by  NRG  to  the  plan  in  2017,  in  other  non-current  liabilities  with  a 
corresponding loss from discontinued operations. NRG also agreed to retain the liability for GenOn's post-employment and retiree 
health and welfare benefits with the obligation capped at $25 million. NRG's obligation for both of these liabilities was revalued 
at GenOn's emergence from bankruptcy. 

NRG expects to contribute $41 million to the Company's pension plans in 2019, of which $13 million relates to GenOn.

NRG Defined Benefit Plans

The annual net periodic benefit cost/(credit) related to NRG's pension and other postretirement benefit plans include the 

following components:

Service cost benefits earned
Interest cost on benefit obligation
Expected return on plan assets
Amortization of unrecognized net loss
Settlement/curtailment expense

(a)  NRG's liability for GenOn's other postretirement benefit plans was capped at $25 million, with the final liability assumed determined as of GenOn's 
emergence from bankruptcy. As of December 31, 2017, the liability was $38 million so NRG's obligation was recorded at the $25 million cap. Upon 
emergence, the retained liability was $23 million, therefore NRG is obligated for the full retained liability of the plans.

As a result of GenOn's deconsolidation during 2017, NRG reduced the loss recorded in other comprehensive income by $28 

million related to GenOn's pension and other postretirement benefits.

The  Company's  estimated  unrecognized  loss  and  unrecognized  prior  service  cost  for  NRG's  pension  plan  that  will  be 
amortized from accumulated OCI to net periodic cost over the next fiscal year is $4 million and $0 million, respectively. The 
Company's estimated unrecognized gain and unrecognized prior service credit for NRG's postretirement plan that will be amortized 
from accumulated OCI to net periodic cost over the next fiscal year is less than $1 million and $13 million, respectively.

In accordance with ASC 820, the Company determines the level in the fair value hierarchy within which each fair value 
measurement in its entirety falls, based on the lowest level input that is significant to the fair value measurement in its entirety.  
The fair value of the common/collective trust investments is valued at fair value which is equal to the sum of the market value of 
all of the fund's underlying investments.  Certain common/collective trust investments have readily determinable fair value as 
they  publish  daily  net  asset  value,  or  NAV,  per  share  and  are  categorized  as  Level 2.    Certain  other  common/collective  trust 
investments and partnerships/joint ventures use NAV per share, or its equivalent, as a practical expedient for valuation, and thus 
have been removed from the fair value hierarchy table.

NRG uses December 31 of each respective year as the measurement date for the Company's pension and other postretirement 
benefit plans.  The Company sets the discount rate assumptions on an annual basis for each of NRG's defined benefit retirement 
plans as of December 31.  The discount rate assumptions represent the current rate at which the associated liabilities could be 
effectively settled at December 31.  The Company utilizes the Aon AA Above Median, or AA-AM, yield curve to select the 
appropriate discount rate assumption for each retirement plan.  The AA-AM yield curve is a hypothetical AA yield curve represented 
by a series of annualized individual spot discount rates from 6 months to 99 years.  Each bond issue used to build this yield curve 
must be non-callable, and have an average rating of AA when averaging available Moody's Investor Services, Standard & Poor's 
and Fitch ratings.

NRG employs a total return investment approach, whereby a mix of equities and fixed income investments are used to 
maximize the long-term return of plan assets for a prudent level of risk.  Risk tolerance is established through careful consideration 
of  plan  liabilities,  plan  funded  status,  and  corporate  financial  condition.    The  Investment  Committee  reviews  the  asset  mix 
periodically and as the plan assets increase in future years, the Investment Committee may examine other asset classes such as 
real estate or private equity.  NRG employs a building block approach to determining the long-term rate of return assumption for 
plan assets, with proper consideration given to diversification and rebalancing.  Historical markets are studied and long-term 
historical  relationships  between  equities  and  fixed  income  are  preserved,  consistent  with  the  widely  accepted  capital  market 
principle that assets with higher volatility generate a greater return over the long run.  Current factors such as inflation and interest 
rates are evaluated before long-term capital market assumptions are determined.  Peer data and historical returns are reviewed to 
check for reasonableness and appropriateness.

In 2016, NRG changed the approach utilized to estimate the service cost and interest cost components of net periodic benefit 
cost for pension and postretirement benefit plans. Historically, the Company estimated these components by using a single weighted 
average discount rate derived from the yield curve used to measure the benefit obligation. The Company has elected to use a spot 
rate approach in the estimation of the components of benefit cost by applying specific spot rates along the yield curve to the 
relevant projected cash flows, as this provides a better estimate of service and interest costs. This election is considered a change 
in estimate and, accordingly, has been accounted for starting in 2016. This change does not affect the measurement of NRG's total 
benefit obligation. 

The target allocations of NRG's pension plan assets were as follows for the year ended December 31, 2018:

U.S. equity
Non-U.S. equity
Non-core assets
U.S. fixed income

22%
14%
19%
45%

Plan  assets  are  currently  invested  in  a  diversified  blend  of  equity  and  fixed-income  investments.    Furthermore,  equity 
investments are diversified across U.S., non-U.S., global, and emerging market equities, as well as among growth, value, small 
and large capitalization stocks.

NRG has a 44% undivided ownership interest in STP, as discussed further in Note 26, Jointly Owned Plants.  STPNOC, 
which operates and maintains STP, provides its employees a defined benefit pension plan, as well as postretirement health and 
welfare benefits.  Although NRG does not sponsor the STP plan, it reimburses STPNOC for 44% of the contributions made towards 
its retirement plan obligations.  For the years ended December 31, 2018 and December 31, 2017, NRG reimbursed STPNOC $13 
million and $8 million, respectively, for its contribution to the plans. In 2019, NRG expects to reimburse STPNOC $18 million
for its contribution to the plans. 

The Company has recognized the following in its statement of financial position, statement of operations and accumulated

On May 24, 2016, NRG entered an agreement with Credit Suisse Group to  repurchase 100% of the outstanding shares of its 
$345 million 2.822% preferred stock.  On June 13, 2016, the Company completed the repurchase from Credit Suisse of 100% of 
the outstanding shares at a price of $226 million. The transaction resulted in a gain on redemption of $78 million, measured as 
the difference between the fair value of the cash consideration paid upon redemption of $226 million and the carrying value of 
the preferred stock at the time of the redemption of $304 million. This amount was reflected in net loss available to NRG common 
stockholders in the calculation of earnings per share for the year ended December 31, 2016.

PG&E Bankruptcy - The Company's Agua Caliente and Ivanpah projects are party to PPAs with PG&E. Both projects have 
project financing with the U.S. DOE. On January 29, 2019, PG&E Corp. and subsidiary utility PG&E filed for Chapter 11 bankruptcy 
protection. As part of their filing, PG&E asked the Bankruptcy Court to confirm "exclusive jurisdiction" over their "rights to reject" 
PPAs or other contracts regulated by FERC. As a result of the bankruptcy filing, the Agua Caliente and Ivanpah projects have issued 
notices of events of default under their respective loan agreements. The Company is working with its partners on the projects and 
the loan counterparties, however, given the uncertainty involved in bankruptcy proceedings, it is uncertain whether, and to what 
extent, PG&E's bankruptcy may in the future impact the PPAs and have any resulting impact on the Agua Caliente and Ivanpah 
projects. NRG's maximum exposure to loss is limited to its equity investment, which was $200 million for Agua Caliente and $37 
million for Ivanpah. See Note 11, Debt and Capital Leases for further discussion on Agua Caliente.

Variable Interest Entities

NRG accounts for its interests in certain entities that are considered VIEs under ASC 810, Consolidation, for which NRG is 

not the primary beneficiary, under the equity method.

Through its consolidated subsidiary, NRG Solar Ivanpah LLC, NRG owns a 54.5% interest in Ivanpah Master Holdings, 
LLC, or Ivanpah, the owner of three solar electric generating projects located in the Mojave Desert with a total capacity of 393
MW.  NRG considers this investment a VIE under ASC 810 and NRG is not considered the primary beneficiary.  The Company 
accounts for its interest under the equity method of accounting.

The Ivanpah solar electric generating projects were funded in large part by loans guaranteed by the U.S. DOE and equity 
from the projects' partners.  During the first quarter of 2018, all interested parties sought a restructuring of Ivanpah's debt in order 
to avoid a potential event of default with respect to the loans in connection with several recent events.  Ensuing negotiations 
culminated in a settlement during the second quarter of 2018 between the parties which resulted in certain transactions, including 
the release of reserves totaling $95 million to fund equity distributions to the partners, which reduced the equity at risk, and the 
prepayment of certain of the debt balance outstanding, and the amendment of certain of Ivanpah's governing documents. The equity 
distributions and prepayment of debt were funded by the agreed upon release of reserve funds. These events were considered to 
be a reconsideration event in accordance with ASC 810.  As a result, NRG determined that it is not the primary beneficiary and 
deconsolidated Ivanpah.  NRG recognized a loss of $22 million on the deconsolidation and subsequent recognition of Ivanpah as 
an equity method investment.  The deconsolidation of Ivanpah reduced the Company's assets by approximately $1.3 billion, which 
was primarily property, plant and equipment, and reduced the Company's liabilities by $1.2 billion, which was primarily long-term 
debt. 

165

 
 
 
Other Equity Investments

Gladstone — Through a joint venture, NRG owns a 37.5% interest in Gladstone, a 1,613 MW coal-fueled power generation 
facility in Queensland, Australia. The power generation facility is managed by the joint venture participants and the facility is 
operated by NRG. Operating expenses incurred in connection with the operation of the facility are funded by each of the participants 
in proportion to their ownership interests. Coal is sourced from local mines in Queensland. NRG and the joint venture participants 
receive their respective share of revenues directly from the off takers in proportion to the ownership interests in the joint venture. 
Power generated by the facility is primarily sold to an adjacent aluminum smelter, with excess power sold to the Queensland 
Government-owned utility under long-term supply contracts. NRG's investment in Gladstone was $140 million as of December 31, 
2018.   

Entities that are Consolidated

The Company has a controlling financial interest in certain entities which have been identified as VIEs under ASC 810.  These 
arrangements are primarily related to tax equity arrangements entered into with third-parties in order to finance the cost of solar 
energy  systems  under  operating  leases  eligible  for  certain  tax  credits  as  further  described  in  Note  2,  Summary  of  Significant 
Accounting Policies.

Basic income/(loss) per common share is computed by dividing net income/(loss) less accumulated preferred stock dividends 
by the weighted average number of common shares outstanding. Shares issued and treasury shares repurchased during the year 
are weighted for the portion of the year that they were outstanding. Diluted income/(loss) per share is computed in a manner 
consistent  with  that  of  basic  income/(loss)  per  share,  while  giving  effect  to  all  potentially  dilutive  common  shares  that  were 
outstanding during the period. 

Dilutive effect for equity compensation and other equity instruments — The outstanding non-qualified stock options, non-
vested restricted stock units, and market stock units are not considered outstanding for purposes of computing basic income/(loss) 
per share. However, these instruments are included in the denominator for purposes of computing diluted income/(loss) per share 
under the treasury stock method.  The if-converted method was used to determine the dilutive effect of the 2048 Convertible Senior 
Notes for the year ended December 31, 2018. During 2016, the Company repurchased 100% of the outstanding shares of its 2.822%
% preferred stock.

The Company's segment structure reflects how management currently makes financial decisions and allocates resources.  
The Company's businesses are segregated into the Generation, Retail and corporate segments. Generation includes all power 
plant activities, domestic and international, as well as renewables. Retail includes Mass customers and Business Solutions, which 
includes C&I customers and other distributed and reliability products. Intersegment sales are accounted for at market. 

As described in Note 3, Acquisitions, Discontinued Operations and Dispositions, the Company has determined that the 
South  Central  Portfolio,  NRG Yield  Inc.  and  its  Renewables  Platform,  Carlsbad,  and  GenOn  all  qualified  for  treatment  as 
discontinued  operations.  The  financial  information  for  all  historical  periods  has  been  recast  to  reflect  the  presentation  of 
discontinued operations within the corporate segment.

NRG's  chief  operating  decision  maker,  its  chief  executive  officer,  evaluates  the  performance  of  its  segments  based  on 
operational measures including adjusted earnings before interest, taxes, depreciation and amortization, or Adjusted EBITDA, 
free cash flow and capital for allocation, as well as net income/(loss) and net income/(loss) attributable to NRG Energy, Inc.

During the year ended December 31, 2018, the Company had one customer in the Generation segment that comprised 
11% of the Company's consolidated revenues.  During the years ended December 31, 2017 and 2016, the Company had no 
customer that comprised more than 10% of the Company's consolidated revenues.

For the year ended December 31, 2018, NRG's overall effective tax rate was different than the federal statutory tax rate of 
21% primarily due to a tax benefit for the change in valuation allowance, the generation of PTCs from various wind facilities and 
establishment of the previously sequestered AMT credit receivable, partially offset by current state tax expense.

For the year ended December 31, 2017, NRG's overall effective tax rate was different than the federal statutory tax rate of 
35% primarily due to tax expense recorded from the revaluation of the existing net deferred tax asset and state taxes, partially 
offset by the change in valuation allowance, establishing the AMT credit and the generation of PTCs from various wind facilities. 
The tax expense recorded for revaluation of the net deferred tax asset is required to reflect the reduction in the corporate income 
tax rate from 35% to 21% in accordance with the Tax Act. 

 For the year ended December 31, 2016, NRG's overall effective tax rate was different than the federal statutory tax rate of 
35% primarily due to the change in valuation allowance and the impact of non-taxable equity earnings, partially offset by the state 
tax rate change and the generation of PTCs from various wind facilities.

The primary driver for the decrease in the net deferred tax asset from $113 million as of December 31, 2017 to a net deferred 
tax liability of $19 million as of December 31, 2018 is the removal of NRG Yield, Inc.'s net deferred tax asset upon their sale in 
2018.  The  2017  beginning  deferred  balance  included  $128  million  of  NRG Yield  Inc.'s  net  deferred  tax  assets,  which  were 
subsequently moved to discontinued operations prior to the sale.  

Deferred tax assets and valuation allowance

        Net deferred tax balance — As of December 31, 2018 and 2017, NRG recorded a net deferred tax asset of $3.8 billion and 
$2.0 billion, respectively. The Company believes the federal and certain state net deferred tax assets may not be realizable under 
a "more likely than not" measurement and as such, a valuation allowance has been recorded to reduce the asset accordingly. The 
determination is based on the Company's assessment of cumulative and forecasted pretax book earnings and the future reversal 
of existing taxable temporary differences.

Based on the Company's assessment of positive and negative evidence, including available tax planning strategies, NRG 
believes  that  it  is  more  likely  than  not  that  a  benefit  will  not  be  realized  on  $3.8  billion  and  $1.9  billion  of  tax  assets  as of 
December 31, 2018, and 2017, respectively, thus a valuation allowance has been recorded. The net deferred tax liability of $19 
million as of December 31, 2018 is predominantly due to a foreign net deferred tax liability of $16 million and a net deferred tax 
liability for the state of Texas.

NOL  carryforwards — At  December 31,  2018,  the  Company  had  tax  effected  cumulative  domestic  NOLs  consisting  of 
carryforwards for federal income tax purposes of $2.2 billion and state of $379 million.  The Company estimates it will need to 
generate future taxable income to fully realize the net federal deferred tax asset before expiration commencing in 2031. In addition, 
NRG has cumulative foreign NOL carryforwards of $62 million with no expiration date. 

        Valuation allowance — As of December 31, 2018, the Company's tax effected valuation allowance was $3.8 billion, consisting 
of domestic federal net deferred tax assets of approximately $3.3 billion, domestic state net deferred tax assets of $454 million, 
foreign NOL carryforwards of $62 million and foreign capital loss carryforwards of approximately $1 million. Based upon the 
assessment of cumulative and forecasted pretax book earnings, and the future reversal of existing taxable temporary differences, 
it was determined that a valuation allowance was required to be recorded during the year.

  Taxes Receivable and Payable

As of December 31, 2018, NRG recorded a current tax payable of $3 million that represents a tax liability due for state 
income taxes.  NRG has a tax receivable of $1 million, comprised of refunds due from state income tax estimated payments and 
return filings.

Uncertain tax benefits

NRG has identified uncertain tax benefits whose after-tax value is $26 million and $30 million, as of December 31, 2018
and 2017, for which NRG has recorded a non-current tax liability of $30 million and $33 million, respectively.  The Company 
recognizes interest and penalties related to uncertain tax benefits in income tax expense.  During the year ended December 31, 
2018, the Company recognized an expense of $1 million in interest.  As of December 31, 2018 and 2017, NRG had cumulative 
interest and penalties related to these uncertain tax benefits of $4 million and $3 million, respectively.

        Tax jurisdictions — NRG is subject to examination by taxing authorities for income tax returns filed in the U.S. federal 
jurisdiction and various state and foreign jurisdictions including operations located in Australia. 

The Company is no longer subject to U.S. federal income tax examinations for years prior to 2015.  With few exceptions, 

state and local income tax examinations are no longer open for years before 2010.

NRG Energy, Inc. Long-Term Incentive Plan

On April 27, 2017, the NRG LTIP was amended to increase the number of shares available for issuance by 3,000,000. As of 
December 31, 2018 and 2017, a total of 25,000,000 shares of NRG common stock were authorized for issuance under the NRG 
LTIP. There were 8,564,611 and 8,724,595 shares of common stock remaining available for grants under the NRG LTIP as of 
December 31, 2018 and 2017, respectively. The NRG LTIP is subject to adjustments in the event of reorganization, recapitalization, 
stock  split,  reverse  stock  split,  stock  dividend,  and  a  combination  of  shares,  merger  or  similar  change  in  NRG's  structure  or 
outstanding shares of common stock.

Upon adoption of the amended NRG LTIP effective April 27, 2017, no shares of NRG common stock remain available for 
future issuance under the NRG GenOn LTIP. As of December 31, 2018 and 2017, there were 520,182 and 1,369,880 shares of 
common stock remaining available for grants under the NRG GenOn LTIP, respectively.

Non-Qualified Stock Options

NRG  recognizes  compensation  costs  for  NQSOs  over  the  requisite  service  period  for  the  entire  award. The  maximum 

contractual term is 10 years for NRG's outstanding NQSOs. No NQSOs were granted in 2018, 2017 or 2016.

Restricted Stock Units

As of December 31, 2018, RSUs granted under the Company's LTIPs typically have three-year graded vesting schedules 
beginning on the grant date. Fair value of the RSUs is based on the closing price of NRG common stock on the date of grant.  The

Deferred Stock Units

DSUs represent the right of a participant to be paid one share of NRG common stock at the end of a deferral period established 
under the terms of the award. DSUs granted under the Company's LTIPs are fully vested at the date of issuance. Fair value of the 
DSUs, which is based on the closing price of NRG common stock on the date of grant, is recorded as compensation expense in 
the period of grant.

years ended December 31, 2018, 2017, and 2016 were $0 million, $4 million, and $1 million, respectively.  The weighted average 
grant date fair value of DSUs granted during the years ended December 31, 2018, 2017, and 2016 was $33.43, $16.76, and $16.85, 
respectively.

Performance Stock Units

PSUs entitle the recipient to stock upon vesting. The amount of the award is subject to the Company's achievement of certain 
performance measures over the vesting period. As of December 31, 2018, non-vested PSUs consist of Market Stock Units, or 
MSUs, and Relative Performance Stock Units, or RPSUs.

Relative Performance Stock Units — RPSUs are restricted grants where the quantity of shares increases and decreases 
alongside the Company's Total Shareholder Return, or TSR, relative to the TSR of the Company's current proxy peer group 
and the total returns of select indexes, or Peer Group. Each RPSU represents the potential to receive NRG common stock 
after the completion of the performance period, typically three years of service from the date of grant. The number of shares 
of NRG common stock to be paid (if any) as of the vesting date for each RPSU will depend on the Company’s percentile rank 
within the Peer Group. The number of shares of common stock to be paid as of the vesting date for each RPSU is linearly 
interpolated for TSR performance between the following points: (i) 0% if ranked below the 25th percentile; (ii) 25% if ranked 
at the 25th percentile; (iii) 100% if ranked at the 55th percentile (or the 65th percentile if the Company's absolute TSR is less 
than negative 15%); and (iv) 200% if ranked at the 75th percentile or above. The value of the common stock on the date of 
grant is based on the closing price of NRG common stock on the date of grant. 

Market Stock Units — MSUs are restricted grants where the quantity of shares increases and decreases alongside the 
Company's TSR. Each MSU represents the potential to receive NRG common stock after the completion of the performance 
period, typically three years of service from the date of grant. The number of shares of common stock to be paid as of the 
vesting date for each MSU is : (i) zero shares, if the TSR has decreased by more than 25% over the performance period, (ii) 
three-quarters of one share, if the TSR has decreased by 25% over the performance period; (iii) interpolated between three-
quarters of one share and one share, if the TSR has decreased less than 25% over the performance period; (iv) one share, if 
there is no change in TSR over the performance period; (v) interpolated between one share and two shares, if TSR increases 
less than 100% during the performance period; and (vi) two shares, if the TSR increases 100% over the performance period. 
The value of the common stock on the date of grant is based on the closing price of NRG common stock on the date of grant.
The Company last granted MSUs during the year ended December 31, 2016.

The fair value of PSUs is estimated on the date of grant using a Monte Carlo simulation model and expensed over the service 
period, which equals the vesting period. Significant assumptions used in the fair value model with respect to the Company's PSUs

Supplemental Information

The following table summarizes NRG's total compensation expense recognized for the years presented, as well as total non-
vested  compensation  costs  not  yet  recognized  and  the  period  over  which  this  expense  is  expected  to  be  recognized  as  of 
December 31, 2018, for each of the types of awards issued under the LTIPs. Minimum tax withholdings of $19 million, $5 million, 
and $5 million for the years ended December 31, 2018, 2017, and 2016, respectively, are reflected as a reduction to additional 
paid-in capital on the Company's consolidated balance sheets and are reflected as operating activities on the Company's consolidated 
statements of cash flows.

Gladstone — NRG provides services to Gladstone, an equity method investment, under an operations and maintenance 
agreement.  Fees for services under this contract primarily include recovery of NRG's costs of operating the plant, as approved in 
the annual budget, as well as a base monthly fee.

GenConn — NRG provides services to GenConn under operations and maintenance agreements with GenConn Devon and 
GenConn Middletown that began in June 2010 and June 2011, respectively. NRG no longer has an ownership interest in GenConn 
as a result of the sale of its ownership interests in NRG Yield, Inc. and its Renewables Platform.

Ivanpah — NRG provides services to Ivanpah, an equity method investment as of May 1, 2018, under an operations and 
maintenance agreement. Fees for the services under this contract primarily include recovery of NRG's costs of operating the plant 
plus a profit margin. 

Midway-Sunset —  NRG  provides  services  to  Midway-Sunset,  an  equity  method  investment,  under  an  operations  and 
maintenance agreement. Fees for the services under this contract primarily include recovery of NRG's costs of operating the plant, 
as approved in the annual budget, as well as a base monthly fee and an annual incentive bonus. 

Services Agreement and Transition Services Agreement with GenOn

 The Company provided GenOn with various management, personnel and other services, which include human resources, 
regulatory and public affairs, accounting, tax, legal, information systems, treasury, risk management, commercial operations, and 
asset management, as set forth in the services agreement with GenOn, or the Services Agreement. The annual fees under the 
Services Agreement was approximately $193 million and management had concluded that this method of charging overhead costs 
was reasonable. In connection with the Restructuring Support Agreement in 2017, NRG agreed to provide shared services to 
GenOn under the Services Agreement for an adjusted annualized fee of $84 million. 

In December 2017, in conjunction with the confirmation of the GenOn Entities' plan of reorganization, the Services Agreement 
was terminated and replaced by the transition services agreement. Under the transition services agreement, NRG provided the 
shared services and other separation services at an annualized rate of $84 million, subject to certain credits and adjustments. GenOn 
provided notice to NRG of its intent to terminate the transition services agreement effective August 15, 2018 and in connection 
with the settlement agreement described in Note 3, Acquisitions, Discontinued Operations and Dispositions, all amounts owed 
and payable to NRG were settled against the $28 million credit provided for in the Restructuring Support Agreement. For the year 
ended December 31, 2018, NRG recorded approximately $53 million, under the transition services agreement against selling, 
general and administrative expenses post-Chapter 11 Filing. For the year ended December 31, 2017, NRG recorded other income 
- affiliate related to these services of $87 million prior to the Chapter 11 Filing and $42 million against selling, general and 
administrative expenses post-Chapter 11 Filing. 

Credit Agreement with GenOn 

NRG and GenOn were party to a secured intercompany revolving credit agreement.  The intercompany revolving credit 
agreement provided for a $500 million revolving credit facility, all of which was available for revolving loans and letters of credit. 
As a result of the GenOn bankruptcy, no additional revolving loans or letters of credit were available to GenOn. As of  December 31, 
2017, $92 million of letters of credit were issued and outstanding. As a result of the GenOn Settlement, as further described in 
Note 3, Acquisitions, Discontinued Operations, and Dispositions, outstanding borrowings were repaid to NRG, except for certain 
LCs issued which are further discussed below. The facility was terminated on December 14, 2018.

On December 7, 2018, NRG, GenOn and REMA entered into an agreement to support the outstanding LCs from the 
intercompany revolving credit agreement previously issued. As of December 31, 2018,  $30 million was outstanding. GenOn 

177

 
 
 
 
 
 
and REMA have provided support for these outstanding LCs through back-to-back letters of credit and cash collateral. The 
outstanding letters of credit will continue to accrue any contractual fees and expenses until they are terminated.

Commercial Operations Agreement

NRG Power Marketing LLC has entered into physical and financial intercompany commodity and hedging transactions with 
GenOn and certain of its subsidiaries. Subject to applicable collateral thresholds, these arrangements may provide for the bilateral 
exchange  of  credit  support  based  upon  market  exposure  and  potential  market  movements.  The  terms  and  conditions  of  the 
agreements are generally consistent with industry practices and other third party arrangements. As of December 31, 2018, derivative 
assets  and  liabilities  associated  with  these  transactions  are  recorded  within  NRG's  derivative  instruments  balances  on  the 
consolidated  balance  sheet,  with  related  revenues  and  costs  within  operating  revenues  and  cost  of  operations,  respectively. 
Additionally, as of December 31, 2018 and December 31, 2017, the Company had $4 million and $32 million, respectively, of 
cash collateral posted in support of energy risk management activities by GenOn.

Note 21 — Commitments and Contingencies 

Operating Lease Commitments

Powerton and Joliet Leases

The Company leases 100% interests in the Powerton facility and Unit 7 and Unit 8 of the Joliet facility through 2034 and 
2030, respectively, through its indirect subsidiary, Midwest Generation, LLC.  The Company accounts for these leases as operating 
leases  and  records  lease  expense  on  a  straight-line  basis  over  the  lease  term.    In  connection  with  the  acquisition  of    Midwest 
Generation the Company recorded in 2014 the out-of-market value as a liability in out-of-market contracts of $159 million.  The 
liability will be amortized through rent expense on a straight-line basis over the term of the lease.  The Company expects to record 
lease expense, net of amortization of the out-of-market liability, of approximately $14 million per year through the term of the 
lease. This accounting will change effective January 1, 2019 upon the adoption of ASU 2016-02 as discussed further in Note 2, 
Summary of Significant Accounting Policies - Recent Accounting Developments - Guidance Not Yet Adopted.

NRG  leases  certain  Company  facilities  and  equipment  under  operating  leases,  some  of  which  include  escalation  clauses, 
expiring on various dates through 2036.  NRG also has certain tolling arrangements to purchase power, which qualify as operating 
leases.  Certain operating lease agreements include provisions such as scheduled rent increases, leasehold incentives, and rent 
concessions over their lease term.  The Company recognizes the effects of these scheduled rent increases, leasehold incentives, and 
rent  concessions  on  a  straight-line  basis  over  the  lease  term  unless  another  systematic  and  rational  allocation  basis  is  more 
representative of the time pattern in which the leased property is physically employed.  Lease expense under operating leases was 
$66 million, $69 million, and $85 million for the years ended December 31, 2018, 2017, and 2016, respectively.

NRG has granted first liens to certain counterparties on a substantial portion of the Company's assets, excluding assets acquired 
in the EME (including Midwest Generation) acquisitions, and NRG's assets that have project-level financing, to reduce the amount 
of cash collateral and letters of credit that it would otherwise be required to post from time to time to support its obligations under 
out-of-the-money hedge agreements for forward sales of power or MWh equivalents.  The Company's lien counterparties may have 
a claim on NRG's assets to the extent market prices exceed the hedged price.  As of December 31, 2018, hedges under the first lien 
were out-of-the-money for NRG on a counterparty aggregate basis.

Lignite Contract with Texas Westmoreland Coal Co.

       The Company's Limestone facility historically blended lignite obtained from the Jewett mine, which was operated by Texas 
Westmoreland Coal Co, or TWCC, and coal sourced from the Powder River Basin in Wyoming. On August 18, 2016, NRG gave 
notice to TWCC terminating the active mining of lignite under the contract, effective on December 31, 2016.  Under the contract, 
TWCC continues to be responsible for reclamation activities. NRG is responsible for reclamation costs and has recorded an adequate 
ARO liability. The Railroad Commission of Texas has imposed a bond obligation of approximately $99 million on TWCC for the 
reclamation of the mine. Pursuant to the contract with TWCC, NRG supports this obligation through surety bonds. Additionally, 
under  the  terms  of  the  contract,  NRG is  obligated  to  provide  additional  performance  assurance  if  required  by  the  Railroad 
Commission of Texas.

On October 9, 2018, TWCC and certain of its affiliates filed for protection under Chapter 11 of the U.S. Bankruptcy Code 
before the Bankruptcy Court for the Southern District of Texas.  TWCC has obtained authorization from the Bankruptcy Court to 
continue to perform its obligations under its contract with the Company and to maintain surety bond programs throughout its 
operations.  In addition, NRG has not received any indication from the Railroad Commission of Texas of an intent to draw on the 
surety bonds.  TWCC has filed a plan of reorganization that, if confirmed, would provide for the assumption and/or assignment of 
the contract with NRG.  Unless the Jewett mine and other related assets of TWCC are sold to another third party before the plan 
of reorganization is consummated, TWCC and/or its assets, including the Jewett mine and related agreements with NRG, will be 
owned upon the consummation of the plan by a new entity that is initially owned and controlled by certain holders of TWCC’s pre-
bankruptcy funded indebtedness.  The Bankruptcy Court is currently expected to consider confirmation of the plan in late February, 
unless adjourned to a later date.  However, given the uncertainty involved in bankruptcy proceedings, it is uncertain whether these 
transactions will be consummated and whether and to what extent TWCC’s bankruptcy may, in the future, impact the reclamation 
costs incurred by NRG or the surety bonds.  

Nuclear Insurance 

STP maintains required insurance coverage for liability claims arising from nuclear incidents pursuant to the Price-Anderson 
Act. Effective September 10, 2018, the current liability limit per incident is $14.07 billion, subject to change to account for the 
effects of inflation and the number of licensed reactors. An inflation adjustment must be made at least once every five years with 
the next due no later than September 10, 2023. Under the Price-Anderson Act, owners of nuclear power plants in the U.S. are 
required to purchase primary insurance limits of $450 million for each operating site. In addition, the Price-Anderson Act requires 
an additional layer of protection through mandatory participation in a retrospective rating plan for power reactors resulting in an 
additional $13.4 billion in funds available for public liability claims. The current maximum assessment per incident, per reactor, 
is approximately $138 million, taking into account a 5% adjustment for administrative fees, payable at approximately $21 million
per year, per reactor. NRG would be responsible for 44% of the maximum assessment, or $9 million per year, per reactor, and a 
maximum of $61 million per incident. In addition, the U.S. Congress retains the ability to impose additional financial requirements 
on the nuclear industry to pay liability claims that exceed $14 billion for a single incident. The liabilities of the co-owners of STP 
with respect to the retrospective premium assessments for nuclear liability insurance are joint and several.  

STP purchases insurance for property damage and site decontamination cleanup costs from Nuclear Electric Insurance Limited, 
or  NEIL,  and  European  Mutual Association  for  Nuclear  Insurance,  or  EMANI,  both  of  which  are  industry  mutual  insurance 
companies, of which STP is a member. STP has purchased $2.75 billion in limits for nuclear events and $1.5 billion in limits for 
non-nuclear events (the non-nuclear event limit is expected to reduce to $1.0 billion effective April 1, 2019). The nuclear event 
limit remains the maximum available from NEIL.  The upper $1.25 billion in limits (excess of the first $1.5 billion in limits) is a 
single limit blanket policy shared with two Diablo Canyon nuclear reactors, which have no affiliation with the Company.  This 
shared limit is not subject to automatic reinstatement in the event of a loss.  The NEIL policy covers both nuclear and non-nuclear 
property damage events, and a NEIL companion policy provides Accidental Outage coverage for the co-owners of STP's lost revenue 
following a property damage event, at a weekly indemnity limit of $3 million per unit up to a maximum of $274 million nuclear 
per unit and $184 million non-nuclear per unit, and is subject to an eight-week waiting period.  NRG also purchases an Accidental 
Outage  policy  from  NEIL,  which  provides  protection  for  lost  revenue  due  to  an  insurable  event.   This  coverage  allows  for 
reimbursement up to $1.98 million per week per unit up to a maximum of $216 million nuclear and $144 million non-nuclear, and 
is subject to an eight-week waiting period.  Under the terms of the NEIL and EMANI policies, member companies may be assessed 
up to ten and six times their annual premiums respectively if the NEIL or EMANI Board of Directors determines their surplus has 
been depleted due to the payment of property losses at any of the licensed reactors in a single policy year.  NEIL and EMANI  
require that their  members maintain an investment grade credit rating or insure their annual retrospective obligation by providing 
a financial guarantee, letter of credit, deposit premium, or an insurance policy.  NRG has purchased an insurance policy from NEIL 
and EMANI to guarantee the Company's obligation; however note the NEIL aspect of this insurance will only respond to retrospective 
premium adjustments assessed within twenty-four months after the policy term, whereas NEIL's Board of Directors can make such 
an adjustment up to 6 years after the policy expires.

Contingencies

The Company's material legal proceedings are described below.  The Company believes that it has valid defenses to these legal 
proceedings and intends to defend them vigorously.  NRG records reserves for estimated losses from contingencies when information 
available indicates that a loss is probable and the amount of the loss, or range of loss, can be reasonably estimated.  As applicable, 
the Company has established an adequate reserve for the matters discussed below. In addition, legal costs are expensed as incurred.  
Management has assessed each of the following matters based on current information and made a judgment concerning its potential 
outcome, considering the nature of the claim, the amount and nature of damages sought, and the probability of success.  Unless 
specified below, the Company is unable to predict the outcome of these legal proceedings or reasonably estimate the scope or 
amount of any associated costs and potential liabilities.  As additional information becomes available, management adjusts its 
assessment and estimates of such contingencies accordingly.  Because litigation is subject to inherent uncertainties and unfavorable 
rulings or developments, it is possible that the ultimate resolution of the Company's liabilities and contingencies could be at amounts 
that are different from its currently recorded reserves and that such difference could be material.

In addition to the legal proceedings noted below, NRG and its subsidiaries are party to other litigation or legal proceedings 
arising in the ordinary course of business.  In management's opinion, the disposition of these ordinary course matters will not 
materially adversely affect NRG's consolidated financial position, results of operations, or cash flows.

Midwest Generation Asbestos Liabilities — The Company, through its subsidiary, Midwest Generation, may be subject to 
potential asbestos liabilities as a result of its acquisition of EME.  The Company is currently analyzing the scope of potential liability 
as it may relate to Midwest Generation. The Company believes that it has established an adequate reserve for these cases.  On 
March 27, 2018, ComEd filed a Motion to Compel Payments of Claims seeking $61 million related to asbestos liabilities. On April 
25, 2018, NRG filed an Omnibus Objection to All Remaining Claims of ComEd and Exelon.  A trial before the Bankruptcy Court 
to determine the amount of ComEd’s claims is currently scheduled for April 10, 2019. 

California Department of Water Resources and San Diego Gas & Electric Company v. Sunrise Power Company LLC - On 
January 29, 2016, CDWR and SDG&E (plaintiffs) filed a lawsuit against Sunrise Power Company, along with NRG and Chevron 
Power Corporation (defendants).  In June 2001, CDWR and Sunrise entered into a 10-year PPA under which Sunrise would construct 
and operate a generating facility and provide power to CDWR.  At the time the PPA was entered into, Sunrise had a transportation 
services agreement, or TSA, to purchase natural gas from Kern River through April 30, 2018.  In August 2003, CDWR entered into 
an agreement with Sunrise and Kern River in which CDWR accepted assignment of the TSA through the term of the PPA.  After 
the PPA expired, Kern River demanded that any reassignment be to a party which met certain creditworthiness standards which 
Sunrise did not.  As such, the plaintiffs brought this lawsuit against the defendants alleging breach of contract, breach of covenant 
of good faith and fair dealing and improper distributions.  Plaintiffs generally claim damages of $1.2 million per month for the 
remaining 70 months of the TSA.  On April 20, 2016, the defendants filed objections in response to the plaintiffs' complaint.  The 
objections were granted on June 14, 2016; however, the plaintiffs were allowed to file amended complaints on July 1, 2016. On 
July 27, 2016, defendants filed objections to the amended complaints.  On November 18, 2016, the court sustained the objections 
and allowed plaintiffs another opportunity to file a second amended lawsuit which they did on January 13, 2017. On April 21, 2017, 
the court issued an order sustaining the objections without leave to amend. On July 14, 2017, plaintiffs filed a notice of appeal. On 
January 10, 2018, plaintiffs filed their opening appellate brief.  Defendants filed their opposition brief on April 10, 2018.  On May 
30, 2018, plaintiffs filed their reply brief.  The case is now waiting for the court of appeal to schedule oral argument.

Griffoul v. NRG Residential Solar Solutions - On February 28, 2017, plaintiffs, consisting of New Jersey residential solar 
customers, filed a purported class action lawsuit in New Jersey state court.  Plaintiffs allege violations of the New Jersey Consumer 
Fraud Action and Truth-in-Consumer Contracts, Warranty and Notice Act with regard to certain provisions of their residential solar 
contracts.  The plaintiffs seek damages and injunctive relief as to the proper allocation of the solar renewable energy credits. On 
June 6, 2017, the defendants filed a motion to compel arbitration or dismiss the lawsuit.  Plaintiffs filed their opposition on June 
29, 2017. On July 14, 2017, the court denied NRG's motion to compel arbitration or dismiss the case. On July 25, 2017, NRG filed 
a motion for reconsideration of the appeal, which the court denied. On August 22, 2017, NRG filed a notice of appeal.  After oral 
argument on April 24, 2018, the Appellate Division reversed the lower court on May 4, 2018, and ordered that the plaintiff must 
arbitrate their claims against NRG.  On May 23, 2018, the plaintiff filed a petition for certification with the Supreme Court of New 
Jersey seeking to overturn the Appellate Division ruling. On January 25, 2019, the Supreme Court denied plaintiff’s petition for 
certification.

Washington-St. Tammany and Claiborne Electric Cooperative v. LaGen - On June 28, 2017, plaintiffs Washington-St. Tammany 
Electric Cooperative, Inc. and Claiborne Electric Cooperative, Inc. filed a lawsuit against Louisiana Generating, L.L.C., or LaGen, 
in the United States District Court for the Middle District of Louisiana.  The plaintiffs claim breach of contract against LaGen for 
allegedly  improperly  charging  the  plaintiffs  for  costs  related  to  the  installation  and  maintenance  of  certain  pollution  control 
technology.  Plaintiffs seek damages for the alleged improper charges and a declaration as to which charges are proper under the 
contract. On September 14, 2017, the court issued a scheduling order setting this case for trial on October 21, 2019.  LaGen filed 

181

its answer and affirmative defenses on November 17, 2017.  On February 4, 2019, NRG sold the South Central Portfolio, including 
the entities subject to this litigation.  However, NRG has agreed to indemnify the purchaser for certain losses suffered in connection 
therewith.

GenOn Chapter 11 Cases - On June 14, 2017, the GenOn Entities filed voluntary petitions for relief under Chapter 11 of the 
Bankruptcy Code in the Bankruptcy Court. On December 12, 2017, the Bankruptcy Court entered an order confirming GenOn's 
Chapter 11 plan, which provides for, among other things, GenOn’s transition to a standalone enterprise.  GenOn's Chapter 11 plan 
became effective on December 14, 2018.

Note 22 — Regulatory Matters 

NRG operates in a highly regulated industry and is subject to regulation by various federal and state agencies. As such, NRG 
is affected by regulatory developments at both the federal and state levels and in the regions in which NRG operates. In addition, 
NRG is subject to the market rules, procedures, and protocols of the various ISO and RTO markets in which NRG participates. 
These  power  markets  are  subject  to  ongoing  legislative  and  regulatory  changes  that  may  impact  NRG's  wholesale  and  retail 
businesses.

In addition to the regulatory proceedings noted below, NRG and its subsidiaries are parties to other regulatory proceedings 
arising in the ordinary course of business or have other regulatory exposure. In management's opinion, the disposition of these 
ordinary course matters will not materially adversely affect NRG's consolidated financial position, results of operations, or cash 
flows.

Zero-Emission Credits for Nuclear Plants in Illinois and New York - In 2016, Illinois enacted a Zero Emission Credit, or 
ZEC, program for selected nuclear units in Illinois. In total, the program directs over $2.5 billion over ten years to two Exelon-
owned nuclear power plants in Illinois. That same year, the NYSPSC issued its Clean Energy Standard, or CES, which provides 
for ZECs which would provide more than $7.6 billion over 12 years in out-of-market subsidy payments to certain selected nuclear 
generating units in New York. These ZECs are out-of-market subsidies that threaten to artificially suppress market prices and 
interfere with the wholesale power market. NRG, along with other companies, filed complaints in the federal courts of Illinois 
and New York alleging that these state programs are preempted by federal law and in violation of the dormant commerce clause.  
These cases have proceeded through the federal district court as well as the federal appellate court in Illinois and New York, 
respectively. On January 7, 2019, NRG and its trade association filed a Petition for Writ of Certiorari  with the United States 
Supreme Court in both cases.

California Station Power - As the result of unfavorable final and non-appealable litigation, the Company has accrued a 
liability associated with consumption of station power at three of the Company’s power plants in California, after August 30, 
2010. In December 2017, subsidiaries of the Company entered into settlements with SCE for the liabilities associated with the 
Company's El Segundo and Long Beach facilities. The Company has established an appropriate reserve pending potential 
regulatory action by SDG&E regarding Encina.

        South Central  - On August 4, 2016, NRG received a document hold notice from FERC regarding conduct in the MISO 
and PJM markets. It required NRG to retain communications related to multiple generating units in the South Central region. 
Since sending the notice, FERC has been investigating potential violations of MISO rules involving bidding for the Big Cajun 
2 facility, as well as other aspects of NRG’s operations in MISO. FERC has the authority to require disgorgement of profits and 
to impose penalties and NRG retains any liability following the sale of the South Central Portfolio. We expect a preliminary 
finding from FERC by the second quarter of 2019.

ISO-NE - On February 5, 2019, FERC has informed the Company that it has made a preliminary finding that the 

Company violated FERC's market behavior rules in connection with offers made into the ISO-NE Forward Capacity Auction in 
2016.  The Company understands that FERC is concerned that the Company was inaccurate in its communications with the 
Market Monitor regarding the costs and risks associated with operating certain units in the forward timeframe.  Ultimately, the 
Company opted to withdraw the relevant bids prior to the auction in 2016.  The Company will be engaging in discussions with 
FERC regarding this matter.

Note 23 — Environmental Matters 

NRG is subject to a wide range of environmental laws in the development, construction, ownership and operation of projects. 
These laws generally require that governmental permits and approvals be obtained before construction and during operation of 
power plants. NRG is also subject to laws regarding the protection of wildlife, including migratory birds, eagles and threatened 
and endangered species. The electric generation industry has been facing requirements regarding GHGs, combustion byproducts, 
water discharge and use, and threatened and endangered species that have been put in place in recent years. However, under the 
current U.S. presidential administration, some of these rules are being reconsidered and reviewed. In general, future laws are 
expected to require the addition of emissions controls or other environmental controls or to impose certain restrictions on the 
operations of the Company's facilities, which could have a material effect on the Company's consolidated financial position, results 
of operations, or cash flows. Federal and state environmental laws generally have become more stringent over time, although this 
trend could slow or pause in the near term with respect to federal laws under the current U.S. presidential administration.

Air

On August 31, 2018, EPA proposed replacing the Clean Power Plan (CPP) rule, which sought to broadly regulate CO2
emissions from the power sector, with the Affordable Clean Energy (ACE) rule, which if finalized, would require states to develop 
plans to seek heat rate improvements from coal-fired EGUs. The Company believes that the ACE rule replacing the CPP rule 
would on balance be positive for its generation fleet.

In February 2012, the EPA promulgated standards (the MATS rule) to control emissions of HAPs from coal and oil-fired 
electric generating units. The rule established limits for mercury, non-mercury metals, certain organics and acid gases, which had 
to be met beginning in April 2015. In December 2018, the EPA proposed a finding that regulating HAPs was not "appropriate and 
necessary" because the costs far exceed the benefits. Nonetheless, the EPA proposed keeping the substantive requirements of the 
MATS rule. While NRG cannot predict the final outcome of this rulemaking, NRG believes that because it has already invested 
in pollution controls and cleaner technologies, the fleet is well-positioned to comply with the MATS rule.

Water

Once Through Cooling Regulation — In August 2014, the EPA finalized the regulation regarding the use of water for 

once through cooling at existing facilities to address impingement and entrainment concerns. NRG anticipates that more 
stringent requirements will be incorporated into some of its water discharge permits over the next several years as NPDES 
permits are renewed, the Company anticipates the cost of complying with these requirements to be immaterial.

Effluent Limitations Guidelines — In November 2015, the EPA revised the Effluent Limitations Guidelines for Steam Electric 
Generating Facilities, which would have imposed more stringent requirements (as individual permits were renewed) for wastewater 
streams from flue gas desulfurization, or FGD, fly ash, bottom ash, and flue gas mercury control.  In April 2017, the EPA granted 
two petitions to reconsider the rule and also administratively stayed some of the deadlines. On September 18, 2017, the EPA 
promulgated a final rule that (i) postpones the compliance dates to preserve the status quo for FGD wastewater and bottom ash 
transport water by two years to November 2020 until the EPA completes its next rulemaking and (ii) withdrew the April 2017 
administrative stay. The legal challenges have been suspended while the EPA reconsiders and likely modifies the rule. Accordingly, 
the Company has largely eliminated its estimate of the environmental capital expenditures that would have been required to comply 
with permits incorporating the revised guidelines. The Company will revisit these estimates after the rule is revised.  

Byproducts, Wastes, Hazardous Materials and Contamination

In April 2015, the EPA finalized the rule regulating byproducts of coal combustion (e.g., ash and gypsum) as solid wastes 
under the RCRA. In 2017, the EPA agreed to reconsider the rule.  On July 30, 2018, the EPA promulgated a rule that amends the 
existing ash rule by extending some of the deadlines and providing more flexibility for compliance.  On August 21, 2018, the D.C. 
Circuit found, among other things, that the EPA had not adequately regulated unlined ponds and legacy ponds.  Accordingly, we 
anticipate that the EPA will promulgate new regulations to address these issues (including compliance deadlines) as it reconsiders 
other aspects of the existing rule. The EPA has stated that it intends to further revise the rule. The Company will provide estimates 
of the cost of compliance after the rule is revised.

For further discussion of these matters, refer to Note 21, Commitments and Contingencies.

NRG and its subsidiaries enter into various contracts that include indemnification and guarantee provisions as a routine part 
of the Company's business activities. Examples of these contracts include asset purchases and sale agreements, commodity sale 
and purchase agreements, retail contracts, joint venture agreements, EPC agreements, operation and maintenance agreements, 
service agreements, settlement agreements, and other types of contractual agreements with vendors and other third parties, as well 
as affiliates.  These contracts generally indemnify the counterparty for tax, environmental liability, litigation and other matters, as 
well as breaches of representations, warranties and covenants set forth in these agreements. The Company is obligated with respect 
to customer deposits associated with the Company's retail businesses.  In some cases, NRG's maximum potential liability cannot 
be estimated, since the underlying agreements contain no limits on potential liability.  

The following table summarizes the maximum potential exposures that can be estimated for NRG's guarantees, indemnities, 

and other contingent liabilities by maturity:

(a)  As of December 31, 2017 excludes $92 million of letters of credit issued under the intercompany revolving credit agreement between NRG and GenOn 
(b)  December 31, 2018 includes $32 million of letter of credit and surety bonds for the benefit of GenOn where NRG holds cash or  letter of credit to back stop 

the liability

Letters of credit and surety bonds — As of December 31, 2018, NRG and its consolidated subsidiaries were contingently 
obligated for a total of $1.3 billion under letters of credit and surety bonds.  Most of these letters of credit and surety bonds are 
issued in support of the Company's obligations to perform under commodity agreements and obligations associated with future 
closure and maintenance of ash sites, as well as for financing or other arrangements.  A majority of these letters of credit and surety 
bonds expire within one year of issuance, and it is typical for the Company to renew them on similar terms.

The material indemnities, within the scope of ASC 460, are as follows:

Asset sales — The purchase and sale agreements which govern NRG's asset or share investments and divestitures customarily 
contain guarantees and indemnifications of the transaction to third parties.  The contracts indemnify the parties for liabilities 
incurred as a result of a breach of a representation or warranty by the indemnifying party, or as a result of a change in tax laws.  
These obligations generally have a discrete term and are intended to protect the parties against risks that are difficult to predict or 
estimate at the time of the transaction.  In several cases, the contract limits the liability of the indemnifier. NRG has no reason to 
believe  that  the  Company  currently  has  any  material  liability  relating  to  such  routine  indemnification  obligations,  except  as 
described in Note 3,  Acquisitions, Discontinued Operations and Dispositions.

Other guarantees — NRG has issued other guarantees of obligations including payments under certain agreements with 
respect to certain of its unconsolidated subsidiaries, payment or performance by fuel providers and payment or reimbursement of 
credit support and deposits. The Company does not believe that it will be required to perform under these guarantees.

184

 
 
 
 
 
 
 
Other  indemnities — Other  indemnifications  NRG  has  provided  cover  operational,  tax,  litigation  and  breaches  of 
representations, warranties and covenants.  NRG has also indemnified, on a routine basis in the ordinary course of business, 
consultants  or  other  vendors  who  have  provided  services  to  the  Company.    NRG's  maximum  potential  exposure  under  these 
indemnifications can range from a specified dollar amount to an indeterminate amount, depending on the nature of the transaction.  
Total maximum potential exposure under these indemnifications is not estimable due to uncertainty as to whether claims will be 
made or how they will be resolved.  NRG does not have any reason to believe that the Company will be required to make any 
material payments under these indemnity provisions.

Because many of the guarantees and indemnities NRG issues to third parties and affiliates do not limit the amount or duration 
of its obligations to perform under them, there exists a risk that the Company may have obligations in excess of the amounts 
described above.  For those guarantees and indemnities that do not limit the Company's liability exposure, it may not be able to 
estimate what the Company's liability would be, until a claim is made for payment or performance, due to the contingent nature 
of these contracts.

Note 26 — Jointly Owned Plants  

Certain NRG subsidiaries own undivided interests in jointly-owned plants, as described below.  These plants are maintained 
and operated pursuant to their joint ownership participation and operating agreements.  NRG is responsible for its subsidiaries' 
share of operating costs and direct expenses and includes its proportionate share of the facilities and related revenues and direct 
expenses  in  these  jointly-owned  plants  in  the  corresponding  balance  sheet  and  income  statement  captions  of  the  Company's 
consolidated financial statements. 

The following table summarizes NRG's proportionate ownership interest in the Company's jointly-owned facilities:

The non-guarantor subsidiaries include all of NRG's foreign subsidiaries and certain domestic subsidiaries.  NRG conducts 
much of its business through and derives much of its income from its subsidiaries.  Therefore, the Company's ability to make 
required payments with respect to its indebtedness and other obligations depends on the financial results and condition of its 
subsidiaries and NRG's ability to receive funds from its subsidiaries.  Except for NRG Bayou Cove, LLC, which is subject to 
certain restrictions under the Company's Peaker financing agreements, there are no restrictions on the ability of any of the guarantor 
subsidiaries to transfer funds to NRG.  In addition, there may be restrictions for certain non-guarantor subsidiaries.

The following condensed consolidating financial information presents the financial information of NRG Energy, Inc., the 
guarantor subsidiaries and the non-guarantor subsidiaries in accordance with Rule 3-10 under the SEC's Regulation S-X.  The 
financial information may not necessarily be indicative of results of operations or financial position had the guarantor subsidiaries 
or non-guarantor subsidiaries operated as independent entities.

In this presentation, NRG Energy, Inc. consists of parent company operations. Guarantor subsidiaries and non-guarantor 
subsidiaries of NRG are reported on an equity basis.  For companies acquired, the fair values of the assets and liabilities acquired 
have been presented on a push-down accounting basis.

In addition, the condensed parent company financial statements are provided in accordance with Rule 12-04, Schedule I of 
Regulation S-X, as the restricted net assets of NRG Energy, Inc.'s subsidiaries exceed 25 percent of the consolidated net assets of 
NRG Energy, Inc.  These statements should be read in conjunction with the consolidated statements and notes thereto of NRG 
Energy, Inc.  For a discussion of NRG Energy, Inc.'s long-term debt, see Note 11, Debt and Capital Leases, to the consolidated 
financial statements.  For a discussion of NRG Energy, Inc.'s contingencies, see Note 21, Commitments and Contingencies, to the
