1999 was quite a year. Once again, we fulfilled our promises, delivered on

expectations, and proved that we have earned and deserve the acclaim we receive

as a leading, energy growth company.

Our earnings grew by 35 percent, ending the year at 37 cents per Northern States

Power Company (NSP) share. We added 7,690 net equity megawatts to our portfolio,

an astounding 233 percent growth rate. New acquisitions in 1999, added to our exist-

ing asset base in the United States, Europe, Australia and Latin America, brought us to

nearly 11,000 megawatts of net ownership and more than 23,000 megawatts of

installed generating capacity. We will complete the acquisition of at least 4,248 net

equity megawatts in 2000.

How did we do it? Three basic tenets support our global activities: smart growth, market-

focused strategies, and a relentless drive to deliver increasing value to our shareholder.

We identified opportunities that fit our product mix and operating strategy, bought at the

right price and closed those deals on a timely basis. Our expertise at improving and

operating power plants kept our generating assets ready to meet market demands. The

combination of our extensive market knowledge and very high plant availability allowed

us to meet and, in many cases, exceed our net revenue goals. In all markets, national

and international, our objective with all assets and activities is to make decisions and take

actions that will maximize value for our shareholder, our employees and our communities.

North America dominated our activities during the year. We completed purchases in

New York, Massachusetts, Connecticut and Southern California, and we were

confirmed as the winning bidder for the 1,708 megawatts of fossil-fueled assets of

Louisiana-based Cajun Electric Power Cooperative. In January 2000, we signed an

agreement to acquire 1,875 megawatts of assets located in four states from Conectiv of

Wilmington, Delaware. We opened business offices in San Diego, California and

Pittsburgh, Pennsylvania.

NRG Energy, Inc. 1999 Annual Report | Letter to Shareholder | “Our rapid

growth has added significant value to the company by raising our visibility

within the industry and positioning us for continued high rates of earnings

growth.” David H. Peterson, Chairman, President and Chief Executive Officer,

NRG Energy, Inc.

In Europe, we signed a purchase agreement to acquire the 665 megawatt Killingholme A

Station from National Power plc in the United Kingdom. We won the bid for a 600

megawatt plant in Turkey, and we opened a development office in Warsaw, Poland.

In the United States, we are among the top three Northeast independent generators and

the top three companies in district heating and cooling, refuse-derived fuel and landfill gas

generation. In partnership with Dynegy Inc., we are among the top four West Coast inde-

pendent generators. Also, we are the largest independent power producer in Australia.

We reduced our ownership in CogenAmerica from 45 percent to 20 percent by selling

a portion of our interest to Calpine Corporation. When we purchased Cogen’s prede-

cessor, O’Brien Environmental Energy, in early 1996, the company was bankrupt and

valued by the Court at approximately $7.50 per share. Based on the $25.00 price for

the sale to Calpine, the shares have appreciated by more than 40 percent annually.

Our rapid growth has added significant value to the company by raising our visibility

within the industry and positioning us for continued high rates of earnings growth.

Customers and partners are seeking us out for new projects. And the mix of our

assets— from electric power generation utilizing coal, natural gas, landfill gas, oil, hydro

and biomass, to district heating and cooling and refuse-derived fuel—positions us as a

unique, expert generation company in additional markets, for many more opportunities.

We have garnered recognition as a “must watch” energy growth company from many

in the investment community during the last three years. They see a team that has

built an attractive, diverse, global portfolio; a development machine that acts strategi-

cally and tenaciously; a solid reputation as an operator that can predict and achieve

profitability from its assets; and an enviable position as the seventh largest independent

power producer in the world. We have established the momentum that will sustain our

growth and profitability in the years to come.

“We have garnered recognition as a ‘must watch’ energy growth company from

many in the investment community during the last three years.” David H.

Peterson, Chairman, President and Chief Executive Officer, NRG Energy, Inc.

To focus our ongoing initiatives, we have developed three primary financial objectives:

increase earnings by at least 25 percent annually; improve our investment grade bond

rating; and earn a premium return for our shareholder, Northern States Power Company.

NSP has supported us financially since our beginning in 1989 and has helped enable

the success we realize today.

I’ve said often that this is a remarkable company. In 1999, many other people, inside

and outside our company, also were impressed by our achievements. They sang our

praises at our 10th anniversary events in the United States, Australia and the Czech

Republic. This report captures some of those comments and shares them with you.

My personal thanks to each of our employees and our partners for their smart and

determined work. My thanks to NSP for its strong financial and moral support over

the last 10 years. We will work hard to sustain our place among the top 10 global

power generators. And we will succeed again in the year 2000 and beyond.

David H. Peterson

NRG Energy, Inc. 1999 Annual Report | Power Generation Facilities

NRG Energy, Inc. 1999 Annual Report | Growth | “I believe that the reason

NRG has been successful is because of our determination. We have never

given up. We have been very fair—and we’ve been very lucky. But often-

times, we have made our own luck.” Michael Carroll, President, NRG

Thermal “Your accomplishments in the energy industry, or in any industry

for that matter, are formidable. Your successful entry and development of

difficult international markets and your ability to seize domestic divestiture

opportunities have made you a leader worldwide in the independent power

production market.” Bill Richardson, United States Secretary of Energy “ I think

the best years are certainly ahead for NRG.” James J. Howard, Chairman,

President and Chief Executive Officer, Northern States Power Company “NRG is

now a very significant entity in its own right and it will be very important

that NRG continue to have the appropriate infrastructure from which to

continue to grow but still keep the discipline and the hands-on approach that

has helped it to achieve its success to-date.” Edward J. McIntyre, Vice President

and Chief Financial Officer, Northern States Power Company “ We do things in

a matter of weeks that it takes a number of companies months to do. If you’re

not going to be able to have the ability to function that quickly and effi-

ciently, you may as well get out of the business. I think other people in the

industry are doing it too. It’s necessary to compete.” James J. Bender, Vice

President, General Counsel and Corporate Secretary, NRG Energy, Inc.

Acquisitions in the Northeastern United

States were largely responsible for an

increase in operating revenue of 175

percent from 1998 to 1999.

In 1999 we grew in earnings, in megawatts and in reputation.

Earnings grew by 35 percent to 37 cents per NSP share, giving

NRG Energy an average earnings growth rate of 35 percent per year

since 1996. By the end of the year, in 15 countries, on four continents,

we had 176 facilities in operation, under construction or with signed

acquisition agreements. Our net equity in megawatts grew by a

remarkable 233 percent, garnering NRG Energy a place among the

world’s top 10 independent power generation companies in size and

annual growth rate.

Our 1999 earnings were enhanced by a combination of factors that

allowed us to capture maximum returns from newly acquired assets.

We acted quickly to seize growth opportunities around the world and

particularly in the United States. As divestitures continued to unfold

in California, restructuring and divestitures emerged in the Northeast.

Opportunities to build or acquire opened in Europe, as well.

We bought at prices that should allow us to earn premium returns.

Our skilled development teams swiftly completed transactions and

operational transitions, giving us increased earnings from operations.

Our newly acquired assets in the Northeastern United States per-

formed well throughout the summer of 1999, delivering excellent

returns during this critical operating period.

We acquired 1,218 megawatts of power generation facilities in

Southern California. Added to our purchases there in 1998, we

now own a 50 percent interest in 2,768 megawatts of capacity.

With our partner, Dynegy Inc., we have become one of the top

four independent power producers in that region.

Income from plant operations has grown

significantly over the past five years.

NRG Energy, Inc. 1999 Annual Report | Growth | “What has been accom-

plished at NRG in just 10 years has been nothing short of remarkable. NRG

has become a global powerhouse in power around the world. Energy production

is vital to our growth here in the United States and around the world.

Everything starts with energy. As we become more involved in the global

marketplace, companies such as NRG will lead the way.” Rod Grams, United

States Senator from Minnesota

In the Northeastern United States, with 100 percent interest in

nearly 7,000 megawatts of generation acquired from four utilities,

we have become one of the top three independent power producers.

Our current portfolio consists of 1,456 megawatts of generation

acquired from Consolidated Edison in New York; 2,235 megawatts

of generation acquired from Connecticut Light & Power; more than

3,000 megawatts acquired from Niagara Mohawk; and 229 megawatts

of generation acquired from Eastern Utility Associates in

Massachusetts. In January 2000, we executed an agreement to

acquire 1,875 megawatts of fossil-fueled generation and other assets

in four states from Conectiv of Delaware. We expect to complete

the purchase in late 2000.

In Louisiana, we were confirmed as the winning bidder for Cajun

Electric Power Cooperative’s 1,708 megawatts of fossil-fueled gener-

ation, opening new opportunities for growth in the South Central

United States. Cajun produces and sells electricity to three off-system

customers and 11 distribution cooperatives which deliver power to

more than one million people in Louisiana. This purchase will close

in the spring of 2000.

Winning Cajun was a tribute to our tenaciousness and our growth

strategy of leveraging our expertise in restructuring financially dis-

tressed projects. Cajun had sought bankruptcy protection in 1994

because of financial problems related to a nuclear plant investment.

For more than four years, we worked with the bankruptcy courts

and regulators to develop the final plans to own and operate the

fossil-fueled facilities of Cajun.

Our development activities in the United States also included

greenfield opportunities. With partners, Salt River Project and

Dynegy Inc., we announced plans to develop an 825 megawatt, natural

gas-fired, combined-cycle generating facility to serve the growing

demand for electricity in the greater Phoenix area. Final negotiations

on project agreements are in progress, and site permitting has begun.

Similarly, greenfield development is underway in Minnesota where

we and partner Tenaska, Inc. have received approval for a Certificate

of Need to build a 550 megawatt peaking facility.

Strategic development and growth opportunities continue for us

around the world. In Europe, we opened a development office in

Warsaw, Poland—adding to our active development offices in

London, Prague, Berlin, Tallinn and Istanbul.

We and our partners were selected as winning bidder for the 600

megawatt Seyitömer Power Station in Küthya, Turkey. Seyitömer is

our second successful bid in Turkey. In 1998, also with partners, we

won a bid to acquire the 450 megawatt coal-fired Kangal plant in

central Turkey. Our strategy is to build a long-term position in the

high-growth energy market in Turkey.

In the United Kingdom, our project partnership continued building

Enfield Energy Centre, a 396 megawatt, combined-cycle merchant

plant in North London. We expect Enfield to begin commercial

operations in the first half of 2000.

Our net income grew by 37 percent from

1998 to 1999.

NRG Energy, Inc. 1999 Annual Report | Growth | “NRG’s growth in the

Northeastern United States is the result of a focused team working together

to provide increased shareholder value by manufacturing reliable, efficient,

clean, electric energy.” Bryan Riley, Vice President, NRG North America

Eastern Region

Expanding our presence in the United Kingdom, we announced

plans to acquire Killingholme A, a 665 megawatt, gas-fired, combined-

cycle power station, from National Power plc. Also, we are negotiating

the purchase of National Power’s Blyth generating facilities, two

coal-fired stations totaling 1,140 megawatts of generation capacity.

And we are developing Langage Energy Park, an 800 megawatt

gas-fired, combined-cycle, greenfield merchant plant located near

Plymouth, England.

In Australia in 1999, our development team in Brisbane moved into

new offices to better manage the increasing development activities

in our Asia-Pacific region. We are the largest independent power

producer in Australia and have ownership and operational interests

in 4,072 megawatts of generation.

In Latin America, we have ownership and operational interests in

more than 1,110 megawatts of generation. In January 2000, with

our partner, Vattenfall AB, we took direct control of the South

American power development activities, previously conducted

through our jointly owned company, Cobee Energy Development

LLC. The new management approach allows us to streamline and

focus our companies’ development efforts around our regional base

at COBEE Bolivia. COBEE is the second largest generating company

in Bolivia.

COBEE and Pan American Energy LLC are nearing completion of

the Bulo Bulo project near Cochabamba, Bolivia. This 87megawatt

natural gas-fired generator is scheduled for a May 2000 in-service date.

Constantly paying attention to where we grow and how we grow is

key to our success. Smart strategic planning and project develop-

ment helped us win top positions in high growth, national and

international markets. Our expertise and performance in diverse

fuels, refurbishing assets, greenfield development, superior operations,

and power marketing drive profitability and make us attractive to

customers and partners. Our tenacious determination to grow

profitability has become more than a goal. It is an expectation of

each and every employee.

NRG Energy, Inc. 1999 Annual Report | Strategy | “We’ve got a very fine

crew here, probably one of the best strategic plans we’ve ever had as well

as an implementation plan. And so the company gets stronger every year.”

David H. Peterson, Chairman, President and Chief Executive Officer, NRG

Energy, Inc. “ For me, NRG is innovative. It’s exciting. And I think one

of the qualities that distinguish us from the other developers in the world

is that we’re very persistent.” Robert Brown, Vice President and Managing

Director, Western Europe, NRG Energy, Ltd. “I am proud of the ties that have

been developed between the Czech Republic and NRG during the last few

years. After so many years of Communist oppression and Marxist economy,

we terribly needed to open the country to foreign investment. NRG was

among the first American companies that came to my country to start

to do business. NRG was a very young company, filled with activity and

dynamics, and it was just what was needed in my country.” Alexandr

Vondra, Ambassador of the Czech Republic to the United States “ The folks

that I’ve talked to at the power plants we’ve recently acquired in New York

are very excited to be part of the NRG team because they’ve heard what

we’re doing in Europe, in Australia, in South America and—where they’ve

been part of a hometown utility—now they’re part of a global player.”

Louis P. Matis, Vice President, Corporate Operating Services, NRG Energy, Inc.

NRG’s vision is to be a well-positioned, top three generator in

selected markets. Our rapid growth in the United States from

1998 through 1999 was accomplished by focusing on five strategic

objectives: 1) maintain a base level of contract support; 2) offer

a broad set of energy products; 3) maintain a diverse fuel mix;

4) build market presence within specific markets; and 5) leverage

opportunities for sales to adjacent markets.

This strategic approach allows us to maintain a portfolio of assets

offering a variety of energy and capacity products, from baseload to

higher valued ancillary products, and it provides the scale and

flexibility we require to maximize each product’s value in the

marketplace. Expertise in asset management, operations and power

marketing also comes together at NRG Energy to create a synergistic

team approach that enhances value from operations. In 1999, we

concentrated as much on operational and sales excellence as we

did on growth strategies.

Our development teams identified the right acquisition opportunities,

offered competitive bids and completed purchases quickly to capture

additional revenues. Our experienced team of plant managers, asset

managers and fuel and power marketers worked together to deliver

exceptional operational and financial performance from our growing

generation portfolio.

Key to our 1999 success was our project developers’ and senior

managers’ ability to define each facility’s operating strategy and

direction, and accurately match the appropriate level of investment in

each facility to its operating expectations. Our asset managers played a

decisive role in defining optimum plant readiness and product delivery.

At the end of 1999, NRG had interests

in generating facilities representing

23,102 megawatts, including projects

under construction and under signed

acquisition agreements.

We fostered a global network of plant management that is unique

to the independent power industry. Our plant managers in all of our

operations shared resources, expertise and experiences in engineering,

environmental and operating issues. We reaped ongoing benefits as

our managers used their accumulated knowledge to apply a rich set

of solutions to operating challenges that arose throughout the year.

In October 1999, we held our first International Plant Managers

Conference, bringing together leaders from our operations on three

continents for two days of information sharing and direction setting.

Meetings like this are invaluable in solidifying a team approach to

problem solving and enhancing our operating and financial

performance worldwide.

NRG maintains a well-balanced fuel mix

with multiple fuel capabilities at many of

its generating stations. This approach helps

to mitigate the impact on NRG’s operations

from price volatility in the fuel markets.

NRG Energy, Inc. 1999 Annual Report | Strategy | “We’ve done things

differently than others. We have gone out and we have been, to some extent,

in the right place at the right time. We have taken advantage of some of the

less marquee deals and focused on some of the deals that maybe didn’t look

as pretty but are going to be just as profitable at the end of the day.” Craig A.

to any need kept our generating assets on-line and ready to meet

market demands. To that end, we worked hard to build strong

bonds between our plants and the power marketing function. We

moved quickly to develop our in-house power marketing skills and

solidify partnerships with power marketing companies. The operating

and marketing relationship is one of the most important variables to

increasing revenues, reducing costs and improving margins.

Our teamwork paid off, particularly in the Northeastern United

States where our power marketers worked closely with the plants

and asset managers to deliver returns beyond our expectations.

Dealing with evolving wholesale generation markets, our marketing

partner in California and our in-house power marketers in the

Northeast skillfully met the challenges of change as their regions

adjusted to the new ways of producing and selling energy.

Around the world, our operations performed well. In Australia,

Gladstone, Collinsville and Loy Yang kept up their track records of

efficient, environmentally sensitive and safe operations. In Germany,

Schkopau and MIBRAG performed well—MIBRAG delivering better

results with more coal sales and lower operating costs. In the Czech

Republic, Energy Center Kladno’s (ECK) refurbished facility met

expectations and our 345 megawatt expansion, ECK Generating

(ECKG), entered its last phase of construction.

In the United States, our businesses in thermal heating and cooling,

landfill gas generation and refuse-derived fuel continue to be unique

parts of our growth and our operating strategies. They give us a

strong competitive profile as a company interested in large and small

generation projects, as a company expert in traditional and non-

traditional energy sources, and as a company with expertise in

environmentally sound energy alternatives. These operations continue

to meet and exceed our goals and increase earnings.

Each part of our business must operate well. Also, each part must

cooperate, sharing strategy and expertise. With cooperation, maxi-

mizing the synergy within our operations, we derive greater benefits

and drive greater value to our bottom line.

We measure value in every part of our business. Smart, strategic

planning and development; reliable, efficient, safe operations;

improved environmental performance and effective power

marketing—all deliver value to our employees, our customers

and the communities in which we operate. And the bottom line

to all of this is value to the investor—our shareholder—with

earnings that are meeting our objectives today and a business

that will meet and exceed expectations for years to come.

We have earned our reputation as a company to watch. Our growth

in earnings is as impressive as our growth in megawatts, delivering

high value to our shareholder.

Our goal is to achieve 25 percent annual earnings growth for the

foreseeable future—a distinguishing characteristic of a high growth

company. Since 1996 our earnings have increased by an average rate

of 35 percent per year. Considering all of the projects we have initi-

ated in 1998 and 1999, we expect to make an even more significant

contribution to NSP earnings per share in 2000. Those projects

include: a full year of earnings from our assets in the Northeast; a

full year from Killingholme A and more than six months of earnings

from Enfield Energy Centre, both in the United Kingdom; and

several months from Cajun in Louisiana, an acquisition we expect to

complete in spring 2000. Also, we expect this year to complete the

acquisitions of the Narva Power Stations in Estonia as well as Kangal

and Seyitömer in Turkey.

Another dimension of value involves what we accomplish for our

customers, our employees and the communities where we operate.

We have developed a globally-renowned reputation for refurbishing

assets to operate efficiently and improve environmental performance.

Our work at ECK exemplifies the value this has for countries,

businesses, employees and communities. Located near Prague, ECK

is the first project-financed, independent power project in Central

Europe. It is a facility that provides electricity and district heating

to the town and adjacent industry.

Consistent with our goal of maintaining a

balanced portfolio of generation assets,

NRG’s facilities are 40 percent baseload, 20

percent intermediate and 40 percent peaking.

In 1999 we entered the last phase of construction of ECKG, the 345

megawatt expansion of the facility. The construction follows on the

heels of our work refurbishing the old facility to improve operations

and produce electricity more efficiently and more cleanly. We

replaced two coal-fired boilers having no sulfur dioxide or nitrogen

oxide controls with fluidized bed combustion boilers and other

environmental equipment that substantially improved environmental

performance. Also, we offered employee benefits to workers who

had few benefits when the plants were state-owned.

In February 2000, we announced a five-year plan to purchase 11

gas turbine generators and five steam turbine generators. The purchase

supports our strategy of acquiring facilities that offer an existing

earnings base and possess opportunities for future upgrades and

expansion. The turbines will deliver clean environmental perform-

ance and will have among the highest operating efficiencies of any

commercially available technology. We will deploy these turbines as

economic projections dictate at brownfield or greenfield sites in our

key regions.

Our expertise in diverse, environmentally responsible fuels and

operations also drives value to our bottom line, makes us an attractive

energy producer to potential partners and customers, and stimulates

our continued growth.

With ownership interests in four refuse-derived fuel (RDF) facilities

in Minnesota and Maine that process more than one million tons of

waste per year, we are the second largest producer of RDF in the

United States.

Our subsidiary, NRG Thermal is among the top three district heat-

ing and cooling providers in the United States with operations in

five states: California, Minnesota, North Dakota, Pennsylvania

and Washington.

In 1999, NRG Thermal purchased the remaining half ownership

of interest in district heating facilities in Pittsburgh and San Francisco,

becoming sole owner and operator. Growth continues as it adds

service to new buildings in those cities as well as in San Diego. In

Pennsylvania, the company was selected to purchase Harrisburg Steam

Works, Ltd., a regulated utility providing steam to approximately

300 customers, including the downtown and state capitol complex.

NRG Thermal expects to close on this purchase in spring 2000.

NEO, our renewable energy subsidiary, is one of the top three

United States landfill gas generation companies, extracting methane

from landfills to generate electricity. NEO owns 27 landfill gas oper-

ations around the country, has three new facilities under construction

and owns 18 hydro facilities.

Employee safety simply cannot be compromised. It is a value that

permeates all of our operations. When we assume plant operations,

we implement structured, disciplined safety programs from the

plant manager on down. As a result, the frequency and severity of

accidents in our plants have dropped, sometimes dramatically. In

the last four years, while our employee count around the world has

increased, our record of safe performance has held firm.

We value our reputation as a company that operates with integrity

and ethics and fulfills its promises. We have implemented tough

environmental standards of operation that apply to every employee.

Each and every one is called upon to report environmental violations,

and we do—even at times when we are not required to report— to

help ensure trust in our operations. Similarly, in 1999 we implemented

a corporate compliance program to ensure that each employee

understands and practices the highest ethical standards we demand

around the world.

NRG Energy, Inc. 1999 Annual Report | Value | “The greatest thing is the

opportunity to contribute to some of the greatest changes in economic

conditions that have taken place in the last 50 or 60 years. When we work in

some areas, such as Estonia, Germany and the Czech Republic, we’re able to

participate in and contribute to the complete restructuring of an economy.”

Gary H. Boline, Executive Director Operations, Europe, NRG Energy, Inc.

Delivering value demands much from all of us. It demands people

who have worked hard, with personal sacrifice, to earn all that we

have achieved—people who can celebrate success yet not grow com-

placent with it. Every day it demands one’s personal best in market

savvy, discipline, drive, energy and integrity. Our vision is a constant

one: to sustain the momentum and continue to be, simply, remarkable.

1N O T E O N E Organization

NRG Energy, Inc. (the Company), a Delaware corporation, was incorporated on May 29, 1992 as a wholly

owned subsidiary of Northern States Power Company (NSP). Beginning in 1989, the Company was doing

business through its predecessor companies NRG Energy, Inc. and NRG Group, Inc., Minnesota corpora-

tions which were merged into the Company subsequent to its incorporation. The Company and its

subsidiaries and affiliates develop, build, acquire, own and operate nonregulated energy-related businesses.

N O T E T W O Summary of Significant Accounting Policies

Principles of Consolidation and Basis of Presentation | The consolidated financial statements include the

accounts of the Company and its subsidiaries (referred to collectively herein as NRG). Accounting policies

for all of NRG operations are in accordance with accounting principles generally accepted in the United

States. All significant intercompany transactions and balances have been eliminated in consolidation.

NRG has investments in partnerships, joint ventures and projects for which the equity method of account-

ing is applied. Earnings from equity in international investments are recorded net of foreign income taxes.

Property, Plant and Equipment | Property, plant and equipment are capitalized at original cost.

Significant additions or improvements extending asset lives are capitalized, while repairs and maintenance

are charged to expense as incurred. Depreciation is computed using the straight-line method over the

following estimated useful lives:

Facilities and improvements 10 – 45 years

Machinery and equipment 7 – 30 years

Office furnishings and equipment 3 – 5 years

Development Costs and Capitalized Project Costs | These costs include professional services, dedicated

employee salaries, permits, and other costs which are incurred incidental to a particular project. Such costs

are expensed as incurred until a sales agreement or letter of intent is signed, and the project has been

approved by NRG’s Board of Directors. Additional costs incurred after this point are capitalized. When

project operations begin, previously capitalized project costs are reclassified to investment in projects and

amortized on a straight-line basis over the lesser of the life of the project’s related assets or revenue

contract period.

Intangibles | Intangibles consist principally of the excess of the cost of investment in subsidiaries over the

underlying fair value of the net assets acquired and are being amortized using the straight-line method

over 20 to 30 years. The Company periodically evaluates the recovery of goodwill and other intangibles

based on an analysis of estimated undiscounted future cash flows.

Other Long-Term Assets | Other long-term assets consist primarily of service agreements and operating

contracts. These assets are being amortized over the remaining terms of the individual contracts, which

range from 7 to 28 years.

Income Taxes | The Company is included in the consolidated tax returns of NSP. NRG calculates its

income tax provision on a separate return basis under a tax sharing agreement with NSP. Current federal

and state income taxes are payable to or receivable from NSP. NRG records income taxes using the liabil-

ity method. Income taxes are deferred on all temporary differences between pretax financial and taxable

income and between the book and tax bases of assets and liabilities. Deferred taxes are recorded using the

tax rates scheduled by law to be in effect when the temporary differences reverse.

Revenue Recognition | Under fixed-price contracts, revenues are recognized as products or services are

delivered. Revenues and related costs under cost reimbursable contract provisions are recorded as costs are

incurred. Anticipated future losses on contracts are charged against income when identified.

Foreign Currency Translation | The local currencies are generally the functional currency of NRG’s for-

eign operations. Foreign currency denominated assets and liabilities are translated at end-of-period rates

of exchange. The resulting currency adjustments are accumulated and reported as a separate component

of stockholder’s equity. Income, expense, and cash flows are translated at weighted-average rates of

exchange for the period.

Derivative Financial Instruments | Hedge Accounting is applied only if the derivative reduces the risk of

the underlying hedged item and is designated at inception as a hedge, with respect to the hedged item.

If a derivative instrument ceased to meet the criteria for deferral, any gains or losses would be currently

recognized in income. NRG does not hold or issue derivative financial instruments for trading purposes.

Reclassifications | Certain prior-year amounts have been reclassified for comparative purposes. These

reclassifications had no effect on net income or stockholder’s equity as previously reported.

N O T E T H R E E Business Acquisitions and Divestitures

In February 1999, NRG purchased from Thermal Ventures, Inc. (TVI) the remaining 50.1 percent limited

partnership interests held by TVI in San Francisco Thermal Limited Partnership and Pittsburgh Thermal

Limited Partnership for $12.3 million. In April 1999, NRG acquired TVI’s 50 percent member interest

in North American Thermal Systems LLC (the entity holding the general partnership interest in the San

Francisco and Pittsburgh partnerships) for $500,000.

In 1994, NRG, through a wholly owned subsidiary, purchased a 50 percent interest in Sunnyside

Generation Associates, which owns and operates a 58 megawatt waste coal plant in Utah. In March 1999,

NRG and its partner executed an agreement to sell the Sunnyside project to an affiliate of Baltimore Gas

& Electric for a purchase price of $2.0 million. There was no gain or loss on the sale which closed during

the second quarter of 1999.

In April 1999, NRG completed the acquisition of the Somerset power station for approximately $55 million

from the Eastern Utilities Association. The Somerset station, located in Somerset, Massachusetts, includes two

coal-fired generating facilities and two aeroderivative combustion turbine peaking units with a capacity

rating of 160 megawatts, excluding 69 megawatts on deactivated reserve.

In May 1999, NRG and Dynegy Power Corporation (Dynegy), through West Coast Power LLC, complet-

ed the acquisition of the Encina generating station and 17 combustion turbines for approximately $356 mil-

lion from San Diego Gas & Electric Company. The facilities, which have a combined capacity rating of

1,218 megawatts, are located near Carlsbad and San Diego, California. NRG and Dynegy each own a 50

percent interest in these facilities.

In June 1999, NRG completed its acquisition of the Huntley and Dunkirk generating stations from Niagara

Mohawk Power Corporation (NIMO) for approximately $355 million. The two coal-fired power genera-

tion facilities are located near Buffalo, New York, and have a combined capacity rating of 1,360 megawatts.

In June 1999, NRG completed its acquisition of the Arthur Kill generating station and the Astoria gas tur-

bine site from Consolidated Edison Company of New York, Inc. for approximately $505 million. These facil-

ities, which are located in the New York City area, have a combined capacity rating of 1,456 megawatts.

NRG, together with its partner and the Creditor’s committee, filed a plan with the United States Bankruptcy

court for the Middle District of Louisiana to acquire 1,708 megawatts of fossil generating assets from

Cajun Electric Power Cooperative of Baton Rouge, Louisiana (Cajun) for approximately $1.0 billion.

During the third quarter, the U.S. Bankruptcy Judge confirmed the Creditor’s Plan of Reorganization and

NRG exercised an option to purchase its partner’s 50 percent interest in the project. NRG expects to close

the acquisition of the Cajun assets in the spring of 2000.

In August, NRG agreed to sell all but a 20 percent ownership interest in Cogeneration Corporation of

America (CogenAmerica) to Calpine Corporation in connection with Calpine’s acquisition of the remaining

shares of CogenAmerica. Prior to December 1999, NRG owned approximately 45 percent of CogenAmerica.

Upon closing of the proposed transaction, all outstanding shares of CogenAmerica common stock

(other than those retained by NRG) were acquired by Calpine for a cash purchase price of $25.00 per

share. The transaction closed during the fourth quarter of 1999 and NRG retained a 20 percent ownership interest

in CogenAmerica.

In October 1999, NRG completed its acquisition of the Oswego generating station from NIMO and

Rochester Gas and Electric for approximately $85 million. The oil- and gas-fired power generating facility

which has a capacity rating of 1,700 megawatts is located on a 93-acre site in Oswego, New York. This

facility consists of two units each having a capacity rating of 850 megawatts.

On December 15, 1999, NRG acquired four fossil fuel generating stations and numerous remote gas turbines

from Connecticut Light & Power Company (CL&P) for approximately $460 million. These facili-

ties are located throughout Connecticut and have a combined capacity rating of 2,235 megawatts. NRG

entered into a Standard Offer Service Wholesale Sales Agreement with CL&P pursuant to which NRG

will supply CL&P with 35 percent of its standard offer service load during 2000, 40 percent during 2001

and 2002, and 45 percent during 2003. NRG estimates that 45 percent of CL&P’s standard offer service

load in 2003 will be approximately 2,070 megawatts at peak requirement. The Agreement terminates on

December 31, 2003.

In December 1999, NRG purchased a 50 percent interest in the Rocky Road Power Plant, a 250 megawatt

natural gas fired simple-cycle peaking facility in East Dundee, IL from Dynegy Inc., for approximately $60

million. The power plant began commercial operations on June 30, 1999 and received approval for the

installation of an additional 100 megawatt natural gas combustion turbine in October 1999, increasing

the facility’s generating capacity to a nominal 350 megawatts. The expansion is expected to be in

service before the start of the peak summer 2000 season.

N O T E F O U R Investments Accounted for by the Equity Method

NRG has investments in various international and domestic energy projects. The equity method of accounting

is applied to such investments in affiliates, which include joint ventures and partnerships, because the

ownership structure prevents NRG from exercising a controlling influence over operating and financial

policies of the projects. Under this method, equity in pretax income or losses of domestic partnerships

and, generally, in the net income or losses of international projects are reflected as equity in earnings of

unconsolidated affiliates.

Summarized financial information for investments in unconsolidated affiliates accounted for under the

equity method as of and for the year ended December 31, is as follows:

5N O T E F I V E Commitments and Contingencies

Capital Commitments—International | In November 1999, NRG agreed to purchase the 665 megawatt

Killingholme A station from National Power plc. Killingholme A was commissioned in 1994 and is a

combined-cycle, gas-turbine power station located in England. The purchase price for the station will be

approximately 410 million pounds sterling (approximately U.S. $662 million at end-of-year exchange

rates), subject to commercial adjustments. The purchase price includes 20 million pounds sterling (approxi-

mately U.S. $32 million at end-of-year exchange rates) that is contingent upon the successful completion

of negotiations regarding NRG’s purchase of National Power’s Blyth generating facilities. The Blyth assets consist

of two coal-fired stations totaling 1,140 megawatts of generation capacity located in England.

Capital Commitments—Domestic | NRG expects to complete the acquisition of 1,708 megawatts of

fossil-fueled generating assets from Cajun Electric Power Cooperative of Baton Rouge, Louisiana for

approximately $1.0 billion. The transaction is expected to close in the spring of 2000.

In January 2000, NRG agreed to purchase 1,875 megawatts of fossil-fueled electric generating capacity

and other assets from Conectiv of Wilmington, Delaware for $800 million. The fossil-fueled generating

facilities consist of Conectiv’s wholly owned BL England, Deepwater, Indian River and Vienna steam stations

plus Conectiv’s interest in the Conemaugh and Keystone steam stations. Other assets in the purchase are

the 241-acre Dorchester site located in Dorchester County, Maryland, certain Merrill Creek Reservoir

entitlements in Harmony Township, New Jersey and certain excess emission allowances.

In February 2000, NRG executed a memorandum of understanding with GE Power Systems, a division

of General Electric Company, to purchase 11 gas turbine generators and five steam turbine generators.

The purchase will take place over the next five years and is valued at approximately $500 million with an

option to purchase additional units. The 16 turbines have an equivalent generation output of 3,000

megawatts and will be installed at NRG’s existing North American plant sites.

NRG has contractually agreed to the monetization of certain tax credits generated from landfill gas sales

through the year 2007.

NRG Energy, Inc. 1999 Annual Report | Financial Review

Future capital commitments related to projects are as follows:

(Millions of Dollars)

2000 $2,700

2001 500

2002 500

2003 500

2004 500

Total $4,700

Source of Capital | NRG anticipates funding its ongoing capital commitments through the issuance of

debt, additional equity from NSP, and operating cash flows. In addition, NRG may issue a limited amount

of equity financing to third parties for funding a portion of the capital requirements.

Contractual Commitments | NRG has recently acquired various generating facilities from NIMO,

ConEd, CL&P, and others. In connection with these acquisitions NRG has entered into numerous transition

agreements that obligate NRG to maintain electric generating capability and availability at certain of these

newly acquired facilities.

In addition, NRG has entered into various transition power sales agreements related to these recent acqui-

sitions that have terms ranging from four to 10 years. These agreements generally require NRG to satisfy

specified capacity requirements and supply firm all-requirements electric service, including capacity, energy

reserves, and related services necessary to satisfy the aggregate load attributable to specified customers taking

standard offer service. NRG expects to serve these load requirements through a combination of existing

generation and power purchases.

Environmental Regulations | Environmental controls at the federal, state, regional and local levels have a

substantial impact on NRG’s operations due to the cost of installation and operation of equipment

required for compliance.

Site Contamination/Remediation | With the acquisition of the NRG Northeast assets, NRG assumed

certain liabilities for existing environmental conditions at the sites with the exception of off-site liabilities

associated with the disposal of hazardous materials and certain other environmental liabilities.

Claims and Litigation | NRG is involved in various litigation matters. NRG is actively defending these

matters and does not feel the outcome of such matters would materially impact NRG’s results of operations.
