PART I

ITEM 1 -- BUSINESS

GENERAL

NRG Energy, Inc. (NRG) is one of the leading participants in the
independent power generation industry. Established in 1989 and wholly-owned by
Northern States Power Company (NSP), NRG is principally engaged in the
acquisition, development and operation of, and ownership of interests in,
independent power production and co-generation facilities, thermal energy
production and transmission facilities and resource recovery facilities. The
power generation facilities in which NRG has interests (including those under
construction) as of December 31, 1998 have a total design capacity of 10,605
megawatts (MW), of which NRG has or will have total or shared operational
responsibility for 6,966 MW, and net ownership of, or leasehold interests in
3,300 MW. In addition, NRG has substantial interests in district heating and
cooling systems and steam generation and transmission operations. As of December
31, 1998, these thermal businesses had a steam capacity of approximately 3,750
million British thermal units (mmBtus). NRG's refuse-derived fuel (RDF) plants
processed more than 1.35 million tons of municipal solid waste into
approximately 1.1 million tons of RDF during 1998.

NRG has experienced significant growth in the last year, expanding from
2,650 MW of net ownership interests in power generation facilities (including
those under construction) as of December 31, 1997 to 3,300 MW of net ownership
interests as of December 31, 1998. This growth resulted primarily from a number
of domestic and international investments and acquisitions. NRG's total
operating revenues and equity in earnings of projects changed from $118.3
million and $26.2 million, respectively, in 1997 to $182.1 million and $81.7
million, respectively, in 1998.

NRG's headquarters and principal executive offices are located at 1221
Nicollet Mall, Suite 700, Minneapolis, Minnesota 55403. Its telephone number is
(612) 373-5300.

STRATEGY

NRG intends to continue to grow through a combination of acquisition and
greenfield development of power generation and thermal energy production and
transmission facilities and related assets in the United States and abroad. In
the United States, NRG's near-term focus will be primarily on the acquisition of
existing power generation capacity and thermal energy production and
transmission facilities, particularly in situations in which its expertise can
be applied to improve the operating and financial performance of the facilities.
In the international market, NRG will continue to pursue greenfield development
and acquisition opportunities in those countries in which it believes that the
legal, political and economic environment is conducive to increased foreign
investment. In addition to acquiring and developing power production, thermal
and RDF projects, NRG continually monitors the performance and strategic fit of
its growing portfolio of projects and, based thereon, expects that it will
decrease its ownership interest in projects from time to time, including the
complete divestiture of its interests in projects where appropriate.

RECENT EVENTS -- PROPOSED MERGER

On March 24, 1999, Northern States Power Company (NSP), NRG's parent
company, and New Century Energies, Inc., a Delaware corporation (NCE), entered
into an Agreement and Plan of Merger (the "Merger Agreement") providing for a
strategic business combination of NCE and NSP. Pursuant to the Merger Agreement,
NCE will be merged with and into NSP with NSP as the surviving corporation in
the Merger. Subject to the terms of the Merger Agreement, at the time of the
Merger, each share of NCE common stock, par value $1.00 per share ("NCE Common
Stock"), (other than certain shares to be canceled) together with any associated
purchase rights, will be converted into the right to receive 1.55 shares of NSP
common stock, par value $2.50 per share ("NSP Common Stock"). Cash will be paid
in lieu of any fractional shares of NSP Common Stock which holders of NCE Common
Stock would otherwise receive. The Merger is expected to be a tax-free
stock-for-stock exchange for shareholders of both companies and to be accounted
for as a pooling of interests.

Consummation of the Merger is subject to certain closing conditions,
including, among others, approval by the shareholders of NSP and NCE, approval
or regulatory review by certain state utilities regulators, the Securities and
Exchange Commission under the Public Utility Holding Company Act of 1935, as
amended, the Federal Energy Regulatory Commission, the Nuclear Regulatory
Commission, the Federal Communications Commission and expiration or termination
of the waiting period applicable to the Merger under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended. Each of NCE and NSP have agreed
to certain undertakings and limitations regarding the conduct of their
businesses prior to the closing of the transaction. The Merger is expected to
take from 12 to 18 months to complete.

SIGNIFICANT INVESTMENTS, ACQUISITIONS AND DIVESTITURES IN 1998

In March 1998, NRG together with its 50% partner, Dynegy, Inc. (Dynegy)
acquired the Long Beach Generating Station from Southern California Edison for
$29.8 million. The Long Beach Station is a gas-fired plant comprised of seven
gas turbine generators and two steam turbines totaling 530 MW in the aggregate.

In April 1998, NRG together with its 50% partner, Dynegy, acquired the El
Segundo Generating Station from Southern California Edison Company for $87.8
million. The El Segundo Generating Station is a gas-fired plant with a capacity
rating of 1,020 MW.

Also during April 1998, NRG exercised its option to acquire 16.8 million
convertible, non-voting preference shares of Energy Development Limited (EDL)
for AUS $37.0 million (U.S. $24.8 million), bringing NRG's total investment in
EDL to $44.5 million or approximately a 34 percent ownership interest. The
preference shares do not become convertible into EDL's common stock unless a
takeover bid is made for EDL by a person who is not an affiliate of the owner of
the preference shares and such person is, or becomes, entitled to purchase more
than 35% of EDL's outstanding common stock. In such event, if EDL fails to
comply with an obligation to appoint directors nominated by the owner of the
preference shares, the preference shares convert at the option of the owner to
common shares of EDL on a share-for-share basis. EDL is a publicly traded
company listed on the Australian Stock Exchange that owns and operates 262 MW of
generation throughout Australia and the United Kingdom. Its closing share price
as of March 23, 1999 was AUS$ 3.59.

In June 1998, NRG sold its interest in Wind Power Partners 1987 LP and Wind
Power Partners 1988 LP for $9.2 million. These companies were acquired as a part
of NRG's November 1997 acquisition of the Pacific Generation Company from
Pacificorp, Inc. There was no gain or loss recorded from the sale.

In August 1998, NRG commenced plans to sell-down its ownership in the
Enfield Energy Center project located in North London, England. Discussions with
potential partners took place in September and October 1998 culminating in the
sale in late December of one half of NRG's 50% interest in the project to an
affiliate of El Paso International for a $26.2 million gain. NRG continues to
own 25% of the Enfield project.

In October 1998, NRG sold its remaining 50% interest in Mid-Continent Power
Company, a facility in Pryor Oklahoma, to Cogeneration Corporation of America,
an affiliate of NRG, for a $2.1 million gain, after elimination of affiliate
interest. Also in October, 1998, NRG sold a 13.35% interest in ECK Generating
for a gain of $1.6 million. NRG continues to own 44.5% of the ECK Generating
project.

SIGNIFICANT EQUITY INVESTMENTS

LOY YANG POWER

NRG has a 25.4% interest in Loy Yang Power (Loy Yang) which owns and
operates a 2,000 MW brown coal fired thermal power station (the Power Station)
and the adjacent Loy Yang coal mine (the Mine) located in Victoria, Australia.
The Power Station has four generating units, each with a 500 MW boiler and turbo
generator, which commenced commercial operation between July 1984 and December
1988. In addition, Loy Yang manages the common infrastructure facilities which
are located on the Loy Yang site, which services not only the Power Station, but
also the adjacent Loy Yang B 1000 MW power station (Loy Yang B), a pulverized
dried brown coal plant, and several other nearby power stations.

2

Loy Yang is required by law to sell its entire output of electricity
(subject to certain narrow exemptions, including output used in the Power
Station and the Mine) through the competitive wholesale market for electricity
operated and administered by the Victorian Power Exchange (the Pool). There are
two components to the wholesale electricity market in Victoria. The first is the
Pool. The second is the price hedging contracts, known as Contracts for
Differences (or CFDs), that are entered into between electricity sellers and
buyers in lieu of traditional power purchase agreements, which are not available
in Victoria because of the Pool system.

Under the Victorian regulatory system, all electricity generated in
Victoria must be sold and purchased through the Pool. All licensed generators
and suppliers, including Loy Yang, are signatories to a pooling and settlement
agreement, which governs the constitution and operation of the Pool and the
calculation of payments due to and from generators and suppliers. The Pool also
provides centralized settlement of accounts and clearing. Prices for electricity
are set by the Pool daily for each half hour of the following day based on the
bids of the generators and a complex set of calculations matching supply and
demand and taking account of system stability, security and other costs. Under a
new national electricity market, the grid in Victoria has been interconnected
with that of New South Wales and limited trading is already taking place between
those states. Over the long term, there are plans for the interconnection of the
eastern seaboard states to establish what will be known as a national power
pool.

In a Pool system, it is not possible for a generator such as Loy Yang to
enter into traditional power purchase agreements. In order to provide a hedge
against Pool price volatility and to support their financings, most of the
Victorian generators have entered into CFDs with the Victorian distribution
companies, Victorian government entities and industrial users (customers). These
CFDs are financial hedging instruments, which have the effect of fixing the
price for a specified quantity of electricity for a particular seller and
purchaser over a defined period. They establish a "strike price" for a certain
volume of electricity purchased by the user during a specified period;
differences between that "strike price" and the actual price set by the Pool
give rise to "difference payments" between the parties at the end of the period.
Even if Loy Yang is producing less than its contracted quantity it will still be
required to make and will be entitled to receive difference payments for the
amounts set forth in its CFDs.

Loy Yang's current CFDs with the Victorian distribution companies and other
Victorian government entities in respect of regulated customer load (which are
called vesting contracts) cover approximately 61% of Loy Yang's forecast revenue
from generation, thus providing considerable stability in its income over that
period. Loy Yang also enters into CFDs with its unregulated or contestable
customers; these CFDs are known as hedging contracts and, together with the
vesting contracts with the regulated customers, they cover approximately 86% of
Loy Yang's forecast load at December 31, 1998. Each of the vesting contracts
expires at the end of the franchise period (December 31, 2000), by which time
all retail customers will have become contestable customers by operation of law.
Loy Yang's hedging contracts are generally for a term of one to two years, and
the volume of load covered by these contracts will increase as retail customers
progressively become contestable. Loy Yang's goal is to cover 85% of its
forecast load with hedging contracts.

Loy Yang and the State Electricity Commission of Victoria (SECV) have been
issued a joint mining license for the Mine. Under the terms of the
privatization, Loy Yang is required to mine coal to supply not only its own
Power Station but also the neighboring Loy Yang B, a nearby plant, and an
additional future power station that could be developed on a nearby site. This
requirement extends to 2027, but may be extended for an additional 30 years at
the SECV's option. Loy Yang receives a fixed capacity charge and a variable
energy charge for these services, coupled with a system of initiatives and
penalties. Loy Yang has over 70 years of economically viable coal supply at
current usage rates within its mine license area, even assuming that it is
required to continue supplying coal to the other parties beyond 2026.

On the basis of historical Australian power pool prices, absent project
debt restructuring, the Loy Yang project company will experience difficulty in
servicing its long-term debt obligations. This, in turn, could trigger a senior
debt default under the loan documents on or about June 2002.

GLADSTONE POWER STATION

The Gladstone Power Station (Gladstone) is a 1,680 MW coal-fired power
generation facility located in Gladstone, Australia. NRG acquired a 37.5%
ownership interest in Gladstone when the facility was privatized in March 1994.
The other participants in this acquisition are subsidiaries or affiliates of
Comalco Limited, Marubeni Corporation, Sumitomo Corporation and Sumitomo Light
Metal Industries, Mitsubishi Corporation and Mitsubishi Materials Corporation,
and Yoshida Kogyo (the Participants). NRG Gladstone Operating Services Pty.
Ltd., a wholly-owned subsidiary of NRG (NRG Gladstone), operates Gladstone under
an operations and maintenance agreement expiring in 2011.

Gladstone sells electricity to the Queensland Power Trading Corporation
("QPTC") and also to Boyne Smelters Limited located at Boyne Island, Queensland
(the Smelter). Pursuant to an Interconnection and Power Pooling Agreement (the
IPPA), the Participants have the right to interconnect Gladstone to the QPTC
system and QPTC is obligated to accept all electricity generated by the facility
(subject to merit order dispatch), for an initial term of 35 years. QPTC also
has agreed under the IPPA to permit the Smelter to interconnect to the QPTC
system and to provide sufficient generating capacity on its system in order to
provide an uninterrupted supply of power to the Smelter in most circumstances.
The Participants are obligated to maintain a 35% reserve margin for the Smelter
design load, but the QPTC is obligated to provide capacity support to the
Participants to make up any shortfall between the available capacity from
Gladstone and the Smelter demand at any given time.

The QPTC also entered into a 35 year Capacity Purchase Agreement (CPA) with
each of the Participants for its percentage of the capacity of Gladstone,
excluding that sold directly to the Smelter. Under the CPAs, the Participants
are paid both a capacity and an energy charge by the QPTC. The capacity charge
is designed to cover the projected fixed costs allocable to the QPTC, including
debt service and an equity return, and is adjusted to reflect variations in
interest rates. A capacity bonus is also available if the equivalent
availability factor exceeds 88% on a rolling average basis, and damages are
payable by the Participants if it is less than 82% on that same basis. As of
December 31, 1998, the two-year average equivalent availability factor was
90.1%. The QPTC also pays an energy charge, which is intended to cover fuel
costs.

The owners of the Smelter (BSL) have also entered into a Block A Power
Purchase Agreement (PPA) and Block B PPA with each Participant, providing for
the sale and purchase of such Participant's percentage share of capacity
allocated to the existing Smelter. The term of each of these PPAs is 35 years.
BSL is obligated to pay to each Participant a demand charge that is intended to
cover the fixed costs of supplying capacity to the existing Smelter and the
Smelter expansion, including debt service and return on equity. BSL also is
obligated to pay an energy charge based on the fuel cost associated with the
production of energy from the facility. The Smelter expansion resulted in an
increase in Gladstone capacity utilization from approximately 41% in 1994 to 65%
in 1998. NRG anticipates that the capacity utilization will increase to 71% in
1999 when the Smelter expansion is completed.

NRG Gladstone is responsible for operation and maintenance of Gladstone
pursuant to a 17 year operation and maintenance agreement that commenced in
1994. NRG Gladstone is entitled to a base fee of AUS$ 1.25 million per year
indexed in accordance with the Australian Consumer Price Index (ACPI)
(approximately U.S. $.850 million, based on exchange rates and ACPI in effect at
December 31, 1998), and an annual bonus based on the capacity bonuses to which
the Participants are entitled under the CPAs. NRG Gladstone is obligated to pay
liquidated damages for shortfalls in availability in an amount calculated by
reference to the liquidated damages payable by the Participants under the CPAs
and the PPAs. NRG Gladstone's obligations under the operation and maintenance
agreement are unconditionally guaranteed by NRG, subject to an aggregate
liability cap of AUS$ 25 million indexed in accordance with ACPI (approximately
U.S. $15.3 million, based on exchange rates and ACPI in effect at December 31,
1998).

COLLINSVILLE POWER STATION

The Collinsville Power Station (Collinsville) is a 189 MW coal-fired power
generation facility located in Collinsville, Australia. In March 1996, NRG
acquired a 50% ownership interest in Collinsville when it was privatized by the
Queensland State government. NRG's partner in this acquisition is Transfield
Holdings Pty
4
7

Ltd (Transfield), an Australian infrastructure contractor, with which NRG formed
an unincorporated joint venture to refurbish this plant. The joint venture
contracted with an affiliate of Transfield to complete the refurbishment of the
facility under a turn-key contract. The operation and maintenance of the
facility will be undertaken by Collinsville Operations Pty Ltd. (COPL), a 50%
owned subsidiary of NRG. COPL has entered into a maintenance contract with
Transfield to perform required maintenance on the facility and a technical
services agreement with NRG for staffing and assistance with certain operational
functions.

Collinsville Power Station commenced operations on August 11, 1998. NRG and
Transfield have entered into an 18 year Power Purchase Agreement (PPA) with
QPTC. Under this agreement QPTC will pay both a capacity and an energy charge to
the participants. The capacity charge is designed to cover the projected fixed
costs allocable to QPTC, including debt service and equity return. The energy
charge is based on the fuel costs associated with the production of energy from
the facility.

The Collinsville Power Station failed to achieve its scheduled commercial
operation date of March 1, 1998. The joint venture is liable to QPTC under the
PPA for liquidated damages of approximately AUS $27,000 per day until the
commercial operation date of August 11, 1998 up to a maximum of AUS$ 5 million
(indexed in April 1995 dollars). In late 1998 the joint venture settled the
liquidated damages with QPTC for AUS$ 4.57 million. The joint venture's remedies
under the turn-key refurbishment contract with Transfield's affiliate included a
reduction in the contract price of AUS$ 110,000 per day from March 1, 1998 to
August 11, 1998. In late 1998, NRG negotiated a settlement with Transfield,
pursuant to which Transfield agreed to pay AUS$ 12.24 million for liquidated
damages relating to the late commencement date of operations.

MIBRAG

NRG owns an indirect 33 1/3% interest in the equity of Mitteldeutsche
Braunkohlengesellschaft mbH (MIBRAG) which owns coal mining, power generation
and associated operations, all of which are located south of Leipzig, Germany.
MIBRAG is a corporation formed by the German government following the
reunification of East and West Germany, to hold two open-cast brown coal
(lignite) mining operations, a lease on an additional mine, three lignite-fired
industrial cogeneration facilities and briquette manufacturing and coal dust
plants, all located in the former East Germany. In connection with the
acquisition, NRG and its partners agreed to invest (from cash flow from MIBRAG
operations) in excess of DM 1 billion (US $599.3 million based on the exchange
rate as of December 31, 1998) by December 31, 2004 to modernize the existing
mines and power generation facilities and to develop new open-pit mines. The
German government is obligated to provide certain guarantees of bank loans to
MIBRAG relating to capital improvements to the Schleenhain mine. MIBRAG also
agreed to operate the three power generation facilities until 2005, to operate
the briquette plants in accordance with market demand until 2005, and to operate
the lignite mines until continued operation of the mines is no longer
economically justifiable. In addition, MIBRAG has made certain employee
retention commitments until 2000. Under the provisions of the sale and purchase
agreement, NRG and its partners agreed to make a deferred payment of DM 40
million to the German government in the year 2009. Under the terms of the
agreement, the obligation will be reduced by certain transportation costs
incurred by MIBRAG. As of December 31, 1998 MIBRAG had accumulated
transportation costs which fully offset the DM 40 million.

MIBRAG's cogeneration operations consist of the 110 MW Mumsdorf facility,
the 86 MW Deuben facility and the 37 MW Wahlitz facility. These facilities
provide power and thermal energy for MIBRAG's coal mining operations and its
briquette manufacturing plants. All power not consumed by MIBRAG's internal
operations is sold under an eight-year power purchase agreement with
Westsachsische Energie Aktiengesellschaft (WESAG), a recently privatized German
electric utility. NRG and PowerGen jointly, through Saale Energie Services GmbH,
provide consulting services for a fee for the operation of the MIBRAG steam and
power generation facilities, the associated electrical and thermal transmission
and distribution system and the briquette manufacturing plants, under a power
consultancy agreement with MIBRAG for the life of the facilities. After some
retrofitting was completed by MIBRAG, NRG believes that all three of these
cogeneration facilities now satisfy the current European Union environmental
regulations. MIBRAG leases these cogeneration facilities under a 13-year lease
pursuant to which MIBRAG has operating control of, and a 1% interest, in the
facilities.
5
8

MIBRAG's lignite mine operations include Profen, Zwenkau and Schleenhain
(which is under construction but has not yet commenced operations), with total
estimated reserves of 776 million metric tons. Morrison Knudsen, an
international mining company, provides consulting services to the mines under a
consultancy agreement with MIBRAG for the life of the mines. In addition to
providing approximately 3 million tons of lignite per year for MIBRAG's three
cogeneration facilities and one briquette facility, output from these mines
supplies lignite to the Schkopau power station and other facilities. The total
output of the new Schleenhain mine will be dedicated to the new 1730 MW
Lippendorf power station. MIBRAG is currently supplying coal for the existing
Lippendorf and Thierbach power generation facilities, which are expected to
close at the end of 1999. The first unit of the new Lippendorf facility is
scheduled to commence initial operation in May of 2000.

SCHKOPAU POWER STATION

In 1993, NRG and PowerGen plc of the United Kingdom each acquired a 50%
interest in a German limited liability company, Saale Energie GmbH (Saale).
Saale then acquired a 41.9% interest in a 960 MW coal-fired power plant that was
under construction in the city of Schkopau, which is located in the former East
Germany. PreussenElecktra Kraftwerke Ag (PE), a German energy company, owns the
remaining 58.1% interest in Schkopau and operates the plant. The partnership of
Saale and PE that owns the plant is called Kraftwerk Schkopau GbR (KS).

The first 425 MW unit of the Schkopau plant began operation in January
1996, the 110 MW turbine went into commercial operation in February 1996, and
the second 425 MW unit came on line in July 1996. Acceptance testing of all of
the individual pieces of equipment has been completed.

PE operates and maintains the Schkopau facility under an operation and
maintenance contract with Kraftwerk Schkopau Betriebsgesellschaft mbH, a German
limited liability company (KSB), in which Saale and PE hold interests of 44.4%
and 55.6% respectively, and which is responsible for the operation and
maintenance of the facility pursuant to certain agreements with each of Saale
and PE. PE is paid a management fee made up of several variable components that
will be adjusted according to changes in, among other things, labor costs,
producer prices for light fuel oil and prices for electricity. Pursuant to the
KSB partnership agreement between Saale and PE and the Saale shareholders
agreement between NRG and PowerGen, NRG has the right to participate in the
oversight of facility operations and in the approval and oversight of facility
budgets and policies. The plant is fueled by brown coal which will be provided
under a long-term contract by MIBRAG's Profen lignite mine.

Pursuant to the KS partnership agreement between Saale and PE, each partner
has been allocated a share of capacity and energy generated by the facility.
Saale sells its allocated 400 MW portion of the plant's capacity under a 25-year
contract with VEAG, a major German utility which controls the high-voltage
transmission of electricity in the former East Germany. VEAG pays a price that
is made up of three components, the first of which is designed to recover
installation and capital costs, the second to recover operating and other
variable costs, and the third to cover fuel supply and transportation costs. NRG
receives 50% of the net profits from these VEAG payments through its ownership
interest in Saale.

COBEE

In December 1996, NRG acquired an interest in Compania Boliviana de Energia
Electrica S.A.-Bolivian Power Company Limited (COBEE), the second largest
generator of electricity in Bolivia. The acquisition was consummated through a
Netherlands corporation, Tosli Investments B.V. (Tosli), which is equally owned
by subsidiaries of NRG and Vattenfall AB of Sweden (Vattenfall). In December
1996, Tosli completed a successful tender offer for the shares of COBEE, which
were listed on the New York Stock Exchange, acquiring 96.6% of COBEE's
outstanding common shares for a total purchase price of $175 million. COBEE
shares were delisted in January 1997. The COBEE board of directors consists of
three designees of NRG, three designees of Vattenfall and three directors
appointed jointly by NRG and Vattenfall.

COBEE has entered into an electricity supply contract with Electricidad de
La Paz S.A., a Bolivian distribution company, (Electropaz) which provides that
COBEE shall supply Electropaz with all of the
6
9

electricity that COBEE can supply, up to the maximum amount of electricity
required by Electropaz to supply the requirements of its distribution
concession. This electricity supply contract expires in December 2008. COBEE has
entered into a substantially similar contract with Empresa de Luz Fuerza
Electricade Oruro, another Bolivian distribution company, S.A. (ELF). All
payments by Electropaz and ELF are in local currency, tied to the value of the
U.S. dollar.

COBEE operates its electric generation business under a 40-year concession
granted by the Government of Bolivia in 1990, as most recently amended in March
1995. Under this concession, COBEE is entitled to earn a return of 9% after all
operating expenses, depreciation, taxes and interest expense, calculated on its
U.S. dollar rate base, consisting of net fixed assets at historical cost in U.S.
dollars and working capital and materials up to certain limits. The Bolivian
Electricity Code also provides for the adjustment of rates to compensate COBEE
for any shortfall or to recapture any excess in COBEE's actual rate of return
during the previous year. COBEE periodically applies to the Superintendent of
Electricity for rate increases sufficient to provide its 9% rate of return based
on COBEE's current operating results and its projection of future revenues and
expenses.

COGENERATION CORPORATION OF AMERICA

On January 18, 1996, the U.S. Bankruptcy Court for the District of New
Jersey awarded NRG the right to acquire a 41.86% equity interest in O'Brien
Environmental Energy, Inc. (O'Brien), which emerged from bankruptcy on April 30,
1996 and was renamed "NRG Generating (U.S.) Inc." (NRGG). On July 20, 1998,
NRGG's name was changed to Cogeneration Corporation of America (CogenAmerica).
NRG currently holds 45.21% of the common stock of CogenAmerica. The remaining
54.79% of the common stock is held publicly. CogenAmerica has interests in six
domestic operating projects with an aggregate capacity of approximately 575 MW.
CogenAmerica's principal operating projects include: (a) the 54 MW Newark
Boxboard Project (which is owned 100% by a wholly-owned project subsidiary of
CogenAmerica), a gas-fired cogeneration facility that sells electricity to
Jersey Central Power & Light (JCP&L) and steam to Newark Group Industries, Inc.;
(b) the 122 MW E.I. du Pont Parlin Project (which is owned 100% by a
wholly-owned project subsidiary of CogenAmerica), a gas-fired cogeneration
facility that sells electricity to JCP&L and steam to E.I. du Pont de Nemours
and Company; (c) an 83% interest in a 22 MW standby/peak sharing facility which
provides electricity and standby capabilities for the Philadelphia Municipal
Authority; (d) a 33.33% interest in the 150 MW Grays Ferry project, a gas-fired
cogeneration project located in Philadelphia, Pennsylvania, which sells
electricity to Philadelphia Electricity Company (PECO). PECO recently attempted
to terminate the PPA with respect to the Grays Ferry project. The Grays Ferry
partnership in turn commenced litigation claiming there is no basis for
termination of such agreement. (See "Item 3 -- Legal Proceedings."); (e) the 117
MW Morris project, a gas-fired cogeneration project located in Morris, Illinois,
which sells electricity and steam to Equistar Chemicals; (f) the 110 MW MCPC
project, a gas-fired cogeneration project located in Pryor, Oklahoma, which
sells electricity to Oklahoma Gas and Electric and steam to a number of
industrial users.

On October 9, 1998, CogenAmerica acquired NRG's 50% interest in MCPC, a 110
MW cogeneration project located in Pryor, Oklahoma. CogenAmerica also acquired
the remaining 50% interest in this project from Decker Energy International.
Inc., and associated entities. The project sells electricity to Oklahoma Gas and
Electric and steam to a number of industrial users. The purchase price was
approximately $23.9 million. NRG loaned CogenAmerica approximately $23.9 million
to finance the acquisition. The loan is a six-year term facility requiring
interest and variable principal and interest payments on a quarterly basis,
based on project cash flows.

On December 30, 1997 CogenAmerica acquired from NRG 100% of the membership
interests in NRG (Morris) Cogen, LLC which was building a 117 MW cogeneration
plant on the site of the Equistar Chemicals, LP (Equistar) manufacturing
facility in Morris, Illinois. In connection with the sale, NRG committed to
finance the acquisition price pursuant to a loan agreement between NRG and
CogenAmerica and NRG guaranteed the obligation of CogenAmerica to invest equity
into the project company. At December 31, 1998, CogenAmerica had borrowed $12
million from NRG to partially fund its equity investment for the project.

CogenAmerica's Morris facility experienced two unscheduled outages in
January 1999, which resulted in service and business interruptions to Equistar.
NRG, as a provider of construction management services and operation and
maintenance services to the Morris facility has participated with CogenAmerica
and Equistar in an investigation into this matter. This investigation, which
includes an examination of the respective rights and obligations of the parties
with respect to one another and with respect to potentially responsible third
parties, including insurers, is continuing. Although it is not possible at the
present time to assess NRG's potential exposure related to the two outages, NRG
does not believe that any claims which may be brought against it will have a
material financial impact on NRG.

NRG employees serve as NRG's designees on the board of directors of
CogenAmerica. NRG and CogenAmerica also entered into a "Co-Investment
Agreement", pursuant to which NRG granted CogenAmerica a right of first offer
until April 30, 2003 to acquire from NRG each energy development project first
developed or acquired by NRG for which a co-investor is required because of
federal or state regulatory restrictions on NRG's ownership. In addition, NRG
has agreed that, prior to May 1, 1999, a minimum of one or more such projects,
having an aggregate equity value of at least $60 million or a minimum power
generation capacity of 150 MW, will be so offered. NRG has fulfilled the minimum
requirements of the Co-Investment Agreement. To facilitate CogenAmerica's
ability to acquire projects under the Co-Investment Agreement, NRG is obligated
to provide financing on Co-Investment projects to CogenAmerica to the extent
that they are unable to obtain funds on comparable terms from other sources.

NRG has also agreed to certain provisions designed to protect the rights of
the holders of the equity in CogenAmerica that is not owned by NRG. These
provisions include super-majority voting requirements with respect to a merger
or sale of all or substantially all of CogenAmerica's assets and certain
additional issuances of CogenAmerica stock, the creation of an independent
committee of the board of directors of CogenAmerica with authority to, among
other things, determine whether CogenAmerica will exercise its right of first
offer under the Co-Investment Agreement and a commitment that, for a seven-year
period following NRG's investment in CogenAmerica, NRG will not remove or vote
down the re-election to CogenAmerica's board of directors of any of the three
directors who constitute the independent directors committee.

During the third quarter of 1998, NRG solicited proxies and written
consents in favor of the removal of Mr. Robert Sherman as a member of the Board
of Directors of CogenAmerica. On October 26, 1998, NRG delivered consents for
the holders of more than 50% of CogenAmerica's shares in favor of removing Mr.
Sherman from the CogenAmerica Board. At a CogenAmerica Board meeting held on
October 27, 1998, Michael O'Sullivan, an employee of NRG, was appointed to fill
the vacancy created by the removal of Mr. Sherman. At the same meeting, Julie A.
Jorgensen, also an employee of NRG, was elected as Interim President and CEO of
CogenAmerica, replacing Mr. Sherman. At a Special Meeting of the CogenAmerica
stockholders held on November 12, 1998, the stockholders approved the removal of
Mr. Sherman as a director of CogenAmerica, with 77.3% of the outstanding shares
voting in favor of such removal. On the same day, the CogenAmerica Board
confirmed the appointment of Mr. O'Sullivan to fill the vacancy created by the
removal of Mr. Sherman. A search for a permanent President and CEO for
CogenAmerica is ongoing.

CogenAmerica and NRG have entered into various loan agreements. At December
31, 1998, the loan balance due to NRG was $40.4 million with a maturity dates
from 2001 to 2005.

CogenAmerica's shares are traded on The NASDAQ National Market under the
symbol "CGCA". CogenAmerica's closing share price as of March 23, 1999 was
$8.25.

SIGNIFICANT WHOLLY-OWNED OPERATIONS

MINNEAPOLIS ENERGY CENTER (MEC)

MEC provides steam and chilled water to customers in downtown Minneapolis,
Minnesota. MEC currently provides 91 customers with 1.6 billion pounds of steam
per year and 37 customers with 43.5 million ton hours of chilled water per year.
NRG acquired MEC in August 1993 for approximately $110 million. MEC's assets
include two combined steam and chilled water plants, three chilled water plants,
two steam

8
11

plants, six miles of steam and two miles of chilled water distribution lines.
The MEC plants have a combined steam capacity of 1,323 mmBtus per hour (388 MWt)
and cooling capacity of 35,550 tons per hour.

MEC provides steam and chilled water to its customers pursuant to energy
supply agreements, which expire at varying dates from December 1998 to March
2018. Historically, MEC has renewed its energy supply agreements as they near
expiration. With minor exceptions, these agreements are standard form contracts
providing for a uniform rate structure consisting of three components: a demand
charge designed to recover MEC's fixed capital costs, a consumption charge
designed to provide a per unit margin, and an operating charge designed to pass
through to customers all fuel, labor, maintenance, electricity and other
operating costs. The demand and consumption charges are adjusted in accordance
with the Consumer Price Index every five years.

ROCK-TENN

The Rock-Tenn process steam operation, which is owned and operated by NRG,
consists of a five-mile closed-loop steam/condensate line that delivers steam to
the Rock-Tenn Company (RTC) (formerly Waldorf Corporation), a paper manufacturer
in St. Paul, Minnesota, and has a peak steam capacity of 430 mmBtus per hour
(126 MWt). As a result of the settlement of a 1987 dispute between RTC and
NORENCO Corporation (a predecessor of NRG), RTC prepaid revenues for future
steam service. As of December 31, 1998, deferred revenues remaining were $3.4
million.

NRG delivers steam to RTC under a steam sales agreement, pursuant to which
RTC is obligated to purchase its total energy needs for its St. Paul, Minnesota
facility through June 30, 2007. The agreement does not obligate RTC to purchase
a minimum quantity of energy. Instead, RTC failure to acquire a certain quantity
of energy during a given contract year triggers an NRG right to terminate the
agreement, unless RTC elects to compensate NRG for the deficit energy usage
amount.

NEO CORPORATION (NEO)

NEO is a wholly-owned project subsidiary of NRG that was formed to develop
small power generation facilities, ranging in size from 1 to 50 MW, in the
United States. NEO is currently focusing on the development and acquisition of
landfill gas projects and the acquisition of small hydroelectric projects.

Through the investment vehicle Northbrook Energy, L.L.C. (Northbrook), NEO
has a 50% interest in eighteen small operating hydroelectric projects, ranging
in size from 1 MW to 6 MW and having a total capacity of 39.3 MW. As of December
31, 1998, NEO's total investment in these projects was $3.6 million.

NEO has a 50% interest in 21 operating landfill gas projects, as of
December 31, 1998, ranging in size from 1 MW to 11 MW. As of December 31, 1998,
NEO's equity investment in these projects totaled $7.7 million and loans to fund
development, construction and start-up amounted to $23.7 million. In addition,
NEO has 11 landfill gas projects under construction. NEO expects its total
funding requirements to be approximately $136 million and total capacity of the
portfolio is expected to reach 100 MW in 1999.

On September 24, 1997, certain affiliates of NEO entered into a
Construction, Acquisition and Term Loan Agreement with Lyon Credit Corporation
(Lyon) for $92 million to fund the construction of the landfill gas collection
systems and generation facilities for certain NEO landfill gas projects in
development. The construction loan for each project will convert to a term loan
containing a maximum maturity date of ten years. NRG has agreed to provide Lyon
with a guarantee during the construction loan period. In addition, NRG has
agreed to guarantee the monetization and use of the Section 29 tax credits
generated from the landfill gas projects financed by Lyon through the year 2007.

An important factor in the after tax return of the landfill gas projects is
the eligibility of these projects for Section 29 tax credits. The Section 29 tax
credit is available only to projects that produce "qualified fuels". Landfill
gas is a qualified fuel for purposes of the Section 29 credit. To qualify for
the credit, the facility for producing gas must have been placed in service no
later than June 30, 1998. Congress has not renewed the Section 29 credit for new
landfill gas projects.

RESOURCE RECOVERY FACILITIES

NRG's Newport resource recovery facility, located in Newport, Minnesota,
can process over 1,500 tons of Municipal Solid Water, (MSW) per day, 92% of
which is recovered as refuse derived fuel (RDF) or other recyclables and reused
in power generation facilities in Red Wing and Mankato, Minnesota. The Newport
facility, which was originally constructed and operated by NSP, was transferred
to NRG in 1993. NRG owns 100% of and operates and maintains the Newport
facility.

Pursuant to service agreements with Ramsey and Washington Counties,
(Counties), which expire in 2007, NRG processes a minimum of 280,800 tons of MSW
per year at the Newport facility and receives service fees based on the amount
of waste processed, pass-through costs and certain other factors. NRG is also
entitled to an operation and maintenance fee, which is designed to recover fixed
costs and to provide NRG a guaranteed amount for operating and maintaining the
Newport facility for the processing of 750 tons per day of MSW, whether or not
the Counties deliver such waste for processing.

Since 1989, NRG has operated the Elk River resource recovery facility
located in Elk River, Minnesota, which can process over 1,500 tons of MSW per
day, 90% of which is recovered as RDF or other recyclables and reused in power
generation facilities in Elk River and Mankato, Minnesota. NSP owns 85% of the
Elk River facility, and United Power Association owns the remaining 15%.

NRG also provides ash storage and disposal for the Elk River facility at
NSP's Becker ash disposal facility, an approved ash deposit site adjacent to
NSP's Sherburne County generating facility near Becker, Minnesota. NRG operates
the Becker facility on behalf of NSP. Pursuant to an ash management services
agreement between NSP and the NSP Service Counties, NSP receives an ash disposal
fee based on the amount of ash disposal, pass-through costs and certain other
factors.

RDF projects, such as NRG's Newport facility and NSP's Elk River facility,
historically were assured adequate supply of waste through state and local flow
control legislation, which directed that waste be disposed of in certain
facilities. In May 1994, the United States Supreme Court held that such waste
was a commodity in interstate commerce and, accordingly, that flow control
legislation that prohibited shipment of waste out of state was unconstitutional.
Since this ruling, the RDF facilities have faced increased competition from
landfills in surrounding states in obtaining MSW; however, this has not impacted
NRG's MSW volumes to date.

SIGNIFICANT PENDING ACQUISITIONS, DISPOSITIONS AND PROJECTS UNDER DEVELOPMENT

In October 1998, the Company executed a binding agreement to purchase the
Somerset power station for approximately $55 million from Eastern Utilities
Association (EUA). The Somerset station located in Somerset, Massachusetts,
includes two coal-fired generating facilities supplying a total of 181 megawatts
and two aeroderivative combustion turbine peaking units supplying a total of 48
megawatts. In addition, a total of 69 megawatts is on deactivated reserve. The
Company will hold a 100% interest in the project and will own, operate and
maintain the units. Consummation of the transaction is expected to occur on or
before March 31, 1999, but is contingent on receipt of regulatory approvals and
consents from a number of governmental and private parties. There can be no
assurances that these approvals and consents will be received.

In December 1998, NRG and Dynegy signed agreements with San Diego Gas &
Electric Company to jointly acquire 1,218 megawatts of power generation
facilities located near Carlsbad and San Diego California for $356 million. NRG
and Dynegy will each own 50% interest in these facilities. This transaction is
expected to close in second quarter of 1999 pending regulatory approval.

In December 1998, NRG signed agreements with Niagara Mohawk Power to
purchase two coal fired power generation facilities located near Buffalo with a
combined summer capacity rating of 1,360 MW for $355 million. This transaction
is expected to close in the second quarter of 1999 pending regulatory approval.

In January 1999, NRG executed a binding agreement with Consolidated Edison
Company of New York (ConEdison) to acquire the Astoria gas turbines facility and
the Arthur Kill Generating Station for $505 million. These facilities, which are
located in New York, have a combined summer capacity rating of 1,456 MW. This
transaction is expected to close in the second quarter of 1999 pending
regulatory approval.

10
13

In February 1999, NRG purchased from Thermal Ventures, Inc. (TVI) the
remaining 50.1% limited partnership interests held by TVI in San Francisco
Thermal Limited Partnership and Pittsburgh Thermal Limited Partnership for $12.3
million. In addition, upon receipt of California and Pennsylvania regulatory
approval, NRG will acquire TVI's 50% member interest in North America Thermal
Systems, LLC (the entity holding the general partnership interest in the San
Francisco and Pittsburgh partnerships) for $500,000.

ENFIELD

In December 1996, NRG reached an agreement with Indeck Energy Services
(Europe) (Indeck) to sell a 50% interest in the Enfield Energy Center, a 350 MW
gas-fired project in the North London borough of Enfield. The power station is
scheduled to begin commercial operations in late 1999. In December 1998, NRG
sold one-half of its 50% interest in the Enfield project to an affiliate of El
Paso International.

ESTONIA

In December 1996, representatives of the Estonian Government, the
state-owned Eesti Energia ("EE"), and NRG signed a development and cooperation
agreement (DCA). The DCA defines the terms under which the parties are to
establish a plan to develop and refurbish the Balti and Eesti Power Plants.
Pursuant to the DCA, a business plan for the joint project was submitted in June
1997. In September 1997, the Estonian Government rejected NRG's business plan.
However, early in 1998 the Estonian Government and EE agreed to work on a new
business plan with NRG, which was submitted in May 1998. NRG has stated its
willingness to invest up to $67.25 million of equity into the project and to
assist the joint project in obtaining non-recourse debt to fund the required
capital improvements to the Balti and Eesti Power Plants. A commission has been
established to negotiate all terms and agreements between NRG, EE and the
Estonian Government relating to the purchase of the Balti and Eesti Power
Plants. The negotiation process is expected to be complete by late 1999.

NRG has a policy of expensing all costs until there is a signed contract
and Board of Directors approval. All such costs with respect to Estonia have
been expensed.

CAJUN

NRG, together with two other parties and the Chapter 11 Trustee, have filed
a reorganization plan with the United States Bankruptcy Court for the Middle
District of Louisiana to acquire the fossil generating assets of Cajun Electric
Power Cooperative of Baton Rouge, Louisiana (Cajun) for approximately $1.2
billion. The NRG consortium has the support of the Chapter 11 trustee and
Cajun's secured creditors. On February 11, 1999, the Court issued an order
denying confirmation of NRG's plan and the reorganization plan proposed by a
competing bidder. NRG along with its partners and the Trustee are contemplating
submitting a revised plan on April 16, 1999 to accommodate the issues raised in
the Court's February 11, 1999 decision. The court has scheduled hearings and
activities to review the new plans in May and June of 1999.

SUNNYSIDE

In 1994, NRG, through a wholly-owned subsidiary, purchased a 50% ownership
interest in Sunnyside Cogeneration Associates, a Utah joint venture, which owns
and operates a 58 MW waste coal plant in Utah. The waste coal plant is currently
being operated by a partnership that is 50% owned by an NRG affiliate. NRG and
its partner's effort to restructure the debt of the Sunnyside project have not
been successful. Due to the lack of progress in restructuring the debt, NRG
wrote down its investment in the Sunnyside project by $8.9 million in 1997 and
wrote off the $1.9 million balance of its investment in 1998. 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. The
sale is expected to close during the second quarter of 1999.

Because of the many complexities inherent in the acquisition, development
and financing of projects, there can be no assurance that any of NRG's pending
acquisitions and projects under development, including those described above,
will be consummated.

PROJECT AGREEMENTS

In the past, virtually all of NRG's operating power generation facilities
have sold electricity under long-term power purchase agreements. A facility's
revenue from a power purchase agreement usually consists of two components:
energy payments and capacity payments. Energy payments, which are intended to
cover the variable costs of electric generation (such as fuel costs and variable
operation and maintenance expense), are normally based on a facility's net
electrical output measured in kilowatt hours, with payment rates either fixed or
indexed to the fuel costs of the power purchaser. Capacity payments, which are
generally intended to provide funds for the fixed costs incurred by the project
subsidiary or project affiliate (such as debt service on the project financing
and the equity return), are normally calculated based on the net electrical
output or the declared capacity of a facility and its availability.

A number of the more recent projects in which NRG has acquired or is
acquiring an interest do not have long-term power purchase agreements. For
example, Loy Yang does not have such agreements because under the new Australian
regulatory process, all generators must sell their output to a grid, where the
price is established by a neutral regulator based on the market prices during
each defined period. The same will be true of Enfield, since the United Kingdom
has adopted a similar regulatory process. Similarly, the El Segundo and Long
Beach projects are merchant plants, selling power through a newly established
independent system operator. In the case of the Kladno project, where there is a
long-term agreement, the energy price is tied to the market price of electricity
rather than to the costs incurred by the project, so the contract does not
provide the traditional level of certainty and protection. While these
"merchant" projects introduce new risks and uncertainties, and require careful
advance analysis of the local power markets, NRG believes that merchant projects
are becoming increasingly accepted in the independent power market.

REGULATION

NRG is subject to a broad range of federal, state and local energy and
environmental laws and regulations applicable to the development, ownership and
operation of its United States and international projects. These laws and
regulations generally require that a wide variety of permits and other approvals
be obtained before construction or operation of a power plant commences and
that, after completion, the facility operate in compliance with their
requirements. NRG strives to comply with the terms of all such laws,
regulations, permits and licenses and believes that all of its operating plants
are in material compliance with all such applicable requirements. No assurance
can be given, however, that in the future all necessary permits and approvals
will be obtained and all applicable statutes and regulations complied with. In
addition, regulatory compliance for the construction of new facilities is a
costly and time-consuming process, and intricate and rapidly changing
environmental regulations may require major expenditures for permitting and
create the risk of expensive delays or material impairment of project value if
projects cannot function as planned due to changing regulatory requirements or
local opposition. Furthermore, there can be no assurance that existing
regulations will not be revised or that new regulations will not be adopted or
become applicable to NRG which would have an adverse impact on its operations.

EMPLOYEES

At December 31, 1998, NRG had 439 employees, approximately 341 of whom are
employed directly by NRG and approximately 98 of whom are employed by its
wholly-owned subsidiaries.

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

Management's Discussion and Analysis of Financial Condition and Results of
Operations is omitted per conditions as set forth in General Instructions I (1)
(a) and (b) of Form 10-K for wholly owned subsidiaries. It is replaced with
management's narrative analysis of the results of operations set forth in
General Instructions I (2) (a) of Form 10-K for wholly-owned subsidiaries
(reduced disclosure format). This analysis will primarily compare NRG's revenue
and expense items for the year ended December 31, 1998 with the year ended
December 31, 1997.

RESULTS OF OPERATIONS

FOR THE YEAR ENDED DECEMBER 31, 1998 COMPARED TO THE YEAR ENDED DECEMBER 31,
1997

Net income for the year ended December 31, 1998, was $41.7 million, an
increase of $19.7 million or 90%, compared to net income of $22.0 million in the
same period in 1997. This increase was due to the factors described below.

REVENUES

For the year ended December 31, 1998, NRG had total revenues of $182.1
million, compared to $118.3 million for the year ended December 31, 1997, an
increase of $63.8 million or 54%. NRG's operating revenues from wholly owned
operations for the twelve months ended December 31, 1998 were $100.4 million, an
increase of $8.4 million, or 9.1%, over the same period in 1997. The increase in
revenues was due primarily to new projects, including certain Pacific Generation
operations. This increase was partially offset by lower revenues from certain
heating and cooling subsidiaries due to the unusually mild weather. For the
twelve months ended December 31, 1998, revenues from wholly owned operations
consisted primarily of revenue from heating, cooling and thermal activities
(46.0%), electrical generation (46.2%) and technical services (7.8%).

Equity in earnings of unconsolidated affiliates was $81.7 million for the
year ended December 31, 1998, compared to $26.2 million for the year ended
December 31, 1997, an increase of $55.5 million or 212%. The increase was due to
new projects including El Segundo, Long Beach and certain Pacific Generation
operations, an increase in the Company's holdings in EDL as well as improved
performance from Loy Yang. Since the increase in revenues is primarily the
result of new projects, the rate of revenue increase may not be sustained unless
new projects are acquired at the same rate.

OPERATING COSTS AND EXPENSES

Cost of wholly owned operations was $52.4 million for the year ended
December 31, 1998. This is an increase of $5.7 million or 12% over the same
period in 1997. The increase was due primarily to new projects. Cost of
operations, as a percentage of revenues from wholly owned operations for the
year, was 52% which is 1% higher than the same period in 1997. The increase in
cost of operations was due to new NEO projects and Thermal fixed expenses that
could not be recovered due to the mild weather conditions.

Depreciation and amortization costs were $16.3 million for the year ended
December 31, 1998, compared to $10.3 million for the year ended December 31,
1997. The depreciation and amortization increase was due primarily to increased
amortization of intangible assets related to the Pacific Generation acquisition
and additional NEO project depreciation.

General, administrative and development costs were $56.4 million for the
year ended December 31, 1998, compared to $43.1 million for the year ended
December 31, 1997. The increase was due primarily to increased business
development activities and increased legal, technical, and accounting expenses
resulting from expanded operations. As a percent of total revenues,
administrative and general expenses declined to 31% from 36% during the same
period one-year earlier.

18
21

OTHER INCOME (EXPENSE)

Minority interest in projects was $2.3 million for the twelve month period
compared to $.1 million for the same period in 1997. Minority interest relates
to certain Pacific Generation projects that were acquired in November 1997.

NRG recorded a total gain of $29.9 million in 1998 related to project
sales. In October, NRG sold its 50% owned 110 MW Mid-Continent Power Company
facility in Oklahoma to Cogeneration Corporation of America (CogenAmerica), an
affiliate of NRG for a $2.1 million gain. Also in October, NRG sold 13.35% of
its interest in ECK Generating for a gain of $1.6 million. NRG continues to own
44.5% of the ECK Generating project. In December, NRG sold one-half of its 50%
interest in its Enfield project to an affiliate of El Paso International for a
$26.2 million gain. Additionally, NRG sold Wind Power Partners 1987 LP and Wind
Power Partners 1988 LP for $9.2 million. There was no gain or loss recorded from
the sale of the Wind Power projects which were acquired as part of the Pacific
Generation acquisition.

NRG recorded $26.7 million in total project write-downs during the year. In
September, NRG recorded a $20.1 million charge to write-down its West Java,
Indonesia project due to uncertainties surrounding all infrastructure projects
in Indonesia. NRG recorded an additional $1.9 million charge in December to
bring its remaining investment in the project to zero. In addition, NRG wrote
off its $1.9 million investment in the Sunnyside project (U.S.) and $2.8 million
of accumulated project development expenditures related to the Alto Cachopoal
project (Chile).

Other income was $8.4 million for the twelve months ended December 31, 1998
compared with $11.8 million for the twelve months ended December 31, 1997. The
$3.4 million decline was due primarily to a reduction in interest income from
loans to affiliates.

Interest expense was $50.3 million for the twelve months ended December 31,
1998 compared with $31.0 million for the twelve months ended December 31, 1997.
The increase in interest expense was due primarily to the issuance of the $250
million Senior Notes at the end of June 1997, interest on NRG's revolving line
of credit, new debt obtained for certain NEO projects and the purchase of
Pacific Generation.

INCOME TAX

NRG has recognized an income tax benefit due to the recognition of certain
tax credits. The net income tax benefit for the year ended December 31, 1998,
increased by $2.2 million to $25.7 million as compared to $23.5 million in the
same period one year earlier. The increase in tax benefits for the twelve months
period was due to increased interest expense on corporate debt and an $8.3
million increase in Section 29 credits, which was partially offset by higher
earnings.

YEAR 2000

To the extent allowed, the information in the following section is
designated as a "Year 2000 Readiness Disclosure." NRG is incurring costs to
modify or replace existing technology, including computer software, for
uninterrupted operation in the year 2000 and beyond. A committee made up of
senior management is leading NRG's initiatives to identify Y2K related issues
and remediate business processes as necessary. NRG is also partnering with its
parent, NSP, to ensure a consistent overall company process in addressing the
Y2K issue.

NRG Y2K programs cover not only NRG's internal computer applications, but
also the thousands of hardware and embedded system components in use at NRG's
projects throughout the world. Embedded systems perform mission-critical
functions in all parts of operations, including power generation, transmission,
distribution, communications and business operations. NRG has implemented a
methodology consistent with NSP that includes state-of-the-art best practices
and standards within the energy industry. This seven-step process includes:

- Discovery of possible date-related logic in components, systems and
processes

- Assessment of potential problems

- Development of a plan to address the problem
19
22

- Attempt to resolve the problem

- Testing to verify that the solutions are workable

- Implementation of the solution to production

- Closure through re-testing and documentation and review by the Y2K senior
committee.

NRG's timetable for Y2K completion is:

- Assessment/discovery -- November 1, 1998

- Analysis/testing -- May 1, 1999

- Y2K Ready -- July 1, 1999

NRG is communicating with its key suppliers and business partners regarding
their Y2K progress, particularly in software and embedded components areas, to
determine the areas in which NRG's operations may be vulnerable to those
parties' failure to complete their redemption efforts. NRG is currently
evaluating and initiating follow-up actions regarding the responses from these
parties as appropriate.

NRG has made significant progress implementing its Y2K plan. Based upon the
information currently known regarding its internal operations and assuming
successful and timely completion of its redemption plan, NRG does not anticipate
significant business disruptions from its internal systems due to the Y2K issue.
However, NRG may possibly experience limited interruptions to some aspects of
its activities, relating to information technology, operations and
administrative functions. NRG is considering such potential occurrences in
planning for its most reasonably likely worst case scenarios.

In addition, risk exists regarding the noncompliance of third parties with
key business or operational importance to NRG. Y2K problems affecting key
customers, interconnected utilities, fuel suppliers and transporters,
telecommunication providers or financial institutions could result in lost power
or gas sales, reduction in power production or transmission, or internal
functional and administrative difficulties on the part of NRG. NRG is not
presently aware of any such situations; however occurrences of this type, if
severe, could have a material adverse impact upon the business, operating
results or financial condition of NRG. Consequently, there can be no assurance
that NRG will be able to identify and correct all aspects of the Y2K problem
that affect it in sufficient time, or that the costs of achieving Y2K readiness
will not be material.

NRG is currently updating contingency plans for all material Y2K risk and
is on track to meet the contingency planning schedule set forth by NSP. Among
the areas contingency planning will address are delays in completion of NRG's
remediation plans, failure or incomplete remediation results and failure of key
third party contracts to be Y2K compliant.

Through 1998, NRG had spent approximately $5.8 million for Y2K efforts,
including NRG's share of costs incurred by unconsolidated affiliates. These
costs were primarily expensed as incurred. The additional development and
remediation costs necessary for NRG and its affiliates to prepare for Y2K is
estimated to be approximately $3.2 million.

FORWARD-LOOKING STATEMENTS

In addition to any assumptions and other factors referred to specifically
in connection with the forward-looking statements contained in this Form 10-K,
factors that could cause NRG's actual results to differ materially from those
contemplated in any forward-looking statements include, among others, the

transportation problems or other developments; environmental incidents;
or electric transmission or gas pipeline system constraints;

- Employee workforce factors including loss or retirement of key
executives, collective bargaining agreements with union employees, or
work stoppages;

- Increased competition in the power generation industry;

- Cost and other effects of legal and administrative proceedings,
settlements, investigations and claims;

- Technological developments that result in competitive disadvantages and
create the potential for impairment of existing assets;

- Factors associated with various investments including conditions of final
legal closing, foreign government actions, foreign economic and currency
risks, political instability in foreign countries, partnership actions,
competition, operating risks, dependence on certain suppliers and
customers, domestic and foreign environmental and energy regulations;

- Limitations on NRG's ability to control the development or operation of
projects in which NRG has less than 100% interest;

- Other business or investment considerations that may be disclosed from
time to time in NRG's Securities and Exchange Commission filings or in
other publicly disseminated written documents, including NRG's
Registration Statement No. 333-33397, as amended.

NRG undertakes no obligation or publicly update or revise any
forward-looking statements, whether as a result of new information, future
events or otherwise. The foregoing review of factors pursuant to the Act should
not be construed as exhaustive.

NOTE 1 -- 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 corporations which
were merged into the Company subsequent to its incorporation. The Company and
its subsidiaries and affiliates develop, build, acquire, own and operate
non-regulated energy-related businesses.

NOTE 2 -- 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). All significant
intercompany transactions and balances have been eliminated in consolidation. As
discussed in Note 5, NRG has investments in partnerships, joint ventures and
projects for which the equity method of accounting is applied. Earnings from
equity in international investments are recorded net of foreign income taxes.

CASH EQUIVALENTS

Cash equivalents include highly liquid investments (primarily commercial
paper) with a remaining maturity of three months or less at the time of
purchase.

RESTRICTED CASH

Restricted cash consists primarily of cash collateral for letters of credit
issued in relation to project development activities and funds held in trust
accounts to satisfy the requirements of certain debt agreements.

INVENTORY

Inventory is valued at the lower of average cost or market and consists
principally of spare parts and raw materials used to generate steam.

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:

<TABLE>
<S> <C>
Facilities and improvements................................. 10-45 years
Machinery and equipment..................................... 7-30 years
Office furnishings and equipment............................ 3-5 years
</TABLE>

CAPITALIZED INTEREST

Interest incurred on funds borrowed to finance projects expected to require
more than three months to complete is capitalized. Capitalization of interest is
discontinued when the project is completed and considered operational.
Capitalized interest is amortized using the straight line method over the useful
life of the related project. Capitalized interest was $172,000 and $98,000 in
1998 and 1997, respectively.

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

28
31

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.

DEBT ISSUANCE COSTS

Costs to issue long-term debt have been capitalized and are being amortized
over the terms of the related debt.

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 seven to twenty-eight 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 as discussed in Note 9. Current federal and state
income taxes are payable to or receivable from NSP. NRG records income taxes
using the liability 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.
Investment tax credits are deferred and amortized over the estimated lives of
the related property. NRG's policy for income taxes related to international
operations is discussed in Note 9.

REVENUE RECOGNITION

Under fixed-price contracts, revenues are recognized as deliveries of
products or services are made. 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 foreign
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.

USE OF ESTIMATES

In recording transactions and balances resulting from business operations,
NRG uses estimates based on the best information available. Estimates are used
for such items as plant depreciable lives, tax provisions, uncollectible
accounts and actuarially determined benefit costs. 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 reclassifications have been made to the 1997 financial statements
to conform to the 1998 presentation. These reclassifications had no effect on
net income or stockholder's equity as previously reported.

NOTE 3 -- BUSINESS ACQUISITIONS AND DIVESTITURES

In March 1998, the Company along with its 50% partner, Dynegy, Inc.
(Dynegy) acquired the Long Beach Generating Station from Southern California
Edison for $29.8 million. The Long Beach Station is a gas-fired plant comprised
of seven gas turbine generators and two steam turbines totaling 530 megawatts
(MW) in the aggregate.

In April 1998, the Company along with its 50% partner, Dynegy, acquired the
El Segundo Generating Station from Southern California Edison Company for $87.8
million. The El Segundo Generating Station is a gas-fired plant with a capacity
rating of 1,020 MW.

In April 1998, the Company exercised its option to acquire 16.8 million
convertible, non-voting preference shares of Energy Development Limited (EDL)
for $24.8 million, bringing the Company's total investment in EDL to $44.5
million or approximately a 34 percent ownership interest. EDL is a listed
Australian company that owns and operates 262 MW of generation throughout
Australia and the United Kingdom.

In June 1998, the Company sold its interest in Wind Power Partners 1987 LP
and Wind Power Partners 1988 LP for $9.2 million. These companies were acquired
as part of the Pacific Generation acquisition. There was no gain or loss
recorded from the sale.

In 1996, the Company formed a joint venture with Ansaldo Energia SpA, a
major Italian industrial company ("Ansaldo"), and P.T. Kiani Metra, an
Indonesian industrial company ("PTKM") to develop a 400-megawatt coal-fired
power generation facility in West Java, Indonesia, through P.T. Dayslistrik
Pratama ("PTDP"), a limited liability company created by the joint venturers.
The Company and Ansaldo each have an ownership interest of 45 percent in PTDP,
with the remaining 10% held in PTKM. During 1998, the Company recorded a $22.0
million write-down of its investment in the West Java project due to the
continuing political and economic instability in Indonesia.

In September 1998, the Company announced plans to start direct negotiations
with the government of Estonia to form a joint venture with Eesti Energia for
ownership of two of Estonia's largest power plants (Narva Power). Eesti Energia
is Estonia's national electricity generator and distributor.

In October 1998, the Company executed a binding agreement to purchase the
Somerset power station for approximately $55 million from Eastern Utilities
Association (EUA). The Somerset station, located in Somerset, Massachusetts,
includes two coal-fired generating facilities and two aeroderivative combustion
turbine peaking units supplying 229 MW in aggregate, of which 69 MW is on
deactivated reserve. The project's financial close is expected to occur in the
first quarter of 1999, pending regulatory approval.

In October 1998, the Company sold its interest in the Mid-Continent Power
Company (MCPC) to Cogeneration Corporation of America (CogenAmerica) for a $2.1
million gain after elimination of affiliate interest. The MCPC facility is a
110-MW, gas-fired power generation station located near Pryor, Oklahoma. NRG
owns 45.21 percent of the outstanding stock of CogenAmerica.

In December 1998, NRG and Dynegy signed agreements with San Diego Gas &
Electric Company to jointly acquire 1,218 MW of power generation facilities
located near Carlsbad and San Diego California for $356 million. NRG and Dynegy
will each own a 50% interest in these facilities. These transactions are
expected to close in the second quarter of 1999, pending regulatory approval.

In December 1998, NRG signed agreements with Niagara Mohawk Power to
purchase two coal fired power generation facilities located near Buffalo with a
combined summer capacity rating of 1,360 MW for $355 million. This transaction
is expected to close in the second quarter of 1999 pending regulatory approval.

In December 1998, the Company sold one half of its 50% interest in Enfield
Energy Center Limited (EECL) to El Paso International for $26.2 million
resulting in an after tax gain of $16.6 million. The Company continues to hold a
25% interest in EECL.

NOTE 5 -- 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.

A summary of NRG's significant equity-method investments which were in
operation at December 31, 1998 is as follows:

In accordance with Financial Accounting Standards No. 121 "Accounting for
Impairment of Long-lived Assets to be Disposed of," (SFAS 121), the Company
reviews long lived assets, investments and certain intangibles for impairment
whenever events or circumstances indicate the carrying amounts of an asset may
not be recoverable. During 1998, the Company wrote down accumulated project
development expenditures of $26.7 million. The Company's West Java, Indonesia,
project totaling $22.0 million was written off due to the uncertainties
surrounding all infrastructure projects in Indonesia. Also during 1998, the
Company wrote off its $1.9 million investment in the Sunnyside project and its
$2.8 million investment in Alto Cachopoal. The charge represents the difference
between the carrying amount of the investment and the fair value of the asset,
determined using discounted cash flow model. In December 1997, the Company
reviewed the carrying amount of the Sunnyside project that failed to restructure
its debt and recorded a charge of $8.9 million. The charge represents the
difference between the carrying amount of the investment and the fair value of
the asset, determined using a discounted cash flow model.

NOTE 6 -- RELATED PARTY TRANSACTIONS

SALE TO AFFILIATE

During October 1998, the Company sold its interest in the MCPC facility to
CogenAmerica for a $2.1 million gain after elimination of affiliate interest.
The MCPC facility is a 110 MW, gas-fired generation station located near Pryor,
Oklahoma. NRG owns 45.21 percent of the outstanding stock of CogenAmerica.

During December 1997, the Company sold its interest in the Millenium
facility, a 117 MW cogeneration plant under construction near Morris, Illinois
to CogenAmerica for $4.0 million.

OPERATING AGREEMENTS

NRG has two agreements with NSP for the purchase of thermal energy. Under
the terms of the agreements, NSP charges NRG for certain costs (fuel, labor,
plant maintenance, and auxiliary power) incurred by NSP to produce the thermal
energy. NRG paid NSP $5.1 million in 1998 and $4.6 million in 1997 under these
agreements.

NRG has a renewable 10-year agreement with NSP, expiring on December 31,
2001, whereby NSP agrees to purchase refuse-derived fuel for use in certain of
its boilers and NRG agrees to pay NSP a burn incentive. Under this agreement,
NRG received $1.4 million and $1.3 million from NSP, and paid $3.1 million and
$2.8 million to NSP in 1998 and 1997, respectively.

32
35

ADMINISTRATIVE SERVICES AND OTHER COSTS

NRG and NSP have entered into an agreement to provide for the reimbursement
of actual administrative services provided to each other, an allocation of NSP
administrative costs and a working capital fee. Services provided by NSP to NRG
are principally cash management, legal, accounting, employee relations, benefits
administration and engineering support. In addition, NRG employees participate
in certain employee benefit plans of NSP as discussed in Note 10. During 1998
and 1997, NRG paid NSP $5.2 million and $.7 million, respectively, as
reimbursement under this agreement.

In 1996, NRG and NSP entered into an agreement for NRG to provide
operations and maintenance services for NSP's Elk River resource recovery
facility and Becker ash landfill. During 1998 and 1997, NSP paid NRG $1.7
million and $1.1 million, respectively, as compensation under this agreement.

The Company has a credit agreement for $250 million of which $124 million
was outstanding at December 31, 1998. On March 17, 1998 NRG amended its existing
3-year, $175 million Revolving Credit facility to allow NRG additional borrowing
capacity under its covenant ratios. Also on that date, NRG entered into an
additional $75 million, 364-day facility with its existing bank group with ABN
as agent. The new facility is being used for general corporate purposes and for
funding future growth opportunities.

The Company had $33.6 million and $48.4 million in outstanding letters of
credit as of December 31, 1998 and 1997, respectively.

In March 1999, NRG filed a shelf registration with the SEC for up to $500
million in debt securities. The net proceeds will be used for general corporate
purposes, which may include financing the development and construction of new
facilities, working capital, debt reduction and pending or potential
acquisitions.

NOTE 9 -- INCOME TAXES

NRG and its parent, NSP, have entered into a federal and state income tax
sharing agreement relative to the filing of consolidated federal and state
income tax returns. The agreement provides, among other things, that (1) if NRG,
along with its subsidiaries, is in a taxable income position, NRG will be
currently charged with an amount equivalent to its federal and state income tax
computed as if the group had actually filed separate federal and state returns,
and (2) if NRG, along with its subsidiaries, is in a tax loss position, NRG will
be currently reimbursed to the extent its combined losses are utilized in a
consolidated return, and (3) if NRG, along with its subsidiaries, generates tax
credits, NRG will be currently reimbursed to the extent its tax credits are
utilized in a consolidated return.

</TABLE>

The effective income tax rate for the years 1998, 1997 and 1996 differs
from the statutory federal income tax rate of 35% primarily due to income and
expenses from foreign operations not subject to U.S. taxes (as discussed below)
and due to state tax, foreign tax, and tax credits as shown above.

Income before income taxes includes equity in net foreign investment income
of $29 million, $27 million and $28.0 million in 1998, 1997, and 1996
respectively. NRG's management intends to reinvest the earnings of foreign
operations indefinitely. Accordingly, U.S. income taxes and foreign withholding
taxes have not been provided on the earnings of foreign subsidiary companies.
The cumulative amount of undistributed earnings of foreign subsidiaries upon
which no U.S. income taxes or foreign withholding taxes have been provided is
approximately $158 million at December 31, 1998. The additional U.S. income tax
and foreign withholding tax on the unremitted foreign earnings, if repatriated,
would be offset in whole or in part by foreign tax credits. Thus, it is
impracticable to estimate the amount of tax that might be payable.

NOTE 10 -- BENEFIT PLANS AND OTHER POSTRETIREMENT BENEFITS

PENSION BENEFITS

NRG participates in NSP's noncontributory, defined benefit pension plan
that covers substantially all employees. Benefits are based on a combination of
years of service, the employee's highest average pay for 48 consecutive months,
and Social Security benefits. Plan assets principally consist of the common
stock of public companies, corporate bonds and U.S. government securities. NRG's
net annual periodic pension cost includes the following components:

The weighted average discount rate used in determining the actuarial
present value of the projected benefit obligation was 6.5% for December 31, 1998
and 7.0% for December 31, 1997. The rate of increase in future compensation
levels used in determining the actuarial present value of the projected
obligation was 4.5% in 1998 and 5.0% in 1997. The assumed long-term rate of
return on assets used for cost determinations was 8.5% for 1998 and 9.0% for
1997 and 1996.

Effective Jan. 1, 1998, NSP changed its method of accounting for subsidiary
pension costs under SFAS No. 87. The new method, which now allocates plan assets
based on subsidiary benefit obligations, was adopted to better match earnings on
total plan assets with the corresponding subsidiary benefit obligations. The
effect of this change decreased periodic pension costs by $2.9 million in 1998
from 1997 levels, including $1.3 million related to periods prior to the change.
The effects of this change have not been reported separately on the income
statement and prior periods have not been restated due to immateriality.

POSTRETIREMENT HEALTH CARE

NRG participates in NSP's contributory health and welfare benefit plan that
provides health care and death benefits to substantially all employees after
their retirement. The plan, which will terminate for nonbargaining employees
after 1998, is intended to provide for sharing of costs of retiree health care
between NRG and retirees. In 1994, NSP implemented a cost-sharing strategy, with
1997 and 1998 nonbargaining retirees paying 40 percent of total health care
costs. Cost-sharing for bargaining employees is governed by the terms of the
collective bargaining agreement.

Postretirement health care benefits for NRG are determined and recorded
under the provisions of SFAS No. 106, "Employers' Accounting for Postretirement
Benefits Other Than Pensions." SFAS No. 106 requires the actuarially determined
obligation for postretirement health care and death benefits to be fully accrued
by the date employees attain full eligibility for such benefits, which is
generally when they reach retirement age.

NRG's net annual periodic benefit cost under SFAS No. 106 includes the
following components:

The assumed health care cost trend rates used in measuring the accumulated
projected benefit obligation (APBO) at December 31, 1998 and 1997, were 8.1% and
9.2% for those under age 65, and 6.1 % and 6.8% for those over age 65,
respectively. The assumed cost trends are expected to decrease each year until
they reach 5.0% for both age groups in the year 2004, after which they are
assumed to remain constant. A one percent increase in the assumed health care
cost trend rate would increase the APBO by approximately $357 thousand as of
December 31, 1998. Service and interest cost components of the net periodic
postretirement cost would increase by approximately $78 thousand with a similar
one percent increase in the assumed health care cost trend rate. The assumed
discount rate used in determining the APBO was 6.5% for December 31, 1998 and
7.0% for December 31, 1997, compounded annually. The assumed long-term rate of
return on assets used for cost determinations under SFAS No. 106 was 8% for
1998, 1997 and 1996.

NRG EQUITY PLAN

Employees are eligible to participate in the NRG Equity Plan (the Plan).
The Plan grants phantom equity units to employees based upon performance and job
grade. NRG's equity units are valued based upon NRG's growth and financial
performance. The primary financial measures used in determining the equity
units' value are revenue growth, return on investment and cash flow from
operations. The units are awarded to employees annually at the respective year's
calculated share price (grant price). The Plan provides employees with a cash
pay out for the unit's appreciation in value over the vesting period. The Plan
has a seven year vesting schedule with actual payments beginning after the end
of the third year and continuing at 20% each year for the subsequent five years.

The Plan includes a change of control provision, which allow all shares to
vest if the ownership of NRG were to change.

NOTE 11 -- SALES TO SIGNIFICANT CUSTOMERS

NRG and the Ramsey/Washington Resource Recovery Project have a service
agreement for waste disposal, which expires in 2006. Approximately 26.5% in 1998
and 23.9% in 1997 of NRG's operating revenues

39
42

were recognized under this contract. In addition, sales to one thermal customer
amounted to 10.3% of operating revenues in 1998 and 9.9% of operating revenues
in 1997.

NOTE 12 -- FINANCIAL INSTRUMENTS

The estimated December 31 fair values of NRG's recorded financial
instruments are as follows:

<TABLE>

Long-term debt, including current portion........... 502,476 519,418 498,855 489,332
</TABLE>

For cash, cash equivalents and restricted cash, the carrying amount
approximates fair value because of the short-term maturity of those instruments.
The fair value of notes receivable is based on expected future cash flows
discounted at market interest rates. The fair value of long-term debt is
estimated based on the quoted market prices for the same or similar issues.

DERIVATIVE FINANCIAL INSTRUMENTS

To preserve the U.S. dollar value of projected foreign currency cash flows,
NRG hedges, or protects, those cash flows if appropriate foreign hedging
instruments are available. NRG hedges foreign currency transactions by using
forward foreign currency exchange agreements with terms of less than one to
three years. The gains and losses on those agreements offset the effect of
exchange rate fluctuations on NRG's known cash flows and anticipated cash flows.
NRG defers gains on agreement that hedge firm commitments of cash flows, and
accounts for them as part of the relevant foreign currency transaction when the
transaction occurs. NRG defers losses on these agreements the same way, unless
it appears that the deferral would result in recognizing a loss later.

While NRG is not currently hedging investments involving foreign currency,
NRG will hedge such investments when it believes that preserving the U.S. dollar
value of the investment is appropriate. NRG is not hedging currency translation
adjustments related to future operating results. NRG does not speculate in
foreign currencies. Before July 1997, NRG hedged investments involving foreign
currency as they were made to preserve their U.S. dollar value. Gains and losses
on those agreements offset the effects of exchange rate fluctuations on the
value of the investments underlying the hedges. Hedging gains and losses on
those agreements were reported, net of income tax effects, with other currency
translation adjustments as a separate component of stockholders' equity.

From time to time NRG also uses interest rate hedging instruments to
protect against increases in the cost of borrowing at both the corporate and
project level. NRG defers gains and losses on interest rate hedging instruments,
which are included and reported as part of the underlying equity investments.

As of December 31, 1998, NRG had one contract with a notional value of $2.8
million to hedge, or protect, foreign currency denominated future cash flows.
The effect of this contract on 1998 earnings was immaterial. This foreign
currency exchange contract expires in 1999. Management believes that NRG's
exposure to credit risk due to nonperformance by the counterparties to its
forward exchange contracts is insignificant, based on the investment grade
rating of the counterparties.

NRG has one interest rate swap agreement with a notional amount of $17.5
million. This swap was entered into with an existing variable rate debt issue.
The swap effectively converts the variable rate debt into fixed rate debt at
7.65 percent. If the swap had been discontinued on December 31, 1998, NRG would
have had to pay the counterparty approximately $0.9 million. The swap expires on
September 30, 2002.

NOTE 13 -- COMMITMENTS AND CONTINGENCIES

CONTINGENT REVENUES

NRG and its partner Dynegy each own a 50% interest in the Long Beach and El
Segundo generating stations ("California Projects"). During 1998, the first year
of deregulation of the state of California power industry, the California
Projects accrued certain receivables related to contingent revenues. These
revenues have been deferred pending resolution of the contingency. Such amounts
relate to items that are subject to contract interpretations, compliance with
processes and filed market disputes. The California Projects are actively
pursuing resolution and/or collection of these amounts, which totaled
approximately $60 million (NRG's share approximates $30 million) as of December
31, 1998. Upon any final resolution and/or collection of these amounts, such
deferred revenues will be recognized in NRG's equity income.

OPERATING LEASE COMMITMENTS

The Company leases certain of its facilities and equipment under operating
leases, some of which include escalation clauses, expiring on various dates
through 2010. Rental expense under these operating leases was $1.7 million in
1998 and $1.2 million in 1997. Future minimum lease commitments under these
leases for the years ending after December 31, 1998 are as follows:

CAPITAL COMMITMENTS -- INTERNATIONAL

NRG signed a Joint Development Agreement for the acquisition, upgrading,
expansion and development of Energy Center Kladno in Kladno, Czech Republic. The
acquisition of the existing facility is the first phase of a development project
that will include upgrading the existing plant and developing a new power
generation facility. NRG has made a $7.4 million commitment for the additional
facilities.

NRG is contractually committed to an additional equity investment of $7
million to Scudder Latin American Power II as of December 31, 1998.

NRG has a $10.6 million outstanding equity commitment for the Enfield
Energy Centre, a 396 MW power project under development in the North London
Borough of Enfield, England.

CAPITAL COMMITMENTS -- DOMESTIC

In 1998, NEO entered into Site Development and Coordination (SOC)
Agreements with a 50% owned affiliate. The SOC agreements provide for NEO to pay
the affiliate a flat, quarterly fee for operation, maintenance and development
support. Variable incentive payments based upon project performance are also
provided. The agreements are typically twenty years in duration with the bulk of
the payments for services being made prior to 2008. Total commitments under SOC
agreements amount to $36.5 million as of December 31, 1998.

In 1998, NEO entered into a Construction Management Services Agreement with
an affiliate. The agreement provides for NEO to manage the construction and/or
acquisition of nineteen electric generation facilities in the U.S. The agreement
provides for the payment of a management fee to NEO based upon the anticipated
future cash flows from the completed projects. If a project does not meet
certain performance

41
44

criteria, NEO will be required to purchase the project from the affiliate at an
agreed upon price. The total capital cost of the nineteen projects is expected
to be $127 million. As of December 31, 1998, ten of the projects with a capital
cost of $74 million had been completed and accepted by the affiliate. The
remaining projects are scheduled for completion in 1999.

In October 1998, NRG executed a binding purchase and sale agreement for $55
million with Eastern Utilities Associates to purchase the 229 MW Somerset
Station, of which 69 MW is on deactivated reserve. The project is expected to
financially close in the first quarter of 1999.

In February 1999, NRG purchased from Thermal Ventures, Inc. (TVI) the
remaining 50.1% limited partnership interests held by TVI in San Francisco
Thermal Limited Partnership and Pittsburgh Thermal Limited Partnership for $12.3
million. In addition, upon receipt of California and Pennsylvania regulatory
approval, NRG will acquire TVI's 50% 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.

NRG, together with two other parties and the Chapter 11 Trustee, have filed
a reorganization plan with the United States Bankruptcy Court to acquire the
fossil generating assets of Cajun Electric Power Cooperative of Baton Rouge,
Louisiana (Cajun) for approximately $1.2 billion. On February 11, 1999, the
Court issued an order denying confirmation of NRG's plan and the reorganization
plan proposed by a competing bidder. NRG along with its partners and the Trustee
are contemplating submitting a revised plan on April 16, 1999 to accommodate the
issues raised in the Court's February 11, 1999 decision. The Court has scheduled
hearings and activities to review the new plans in May and June 1999.

In December 1998, NRG and Dynegy signed agreements with San Diego Gas &
Electric Company to jointly acquire 1,218 megawatts of power generation
facilities located near Carlsbad and San Diego California for $356 million. NRG
and Dynegy will each own 50% interest in these facilities. This transaction is
expected to close in the first quarter of 1999.

In December 1998, NRG signed agreements with Niagara Mohawk Power to
purchase two coal fired power generation facilities located near Buffalo with a
combined summer capacity rating of 1,360 MW for $355 million. This transaction
is expected to close in the second quarter of 1999.

In January 1999, NRG executed a binding agreement with Consolidated Edison
Company of New York (ConEdison) to acquire the Astoria gas turbines facility and
the Arthur Kill Generating Station for $505 million. These facilities, which are
located in New York, have a combined summer capacity rating of 1,456 MW. This
transaction is expected to close in the second quarter of 1999.

In December 1997, NRG entered into a supplemental loan agreement to provide
up to $22.0 million to CogenAmerica to fund its capital contribution to a
project that was under construction. During 1998, NRG provided $12.0 million
under this agreement and expects to fund the remaining $10.0 million in 1999.

Also in 1996, NRG entered into an agreement requiring that it provide
CogenAmerica power generation investment opportunities in the United States over
a period of seven years. During the first three years of the seven-year term,
NRG is obligated to offer projects to CogenAmerica having aggregate, equity
value of at least $60 million or a minimum power generation capacity of 150 net
megawatts. In addition, NRG has committed to finance these "Co-Investment
Agreement" projects to the extent funds are not available to CogenAmerica on
comparable terms from other sources. During 1997, NRG provided CogenAmerica with
a 117 MW project and offered a 17 net MW project that CogenAmerica did not
purchase. During 1998 NRG provided CogenAmerica with a 110 MW project; thus
fulfilling the minimum requirements of the agreement.

NRG has guaranteed the repayment of certain affiliate borrowings under a
construction loan facility. The facility, which terminates in February 1999,
will fund construction of landfill gas collection and electric generation
projects. The loan facility commitment is $74.0 million. Accounts outstanding
under the facility at December 31, 1998, which could be subject to the NRG
guarantee if unpaid by affiliate, were $17.8 million.

NRG has contractually agreed to the monetization of certain tax credits
generated from landfill gas sales through the year 2007.

NRG anticipates funding its ongoing capital commitments through the
issuance of debt, additional equity from NSP, and operating cash flows.

CLAIMS AND LITIGATION

In the normal course of business, NRG is a party to routine claims and
litigation arising from current and prior operations. NRG is actively defending
these matters and does not feel the outcome of such matters would materially
impact the results of operation.

NOTE 14 -- SEGMENT REPORTING

Effective December 31, 1998, NRG adopted SFAS No. 131 -- Disclosures about
Segments of an Enterprise and Related Information. NRG conducts its business
within three segments: Independent Power Generation, Alternative Energy
(Resource Recovery and Landfill Gas) and Thermal projects. These segments are
distinct components of NRG with separate operating results and management
structures in place. The "Other" category includes operations that do not meet
the threshold for separate disclosure and corporate charges that have not been
allocated to the operating segments.
