PART I

ITEM 1. BUSINESS

(a) General development of business.

OVERVIEW

The AES Corporation and its subsidiaries and affiliates (collectively "AES"
or the "Company") are helping to meet the world's needs by providing electricity
to customers in many countries in a socially responsible way.

A majority of the Company's sales of electricity are made to customers
(generally electric utilities or regional electric companies) on a wholesale
basis for further resale to end users. This is referred to as the electricity
"generation" business. Sales by these generation companies are usually made
under long-term contracts from power plants owned by the Company's subsidiaries
and affiliates, although the Company does, in certain circumstances, make sales
into regional electricity markets without contracts. The Company's ownership
portfolio of power facilities includes new plants constructed for such purposes
("greenfield" plants) as well as existing power plants acquired through
competitively bid privatization initiatives and negotiated acquisitions.

AES now operates and owns (entirely or in part) a diverse portfolio of
electric power plants (including those within the integrated distribution
companies discussed below) with a total capacity of 24,076 megawatts ("MW"). Of
that total, 29% are fueled by coal or petroleum coke, 24% are fueled by natural
gas, 33% are hydroelectric facilities, 6% are fueled by oil, and the remaining
8% are capable of using multiple fossil fuels. Of the total MW, 5,025 (nine
plants) are located in the United States, 817 (eight plants) are in China, 1,818
(five plants) are in the U.K., 1,281 (three plants) are in Hungary, 6,456
(forty-one plants) are in Brazil, 885 (six plants) are in Argentina, 5,384
(seven plants) are in Kazakhstan (including 4,000 MW attributable to Ekibastuz
which currently has a reliable capacity of approximately 25%), 210 (one plant)
are in the Dominican Republic, 110 (one plant) are in Canada, 695 (two plants)
are in Pakistan, 405 (one plant) are in the Netherlands, 288 (one plant) are in
Australia, 282 (three plants) are in Panama (acquired in 1999) and 420 (one
plant) are in India (operational control acquired in 1999).

AES is also currently in the process of adding approximately 5,254 MW to
its operating portfolio by constructing several new plants. These include a 180
MW coal-fired plant, and a 700 MW natural gas-fired plant in the United States,
a 600 MW natural gas-fired plant in Brazil, a 2,100 MW coal-fired plant in
China, an 830 MW natural gas-fired plant in Argentina, a 360 MW coal-fired plant
in England, and a 484 MW natural gas-fired plant in Mexico.

As a result, AES's total MW of 96 power plants in operation or under
construction is approximately 29,330 and net equity ownership (total MW adjusted
for the Company's ownership percentage) represents approximately 19,819 MW.

AES also owns interests (both majority and minority) in companies that sell
electricity directly to commercial, industrial, governmental and residential
customers. This is referred to as the electricity "distribution" business.
Electricity sales by AES's distribution businesses are generally made pursuant
to the provisions of long-term electricity sale concessions granted by the
appropriate governmental authority as part of the original privatization of each
distribution company. In certain cases, these distribution companies are
"integrated", in that they also own electric power plants for the purpose of
generating a portion of the electricity they sell. Each distribution company
also purchases, in varying proportions, electricity from third-party wholesale
suppliers, including in certain cases, other subsidiaries of the Company.






AES has majority ownership in three distribution companies in Argentina,
one in Brazil, one in El Salvador, a heat and electricity distribution business
in Kazakhstan, one in the Republic of Georgia (operational control acquired in
1999) and less than majority ownership in three additional distribution
companies in Brazil. These ten companies serve a total of approximately 13.2
million customers with gigawatt hour sales exceeding 63,000. On a net equity
basis, AES's ownership represents approximately 3 million customers and gigawatt
hour sales exceeding 22,000.

AES has been successful in growing its business and serving additional
customers by participating in competitive bidding under privatization
initiatives and has been particularly interested in acquiring existing
businesses or assets in electricity markets that are promoting competition and
eliminating rate of return regulation. In such privatizations, sellers generally
seek to complete competitive solicitations in less than one year, much quicker
than the time periods associated with greenfield development, and usually
require payment in full on transfer. AES believes that its experience in
competitive markets and its worldwide integrated group structure, with its
significant geographic coverage and presence, enable it to react quickly and
creatively in such situations.

Because of this relatively quick process or other considerations, it may
not always be possible to arrange "project financing" (the Company's
historically preferred financing method, which is discussed further under Item
1(c), "Narrative description of business" below. Additionally, as in the past,
certain acquisitions or the commencement of construction in several greenfield
developments would potentially require the Company to obtain substantial
additional financing including both debt and equity.

The Company, a corporation organized under the laws of Delaware, was formed
in 1981. AES has its principal offices located at 1001 North 19th Street, Suite
2000, Arlington, Virginia 22209, and its telephone number is (703) 522-1315.

CAUTIONARY STATEMENTS AND RISK FACTORS

The Company wishes to caution readers that the following important
factors, among others, indicate areas affecting the Company which involve risk
and uncertainty (see also the Company's cautionary statements made in connection
with AES's Year 2000 efforts contained in its Discussion and Analysis of
Financial Condition and Results of Operations which is contained in its Current
Report on Form 8-K filed on March 18, 1999 (the "March 1999 Form 8-K"), which is
incorporated herein by reference). These factors should be considered when
reviewing the Company's business, and are relied upon by AES in issuing any
forward-looking statements. Such factors could affect AES's actual results and
cause such results to differ materially from those expressed in any
forward-looking statements made by, or on behalf of, AES. Some or all of these
factors may apply to the Company's businesses as currently maintained or to be
maintained.

o Changes in company-wide operation and plant availability (including
wholly and partially owned facilities) compared to the Company's
historical performance; changes in the Company's historical operating
cost structure, including but not limited to those costs associated
with fuel, operations, supplies, raw materials, maintenance and
repair, people, transmission of electricity and insurance.

o In certain non-U.S. countries where the Company is or is seeking to
conduct business: unexpected changes in electricity tariff rates or
tariff adjustments for increased expenses; the ability or inability of
AES to obtain, or hedge against, foreign currency; foreign exchange
rates and fluctuations in those rates; the economic, political and
military conditions affecting property damage, interruption of
business and expropriation risks; changes in trade, monetary and
fiscal policies, laws and regulations; other activities of
governments, agencies and similar organizations; social and economic
conditions; local inflation and monetary fluctuations; import and
other charges or taxes; conditions or restrictions impairing
repatriation of earnings or other cash flow; nationalizations and
unstable governments and legal systems, and intergovernmental
disputes.






o Changes in the amount of, and rate of growth in, AES's selling,
general and administrative expenses; the impact of AES's ongoing
evaluation of its development costs, business strategies and asset
valuations, including, but not limited to, the effect of a failure to
successfully complete certain development projects.
o Legislation intended to promote competition in U.S. and non-U.S.
electricity markets, such as those currently receiving serious
consideration in the United States Congress to repeal (i) the Public
Utility Regulatory Policies Act of 1978, as amended, or at least to
repeal the obligation of utilities to purchase electricity from
qualifying facilities, and (ii) the Public Utility Holding Company Act
of 1935, as amended; changes in regulatory rule-making by the Federal
Energy Regulatory Commission or other regulatory bodies; changes in
energy taxes; or new legislative or regulatory initiatives in non-U.S.
countries; changes in national, state or local environmental, safety,
tax and other laws and regulations applicable to the Company or its
operations.
o The prolonged failure by any customer of the Company or any of its
subsidiaries to fulfill its contractual payment obligations presently
or in the future, either because such customer is financially unable
to fulfill such contractual obligation or otherwise refuses to do so.
o Successful and timely completion of (i) the respective construction
for each of the Company's electric generating projects now under
construction and those projects yet-to-begin construction or (ii)
capital improvements to its existing facilities.
o Changes in inflation, fuel, electricity and other commodity prices in
U.S. and non-U.S. markets; conditions in financial markets, including
fluctuations in interest rates and the availability of capital; and
changes in the economic and electricity consumption growth rates in
U.S. and non-U.S. countries.
o Unusual weather conditions and the specific needs of each plant to
perform unanticipated facility maintenance or outages (including
annual or multi-year).
o The costs and other effects of legal and administrative cases and
proceedings, settlements and investigations, claims, and changes in
those items, developments or assertions by or against AES; the effect
of new, or changes in, accounting policies and practices and the
application of such policies and practices.
o Changes or increases in taxes on property, plant, equipment,
emissions, gross receipts, income or other aspects of the Company's
business or operations.

(b) Financial information about industry segments.

The Company considers its reportable segments to be electrical generation
and distribution. See note 12 to the consolidated financial statements
incorporated by reference to the Company's March 1999 Form 8-K.

(c) Narrative description of business.

The Company attempts to participate in competitive power markets as they
develop either through greenfield development or by acquiring and operating
existing facilities or systems in these markets. The Company operates electric
generating facilities that utilize natural gas, coal, oil, hydropower, or
combinations thereof. In addition, the Company participates in electricity
distribution and retail supply businesses and will continue to review
opportunities in such markets in the future. Other elements of the Company's
strategy include:

o Supplying energy to customers at the lowest cost possible, taking into
account factors such as reliability and environmental performance;
o Constructing or acquiring projects of a relatively large size
(generally larger than 100 megawatts);
o When available, entering into power sales contracts with electric
utilities or other customers with significant credit strength; and
o Where possible, participating in distribution and retail supply
markets that grant concessions with long-term pricing arrangements.






The Company also strives for operating excellence as a key element of its
strategy, which it believes it accomplishes by minimizing organizational layers
and maximizing company-wide participation in decision-making. AES has attempted
to create an operating environment that results in safe, clean and reliable
electricity generation and distribution. Because of this emphasis, the Company
prefers to operate all facilities which it develops or acquires; however, there
can be no assurance that the Company will have operating control of all of its
facilities.

The Company's focus is the wholesale generation and supply of electricity,
and electricity distribution businesses and integrated utilities. Asset
composition, operating margins and a variety of other business characteristics
differ significantly from one type of business to another. References to power
sales agreements, fuel supply agreements and plants generally mean those related
to the generation business. Concession (or service) contracts, supply contracts
and networks are generally associated with the distribution businesses.
Integrated utilities have characteristics of both businesses. In addition,
integrated utilities may generate more or less of their own electricity. For
example, Light (as defined below) generates a comparatively low percentage of
its own electricity while CEMIG (as defined below) generates almost all of its
own electricity needs.

Most of AES's electric generation plants sell electricity under long-term
power sales contracts. The Company attempts, whenever possible, to structure the
revenue provisions of its plants' power sales contracts such that changes in the
revenue components of these contracts correspond, as closely as possible, to
fluctuations in the cost components of the plant (primarily fuel costs). A
plant's revenues from a power sales contract usually consists of two components,
energy payments and capacity payments. Energy payments are based on a plant's
net electrical output (the amount of electricity delivered on a kilowatt-hour
basis), with payment rates usually indexed to the fuel costs of the contracting
utility or to general inflation indices. Capacity payments are based on either a
plant's net electrical output or its available capacity (the ratio of kilowatt
hours the plant delivers to the total kilowatt hours requested by the customer).
Capacity payment rates vary over the term of a power sales contract according to
various schedules.

To the extent possible, the Company attempts to structure an electric
generation plant's fuel supply contract so that fuel costs are indexed in a
manner similar to the energy payments a project receives under the power sales
contract. In this way, project revenues are partially hedged against
fluctuations in fuel costs.

As with fuel prices, AES has hedged a substantial portion of its projects
against the risk of fluctuations in interest rates. In each project with fixed
capacity payments, AES has attempted to hedge all or a significant portion of
its risk of interest rate fluctuations by arranging for fixed-rate financing or
variable-rate financing with interest rate swaps or other hedging mechanisms.
Those projects with fluctuating capacity payments are hedged by arranging for
floating rate financing.

The Company attempts to finance each domestic and foreign project primarily
under loan agreements and related documents which, except as noted below,
require the loans to be repaid solely from the project's revenues and provide
that the repayment of the loans (and interest thereon) is secured solely by the
capital stock, physical assets, contracts and cash flow of that project
subsidiary or affiliate. This type of financing is usually referred to as
"project financing." The lenders under these project financing structures
generally cannot look to AES or its other projects for repayment, unless such
entity explicitly agrees to undertake liability. AES has explicitly agreed to
undertake certain limited obligations and contingent liabilities, most of which
by their terms will only be effective or will be terminated upon the occurrence
of future events. These obligations and liabilities take the form of guarantees,
letter of credit reimbursement agreements, and, in certain circumstances,
agreements to pay to project lenders or other parties amounts up to the amounts
of distributions previously made by the applicable subsidiary or






affiliate to AES. To the extent AES becomes liable under guarantees and letter
of credit reimbursement agreements, distributions received by AES from other
projects are subject to the possibility of being utilized by AES to satisfy
these obligations. To the extent of these obligations, the lenders to a project
effectively have recourse to AES and to the distributions to AES from other
projects. The aggregate contractual liability of AES is, in each case, usually a
small portion of the aggregate project debt, and thus the project financing
structures are generally described herein as being "substantially non-recourse"
to AES and its other projects.

PRINCIPLES AND PRACTICES

A core part of AES's corporate culture is a commitment to "shared
principles." These principles describe how AES people endeavor to behave,
recognizing that they don't always live up to these standards. The principles
are:

Integrity - AES strives to act with integrity, or "wholeness." The Company
seeks to honor its commitments. The goal is that the things AES people say
and do in all parts of the Company should fit together with truth and
consistency.

Fairness - AES wants to treat fairly its people, its customers, its
suppliers, its stockholders, governments and the communities in which it
operates. Defining what is fair is often difficult, but the Company
believes it is helpful to routinely question the relative fairness of
alternative courses of action.

Fun - AES desires that people employed by the Company and those people with
whom the Company interacts have fun in their work. AES's goal has been to
create and maintain an environment in which each person can flourish in the
use of her or his gifts and skills and thereby enjoy the time spent at AES.

Social Responsibility - The Company believes that it has a responsibility
to be involved in projects that provide social benefits, such as lower
costs to customers, a high degree of safety and reliability, increased
employment and a cleaner environment.

AES recognizes that most companies have standards and ethics by which they
operate and that business decisions are based, at least in part, on such
principles. The Company believes that an explicit commitment to a particular set
of standards is a useful way to encourage ownership of those values among its
people. While the people at AES acknowledge that they won't always live up to
these standards, they believe that being held accountable to these shared values
will help them behave more consistently with such principles.

AES makes an effort to support these principles in ways that acknowledge a
strong corporate commitment and encourage people to act accordingly. For
example, AES conducts annual surveys, both company-wide and at each location,
designed to measure how well its people are doing in supporting these principles
- -- through interactions within the Company and with people outside the Company.
These surveys are perhaps most useful in revealing failures, and helping to deal
with those failures. AES's principles are relevant because they help explain how
AES people approach the Company's business. The Company seeks to adhere to these
principles, not as a means to achieve economic success but because adherence is
a worthwhile goal in and of itself.

In order to create a fun working environment for its people and implement
its strategy of operational excellence, AES has adopted decentralized
organizational principles and practices. For example, AES works to minimize the
number of supervisory layers in its organization. Most of the Company's plants
operate without shift supervisors. The project subsidiaries are responsible for
all







major facility-specific business functions, including financing and capital
expenditures. Criteria for hiring new AES people include a person's willingness
to accept responsibility and AES's principles as well as a person's experience
and expertise. The Company has generally organized itself into multi-skilled
teams to develop projects, rather than forming "staff" groups (such as a human
resources department or an engineering staff) to carry out specialized
functions.

BUSINESSES IN NORTH AMERICA

AES currently owns and operates, through subsidiaries and affiliates, ten
generation facilities in the United States and Canada representing approximately
5,135 MW.

Deepwater is a 143 MW petroleum coke-fired cogeneration facility located
near Houston, Texas. Fuel is supplied from the adjacent Lyondell Citgo refinery
under an all-requirements contract with Thyssen Citgo Petcoke Corp. that extends
through the end of the second quarter of 2000. The facility sells electricity
under two marketing agreements which expire December 31, 1999 to Dynegy
Marketing and Trade, and Williams Energy Marketing and Trade. Its remaining
output is delivered as available to Houston Lighting and Power Company under
Qualifying Facility tariffs. Thereafter Deepwater has committed essentially all
of its capacity under a contract with Texas Untilities Electricity Company for
the period January 1, 2000 through December 31, 2001. Although Deepwater
commenced commercial operation in 1986, making it the first of AES's commercial
plants, the Company did not gain control of the facility until 1995.

Beaver Valley is a 125 MW pulverized coal-fired cogeneration facility
located in Monaca, Pennsylvania. AES is the managing partner and operator of
Beaver Valley. West Penn Power Company purchases electricity produced by the
plant under a power sales contract with a remaining term of approximately 18
years. The facility sells steam to NOVA Chemicals Inc. for use in its chemical
processing activities under a requirements contract with a remaining term of
approximately four years.

Placerita is a 120 MW natural gas-fired, combined-cycle cogeneration
facility near Los Angeles, California. In December 1998, Placerita executed an
agreement to sell its power purchase agreement with Southern California Edison
("Edison")






for a lump-sum payment, completion of which is subject to approval by the
California Public Utilities Commission (the "CPUC"). If approved by the CPUC,
Placerita will use the proceeds of the sale to (i) redeem its project financing
loan and (ii) buyout its existing leveraged lease from Ford Motor Credit as well
as certain of the facility's existing steam and fuel contracts. Placerita
thereafter will sell electricity into the newly established California Power
Exchange.

Thames is a 181 MW coal-fired, circulating fluidized bed ("CFB")
cogeneration plant located in Montville, Connecticut. Power generated by Thames
is sold to Connecticut Light and Power Company under a contract with a remaining
term of approximately 16 years. Thames also sells steam to Stone Container
Paperboard Corporation for use in its recycled paperboard plant located adjacent
to the plant.

Shady Point is a 320 MW coal-fired, CFB cogeneration plant in LeFlore
County, Oklahoma. The Shady Point facility includes a 240-ton per day food
grade, liquid CO2 plant, which utilizes in its CO2 production processes
approximately 65,000 pounds per hour of process steam produced by the plant.
Shady Point sells electricity to Oklahoma Gas and Electric Company under a
contract with a remaining term of approximately 9 years.

Hawaii is a 180 MW coal-fired, CFB cogeneration plant located in Kapolei,
Oahu, Hawaii. Hawaii sells electricity to Hawaiian Electric Company, Inc. under
a contract with a remaining term of 25 years. Steam generated by the plant is
sold to Chevron USA Inc. for use in its oil refining operations under a steam
sales agreement with a remaining term of 15 years.

Kingston is a 110 MW gas-fired, combined-cycle cogeneration facility
located in Ernestown Township, Ontario. Kingston is owned by a partnership
comprised of AES and two partners, each owning 25 percent. The plant began
commercial operations in February 1997 and operates as a baseload facility.
Energy generated by the plant is sold to Celanese Canada, Inc. in the form of
steam and Dowthern. The Company operates the business through various agreements
entered into at the time of its acquisition of its interest in the facility.

AES Alamitos, AES Redondo Beach and AES Huntington Beach are natural
gas-fired facilities with a combined generating capacity of 3,956 MW located in
southern California. Each of the facilities sells its electricity to Williams
Energy Services Company ("Williams") pursuant to long-term tolling agreements.
Under the agreements, Williams delivers natural gas to the plants and owns and
markets the electrical output. AES completed its acquisition of the three
stations from Edison for approximately $786 million in May 1998 in association
with Edison's divestiture of the bulk of its generating capacity. In connection
with the acquisition, AES Southland, a wholly owned subsidiary of the Company,
obtained $713 million of non-recourse project financing. Pursuant to
California's electricity restructuring law, Edison will remain under contract to

San Nicolas is a 650 MW power plant in San Nicolas, Argentina. San Nicolas
sells a total of 345 MW of electricity (approximately 53 percent of the plant's
output capability) under two power






sales contracts, each with a remaining term of three years. Under the contracts
three distribution companies all of which are controlled by AES through its
ownership interest in Empresa Distribuidora de Energia Norte S.A. ("EDEN"),
Empresa Distribuidora de Energia Sur S.A. ("EDES") and Empresa Distribuidora de
La Plata S.A. ("EDELAP") (all described below), purchase 345 MW of electricity.
The plant sells additional electricity, when it is profitable to do so, into the
Argentine spot market.

Los Mina is a 210 MW oil-fired, simple-cycle power plant located in Santo
Domingo, Dominican Republic. Los Mina operates two simple-cycle combustion
turbine generators on land adjacent to a government owned electricity
substation, and supplies power to the interconnected grid of the Corporacion
Dominicana de Electricidad ("CDE"), the government-owned utility. The facility
burns oil supplied by Shell. The facility began operations in May 1996. Due to a
design flaw, Los Mina has experienced recurring turbine blade failure and was
out of service and unable to provide electricity in several instances during the
period prior to and after the date of AES's acquisition of the facility in 1997.
Modified blades have been installed in both of Los Mina's units and the
availability of the plant has reached 100% during 1998 and Los Mina is
processing claims with its insurer for recovery of the cost of repairs.
Furthermore, hurricane Georges caused a contractually defined force maejure
event to occur during the third quarter of 1998 which is affecting CDE's ability
to accept power from Los Mina. Although no assurance can be given that Los Mina
will be able to collect on the insurance claims, the Company believes that the
outcome of the matter will not have a material adverse effect on its
consolidated financial position, results of operation or cash flows.

Quebrada de Ullum is a 45 MW hydroelectric plant located on the San Juan
River in San Juan Province, Argentina. The Company acquired the facility and
began operations in April 1998 as part of a 40-year concession agreement it

sell their power pursuant to five-year contracts with local distribution
companies that were privatized in September 1998 (now owned by Union Fenosa and
Constellation). Thereafter, the units will sell their capacity and energy on the
spot market or under new contracts with the distribution companies. The Company
purchased EGE Chiriqui and EGE Bayano in January 1999






from Instituto de Recursos Hidraulicos y Electrificacion ("IRHE"), a
government-owned utility company in Panama, for approximately $91 million. The
Company owns 49% of both businesses with IRHE retaining a 49% share of the
companies and the remaining 2% to be owned by employees. Pursuant to an
agreement entered into as part of the acquisition, the Company controls both
businesses.

Light Servicos de Electricidade, S.A. ("Light") is a Brazilian electric
power generation, transmission and distribution system serving 28 municipalities
in the state of Rio de Janeiro, Brazil. Light is controlled by a consortium
comprised of AES, Electricite de France, Reliant Energy Industries, Inc.,
Houston Industries, Companhia Siderurgica Nacional and Banco Nacional de
Desenvolvimento Economico E Social (the "Light Consortium"). In connection with
the purchase of the controlling interest by the Light Consortium in 1996, the
Ministry of Mines and Energy of Brazil granted a 30-year concession to Light
which obligates Light to provide electric services to all customers within its
concession. Light generates about 16 percent of the total electricity it
distributes through four hydroelectric complexes having an aggregate installed
generating capacity of approximately 788 MW. Light purchases 53% of its
distributed electricity from Furnas Centrais Electricas S.A., a power generation
and transmission company owned by Eletrobras, and the remaining 31% is purchased
from Itaipu Binacional, a power generation company owned by the Republic of
Brazil and the Republic of Paraguay ("Itaipu"). AES has principal responsibility
within Light for all matters relating to the generation and purchase for
distribution of all electricity through its participation in the Light
Consortium.

Companhia Energetica de Minas Gerais ("CEMIG") is an integrated electric
utility serving the State of Minas Gerais in Brazil. Through a consortium
consisting of AES and two partners (the "CEMIG Consortium"), AES has significant
operating influence over CEMIG, including the right to appoint its chief
operating officer, and otherwise shares control of CEMIG with the State of Minas
Gerais. As it did with Light, the Ministry of Mines and Energy of Brazil granted
concessions to CEMIG pursuant to the terms of six concession agreements which
obligate CEMIG to provide electric services to all customers within its
concession, and authorizes CEMIG to charge its customers a tariff for electric
services. CEMIG transmits and distributes electricity, generated or purchased by
it, to substantially all areas in Minas Gerais. In addition to the approximately
5,668 MW of mostly hydroelectric power it generates through its interest in 37
facilities, CEMIG also purchases approximately 33% of its electricity sales from
Itaipu.

In the first quarter of 1999, the Governor of the State of Minas Gerais
formed a commission of inquiry charged with investigating whether the
privatization of CEMIG violates CEMIG's corporate statutes and whether the sale
process violated Minas Gerais or Brazilian federal law. A state legislative
committee and a commission of state attorneys currently are conducting hearings
on the matter. No action has been filed against AES or its partners in CEMIG and
AES has not had the opportunity to testify in front of the legislative committee
regarding its acquisition. In addition, there have been two suits filed against
the State of Minas Gerais in relation to the sale. The first attempts to set
aside the auction itself as being invalidly held and conducted and the second
questions the validity of the shareholders agreement under which AES acquired
its interest in CEMIG. Brazilian courts have rendered decisions in the second
suit that upholds the sale processes and the shareholders agreement. AES, the
CEMIG Consortium and CEMIG are not defendants in either of these suits.

Based on the Company's investigation of the items currently under review by
the legislative committee as well as the two claims, AES believes the auction
process and the shareholders agreement were and are in compliance with state and
federal law. If AES is named as a defendant in either of the cases or called to
testify by the legislative committee, it plans to vigorously defend its
acquisition of its interest in CEMIG. The Company believes that if the State of
Minas Gerais or a Brazilian court were to overturn the sale, the State would be
obligated to fully compensate AES.

EDEN and EDES are two privatized former state-owned Argentine distribution
companies. EDEN and EDES have 95-year territorial exclusive franchise

Comision Ejecutiva Hidroelectrica del Rio Lempa ("CEL"), a government-owned
utility company, in an auction held in January 1998. In May 1998, Energia Global
International, Ltd. purchased 20% of AES's interest in CLESA from AES for
approximately $15 million under an option agreement






negotiated during the acquisition. CLESA serves 188,000 customers and its area
of service borders Guatemala and Honduras to the north. CLESA purchases its
electricity in the local spot market and from CEL under an annual contract.

EDELAP is an electric distribution company located in the province of
Buenos Aires, Argentina. In June 1998, a subsidiary of AES acquired 90% of
EDELAP for approximately $355 million from a joint venture between Reliant

industrial firm. EDELAP serves approximately 278,000 customers in and around the
city of La Plata, the capital of Buenos Aires Province. EDELAP purchases
electricity it sells to retail customers from other generators, including AES's
San Nicolas. In November 1998, the Company sold one-third of its 90% interest in
EDELAP to a Public Service Enterprise Group, Inc. ("PSEG") subsidiary for
approximately $61 million and a proportionate percentage of related project
debt. The effect of the sale leaves AES with a 60% controlling interest in
EDELAP with a 30% interest owned by PSEG and the remaining 10% owned by an
EDELAP employee fund.

the process of arranging for project financing for AES Fifoots Point and expects
a closing to occur early in the second quarter of 1999. The Company can provide
no assurances, however, that the financing will occur and the project is subject
to a number of other risks including those relating to construction,
governmental approvals and project operational agreements.

AES Ironwood is a planned 700 MW natural gas-fired, combined cycle power
generating facility to be located in South Lebanon Township, Pennsylvania.
Originally slated to sell its output to affiliates of GPU Energy, the power
purchase agreements (the "PPAs") that AES Ironwood had executed with the
affiliates were terminated in December 1998. The termination occurred
automatically under the PPAs as a result of outstanding appeals associated with
the restructuring plans submitted to the Pennsylvania Utility Commission by GPU
Energy, which were not resolved by the date specified in the PPAs. In accordance
with the PPAs, GPU Energy reimbursed AES Ironwood approximately $31 million in
development fees, plus accrued interest, on December 31, 1998. In February 1999,
AES Ironwood executed a new PPA with Williams Energy Marketing and Trading
Company, a subsidiary of The Williams Company, Inc., for the entire output of
the planned 700 MW facility. The PPA is a twenty-year tolling arrangement under
which AES Ironwood will provide capacity and fuel conversion services, and
Williams will supply the fuel, and will own and market the power output. AES
Ironwood began preliminary construction in 1998 and plans for commencement of
commercial operation in 2002.

PROJECTS IN ADVANCED STAGES OF DEVELOPMENT

The Company currently is pursuing over 100 new business opportunities in
various stages of development. Successful completion of each of these projects
are subject to numerous risks as discussed elsewhere in this Annual Report on
Form 10-K, and no assurance can be given that any of the projects or businesses
will be completed or acquired. Listed below are development projects that have
achieved certain milestone objectives the Company deems significant.

San Francisco Energy Company, L.P. ("SFEC") is developing a 240 MW natural
gas-fired facility to be located in San Francisco, California. SFEC is a joint
venture between AES Pacific, Inc., which is a subsidiary of the Company and the
general partner in SFEC, and Sonat Inc. SFEC signed a Standard Offer Contract in
1994 with Pacific Gas & Electric ("PG&E") as the winner of the San Francisco
portion of the California Public Utilities Commission's ("CPUC") Biennial
Resource Plan Update ("BRPU"). The contract calls for the full capacity of the
plant to be purchased by PG&E for 30 years, with an option to terminate after 17
years. However, a ruling by the Federal Energy Regulatory Commission ("FERC")
has questioned the validity of the BRPU process, pursuant to which SFEC was
awarded its contract. The Company believes that SFEC's contract with PG&E is
valid, but the Company is currently involved in a regulatory proceeding before
the CPUC with PG&E over the validity of the contract. The Company does not
believe that the ultimate resolution of this matter will have a material adverse
effect on the Company. Substantial risks to the successful completion of this
project exist, including those relating to the regulatory proceedings, project
siting, financing, construction and permitting.

AES has been developing AES Puerto Rico which is to be a 454 MW coal-fired
cogeneration facility in Guayama, Puerto Rico. The Puerto Rico Electricity Power
Authority has agreed to purchase the electrical output of the facility pursuant
to a 25-year power sales agreement. The project originally received approval of
its environmental impact statement from the Puerto Rico Environmental Quality
Board, but that approval was challenged. In June 1998, the Puerto Rico Supreme
Court ruled in favor of the project on an appeal to its environmental impact
statement. The environmental impact statement approval is now final and
unappealable. The project received its Prevention of Significant Deterioration
permit from the U.S. Environmental Protection Agency (the "EPA") in September of
1998 and that permit is currently under appeal with the EPA's Environmental
Appeals Board.






AES also has been developing a 500 MW coal-fired facility in the State of
Orissa, India ("Ib Valley"). Ib Valley has been re-configured and therefore
re-permitted over the past two years. Ib Valley signed an amended power purchase
agreement with the Grid Corporation of Orissa in 1998 and a new sovereign
payment guarantee is expected to be executed in the near future.

In January 1998, the Company was selected by the Government of Bangladesh's
Ministry of Energy and Mineral Resources as the winning bidder to build, own and
operate a 360 MW (net) gas-fired combined cycle power plant at a site near
Dhaka, Bangladesh ("Haripur"). Haripur is expected to commence commercial
operations in the year 2000, and electricity will be sold to the Bangladesh
Power Development Board under the terms of a 22-year power purchase agreement.

Also, in June 1998, the Government of Bangladesh selected the Company as
the First-Ranked Sponsor to build, own and operate a 450 MW (net) gas-fired
combined cycle power plant at a site near Dhaka, Bangladesh on the Meghna River
(the "Meghnaghat Project"). The site is about three miles from AES's Haripur
project. Electricity from the Meghnaghat Project is anticipated to be sold to
the Bangladesh Power Development Board under the terms of a 22-year power
purchase agreement, which is expected to be signed shortly. Commercial
operations of the Meghnaghat plant is expected to commence in the year 2000.
Titus Gas Transmission and Distribution Company, a subsidiary of Petrobangla,
will supply natural gas to the facility from a nearby pipeline for the term of
the power purchase agreement.

In August 1998, the Company won a bid to acquire six coal-fired, electric
generating plants from NGE Generation, Inc., an affiliate of New York State
Electric & Gas Corporation ("NYSEG"), for approximately $950 million. The
facilities represent the bulk of NYSEG's coal-fired generation assets and were
auctioned as part of NYSEG's implementation of its restructuring plan in
accordance with New York's introduction of wholesale and retail competition into
the state's electricity generation market. The six facilities, located in
western and west-central New York, are the 675 MW Kintigh facility (AES
Somerset), the 306 MW Milliken facility (AES Cayuga), the 126 MW Goudey facility
(AES Westover), the 161 MW Greenidge facility (AES Greenidge), the 85 MW
Hickling facility (AES Hickling) and the 71 MW Jennison facility (AES Jennison).
The facilities include low-cost generating plants and, with the exception of
some of the smaller units, are expected to run as based-load units in a
competitive New York electricity generation market. Sulfur dioxide scrubbers
have already been installed at the largest plants, Kintigh and Milliken. The
acquisition is expected to be completed during the second quarter of 1999 and is
subject to customary closing conditions, including the receipt of various
governmental approvals.

In November 1998, an agency of the Government of Sri Lanka selected the
Company as the preferred bidder to develop a 160 MW combined-cycle power plant
to be located at Kelanitissa, Sri Lanka. A letter of intent has been issued by
the Government of Sri Lanka to a new company, AES Kelanitissa Private Limited,
formed by a consortium led by AES and Hayley's Engineering Ltd, the local
minority partner. AES will build, own, operate and transfer ("BOOT") the power
plant under a concession that would be valid for a period of 20 years, with the
facility's electrical output sold into the national grid. It is expected that
the open cycle mode of the plant will reach 100 MW capacity by the end of 2000,
with capacity increasing to 160 MW at commencement of combined cycle operations
thereafter in 2001.

In November 1998, the Company and CILCORP Inc. agreed to terms on a
definitive agreement under which AES will acquire all of CILCORP's 13,610,680
common shares at a price of $65 per share, or approximately $885 million.
CILCORP was formed in 1985 and is headquartered in Peoria, Illinois. CILCORP is
an energy services company whose largest subsidiary, CILCO, is an 85 year-old
natural gas and electric utility serving approximately a quarter of a million
retail customers in central Illinois. In






1997, CILCORP had consolidated revenues of $976 million and net assets of $1.3
billion. CILCORP and its subsidiaries employ approximately 1,800 people and
operate two coal-fired generating facilities with a combined capacity of 1150
megawatts.

The transaction, under which CILCORP will become a wholly-owned subsidiary
of AES, requires the approval of CILCORP shareholders, which is expected to
occur in the second quarter of 1999. The acquisition is subject to review by the
Federal Energy Regulatory Commission ("FERC"), the Illinois Commerce Commission
("ICC"), the Securities and Exchange Commission ("SEC"), the United States
Department of Justice ("DOJ"), and the Federal Trade Commission ("FTC"). The
project has passed review by the ICC, DOJ and the FTC. The Company expects the
transaction to be completed by mid-1999, subject to ongoing review by the FERC
and the SEC.

In January 1999, the Company was selected by Florida's Orlando Utilities
Commission ("OUC") to enter into exclusive negotiations with OUC to purchase its
Indian River Steam Electric Plant. The Indian River Plant is a 610 MW facility
burning oil and natural gas, located in Titusville, Florida. The plant consists
of three steam turbines that were built in the 1970s. Recently, the OUC has
informed the Company that it is also negotiating with other bidders. The
successful completion of this transaction is subject to a number of conditions,
including certain regulatory approvals and the negotiation and execution of
definitive documentation.

In February 1999, a subsidiary of the Company was selected by the Hungarian
utility, the MVM, to build, own and operate a 190 MW gas-fired combined cycle
power plant at the site of one of AES's existing power plants in Tiszaujvaros,
located in eastern Hungary (the "Phoenix Project"). Electricity from Phoenix
Project will be sold to the MVM under the terms of a 15-20 year power purchase
agreement, that is expected to be signed during the second quarter of 1999.
Commercial operation of the Phoenix plant is expected to commence in the year
2004. Fuel for the facility will either come from a nearby pipeline owned by the
Hungarian oil and gas company, MOL or from Gazprom. Successful completion of
this transaction is subject to a number of conditions, including financing,
permits and other government approvals.

In March 1999, the Company won a bid to acquire Ecogen Energy which
operates two gas-fired power stations in Victoria, Australia for approximately
A$350 million. The power stations, Newport and Jeeralang, have a total capacity
of 966 MW. Successful completion of the transaction remains subject to the
transfer of various approvals and licenses.

REGULATORY OUTLOOK

Currently eighteen states in the United States have passed legislation that
permit utility customers to choose their electricity supplier in a competitive
electricity market (so-called "retail access" or "customer choice" laws), and
all but two of the remaining states are considering such legislation. While such
"customer choice" plans differ in detail, they usually share important elements:
(1) they allow customers to choose their electricity suppliers by a certain date
(the dates in the existing or proposed legislation vary between 1998 and 2003);
(2) they allow utilities to recover so-called "stranded costs"--the remaining
costs of uneconomic generating or regulatory assets; and (3) they reaffirm the
validity of existing QF contracts, and make provisions to assure payment over
the contract life.

In order to guarantee payment of utilities' costs and the costs of QF
contracts, some states have used or are proposing to use financial methods to
"securitize" these payments. The "securitization" process might involve the
following steps: first, the financial obligations to be "securitized" would be
legally affirmed through legislation. This legal obligation then is used to
borrow money in public debt markets to pay off the obligation. The legal
obligation allows the borrower to obtain a good credit rating and therefore a
lower interest rate. In some cases, the benefits of the lower interest rate are
passed on to retail electric customers (perhaps in the form of a rate decrease).
"Securitization" of QF contract obligations, if applied to AES contracts in the
future, would significantly reduce the risk to AES that its power sales
contracts would not be honored due to potential financial difficulties of the
utility purchaser.

In addition to state restructuring legislation, members of Congress have
proposed new federal






legislation to encourage customer choice and recovery of stranded assets. Some
argue that federal legislation is needed to avoid the "patchwork" effect of each
state acting separately to pass restructuring legislation; others argue that
each state should decide whether to allow retail choice. In 1997 several bills
were (and others are expected to be) submitted to Congress on electricity
restructuring. While it is uncertain whether or when federal legislation dealing
with electricity restructuring might be passed, it is the opinion of the Company
that such legislation would not have a materially adverse effect on the
Company's U.S. business.

In addition to the federal restructuring legislation proposals, a number of
bills have been proposed by members of Congress to repeal all or portions of
PURPA and/or PUHCA--as separate legislation if a comprehensive restructuring
bill fails to pass. The Company believes that the repeal of PURPA and/or PUHCA
is unlikely (and inappropriate) unless it is a part of a comprehensive
restructuring bill.

In anticipation of restructuring legislation, many U.S. utilities are
seeking ways to lower their costs in order to become more competitive. These
include the costs that utilities are required to pay under QF contracts, which
the utilities may view as excessive when compared to current market prices. Many
utilities are therefore seeking ways to lower these contract prices by
renegotiating the contracts, or in some cases by litigation. While the Company
is generally open to renegotiation of existing contracts, it believes that the
aforementioned electricity market restructuring legislation will likely reduce
both the pressure to renegotiate and the need for such contract renegotiations.

Despite the recent movement toward electricity restructuring, electricity
markets in the United States are still heavily regulated. United States laws and
regulations still govern to some extent wholesale electricity transactions, the
type of fuel utilized, the type of energy produced, and power plant ownership.
State regulatory commissions have jurisdiction over retail electricity
transactions. United States power projects also are subject to laws and
regulations controlling emissions and other substances produced by a plant and
the siting of plants. These laws and regulations generally require that a wide
variety of permits and other approvals be obtained before the construction or
operation of a power plant commences, and that the facility operate in
compliance with these permits thereafter. FERC must also approve rates charged
by certain power marketers such as those of the Company's subsidiary, AES Power.

In the United States, so-called Qualifying Facilities ("QFs") are relieved
of compliance with extensive federal, state and local regulations by the
provisions of the Public Utility Regulatory Policies Act, as amended ("PURPA").
Each of AES's current domestic plants is a QF. Loss of QF status, if not
prevented, would subject these plants to more extensive regulations. The Company
believes, however, that it will usually be able to react in a manner that would
avoid the loss of QF status.

AES must obtain exemptions from, or become subject to regulation by, the
Securities and Exchange Commission under the Public Utility Holding Company Act
("PUHCA") in regard to both its domestic and foreign utility company holdings.
There are a number of exemptions from PUHCA that are available for both domestic
and foreign utility company owners, including those for QFs, Exempt Wholesale
Generators and Foreign Utility Companies. AES has obtained, and believes that it
will be able to obtain and maintain in the future, appropriate PUHCA exemptions
for its utility acquisitions although no assurances can be given.

In addition, as one of the Company's major non-U.S. markets, changes in
Brazilian regulatory structures will have an impact on the Company. The
electricity industry in Brazil is regulated by the Brazilian federal government,
acting through the Ministry of Mines and Energy, which has exclusive authority
over the electricity sector through regulatory powers assigned to it. This
sector is currently in a state of rapid change in Brazil. For example, pursuant
to a federal law enacted in 1996, regulatory policy






for the sector, which was implemented by the Departmento Nacional de Aguas e
Energia Eletrica ("DNAEE"), is now implemented by a new autonomous national
electric energy agency (Agencia Nacional de Energia Eletrica or "ANEEL"). ANEEL
is an independent regulatory agency and to delegate certain functions to
agencies based in certain states of Brazil. However, ANEEL cannot delegate any
authority regarding tariffs to state agencies.

ANEEL is responsible for (i) granting and supervising concessions for
electricity generation, transmission and distribution, including approval of
applications for the setting of electricity tariffs; (ii) supervising and
performing financial examinations of the concessionary companies; (iii) issuing
regulations for the electricity sector; and (iv) planning, coordinating and
executing water resource studies and granting and supervising concessions for
the use of water resources. Due to electricity tariffs' significant weight in
the measurement of national inflation, tariff increases have been controlled by
the Ministry of Finance, although it is not its official responsibility.

In addition to the powers currently granted to DNAEE, ANEEL has the
following responsibilities: (i) to implement and regulate the exploitation of
electric energy and the use of hydroelectric power pursuant to the Power Sector
Law; (ii) to promote the bidding process for the granting of new concessions;
(iii) to solve administrative disputes among utilities, IPP companies,
self-producers and customers; and (iv) to determine the criteria for the
establishment of the cost of the transmission of energy pursuant to the Power
Sector Law. Nevertheless, until regulations regarding the implementation of
ANEEL are promulgated, DNAEE will continue to monitor and regulate the Brazilian
electricity sector.

UNITED STATES ENVIRONMENTAL REGULATIONS

The construction and operation of power projects are subject to extensive
environmental and land use regulation. In the United States those regulations
applicable to AES primarily involve the discharge of effluents into the water,
emissions into the air and the use of water, but can also include wetlands
preservation, endangered species, waste disposal and noise regulation. These
laws and regulations often require a lengthy and complex process of obtaining
licenses, permits and approvals from federal, state and local agencies. If such
laws and regulations are changed and AES's facilities are not "grandfathered"
(that is, made exempt by the fact that the facility pre-existed the law) or
otherwise are not excluded, extensive modifications to a project's technologies
and facilities could be required. If environmental laws or regulations were to
change in the future, there can be no assurance that AES would be able to
recover all or any increased costs from its customers or that its business and
financial condition would not be materially and adversely affected. In addition,
the Company may be required to make significant capital or other expenditures in
connection with such changes in environmental laws or regulations. While AES
expects that environmental and land use regulations in the United States will
continue to become more stringent over time, the Company is not aware of any
currently planned changes in law that would result in a material adverse effect
on its consolidated financial position.

Clean Air Act. The original Clean Air Act of 1970 set guidelines for
emissions standards for major pollutants (e.g. SO2 and NOx) from newly-built
sources. In late 1990, Congress passed a set of amendments to the Clean Air Act
(the "1990 Amendments"). All of AES's domestic operating plants perform at
levels better than federal emission standards mandated for such plants under the
Clean Air Act (as amended). The 1990 Amendments attempt to reduce acid rain
precursor emissions (SO2 and NOX) from existing sources -- particularly large,
older power plants that were exempted from certain regulations under the
original Clean Air Act. Because AES's facilities are relatively new cogeneration
units with low air emissions that qualify as "existing sources" under the 1990
Amendments, they have been "grandfathered" from certain acid rain compliance
provisions of the 1990 Amendments. Other provisions of the Clean Air Act related
to the reduction of ozone precursor emissions (VOC and NOx) have triggered "
reasonably available control technology" ("RACT") requirements by various states
to






reduce such emissions.

The hazardous air pollutant provisions of the 1990 Amendments presently
exclude electric steam generating facilities such as AES's domestic plants;
however, the 1990 Amendments directed that the Environmental Protection Agency
("EPA" or the "Agency") prepare a study on hazardous air pollutant ("HAP")
emissions from power plants. In the fall of 1996, EPA released an interim report
on HAP emissions from power plants that tentatively concluded that the risk of
contracting cancer from exposure to HAPs (except mercury) from most plants was
very low (less than one in 1 million). EPA is developing a separate study on
mercury emissions from power plants. The draft mercury study report is currently
being reviewed by the federal Scientific Advisory Board and it is not certain
when a final report will be released. A final comprehensive HAP report with
recommendations is expected to be issued after EPA's review of mercury emissions
from power plants is complete. If it is determined that mercury from power
plants should be regulated, the use of "maximum available control technology"
("MACT") for mercury (which is now not subject to regulation) could be required.

In 1997, EPA published new rules that tighten ambient air quality standards
for ozone and small particulate matter (so-called PM 2.5). These new standards
increase the number of so-called "nonattainment regions" for ozone and
particulates. If new ozone and particulate matter nonattainment areas are
created, AES's plants may be faced with further emission reduction requirements
that could necessitate the installation of additional control technology.

In order to make further improvements in air quality in the eastern United
States, EPA in 1997 issued a call for states to revise their "state
implementation plans" (SIPs) for ozone precursors--primarily NOX. EPA
recommended further reductions of up to 65% for some states, depending on local
conditions. As a result, AES will be required to make further reductions in NOX
emissions at its Beaver Valley plant in Pennsylvania (AES's other plants have
emission levels well below baseline levels).

The Company does not believe that any of the potential additional
requirements discussed above will have a material adverse effect on its results
of operations and consolidated financial position.

Hazardous Waste Regulation. Based on a 1988 study, EPA has decided not to
regulate most coal combustion ash as a hazardous waste; however, EPA reserved
making a decision with respect to coal ash from fluidized bed combustion (the
burning of coal in the presence of limestone), which is still being evaluated by
the Agency. AES, along with other CFB owners and manufacturers, is currently
participating in a study to evaluate whether or not CFB ash should be classified
as hazardous. EPA is required to make a determination on whether to regulate CFB
ash in 1998. If EPA decides to regulate fluidized bed coal ash as a hazardous or
special waste, AES could incur additional ash disposal costs to dispose of ash
from its plants that utilize fluidized bed boilers.

FOREIGN ENVIRONMENTAL REGULATIONS

AES now has ownership interests in operating power plants and distribution
companies in many countries outside the United States. Each of these countries
and the localities therein have separate laws and regulations governing the
siting, permitting, ownership and power sales from AES's plants. These laws and
regulations are often quite different than those in effect in the United
States--and AES's non-U.S. businesses have been in substantial compliance with
these different laws and regulations. In addition, projects funded by the World
Bank are subject to World Bank environmental standards, which may be more
stringent than local country standards but are typically not as strict as U.S.
standards. Whenever feasible, AES attempts to use advanced environmental
technologies (such as CFB coal technology or advanced gas turbines) in order to
minimize environmental impacts.

Based on current trends, AES expects that environmental and land use
regulations affecting its






plants located outside the United States will likely become more stringent over
time. This appears to be due in part to a greater participation by local
citizenry in the monitoring and enforcement of environmental laws, better
enforcement of applicable environmental laws by the regulatory agencies, and the
adoption of more sophisticated environmental requirements. If foreign
environmental and land use regulations were to change in the future, the Company
may be required to make significant capital or other expenditures in order to
comply. There can be no assurance that AES would be able to recover all or any
increased costs from its customers or that its business, financial condition or
results of operations would not be materially and adversely affected by future
changes in foreign environmental and land use regulations.

EMPLOYEES

At December 31, 1998, AES and its subsidiaries employed approximately
11,700 people. The total number of people employed in facilities which AES
operates or has an equity interest in is approximately 39,400.

Sales.

See the information contained in Note 12 to the consolidated financial
statements of the Company contained in the March 1999 Form 8-K, such information
being incorporated herein by reference.


ITEM 2. PROPERTIES

Offices are maintained by the Registrant in many places around the world
which are generally occupied pursuant to the provisions of long- and short-term
leases, none of which is material to the Company. With a few exceptions, the
Registrant's facilities which are described in Item 1 hereof are subject to
mortgages or other liens or encumbrances as part of the related project
financings. The land interest held by the majority of the facilities is that of
a lessor or, in the case of the facilities located in the People's Republic of
China, a land use right that is leased or owned by the related joint venture
that owns the project. However, in a few instances there exists no accompanying
project financing for the facility and in a few of these cases the land interest
may not be subject to any encumbrance and is owned by the subsidiary or
affiliate owning the facility outright.






ITEM 3. LITIGATION.

The Company is involved in certain legal proceedings in the normal course
of business. It is the opinion of the Company that none of the pending
litigation is expected to have a material adverse effect on its results of
operations or financial position.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

No matter was submitted to a vote of security holders during the fourth
quarter of 1998.

PART II

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS.

Exchange (NYSE) under the symbol "AES". The following tables set forth the high

indicated.

(b) Holders.

As of March 3, 1999, there were 1,091 registered holders of the
Registrant's Common Stock, par value $0.01 per share.

(c) Dividends.

Under the terms of the Company's $600 million corporate revolving loan and
letters of credit facility entered into with a commercial bank syndicate, the
Company is currently prohibited from paying cash dividends. In addition, the
Registrant is precluded from paying cash dividends on its Common Stock under the
terms of a guaranty to the utility customer in connection with the AES Thames
project in the event certain net worth and liquidity tests of the Registrant are
not met. The Registrant has met these tests at all times since making the
guaranty.

The ability of the Registrant's project subsidiaries to declare and pay
cash dividends to the Registrant is subject to certain limitations in the
project loans and other agreements entered into by such project subsidiaries.
Such limitations permit the payment of cash dividends out of current cash flow
for quarterly, semiannual or annual periods only at the end of such periods and
only after payment of principal and interest on project loans due at the end of
such periods, and in certain cases after providing for debt service reserves.

(1) For the purposes of this ratio, earnings include income before taxes
and fixed charges excluding capitalized interest. Fixed charges include
interest, whether capitalized or expensed, and amortization of deferred
financing costs, whether capitalized or expensed. Due to the project specific
nature of the Company's construction financing, fixed charges on most projects
in construction are funded with proceeds from project finance borrowings and do
not require the use of funds from operations. If such construction-related fixed
charges had been excluded in calculating the ratio of earnings to fixed charges,
such ratios would have been 2.10x, 2.23x, 2.03x, 1.69x, and 1.92x for the five
years ended December 31, 1998, respectively.
