Reliant Completes Sale of Brazilian Interests

LCG, Dec. 8, 2000--Reliant Energy Inc. said yesterday that it has completed the sale of its interest in Light Servicos de Eletricidade S.A. to AES Corp. of the U.S. and EdF International S.A., a subsidiary of French utility Electricit de France, for $430 million.

An AES subsidiary purchased about 30 percent of Reliant Energy's shares in Light, while EdF bought the remainder. Light and its subsidiary, Eletropaulo Metropolitana Eletricidade de Sao Paulo S.A., together serve some 7.4 million customers in Rio de Janeiro and Sao Paulo, Brazil.

A consortium including Reliant, AES and EdF purchased a majority interest in Light when the Brazilian government privatized the company in 1996. Reliant's interest in Light, which amounted to about 11.7 percent, is what AES and EdF acquired.

The Light investment represented Reliant Energy's entire interest in Brazil. The sale is part of thecompany's plan, announced a year ago, to divest its Latin American investments, which are primarily regulated energy delivery businesses, in order to focus on its competitive energy services businesses in the U.S. and Western Europe.

Reliant said the sale of its remaining investment in Colombia is expected to close by the end of the year, completing the divestiture of the "vast majority" of the company's Latin American investments.
