AES Says Brazil will Cover Power Rationing Losses

LCG, Dec. 27, 2001--Global power company AES Corp. said this morning it reached an agreement with the Brazilian government that would let it recover its losses relating to electricityrationing in the power-starved country.

AES said the agreement applies to both its generation and distribution businesses in Brazil, and will be implemented through a price increase to final consumers. This agreement applies to the rationing-related loss of income incurred since the inception of rationing in June 2001 as well as any such losses that may occur in the future.

AES also said it reached an agreement with the Brazilian government that will eliminate delays in passing along costs. Price increases will be phased in over three to four years, the company said.

President Fernando Cardoso has issued an executive order putting the agreement onto effect. In accordance with this executive order, the Brazilian regulatory authority, ANEEL, authorized the necessary tariff increases today, the company said. The tariff increases are effective immediately.

Luiz David Travesso, an AES vice president, said "The success of our negotiations is a testament to the government of Brazil's desire to protect the economic value of our investments and to the durability of the contract-based regulatory structure in Brazil. The estimated net financial impact of this agreement is consistent with our expectations."
