AES Announces Plans to Expand Electricity Service in Cameroon.

Secures $340 Million in Non-Recourse Financing to More Than Double Number of People Served

ARLINGTON, Va. -- The AES Corporation (NYSE: AES) announced today that its subsidiary, AES SONEL, plans to expand its electricity network in Cameroon, more than doubling the number of people it currently serves over the next 15 years and extending its network to previously unserved parts of the country. The improvements are part of an amended concession agreement AES SONEL has reached with the Government of Cameroon. AES also announced that AES SONEL secured a $340 million ([euro]260 million) financing package--one of the largest ever provided to a privatized utility in Sub-Saharan Africa--to finance a majority of these system improvements.

AES SONEL expects to add approximately 50,000 new electricity connections each year over the next 15 years. The company also plans to upgrade its existing transmission, distribution and generation facilities. AES SONEL is the sole electric utility in Cameroon and currently generates and distributes electricity to more than 528,000 customers in the country.

"This is the most ambitious expansion program for Cameroon's electricity sector. We expect to more than double the number of people we serve in Cameroon and to provide electricity to thousands of individuals who never had it before," said John McLaren, President of AES's Europe, CIS and Africa region. "AES SONEL is committed to improving Cameroon's energy sector, which is essential to the country's continued economic development and we're pleased to move forward with the government under our amended concession agreement."

Since AES acquired SONEL in 2001, AES has significantly expanded the country's back-up power generation capacity in Cameroon. In 2004, AES SONEL finalized construction and began operation of an 85 MW thermal power plant, called Limbe, which has increased the country's available generating capacity in the dry season by approximately 20%.

"Over the last six years, we have steadily improved and expanded electricity generation and distribution across Cameroon," said Jean David Bile, CEO of AES SONEL. "Under our investment program, we will continue to improve the reliability and efficiency of our generation, transmission and distribution systems. We thank the Government of Cameroon for its support of AES SONEL and the development of the country's power sector, and for the continued support of the development banks."

The 13-year $340 million financing was provided by a syndicate comprising eight developmental finance institutions, which includes the International Finance Corporation (IFC), the European Investment Bank, African Development Bank, the Central African Development Bank, DEG - Deutsche Investitions-und Entwicklungsgesellschaft mbH, the Emerging Africa Infrastructure Fund, FMO - The Netherlands Development Finance Company and Proparco.
