AES Enters Electric Transmission Business in North America.

Partners with Trans-Elect's Development Team as Part of Growth Strategy

ARLINGTON, Va. -- The AES Corporation (NYSE:AES) today announced that it is entering the electric transmission business as part of its overall growth strategy for North America. Through a new wholly-owned subsidiary, AES said it has acquired the development pipeline and trade name from Trans-Elect, LLC, a leading transmission developer. In addition, AES announced that the new subsidiary has entered into an agreement with Trans-Elect's former management team to jointly develop projects across North America to extend and improve the nation's electricity grid.

"We see significant potential for transmission development in North America with grid investment expected to nearly double by 2010. Increasing congestion costs in many high demand areas of the country, the growing development of renewable generation located far from load centers, and enhanced regulatory support at the state, regional, and federal levels are driving this growth," said David Gee, President of AES North America. "Independent electric transmission is a natural complement to our existing generation development business. We also see significant synergy and opportunity in working with Trans-Elect's development team as they are proven and respected in the transmission business."

Trans-Elect was formed in 1999 as the first independent transmission company in North America to pursue the development of independently-owned electric transmission with the goal of increasing the reliability of the system and lowering costs to consumers. Since 2002, Trans-Elect has acquired an interest in the AltaLink transmission system in Alberta, Canada, purchased Consumers Energy's Michigan transmission system and secured financing to construct the expansion of the Path 15 transmission line in California. Before being sold to third-parties, these assets totaled 12,600 miles of transmission assets under management.

"Trans-Elect is proud to have pioneered independent electric transmission ownership and new transmission development in this country," said Bob Mitchell, Chief Executive Officer of Trans-Elect Development, LLC, and a former executive at Trans-Elect. "We are excited about this new relationship with AES as they have been a creative force in developing independent generation in the US. Additionally, we believe that AES's development skills, industry relationships, and financing capabilities will enhance our efforts to meet the nation's electricity needs."

Transmission investment in the United States has increased dramatically since the late 1990's from $2.5 billion in 1998 to $5.5 billion in 2005. According to the Edison Electric Institute, transmission investment could reach $8.0 billion per year by 2008 and $10.0 billion or more by 2010.
