"Alternative energy is a promising sector within the energy industry and will be an important driver in our overall growth strategy. We also will continue to deliver long-term earnings growth from our core power business, by focusing our expansion efforts on markets with a growing demand for power."

In its core power business, AES plans to expand its current base of 40,000 MW worldwide to up to 46,500 MW by 2011. The Company currently has five power plants under construction totaling 1,682 MW in four countries and 20,000 MW of potential new greenfield power plants worldwide in its development pipeline.

In the area of alternative energy, the Company plans to more than triple its wind capacity over the next four years by adding approximately 2,100 MW in new wind generation worldwide by 2011. The Company today has 600 MW of wind generation in operations, one 233 MW power plant under construction and 3,000 MW of wind projects in various stages of development throughout the world.
