Ninety-Five Percent of AES Gener’s Capacity Serving the Chilean Market is Operational Following Earthquakes

The AES Corporation (NYSE: AES) today provided an update on its operations in Chile following the earthquake on February 27, 2010 and subsequent aftershocks. AES Gener, a 71 percent owned subsidiary of AES Corporation, continues to meet 100 percent of its current energy obligations in Chile.

AES Gener has inspected all facilities for damage from the earthquake and repairs have been largely completed. As of March 22, 95 percent, or 2,975 MW of 3,129 MW, of AES Gener’s total capacity serving the Chilean market is operational. At any given time, certain facilities are not operational due to dispatch priorities or regularly scheduled maintenance. The 100 MW Renca plant will continue to undergo repairs and is one of the facilities that would not have otherwise been operational. In addition, the 55 MW Laguna Verde facility, which was not affected by the earthquake, is undergoing scheduled maintenance. AES Gener’s construction sites, the 518 MW Angamos, 152 MW Guacolda 4 and 270 MW Campiche facilities, were not affected by the earthquake or subsequent aftershocks.

AES Gener has a total of 3,129 MW of capacity to serve the Chilean market and an additional 1,000 MW of hydro capacity in Colombia. Of the total 3,129 MW of capacity to serve Chile, 920 MW operate in the northern interconnected grid (SING) which was not affected by the earthquake. This number includes the 643 MW Termoandes facility, which is located in Argentina and provides a portion of its power to the Chilean market. AES Gener operates 2,209 MW in the central interconnect grid (SIC), mainly in the central portion of the country near Santiago. AES and AES Gener will provide more information on the changes in demand level when the companies disclose their first quarter 2010 earnings.
