CA Attorney General Sues Reliant and Mirant

LCG, April 16, 2002--Yesterday California Attorney General Bill Lockyer filed yet another suit against power companies; he alleges that Reliant Energy and Mirant Corp. illegally owned power assets.

Lockyer asserted that power plants held by the two companies enabled them to have monopolistic control over the power market. He requested that a San Francisco federal court order the sale of some of the companies' plants.

The companies both deny the charges and add that the case may have been inspired by the upcoming election in November.

Lockyer says that the companies bought plants in order to raise prices. He also insists that Mirant's plants provide 44 percent of electricity in northern California and Reliant's yield 28 percent of southern California's electricity.

Meanwhile, Mirant spokesman Patrick Dorinson says that his corporation only controls six percent of California energy capacity, and both he and Reliant spokesman Richard Wheatley deny any possibility of infringing on antitrust laws.

Lockyer has filed several other electricity-related suits recently, including suing Mirant and other companies for unreasonably high prices during the energy crisis of 2000 and 2001.
