The Federal Energy Regulatory Commission approved settlements stemming from last year?s ?show cause? order in which regulators called on companies to prove they did not help manipulate California?s energy markets. Coral Power agreed to the biggest settlement in the most recent round?$7.79 million?followed by Sempra with $7.24 million. Dynegy?s settlement is for $3 million, with the city of Glendale at $25,000 and the Northern California Power Agency at $22,400. Regulators have yet to finalize settlements for Duke, Mirant, and the Modesto Irrigation District, among others.
