Several companies that were accused of relatively small breaches of conduct during the energy crisis had their settlements approved by the Federal Energy Regulatory Commission last week. The final move January 22 sealed the agreements, which were filed for approval in fall 2003. Williams will return $45,230 from ?participation in alleged gaming activities.? The city of Redding will send in a check for $6,300. Puget Sound Energy has to return $17,092. San Diego Gas & Electric will hand over $27,000. American Electric Power will return $45,240 it received in payments for congestion relief from the California Independent System Operator. At the same time FERC approved the settlement amounts, it dismissed cases against Southern California Edison and its parent, Edison International, as well as PG&E Corp. and Sierra Pacific. In other FERC orders, Mirant?currently in bankruptcy proceedings?was granted a hearing for its reliability must-run rates for its Potrero, Delta, and Contra Costa plants. Mirant has asked for authorization of rates. Some market stakeholders, including the California Independent System Operator, maintain the generator doesn?t have the data to support its rates.
