July 01, 2005 July 1, 2005 ROSEMEAD, Calif., July 1, 2005—For the second time this year, and the eighth time in three years, Southern California Edison (SCE) today issued a competitive Request for Offers (RFO) for new power contracts with independent generators and marketers. The RFO seeks agreements of up to 56 months in duration that will enhance the electricity supply certainty for the 13 million southern Californians the utility serves. Contracts being sought include dispatchable unit-contingent tolling agreements, non-dispatchable qualifying facilities resources, unit dispatch call options, and daily call options from existing or newly constructed resources. RFO documents are publicly available at www.sce.com/allsourceRFO. “We believe an open, fair, and transparent solicitation for power from independent suppliers is one of the most effective ways to complement our existing power portfolio and assure future service reliability for our customers,” said Pedro Pizarro, SCE’s senior vice president of power procurement. Because SCE functions in a competitive market, the utility does not make public the amount of power sought in a competitive solicitation such as this, nor does it reveal pricing information. On June 30, 2005, the California Public Utilities Commission approved six new long-term renewable power contracts resulting from SCE’s most recent renewable RFO. The contracts will add between 141 megawatts and 427 megawatts of environmentally friendly power generation to SCE’s nation-leading portfolio of renewable power. The utility anticipates launching yet another renewable solicitation later this summer. # # # An Edison International (NYSE:EIX) company, Southern California Edison is one of the nation’s largest electric utilities, serving a population of more than 13 million via 4.6 million customer accounts in a 50,000-square-mile service area within central, coastal and Southern California.
