March 21, 2003 March 21, 2003 California's Electricity Oversight Board (EOB) today held hearings on steps being considered by the California Independent System Operator (Cal-ISO) to redesign the state's electricity markets. In response, SCE offered the following comment. ROSEMEAD, Calif., March 21, 2003 - In general, we support market changes proposed by Cal-ISO, including the use of Locational Marginal Pricing. However, we believe it is important that each change be thoroughly studied, even if that requires delaying the current implementation schedule. # # # An Edison International company, Southern California Edison is one of the nation's largest electric utilities, serving a population of more than 12 million via 4.5 million customer accounts in a 50,000-square-mile service area within central, coastal and Southern California.
