PORTLAND, Ore. - PPM Energy, Inc. (PPM), ScottishPower's (NYSE: SPI) competitive US energy business, today announced that it will build and own the Mountain View III wind plant in Riverside County, California.

PPM has sold 25 megawatts of wind output to San Diego Gas & Electric under a 15-year contract.

PPM has a 750-megawatt wind supply portfolio, including 162 megawatts from the recently commissioned High Winds Energy Center in northern California. PPM balances its supply portfolio with sales to wholesale customers, placing most of its output in long-term contracts. Major customers include the cities of Seattle, Sacramento, Pasadena and Anaheim as well as investor-owned utilities such as Alliant Energy and Xcel Energy and the federal Bonneville Power Administration.

SeaWest WindPower of San Diego jointly developed the Mountain View III plant with PPM and will construct 34 Vestas 660 kW wind turbines at the site. The turbines will have a generating capacity of 22 megawatts. Construction is expected to be completed by the end of 2003. PPM also will add three megawatts from its existing wind supply portfolio to bring the total wind sale to SDG&E to 25 megawatts.

"California is important to PPM. By marketing the entire output of the High Winds Energy Center in northern California and now building the Mountain View III plant in southern California, PPM is demonstrating our commitment to helping California meet its renewable energy needs from north to south," said Terry Hudgens, PPM's CEO. "We also applaud San Diego Gas & Electric's leadership in bringing sustainable new resources to customers of California investor-owned utilities."

With a portfolio of more than 750 megawatts of wind power currently in operation or under construction, PPM has a goal of bringing 2,000 megawatts of new wind power to market by 2010. PPM also has about 800 megawatts of clean gas resources under its control to give customers a wide range of options for adding environmentally responsible energy to their portfolios. The American Wind Energy Association honored PPM with its "Market Maker of the Year" award for aggressively finding markets for wind power.
