The city of Lancaster signed a 20-year agreement with sPower for the renewable energy company to provide it with 10 megawatts of solar power annually. sPower, based in Salt Lake City, will generate the electricity at the Western Antelope Dry Ranch facility it plans to construct at 105th Street West and Avenue J in Lancaster. The facility, which will use 41,000 photovoltaic modules, is expected to be operating by the end of next year. Lancaster will make the power available to residents and businesses through the Lancaster Choice Energy program. In that program, the city procures the power and has it distributed by Southern California Edison. “Lancaster has set some very aggressive renewable energy goals, and the best way our city will achieve them is through long-term partnerships with innovative leaders such as sPower,” Mayor R. Rex Parris said in a prepared statement sPower operates alternative energy projects in 10 states and has others in development in 20 states. It has other facilities within the Antelope Valley. When fully operational, the Western Antelope Dry Ranch facility will generate enough renewable energy to power more than 1,800 homes in the city each year.
