Rosemead, California [RenewableEnergyAccess.com] Southern California Edison (SCE) signed a wind energy contract that will provide the utility’s customers with 1500 megawatts (MW) of renewable, emission-free power to be generated by new projects to be built in the Tehachapi area of California.The agreement with Alta Windpower Development LLC, a subsidiary of Allco Financial Group Inc. of Australia, more than doubles SCE’s wind energy portfolio and envisions more than 50 square miles of wind parks in the Tehachapi region — triple the size of any existing U.S. wind farm. Oak Creek Energy Systems Inc. of Mojave, Calif., is a partner with Allco in the development, construction, and operations of the projects. “We are pleased our long-term commitment to the Tehachapi area is helping to produce such a ground-breaking project,” said Hal Romanowitz, president of Oak Creek Energy Systems. These agreements bring to 1,889 MW the amount of environmentally sensitive power resulting from SCE’s 2005 competitive renewable energy solicitation — the equivalent of two traditional power plants and enough generation to serve one million average homes. The success of this large wind project depends on SCE receiving authorization from the CPUC and other regulatory agencies to construct a series of new and upgraded high-voltage transmission lines that would deliver electricity from potential new wind farms in the Tehachapi area. When completed, this renewable transmission project would be capable of delivering 4,500 MW of electricity, enough energy to supply almost three million homes.
