San Diego Gas & Electric (SDG&E) today announced that it has entered into two, long-term contracts to purchase 300 megawatts (MW) of renewable energy for its rapidly expanding portfolio of emissions free power. The first of the new agreements is a 20-year contract to purchase 100 MW from Manzana Wind LLC, a 189 MW wind power facility currently under construction in the wind-rich Tehachapi region near Rosamond, Calif. Manzana Wind LLC, is a subsidiary of Iberdrola Renewables, Inc. When completed in late 2012, the project will be comprised of 126, 1.5 MW wind turbines spread across 4,600 acres. The project represents a reduction in greenhouse gas emissions comparable to removing more than 21,500 cars off of California's roads for one year.
