Iberdrola Renewables announced a 20-year agreement to sell SDG&E 100 MW from the Manzana project in February 2012. The announcement described a 189 MW wind farm under construction near Rosamond, California. Contracted MW express power capacity, rather than annual energy in MWh.
The developer’s 100 MW, 20-year SDG&E announcement explicitly identifies Manzana near Rosamond, California. Blue Creek is a separate Avangrid wind farm in Ohio.
