Pattern Energy’s Ocotillo wind project in Southern California began commercial operation, transmitting energy to the Sunrise Powerlink, a newly constructed 117-mile 500-kv transmission line connecting San Diego and the Imperial Valley. The 265-MW Ocotillo project in Imperial Valley has 94 turbines now operational. An additional 18 turbines are expected to be installed in the spring of 2013. San Diego Gas & Electric (SDG&E) will buy the output under a 20-year agreement.
