Siemens Energy has recently finalized its contract with Pattern Energy for the Ocotillo Wind power project in Southern California. The wind power plant is currently under construction and most of the project will be placed into commercial operation in 2012, with a portion going online in the first half of 2013. The scope of supply encompasses delivery, technical field assistance and commissioning of the 112 SWT-2.3-108 wind turbines, including a two-year service and maintenance contract. The majority of the wind turbines for this project are manufactured in the U.S. Additionally, the 115-megawatt (MW) El Arrayán wind power plant in Chile will utilize nacelles and hubs from the Hutchinson, Kansas, facility and blades from the Fort Madison, Iowa, plant. Construction is scheduled to begin in 2013. "We are very pleased to once again partner with Pattern Energy on another of its wind projects. Our U.S. factories will supply the blades and the majority of the nacelles and hubs for the Ocotillo Wind project, and we will also export components to Chile. Siemens has invested more than $100 million in our factories here in the U.S. over the last five years and we remain committed to providing our wind turbines to the U.S. industry as well as exporting them to markets across the Americas,” stated Mark Albenze, CEO of Siemens Energy’s Wind Power Americas business. "Our partnership with Siemens has been a strong source of jobs in the United States," said Mike Garland, CEO of Pattern Energy. "Our Ocotillo Wind project in California is using Siemens wind turbines with towers, blades and nacelles that are made in America. Pattern and Siemens also successfully worked together to supply our El Arrayán project with American-made Siemens turbines that will be exported to Chile, which will continue to support American jobs." Ocotillo Wind marks the 10th project completed, in development or under contract with Pattern Energy, totaling more than 800 wind turbine units capable of producing clean energy for more than 500,000 average homes. At the end of October 2012, Siemens completed commissioning of 44 SWT-2.3-108 units for Pattern Energy’s Santa Isabel Wind project in Puerto Rico, which is the first commercial-scale wind power project in Puerto Rico and the largest in the Caribbean. The wind power plant will help the island achieve the current administration’s aggressive plan to diversify Puerto Rico’s energy sources.
