Shepherds Flat Wind Farm is a planned wind farm near Arlington, Oregon, United States. Installation of the wind turbines is scheduled to begin in 2010 and the project is expected to be fully built in 2012.[1] Built by Caithness Energy, it will supply electricity to Southern California Edison. The wind farm is projected to be the largest land-based wind farm in the world when it is completed.[2]



Construction on the project is expected to employ 400 people to build 90 miles (140 km) of power lines and 85 miles (137 km) of roads on the 30-square-mile (78 km2) wind farm.[1] The project is located in Eastern Oregon in both Morrow and Gilliam counties, with the majority of the turbines to be in Gilliam County.[3] Oregon provided tax incentives to the developer to help land the facility,[3][4] but the project is expected to provide Gilliam County with about $5 million annually in taxes and fees when it is operating.[3] Shepherds Flat is entirely on private property approximately 5 miles (8.0 km) southeast of the city of Arlington between Oregon Route 19 and Oregon Route 74.[5]

Plans for the project first came in 2002 for a 105 megawatt project, with the plan changed to larger project in 2004.[6] The project was then submitted to the state in 2006 with plans to have the first phase online in 2008.[7] Early plans called for 303 turbines and a generating capacity of 909 megawatts.[2] At the time, it would have doubled the capacity for wind-generated power in Oregon.[8] The farm is divided into several sections, with the Willow Creek Wind Farm between two of the larger segments.[9]

Approved in 2008 by state regulators,[5] groundbreaking came in 2009.[3] The project design now includes 338 turbines built by General Electric, each with a capacity to produce 2.5 megawatts.[1] These turbines and a ten-year service contract cost a total of $1.4 billion, the largest expense on the estimated $2 billion project.[1] Generating capacity will be 845 megawatts, producing an estimated 2 billion KWh each year, enough to provide electricity to 235,000 homes.[1] Once operational, the facility will have about 35 permanent employees.[1] It is anticipated to be the largest wind farm on land at the time it is completed, with larger wind farms planned elsewhere set to surpass Shepherds Flat in later years.[5][2] The wind farm is estimated to have an economic impact of $16 million annually for Oregon.[10]
