The Stateline Wind Farm is a wind farm located on Vansycle Ridge, which receives 16 to 18 mph (26 – 29 km/h) average wind speeds from the Columbia Gorge, on the border between Washington and Oregon in the United States. With 186 turbines currently operating in both states and 279 more approved for construction, it is the largest wind project in the Northwestern United States and will be the largest in the world.
