The utility's 229MW Wild Horse Wind Project in Kittitas County began commercial operation for PSE customers in late December.

Together with the Hopkins Ridge Wind Project that PSE built in 2005 near Dayton in southeast Washington, Wild Horse makes PSE the largest producer of renewable energy in the Pacific Northwest. Wild Horse's 127 turbines spinning atop Whisky Dick Mountain, east of Ellensburg, are generating enough wind-fueled electricity, on average, to serve 76,000 of the utility's million-plus electric customers in Western Washington and Kittitas County. Wild Horse and the 83-turbine Hopkins Ridge wind farm, combined, can meet the power needs of roughly 125,000 households.
