PacifiCorp has become the sole owner of the 41.4-MW Foote Creek I wind project in Carbon County, Wyo., and will begin the process of repowering the facility, the company said.
Foote Creek I, which began operating in 1999, was PacifiCorp's first wind energy facility and the first utility-scale wind farm in Wyoming, the company said in an Aug. 12 news release. The Eugene Water & Electric Board, owned by the city of Eugene, Ore., held a roughly 21% interest in the wind farm, and its output was sold to the Bonneville Power Administration under a power purchase agreement that expired in July.
Repowering the facility will involve replacing 68 units of 600-kW generators with 13 modern turbines and installing new foundations, energy collector circuits, switchgears and controls. PacifiCorp said the repowering is in addition to a broader multibillion-dollar effort to add more than 1,100 MW of new wind energy capacity, repower other wind energy facilities and build a 140-mile segment of a 500-kV transmission project.
The process will boost the project's output by 60% and will allow the facility to generate enough power for 19,500 residential homes. Repowering the project in 2020 will requalify it for federal production tax credits.
PacifiCorp is a subsidiary of Berkshire Hathaway Energy.
