CHEYENNE, Wyo. (AP) — A utility proposes to build a wind farm in Wyoming to serve commercial electricity customers.

Rapid City, South Dakota-based Black Hills Energy says the 40-megawatt Corriedale Wind Energy Project would be built west of Cheyenne.

Black Hills Energy outlined plans for the $57 million wind farm in a filing with the Wyoming Public Service Commission on Monday.

The wind farm is part of a program that would enable local commercial utility customers to get up to all of their electricity from renewable sources. The Wyoming Tribune Eagle reports the wind farm would be built by the fall of 2020 if approved.

Black Hills Energy and subsidiaries already operate 89 megawatts of wind-generation facilities serving utility customers in Colorado.
