The three large wind farms we own and operate, including Wild Horse, Lower Snake River and Hopkins Ridge, generate enough power, on average, to serve 165,000 homes annually. In some cases, PSE sells any the excess green-energy generated by our wind facilities to other entities across the nation. The revenue from these sales helps to reduce our customers’ power costs and allows other utilities to take advantage of the benefits of renewable energy.
