Description

As of December 19, 2022, this project is in the conceptual phase. An engineer has not been selected. A firm timeline for bidding and start of construction has not been determined. Proposed development of a hydroelectric pumped project rate up to 500 megawatts. The Banks Lake Pumped Storage Project would be located in central Washington State and utilize two existing reservoirs--Banks Lake and Lake Roosevelt--to provide a new source of carbon-free capacity and ancillary services to the Pacific Northwest power grid. The project would be located on the west side of Lake Roosevelt just upstream of Grand Coulee Dam and near the Bureau of Reclamation's existing Keys pump-generation plant.
