The Dworshak Fourth Unit is a proposed 300 MW hydroelectric generation project located in Clearwater County, Idaho. The project, identified as BPA-G0492 in the Bonneville Power Administration (BPA) interconnection queue, was entered into the queue on August 2, 2013, with a proposed commercial operation date of July 1, 2019. Its interconnection status is currently in the Facility Study phase.
The proposed project is linked to the existing Dworshak hydroelectric generating facility (EIA ID 840). Recent news coverage has discussed the development.
