The proposed project BPA-G1040 is an 800 MW hybrid Solar+Battery development project located in Benton County, Washington. Interconnecting to the Bonneville Power Administration (BPA) via the Midway Substation at 230kV, the project entered the BPA interconnection queue on November 21, 2023, with a proposed commercial operation date of December 31, 2030. The interconnection agreement (IA) status is currently listed as "In Progress (unknown study)".
The project consists of a 400 MW solar component and a 400 MW battery energy storage system. The project is currently listed as active in the interconnection queue. The developer is unknown.
