BPA-G0840 is a proposed 600 MW hybrid solar and battery project located in Douglas County, Washington. The project, consisting of 300 MW of solar generation and 300 MW of battery energy storage, is in the Bonneville Power Administration (BPA) interconnection queue, with an entry date of February 7, 2023. The proposed commercial operation date is December 31, 2027.
The interconnection agreement (IA) status for BPA-G0840 is listed as "In Progress (unknown study)". The point of interconnection (POI) is the Chief Joseph-Sickler No 1 500kV line.
