The proposed project BPA-G0684 is a 705 MW hybrid Solar+Battery project located in Benton County, Washington. The project, which consists of 470 MW of solar capacity and 235 MW of battery storage, is interconnected to the Bonneville Power Administration (BPA) via the Wautoma 500 kV Substation.
The project is currently active in the BPA interconnection queue, having entered on July 23, 2021, with a proposed commercial operation date of October 1, 2024. The interconnection agreement (IA) status is listed as "In Progress (unknown study)". The project has appeared in recent news.
