The proposed Avista-110 development project is a 560 MW hybrid Solar, Wind, and Battery project located in Garfield County, Washington. Interconnecting to the Avista Utilities grid, the project entered the interconnection queue on January 7, 2021, with a proposed commercial operation date of December 1, 2025. The point of interconnection is listed as DryCreek 230 kV or Walla Walla to Dry Creek 230 kV.
The project consists of 100 MW of solar generation, 275 MW of wind generation, and a 185 MW battery energy storage system. The project is currently listed as active in the interconnection queue.
