2023 Appaloosa Solar

The Appaloosa Solar Project consists of 300 MW of alternating current (AC) solar photovoltaic arrays with a battery storage facility capable of storing up to 150 MW of energy. The solar panel array system will be interconnected with underground AC electrical lines to a project substation. A new above ground transmission line approximately 2.5 miles long will interconnect to Puget Sound Energy’s (PSE) Phalen Gulch 230 kilovolt (kV) substation. The project will require approximately 27 miles of new and improved roads for project construction and maintenance.
