Puget Sound Energy Starts Construction on 142-MW Appaloosa Solar Project in Washington
LCG, September 4, 2025--Puget Sound Energy (PSE) announced yesterday that phased construction has commenced on its 142-MW Appaloosa Solar Project, a utility-scale solar facility underway in southeastern Washington. The project is being built by Qcells EPC, who will serve as the module manufacturer and the engineering, procurement, and construction (EPC) solution provider. Construction is scheduled through 2026, and commercial operation is expected at the end of next year.
The Appaloosa Solar Project will be partially co-located within the existing PSE Lower Snake River Wind Facility footprint in Garfield County, and the project will leverage existing transmission rights and infrastructure. This strategic approach is intended to minimize local impacts and project costs.
PSE's Senior Vice President of Energy Resources stated, "We’re excited to see construction underway to bring clean, reliable utility-scale solar energy to our customers, especially during peak summer months when cooling demand is high. This project demonstrates our commitment to a lower carbon future and advances our efforts to meet Washington state’s ambitious clean energy goals."
Once completed, the Appaloosa Solar Project is expected to contribute 4 percent towards PSE’s 2030 clean energy targets and help meet peak demand during the summer. PSE's targets result from the State of Washington's Clean Energy Transformation Act (CETA) legislation that was signed into law on May 7, 2019. The underlying, fundamental goal of CETA is to provide 100 percent clean electricity by 2045. CETA commits the State to eliminate coal-fired electricity by 2025, achieve a greenhouse gas-neutral electricity supply by 2030, and provide 100 percent clean electricity by 2045.
Since the passage of CETA, PSE states that it has added more than 6,000 MW of renewable energy resources to its generation portfolio, and approximately 2,033 MW of that generation comes from new resources from 11 projects built to serve the energy needs of PSE's customers.
