Snohomish PUD and Ameresco have signed a contract to construct a battery energy storage system (BESS) that will be the largest battery project to date in the Pacific Northwest. The BESS will have a 20-year guaranteed capacity of 25 megawatts and 100 megawatt-hours. Ameresco will be the asset owner while Snohomish PUD will be the exclusive customer of the project. The BESS will provide the PUD with enhanced electrical system reliability and flexibility while reducing exposure to energy price volatility.
“We’re excited to work with Ameresco on making this new battery energy storage project a reality,” stated John Haarlow, Snohomish PUD CEO/General Manager. “Energy storage is a critical component to helping us keep the grid reliable and affordable while also meeting our clean energy goals.”
Construction is currently expected to begin in late 2024, with the system becoming operational in late 2025.
