Ameresco to build 200MWh BESS for Silicon Valley Power

Cleantech integrator Ameresco is to construct a 50MW / 200MWh battery energy storage system (BESS) for Silicon Valley Power (SVP).

The BESS, named Kifer Energy Storage LLC, will be installed adjacent to the existing Kifer receiving Sstation within SVP’s service territory.

The Ameresco owned asset, which is scheduled to begin construction in mid-2024, will mark the beginning of a 25-year lease and energy storage agreement with the City of Santa Clara. 

Ameresco will develop, own, and operate the BESS, while SVP will supply the charging energy. 

Additionally, the batteries at the facility will participate in the California ISO markets, assist in balancing generation and consumption, reducing congestion and regulating voltage and frequency. Ameresco and SVP aim for the BESS to be fully operational by the fourth quarter of 2025.

“We’re thrilled to announce our partnership with Silicon Valley Power to bring this state-of-the-art battery energy storage system to life,” said Britta MacIntosh, Ameresco executive vice president and general manager, west region. “This asset installation really is a game-changer, not just for enhancing SVP's system reliability, but also for advancing and integrating the renewable energy sources of the future.”

Manuel Pineda, chief electric utility officer at Silicon Valley Power, said: “With the installation of this new battery storage system, we are committed to providing reliable and flexible power solutions for our customers embracing renewable energy integration. This project is perfectly aligned with our mission to deliver affordable, sustainable, and environmentally friendly energy options. Together, we hope to help lead the way towards a greener Silicon Valley."
