Silicon Valley Power Adds BESS

Electric municipal utility Silicon Valley Power (SVP) will add a battery energy storage system (BESS) of up to 50 megawatts (MW) to enable additional local area capacity for electrical system reliability and flexibility. 

Ameresco, Inc., a cleantech integrator specializing in energy efficiency and renewable energy, will build the BESS, named Kifer Energy Storage LLC. It will be installed adjacent to the existing Kifer Receiving Station within SVP’s service territory.

The Ameresco-owned asset will start construction in mid-2024, which is also when the 25-year lease and Energy Storage Agreement with the City of Santa Clara will begin. Ameresco and SVP’s goal is for the BESS to be fully operational by the fourth quarter of 2025.

Ameresco will develop, own and operate the BESS, while SVP will supply the charging energy. With a maximum energy capacity of up to 200 megawatt-hours (MWh), the BESS will acquire surplus renewable electricity and provide a clean and reliable resource to integrate renewables, decrease reliance on gas-fired generation and mitigate GHG and criteria air pollutant emissions.

"We are excited to be teaming up with Ameresco to bring this innovative energy storage system to our community,” said Manuel Pineda, Chief Electric Utility Officer of Silicon Valley Power, in a statement. “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."

The batteries at the facility will participate in the California ISO markets and will be able to assist in balancing generation and consumption, reducing congestion and regulating voltage and frequency.
