Vantage CA3 data center (2590 Walsh Avenue)
Also called: CA3 Backup Generating Facility, 21-SPPE-01
Vantage built a large data center on Walsh Avenue in Santa Clara. Its 44 diesel backup generators can make up to 96 megawatts, so the state Energy Commission reviewed it in 2022. A tracker lists it as running since 2025, using about 83 megawatts.
Where things stand: Trackers list it as operating since 2025.
🕒 Latest update (Aug 10, 2022): The California Energy Commission voted to exempt the project's 96 MW of backup generators from a state power plant license, leaving approval to the city.
