San Jose
Microsoft's San Jose Data Center is a 396,914 square foot facility on 64.5 acres near Alviso, built around 224 small renewable natural gas generators plus diesel backup and an onsite substation, with a maximum electrical draw of about 99 megawatts. The California Energy Commission certified the project's environmental review and granted it a small power plant exemption in 2022, and the city of San Jose approved an addendum covering supporting road and utility work in April 2025. The project is expected to bring about 100 permanent jobs.

San Jose
Prologis was chosen in November 2025 as the preferred developer for 159 acres of city owned land near Highway 237 and Zanker Road, next to the San Jose Santa Clara Regional Wastewater Facility, for a project it calls the Sustainable Technology, Engineering and Manufacturing (STEM) Park. The plan pairs about 1.7 million square feet of data center space across four buildings, totaling roughly 396 megawatts, with another 785,000 square feet of advanced manufacturing space. Prologis estimates the project would create about 6,000 jobs and generate 30 million dollars a year in local tax revenue, though it still needs formal city approval.
