Data Centers in California
At least 114 data centers have been tracked across California — the 4th state by data-center buildout in the country by capacity.
Need this state’s camera data for your work?
We provide free custom extracts of everything we track: camera locations, brands, operators, dates, agencies, council agendas, and news coverage, for researchers, journalists, students, and advocates. Tell us the geography, time window, and format you need, and we’ll pull it for you. No charge, no strings.
Every one of those 114 data centers draws power and water from the same grid you rely on — reshaping where California rates, land use, and water go, whether or not anyone put it to a vote. Here’s what that means, and what you can do about it.
Statewide, an industry analysis counts about 320 operational and 36 planned or under‑construction data centers in California, plus an estimated $4 million in projected 10‑year tax revenue — the map below shows the 114 we’ve pinned so far, so help us map the rest. Statewide totals: American Edge Project & TECNA, Dec 2025.

What these facilities actually do
Hyperscale data centers aren’t ordinary warehouses. Each one draws megawatts of power and millions of gallons of water, and locks in decades of tax abatements — deals routinely approved with little public scrutiny. Across California, that’s 114 facilities quietly reshaping the grid, water table, and tax base. See how the buildout works and where the power and water go.
How California compares
California ranks #4 of 52 states and territories by tracked data-center capacity — among the biggest buildouts in the nation. Nationwide, we have tracked over 2,000 megawatts and counting. Nearby by camera count: Ohio (90), Oregon (133), Texas (220), Washington (72).
