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.

What you can do in California

You don’t have to accept it — and you don’t have to be anti-growth to demand accountability. File a public records request to learn a project’s power draw, water use, and abatement terms, speak up at a city-council meeting, and see the full playbook on our Take Action page.
