Behind-the-Meter
Data Center Tracker
Data centers that can’t wait for the grid are building their own power plants. We track each one from its first permit: the data center it serves, its capacity and status, and every turbine, engine and fuel cell inside it.

Every turbine, engine and fuel cell
We track the machines inside every plant: who makes them, which model and how many. They come from air permits, utility filings and the makers’ own documents, and each model links to its ratings and specs.
We currently track 18,127 machines from 19 makers and 49 models.
