See which data centers build their own power plants, and whose turbines are inside.
The power plants data centers build for themselves, behind the meter: every gas turbine, engine and fuel cell by maker, model and count, with its capacity, its status and the permit or filing that names it. Built for the sales teams of equipment makers, and for the developers, contractors and lenders around these plants.

Counts from the latest weekly research run. Project files, owners, builders and trades are inside the Ultra plan.
What you get
Every unit, by maker and model
The turbines, engines and fuel cells at each plant, counted from the air permit, filing or announcement that names them, with its words quoted.
Who is winning the orders
Megawatts by maker, split into operating, under construction, permitted and announced, so you see each maker's share and where it is growing.
Tied to the data center
Each plant is matched to the tracked project it powers, so the owner, the builders and the rest of the project file are one click away.
How it works
- 1Open on-site power.
- 2Read capacity by maker, then the plants and their units.
- 3Open a plant's permit or filing, or the project file of the data center it powers.
Who uses it
Questions about On-site power tracker
Where do the unit counts come from?
Air permits and permit applications, regulator filings, company announcements and trade press, searched every week. A count is kept only when its document states the number and names the model or the maker, and the quote is shown with a link to the document. Where two documents disagree, a permit or filing wins over the press, and the other count is shown too.
How is the capacity worked out?
From the megawatts the document gives for each unit. When it gives none, from the maker's own published rating for that model, and the page says which. Backup diesel generators are left out: only the machines that make the plant's power count.
