Every US power plant, unit by unit
What 14,286 plants run on, how big they are, when each generator came online and who operates it, from the federal EIA-860 survey for 2025.

Above the line: the 1,376.6 GW operating at the end of 2025, by the year each generator came online. Below: capacity retired in each year, from EIA’s file of retired generators. No year added more than 2002, most of it natural gas.
From 2016 to 2025, 367.7 GW of today’s capacity came online, 74% of it solar, wind or batteries, while 117.4 GW was retired, 61% of that coal.

Notes on the data
- How big is a US power plant?
Most plants are small; a few hundred giants hold most of the capacity.
- The largest power plants in the US
The top 25 by nameplate capacity, and the biggest site for each fuel.
- How old are US power plants?
The decade each fuel was built in, and the oldest units still working.
- What each state’s power plants run on
Natural gas leads in most states; wind, hydro and coal lead in the rest.
- Nameplate and summer capacity explained
Why a plant’s two capacity numbers differ, technology by technology.
- What came online and what retired, 2016–2025
Ten years of additions and retirements, year by year and fuel by fuel.
- Balancing areas and the plants in them
Who keeps supply and demand matched, and how much capacity each area holds.
