Nameplate capacity, not generation. Solar has by far the most plants of any fuel but produces less per megawatt installed than nuclear or gas, so its share here is larger than its share of the electricity actually generated — compare with the generation mix →

How the plant directory works

This page counts the power plants in the United States and their generating capacity. The list comes from the U.S. Energy Information Administration (EIA) inventory of operable generators, in its August 2026 release. A plant here is the group of generators sharing an EIA plant code. The inventory includes operating units, units on standby and units out of service, but not units that have been retired or not yet built.

Capacity means nameplate capacity: the output a generator is rated for at full power, in megawatts. It is not how much electricity a plant produced. Each plant is filed under its primary fuel, the fuel with the largest total nameplate capacity among its operating generators, and its whole capacity counts toward that fuel. A gas plant with a small solar array counts as gas, so these shares differ slightly from a unit-by-unit count.

The inventory lists 14,725 plants with 1,411.6 GW of capacity. Natural gas is the largest fuel at 587.4 GW, 41.6% of the total, across 2,011 plants. Solar has the most plants, 7,509, with 184.3 GW of capacity between them. The largest single plant is Grand Coulee in Washington at 6,809 MW. Texas has the most capacity of any state, 204.9 GW across 1,095 plants.

These numbers change as generators are added and retired. New construction follows fuel prices, state and federal policy, demand for power and the cost of equipment. A plant’s primary fuel can also change when units open, close or go out of service. EIA updates the inventory monthly. To see how much electricity each source actually produced, compare this page with the generation mix.

Frequently asked questions

›How many power plants are there in the United States?

14,725 operable power plants, with a combined nameplate capacity of 1,411.6 GW, according to EIA's inventory of operable generators for August 2026. That counts every plant EIA tracks, from multi-gigawatt nuclear stations to sub-megawatt backup generators.

›What is the largest power plant in the United States?

Grand Coulee in Washington, a hydro plant with 6,809 MW of nameplate capacity, in service since March 1941. Vogtle in Georgia is second at 4,658 MW.

›Which fuel accounts for the most US generating capacity?

Natural gas, at 587.4 GW across 2,011 plants — 41.6% of all US capacity. Solar follows at 13.1%, Coal follows at 12.7%, Wind follows at 11.8%. This is capacity rather than generation: solar has far more capacity per unit of output than nuclear does, so the two rankings differ.

›Which state has the most generating capacity?

Texas, with 204.9 GW across 1,095 plants. California is second at 109.6 GW, and Florida third at 81 GW.
