How much power plant capacity does the U.S. have?

Operating utility-scale generators add up to 1,411.5 GW of nameplate capacity as of August 2026. Natural gas is the largest share at 41.2%.

What is the largest power plant in the U.S.?

By nameplate capacity, Grand Coulee in Washington is the largest, at 6.8 GW (hydroelectric).

What is nameplate capacity?

Nameplate capacity is the maximum output a generator is designed for, in megawatts (MW). Plants rarely run at full output all the time. Energy produced over time is measured in megawatt-hours (MWh).
