What is Generation Capacity? | Department of Energy
Capacity is the amount of electricity a generator can produce when it''s running at full blast. This maximum amount of power is typically measured in megawatts (MW) or kilowatts and helps utilities project just how big of an electricity load a generator can handle. U.S. nuclear generation capacity exceeded more than 9 5 gigawatts in 2021.
