The U.S. Energy Information Administration publishes data on electricity generation from utility-scale and small-scale systems. Utility-scale systems include power plants that have at least 1 megawatt (MW) of electric generation capacity. Small-scale systems have less than 1 MW (1,000 kilowatts) of electric generation capacity.
