terawatt-hour
Billion kilowatt-hours
A terawatt-hour is a unit of energy equal to one trillion watt-hours, used to measure large-scale electricity production or consumption.
National power grids and major utilities report output in terawatt-hours: The country consumed 4,000 terawatt-hours of electricity last year.
Abbreviated TWh.
