Electrical Engineering Fundamentals

Kilowatt-hour (kWh)

Definition

A unit of electrical energy equal to one kilowatt of power sustained for one hour (1 kWh = 1 kW × 1 hr). Energy in kWh represents the total quantity of electricity consumed or produced over time, as opposed to power (kW or MW) which is an instantaneous rate. Wholesale energy markets settle transactions in MWh (megawatt-hours), and retail bills are typically denominated in kWh. One kWh is equivalent to 3.6 megajoules or approximately 3,412 British thermal units (Btu).
