The measure of the capacity of a battery storage system uses two terms: megawatt-hour (MWh) and megawatt (MW). A megawatt is a simple measure of power - a million watts or 1,000 kilowatts. A megawatt-hour is a unit of energy - one megawatt, for an hour, or the same as 1,000 kilowatt-hours (kWh). You may be familiar with kWh as that''s …
