— So to calculate energy output in watt-hours we have to multiply our power rating by the number of hours our plant is running. For example, if we have a 1000MW plant, its maximum energy output in a day would be 24,000MWh (1000MW x 24 hours). However, this assumes that a plant runs continuously at maximum output, which most (if …
