First, we have to convert power into energy. Energy is a measure of power output over time (energy = power x time). So to calculate energy output in watthours 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 ...
