Nameplate capacity

intended full-load sustained output of a facility

Nameplate capacity, also known as the rated capacity, nominal capacity, installed capacity, or maximum effect, is the intended full-load sustained output of a facility such as a power station,[1][2] electric generator, a chemical plant,[3] fuel plant,[4][5][6] metal refinery,[7] mine,[8] and many others. Nameplate capacity is the number registered with government authorities for classifying the power output of a power station; it is usually written in megawatts (MW).[9]

Power plants with an output consistently near their nameplate capacity have a high capacity factor.
