Nameplate capacity

Nameplate capacity, also known as the rated capacity, nominal capacity, installed capacity, or maximum effect, is the output of a facility such as a power station, electric generator, a chemical plant, fuel plant, metal refinery, mine, 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).
Power plants with an output consistently near their nameplate capacity have a high capacity factor.
