Nameplate capacity

Nameplate capacity, also known as the rated capacity, nominal capacity, installed capacity, maximum effect or Gross Capacity,[1] is the intended full-load sustained output of a facility such as a power station,[2][3] electric generator, a chemical plant,[4] fuel plant, mine,[5] metal refinery,[6] and many others. Nameplate capacity is the theoretical output registered with authorities for classifying the unit. For intermittent power sources, such as wind and solar, nameplate power is the source's output under ideal conditions, such as maximum usable wind or high sun on a clear summer day.

Capacity factor measures the ratio of actual output over an extended period to nameplate capacity. Power plants with an output consistently near their nameplate capacity have a high capacity factor.

For electric power stations, the power output is expressed in Megawatt electrical (MWe). For fuel plants, it is the refinery capacity in barrels per day.[7][8]
