Nameplate capacity

Nameplate capacity, also known as the rated capacity, nominal capacity, installed capacity, maximum effect or Gross Capacity,

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

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

Power stations

Dispatchable power

For dispatchable power, this capacity depends on the internal technical capability of the plant to maintain output for a reasonable amount of time (for example, a day), neither momentarily nor permanently, and without considering external events such as lack of fuel or internal events such as maintenance.[9] Actual output can be different from nameplate capacity for a number of reasons depending on equipment and circumstances.[9][10]

Non-dispatchable power

For

hydroelectric dam water levels, tidal
variations and other outside forces. Equipment failures and maintenance usually contribute less to capacity factor reduction than the innate variation of the power source. In
MWDC or MWAC, to identify the raw DC power or converted AC power output.[citation needed

Generator capacity

power-plant, with power-consuming pump

The term is connected with

electrical generators as these plates describing the model name and manufacturer usually also contain the rated output,[11] but the rated output of a power station to the electrical grid
is invariably less than the generator nameplate capacity, because the components connecting the actual generator to the "grid" also use power. Thus there is a distinction between component capacity and facility capacity.
