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.
Nominal power or 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.
Nominal power (or peak power) is the nameplate capacity of photovoltaic (PV) devices, such as solar cells, modules and systems. It is determined by measuring the electric current and voltage in a circuit , while varying the resistance under precisely defined conditions.
For a wind farm, the capacity factor is determined by the availability of wind, the swept area of the turbine and the size of the generator. Transmission line capacity and electricity demand also affect the capacity factor. Typical capacity factors of current wind farms are between 25 and 45%. [12]
The complex was then developed into the largest geothermal field in the world, with a nameplate capacity of 1,517 MW and an annual generation of 6,516 GWh in 2018. [ 2 ] [ 3 ] Geothermal power plants/complexes
The curve represents a boundary of all operating points in the MW/MVAr plane; it is typically drawn with the real power on the horizontal axis, and, for the synchronous generator, resembles a letter D in shape, thus another name for the same curve, D-curve. In some sources the axes are switched, and the curve gets a dome-shaped appearance.

The capacity credit can be much lower than the capacity factor (CF): in a not very probable scenario, if the riskiest time for the power system is after sunset, the capacity credit for solar power without coupled energy storage is zero regardless of its CF [3] (under this scenario all existing conventional power plants would have to be retained after the solar installation is added).
