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 ...
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).
A plant can also have its output curtailed or intentionally left idle because the electricity is not needed or because the price of electricity is too low to make production economical. This accounts for most of the unused capacity of peaking power plants and load following power plants. Peaking plants may operate for only a few hours per year ...
Declared net capacity (DNC) is a measure of the contribution that a power station makes to the overall capacity of a distribution grid. It is measured in megawatts (MW), or in megawatts electrical for a thermal power station. DNC is sometimes expanded as developed net capacity in British English; The two expansions have exactly the same meaning.
In 2021, the worldwide installed capacity of power plants increased by 347 GW. Solar and wind power plant capacities rose by 80% in one year. [27] As of 2022, the largest photovoltaic (PV) power plants in the world are led by Bhadla Solar Park in India, rated at 2245 MW. Solar thermal power stations in the U.S. have the following output:
This article lists the largest power stations in the world, the ten overall and the five of each type, in terms of installed electrical capacity. Non-renewable power stations are those that run on coal , fuel oils , nuclear fuel , natural gas , oil shale and peat , while renewable power stations run on fuel sources such as biomass , geothermal ...
where "capacity" is the "nameplate capacity" or the maximum allowed output of the plant, "capacity factor" or "load factor" is a measure of the amount of power that a plant produces compared with the amount it would produce if operated at its rated capacity nonstop, heat rate is thermal energy in/electrical energy out, emission intensity (also ...
Most electric power plants use some of the electricity they produce to operate the power plant. Net generation excludes the electricity used for the operation of the power plant. Capacity—the maximum level of electric power (electricity) that a power plant can supply at a specific point in time under certain conditions. [1]
