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 ...
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 ...
When there is enough flow, power output is limited by plant generating capacity. The maximum power-output curves were calculated based on the average flow rate at the dam site, assuming the water level is 175 m and the plant gross efficiency is 90.15%. The actual power output in 2008 was obtained based on the monthly electricity sent to the grid.
The installed capacity of the Power House is 780 MW consisting of 6 Units of Pelton-type turbines with a power generation capacity of 130 MW each. The regulated waters of Periyar falls through a drop of about 669.2 m (2,196 ft) while generating power in the underground power house. The generated power is given to two sub stations.
The classification of a plant as an SHP or LHP is primarily based on its nameplate capacity, the threshold varies by the country, but in any case a plant with the capacity of 50 MW or more is considered an LHP. [28] As an example, for China, SHP power is below 25 MW, for India - below 15 MW, most of Europe - below 10 MW. [29]
This was the fuel that launched the industrial revolution and continued to grow in use; China, which already has many of the world's most polluted cities, [2] was in 2007 building about two coal-fired power plants every week. [3] [4] Coal's large reserves would make it a popular candidate to meet the energy demand of the global community, short ...
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 ...
