Block 5 of Irsching Power Station in Southern Germany uses natural gas as fuel in a combined cycle converting 1750 megawatts of thermal energy to 847 net MW of usable electricity. It cost €450 million to build. [34] This works out to some €531 per kW of capacity. However, due to the uneconomical prospect of operating it as a peaking power ...
The power generated by a power station is measured in multiples of the watt, typically megawatts (10 6 watts) or gigawatts (10 9 watts). Power stations vary greatly in capacity depending on the type of power plant and on historical, geographical and economic factors.
A kilowatt is a unit of power (rate of flow of energy per unit of time). A kilowatt-hour is a unit of energy. Kilowatt per hour would be a rate of change of power flow with time. Work is the amount of energy transferred to a system; power is the rate of delivery of energy. Energy is measured in joules, or watt-seconds. Power is measured in ...
If a plant is only needed during the day, for example, even if it operates at full power output from 8 am to 8 pm every day (12 hours) all year long, it would only have a 50% capacity factor. Due to low capacity factors, electricity from peaking power plants is relatively expensive because the limited generation has to cover the plant fixed costs.
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.
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]
