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.
Certain onshore wind farms can reach capacity factors of over 60%, for example the 44 MW Eolo plant in Nicaragua had a net generation of 232.132 GWh in 2015, equivalent to a capacity factor of 60.2%, [7] while United States annual capacity factors from 2013 through 2016 range from 32.2% to 34.7%.
In the context of domestic PV installations, the kilowatt (symbol kW) is the most common unit for nominal power, for example P peak = 1 kW. Colloquial English sometimes conflates the quantity power and its unit by using the non-standard label watt-peak (symbol W p), possibly prefixed as in kilowatt-peak (kW p), megawatt-peak (MW p), etc.
All the SI prefixes are commonly applied to the watt-hour: a kilowatt-hour is 1,000 Wh (kWh); a megawatt-hour is 1 million Wh (MWh); a milliwatt-hour is 1/1,000 Wh (mWh) and so on. The kilowatt-hour is commonly used by electrical energy providers for purposes of billing, since the monthly energy consumption of a typical residential customer ...
The Lieberose Photovoltaic Park – one of the largest in Germany – had a nameplate capacity at opening of 52.79 megawatt and cost some €160 million to build [37] [38] or €3031 per kW. With a yearly output of some 52 GWh (equivalent to just over 5.9 MW) it has a capacity factor just over 11%.
The assumption of the capacity factor has a significant impact on the calculation of LCOE as it determines the actual amount of energy produced by specific installed power. Formulas that output cost per unit of energy ($/MWh) already account for the capacity factor, while formulas that output cost per unit of power ($/MW) do not. [12]
Where 'Wc' is wheeling charge per unit. 'Pw' is the power in MW. The fee associated with wheeling is referred to as a "wheeling charge." This is an amount computed as $/MWh that a transmission owner recovers for the use of its system. If the resource must cross multiple [transmission owner]s, it may be charged a wheeling charge for each one.
In 2022, UK capacity grew by 800 MWh, ending at 2.4 GW / 2.6 GWh. [93] Europe added 1.9 GW, with several more projects planned. [94] In 2020, China added 1,557 MW to its battery storage capacity, while storage facilities for photovoltaics projects accounting for 27% of the capacity, [95] to the total 3,269 MW of electrochemical energy storage ...
