The availability factor of a power plant is the amount of time that it is able to produce electricity over a certain period, divided by the amount of the time in the period. Occasions where only partial capacity is available may or may not be deducted. Where they are deducted, the metric is titled equivalent availability factor (EAF).
Availability Capacity factor is the ratio of the average output of a facility to its maximum output. It is always less than 100% – either because the facility is not capable of maintaining its maximum output all the time, or because there is sometimes little or no demand for its output, or some combination of the two.
The average capacity factor can also be defined for any class of such installations, and can be used to compare different types of electricity production. The actual energy output during that period and the capacity factor vary greatly depending on a range of factors.
The difference arises when the plant is run at less than full capacity, in which case the capacity factor is less than the availability factor. The availability of a power plant varies greatly depending on the type of fuel, the design of the plant and how the plant is operated.
Capacity factor (CF) implies the relation of the real annual electrical energy generation and electrical energy which could be generated if the PV solar plant would operate with total installed (nominal) power 24 h a day over a year. Capacity factors vary greatly depending on the type of energy sources that are used and the design of the plant.
With a nameplate capacity of 25.7 MW and an actual average annual production of 26.98 GWh/year it has a capacity factor of 12.0%. There are several reasons why a plant would have a capacity factor lower than 100%. These include technical constraints, such as availability of the plant, economic reasons, and availability of the energy resource.

Abstract: Under the background of "dual-carbon" strategy, China is actively constructing a new type of power system mainly based on renewable energy, and large-scale energy storage power capacity allocation is an important part of it. This paper analyzes the differences between the power balance process of conventional and renewable power grids, and proposes a power …
As soon as the total capacity of the nuclear power stations exceeds the base load, their capacity factor will start to go down – unless you have energy storage facilities. The fixed costs of nuclear power stations are so high that keeping their capacity factors high is absolutely critical to their economics, so very few countries have more ...

For renewable energy sources such as solar power, wind power and hydroelectricity, the main reason for reduced capacity factor is generally the availability of the energy source. The plant may be capable of producing electricity, but its "fuel" (wind, sunlight or water) may not be available. A hydroelectric plant''s production may also be affected by requirements to keep the water level from getting too high or low and to provide water for fish downstream. However, solar, wind and hydro…
