During a given period, the amount of electricity actually produced by a power station expressed as a function of the amount that it would produce if it operated continuously at full power in the same3 period. For a nuclear station operating on base load, this is very close to the availability.

The ratio of the average load on (or power output of) a generating unit or system to the capacity rating of the unit or system over a specified period of time.

(1) The ratio of the average load on a generating resource to its capacity rating during a specified period of time. (2) The amount of energy that the system produces at a particular site as a percentage of the total amount that it would produce if it operated at rated capacity during the entire year.

The ratio of total energy generated by a plant for a specified period of time to the maximum possible energy it could have generated if operated at the maximum capacity rating for the same period, expressed as a percent.

The ratio of the average power load of an electric power plant to its rated capacity

The ratio of the average amount of gas transported on a pipeline to the rated capacity of the system. For example, if a pipeline transports 80 MMcf/d and has a rated capacity of 100 MMcf/d, then the capacity factor is 80 percent.

An electric utility's annual capacity factor is defined as the annual kilowatt-hour sales divided by the product of the total hours in a year and the rated capacity of the utility in kilowatts.

Ratio of average generation to the capacity rating of an electric generating unit for a specific period (expressed in percentage).

the ratio of the capacity of an operation to the practical capacity.

A measure of the degree to which the capacity of a generating unit is being used during a specified period of time. Expressed as a ratio of the electric energy produced during the specified period to the electric energy the unit could have produced if it operated at full capacity during the entire period.

The actual output of a generation plant over a period compared to the expected maximum output from the plant in that period based on 100% availability at the manufacturer's operating specifications.

The amount of energy a facility generates in one year divided by the total amount it could generate if it ran at full capacity. A capacity factor of one implies that the system ran at full capacity the entire year; a typical wind farm will operate at 0.25 capacity factor, or 25%.

The ratio of the electrical energy produced by a generating unit relative to the electrical energy that could have been produced at continuous full power operation during the same period of time. The Capacity Factor for wind energy in the UK is typically between 20% and 40%.

The ratio of the energy that a power-generating system produces to the energy that would be produced if it were operated at full capacity throughout a given period, usually one year.

The ratio of the electricity generated by a power plant compared to the electricity that could have been produced during a specific period if the plant had operated continuously at full power.

The ratio of the electrical energy produced by a generating unit for the period of time considered to the electrical energy that could have been produced at continuous full-power operation during the same period.

The ratio of the actual sales during any specified period to the maximum amount of sales the system is capable of delivering during that time.

The ratio of the actual sales, production or use during a defined period of time to the maximum amount of sales, production, or use the system is capable of handling during that period.

The capacity factor of a power plant is the ratio of the actual output of a power plant over a period of time and its output if it had operated a full capacity of that time period. This is calculated by totaling the energy the plant produced and dividing it by how the energy it would have produced at full capacity. Electrical energy is usually measured in watt-hours.
