Capacity factor
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 the energy it would have produced at full capacity.
Electrical energy is usually measured in
watt-hours, Kilowatt-hours or megawatt-hours in the
electrical industry. Kilowatts or megawatts alone are not units of
energy. They are units of
power. Energy is power multiplied by time. Capacity factors vary greatly depending on the type of
fuel that is used and the design of the plant. The capacity factor should not be confused with the
availability factor.

Capacity factor (gross)
The ratio of the gross electricity generated, for the time considered, to the energy that could have been generated at continuous full-power operation during the same period.
Capacity factor (net)
The ratio of the net electricity generated, for the time considered, to the energy that could have been generated at continuous full-power operation during the same period.

chromatographic parameter that measures the degree of retention — "The capacity factor is a measure of where the peak of interest is located with respect to the void volume, i.e., elution time of the non-retained components".
