Capacity credit (CC, also capacity valueor de-rating factor ) is the fraction of the installed capacity of a power plant which can be relied upon at a given time (typically during system stress),frequently expressed as a percentage of the nameplate capacity. A conventional (dispatchable) power plant can typically.
There are a few similar definitions of the capacity credit:• effective load carrying capability (ELCC) defines the capacity value as the extra load that can be added to the system once the plant is added.
The capacity credit can be much lower than the(CF): in a not very probable scenario, if the riskiest time for the power system is.
