Concept

The hot reserve or reserve capacity of a power plant is given by:

Hot reserve = Plant capacity - Demand capacity

Calculation

Given, Plant capacity =  200 MVA

Demand capacity = 120 MVA

Hot reserve = 200 - 120

Hot reserve = 80 MVA

Additional Information The plant capacity factor is given by:

\(Plant \space capacity \space factor={Average \space demand\over Plant \space capacity}\)
