Peak Load Shaving

Peak Load Shaving refers to operating certain generators specifically to address peak demands in the load cycle of a utility.   The load cycle tends to peak in the mornings and falls during the noon.  It again rises in the evening and the night.

Managing these peaks in the load cycle is an important function of distribution systems. Peak Load Shaving, as this process is known, is done by starting certain power sources specifically to offset this peak demand.  These are usually sources with higher generating costs like diesel generator sets.  These power sources are run only during periods of peak loads or in times of emergency.

Another method of peak load shaving is by providing incentives to customers to reduce consumption during times of peak demands.  This levels the load cycle curve and enables optimum loading of power sources.
