1. A power management system for improving the power utilization of a facility having a plurality of electric power consuming loads, comprising:
- system control means for monitoring the power input to the facility and for developing a first control signal when the input power exceeds a predetermined peak level; and
load control means for monitoring each load of the facility to determine which loads are running and therefore are eligible for shutdown on a prioritized basis, said load control means being responsive to said first control signal and operative to shutdown for predetermined periods of time one or more of the lowest priority eligible loads in the facility as required to prevent the peak power consumption of the facility from exceeding said predetermined peak level.
