Abstract
A computer and controls system which monitors the application of power or other quantities subject to demand in which increased costs results due to periodic periods of high demand and controls loads on the system so that the cost is minimized while maintaining the desired service. This invention also allows continuous demand monitoring on industrial processes which are necessary for a specific application.
