Abstract
A system, method, and apparatus are disclosed for managing utility consumption. An embodiment is disclosed for reducing peak demand for a utility by staggering requests for that utility. Another embodiment is disclosed in which sensors monitor utility consumption throughout a facility. Those items of equipment not in active use, but still drawing utility resources, are shut down after a predetermined interval. Another embodiment is disclosed in which storage and conversion technologies are used to offset peak demand and the associated peak demand costs.
