Abstract

Modular consumption management systems provide benefits of adaptability, customization, and progressive investment to electrical utility customers, particularly those with loads and electrical systems capable of curtailment and mitigation. Providing modules based on measurements made and consumption patterns detected in load profiles of individual loads and the site as a whole is described. Control and mitigation capabilities and methods are described in conjunction with identifying correlative modules that will best serve the needs of the site being monitored by a measurement module. Combined measurement and control modules or control and mitigation modules are also described, as well as interchangeable modules that can be put in place when excess consumption patterns at the site change over time.
