Abstract

Energy commodities in the form of electricity and combustible fuel (e.g. natural gas, propane) are used by appliances in a fashion which is monitored and controlled through a Premises Energy Management System (PEMS). The system facilitates direct monitoring and control of energy-consuming appliances, in real time, utilizing automated programmatic control and a plurality of human interfaces including local display and control, email, web browser, text messaging, and integrated voice response (IVR). A Monitoring and Control Coordinator (MCC) provides centralized coordination of functions and one or more Communicating Appliance Interfaces (CAI) interacting with energy consuming appliances are interconnected via wired and wireless communication networks and protocols. The system may retrieve information from third parties, such as weather services, for optimizing energy usage. An interface may be provided to the energy provider/purveyor to enhance the provision of energy by providing additional real-time services such as demand management and service outage management.
