Premises power usage monitoring system
A control system ( 300 ) allows recognized standard premise electrical outlets, for example NEMA, CEE and BS, among others to be remotely monitored and/or controlled, for example, to intelligently execute blackouts or brownouts or to otherwise remotely control electrical devices. The system ( 300 ) includes a number of smart receptacles ( 302 ) that communicate with a local controller ( 304 ), e.g., via power lines using the TCP/IP protocol. The local controller ( 304 ), in turn, communicates with a remote controller ( 308 ) via the internet.
