US utilities plot remote switch off
"HomePlug, the networking standard for sending data over mains wires, is to implement ZigBee’s Smart Energy protocol, allowing utilities to reach out and the thermostat turn down, or up, when power is short. An array of US utility companies is pushing the initiative, which sees HomePlug extending ZigBee Smart Energy to work over electrical mains wiring and integrating with ZigBee-based devices. The standard allows utilities to reach out and control non-critical devices when needed, such as pool pumps, thermostats and water heaters."
