Abstract: A system by which an electric power utility can selectively limit power supplied to homeowners or other users to conserve electricity in periods of higher usage/shortages. Each home that is participating in the system has “smart switches” installed at outlet locations, for example, a stove, clothes dryer, television sets, lamp, etc. The power utility sends communications either through cell phone technology, telephone, or other communication link to the home to signal the various smart switches to limit electrical output (either blocking current flow totally, or periodically). The electric utility sends its communication to a monitoring and control computer which in turn controls the various smart switches. Also, information of power usage is transmitted to the smart switches back to the utility company so that bills can be prepared, with savings also specified in the bill.
