Apparatus (10) for controlling supply of electricity through an electrical distribution network to a customer. An electrical meter (12) is plugged into an electrical socket (14) at a customer's premises. Electricity flows from a power line through the socket into the premises, the amount of electricity used being measured by the meter. The apparatus is interposed between the meter and the socket and includes a switch (18) to interrupt flow of electricity into the premises. The switch is controlled by the utility, preferably through programming of the apparatus or through a TWACS® communication system. This enables the utility to selectively control supply of electricity to the premises apart from the flow of electricity to any other premises connected to the same power line (L).
