This paper was inspired by the incessant cries of electricity utilities who are losing billions of dollars due to power losses and, in particular, power theft. A visit to the UMEME lab found that meter manipulation was stealing considerable quantities of energy. While the meters in use at the time were fitted with an anti-tampering system, the customer was intended to be disconnected if the meter was tampered with. In the event that one wished to tamper, this did not always work. In this paper, a system that ensure continuous monitoring of users' energy consumption, identifying any attempts to tamper with the meter, and send reports about the current status of the metering system to the power company was designed and implemented.
