## Abstract

An anti-theft system and method for encoding power for distribution to a load (e.g., a house) and a decoding of the encoded power at the load for consumption. A meter with an integrated decoder may be installed proximate a house (or another load). In some embodiments, the combination meter/decoder system may be configured to replace a traditional meter on a standard service panel, to minimize any impact or changes to the home or other building. In other embodiments, an add-on decoder system may be configured for installation between a standard meter and a service panel (optionally, plug and play). Alternatively, an add-on decoder system may be installed with the meter positioned (electrically) between the add-on decoder system and the service panel of the house (or other type of load or consumer).
