Net metering allows MEC Members to interconnect approved renewable generation systems to the electrical distribution system and to generate some of their own electricity. The output of the renewable generation system offsets the electricity that would have been delivered by MEC. Common examples of net metering installations include solar panels on a home or a wind turbine at a school.
These installations are connected on the member's side (the usage side) of the meter. The meter will rotate forward to measure electricity being used from the grid, and it will reverse when the customer generates excess electricity (thereby “exporting” electricity to the electric grid). The sum, or "net," of the forward and reverse rotation is the volume of electricity (kWh) to be billed or credited to the monthly bill.
