Net Metering

Solar 101 How Sunlight Becomes Solar Power

Net metering allows REC 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 REC. 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.


Maximum Sizes

For standard residential net metering applications, the maximum generator size is 20 kW. The maximum allowable generator size for those on nonresidential tariffs is one megawatt (1000 kW).

For Net Metering purposes, members may own and operate, or contract with someone else to own and/or operate a renewable fuel generator.

At no time will REC's meter usage data provide the output of the member's renewable generator. The utility meter will only measure the energy used less the energy generated.


House uses 1500 kWh – Renewable Generator produces 1000 kWh = REC will bill the member 500 kWh for that month.

House uses 500 kWh – Renewable Generator produces 1000 kWh = REC will bill the member 0 kWh for that month and will carry forward a 500 kWh credit to the next month.




When considering installing a Net Metering system, members should carefully review and understand the Net Metering Virginia Code.
