Date Last Updated8/12/2014
Policy TypeNet-Metering Policy
State/FederalD.C.
Policy Administrator/Contact OfficeDC Public Service Commission
Policy Initiation Date2/18/2005
Policy SummaryIn the District of Columbia, net-metering is available to residential and commercial customer-generators with systems powered by renewable-energy sources, CHP, fuel cells and micro turbines up to 1 MW in capacity (a 5 MW limit applies to community renewable energy facilities). There is no specified aggregate capacity limit of net-metered systems.

The District's net-metering rules specify that metering equipment must be capable of measuring the flow of electricity in two directions. Utilities are not prohibited from installing an additional meter on the facilities of eligible customer-generators, but utilities that choose to do so must pay for the added cost of the second meter and/or other necessary equipment. Compensation for monthly net excess generation (NEG) varies based on the size of the generator. For systems up to 100 kW, NEG is credited to the customer's next bill indefinitely at the full retail rate, which includes generation, transmission, and distribution components. For systems with capacities >100 kW, NEG is credited to the customer's next bill at the generation rate. Utilities must offer a standard net-metering contract approved by the D.C. Public Service Commission.
CHP Eligibility RequirementsBoth fossil-fueled and renewably-fueled CHP systems are eligible for net-metering.
Eligible Project Size (MW)Systems up to 1 MW are eligible to net-meter and community renewable energy facilities up to 5 MW.
