Net Excess Generation Notes

The Company will carry forward negative kilowatt-hours until the Customer’s consumption of electricity from the grid eliminates the Excess Generation or until the end of the billing cycle that is completed immediately prior to the end of April of each year. For Customers served under Standard Offer Service, the dollar value of Excess Generation shall be equal to the Supply Capacity, Energy and Ancillary Rates portion of the rate that the Customer would have been charged averaged over the previous twelve-month period ending with the billing cycle that is complete immediately prior to the end of April multiplied by the number of kilowatt-hours of Excess Generation. For Customers served by alternate suppliers of electricity supply service, the dollar value of Excess Generation shall be equal to the electricity supply service portion of the rate that the Customer-generator would have been charged by the electricity supplier, if that rate is known by the Company, multiplied by the number of kilowatt-hours of Excess Generation.

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with Delmarva Power (MD) before you rely on this. The useful move: if an installer says you need a main panel upgrade, ask how these tap and interconnection policies were considered first.
