Net Excess Generation Notes

A customer’s net energy shall be calculated by subtracting the kWh of electricity the customer’s generator facility feeds back to the city’s system during a billing month from the customer’s metered usage of electricity supplied by the city. If the Customer’s net energy is negative during a billing month, only the energy charge of the customer’s standard service Schedule shall be calculated using the customer’s net energy supplied to the City. All other charges shall be applicable and charged as set forth in the Table of Rates (Electric) and calculated in accordance therewith. If the customer’s net billing under the standard service schedule is negative during the billing month, the negative net billing shall be allowed to accumulate as a credit to offset energy charges the customer incurs in future billing months. After eight consecutive billing months of accumulated credit, the customer may request a refund.

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with City of Westerville 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.
