Net Excess Generation Notes

A. All kWh delivered by the Cooperative to the Customer during a billing cycle will be billed at the Cooperative' s applicable Standard Rate Schedule for the service provided to the Customer.


B. All kWh received from Customer by the Cooperative (Excess Generation) will be credited on the monthly customer bill by the Cooperative at the ACC approved AER or, if less than the AER, the energy charge paid by Customer to the Cooperative, adjusted by the applicable purchased power and fuel cost adjustor. The credit shall be applied against the Cooperative monthly charges. No Excess Generation shall be "banked," "saved" or "rolled forward" for use in a future month. In the event the credit exceeds the amount due the Cooperative (Excess Credits), the credit shall be rolled forward and applied against subsequent Cooperative bills until used. After the customer's December bill, a customer may request a compensation for any outstanding credits from the prior year; if the outstanding credits exceed $25, a check will be automatically issued, otherwise the bill credits will carry forward to the following year.

System Offset Notes

10 kW DC for residential or 125% offset (whichever is less)


125% Max Sizing Calculation: In the absence of demand data (for residential and small business) the highest 12 months (Calendar Year) kWh consumption in the previous three years will be divided by 2190 (to determine the 100% capacity level in kW which will achieve a “net zero” home or business) and multiplied by 125%. For customers with a demand history it will be 125% of the highest demand in the most current 12 month period.

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with Navopache Electric Cooperative 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.
