Net Excess Generation Notes

For each billing period, the Consumer’s monthly energy generated by Consumer’s Eligible Generation Source for that billing period will be credited by an amount per kilowatt-hour at the Cooperative’s stated rate as outlined in section below. Cooperative shall review the cost of service based rate at least annually to ensure rate reflects the appropriate cost.


As of the Effective Date of this Rider (June 1, 2022), monthly generated energy shall be credited at the Cooperative’s rate of:

  • Summer Months (June through September) @ 8.0¢ per kWh
  • Winter Months (October through May) @ 5.0¢ per kWh 


If the solar credit is larger than the energy bill, the remaining credit rolls over to the next month as long as the account remains active.

The size of the array is checked by me based on the average of the Highest PEAK demand meter readings

If the system is too large we will not approve the application.

To qualify for service under this Rider, the Nameplate Rating of the Consumer’s installed generation system and equipment must not exceed the Consumer’s actual or estimated average (12)-month non-coincidental demand (kW) or 20 kW for a residential consumer or 1,000 kW for a non-residential consumer, whichever is less
