Net Excess Generation Notes

If the eligible member is a net seller of electricity during the billing period, the cooperative will calculate a monetary credit for any metered excess kilowatt-hours of electric energy delivered to the cooperative at a rate equal to the per kilowatt-hour energy charge as shown on the applicable month's SIPC power bill and apply such credit against only the electric energy charges derived specifically from the consumption of electric energy measured in units of kilowatt hours as denoted on a subsequent bill for service to the eligible member. The cooperative shall continue to carry over any unused amount of such credits and apply those credits to subsequent billing periods to offset only any electric energy-related charges derived specifically from the consumption of electric energy measured in units of kilowatt-hours due from the eligible member as denoted in the billing for those subsequent billing periods until all credits are used or until the end of the annual period, whichever occurs first.

At the end of the annual period that service is supplied by means of net metering, or in the event that the eligible member terminates service with the cooperative during an annual period, any remaining credits in the member's account shall expire and no credit or payment shall be due to the member for such expired credits.

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with Tri-County Electric Cooperative, Inc (IL) 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.
