Net Excess Generation Notes

For accounts not on a Time of Use rate the energy consumed and generated offset each other, kWh for kWh, and over-generation is “banked” for future use. If the member generates more than they consume, their generated kWh that exceeds consumption is “banked” to offset usage in the future months when the member generates less than they consume. At the end of the 12 months, any unused excess kWhs banked will be paid out to the member at the avoided cost of the previous 12 months (assumption $0.03)

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with Eau Claire Energy Cooperative (WI) 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.
