Net Excess Generation Notes
  • The generated energy can only offset the energy used at the service on which it is connected, and cannot offset the energy used on another service or account.
  • The meter is read during its normal billing cycle. If the member is a net producer during any month, the member will continue to be billed for the customer access charge and the excess energy will be rolled forward (banked) and available to the member the following month. 
  • Every year in April, the cooperative reviews all net metered accounts. If the member has 4,000 or more banked kilowatt-hours (kWh) at the time of the April billing cycle, the member will receive a check for all excess energy above 1,000 kWh payable at a cost equivalent to the cost of electric energy purchased by Grand Valley Power during the preceding month.

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with Grand Valley Power 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.
