Generation Interconnection Policy

Net-metering allows a member to offset their electric usage through on-site generation of electricity from such sources as solar, wind, hydro, etc. In essence, net-metering allows a meter to spin forward when the member is a net user of energy or backwards when the member is a net generator of electricity. At the end of the month, a net-zero home would have spun the meter backwards as much as it was spun forward, essentially metering zero energy usage.  

In 2008, the State of Colorado ruled that electric utilities must accept a member’s generation (up to prescribed limits) through the use of net-metering. Grand Valley Power has allowed net-metering for over ten years. The benefit of net-metering is that any excess generation is immediately registered by the members meter and the member receives the full retail value of the generated electricity.


  • Available to residential and commercial members within the Grand Valley Power service territory.
  • The system must not exceed 10 kW for residential customers and 25 kW for commercial customers.
  • Member must apply for and then sign a Grand Valley Power Interconnection Agreement.
  • Proper local permits and inspections must be provided and documented to connect to the utility system.
  • 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 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.
  • The inverter and automatic disconnect must be UL 1741 approved.
  • An accessible, lockable, and visible AC disconnect must be installed to isolate the utility grid during times of emergency.
  • Once the system is installed and passes Mesa County electrical inspection, a Certificate of Completion must be returned to Grand Valley Power before final inspection is scheduled and the system is turned on.
  • Grand Valley Power will inspect the member disconnect and if necessary, change out the meter to an appropriate device before allowing the member to connect to the utility grid.
