Renewable Energy & Battery Storage Systems

Through a net metering agreement, United Power members can connect their independently owned renewable energy generating or battery storage systems directly to the utility distribution system. At this time, United Power does not offer a rebate for new system installations.

To interconnect to the distribution system a member must complete the corresponding application and follow all requirements associated with that system. In addition, members will be required to sign the application and agree to the United Power Net-Metering/Interconnection Terms and Conditions.

Note: Systems connected without proper notification to United Power will be immediately disabled, and can result in service being terminated to the member until all requirements are met. Read more about the importance of meeting safety requirements for interconnected systems.

Application and Terms & Conditions

>>Effective January 1, 2018 the Interconnection Fee will increase to $200.


Net-metering allows a member to offset their electric usage through on-site generation of electricity through solar, wind, biomass, 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. United Power has allowed net-metering for well over a decade and in many cases exceeds the limits placed on it by the State of Colorado.  The benefit of net-metering is that any excess generation is immediately registered by the member’s meter and the member receives the full retail value of the generated electricity.

Net-Metering Policy Summary

  • System generation can not exceed 120% of the annual usage at that location.
  • On a monthly basis, excess kwh’s will be rolled over to the next month for future use at the member’s applicable rate.  A member’s minimum bill will be the associated fixed service & facility charge for that member’s rate.
  • On an annual basis (expressed in an Apr – Mar period), a member that continues to have excess generation will be cashed out at the wholesale energy rate. (In 2017 this cashout rate was approx – $.042/kwh)


  • Any projected value of the electricity produced by these systems is not guaranteed by the utility.  Changes in rates, rate structures or net-metering policy could affect this value and existing practices will not be grandfathered.

Battery Storage Systems

For any members looking to add battery back-up systems, United Power requires a Renewable Energy/Battery Storage application be completed. Although batteries are used for back-up, they can run parallel to the grid and United Power must be aware of the equipment.
