Solar System Rebates and Net Metering


Photovoltaic rebate funding has been allocated for the year (Oct. 2016 – Sept. 2017). Please submit your rebate and net metering application to be placed on the rebate waiting list in case additional funding becomes available.

Columbia Water & Light offers a one-time $500 per kilowatt rebate for qualifying solar energy systems. There is a 10 kilowatt cap on Columbia Water & Light’s solar energy system rebate. If you are planning to install a larger system, please contact us about the possibility of a special arrangement. Columbia Water & Light also offers low-interest loans to help you finance your project.

Net Metering

Columbia Water & Light will pay the customer’s current applicable electric rate for the electricity generated by the customer’s solar energy system that is delivered to Columbia Water & Light. This arrangement offers the customer more than what the Missouri Statutes for net metering require. A Net Metering Agreement must be approved by the utility for the customer to receive a credit for the energy they generate. There is a 100 kilowatt capacity cap on the net metering arrangement and the utility retains the renewable energy credits for the project. If a customer wants to retain the renewable energy credits for a solar energy system, the electric generating rate credit will be based on the avoided average energy market price at the Columbia pricing node. For more details, see our net metering information.

Signing up for net metering & rebates

The Process
  • Study photovoltaic systems and evaluate your energy consumption history.
  • Contact several contractors that install PV systems. This will give you an idea of what type will work best for your location, the size and cost of the system.
  • Review the parameters of the guidelines of the rebate program listed below and the net metering information with your contractor.
  • Fill out and submit the Net Metering & Rebate Forms, the form with details about your PV system and the site diagram to Columbia Water & Light. Note: you can use your computer to fill out the forms but you must print and sign the Interconnection and Net Metering Agreement.
  • Columbia Water & Light staff will review your proposal and give you approval for interconnection and a rebate or notify you of any changes needed to meet the guidelines.
  • After approval from Columbia Water & Light for net metering and the rebate, work with your contractor to obtain an electrical permit from Columbia’s Community Development Department’s Building and Site Development Division.
  • Upon receiving an electrical permit from the Building and Site Development office, you can proceed with the installation of the PV system.
  • After completion of the installation, contact the Building and Site Development office to schedule a final code inspection for your electrical permit.
  • Upon receiving final approval from the Building and Site Development office, contact Columbia Water & Light at 573-874-7325 to schedule a rebate inspection. At this time you will be required to supply an invoice for the PV system, a copy of the final electrical code inspection and a copy of the insurance certificate if the system is rated above 10 kilowatts. The rebate application will be completed by our staff at the final rebate inspection.
Rebate and Net Metering Guidelines
  • Listed below is the order in which you need to proceed with your PV project to receive a rebate and enter into a net metering agreement. Please review the Interconnection & Net Metering Agreement for a detailed list of requirements for PV systems that are attached to the Columbia Water & Light electric distribution system.
  • Interconnection Standards: The PV system should comply with the following standards:
    • National Electric Code (NEC) including but not limited to, NEC Articles 690 (Guidelines outlining the installation of the system including structural and electrical components) and NEC 705 (regarding the safety and warning signs of the system).
    • Underwriters Laboratories (UL) including but not limited to, UL 1741 (Standard for Static Inverters and Charge Controllers for Use in Photovoltaic Systems), and UL 1703 (Standard for Safety: Flat­ Plate Photovoltaic Modules and Panels).
  • Institute of Electrical and Electronics Engineers (IEEE) Standards including, but not limited to 1547­2003 (Standard for Interconnecting Intellect Systems).
  • An Interconnection & Net Metering Agreement, the appropriate system information page and the site diagram must be submitted and approved by Columbia Water & Light.
  • To receive the customer’s current applicable electric rate for the electricity generated by a customer’s solar system, the customer must agree not to sell or transfer any Renewable Energy Credits associated with the PV system.
  • Photovoltaic panels must come with a 25-year or greater manufacturer’s warranty. All grid-tie, sine-wave inverters must come with a minimum 10-year manufacturer’s warranty.
  • The solar modules and inverter must be new and listed as eligible solar energy equipment on the California Energy Commission’s Go Solar website.
  • Paid receipts for the system and a copy of the final electrical code permit must be submitted at your final rebate inspection. The receipt must list the model numbers for the installed equipment. A copy of the insurance certificate is required for systems rated over 10 kilowatts.
  • Columbia Water & Light offers a one time solar rebate to qualifying electric customers. Rebates are offered on a first come, first serve basis as funding is available each fiscal year.
  • Copies of the receipts and the final code inspection must be submitted to Columbia Water & Light within six months of the solar electric system’s installation. If there is incomplete or incorrect information submitted, customers will have thirty days to provide the correct information or risk losing their place in the rebate funding process.
