If you are interested in installing your own electric generating system – such as a wind turbine, solar system or biogas system – you need to follow several steps to "interconnect" to the WPS electric distribution system.

The following information will guide you through the required steps and requirements to ensure everybody's safety.

For systems 20kW or less (Category 1 projects)

  1. Start the interconnection process.
    Contact Corey Kuchta at 920-433-2913 or CJKuchta@wisconsinpublicservice.com to review your project.
  2. Review the rates and requirements.
     
  3. Complete the interconnection application.
    Submit the completed application and application fee, to: Corey Kuchta, WPS, P.O. Box 19001, Green Bay, WI 54307-9001.
     
  4. Review interconnection options and costs.
    After the completed application is received, we will contact you to discuss the interconnection options available and their associated costs.
  5. Install generator.
    Together, we will determine an agreed-upon timeframe in which your generating equipment will need to be installed. After installation, we will perform any work needed to upgrade our distribution system to accommodate your system.
  6. Complete the interconnection and operating agreement.
    Submit the completed Interconnection and Parallel Operating Agreement to: Corey Kuchta, WPS, P.O. Box 19001, Green Bay, WI 54307-9001.
  7. Have your generating system inspected.
    Before electric generation can begin, WPS will need to receive proof of approval from the local building or electrical code inspector. With this approval, we will complete the interconnection.

For systems greater than 20kW

  1. Start the interconnection process.
    Contact Corey Kuchta at 920-433-2913 or CJKuchta@wisconsinpublicservice.com to review your project.
  2. Review the WPS generation rates and requirements.
  3. Review the state of Michigan interconnection requirements.
  4. Complete the interconnection application and operating agreement.
    Submit the completed application and application fee to: Corey Kuchta, WPS, P.O. Box 19001, Green Bay, WI 54307-9001.
     
  5. Determine if distribution study is needed.
    After the completed application is received, we will determine if a distribution study is needed to further assess your system's impact on our electric grid. Your written authorization, and the applicable fee, will be needed to complete the study.
  6. Review interconnection options and costs.
    We will contact you to discuss the interconnection options available and their associated costs.
  7. Installation generator.
    Together, we will determine an agreed-upon timeframe in which your generating equipment will need to be installed. We will perform any work needed to upgrade our distribution system to accommodate your system.
  8. System testing.
    After installation is complete, WPS must be notified and given the opportunity to witness or verify the system testing, which could include:
     
    • Witnessing commissioning tests;
    • Performing anti-islanding tests; or
    • Verifying the protective equipment settings.
