If you are interested in installing your own electric generating system – such as a wind turbine, solar system or biogas system – you will need to follow several steps to "interconnect" to the WPS electric distribution system.
The following information will guide you through the steps and requirements to ensure everybody's safety.
The interconnection process can seem overwhelming at first, but WPS partners with Focus on Energy to help connect you with experts on renewable energy systems and Cash-Back Rewards for installations.
For systems 20kW or less
- For any questions regarding this process please contact:
- Review the parallel generation rate
- Review and understand the rules and requirements
- If the Application is less than 20kW, complete the following form, mail and/or send via email to:

Menominee, MI 49858
- Required - Wisconsin Standard Distributed Generation Application Form
- Required - Select Supplement applying for (select one or more):
- Required only if installing - Energy Storage Supplement Form
- Required only if new ownership is acquired. Skip 5-7 if using this form - Change of Ownership Form
- Interconnection Agreement -
Distributed Gen Interconnect Agree 20kW or less
- WPS reviews the application
WPS will review your
application to determine if it contains all the information needed to begin the
interconnection process. WPS
will contact you about the status of your application. If the application is
incomplete, additional information will be requested.
- WPS determines if a distribution study is needed
After your application is considered complete, WPS
will determine if a distribution study is needed. This study is to assess the level of impact
your system will have when it's connected to the grid.
If the study is needed, WPS will
inform you about the cost of the study. After you have provided written authorization to proceed
and paid the applicable fee, we'll complete the study.
- Discuss distribution study and review interconnection options and costs
Once the distribution study is complete, WPS
will contact you to discuss all of the options available – along with their associated
costs – and the timeline for the interconnection of your parallel generation system.
- Install parallel generation and distribution system upgrades
You will need to install your generating equipment within a mutually agreed upon timeframe. After
receipt of payment for the agreed-upon interconnection costs, WPS
will perform all work needed to upgrade the distribution system to accommodate your parallel
generation system.
- Sign the interconnection agreement
Before parallel operation can begin, both you and WPS
will need to complete and sign a standard interconnection agreement and power purchase agreement.
- Test the system
When the installation of your system is complete, send Certificate of Compliance or local inspector verification to Corey Kuchta and notify local WPS engineer so we can witness or verify the system testing. This could include:
- Witnessing commissioning tests.
- Performing anti-islanding tests.
- Verifying the protective equipment settings.
