Customer-owned renewable generation in Wisconsin

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.
