Solar and battery projects


The following are solar and battery storage energy projects that serve Wisconsin and Upper Peninsula of Michigan customers. Solar energy projects utilize solar cells, also called photovoltaic (PV) cells to convert sunlight into electricity. PV gets its name from the process of converting light (photons) to electricity (voltage). Solar panels have tracking systems that allow the panels to move throughout the day as the sun changes position in the sky. This energy can be used to generate electricity or be stored in batteries for use after the sun sets. We currently have a capacity of 718 megawatts (MW) of solar generation.

Solar Now

Solar Now is our innovative program that produces clean energy for all customers. Through Solar Now, we partnered with large business, nonprofit and government customers to host solar panels. We leased space for the panels on roofs and unused land. Working with customers across the state, we completed projects with numerous partners including Harley-Davidson, University of Wisconsin-Parkside, City of Racine, School District of New Berlin, and Washington County.

Solar Now is a pilot program that was approved for up to 35 MW. The program is now at full capacity, and the Public Service Commission of Wisconsin voted to not expand it in late 2022.

Distributed energy resource sites

Distributed energy resources are smaller solar sites, averaging about 7.5 MW, that connect renewable solar energy directly to distribution lines into local communities.
