WEC Energy Group plans to build Wisconsin's first large-scale solar and battery storage project

WEC Energy Group is set to build a new 310-megawatt (MW) solar and battery storage project. If approved, the Paris Solar-Battery Park in Kenosha County would be the largest facility of its kind in Wisconsin.

The facility features 200 MW of solar generation — which is equal to powering 60,000 homes, and 110 MW of battery storage — which can store solar-generated power and discharge it when the sun goes down, providing customers with "sunshine after sunset."

The company filed the battery and solar storage proposal today with the Public Service Commission of Wisconsin. If approved, WEC Energy Group utilities We Energies and Wisconsin Public Service would own 90 percent of the project. Madison Gas and Electric would own the other 10 percent.

The project is being developed by Invenergy. If approved, construction is expected to begin in 2022 and the project is scheduled to go into service in 2023.
