Wisconsin Launches First Large-Scale Battery Storage System in
We Energies has launched Wisconsin''s first large-scale battery storage project at the Paris Solar-Battery Park in Kenosha County, which became operational in June 2025. This
The 110-megawatt (MW) battery portion of the Paris Solar-Battery Park went online this month. The 200-MW solar portion of the project went into service in December. The storage facility is made up of batteries capable of powering more than 130,000 homes for four hours.
The park's 12,000 lithium-ion batteries can power over 130,000 homes for up to four hours. We Energies, the majority owner, plans to discharge the batteries multiple times per week. The accompanying Paris Solar Park, with nearly 50,000 solar panels, provides the energy stored in the batteries.
We Energies, the state's largest utility, is the majority owner of the Paris Solar-Battery Park. Two other utilities, Wisconsin Public Service and Madison Gas and Electric, are co-owners. The Paris Solar Park provides the energy stored in the batteries. It has nearly 500,000 solar panels and has been in operation since December.
