What is the Paris energy project?
The Paris energy project is an opportunity to invest in the community, create jobs, and increase tax revenues while generating clean, American made energy. The project is located in the Town of Paris, Kenosha County, Wisconsin, north of and adjacent to State Highway 142 and west of Interstate Highway 94.
We Energies announced on Tuesday that the Paris Solar-Battery Park in Kenosha County has started serving customers on the energy grid. While the 200-megawatt solar portion of the project started service in December, the 110-megawatt battery portion hadn't been put into service yet. Now, officials say it's powering the energy grid.
Where is Wisconsin's first large utility-scale battery storage project?

We Energies announced Tuesday that the last major piece of the Paris Solar-Battery Park in Kenosha County was online.
How does Paris Solar-Battery Park work?
The Paris Solar-Battery Park can power more than 130,000 homes for four hours, according to We Energies. Officials explained the way the storage facility works. They said that batteries store excess power on sunny days. Then, that power is released at night or in the early morning when the sun isn't out.
Beyond the Paris project, WEC Energy Group has several more battery storage projects in development, ranging from 50 megawatts to 165 megawatts of storage. Those projects are slated to come online from 2026 through 2028. The battery storage systems at the Paris Solar-Battery Park in Kenosha County are seen in this image captured by a drone.
