Wisconsin’s First Large-Scale Solar Plus Storage Project Advances

WEC Energy Group and Madison Gas & Electric (MGE) filed with the PSC  to purchase the Paris Solar-Battery Park for roughly $400 million. The 310 MW solar plus storage project includes a 200 MW PV farm, which would generate enough electricity to power approximately 60,000 homes, and a battery system to store enough energy to supply 110 MW for up to four hours. This provides resilience to the grid in times when the sun isn’t shining, the grid goes down, or at peak times when more power is needed. The solar farm will be built by Invenergy in 2022 in the Town of Paris in Kenosha County on about 1500 acres.
We Energies and Wisconsin Public Service Corp (WPS)- both WEC subsidiaries, would invest $360 million to own 90 percent of the project and MGE would own 10%. These utilities have set goals to achieve 100 percent carbon-neutral electricity by 2050. WEC plans to replace 1.8 gigawatts of coal capacity with solar, wind, battery and natural gas resources with $2 billion in investments in new solar, wind, and battery projects by 2025. biztimeswsj
