WEC Energy to build 250 MW Darien Solar Energy Center with 75 MW battery storage in Wisconsin

We Energies and Wisconsin Public Service (WPS), subsidiaries of WEC Energy Group (WEC), have proposed to build a 250 MW solar and 75 MW battery storage project to be built in Rock and Walworth counties, Wisconsin.

If approved, the US$446 million Darien Solar Energy Center would feature 250 MW of solar generation, which is equal to powering 75,000 homes, and 75 MW of battery storage.

The We Energies and Wisconsin Public Service (WPS) has filed the Darien solar and battery storage proposal to the Public Service Commission of Wisconsin. If approved, WEC Energy Group utilities We Energies and Wisconsin Public Service would own 90% of the project. Madison Gas and Electric would own the other 10%.

The project is being developed by Invenergy. If approved, construction is expected to begin in late 2021, and the project is scheduled to go into service by the end of 2023.
