MGE acquires the Koshkonong Solar Energy Center



Madison gas and electric (MGE) in partnership with WEC Energy Group subsidiaries We Energies and Wisconsin Public Service (WPS) has received approval from the Wisconsin Public Service Commission to purchase solar energy and battery storage from the Koshkonong Solar Energy Center.

MGE owns 30 MW of solar power and 16.5 MW of battery storage from a facility located in the cities of Christiana and Deerfield in Dane County.

“The Koshkonong Solar Energy Center continues the progress we’ve already made by reducing carbon emissions, increasing cost-effective use of renewable energy and developing new technologies to benefit all of our customers,” said Jeff Keebler, MGE President, CEO. “We are working aggressively to reduce our carbon emissions by at least 80% from 2005 levels by the end of this decade and to achieve carbon-free electricity by 2050.”

The project includes a 300 MW solar panel and a 165 MW battery storage system. It is expected to produce enough clean energy for around 90,000 households. MGE’s share of the production will serve approximately 9,000 households.

Me Energies and WPS own the rest of the project’s 270 MW of power and 148.5 MW of battery storage. Invenergy LLC is the developer of the project. The Koshkonong Solar Energy Center is estimated to start serving customers in late 2025.

The Koshkonong Solar Energy Center is one of three investments announced by MGE in large-scale solar energy and battery storage. MGE also owns a 10% stake in the Paris Solar-Battery Park and the Darien Solar Energy Center, both of which are under construction.
