MGE Plans Second Major Solar, Battery Project

A 250-megawatt project in southeastern Wisconsin would include up to 850,000 solar panels on 2,000 acres.

Madison Gas and Electric (MGE) plans to add more clean energy to our community grid with a new solar and battery storage project. MGE's share of the Darien Solar Energy Center would serve about 7,500 households. If approved by state regulators, MGE will own 25 megawatts (MW) of solar energy and 7.5 MW of battery storage from the 250-MW solar facility in southeastern Wisconsin.

"This is another step in our ongoing transition to greater use of cleaner energy sources and  our goal of net-zero carbon by 2050," said Jeff Keebler, MGE Chairman, President and CEO. "Further investment in cost-effective, clean energy and battery storage technology will allow us to continue reliably serving our customers as we work together to meet our carbon reduction goals. We have said since introducing our clean energy and carbon reduction goals—if we can go further faster, we will."


About the Darien Solar Energy Center

If approved, the Darien Solar Energy Center is expected to begin serving MGE customers by the end of 2023. We Energies and Wisconsin Public Service would own the remaining 225 MW of the output and 67.5 MW of battery storage from the project.
The proposal comes a month after MGE filed for state regulatory approval of its plans to purchase 20 MW of solar energy and 11 MW of battery storage from the 200-MW Paris Solar-Battery Park in Kenosha County. Both projects will help MGE to meet future energy and capacity needs cost-effectively as MGE continues its transition away from coal-fired electricity with the planned retirement of the Columbia Energy Center in Portage by the end of 2024. If approved, construction of the Paris Solar-Battery Park is expected to begin in 2022, and it is expected to begin serving customers in 2023.
