MGE Continues to Grow Its Use of Solar Energy

Solar panels

In March, Madison Gas and Electric (MGE), in partnership with We Energies and Wisconsin Public Service (WPS), subsidiaries of WEC Energy Group, received approval from the Public Service Commission of Wisconsin (PSCW) to purchase solar capacity from the Good Oak and Gristmill solar farms. 

Good Oak Solar Farm

The 98-megawatt (MW) Good Oak Solar Farm will be located in the Town of Lewiston in Columbia County. MGE will own 9.8 MW of solar capacity. It is expected to begin serving customers in 2028. 

Gristmill Solar Farm

Located in the Town of Columbus in Columbia County, MGE will own 6.7 MW of solar capacity from the 67-MW solar array. It is expected to begin serving customers in 2028. 

"Partnering helps MGE grow cost-effective solar energy to support our ongoing sustainable energy transition," said Jeff Keebler, MGE Chairman, President and CEO. "MGE is committed to using renewables first and ensuring reliability for all customers while maintaining energy affordability. With our current plans, by 2030, we will have added more than 40 renewable generation and battery storage projects since 2015, totaling more than 750 MW, propelling us toward our goal of net-zero carbon electricity by 2050." 

Dawn Harvest Solar Energy Center

The approval for these two projects comes after the PSCW's approval of the Dawn Harvest Solar Energy Center earlier in the month. MGE will own 15 MW of solar capacity from the 150-MW solar array in Rock County, Wis. We Energies and WPS will own the remaining solar capacity. The Dawn Harvest Solar Energy Center is expected to begin serving customers in 2028. 

Ongoing Investment

By continuing to invest in geographically diverse utility-scale renewable generation projects, MGE is enhancing reliability, managing costs and accelerating the transition to a low-carbon future. These efforts are part of a broader strategy that includes: 

  • Expanding renewable energy.
  • Advancing energy efficiency.
  • Supporting the electrification of transportation. 

Together, these initiatives help reduce carbon emissions and support a more sustainable Wisconsin.
