MGE Solar Projects

MGE owns and operates several solar arrays. We're also seeking to grow our use of solar energy to advance our renewable energy and carbon reduction goals.

Badger Hollow and Two Creeks Solar Farms

In May 2018, MGE announced plans to build two large solar farms in partnership with WEC Energy Group (WEC). In April 2019, state regulators approved the projects with construction expected to begin in 2019. 

  • Badger Hollow Solar Farm will be located in southwestern Wisconsin in Iowa County, about 12 miles west of Dodgeville. The first phase of this project received regulatory approval in April 2019. MGE and Wisconsin Public Service (WPS), a subsidiary of WEC Energy Group, will own a combined total of 150 megawatts (MW) of the 300-MW project. MGE will own 50 MW. This phase of Badger Hollow is expected to be operational in spring 2021.

    In August 2019, MGE and We Energies announced plans to acquire the remaining 150 MW of the Badger Hollow Solar Farm. In February 2020, MGE received preliminary approval from state regulators to purchase another 50 MW. This phase is expected to be operational by the end of 2022.
  • Two Creeks Solar Farm is located in the town of Two Creeks and the city of Two Rivers in northeastern Wisconsin. MGE's ownership share is 50 MW of its 150-MW output. Two Creeks became operational in November 2020.

Dane County Airport Solar

MGE also partnered with Dane County to construct 9 MW of solar on County-owned land adjacent to Dane County Regional Airport. This project was built under MGE’s new Renewable Energy Rider, an innovative model that gives large energy users and MGE the opportunity to partner to tailor a renewable energy solution to meet the customer's needs. Energy from the solar project serves the County. The array began delivering locally generated, sustainable energy in December 2020.
 

O'Brien Solar Fields

MGE is working with a developer to build a 20-MW solar project on approximately 160 acres of land located at Lacy Road and South Seminole Highway in Fitchburg. The project will deliver locally generated solar energy to large energy users through Renewable Energy Rider agreements. Construction started in in 2020. The solar array is expected to begin generating electricity in 2021. When complete, it will be the largest solar project in Dane County.

MGE is seeking regulatory approval for an agreement to partner with the City of Madison and the Madison Metropolitan School District (MMSD) to build an 8-MW solar array north of Dane County's Rodefeld Landfill in southeast Madison. The array will consist of nearly 28,000 solar panels and will cover 53 acres of land. If approved, the electricity generated by this local source of clean energy will increase renewable energy use in City operations by nearly 20%. The City will take 5 MW of the output and MMSD will take 3 MW of the output under Renewable Energy Rider agreements with MGE.



Paris Solar-Battery Park

Paris Solar-Battery Park

MGE, in partnership with We Energies and Wisconsin Public Service (WPS), is seeking regulatory approval to purchase solar energy and battery storage from the Paris Solar-Battery Park. If approved, MGE will own 20 MW of solar energy and 11 MW of battery storage from the 200-MW solar park to be built in the Town of Paris in Kenosha County. This partnership will help MGE to meet future energy and capacity needs cost-effectively as the company continues its ongoing transition away from coal-fired electricity with the planned retirement of the Columbia Energy Center in Portage by the end of 2024. MGE's share of the Paris Solar-Battery Park will power about 6,000 households. The project is expected online in 2023.  


Darien Solar Energy Center

Darien Solar Energy Park

In addition, MGE, in partnership with We Energies and Wisconsin Public Service (WPS), is seeking regulatory approval to purchase solar energy and battery storage from the Darien Solar Energy Park. If approved, MGE will own 25 megawatts (MW) of solar energy and 7.5 MW of battery storage from the 250-MW solar park to be built in the Town of Bradford in Rock County and the Town of Darien in Walworth County. The 2,000-acre project is expected to feature up to 850,000 solar panels. We Energies and WPS will own the remaining 225 MW of the output and 67.5 MW of battery storage from the project. The Darien Solar Energy Center is expected to begin serving customers by the end of 2023.   

Koshkonong Solar Energy Center

MGE, in partnership with We Energies and Wisconsin Public Service (WPS), also is seeking regulatory approval to purchase solar energy and battery storage from the Koshkonong Solar Energy Center. If approved, MGE will own 30 MW of solar energy and 16.5 MW of battery storage from the facility located in the Towns of Christiana and Deerfield in Dane County. The approximately 4,600-acre project will include a 300-MW solar array and a 165-MW battery storage system. It is expected to feature up to 730,000 solar panels. The project is expected to begin serving customers by the end of 2024.

Shared Solar Program

MGE's Shared Solar program offers the benefits of locally generated solar power. It's easy, flexible and affordable. Our first project, which came online in 2017, is a 500-kilowatt (kW) solar array located on the roof of the City of Middleton Municipal Operations Center. The program was expanded in 2020 with a 5-MW array built at Middleton Municipal Airport. Seventy percent of the Morey Field Solar array, or 3.5 MW, serves Shared Solar participants, with the other thirty percent being allocated to the City of Middleton and the Middleton-Cross Plains Area School District under our Renewable Energy Rider program. To participate, visit mge.com/sharedsolar.


 

Solar Lighting Proposal

We continue to explore innovative and environmentally friendly options for our customers. That's why we have an option for residential and business customers who want to add overhead solar lighting to their properties. MGE is able to partner with customers to design a customized lighting plan for large expanses.

 

Solar in Schools

We are committed to helping teach area students about renewable energy technologies. That's why the MGE Foundation has funded solar array installations for each of the 10 high schools in our electric service area.

 

 





Solar in Our Community

Live energy production data from several of our projects in the community is available on our website. These projects give us a better understanding of which equipment and mounting configurations work best in our climate and conditions. As solar technology continues to evolve, we continue to learn how we can best serve our customers with clean energy from the sun.
