Celebrating Sustainable Energy

MGE's Top of Iowa wind farm celebrates ten years as MGE adds more wind and solar energy.

This year marks ten years since MGE's Top of Iowa wind farm in northeast Iowa came online. The 18 turbines began generating energy in February 2008. The 30-megawatt (MW) wind farm helped MGE increase our wind resource capacity by 12 times that year.

Top of Iowa and four other wind farms continue to serve MGE customers with clean energy. MGE is building upon its record of increasing renewables with another wind farm  already under construction.

New Saratoga wind farm

At 66 MW, Saratoga is more than double the capacity of our Top of Iowa wind farm. When complete, its 33 turbines will produce enough energy to serve about 47,000 households.

Since MGE built its Rosiere wind farm, located in Kewaunee County, Wis., and Top of Iowa, wind turbine technology has become more efficient and cost-effective. Saratoga's taller towers and larger blades will produce more energy per turbine.

Saratoga's turbines are expected to arrive in late summer at the 8,300-acre site in northeast Iowa. The area is known for its favorable wind speeds. Saratoga is expected to come online by early 2019.

30% renewable energy by 2030

Saratoga will help MGE advance our goals under Energy 2030, our framework for a more sustainable energy future. Under Energy 2030, we have set the goal of 30% renewable energy by 2030. If we can go further faster, we will.

By working with our customers, we're also targeting a 40% reduction in carbon emissions by 2030, which is consistent with U.S. emissions targets under the Paris Agreement on climate change. Beyond 2030, we are targeting an 80% reduction in carbon emissions by 2050. MGE already has reduced our carbon emissions by more than 20% since 2005.

Solar at MGE

We're moving forward with clean energy for our own facilities as well. In late 2017, a nearly 450-panel solar array at our offices became operational. It will supply nearly 10% of the building's annual electric needs. In addition, we replaced approximately 50 panels on the solar canopy in our parking lot with a more efficient array capable of producing double the energy output.

The new solar installation is part of MGE's ongoing sustainability efforts for which we have been recognized as a Green Master for the fourth consecutive year by the Wisconsin Sustainable Business Council. MGE was the first utility in Wisconsin to be recognized as a Green Master by the voluntary statewide benchmarking program.
