Corporate Responsibility and Sustainability Report

MGE's Corporate Responsibility and Sustainability Report details our corporate responsibility, environmental leadership and sustainability goals. It also covers our clean energy investments and partnerships with customers and other stakeholders to advance sustainability through energy efficiency, new technologies and other ways.

Net-zero carbon electricity by 2050

MGE is on the path toward deep decarbonization, pursuing globally recognized strategies to achieve an ambitious goal of net-zero carbon by 2050. Our deep decarbonization goal is consistent with climate science. And, consistent with the science, we fully expect to achieve carbon reductions of 65% by 2030. 

Both the Intergovernmental Panel on Climate Change (IPCC) and the U.S. Mid-Century Strategy (MCS) for Deep Decarbonization rely on decarbonizing electric generation, using energy efficiently and electrifying other energy uses, including transportation. These are the strategies MGE is pursuing and will continue to pursue to achieve deep decarbonization.

​"Our goal reflects our vision and signals our direction, but it does not determine our pace. We're making decisions every day to achieve deep decarbonization as quickly and cost-effectively as we can while working to ensure all customers benefit from the use of new technologies and investments in clean energy," MGE Chairman, President and CEO Jeff Keebler said.

Analysis by the University of Wisconsin-Madison

The University of Wisconsin-Madison evaluated MGE's goal of net-zero carbon electricity by 2050, comparing it to the modeled pathways for the electricity sector in industrialized nations to limit global warming to 1.5 degrees Celsius. The UW's analysis determined, relative to publicly available model results for carbon reductions through 2050, MGE's goal is in line with or more aggressive than these model benchmarks for climate solutions. 
The models suggested that by 2050 emissions from electricity generation in industrialized countries should be 87% to 99% lower than the 2005 baseline. MGE's plan for net-zero carbon emissions by 2050 is a 100% reduction from 2005 levels, which reflects carbon reductions consistent with limiting global warming to 1.5 degrees Celsius to prevent the most severe impacts of climate change. 

Report highlights

The 2021 report features information about MGE's corporate strategy and climate-related matters; safety and operations; metrics and targets; customer and employee engagement; risk management; and governance and oversight. Highlights include: 

  • MGE expects to achieve carbon reductions of at least 65% by 2030, consistent with global climate science. MGE already has reduced carbon emissions 30% from 2005 levels. 
  • MGE is decarbonizing its electricity generation, projecting an estimated total of $565 million in nearly 400 megawatts (MW) of wind, solar and battery storage between 2015 and 2024. 
  • As a minority owner, MGE is working with the co-owners of the Columbia Energy Center to retire the coal-fired plant by the end of 2024. By 2030, MGE’s remaining use of coal is expected to be reduced substantially. We expect to eliminate coal as an energy source by 2035 when the Elm Road Generating Station stops using coal. MGE is a minority owner of Elm Road. 
  • MGE employees achieved historic safety results in 2020. Despite working through a global pandemic, we recorded our lowest-ever recordable incident rate. 
  • MGE’s electric service reliability is ranked number one in the country for both the fewest number of outages and shortest duration of outages per customer in 2020, according to an annual industry survey. 
  • MGE earned the Green Master designation in 2021 for the eighth consecutive year from the Wisconsin Sustainable Business Council. Only the top 20% of applying companies receive the Green Master designation. 
  • MGE’s philanthropic arm, the MGE Foundation, has given more than $6.7 million to more than 400 community organizations in the last five years. 
  • MGE is advancing electric transportation with a robust customer education program, a home charging program and a public charging network. MGE also has an electric vehicle (EV) fleet goal of 100% all-electric or plug-in hybrid light-duty vehicles by 2030. 

MGE is participating in the Edison Electric Institute's (EEI) environmental, social, governance and sustainability-related reporting templates. The voluntary, industry-specific templates provide current data and information on MGE operations and other matters.

  • Quantitative template: includes data related to MGE’s energy portfolio (generation and capacity), emissions, capital expenditures, and human and natural resources.
  • Qualitative template: includes information related to our company’s management and oversight of and strategies for transitioning toward deep decarbonization and greater sustainability.
