Environmental and Sustainability Report

MGE has issued its 2017 Environmental and Sustainability Report update. The report provides a comprehensive view of our efforts from recycling to clean water initiatives to community engagement. Below are some of the highlights:

Emission Reductions

MGE has made significant strides in reducing emissions. From 2005 through 2016, MGE has:

  • Decreased carbon dioxide emission rates 21%
  • Decreased regulated air emission rates:
    • Sulfur dioxide: 97%
    • Nitrogen oxide: 60%
    • Particulate matter: 93%
    • Mercury: 94%
Energy 2030

MGE developed its Energy 2030 framework to guide our energy future. Under Energy 2030, we set these goals:

  • Reduce CO2 by 40% from 2005 levels by 2030. This target is consistent with U.S. emissions targets for the 2030 time frame established as part of the Paris Agreement on climate change.
  • Increase renewable energy—supplying 30% of retail electric sales with renewable energy by 2030.
U.S. Mid-Century Strategy for Deep Decarbonization

The U.S. Mid-Century Strategy (MCS) for Deep Decarbonization is the United States' strategy for meeting the goals of the Paris Agreement on climate change to limit global warming to two degrees Celsius. MGE's long-term trajectory is aligned with the MCS, which identifies greenhouse gas emissions reductions of 80% by 2050 (from 2005 levels).

MGE is committed to reducing carbon dioxide emissions at least 80% by 2050. If we can go further faster by working together with our customers, we will.

Working Toward Energy 2030

We are working toward our Energy 2030 goals, which were first announced in 2015:

  • New Wind Farm: MGE is building a 66-megawatt (MW) wind farm near Saratoga, Iowa. The wind farm is expected to become operational in early 2019. The investment will grow MGE-owned wind generation by 160%.
  • Wind Farm Purchase: We also are purchasing a share of the Forward Energy wind farm in Wisconsin to help provide cost-effective clean energy to our customers. When combined with Saratoga, this grows our MGE-owned wind generation by more than 200%.
  • Solar Projects: We plan to seek regulatory approval in 2018 to build two large solar projects with WEC Energy Group. We expect MGE's ownership share to be at least 50 megawatts, or enough to serve about 16,500 households.
  • Community Solar: MGE's Shared Solar pilot project in partnership with the City of Middleton, Wis., came online in early 2017. MGE is pursuing additional projects.
  • Transition from Coal: As part of its transition away from coal-fired generation, MGE reduced its ownership share in the Columbia Energy Center, one of two coal plants in which MGE is a minority owner. MGE has no controlling interest in coal-fired generation and has no plans for additional coal resources.
  • New Technologies: From electric vehicles to smart home technology, MGE is advancing new technologies and bringing additional value to our customers.
