Green Tier

MGE is the only electric utility in Wisconsin to be awarded the highest participating level in Green Tier, the Wisconsin Department of Natural Resources' (DNR) environmental leadership program. MGE is one of only seven Wisconsin companies that achieved the "Tier 2" level.

By participating in the Green Tier program, we are continuing our voluntary commitment to superior environmental performance. In cooperation with the DNR, we have set goals to make significant environmental improvements.

In 2017, we agreed to another five-year contract with the DNR under the Tier 2 program. We entered the Green Tier program at the advanced Tier 2 status because of our established environmental management system. We are the only electric utility to have been a part of the DNR's Environmental Cooperation Pilot Program since 2002. We currently are expanding our Green Tier contract scope to cover all MGE operations.

Our current process improvements include:

  • Expanding our Environmental Management System (EMS) developed for our Blount Generating Station to all of our operations. This voluntary framework enhances our environmental performance by emphasizing employee training, procedures, communications and continuous improvement.
  • Purchasing electricity from a local manure digester, which reduces phosphorous runoff into local waterways and improves water quality. This project was made possible through the support of MGE, which purchases the locally produced renewable energy at a premium price to help subsidize the digester.
  • Offering our customers a mercury thermostat recycling program and removing old equipment containing mercury at Blount Generating Station.
