Ever-Green’s Operations Scope

A change in ownership presented the opportunity to improve service reliability and cost effectiveness. With leadership from Ever-Green, MRMC Thermal made additional infrastructure investments that improve the reliability of steam and chilled water service, which are critical to the operation of the hospitals and research facilities on campus. A new plant was constructed to implement more energy-efficient natural gas operations, which will help moderate or reduce future energy costs and reduce greenhouse gas emissions, benefiting the medical center organizations and their patients. The plant produces steam and chilled water that heats and cools most of the buildings on the medical center campus.


  • 2015 Ever-Green Energy was hired to form a new utility. Ever-Green will operate, maintain, and manage MRMC Thermal.
  • 2016 Change of ownership, MRMC Thermal Services, Inc. purchased the Milwaukee County Power Plant from Wisconsin Energy Corporation
  • 2016 System recapitalization and conversion from coal to natural gas with construction of a new plant for the heating system, reducing greenhouse gas emissions by an estimated 50 percent.
  • 2016 Legacy coal fired system demolition and distribution network upgrade commencement
  • 2017 Major demolition completion, new equipment installation commencement
  • 2018 New equipment startups including electrical switchgear, boilers, chillers, diesel generators, cooling towers, control system, building systems, and distribution piping

Technology implemented: steam district heating, district cooling

“Here at Milwaukee Regional Medical Center we have many vendors, but only a couple strategic partners. For us, Ever-Green has been the very definition of strategic partner. They possess what I refer to as strategic empathy. That is, they embrace the strategic initiatives of their clients and provide real tangible value. This has been evident in Ever-Green meeting or exceeding every major milestone of our very complex $250 million central utility plant and distribution project. Time and again our team has given them large, complex goals and each and every time the Ever-Green team has risen to the occasion to achieve them. They understand our world of limited resources and consistently demonstrate an ability to prioritize initiatives and investments based on sound ROI metrics. Ever-Green’s commitment to excellence is evident at all levels of their organization, and their leadership team has been very intentional about creating a culture of accountability. Their integrity is beyond reproach.”
