Milwaukee Regional Medical Center Thermal Service

Investing in Reliability at Milwaukee Medical Campus

Milwaukee Regional Medical Center Thermal (MRMC Thermal) provides steam and chilled water for heating, cooling, and critical process load for the hospitals and other buildings on the Milwaukee Regional Medical Center (MRMC) campus. MRMC acquired the thermal system in 2017, and Ever-Green played a critical role in completing an overhaul of the thermal system infrastructure, improving service reliability and reducing costs.

Infrastructure Investments

With leadership from Ever-Green Energy, MRMC Thermal made additional infrastructure investments that improved 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.

Ever-Green’s Role

Ever-Green provides system operations, maintenance, and management including business development, construction oversight, plant commissioning, system start-up, and water management services. Ever-Green is also developing a utility master plan for the MRMC campus, as it looks to double in size over the next several decades.

About MRMC

The campus is home to a Level 1 Adult Trauma Center at a nationally ranked academic medical center and a Level 1 Pediatric Trauma Center at Children’s Hospital of Wisconsin. The medical center member organizations provide continuum of care rehabilitation services and offer new discoveries and cures to patients throughout the world. Milwaukee Regional Medical Center members share a common mission of excellence in patient care, medical education, life-science research, and community service.
