About

Technology firsts across the country:
• Ever-Green begins construction on the first commercial aquifer thermal energy storage (ATES) system in the US at The Heights, a Saint Paul Port Authority brownfield redevelopment.
• Ever-Green and Oberlin College complete installation of 850 geothermal wells and a steam to hot water conversion of a century-old system, keeping the campus on track to reach carbon neutrality by 2025.
• The team brings the black water recycling system online at the San Francisco Giants’ and Tishman Speyer redevelopment, Mission Rock with Ever-Green’s oversight. The system is designed to recycle 50,000 gallons per day for non-potable purposes in this gateway development in the Mission Bay neighborhood.

Caterpillar, Inc. and the Department of Energy team up for a three-year pilot program of testing the efficiency of hydrogen fuel in a 2 MWe generator hosted by District Energy St. Paul. This combined heat and power unit will harness waste heat from electricity production in the form of usable thermal energy for the district heating network.

Our team completes a major steam-to-hot-water conversion at Duluth Energy Systems in conjunction with a local road project and integration of the new regional medical developments. The project, comprised of 17 blocks, connects 31 buildings to hot water, and the modernization allows for natural gas to be added to the fuel mix. Greenhouse gas emissions have reduced by 50% per MWh sold from 2014 due to coal reduction and efficiency gains.

With documentation support from Ever-Green, Oberlin College is awarded $80 million dollars in Certified Climate bonds, enabling project funding while offering significant savings compared to traditional financing. This status certifies alignment with the goals and targets of the Paris Climate Agreement.

Our team eliminates coal as a fuel source at District Energy St. Paul, two years ahead of schedule.

In response to the growing demand for campus decarbonization support in higher education, Ever-Green launched our Roadmap to Carbon Neutrality offering pro bono services to University of Minnesota—Morris, University of St. Thomas, and the College of St. Benedict in 2019. In 2020, a second cohort included Macalester College and Slippery Rock University.

The Plume Project moves Ever-Green’s long-standing energy education efforts into community dialogue through a public art series. Our team has supported education, outreach, and engagement for campuses and communities across the country, applying our expertise in customer care, energy literacy, and communications.

Our collaboration begins at Milwaukee Regional Medical Center, a consortium of six health care institutions, including Level 1 Adult Trauma and Pediatric Trauma Centers. Ever-Green provides reliable service to health clinics, research labs, medical schools, and hospitals across our energy systems including 8 trauma centers providing lifesaving health care.

The Ever-Green team installs and begins operating the first solar thermal installation in the US to connect to a district energy system at District Energy St. Paul. This project is a collaboration between the City of Saint Paul, the Saint Paul RiverCentre, and District Energy St. Paul.

Our team installs 2.5-million- and 4.2-million-gallon thermal storage tanks to benefit customers with off-peak electricity rates and increased ability to meet higher customer demand at District Energy St. Paul.

Ever-Green develops St. Paul Cogeneration and Environmental Wood Supply, the biomass-fueled combined heat and power (CHP) and tree waste processing operations that provide renewable heat to District Energy St. Paul and renewable electricity to Xcel Energy.

Leaders at District Energy St. Paul establish Ever-Green Energy to advance systems beyond Saint Paul.
