What Ever-Green Energy does
Ever-Green Energy is a privately held district energy systems operator and management company headquartered in Saint Paul, Minnesota, operating as a subsidiary of the nonprofit utility District Energy St. Paul. Founded in 1998, the company plans, designs, develops, operates, and maintains centralized heating and cooling infrastructure for institutional clients including universities, hospitals, government facilities, and large mixed-use developments. As of 2024-2025, Ever-Green's operations span five U.S. states (California, Illinois, Minnesota, Ohio, Wisconsin) with additional projects in Michigan, Vermont, and Canada, managing or operating 11+ district energy businesses and serving 32 million+ square feet of customer building space.
The company's technical portfolio combines combined heat and power (CHP), biomass-fired generation, geothermal and networked geoexchange systems, aquifer thermal energy storage (ATES), low-temperature district heating, and waste heat recovery from wastewater and industrial sources. Notable technical firsts include the first urban ATES system in the United States (Longfellow Community Energy in Minneapolis), one of the largest networked geothermal systems in Minnesota (The Heights, a 112-acre Saint Paul redevelopment), and the 55 MW heat / 25 MW biomass-fired St. Paul Cogeneration plant, which supplies 153,300 MWh of renewable electricity annually to Xcel Energy while displacing 100,000 tons of carbon per year. The company's wholly owned subsidiary Environmental Wood Supply processes 250,000 tons of urban wood waste annually as fuel feedstock.
Ever-Green earns revenue through three primary streams: long-term managed services contracts to operate and maintain client-owned district energy systems (entered via competitive RFPs and direct enterprise sales), project-based consulting across feasibility, design, engineering, and construction management phases, and utility ownership through affiliate companies that charge recurring utility rates to end customers. Customers include University of Minnesota Twin Cities, Oberlin College, Illinois Institute of Technology, Milwaukee Regional Medical Center, Hennepin County, Mission Rock (San Francisco), and CoolCo (Cincinnati). The company does not publicly disclose pricing or revenue and is closely held under nonprofit parent District Energy St. Paul's governance.
