Carleton Constructs Geothermal Well Fields
22 August 2017Carleton College launched construction on a new utility master plan, beginning with the installation of two geothermal well fields this summer, in anticipation of replacing its current steam plant with a transition to a low temperature hot water system.
“By transitioning to a system that requires far less heat input, we will have the flexibility to use a much more diverse portfolio of energy sources, including renewable energy technologies of today and the future,” states Martha Larson, manager of campus energy and sustainability.
Carleton is the first college campus in Minnesota to have a geothermal-based district energy system, and one of only three in the entire Midwest to host a campus–scale geothermal project.
