“Duluth has a proud history of addressing challenges while delivering innovation. The Steam Plant project provides an opportunity for both – addresses our challenge of an 85-year-old, coal-fired down-town heating system while incorporating flexible and renewable energy sources, such as biomass, to fuel this closed loop hot water system. The time is now, and we’re ready to get this done to benefit downtown while protecting our natural resources.”

– Emily Larson, Mayor, City of Duluth
