A northern Maine hospital has a new biomass boiler that will offset the need for 100,000 gallons of heating oil per year. An open house to show off the new boiler at Northern Maine Medical Center in Fort Kent is scheduled for Monday. The new boiler utilizing local trees and other dead vegetation will help the hospital to lower heating bills, improve energy efficiency, and reduce dependence on foreign oil. It replaces three outdated boilers and is expected to save the hospital $200,000 annually in operating costs. The biomass boiler was funded through a U.S. Department of Agriculture guaranteed loan of $6.7 million in partnership with Katahdin Trust.
