District heating: a practical solution for reducing fossil fuel dependency in Quebec’s remote communities

Abstract: Fossil fuel dependency is a significant barrier to economic growth and self-sufficiency in remote communities. While renewable electricity integration is a common approach to reducing this dependency, investigation of low-carbon heating alternatives is lacking. The present study proposes district heating as a practical pathway to achieving significant reductions in greenhouse gas emissions. A district heating network is designed in QGIS and a simulation model developed in TRNSYS for the community of Whapmagoostui-Kuujjuarapik, Quebec. Generator waste heat recovery, excess renewable electricity and a centralized oil-fired boiler are all considered as heat sources in the model. Simulation results are compared with HOMER-optimized scenarios of hybrid wind-diesel-battery systems revealing that there is a point where district heating becomes the more economically feasible option.
