In August, members of the Barkley Project Group geothermal team joined the Acho Dene Koe First Nation in Fort Liard to advance the community’s geothermal project, an initiative designed to bring sustainable, local, clean energy to the region.

Geology was not kind to P.E.I. from the perspective of utilizing geothermal technology, said MacLeod. “There was a study done in 1983 that a fairly deep hole was drilled in Charlottetown just to try and quantify what geothermal uptake opportunity there was here,” she said.

The report, The Deep Heat Advantage: A techno-economic analysis of Enhanced Geothermal Systems in western and northwestern Canada, models the cost of EGS at four hypothetical test sites in Alberta, British Columbia, Saskatchewan, and the Northwest Territories. EGS could soon become a low-cost option for meeting Canada’s growing demand for clean, reliable power, with costs as low as 3–6¢/kWh.

Geothermal’s economics are improving rapidly as technological advances in the industry reduce costs. This is raising geothermal's profile as a reliable, round-the-clock power source for use in a range of applications from northern military bases and mines to the hundreds data centres expected in coming decades.

Canada should build on FORGE’s lessons to launch Project AURORA – the Arctic Underground Research Observatory for Resource Advancement. Project AURORA would consist of one or more Northern test sites that design and adapt next-generation geothermal tech for the Arctic’s challenging terrain.
