The town of Sussex in New Brunswick has started exploring plans to convert an old Potash mine into a geothermal energy plant. An initial feasibility study done by Amec Foster Wheeler has been completed, but the project is still a few years away from being shovel ready. The plan would involve running an open-loop geothermal system inside the former mine to deliver heat energy to local community. There are a number of businesses interested in this project, including a Avon Valley Greenhouse. The 20-acre site could stand to save 70% on its heating costs if it switches away from wood to geothermal as a heating source. The initial price tag for the system currently stands at $11.3 million, with an anticipated payback period of 7 years.
