In the Northwest Territories there are numerous opportunities for waste heat recovery given the significant number of communities with diesel generated electricity. 25 of the 33 communities in the NWT have diesel-generated electricity. You can see how power is supplied to each community in the NWT using the following map: https://ntpc.com/our-community/community-map . The diesel electricity systems are not very efficient, with ~ 2/3 of the diesel fuel burned that is lost as waste heat, so pursuing waste heat recovery would have a significant impact on community greenhouse gas emissions.
Fort Liard & Fort McPherson have had waste heat recovery systems set up by the Northwest Territories Power Corp. (NTPC): https://ntpc.com/smart-energy/how-to-save-energy/residual-heat-recovery In addition, the Snowshoe Inn (Fort Providence) also has a waste heat recovery system in place that provides heat for the main hotel building plus the restaurant and Snowshoe Centre across the road.
Location of the generators is one of the determining factors for consideration of waste heat recovery as is the cost to set it up. Fortunately, NTPC has been interested & willing to set it up for the communities of Ft. Liard & Ft. McPherson.
There are likely also significant opportunities in the industrial sector as well, given the off-grid set-up for a number of large, mining operations. I am just not aware of what those exact opportunities are.
