In parallel to the Biosolids Strategy, the Region started a feasibility study to look at opportunities for fully utilizing this renewable gas. This aligned with a number of Regional priorities including the Corporate Energy Plan, Sustainability Strategy and Strategic Plan. In addition, with electricity prices increasing, the Region was also interested in looking for opportunities to make operating costs more sustainable, says Law. The solution came in the form of cogeneration facilities at the region’s three largest WWTPs, Kitchener, Waterloo, and Galt. “The operation of these engines allows us to meet the heating needs for our treatment processes as well as heating for our administration facilities,” says Law. “The operation of the engines also generates electricity and allows the Region to significantly displace the amount of electricity purchased from the grid.” At the beginning of the process, the Region reached out to other municipalities that had recently implemented similar technologies, such as Chatham-Kent, the City of Toronto and the Region of Peel. “It is great to learn from experiences of other municipalities on all aspects of the process from approvals to design to operation,” says Law. 79 APR 2023 | BUSINESS ELITE CANADA
