Feasibility Study - Collection & Utilization of Municipal Sourced Biomass (Yellowknife, Northwest Territories)

Stantec worked with the City of Yellowknife to assess its current solid waste collection system and characterize its waste streams to identify feasible solutions to reduce its dependence on fossil fuels to heat its buildings. If the project moves into design, it could reduce the loading on the solid waste facility by up to 7,844 tonnes of biomass material. This in turn could reduce the City’s diesel requirements by approximately 500,000 liters per year.

Working directly with the City, our Yellowknife office assessed potential buildings to include in the study and determined their annual heating loads. We also indicated the potential to utilize the heat in a municipal water heating application not previously considered. Using the annual heating loads, our team developed and costed a potential district heating network design to connect the buildings, as well as the water heating application.

In order to utilize the waste streams to service the heating loads, we presented the City with two potential material handling scenarios, and multiple options for sizing the biomass plants. The study investigated 14 options to utilize the biomass in both heating and cogeneration applications. Each option was costed and simple paybacks used to determine their financial viability. Rounding out the assessment, a sensitively analysis on the options was conducted, as well as an implementation plan developed to support the City’s decision on how to proceed with the project.

Northern Property REIT, WPB Installation (Yellowknife, Northwest Territories)

Stantec provided design and construction services for four wood pellet boiler installations. Each boiler services between two and four apartment buildings.
