Mitigating Winter Peak Demand

Electrifying residential space heating is central to Atlantic Canada’s path to net-zero—but this shift also intensifies winter electricity peaks, especially during the coldest hours of the year. Without targeted planning, these peaks could drive costly infrastructure investments that are rarely used. This study, jointly led by Net Zero Atlantic and the Institut de l’énergie Trottier, explores how residential space heating electrification and population growth will impact electricity system infrastructure requirements, GHG emissions, peak demand, and overall system costs in the region.

To reflect real-world system stress during extreme cold, the study uses the Atlantic Canada Energy System (ACES) Model, which accounts for temperature-dependent heat pump performance and the activation of fuel-based or electric backup heating systems. It evaluates one specific mitigation option: hybrid heating systems, where a heat pump serves as the primary long-term heating solution, supported by a supplementary fuel-based system that operates during periods of peak demand. This approach helps meet heating needs without compromising reliability and reduces the risk of costly infrastructure overbuilds.

The webinar will present key findings and highlight how region-specific modeling can support locally informed solutions that align with Atlantic Canada’s energy needs, infrastructure, and climate realities.

The event takes place at 1pm Atlantic time (12pm Eastern time).
