Heating buildings with electricity puts significant pressure on Hydro-Québec’s network during the winter consumption peaks. Dual energy is an excellent way to maximize the share of electricity in building heating while reducing the impact on peaks. Reducing electricity demand at these specific times optimizes the operation of the grid when it is most needed. This allows Hydro-Québec to avoid additional investments or expenses to meet demand during peak periods.
Over the 2022–2030 period, the dual-energy offer will therefore allow Quebec society to save nearly $1.7 billion compared to an all-electric scenario, which would have a much greater rate impact.
