The electricity rate hike granted by the energy board (Régie de l’énergie) is lower than what Hydro-Québec had requested. The decision makes a greater difference for commercial customers, while the Legault government has capped the residential rate increase at 3 per cent. Hydro-Québec had asked for annual increases of 4.8 per cent for businesses and institutions in 2026, 2027 and 2028. The board is instead granting 3.6 per cent each year, in a decision issued Monday. The gap is less notable for residential customers. Hydro-Québec requested 3 per cent each year, which it will receive in 2026 and 2027. The allowed increase for 2028 is 2.6 per cent. The owner of a three-bedroom apartment would pay an extra $2.30 a month, according to the board’s estimates — 10 cents lower than Hydro-Québec’s proposal. For the owner of an average-sized home (158 square metres), the monthly increase is $5.46, or 24 cents less than what the Crown corporation requested. Across the three years analyzed, the board estimates that the revenues Hydro-Québec needs to operate its network are $433.4 million lower than the Crown corporation’s own projections, out of a total of nearly $50 billion. Hydro-Québec is criticizing the decision, saying it would reduce its financial flexibility by nearly $450 million. The shortfall “will have a significant impact” on its investments aimed at improving reliability and energy efficiency, the Crown corporation says.
