Electricity rates are set by the Régie de l’énergie, and are identical for all residential clients, no matter what part of Québec they are in. Rest assured that you and your sister pay the same rate.
The difference in your bills is due to a difference in your consumption habits: different appliances, the number of people living in the home, and the number of hot-water loads are all factors that can have an impact on your electricity consumption. Inadequate insulation and windows that are not energy-efficient can also drive up your bill significantly.
Once you’re aware of your electricity consumption habits and you adopt some simple yet efficient energy-saving measures, you can lower your bill considerably. We also encourage you to use our Dare to Compare function to compare your electricity usage with that of similar households.
