We’re sorry you have this perception about our answer to Denis’ question. Here are some more details. When Hydro-Québec says that Rate DT saves our customers money, we are referring to the annual bill. In order to calculate the annual bill, we take into account the fact that part of the consumption is billed at a higher price than that of Rate D (that is, when temperatures are under -12 °C or -15 °C, depending on the region), and that customers must buy fuel.
However, if you are referring to the message about the customer’s electricity bills at Rate DT, which presents the gain in dollars in relation to the cost of electricity under Rate D, this calculation disregards the price of fuel. In addition, Rate DT is established so as to allow customers to pay lower prices than they would under Rate D at all times (summer, fall, winter and spring), except for winter periods during which temperatures fall under -12 °C or -15 °C, depending on the region. This means that throughout the year, customers save money in comparison with Rate D, but because of peak time consumption, savings go down during certain times of winter. Even if the cost of electricity under Rate DT is higher than under Rate D at these points, Rate DT remains globally advantageous on an annual basis for virtually all customers that subscribe to it.
If a Rate DT customer concludes that he or she hasn’t saved money, it is important to understand the reason why. Several factors are at play and, as the case may be, the customer can choose to take corrective measures or even to discontinue Rate DT. Here are some examples of factors that may cause a Rate DT customer not to save on electricity costs: • the home no longer has a dual-energy system, and the customer did not request a rate change; • the fuel component in the customer’s dual-energy system was not working during cold snaps; • the fuel tank is empty; • the switch is set to electricity or manual mode, which stops the system from switching to fuel mode during cold snaps; • the customer complements the heating with an electric device during cold snaps; • the customer uses large amounts of electricity during peak periods (under -12 °C or -15 °C); • the customer makes appropriate use of the dual-energy system, but it is a particularly harsh winter season.
You will find very clear explanations of how Rate DT works and the eligibility criteria on Hydro-Québec’s website. Of course, Rate DT customers are always welcome to contact our customer services at 1 888 385-7252. A representative will be happy to help them decide whether Rate DT is still the best option for them.
