Hydro-Qu Quebec dual energy

A dual-energy home heating utilizes two energy resources: electricity and gas, usually oil.

The gasoline is used as an auxiliary energy source of temperature as opposed to electricity when it's really cool, that will be as soon as the Hydro-Québec energy grid is in biggest force.

But whom benefits from dual power, clients or Hydro-Québec?

Twin energy sources are really good for domestic customers withn’t got dual-energy home heating systems, people who have all of them therefore gain much more, and Hydro-Québec it self.

A dual-energy home heating lowers the interest in power in top periods, which are generally winter cool spells. This provides Hydro-Québec some freedom in regards to the quantity of electrical energy it offers available to fulfill Québec customer’s greatest need for power at those times and makes it much simpler to balance large electricity demand with accessibility.

Customers with dual-energy heating systems have the extra advantage of speed DT, that will be general less expensive for all of them.

Do you know the special attributes of speed DT?

This price features two prices that apply at different conditions. As soon as the outside heat is more than or corresponding to -12°C or -15°C (based your location), the heat runs on electrical energy therefore the lower price relates to electrical energy used. Once the outside heat goes below -12°C or -15°C (dependent on in your geographical area), your home heating immediately switches from electrical energy to fuel. The electrical energy you utilize then is billed within higher associated with two Rate DT costs. Warming with gasoline is more cost-effective than, particularly because heating is a household’s primary utilization of electricity. And indicator light goes on as soon as the system is running on gasoline and goes off with regards to switches to electrical energy.

Most often used warming methods that be eligible for rate DT

  • Dual-energy forced-air methods of next types:
  • Dual-energy forced-air system coupled with a central temperature pump
  • Fuel-burning forced-air system coupled with a main temperature pump
  • Fuel-burning forced-air system combined with electric heating elements
  • Dual-energy forced-air (with radiators, as an example), combining a fuel-burning boiler and electric boiler (boilers tend to be called furnaces)
  • Exactly how a dual-energy system entitled to Rate DT works

    Numerous elements have to make a dual-energy heating system qualified to receive speed DT. It must immediately switch from origin to another when it obtains a signal from the outdoor-temperature sensor, frequently included in Hydro-Québec’s meter. An indicator light continues on as soon as the home heating is operating on gasoline and converts off with regards to’s using electricity.

    Dual-energy system

    1. Higher-price indicator light

      This light, installed in your house, preferably in basic view, shall help you handle your use of electrical energy better.

      It explains which kind of energy is being used for home heating therefore which price applies.

      Once the light is off, the heating system is operating on electricity and you'll be billed during the cheap.

      If it is on, the heating system is operating on fuel, because the outside heat is below -12°C or -15°C, whilst the case is. You're going to be billed within greater cost.

    2. Dual-energy meter

      The dual-energy system calls for an unique meter that records electrical energy usage at the two various rates.

      There are two lights on the meter housing:

    3. The green light shows that switch is working. It must always be on.
    4. The red light shows that the outdoor heat is underneath the important limit of -12°C or -15°C (and that means you will be billed on higher price).
    5. Heat sensor

      The outdoor sensor delivers a signal to the heat if the heat drops below –12°C or –15°C (according to your weather zone).

    6. Mode choice switch

      Manual switch you can make use of to choose whether your heating system works on gas, double power or electrical energy.

      To just take features of speed DT, you'll want to set the mode selection switch to dual energy. According to the outdoor heat, the device automatically switches from electrical energy to gasoline or vice-versa, whichever is much more economical.

    7. Most commonly used heating methods that be eligible for speed DT:
    8. Dual-energy forced-air methods associated with following kinds:
    9. A dual-energy forced-air system, a fuel-burning system with integral electric home heating elements
    10. Dual-energy hot-water system (with radiators, for instance), incorporating a fuel-burning boiler and a power boiler (boilers are often called furnaces).

    Speed DT = Savings

    Rate DT is a superb package, except in exceptionally cold wather, if the temperature is below -12°C or -15°C, with regards to the area. But we have only those severe cold spells a few days annually, therefore Rate DT is overall cheaper.

    Comparison of domestic prices D and DT

    Price D
    Energy ingested to 30 kWh times the sheer number of times into the consumption period: 5.71¢/kWh Temperature above or corresponding to −12°C or −15°C (based on region): 4.60¢/kWh
    Staying energy/day: 8.68¢/kWh Heat below -12°C or -15°C (depending on area): 26.91¢/kWh

    With a compliant dual-energy heat put in

    In any case, one other appropriate costs apply, for instance the fixed fee of 40.64¢/day and the charge for demand exceeding 50 kW.

    Understand this contrast of typical energy charges for a 158-m2 (about 1, 700-sq. ft.) single-family house or apartment with four occupants in Montréal.

    Energy cost Complete
    Rate D Electrical Energy: $1, 995 $1, 995

    Yearly cost savings:

    Estimated cost of oil: $0.73/L.

    Net savings of approximately $294 if annual system maintenance expenses apply.

    Typical power costs

    Annual consumption for heating and hot-water, also basic uses.

    Calculating savings at Speed DT

    Annual consumption of 24, 987 kWh.

    Electricity – Rate D: 5.71¢/kWh for 10, 847 kWh (first tier) and 8.68¢/kWh for 14, 140 kWh (2nd level).

    Dual-energy – speed DT: 4.60¢/kWh for 21, 869 kWh if the heat is above or corresponding to –12°C or –15°C, 26.91¢/kWh for 831 kWh as soon as the heat is below –12°C or –15°C, and around cost of $0.73/L for 283L of oil.
