  Every degree makes a difference

  • Remember, adjusting your thermostat even
    slightly will count towards reducing your heating
    and cooling costs year-round.
  • In the summer, set your central air conditioner to 25 degrees C when you're away.
  • In the winter, set your thermostat to 20 degrees C when you're home and 18^ C when sleeping or away.


   A small change you can feel good about
   peaksaver PLUS® helps ease the strain on
   Ontario's electricity grid. Here's how it works:

  • On hot summer days when electricity demand is highest, peaksaver PLUS® signals your thermostat to slightly reduce your central air conditioner's energy demand so that it safely uses less electricity.
  • During such rare occasions your air
    conditioner's fan will continue to circulate the cool air inside your home, helping you to stay comfortable.
