A tool you can count on to save

  • A properly set thermostat can mean using less energy.

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 degrees 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.

You will never be affected on weekends or statutory holidays

Typically, peaksaver PLUS® is activated:

  • From May 1 to September 30
  • Only on weekdays (Monday to Friday)
  • Between 1 p.m. and 6 p.m., but never for more than four hours.

If you would like to opt out for a specific day, simply call 1-866-380-6051 in advance.
