The free thermostat and energy display offer is now closed.

You and 35,000 Ottawa households are helping to reduce stress on our power grid when it is needed most – hot days in the summer.

Thank you for your ongoing participation!


How it works

  • A few times a summer, during times of peak electricity demand, your thermostat may be signalled to pause and release your central air conditioner in intervals of 18 minutes off and 12 minutes on, over a maximum of four hours.
  • Your furnace fan will continue to operate so you likely won’t notice a difference in temperature.
  • Activations only occur on weekdays between 12 p.m. and 7 p.m. from May 1st to September 30th. Activations never occur on weekends or statutory holidays.
  • You can opt out of an activation in advance by calling 1-866-813-2226.
