How Peak Perks works

Participants in Peak Perks save with their smart thermostats by participating in brief, time-limited thermostat adjustments during periods of peak electricity demand that can occur on the hottest summer days.

  • Peak Perks events will occur only on weekdays for up to three hours during periods of peak demand for electricity. Events will not take place on weekends or holidays.
  • Events can occur up to 10 times between June and September.
  • During an event, your thermostat will be automatically adjusted no more than two degrees Celsius to reduce your home’s energy consumption.
  • Prior to an event, your thermostat may be adjusted down slightly to pre-cool your home so that you remain comfortable while an event is taking place.
  • You are always in control – you will be notified when an event occurs and can opt out at any time during an event from your thermostat provider’s mobile app, or by simply adjusting your smart thermostat back to your desired comfort level.
  • Once an event ends, your thermostat will return to its original temperature setting.
