Time of Use Shift


It has been a few years since the Smart Meters rolled out and Time of Use rates began for London Hydro users, so perhaps a refresher is in order!


TOU is the method used to calculate how much you will be charged for your electricity use. There are three different rates throughout the day and you will be charged a different rate for the time of the day in which you use it.


Every six months, the times of the day that different rates are charged will shift. During the winter months, the peak pricing is in the morning and evenings (when demand is highest for heating) and during the summer months it’s peak is in the afternoon (when air conditioner/cooling demand is highest). The shift happens May 1 and November 1 of each calendar year.


The current rates as of May 1, 2015 are as follows:

Off-Peak: 8.0c/kWh

Mid-Peak: 12.2c/kWh

On-Peak: 16.1c/kWh

Weekends and Statutory Holidays are all off-peak rates.


Here are some tips for keeping your hydro bill down during the warmer months:

  • hang your laundry outside to dry on sunny and/or breezy days
  • do your laundry on the weekends or evenings
  • run the dishwasher in the evening
  • turn your pool filter off during the day or the afternoon and run it at night whenever possible
  • close your blinds on sunny days to block the heat
  • use fans at night instead of turning up the a/c
  • open your windows on breezy days or when the humidity drops
  • make sure that all appliances, lights and chargers are turned off/unplugged when you leave the house for the day
  • use a programmable thermostat to keep the house cooler when you are home and not use the a/c as much when you are out
  • try not to use the oven when the a/c is on or on the hottest days; use the BBQ or smaller appliances like the toaster oven which won’t heat up your house
  • power off your laptops, computers, phones, tablets, etc. every night while you are sleeping
  • turn off your smart phones/tablets when they’re charging – they’ll charge faster! – and then unplug the charger when you’re done
