Smart Meters Will Help Ontario Meet Its Energy Needs

Between now and 2025, Ontario must build almost a whole new electricity system. This includes replacing about 80 per cent of our current generating facilities as they retire over time, and expanding the system to meet our future growth.

Building new supply is vital. So is conservation. Conservation will help us to make the best use of our existing electricity resources and slow the growth in our demand. That's why Ontario is introducing new tools - like Smart Meters - that can help. Smart Meters will encourage us all to think more about how and when we use electricity.

Smart Meters will help smooth peak demand. When we're all using a lot of electricity at the same time we create a "peak demand" period. Supplying electricity at those peak times has a range of impacts:

  • They add to our electricity costs because higher demand often means higher market prices.
  • They're hard on the environment because more of the less attractive forms of generation must be run to meet them.
  • They add to the amount Ontario needs to invest in the system because meeting the peaks requires even more new generation, and more transmission and distribution infrastructure.
So, working together to reduce our use at peak times makes good sense.

Program to Begin in Whitby in December 2011

The Smart meters have been installed throughout Whitby and billing Time-of-Use rates is scheduled to begin December 2011. For TOU price buckets please see attached insert.

Tell Me More About Smart Meters


A Smart Meter is a huge advance over Ontario's current devices.
Our old-style meters can only measure the total amount of electricity used over an entire billing period because they have to be read manually. That's why, between actual readings, you might get an estimated bill that will be "trued up" at a later date.

A Smart Meter can automatically record when electricity is used.
That's what makes a Smart Meter so different. In the future, your Smart Meter will record your total electricity consumption hour by hour. And it will send that information to your utility through either a wireless or another form of technology.

Smart Meters make time-of-use (TOU) prices possible.
With the ability to measure when electricity is used, different prices can apply at different times of the day. With time-of-use pricing, you will have a new way to manage your electricity use and your bills.
