Where am I ?


Your electricity meter keeps track of the number of kilowatt-hours of electricity you use. There are currently two types: digital Smart Meter and conventional dial meter.

Digital Meter How to read your digital meter

Reading a digital meter is easy. Simply read the meter like you would an odometer on a car — read the numbers from left to right.

NOTE: Your kWh reading will be displayed for four seconds followed by a one second display of ‘88888’. This will be continuous.

What is a kilowatt hour?

One kilowatt hour (kWh) is 1,000 watts of electricity used in one hour. That's equivalent to the power required to light a 100-watt light bulb for 10 hours, or to operate a standard 5,000 watt electric clothes dryer for approximately 12 minutes.


How to read your dial meter


How to read a dial meter 

Read the dials from right to left and write down the figures in the same order. Some of the pointers rotate clockwise, others counter-clockwise. Don’t worry about the very small dial. It’s a test dial to verify the correct reading of dial #1 – you don’t need to read or record it.

Please keep in mind the following important points so that your reading will be correct:

  • Some of the pointers rotate clockwise, others counter-clockwise.
  • When a dial pointer is between two numbers, read the smaller of the two.
  • When the dial pointer rests almost squarely on the number, as it does on Dial #4, the dial to the immediate right will determine which number you record.
Here's a sample reading:
  • Dial 1 – “5”
  • Dial 2 – “2” since the pointer is between 2 and 3
  • Dial 3 – “9” since the pointer is between 9 and 0
  • Dial 4 – “8” this pointer looks like it should be 9, but it is 8 because the pointer to the right has not completed a full revolution. If the pointer on dial # 3 had gone past 0, indicating the completion of a full revolution, the reading for Dial #4 would have been 9.
  • Using the example above, your reading would be 8,925.

What is a "Multiplier?

  • If your meter has four main dials, it records thousands of kilowatt hours. You'll see the words "MULT X 10" on the face of your meter — that means when you calculate your usage, you multiply the reading by 10.
  • If your meter has five main dials, it records tens of thousands of kilowatt hours, and you don't have to multiply.



Read your own meter (non-TOU billed customers)

By registering with our My Account website, you can send Hydro One your exact meter reading(s) so that it's reflected on your next bill. If you wish to provide a meter reading during an estimation month, please contact our Customer Communications Centre at 1-888-664-9376. You now have a longer window of opportunity to enter your reading(s) online, depending on your Bill Group and schedule. Simply log in to My Account, select "Submit Your Meter Reading" from the main menu and follow the on-screen instructions.

With the introduction of Time-of-Use prices, you’ll no longer have the need nor the ability to enter your meter readings online. You’ll be notified in advance of being switched to Time-of-Use prices directly through the mail with an education kit containing information on how to take advantage of Time-of-Use prices.

IMPORTANT: In the event that your digital smart meter stops communicating with the Automated Meter Reading (AMR) communications network (eg. signal is blocked by a tree or object, signal is out of range of a pole-top repeater, or signal is interrupted by severe weather conditions), the link to enter your own meter readings online will automatically re-appear on the My Account website. 

Your meter is reliable

Before installation, all electricity meters must meet strict accuracy requirements set by Measurement Canada. Once installed, meters are periodically checked by Hydro One Networks and government inspectors to ensure they continue to give accurate readings.

If you have questions or concerns regarding a high bill, log in to My Account and use the online tool to understand why.
