About Your Meter

The switch to smart meters


If you’re an Alectra Utilities business customer in Mississauga who consumes a demand of less than 50 kW your hydro meter is probably a smart meter. A smart meter looks like an older hydro meter except the display is digital and there are no dials. You’ll find your smart meter outside along the wall or in the basement of your business.

If you’re a landlord in a building where tenant movement means you sometimes have to manage their meters, you can become a cut-in landlord.

If you run a condominium corporation, you can enable individual suite owners to monitor and manage their own electricity use and costs.

Smart meters help you conserve and manage energy by measuring your electricity use every hour and sending a reading of it to Alectra Utilities every day. This helps you track your electricity use.



Reading your smart meter

Your energy use

sm-image002A smart meter uses digital numbers to record your energy use. The number on this meter shows that a total of 10460 kilowatt hours (kWh) have been used.

The black square below the number blinks when energy is being used. The faster it blinks, the faster the consumption.

The arrow next to the square tells you which direction energy is flowing: pointing right, it means energy is flowing into your business.

Association numbers

sm-image003You’ll also see a number on the smart meter called an association number, like the example below. The association number identifies the neighbourhood collector meter — this is a central meter that gathers readings from several hundred properties in one area. The collector meter then sends all those readings to Alectra Utilities.


Error messages

sm-image004If you see a number on your smart meter starting with an ‘E’, like the example below, there might be a problem with the meter. If that happens, Mississauga residents can call Alectra Utilities Customer Service at 905-273-7425.


Test messages

sm-image005You sometimes might see everything on your smart meter light up with 8s. This is to test that the meter is working correctly. It has no effect on your energy reading. You should know that Alectra Utilities has a rigorous meter-testing program. All electricity meters must meet federal government regulations and may be checked by government inspectors to ensure readings are accurate.


How smart meters work

  • Your smart meter measures the energy you use every hour, and sends a reading of it to a collector meter, which sends it to Alectra Utilities every day using wireless communication.
  • Alectra Utilities then sends the information to a central storage facility that collects meter readings from homes and businesses across Ontario.
  • This information helps Ontario’s Independent Electricity System Operator (IESO) understand where electricity is being used.


If you still have a mechanical meter

A few of our customers may still use mechanical meters. You’ll find your meter along the outside wall or in the basement of your business. It’s in a grey metal box with a round, glass front that has four dials.

Sometimes we’re unable to read your meter — for example, if the meter is blocked or is in your basement and we can’t get in to view it. If that happens, our meter reader will leave a card at your business telling you that we could not get a reading. We then estimate the reading to bill your account.
