Electricity meters are installed by Waterloo North Hydro Inc. to measure electrical usage. Here are some answers to common questions about meters.

How is electricity usage measured?

Electricity use is measured in kilowatt-hours (kWh). A 100-Watt light bulb left on for 10 hours will use 1 kWh.

Does my meter have to be accessible?

How do I read my meter?

Your meter is an electronic Time-of-use (TOU) meter. In normal operation it will cycle through the displays as indicated in the illustration below.

  • LSt003 - Indicates the next display records kWh forward direction (kWh Delivered).
  • kWh Delivered - This mode displays total kWh consumption. To determine how much electricity you use in a day for example, simply read the six digit number at about the same time each day and subtract yesterday's reading from today's reading.
  • LSt053 - Indicates the next display will show a snapshot of the current being used at this location.
  • Instantaneous Current - For example, instantaneous current is 12.03 Amps. (Present Load = 12.03A x 240V = 2.89 kVA).
  • Display Check - The display shows six number eights. This display verifies that the entire system is functioning properly. This screen is for Waterloo North Hydro use only.
