Your consumption in kilowatt hours (kWh) is noted along the bottom of the graph. Each horizontal bar in the graph represents the average daily amount of electricity you consumed in kWhs for each billing period. The number indicated along the right side of the graph tells you the total amount of electricity consumption in kWhs you used in that billing period.

8: Electricity

Electricity charges reflect the cost of the electricity that is purchased by Toronto Hydro on your behalf for usage in your home or business. Toronto Hydro does not charge a markup on this cost; it is paid directly to our suppliers. The pricing rates for electricity typically change in November each year. Your electricity consumption (kWh) is separated into four rates: on-peak (highest price), mid-peak (mid price), weekend off-peak and ultra-low overnight (lowest price). Note: If you've signed a contract with an electricity retailer, the company's name and phone number will also appear in this location.

13: Important message

Remember to check this message box each month for important information that might affect your bill.

14: Meter Reading Period

Your Meter Reading Period indicates the start and end date of when your electricity usage data (kWh) was captured for billing. A billing cycle ranges from approximately 27 to 33 calendar days. This means that your bill could reflect a period of electricity use that is longer than one month. You can tell the length of your billing cycle by reviewing the 'Number of Days' column on your past bill.

15: Read type

The Read Type indicates how your usage data (kWh) was gathered during your meter reading period. For the majority of customers, this will appear as "ACT," which indicates the reading is based on the actual kWh used. In some cases "EST" will appear, indicating the reading is based on the estimated number of kWh used.

16: kWh used

This value represents your total consumption (kWh) during your Meter Reading Period, and is used in calculating portions of the Delivery charges on your bill.

17: Loss factor adjustment

The Loss Factor Adjustment represents Toronto Hydro's powerlines to your home for consumption. This factor is applied to your kWh Used to calculate the Adjusted kWh Used value on your bill.

18: Adjusted kWh used

The adjusted kWh Used value represents your total consumption (kWh) after the Loss Factor Adjustment is applied. This value is used to calculate portions of Delivery and Regulatory charges on your bill. This value is necessary in calculating these charges to recoup the costs associated with the generation and transmission of the electricity that is 'lost' as it travels along Toronto Hydro's powerlines to your home for consumption.
