Understanding your electricity bill


Kingston Hydro electricity customers receive their bill through Utilities Kingston. Most benefit from the convenience of one combined bill for all their utility services, which may also include water, wastewater, and gas. A combined bill helps lower costs for all rate payers.

Electricity rate plans: it's your choice!

If you’re a residential or small business customer who pays Time-of-Use electricity prices, you can choose to switch to Tiered prices.

With Time-of-Use, the price you pay depends on when you use electricity. With Tiered prices, you can use a certain amount of electricity each month at a lower price. Once that limit is exceeded, a higher price applies. 

If you want to continue paying Time-of-Use prices, no action is required. Utilities Kingston's electricity customers, who would like to switch to Tiered prices, can use our election form.

For more information on Time-of-Use and Tiered Pricing and tools to help you decide which price structure is right for you, please visit

The Time-of-Use and Tiered prices apply to the electricity commodity portion of their bill.

Time-of-Use price plan

With Time-of-Use pricing,  customers are charged less at times when the demand is lowest: during the evenings, on weekends and on holidays. For example, you’ll save money by doing your laundry on weekends or later in the evening.

People use electricity differently depending on the season, so the Ontario Energy Board established two sets of time-of-use rate periods: summer and winter. No matter which season, on weekends and holidays the cheapest rates are in effect all day. 

Tiered price plan

With Tiered prices, you can use a certain amount of electricity each month at a lower price. Once that limit (called a threshold) is exceeded, a higher price applies.

In the winter period (November 1 – April 30), the Tier threshold for residential customers is 1,000 kWh, so that households can use more power at the lower price. In the summer period (May 1 – October 31), the Tier threshold for residential customers is 600 kWh. The Tier threshold for small business customers is 750 kWh all year round.

Glossary of terms

The Kingston Hydro website provides definitions of energy terms that are found on the electricity bill for low volume electric customers.

Energy retailers

If you have a contract with an energy retailer or are thinking about signing with one, your bill will look a little different than customers billed on TOU pricing. A customer signed with a retailer is charged the contract price for the electricity commodity portion of your bill and also a global adjustment charge.

If you are approached to sign or renew a gas or electricity contract for your home or small business, it is important to know who you are dealing with. Energy company salespeople must wear an ID badge and give you a business card. See the OEB web site for four things to remember if you are approached to sign an energy contract.

Additionally, in order to provide low volume consumers with information regarding their retail energy options, the OEB provides lists of active licensees that market gas or retail electricity to low volume consumers.

Smart meters and time-of-use (TOU)

All our residential customers have smart meters to automatically record electricity consumption on an hourly basis. This helps consumers take advantage of TOU pricing.

For more details, visit Smart meters, at the OEB web site.

Ontario Clean Energy Benefit

Your bill. Your grid.

Your electricity bill includes the costs for the electricity that you use, the services your local utility provides and some other costs as outlined at the link below.

The total amount on your energy bill comes from four costs, of which only a portion is retained by your local utility. Visit Ontario Energy Board's "Understanding your electricity bill"  to learn more.

Ontario Electricity Rebate

On November 1, 2019, the Ontario Electricity Rebate (OER) was applied to bills for most residential consumers, farms, and many small businesses. 

As of July 1, 2022, the Ontario Electricity Rebate provides a 17 per cent rebate on electricity charges for eligible customers, and appears on your electricity bill as a single line item.
