Rate Options

Residential and small business customers who are billed under the provincial Regulated Price Plan (RPP) can choose between Time-of-Use (TOU), Ultra-Low Overnight, or Tiered pricing for their electricity.

Residential and small business customers who choose to be billed under the Time-of-Use (TOU) pricing structure pay different rates for electricity consumed during different times of the day. There are three TOU periods:

  • on-peak
  • mid-peak
  • off-peak

Prices are highest during on-peak, lower during mid-peak, and lowest during off-peak. TOU prices encourage households and small businesses to use electricity during lower-cost time periods (ex. running your dishwasher and doing laundry at night).

TOU prices are set to be cheapest when demand is lower: during the evenings, on weekends, and on holidays. TOU price periods are different in the summer than they are in the winter.

Summer 2024 Time of Use Rates

Residential and small business customers who choose to be billed under the tiered pricing structure pay a set rate for the electricity they consume up to a kilowatt-hour (kWh) threshold per month. Customers that exceed this monthly threshold are billed at a higher rate per kWh for all additional electricity consumed.

Tiered prices give you the flexibility to use electricity at any time of day at the same price, although that price will change if you exceed the threshold during the month.

Tiered Rates and Thresholds

For residential customers, the threshold changes with the season to reflect changing usage patterns. 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 a lower price. In the summer period (May 1 – October 31), the Tier threshold for residential customers is 600 kWh.

Tiered Rates Effective November 1, 2023

With Ultra-Low Overnight (ULO) pricing, the price depends on when you use electricity. You can help manage your electricity costs by shifting your usage to lower price periods when possible. There are four price periods:

  • Ultra-Low Overnight: When demand for electricity is lowest on average
  • Weekend Off-peak: When demand for electricity is generally lower
  • Mid-peak: When demand for electricity is moderate
  • On-peak: When demand for electricity is highest on average

With ULO, the price periods remain the same all year round.

Frequently Asked Questions

Under Time-of-Use and Ultra-Low Overnight pricing, the price you pay for electricity depends on when you use it. Under Tiered pricing, you can use a certain amount of electricity each month at a lower price, and once that limit is exceeded, a higher price applies.

For more information on Time-of-Use, Ultra-Low Overnight, and Tiered Pricing, as well as tools to help you decide which price plan is right for you, please visit www.oeb.ca/choice.

Residential and small business customers that have smart meters and are billed under the Ontario Energy Board’s Regulated Price Plan (RPP) are eligible to choose between TOU, ULO, and Tiered pricing.

Power is personal! When choosing a price plan, it’s important to know what your overall electricity consumption is and how your lifestyle can influence your energy costs. Below are a few things you should consider.

  • Your price plan – Do you currently pay TOU or tiered prices for your electricity?
  • Your consumption pattern and usage – When do you use electricity and how much electricity do you use in a month?
  • Your lifestyle and daily habits – Are you often home during the day on weekdays, so that shifting your usage is more challenging? Do you have large appliances that you need to run during the day on weekdays? Can you shift more of that usage to nighttime or weekend hours?
  • Calculate and Compare – Don’t guess. Use the Ontario Energy Board’s bill calculator to compare the different price plans and choose the option that best suits your consumption habits and lifestyle.

You can visit the Ontario Energy Board’s (OEB) website for more information on TOU, ULO, and Tiered pricing, as well as compare rate plans using the OEB Bill Calculator.
