Your Electricity, Your Choice

As an Oshawa Power customer on the Regulated Pricing Plan (RPP), you have the option to choose between Time-of-Use (TOU) and Tiered pricing plans. You are free to change from the TOU pricing plan to the Tiered pricing plan, and back again, as you choose. Coming soon, customers will also have the option of a third pricing plan; the Ultra-Low Overnight (ULO) pricing plan.

Whether you just want to switch for a season, or test if a different plan works better for your lifestyle, the choice is now yours.

When Will I See the Change?

If you choose to change your pricing plan, your account will not be billed on your new rate plan until the beginning of your next billing cycle.

You will continue to be billed according to your current pricing plan until the end of your current billing cycle.

Choosing Made Easy: Rate Plan Estimator

To help you determine which pricing plan is the best fit for your lifestyle, we’ve launched our Rate Plan Estimator tool through MyOshawaPower.

About Time-of-Use (TOU) Rates

Under Time-of-Use (TOU) pricing, customers are charged according to the day of the week and time of day that they use electricity. This gives customers the option to shift higher electricity-use activities — such as laundry or running the dishwasher — to off-peak periods, which are charged at a lower rate.

There are three different TOU price periods: on-peak, mid-peak and off-peak.

TOU rates and price periods typically change twice a year (May 1 and November 1). Both the rates and price periods are set by the Ontario Energy Board (OEB).

May 1st, 2023 Time of Use Rates:

Off-Peak: ¢7.4/kWh
Mid-Peak: ¢10.2/kWh
On-Peak: ¢15.1/kWh

About Tiered Rates

Tiered pricing separates electricity consumption into two price tiers. Customers are charged one rate for electricity usage up to a certain amount of consumption (or threshold) per month, and a higher rate for electricity used above that amount.

The price threshold (the amount of electricity consumption that is charged at the lower price) is set by the Ontario Energy Board (OEB) and will typically change twice a year for residential customers.

Note: Updated Tiered rates as of May 1, 2023.

Tiered rates pricing – per 30 days (residential customers)

Price tier Description Price
Tier 1 Up to 600 kWh/month ¢8.7/kWh
Tier 2 More than 600 kWh/month ¢10.3/kWh

Tiered rates pricing – per 30 days (non-residential customers)

Price tier Description Price
Tier 1 Up to 750 kWh/month ¢8.7/kWh
Tier 2 More than 750 kWh/month ¢10.3/kWh

Coming Soon: ULO Rates

Ultra-Low Overnight (ULO) rates are structured similarly to TOU rates, with an additional pricing period and different rates. This plan is intended to encourage customers to shift their electricity to periods of lowest demand by offering the lowest possible electricity prices during the overnight hours of 11 p.m. until 7 a.m.

While this plan is unlikely to be the ideal choice for many customers, if you are able to reliably shift your consumption to this timeframe, it could lead to big savings. This may also be a good choice for electric vehicle (EV) owners who consistently charge up their vehicles overnight.

Actual pricing for ULO periods is not yet available from the Ontario Energy Board. We will update our website and notify customers via social media when pricing becomes available.

Actual ULO rate period pricing is still TBD.

+1. Who is eligible to switch?

Customers on the Regulated Price Plan (RPP) are eligible to switch. You can request to change your price plan option if: You’re a residential customer (including individually billed suites in a multi-unit complex) or a small commercial customer with peak demand less than 50 kW. You purchase electricity from Oshawa Power and don’t have a contract with an electricity retailer.

+2. Which plan is right for me?

Only you can decide which price plan is right for your household or business, since only you know how you plan to use electricity in the future. Some of the factors to consider when deciding which plan may be right for you include:
For residential customers:
How much time do you spend at home?
During what time of the day are you typically at home?
Is it convenient for you to perform higher electricity-use activities — such as laundry and running the dishwasher — during the evening and on weekends?
For business customers:
How many hours does your business operate?
When does your business need electricity the most?

+3. How do I switch my price plan?

Customers can switch their price plan by completing our online form

+4. If I make the change, when will I see it reflected on my bill?

If your form is received at least 10 calendar days before the beginning of your next billing period, then the change will take effect as of your next billing period.
If your form is received less than 10 calendar days before the start of your next billing period, then the change may not take effect until the second billing period after your form has been received.
Note: In either case, the earliest that the change will take effect is as of your first billing period after November 1, 2020.

+5. What happens if I do nothing?

Customers who don’t complete a form will remain on the TOU price plan and there will be no change to the way their electricity use is billed. Please note that the Ontario Energy Board announces new TOU rates effective May 1 and November 1 each year.
Customers don’t have to complete a form if they wish to remain on TOU pricing.

+6. Do I have to make a decision before November 1?

No. Customers are eligible to begin opting out of the TOU price plan effective November 1, 2020, but there is currently no deadline for opting out. Customers can choose to make the change at a later date or remain on the TOU price plan.

+7. Can I switch back to TOU Pricing once I have switched to Tiered Pricing?

Currently, customers who switch to Tiered rates will be permitted to switch back to TOU if they so choose. Please note that changes will not be reflected until the next billing period, and if the change is made less than 10 days before the start of your next billing period, then the change may not take effect until the second billing period after your change has been received.

+8. How do I know if my price plan has been changed?

Once we receive your request, we will notify you by letter within 10 business days regarding:
– When your chosen price plan will take effect; or
– Why we could not process your request
If you look at the electricity line on your bill, you’ll either see it broken down into TOU rates (off-peak, mid-peak, on-peak) or Tiered rates. If it’s not showing the option you selected, then your pricing plan hasn’t been changed yet.

Note: Please allow up to 10 business days for the switch to be processed. Please also keep in mind that the change won’t take effect until your following billing period.

+9. I’m a customer with a retailer contract. Can I switch?

Customers who have signed a retailer contract aren’t eligible to switch their price plan. If you would like to switch to a Regulated Price Plan option, you would need to cancel your current retailer contract and apply for the price plan of your choice. Please note that regardless of which plan you select, your first bill will be charged on the TOU price plan.
