EV charging
Compare the energy needed, then use the actual ULO or TOU schedule if that is your plan.

TOU, Tiered or Ultra-Low Overnight?
Ontario’s household price plans matter more than a low wholesale observation. Use the market signal as context, then check the OEB plan you actually pay.
Loading market data…
A charging-friendly night is not the whole annual bill.
The OEB lets eligible utility customers choose between TOU, ULO and Tiered pricing. ULO can suit flexible overnight EV charging, but your daytime use matters too. Use the OEB bill calculator to compare a whole household; CheapestHours does not evaluate these retail plans or automatically apply their prices.
Plan my use
Laundry / dishwasher
Check whether moving the cycle crosses a retail price band. The wholesale ranking is not an OEB off-peak calendar.
Compare my electricity use →Water heating
Enter the flexible kWh. The tool does not account for the rest of your household’s tier threshold or hydro bill.
Compare my electricity use →HOEP is no longer the current Ontario benchmark.
IESO’s Ontario Price has replaced the Hourly Ontario Energy Price (HOEP) under the renewed market. This page therefore describes the CA-ON data delivered by Elecz as a market signal without labeling it HOEP. Regulated Price Plan rates include Global Adjustment; they should not be replaced by the signal displayed here. The API view does not establish which IESO price series underlies every observation.

Before you run an appliance
Does CheapestHours apply my TOU or ULO rate?
No. The result uses the available Elecz market signal. It does not load your utility’s retail schedule or calculate an OEB plan comparison.
Is Ultra-Low Overnight always the best plan for an EV owner?
Not necessarily. The amount charged overnight and the rest of the household’s consumption both matter. Compare the full usage pattern with current OEB prices.
Do I add Global Adjustment separately to TOU prices?
Global Adjustment is already included in regulated TOU, ULO and Tiered electricity prices. Different arrangements can apply outside the Regulated Price Plan; check your utility’s bill explanation.
Are these times local to Ontario?
This page uses Toronto time with dates and seasonal clock changes. Confirm the clock and billing schedule used by your utility if your location follows a different time zone.
