Common questions

What are off-peak hours?

Off-peak hours are the hours when a time-of-use electricity plan charges its lowest price per kWh; peak hours are when it charges the most. They only matter on a time-of-use plan: on a flat or tiered plan (117 of the plans modeled here), every hour costs the same. On 13 of the 113 time-of-use plans modeled here, the summer weekday peak is 4 pm–9 pm.

Are weekends off-peak?

On 61 of the 113 time-of-use plans modeled here, Saturdays and Sundays have no peak or mid-peak hours in summer, so the whole weekend is off-peak. On the rest, the peak also applies on weekends; the Days column in the table says which.

Is electricity cheaper at night?

On a time-of-use plan, usually: 111 of the 113 plans modeled here include 2 am in their cheapest period. On 2, midday (1 pm) is cheaper than the night. On a flat or tiered plan the price is the same at night as during the day.

When are off-peak electricity hours?

It depends on your utility and plan. On 13 of the 113 time-of-use plans modeled here, the summer weekday peak is 4 pm–9 pm; 111 of the 113 plans include the overnight hours in their cheapest period. Outside the peak (and mid-peak) windows, the off-peak price applies.

What is the cheapest time to charge an electric car?

On most time-of-use plans, overnight. The table gives the cheapest summer weekday hours and price on each plan; the largest gap between the cheapest and the peak price is on Evergy Missouri Metro RTOU-3 (3.1¢ against 36.0¢ per kWh).

How do I find the cheapest hour for my appliance?

The best-time calculator finds the cheapest start hour for any load on your plan, and the EV calculator prices your car at the hour you plug in.
