Time-of-Use Rate (TOU)

An electricity rate that varies by time of day. Peak hours (e.g. afternoon and evening) cost more; off-peak (night, midday in some regions) cost less. Solar and batteries can help shift usage to cheaper periods.

Example

With TOU, running the dishwasher at 10 PM may cost half as much as at 6 PM.
