Understanding The Time-of-Use (TOU) Rates
Time-of-use (TOU) rates are a type of electricity pricing that varies depending on the time of day, reflecting the cost of generating and delivering electricity during those times.
These rates are typically designed to incentivize electricity consumption during periods of low demand (and therefore lower cost) and discourage consumption during peak demand periods when electricity can be more expensive to produce and distribute.
