What are SCE Time-Of-Use (TOU) Rates?

SCE TOU rates represent a departure from traditional billing methods by introducing dynamic pricing based on the time of day.

Under TOU rates, prices vary depending on when electricity is consumed, with rates typically divided into peak, off-peak, and shoulder periods.

Peak hours, when energy demand is highest, incur higher rates, while off-peak hours, characterized by lower demand, offer cheaper electricity.

The primary purpose of SCE TOU rates is to incentivize customers to shift their energy usage away from peak periods, thereby reducing strain on the grid and promoting more efficient energy consumption practices.

Unlike traditional flat-rate billing, where consumers pay a fixed price per unit of electricity regardless of when it is used, TOU rates offer a more nuanced approach to pricing. Flat-rate billing fails to account for the varying costs associated with generating electricity at different times of the day, resulting in inefficiencies and higher overall costs.

In contrast, TOU rates encourage consumers to adapt their behavior by providing financial incentives to consume electricity during off-peak hours, when it is cheaper to produce.

By aligning energy usage with periods of lower demand, customers can potentially lower their electricity bills while also contributing to a more stable and sustainable energy grid.
