TOU seeks to encourage Customers to shift their Electricity usage to times of lower demand.
- Tiered Tariffs/Rates: Units of pricing that vary for different levels of Energy consumption.

- Fixed Charges: Flat fees paid regardless of the actual volume of Energy consumed and/or level of instantaneous Power required. Fixed charges are typically designed to cover the costs associated with maintaining the Electricity infrastructure where volumetric tariffs/rates are not able to equitably apportion these costs.
- Demand Charges: In addition to volumetric consumption of Energy, demand charges reflect the Customer’s highest level of instantaneous Power required over a specific period.
