How Time-Of-Use Rates Work

Time-Of-Use (TOU) is part of a statewide initiative designed to keep the electric grid reliable so everyone will have power when they need it.

Unlike flat rates, TOU rates vary by the time of day the energy is used. With these new rates, your bill will be affected by both when you use electricity and how much you use. The majority of business customers have already transitioned to TOU rates, and the remainder will transition by January 1, 2015.

Time-Of-Use Rate Periods

There are now different TOU rates depending on the season and the time of day the energy is used. They more accurately reflect the costs of energy at the time it is used. With TOU rates, when you use electricity is as important as how much you use.

The greatest demand on the grid is during on-peak periods. If you can shift energy use to off-peak or mid-peak times, you help reduce strain on the grid.
