Time-of-Day Program

Participating in the optional Time-of-Day program may save you money—and help reduce peak demand on the electrical system. Southern Idaho’s summer months place the greatest demand on our electrical system. Many thousands of air conditioning units cooling homes and businesses throughout the valley coincides with the agricultural irrigation season, creating an ever-increasing need for power during the hot afternoon and evening hours. That’s why we’d like you to consider rethinking your energy use this summer and join our Time-of-Day program.

If everyone makes a small effort to be mindful of energy use during these high demand periods this summer, the entire community benefits from a more stable, reliable electric system.

Time-of-Day (weekdays only)	Summer Energy Time Periods	Rates*
1 p.m.–9 p.m.	On-Peak	8.9 cents per kWh
7 a.m.–1 p.m.	Mid-Peak	6.5 cents per kWh
9 p.m.–7 a.m.	Off-Peak	4.8 cents per kWh

This program requests that you monitor your energy use on weekdays only—weekend and holiday monitoring is not required on the Time-of-Day program. By shifting your heaviest electricity use to certain time blocks, you could realize energy cost savings. If you choose to use less energy during high-demand times of the day, you’ll help reduce the demand on the system, pay less for your electricity and possibly reduce your overall power bill.

For instance, if you can delay using your dishwasher, oven or washing machine until after 9 p.m. on weekdays, you will be placing less demand on the system and paying a lower rate for the electricity you use when running that dishwasher at another time. It helps balance the demand for electricity with the supply and may result in a lower power bill.

Why Should I Change My Energy Use Habits?
On the Time-of-Day program, you may pay less for the electricity you use. The off-peak rate is 4.8 cents per kWh, compared to the on-peak rate of 8.9 cents per kWh. For shifting your energy consumption from the daytime hours to the late evening hours, you are rewarded by paying the lowest rate for electricity.

Consider this example in which 10 kWh of electricity (about the amount of electricity consumed to run two loads of laundry) are used during the on- and mid-peak hours compared to during the off-peak hours.

If you use 10 kWh during:	You’ll Pay:	The Difference:
On-Peak Hours	10 kWh x 8.9 cents	85 percent more than during Off-Peak hours
Mid-Peak Hours	10 kWh x 6.5 cents	36 percent more than during Off-Peak hours
Off-Peak Hours	10 kWh x 4.8 cents
