Idaho Time of Use Plan

Shift your power and shrink your costs with the Time-of-Use plan.

Want to lower your electricity bill? The optional Time-of-Use pricing plan gives you the chance to save by simply adjusting when you use energy at home.

Electricity costs more during Peak Hours—typically mid-morning, late afternoon, and evening—when lots of people are using power at the same time.

But during Off-Peak Hours, like late at night or early morning, demand is lower and rates are cheaper.

By choosing the Time-of-Use plan and shifting your energy use to off-peak hours, you can save money and help use the grid more efficiently, which supports reliability for everyone.

Worried about trying something new? Trying a new plan shouldn’t feel risky — that’s why we’ve built in a safety net. With Idaho Power’s Time-of-Use Trial, you can explore this pricing plan and test new energy management approaches for a full year with confidence. Time of Use Trial ensures you won’t pay more in energy charges on the Time-of-Use plan compared to the Standard plan during your first year.

Frequently Asked Questions

How much will I pay?

Your monthly bill on the Time-of-Use plan will vary based on your energy use during higher- and lower-priced periods. If you can shift more of your energy use to Off-Peak hours — when prices are lower — you may pay less than on the Standard pricing plan.

You can estimate your bill on the Time-of-Use plan compared with your current plan by visiting tools.idahopower.com/MyAccount/CompareRates or by logging in to My Account and navigating to: Payments & Billing , clicking Overview, selecting Compare Your Bills, and clicking Compare Rates near the top of the page.

Who is eligible for the Time-of-Use plan?

The Time-of-Use plan is available to Idaho residential customers.

Worried you won’t save money? Learn how Time-of-Use Trial works.

Trying a new plan shouldn’t feel risky. That’s why Idaho Power’s Time‑of‑Use plan includes a built‑in safety net: the Time‑of‑Use Trial. Beginning Jan. 1, 2026, you can explore this pricing option—and try out new energy‑saving habits—for a full year with complete confidence.

With Time-of-Use Trial, Idaho Power will evaluate your energy costs after you complete your first full year on the Time-of-Use plan. If your energy (kilowatt-hour [kWh]) charges are more than they would have been under the Standard plan, you will receive a bill credit for the difference — minus a $10 processing fee. For example, if your Time-of-Use energy charges were $40 higher than the Standard plan, you would receive a $30 credit. The credit will appear on the next bill after the first-year review.

Time-of-Use Trial is available only during your first year on the Time-of-Use plan and applies once per home. The full first year must be completed to be eligible. Afterwards, you will remain on the Time-of-Use plan unless you choose to switch to another pricing plan. Time-of-Use Trial is currently only available to Idaho residential customers on the optional Time-of-Use plan (Schedule 5).

Who would benefit from this plan?

You may save on the Time-of-Use plan if:

On average, you use more than 1,300 kWh or pay over $150 per month.
You don’t use much energy during the On-Peak and Mid-Peak hours, or you can shift some energy use to Off-Peak hours.

For example, if your home uses about 1,300 kWh a month, you could start saving by shifting just 5% of your On-Peak energy (around 15 kWh) to Off-Peak hours. The more you shift away from On-Peak hours, the more you’ll save. Here are some examples of actions you could take to shift or reduce your energy use during peak hours:

Shifting energy use from On-Peak hours to Off-Peak hours

Action	kWh Shifted (Standard Appliance)	kWh Shifted (High‑Efficiency [HE] Appliance)
Run the dishwasher (25 times per month)	30 kWh	25 kWh
Wash and dry clothes (20 loads per month)	70 kWh	50 kWh
Charging a mid-size EV (3 times per week)	150 kWh	same

Reducing energy use during Mid-Peak and On-Peak Hours

Action	kWh Reduced (Standard Appliance)	kWh Reduced (HE Appliance)
Adjust thermostat 2 degrees cooler (when heating) for electrically heated homes only	7–22 kWh	5–16 kWh
Adjust thermostat 2 degrees warmer (when cooling)	5–15 kWh	4–11 kWh
Close window shades on hot days to reduce cooling needs	10–30 kWh	8–20 kWh
Avoid using the oven for dinner (10 times per month)	20–25 kWh	15–20 kWh

These estimates use assumptions for home size, typical weather, appliance efficiency, and how often an average family uses appliances and energy. Your actual kWh totals will vary. HE appliances use less energy than standard appliances.

How to check if you have an HE appliance:

Look for the ENERGY STAR® label. This is the easiest indicator of HE.
Check the Energy Guide label. Most appliances have a yellow Energy Guide sticker showing estimated annual energy use and comparisons to similar models.
Review the Energy Factor (EF) or Seasonal Energy Efficiency Ratio (SEER) Rating. These ratings are for water heaters, air conditioners, or heat pumps. Higher numbers mean better efficiency.
Age of Appliance. Older appliances (10+ years) are usually less efficient than modern models. Newer models often include advances in technology for energy savings.
Smart Features. HE appliances often have smart sensors, eco modes, or load-sensing technologies.

Why Should I change my Energy Use Habits?

On the Time-of-Use plan, you may pay less for the energy you use. The Summer On-Peak energy price is four times higher than the Off-Peak energy price. You benefit by paying the lowest rate for energy when you shift your energy consumption from On-Peak hours to the Off-Peak hours — such as when you’re using your dishwasher, oven, or washing machine

Is there a way to see if I would benefit from this plan with my current energy habits?

You can estimate your bill on the Time-of-Use plan compared with your current plan with the Compare Rates function in My Account or by logging in to My Account and navigating to: Payments & Billing , clicking Overview, selecting Compare Your Bills, and clicking Compare Rates near the top of the page.

If I don’t like the Time-of-Use plan, how do I switch to a different plan?

You can switch off the optional Time-of-Use plan at any time. When you do, your service will return to the Standard plan.

If you leave the Time-of-Use plan, you will need to remain on your new plan for at least 12 months before re-enrolling in the Time-of-Use plan. To request a plan change, email or call our Customer Care Team at 208-388-2323 or 1-800-488-6151, outside the Treasure Valley, weekdays from 7:30 a.m. to 6:30 p.m., Mountain Time. Choose option 1 for residential, then option 2 for Billing.

Can I sign up for the Time-of-Use plan if I am participating in A/C Cool Credit?

You can participate in both A/C Cool Credit and the Time-of-Use plan. The A/C Cool Credit program begins June 15.
