On the current APS Time-of-Use 4pm-7pm Weekdays plan, electricity is on-peak only from 4pm to 7pm on non-holiday weekdays. Weekends, designated holidays, and every other hour are off-peak. A separate super-off-peak period applies from 10am to 3pm on qualifying winter weekdays.
This page was rebuilt from the official APS TOU-E tariff, the current plan overview, and APS's holiday guidance. It covers TOU-E, not every APS plan. Check the plan name on your bill before using the schedule.
Will this day have peak hours?
For APS Time-of-Use 4pm–7pm Weekdays (TOU-E), without a demand charge. Check your plan name first. This covers the standard schedule, not other plans or special pricing events.
All times are Arizona MST. Schedule checked September 4, 2026 against the APS TOU-E tariff, effective March 8, 2024, and current plan guidance linked below. This does not estimate savings. Keep essential cooling and medical equipment operating as needed. We count completed checks; your date and billing-season selection are not sent to analytics.
Current TOU-E time windows and prices
| Billing season | On-peak | Off-peak | Super off-peak |
|---|---|---|---|
| May-October | 4-7pm weekdays 34.396¢/kWh | All other hours 12.345¢/kWh | None in summer |
| November-April | 4-7pm weekdays 32.543¢/kWh | All other hours 12.351¢/kWh | 10am-3pm weekdays 3.495¢/kWh |
These are the tariff's bundled energy charges. APS bills can also include a basic service charge, adjustors, taxes, fees, and solar-specific charges. Use the APS bill calculator to model the base energy portion without pretending it is your complete bill.
APS off-peak holidays in 2026
The dates below are off-peak all day for TOU-E. When a fixed-date holiday falls on Saturday, APS observes the preceding Friday as off-peak; when it falls on Sunday, APS observes the following Monday. Christmas Eve and New Year's Eve count only when they fall on a weekday. Both do in 2026.
| Holiday | 2026 date | TOU-E treatment |
|---|---|---|
| New Year’s Day | Thursday, January 1, 2026 | All day |
| Martin Luther King Jr. Day | Monday, January 19, 2026 | All day |
| Presidents Day | Monday, February 16, 2026 | All day |
| Cesar Chavez Day | Tuesday, March 31, 2026 | All day |
| Memorial Day | Monday, May 25, 2026 | All day |
| Juneteenth | Friday, June 19, 2026 | All day |
| Independence Day observed | Friday, July 3, 2026 | All day |
| Labor Day | Monday, September 7, 2026 | All day |
| Indigenous Peoples’ Day / Columbus Day | Monday, October 12, 2026 | All day |
| Veterans Day | Wednesday, November 11, 2026 | All day |
| Thanksgiving Day | Thursday, November 26, 2026 | All day |
| Christmas Eve | Thursday, December 24, 2026 | All day |
| Christmas Day | Friday, December 25, 2026 | All day |
| New Year’s Eve | Thursday, December 31, 2026 | All day |
The day after Thanksgiving is not on APS's current TOU-E holiday list. July 4 falls on Saturday in 2026, so Friday, July 3 is the observed off-peak weekday; Saturday is off-peak anyway because it is a weekend.
How much can timing change the energy charge?
In summer, moving one kWh from the 4-7pm peak to ordinary off-peak hours changes the base energy charge by about 22.051¢. In winter, moving one kWh from peak to the 10am-3pm super-off-peak window changes it by about 29.048¢. Those are per-kWh differences, not guaranteed monthly savings.
- Schedule pool pumps outside 4-7pm weekdays; the pool pump calculator can estimate the energy and timing tradeoff for your equipment.
- Pre-cool before 4pm without setting an unsafe or uncomfortable indoor temperature.
- If you are evaluating battery load-shifting, use the APS battery calculator to compare a TOU-E arbitrage scenario with current program assumptions.
- Use the winter 10am-3pm window only when your billing cycle and weekday calendar qualify.
- Confirm your plan in the APS portal before copying another household's schedule.
Do not confuse TOU-E with a frozen legacy plan
Some APS customers retained a frozen legacy plan with different time windows. For example, Saver Choice Plus uses a 3-8pm weekday window rather than TOU-E's 4-7pm window. APS explains the distinction on its TOU transition page. The plan name printed on your bill is the deciding source.
Frequently asked questions
What are APS off-peak hours on the current TOU-E plan?
On-peak hours are 4pm to 7pm on non-holiday weekdays. All other hours are off-peak, except for the separately priced winter super-off-peak period from 10am to 3pm on qualifying weekdays.
Does APS have super-off-peak hours in summer?
No. The current TOU-E tariff provides the 10am to 3pm super-off-peak period only during November through April billing cycles, on weekdays excluding off-peak holidays.
Are weekends and APS holidays off-peak all day?
Yes. Weekends and APS-designated off-peak holidays are off-peak all day. Fixed-date Saturday holidays are observed on the preceding Friday, and Sunday holidays on the following Monday. Christmas Eve and New Year’s Eve qualify when they fall on a weekday.
