APS Off-Peak Hours & Holidays: The 2026 Schedule
These primary sources support the schedule and rate claims in this guide.
On-peak
4-7pm weekdays
Except APS off-peak holidays
Off-peak
All other hours
Including weekends and designated holidays
Winter super off-peak
10am-3pm
Nov-Apr weekday billing cycles; excludes holidays
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.
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 | Thu, Jan 1 | All day |
| Martin Luther King Jr. Day | Mon, Jan 19 | All day |
| Presidents Day | Mon, Feb 16 | All day |
| Cesar Chavez Day | Tue, Mar 31 | All day |
| Memorial Day | Mon, May 25 | All day |
| Juneteenth | Fri, Jun 19 | All day |
| Independence Day observed | Fri, Jul 3 | All day; Jul 4 is also a weekend |
| Labor Day | Mon, Sep 7 | All day |
| Indigenous Peoples’ Day / Columbus Day | Mon, Oct 12 | All day |
| Veterans Day | Wed, Nov 11 | All day |
| Thanksgiving Day | Thu, Nov 26 | All day |
| Christmas Eve | Thu, Dec 24 | All day because it falls on a weekday |
| Christmas Day | Fri, Dec 25 | All day |
| New Year’s Eve | Thu, Dec 31 | All day because it falls on a weekday |
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.
