Time-of-Use Electricity Plans: Are They Worth It in 2026?

Time-of-Use (TOU) electricity plans flip the traditional flat-rate model on its head. Instead of paying a single rate for every kilowatt-hour you consume, your price changes based on when you use power — cheaper at night and on weekends, more expensive during weekday afternoons and early evenings. For some households, TOU can shave 15–25% off the annual bill. For others, it adds hundreds of dollars a year. This guide breaks down who actually wins with TOU in 2026, which states make the math attractive, and how to tell within a single billing cycle whether you should switch back.

What a Time-of-Use Plan Actually Looks Like

A typical TOU plan splits the day into two or three pricing windows: off-peak, mid-peak, and on-peak. Off-peak hours — usually 9 p.m. to 7 a.m. and most or all of weekends — often run 6–9¢ per kWh in deregulated states. On-peak hours, generally 2 p.m. to 7 p.m. on weekdays, can climb to 18–28¢ per kWh or higher in summer. The flat-rate plan you’re probably on today averages those two extremes into a single 12–16¢ rate.

The math is straightforward: if you can move enough of your usage into off-peak hours, you pay less than the flat rate. If you can’t, you pay more — sometimes a lot more, because the on-peak premium is steep.

Who Actually Wins With TOU

TOU rewards three behaviors more than anything else:

1. Overnight EV charging. An EV adds 250–400 kWh per month to a typical household. Charging that load at 6¢/kWh instead of 14¢ saves roughly $20–30 per month per vehicle. For two-EV households, that alone can justify the switch.
2. Pre-cooling and pre-heating with a smart thermostat. Ecobee, Nest, and Honeywell thermostats can run the AC hard from noon to 2 p.m., then coast through the on-peak window with the compressor off most of the time. The same idea works in reverse for heat pumps in winter.
3. Running large appliances on a schedule. Dishwasher delay-start, laundry timers, and pool pumps that run after 9 p.m. easily shift 100–200 kWh per month to off-peak.

Who Loses With TOU

If your household has someone home all day, the math usually breaks down. Stay-at-home parents, work-from-home professionals, and retirees tend to peak their usage during the exact hours TOU penalizes. A single afternoon of running the AC, the dryer, the dishwasher, and the oven during the on-peak window can wipe out a week of off-peak savings.

Households with electric resistance heat (baseboard or furnace coils, not heat pumps) also tend to lose. Resistance heat draws steady high wattage and is harder to shift in time without sacrificing comfort.

State-by-State: Where TOU Plans Are Available

In deregulated states, TOU plans are offered by individual retail suppliers — you have to shop for them. The availability varies:

• Texas: Strong selection. Major retailers like Reliant, TXU, Gexa, and Rhythm offer “Free Nights” or “Free Weekends” plans that function as extreme TOU products. Free nights typically run 9 p.m.–6 a.m. and are paired with a higher daytime rate.
• Pennsylvania: Limited but growing. Constellation and Direct Energy offer TOU options in PECO and PPL territories.
• New York: The default utility (Con Ed, National Grid, NYSEG) offers an opt-in TOU rate that retail suppliers also match. EV owners get a deeper discount via the utility-specific EV rate.
• Illinois: ComEd’s Hourly Pricing program is a true TOU offering with real-time pricing. Most retail suppliers offer a simpler two-tier alternative.
• Ohio, New Jersey, Connecticut, Massachusetts: A handful of suppliers offer TOU, but adoption is lower. EV owners can often access a utility-specific EV charging rate even if their commodity supply comes from a third party.

How to Tell Within 30 Days Whether TOU Is Working

Most utilities now publish hourly usage data through their online portal, going back 12–24 months. Pull last summer’s data, look at the hourly breakdown for a typical July or August week, and run two calculations:

• Flat rate scenario: total kWh × current flat rate
• TOU scenario: off-peak kWh × off-peak rate + on-peak kWh × on-peak rate

If TOU comes out cheaper before you’ve changed any behavior, switching is essentially free money. If it’s within 5%, you’ll probably break even after small adjustments. If TOU comes out 10%+ more expensive on your existing usage pattern, the savings have to come entirely from behavior change — and that’s a much harder commitment to sustain.

The Demand-Charge Trap

A small number of TOU plans — mostly in Texas — layer a demand charge on top of the time-of-use rate. The demand charge bills you based on the highest single hour of usage during the on-peak window each month. One bad hour (the AC, the dryer, and the oven all running at 4 p.m.) can add $30–60 to that month’s bill regardless of total consumption.

Read the Electricity Facts Label (EFL) carefully. If you see “demand” or “kW” charges separate from energy charges, model that into your calculation. Demand charges are rare on residential plans but show up on some commercial TOU offerings.

Smart Home Investments That Make TOU Pay Off Faster

The bigger your fixed load, the harder it is to shift. The bigger your shiftable load, the more TOU rewards you. A few upgrades reliably move the needle:

• Smart thermostat with pre-cooling logic: $150–250. Payback in 6–12 months on TOU.
• Heat pump water heater: $1,500–2,500 installed (often with utility rebates). Can be scheduled to heat overnight only.
• Level 2 EV charger with scheduling: $500–800 installed. Required to capture nighttime EV savings reliably.
• Smart plugs and timers for pool pumps, dehumidifiers, etc.: $20–40 each. Quick wins on shiftable loads.
• Battery storage (Powerwall, Enphase, etc.): $10,000–15,000. Only pencils out where TOU spreads are extreme (5x or more between off-peak and on-peak) and federal/state incentives stack favorably.

Frequently Asked Questions

Can I switch back to a flat-rate plan if TOU doesn’t work for me?
Yes. In most deregulated states you can switch suppliers at any time without an early-termination fee if you’re outside an initial contract term. Some TOU plans have 12-month contracts; read the Terms of Service before signing.

Do I need a smart meter for TOU?
Yes. TOU requires interval (typically hourly) usage data. If your utility hasn’t installed a smart meter yet, you can’t enroll. Most deregulated-state utilities completed smart meter rollout between 2015 and 2022.

What’s the difference between TOU and “Free Nights” plans?
“Free Nights” is an extreme version of TOU. The off-peak rate is literally zero, and the on-peak rate is higher than what a flat-rate plan would charge. They work great for EV owners and night owls; terribly for everyone else.

Are TOU rates the same as real-time pricing (RTP)?
No. TOU uses fixed time blocks (e.g., off-peak 9pm–7am at one rate). RTP follows the wholesale market hour-by-hour. RTP can save more in mild months but exposes you to spikes during heat waves and cold snaps. Only experienced energy nerds should sign up for true RTP.

Will my utility automatically put me on a TOU plan?
Some states (California has done this in the regulated market) are moving toward TOU as the default. In deregulated states, TOU is opt-in only — you choose to switch suppliers to one.

Is TOU worth it for a one-person apartment?
Usually not. The savings scale with how much load you can shift, and a small household has less to shift in absolute terms. Stick with the cheapest flat rate you can find unless you have an EV.

Bottom Line

TOU plans are an excellent fit for EV owners, night owls, and households willing to use a smart thermostat aggressively. They’re a bad fit for stay-at-home households, electric-resistance-heat homes, and anyone unwilling to look at hourly usage data once a month to make sure the math still works. Pull your hourly usage from your utility portal, run the calculation, and treat the first 60 days on TOU as a real-world test. If it doesn’t save money, switch back.
