Time-of-Use Electricity Plans in Texas (2026)
Free nights. Free weekends. Peak-hour pricing. Texas REPs offer more time-of-use products than any other state — but the savings depend almost entirely on whether you can shift your usage.
If I switched to TOU in Texas, when are peak hours?
Across the 0 Texas utilities offering time-of-use plans, peak windows fall on weekday afternoons — most schedules concentrate peak pricing between roughly 2pm and 7pm, with off-peak running overnight and on weekends. There are 0 current TOU tariffs on file in the URDB. The exact peak window varies by utility; see each utility's heatmap below.
Time-of-use electricity in Texas
Texas residents have a different relationship with time-of-use plans than customers in regulated states. The Public Utility Commission of Texas regulates Oncor, CenterPoint, AEP Texas, and TNMP — the wires companies that deliver power — but the retail energy product, including time-of-use options, is sold by retail electric providers (REPs) in the competitive market. URDB documents very few TOU schedules on the Texas TDU side because TDU tariffs are primarily delivery charges. The time-of-use action in Texas happens at the REP layer.
Is time-of-use worth it in Texas?
In Texas, "free nights" and "free weekends" plans from REPs are the most common time-of-use products. They benefit households that can shift laundry, dishwashers, and EV charging into the free window — typically 9pm-6am or all weekend. Households running heavy air conditioning during peak summer afternoons often pay more on these plans, not less. Check the plan's EFL carefully before signing up.
The honest answer for most households is: it depends on how much of your usage you can move. Time-of-use plans are a swap — you accept a higher rate during peak hours in exchange for a lower rate during off-peak hours. If your home runs heaviest during peak hours and you can't shift it, you'll lose money. If you can shift even 30-40% of your usage into off-peak windows, you'll usually come out ahead.
Good candidates for TOU
- EV owners who charge overnight
- Households with battery storage
- Remote workers with flexible schedules
- Pool/spa pumps on timers
- Smart thermostats with pre-cooling
Poor candidates for TOU
- All-day occupied homes (retirees, families with young kids)
- Older A/C systems that run constantly in summer
- Resistive electric heat in winter
- Households without smart appliances or schedule flexibility
Run the math first. Look at your last 12 months of usage hour-by-hour if you have a smart meter, or estimate the percentage of your usage that already falls in off-peak hours. If less than 50% is off-peak, TOU probably costs you money. Our Bill Grade tool evaluates this for free.

Why peak hours exist on Texas's grid
ERCOT runs Texas. Peak demand hits in late afternoon and evening during summer cooling season, when air conditioning load combines with sunset solar drop-off. Wholesale prices in those hours can be 10-20× the off-peak average. REP time-of-use plans are how those wholesale price swings reach residential customers.
TOU rates exist because wholesale electricity costs vary hour by hour. The retail price most households pay is a blended average across the entire month — cheap and expensive hours mixed together. A TOU rate unblends them: you pay closer to the actual hourly cost. That's good news if your usage skews to cheap hours, bad news if it skews to expensive ones.
