The Cheapest Time to Do Laundry in Texas

Last updated: October 18, 2026  ·  5 min read

You've probably seen advice to "do laundry at night to save money." In Texas, whether that's true comes down to one thing: what kind of electricity plan you're on. For most households it makes no difference at all — and the real savings are somewhere else entirely.

On a Normal Plan, the Clock Doesn't Matter

Most Texans are on a flat fixed-rate plan: every kilowatt-hour costs the same no matter when you use it. Your bill is simply usage times that one rate, so a load run at midnight and an identical load run at noon cost exactly the same. If that's your plan, do laundry whenever it suits you — the "night is cheaper" tip just doesn't apply.

The Exception: Time-of-Use and Free-Nights Plans

The time of day only changes your cost if you've chosen a plan built around it — a free nights or nights-and-weekends plan, or a time-of-use plan with cheaper off-peak hours. On those, shifting heavy loads into the free or off-peak window is where the savings live. But there's a catch worth understanding: those plans pay for the "free" hours by charging a higher rate during the day. They only come out ahead if you genuinely move a large share of your usage into the free window — running one late load won't do it. That's why you should compare a free-nights plan against a plain fixed rate at your real usage before signing up.

What Actually Costs You: the Dryer

Here's what the time-of-day debate misses. A washing machine uses very little electricity on its own — most of its energy goes into heating water, which is why a cold-water wash is nearly free to run. The electric dryer is the expensive half of laundry, using roughly 2–4 kWh per load to generate heat. So the moves that actually cut your laundry cost work on any plan, any time of day: wash in cold water, run full loads, keep the lint filter clean, and line-dry when the Texas weather cooperates.

Why "Not at Night" Is About the Grid, Not Your Bill

If shifting laundry has any broader value, it's for the grid, not your wallet. Texas electricity demand peaks in the late afternoon and early evening, especially during summer heat waves when ERCOT asks people to conserve. Running heavy appliances late at night or midday instead of 3–7pm eases that peak — and if you're ever on a plan with a peak-pricing component, it protects you too. The common "don't do laundry at night" warnings are really about noise, apartment quiet hours, and not leaving a dryer running unattended while you sleep — all sensible, none of them about your rate.

Common Questions

What is the cheapest time of day to do laundry in Texas?

It depends entirely on your plan. On a standard fixed-rate plan — what most Texans have — a kilowatt-hour costs the same at 2pm as at 2am, so there is no cheaper time of day; do laundry whenever is convenient. The only time of day matters is if you are on a time-of-use or "free nights/weekends" plan, in which case running laundry during the free or off-peak window is genuinely cheaper.

Why shouldn't you do laundry at night?

For cost reasons, you usually can — on a flat-rate plan it makes no difference, and on a free-nights plan night is the cheap window. The "avoid night laundry" advice is mostly about noise, fire safety (not running a dryer unattended while asleep), and apartment quiet hours, not your electricity rate. On the grid side, Texas demand peaks in the late afternoon and early evening, so shifting heavy use to late night actually helps ERCOT.

Does doing laundry at night save money in Texas?

Only on a time-of-use plan. If you have a free-nights or nights-and-weekends plan, moving the washer and especially the dryer into the free window can save real money — but remember those plans charge a higher rate during the day to pay for the "free" hours, so they only pay off if you genuinely shift a lot of usage. On an ordinary fixed plan, night laundry saves nothing.

What costs more to run, the washer or the dryer?

The dryer, by far. A washing machine uses very little electricity itself — most of its energy goes to heating water, so a cold-water wash is cheap. An electric clothes dryer, by contrast, uses about 2–4 kWh per load to make heat. If you want to cut laundry costs, wash in cold water and reduce dryer use (full loads, clean lint filter, line-dry when you can) before worrying about the time of day.
