Free Nights & Weekends in Texas: Is the 'Free' Actually Free?

TL;DR

Free nights and weekends plans zero out the energy charge during a set window — usually nights, weekends, or both — but make up for it with a much higher rate the rest of the time, and the delivery (TDU) charge keeps applying around the clock either way. Most households use the majority of their electricity during the day, so unless you can genuinely shift half or more of your usage into the free window, a flat fixed-rate plan is usually cheaper.

The ads you’ve seen

You’ve seen the ads. “Free electricity from 9pm to 6am.” “Free weekends, every weekend.” Somewhere in Texas right now, a billboard is promising free power.

Here’s the thing providers don’t put in bold letters: nobody gives away electricity for free. The hours that aren’t free just got more expensive to pay for it.

How these plans actually work

Free nights and weekends plans are a type of time-of-use (TOU) plan. Instead of one flat rate all day, you get two: a free or near-free rate during a set window — usually nights (often 9pm–6am), weekends, or both — and a much higher rate during the remaining hours, often close to triple what a standard fixed-rate plan charges.

Texas has more of these plans than almost any other state, largely because ERCOT’s grid sees a significant demand drop overnight and on weekends. Retail providers use free-hour pricing to shift usage into those low-demand windows, and several major Texas providers actively market a version of this plan structure.

One detail that catches almost everyone off guard: the “free” part usually only covers the energy charge. The transmission and delivery (TDU) fee — commonly in the 4–6¢/kWh range, set by your local utility rather than your retail provider — still applies during your free hours on most plans. So “free” rarely means your bill for those hours is actually $0; it’s closer to paying delivery only.

The math providers don’t lead with

Here’s the question that decides whether one of these plans is a good deal or a bad one: how much of your electricity use can you actually move into the free window?

Most Texas households can’t move much. Typical residential usage skews heavily toward daytime and evening hours — running the AC, cooking, laundry, working from home, all the ordinary things a home does while people are awake and around. Comparisons published by plan-review sites generally suggest that once daytime usage climbs past roughly 30–40% of total usage, a free-nights plan tends to cost more than a standard fixed-rate plan, and guidance from several of those comparisons puts the realistic break-even point closer to 50% of usage shifted into the free hours. Daytime rates on these plans are also frequently cited as running noticeably higher than a comparable fixed-rate plan’s flat rate — sometimes closer to double.

The rule of thumb from people who’ve actually run the numbers: unless you can genuinely shift half or more of your usage into the free hours, a flat fixed-rate plan is usually cheaper — sometimes by a wide margin.

Who actually comes out ahead on these plans:

• Night-shift workers who are asleep (not running AC and appliances) during the day
• Households that are away from home most weekdays and do laundry, dishwashing, or EV charging on weekend or overnight schedules
• Homes running smart automation that deliberately shifts heavy loads — EV charging, pool pumps, water heaters — into the free window on purpose

If that’s not your household, the “free” hours are likely subsidizing a much more expensive daytime rate than you’d pay elsewhere.

How to check before you switch

Before enrolling in a free-nights or TOU plan, do this:

1. Pull your actual usage pattern, not a guess. If you have Smart Meter Texas access, look at your 15-minute interval data and see what share of your kWh genuinely falls in the plan’s free window.
2. Read the EFL’s daytime rate, not the headline rate. The advertised number is usually the free rate or a blended estimate — the number that matters is what you pay per kWh during the hours you’ll actually be using power.
3. Check whether the TDU delivery charge is included in “free.” If it isn’t, your free hours still cost something — just less than peak hours.
4. Do the comparison against a flat-rate plan at your real usage, not at the provider’s assumed usage split. A plan that looks cheap at an assumed 50% overnight usage can be expensive at your actual, much lower, overnight share.

A note on where WattKicker stands today

We built WattKicker to show people the real math behind their electricity bill — the numbers providers bury, not the ones they put in bold. Time-of-use and free-nights plans are the hardest version of that problem, because the real cost depends entirely on when you use power, not just how much.

We don’t calculate TOU billing yet. If you upload an EFL for a free-nights or TOU plan, WattKicker will tell you that directly rather than quietly giving you a flat-rate estimate that doesn’t reflect how these plans actually bill. We’d rather say “we can’t do this part yet” than hand you a number that looks precise and isn’t.

If you’re on one of these plans, or considering one, the checklist above is the honest version of what we’d want a tool to tell you anyway — use it before you sign anything.
