Most Texas electricity shopping is about locking a price and forgetting it. This kind of plan is the opposite bargain — near-total freedom to walk away at any time, in exchange for a price that can move under your feet every single month.

How a Variable Rate Works

On a variable plan, you're billed each month at whatever price per kWh the provider sets for that cycle. There's no contract locking the number in place, and there's generally no penalty for leaving, so in principle you can switch to a better plan whenever you spot one. That's the mirror image of a fixed-rate plan, where the price is held steady for a set term — usually 12 or 24 months — but leaving early can trigger an early termination fee. Variable trades the locked price for freedom; fixed trades the freedom for a locked price. Neither is a trick; they're two different deals for two different needs. Our overview of Texas electricity plan types lays the whole menu side by side.

The Upside: Genuine Flexibility

There are real situations where the freedom is exactly what you want. If you're renting for a few months, waiting on a home sale to close, bridging a short gap between plans, or simply not ready to commit to a year, a variable month-to-month plan lets you keep power on without signing up for a term you'll need to break. In those cases the ability to leave any time — with no fee to escape — is worth more than a locked rate you'd have to pay to get out of. For a genuinely temporary need, variable is often the sensible pick.

The Downside: The Price Can Jump Without Warning

The problem is the same freedom cutting the other way. Because the provider can reset the rate each month, there's nothing stopping it from rising — and it tends to rise at the worst times, such as during summer demand peaks or after the wholesale market spikes. Assuming an energy charge of around 14¢ per kWh as a rough Texas reference point, a variable rate can drift meaningfully above that with little notice, and you may not see it until the bill lands. There's typically no cap you can count on, so your only real defense is to keep watching and be ready to move. For most people, that's more attention than an electricity plan deserves.

The Trap: The Holdover Rate After a Fixed Plan Ends

Here's the version of variable that catches people who never chose it. When a fixed-rate contract expires and you don't sign a new plan, your provider almost always rolls you onto a month-to-month variable or "holdover" rate by default. That holdover rate is frequently well above the competitive fixed rates on offer — it's one of the quietest, most common ways Texas households end up overpaying, sometimes for months before they notice. The fix is simple but time-sensitive: treat your contract-end date as a deadline, not a suggestion. Our guide on what to do when your Texas contract is ending walks through switching cleanly before the holdover rate ever kicks in.

So, Variable or Fixed?

Put simply: a variable-rate plan is a fine tool for a genuinely short-term situation, and a poor default for a settled home. If you'll be somewhere a while, a fixed plan protects you from the seasonal swings and takes the month-to-month guesswork off your plate — and if you want to lock one at a calmer point in the market, our look at when Texas electricity rates are lowest can help you time it. Whichever you choose, judge it by the all-in effective rate at your real usage, not the headline number — that's the figure that actually shows up on your bill.

Common Questions

What is a variable-rate electricity plan?

It is a plan whose price per kWh can change from month to month at the provider's discretion. There is no fixed contract term and usually no early termination fee, so you can switch away whenever you like. That flexibility is the whole appeal — but it also means your rate is not protected, and it can climb, sometimes sharply, from one billing cycle to the next.

Is a variable or fixed rate better in Texas?

It depends on your situation rather than on which is better in the abstract. A variable rate suits genuinely short-term needs — a month-to-month gap, a pending move, a rental you will leave soon — because you can exit anytime. For most households staying put, a fixed-rate plan is the safer choice: it locks your price for the term, so summer peaks and winter cold snaps cannot push your rate up. The trade-off is an early termination fee if you leave early.

Can my provider raise a variable rate whenever they want?

Broadly, yes. By definition a variable rate can change month to month at the provider's discretion, within the terms you agreed to and the disclosures on your Electricity Facts Label. There is no promise it will track any particular index and usually no cap you can rely on, which is why the rate can rise — especially during summer demand or after wholesale-price spikes. Because there is typically no early termination fee, your protection is the freedom to leave, not a locked price.

What rate am I on after my fixed plan ends?

Unless you choose a new plan, you are almost always rolled onto a month-to-month variable or holdover rate — and that default rate is frequently well above competitive fixed rates. It is one of the most common ways Texas households quietly overpay. Watch your contract-expiration notices and line up a new plan before the old one ends so you never sit on the holdover rate.
