There’s no single right answer — but there is a wrong one for your situation. Here’s how to tell the difference.
Walk into ten conversations about electricity plans and you’ll hear ten different opinions. Some folks swear by locking in the longest fixed rate they can find. Others ride the variable market and bet they’ll come out ahead over time. Most people are somewhere in between, often without a clear strategic reason for landing where they did.
The truth is that the right plan depends entirely on your situation — your usage patterns, your tolerance for monthly bill swings, your view of where the market is headed, and frankly, how much attention you want to pay to the whole subject. There’s no universal answer. There is, however, a wrong answer for almost every specific situation.
The Three Main Choices
Fixed rate. You pick a plan with a single price per kilowatt-hour, locked in for a term — usually 12, 24, or 36 months. The advantage is predictability. The provider takes the risk that wholesale prices will move against them, and they bake the cost of that risk into your rate. The disadvantage is that you’re paying a small premium for that certainty, and if market prices drop during your term, you’re stuck.
Variable rate. Your price floats with market conditions. Sometimes that’s cheaper than fixed, sometimes considerably more expensive. Variable rates can look attractive when the market is calm, and can produce shocking bills during periods of stress. For most households, variable rates are not the right choice — they reward sophistication and active monitoring that most of us don’t have time for.
Indexed or pass-through. A variation on variable, where your rate is tied directly to wholesale market prices plus a fixed adder for the provider’s margin. These can work well for businesses with the operational flexibility to shift load away from peak hours. For typical homes, they’re risky — during a Winter Storm Uri or similar event, indexed customers can see bills in the thousands of dollars for a single week.
Questions to Ask Yourself
Before shopping for a plan, take a few minutes to think through the following:
- How much electricity do you use in a typical month, and how does it vary by season? This is the single most important number, and it’s right there on your bills from the past year. A house that uses 2,500 kilowatt-hours in August and 600 in April has very different needs than one that’s relatively flat year-round.
- Could you absorb a much higher bill if things got bad? If a 50 percent jump in your monthly electric bill would be a real problem, fixed-rate is almost certainly the right choice.
- How much attention are you actually willing to pay? Variable and indexed plans require active management. If you’re going to set it and forget it for a year, fixed is the only sensible option.
- When does your current plan expire? Almost every fixed-rate plan rolls into a much higher month-to-month rate when it ends. Calendar that date and start shopping 30 to 60 days early.
The right plan is the one that fits how you actually live and use power — not the one with the lowest sticker price or the longest term. Get those questions answered first, then shop.
Common Mistakes to Avoid
A few patterns that consistently cost Texans money:
- Shopping on the headline rate. That number on the front of the offer assumes a specific level of usage — typically 1,000 or 2,000 kilowatt-hours per month. If your actual usage is different, your effective rate will be too. Always check the Electricity Facts Label, which shows what your average price will be at different usage levels.
- Letting the plan auto-renew. Auto-renewals almost always happen at significantly worse pricing than what’s available in the open market. The provider isn’t being malicious — they’re just not your friend. Shopping at renewal is your job.
- Ignoring the fine print on minimum-usage fees. Some plans charge an extra fee in months when you use less than a certain amount. If you’re a snowbird, or your family travels in summer, those fees can add up.
- Not factoring in delivery charges. When you compare two plans, the energy charge is what changes — but the delivery charges from your wires company are the same either way. A plan that looks 20 percent cheaper on the energy line might only be a small percentage cheaper on the total bill.
For Small Business Owners
Most of the same principles apply, with two additional considerations.
First, commercial bills typically include demand charges based on your peak 15-minute usage during the billing period. That makes the contract structure conversation more complex, because you’re not just managing the energy charge — you’re managing your peak demand. A walk-through of your operation with someone who understands these things can sometimes turn up easy savings.
Second, longer contract terms tend to be more available and more competitively priced for businesses than for households. If you’re a stable operation with predictable usage, locking in 36 months at today’s pricing might be a better move than waiting.
Whatever you decide, the worst choice is no choice at all. Defaulting onto a holdover rate, or auto-renewing without shopping, is how thousands of Texas families and businesses end up paying more than they need to. A couple of hours of attention every year or two is the cheapest investment in your monthly budget.
