Ranked by how often they actually happen

7 real reasons your bill went up

1

You missed a usage-based bill credit

Many Texas plans advertise a low rate that only kicks in above (or below) an exact kWh threshold — often 1,000 kWh. Miss it by even a few kWh and you lose the entire credit, sometimes swinging your bill by $75–$150 in a single cycle. This is the single most common cause of an unexpectedly high bill on a credit-based plan.

2

Your promotional rate expired

Fixed-rate plans often start with a teaser rate for the first few months, then roll to a much higher variable rate once the promo period ends — sometimes without any notice beyond the original contract fine print.

3

Weather-driven usage spike

Texas summers and winter cold snaps push HVAC systems hard. A few extra degrees on either extreme can meaningfully raise your kWh usage even if your habits haven’t changed.

4

A longer billing cycle than usual

A 33-day cycle instead of a 30-day one means more usage, more delivery charges, and a higher bill — even at an identical daily rate. Check your bill’s service period dates before assuming your rate changed.

5

More people or devices in the house

Guests staying over, a new appliance, a home office setup, or a new EV charger all add real, sustained kWh that won’t show up as a rate change — just a usage change.

6

A minimum usage fee — the opposite of a credit

Some plans penalize you for using too little electricity. If your bill has an unfamiliar line-item fee and you used less than usual, check the EFL for a minimum usage charge.

7

TDU delivery rates changed for everyone in your area

Delivery charges (Oncor, CenterPoint, AEP Texas, TNMP) are set by state regulators and periodically adjusted for every customer in a territory, regardless of REP. Not something any provider controls — see our full breakdown of Texas electricity fees.

High electric bill — FAQ

Why is my electric bill so high even though I didn’t use more electricity?

The most common cause on a credit-based plan is missing the usage threshold for a bill credit — falling just short of 1,000 kWh (or whatever your plan’s threshold is) can cost you the entire credit even if your usage barely changed month to month. A longer billing cycle or a TDU delivery rate change can also raise your total without any change in your habits.

How do I know if I missed my bill credit threshold?

Check your bill for a credit threshold in kWh (often 1,000) and compare it to your total usage for the cycle. If you were close but under, that’s very likely the cause. Upload your bill to our free Bill Analyzer and we’ll check this for you automatically.

Is it normal for a Texas electric bill to double?

It can happen, but it’s almost always explained by one of a few specific things: a promotional rate expiring and rolling to a much higher variable rate, or falling short of a large usage-based bill credit. See our dedicated guide on electric bills doubling in Texas for the full breakdown.

Can I get my money back if I missed a bill credit by a small amount?

Bill credit thresholds are contractual and REPs don’t typically make exceptions for narrowly missing one — which is exactly why tracking your usage in real time against the threshold matters. HitMyCredit alerts you before the cycle ends if you’re on track to fall short, while there’s still time to adjust usage.
