7 real reasons your bill went up
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.
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.
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.
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.
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.
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.
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.
