Why Is My Electricity Bill So High in Texas?

Quick answer: Your Texas bill comes in higher than the advertised rate because that headline "¢ per kWh" is an energy-only price quoted at exactly 1,000 kWh — one of just three usage points (500, 1,000 and 2,000 kWh) every Electricity Facts Label must publish, and the one providers tune to look cheapest. Your real bill then adds regulated TDU delivery charges — about $54.71 a month on CenterPoint, $58.55 on AEP North, $60.14 on AEP Central, $64.36 on Oncor and $72.52 on TNMP at 1,000 kWh per the PUCT's official August 2026 rate summary, identical for every retail provider in your area — plus any base or minimum-usage fees. And because many "cheap" plans hang a bill credit on hitting 1,000 kWh, using less electricity can cost you more: fall below the threshold and the credit disappears (the 1,000 kWh illusion). Add it all back and your effective rate is usually several cents per kWh higher than the number you shopped on.
A real Texas plan where using less costs more
Here is the cliff priced on an actual plan filed in Texas right now. Texans Choice Power LLC Texas Instant 12 advertises 13.5¢ per kWh — the number you see on the shopping sort, quoted at exactly 1,000 kWh. At 1,000 kWh it bills $135.00 for energy. Use 50 kWh less — just 950 kWh — and the same plan bills $141.08, an effective 14.9¢ per kWh. That is $6.08 more for using less power. Nothing went wrong with your meter — you simply fell under the credit threshold the plan was engineered around.
Energy charge only; TDU delivery is separate and identical across providers. Figures are computed from this plan's published Electricity Facts Label price points using Real-Rate Interpolation, from plan data synced October 18, 2026. This figure is deliberately conservative: a real bill credit is an all-or-nothing step, while interpolation treats it as a gradual ramp, so the actual penalty for missing the threshold on this plan is larger than the number shown.

Why is my electricity bill higher than the advertised rate?
Your bill is higher than the advertised rate because that headline "¢ per kWh" is an energy-only price quoted at exactly 1,000 kWh — the middle of the three EFL price points (500, 1,000 and 2,000 kWh), and the one providers optimise. Your real bill adds three things the advertised number leaves out: regulated TDU delivery charges (about $54.71 a month on CenterPoint, $64.36 on Oncor and $72.52 on TNMP at 1,000 kWh, identical for every provider in your area), any base or minimum-usage fees, and the fact that your usage almost never lands on exactly 1,000 kWh. That last gap bites hardest on a bill-credit plan tuned for 1,000 kWh: fall under the threshold and you forfeit the entire credit, so a lighter month can cost more than a heavier one — on Texans Choice Power LLC Texas Instant 12, dropping from 1,000 to 950 kWh currently costs you $6.08 extra. Add those back and your effective rate is usually several cents per kWh higher than the number you shopped on.

The "Hidden" Cost: TDU Delivery Charges
Even if you find a cheap 10¢ rate, your bill might still be high due to Transmission and Distribution Utility (TDU) fees. These are non-negotiable charges from companies like Oncor or CenterPoint that cover the maintenance of poles and wires. At 1,000 kWh of usage they currently total roughly:
| TDU (service area) | Delivery charge at 1,000 kWh |
|---|---|
| CenterPoint Energy (Houston) | ~$54.71 — lowest |
| AEP Texas North | ~$58.55 |
| AEP Texas Central | ~$60.14 |
| Oncor (Dallas–Fort Worth) | ~$64.36 |
| TNMP | ~$72.52 — highest |
You cannot choose your TDU — it is decided entirely by where your meter sits — and the charge is identical for every retail provider in your area. That means delivery never changes which plan is cheapest for you, but it does explain a large slice of the gap between the advertised rate and the number at the bottom of your bill.

Top 5 Reasons for High Bills
Inefficient HVAC Usage
Air conditioning accounts for roughly 50% to 70% of a Texas home's energy consumption. If your unit is over 10 years old or your insulation is poor, your kWh usage will skyrocket during 100°F days. See why your Texas bill spikes in summer for how that usage jump also changes which plan is cheapest.
Expired Fixed-Rate Contracts
When your contract ends, providers often move you to a "Holdover" or variable rate. These market-based rates are significantly higher than fixed-term contracts.
Minimum Usage Fees
Some plans penalize you for using *too little* electricity. If you use less than 1000 kWh on certain "tiered" plans, you may be hit with a $20 fee that raises your effective rate per kWh.
Impact of Rate on Monthly Cost
| Monthly Usage | Budget Rate (11¢) | Out-of-Contract (18¢+) |
|---|---|---|
| 1,000 kWh (Small Apt) | $110 | $180 |
| 2,000 kWh (Avg Home) | $220 | $360 |
How to Lower Your Bill Immediately

- ✅ Set Thermostat to 78°F in Summer
- ✅ Clean AC Condenser Coils
- ✅ Check Window Seal Weatherstripping
- ✅ Use Ceiling Fans (Counter-Clockwise)
- ✅ Avoid "Peak-Time" Laundry Usage
Frequently Asked Questions
What runs up your electric bill the most?
In Texas, air conditioning runs up your electric bill the most — cooling can be close to half of a summer bill. After HVAC, the biggest drivers are an expired contract on a high variable rate, water heating, pool pumps, and electric heating in winter. Plan choice and thermostat setting are the two levers with the largest impact.
Why is my electricity bill higher this month?
The most common reasons for a sudden spike include increased HVAC usage due to Texas heat, the expiration of a fixed-rate contract moving you to a higher month-to-month variable rate, or increases in TDU delivery charges.
What is a normal electricity bill in Texas?
While it varies by home size, the average Texas household bill ranges from $120 to $180 per month. During peak summer months, this can easily exceed $300 for larger homes.
Why is electricity so expensive in Texas?
Honestly, it's less that Texas electricity is expensive and more that Texas bills are large. Texas retail rates sit near the U.S. average — sometimes below it — thanks to a competitive market and cheap wind and gas. What runs bills up is usage: long, hot summers mean heavy AC, so even an average rate on a lot of kWh adds up. The other culprit is the advertised-rate trap — the 1,000 kWh illusion — where the plan that looked cheapest isn't what you actually pay. The fix isn't leaving Texas; it's trimming peak usage and picking the plan that's genuinely cheapest at your real usage.
