Quick Answer

Texas electric bills average $177/month but spike to $300+ in summer. The 8 most common causes: wrong rate plan, AC overuse, TDU charges (Oncor, CenterPoint), poor insulation, phantom loads, peak pricing, and billing errors. Compare rates on ElectricRates.org to fix the #1 cause.

Why Texas Electric Bills Run High

Texas electricity bills are higher than you'd expect. The reasons aren't always obvious.

The average Texas household uses 1,096-1,176 kWh per month.[1] That's about 25% more than the national average of 863 kWh. Why? Long, brutal summers where AC runs constantly. Larger-than-average homes (Texas averages 2,170 square feet). And in many areas, electric heating instead of natural gas.

At current rates around 15.49¢/kWh, the average monthly bill runs about $177. But summer bills can easily hit $300, $400, or more in a poorly-insulated home with an aging AC system.

Here's the thing: most high bills have fixable causes. Some you can solve today. Others take more effort but pay off for years. Let's diagnose what's driving your bill up.

1. You're on the Wrong Rate Plan

The #1 reason for high Texas electric bills? People overpay for their rate plan.

Many Texans never shopped for electricity. They accepted whatever rate their provider offered when they moved in, or rolled onto a month-to-month variable rate after their contract expired.

Rate comparison:

Plan TypeTypical RateMonthly Cost (1,000 kWh)
Variable rate (expired contract)18-25¢/kWh$180-$250
Fixed rate (shopped)8-12¢/kWh$80-$120
Potential savings$60-$130/month

Over a year, that's $720-$1,560 in potential savings.

Fix it:
- Check your current rate on your bill
- Compare against offers on Power to Choose or ElectricRates.org
- If you're paying more than 14¢/kWh, you're almost certainly overpaying

2. Your AC Is Working Overtime

Air conditioning typically accounts for 50-70% of a Texas electric bill during summer.

When it's 100°F outside for weeks straight, your AC runs constantly. That's expensive.

AC cost breakdown:

FactorValue
3-ton central AC usage3,500 watts/hour
Running 12 hours/day42 kWh daily
At 12¢/kWh$5/day or $150/month

SEER efficiency matters:

AC AgeSEER RatingEfficiency
10-15+ years oldSEER 10-12Baseline
Modern unitsSEER 15-2130-50% less electricity

Fix it:
- Set thermostat to 78°F when home, higher when away
- Replace air filters monthly
- Consider a smart thermostat that learns your schedule
- If system is old, calculate whether a new unit pays for itself

3. TDU Delivery Charges Add Up

About 40% of your Texas electric bill isn't from your REP at all. It's TDU delivery charges.

Your Transmission and Distribution Utility (Oncor, CenterPoint, AEP Texas, or TNMP) charges for delivering electricity through the grid. These charges are the same regardless of which provider you choose.

Current TDU charges:[2]

ComponentCost
Monthly fee$4-8
Per-kWh rate5-6¢
Total at 1,000 kWh$54-68

That's $54-68 before you pay a dime for actual electricity.

Fix it:
- You can't change TDU charges
- When shopping, look at the "average price at 1000 kWh" (includes TDU)
- Don't compare just the energy rate—that's only part of the picture

4. Your Home Leaks Energy

Poor insulation and air leaks make your HVAC work harder. That shows up on your bill.

Many Texas homes, especially those built before 2000, have inadequate attic insulation. Hot Texas sun beats down on the roof, radiating heat into your living space. Your AC runs longer to compensate.

Energy efficiency impact:

Home ConditionEnergy UseOn $200 Summer Bill
Poorly-sealed homeBaseline$200
Properly-sealed & insulated15-30% less$140-170
Monthly savings$30-60

Fix it (from free to bigger investment):

ActionCostImpact
Seal gaps (doors/windows)FreeMedium
Weatherstripping$10-50Medium
Insulate exposed ductwork$50-200High
Add attic insulation (R-38+)$1,000-2,500Highest

Some Texas utilities offer rebates for insulation improvements.

5. Phantom Loads Drain Power 24/7

Devices use electricity even when you're not using them. It adds up faster than you'd think.

Common phantom load costs:

DevicePower DrawMonthly Cost (12¢/kWh)
Cable box25 watts$2.16
Game console (standby)10-15 watts$1.00
Smart TV5-10 watts$0.65
Computer monitor3-5 watts$0.35

Multiply by a dozen always-on devices and phantom loads can account for 10-15% of your total usage.

The U.S. Department of Energy estimates phantom loads cost the average home $100+ per year.[3]

Fix it:
- Use smart power strips that cut power when devices aren't in use
- Unplug phone chargers when not charging
- Enable power-saving modes on game consoles and computers
- That second garage refrigerator? It costs $8-15/month to run

6. You're Paying Peak Rates

Some Texas plans charge more during peak hours. If you run appliances at the wrong time, your bill suffers.

Time-of-use plans and some variable rate plans charge premium rates during hot summer afternoons when ERCOT demand is highest.

Typical TOU rate structure:

Time PeriodHoursTypical Rate
Peak (summer)1pm-7pm15-20¢/kWh
Off-peakAll other times8-10¢/kWh
DifferenceNearly 2x

Running dishwasher, laundry, or pool pump during peak hours? You're paying premium rates for activities that could wait.

Fix it:
- Check your plan terms for time-based pricing
- Shift heavy usage to early morning or late evening
- Run dishwasher after 9pm
- Do laundry on weekends
- A programmable timer on your pool pump pays for itself quickly

7. Billing Errors and Estimated Reads

Sometimes the problem isn't usage at all. It's a billing mistake.

Most Texas meters are smart meters now, but errors still happen.

Common billing errors:

Error TypeWhat Happens
Estimated readsBill based on guess, not actual usage
Rate misapplicationWrong plan rate after switching
Wrong addressCharges for someone else's meter

If your bill suddenly spikes without a matching usage increase, or if the kWh shown doesn't match your smart meter data, investigate.

Fix it:
1. Register at SmartMeterTexas.com to track actual usage (15-minute intervals)
2. Compare your meter data against your bill
3. If they don't match, contact your provider first
4. If that fails, file a complaint with the PUC of Texas

How to Lower Your Texas Electric Bill

Most Texas households can cut their electric bill 20-40% with the right combination of fixes.

Quick wins (do today):
- Shop for a better rate—saves $50-100/month
- Set AC to 78°F when home, 85°F when away
- Replace air filters
- Unplug unused devices

Medium effort (this month):
- Install a smart thermostat
- Seal air leaks around doors and windows
- Use smart power strips
- Shift heavy usage to off-peak hours

Bigger investments (big payoff):
- Add attic insulation
- Upgrade to a high-SEER AC unit
- Install energy-efficient windows
- Consider solar panels

Start with rate shopping. It's free, takes 10 minutes, and often delivers the biggest savings.

Frequently Asked Questions

What is the average electric bill in Texas?

Texas households pay about $177 per month on average, based on 1,096-1,176 kWh monthly usage at around 15.49¢/kWh. Bills vary significantly by season—summer bills often run $200-400+ due to heavy AC usage, while spring and fall bills may drop to $100-150.

Why is my electric bill so high when I'm barely home?

Even when you're away, your AC runs to maintain temperature, your refrigerator operates 24/7, and phantom loads from always-on devices drain power. If you travel frequently, consider raising the thermostat to 85°F while away and unplugging non-essential devices.

How much does AC cost to run in Texas?

Air conditioning typically accounts for 50-70% of summer electric bills in Texas. A 3-ton central AC running 12 hours daily at 12¢/kWh costs about $150/month. Older, inefficient units can cost significantly more.

Why did my electric bill double this month?

Common causes of sudden bill spikes include: extreme weather requiring more AC or heating, expiration of a promotional rate, switch to variable pricing, a malfunctioning appliance, or a billing error. Check your rate, compare kWh usage to previous months, and verify your meter data.

Do smart thermostats really save money in Texas?

Yes. The EPA estimates smart thermostats save 8-15% on heating and cooling costs. In Texas, where AC dominates summer bills, that can mean $15-40 monthly savings. Smart thermostats pay for themselves within 6-12 months for most households.
