As June heat settles across Texas, a typical household’s electricity bill climbs fast. In Houston, Dallas, and San Antonio—where air conditioning runs 16+ hours daily—bills can spike from $100 to $300+ per month. But here’s the difference between panic and protection: a fixed-rate electricity plan. When you lock in a rate of 12¢ per kilowatt-hour instead of riding the Texas deregulated market’s average of 14.66¢, you’re looking at $320–500 in annual savings.
Texas is one of the few states where residential customers can actually choose their electricity provider. Thanks to deregulation, millions of Texans have access to dozens of retail electric providers (REPs) competing for their business. That competition is your leverage—if you know how to use it.
What Is a Fixed-Rate Electricity Plan?
A fixed-rate electricity plan locks your energy rate (the price per kilowatt-hour, or kWh) for the duration of your contract—typically 6, 12, or 24 months. During that period, your rate doesn’t move regardless of what happens in the wholesale energy market.
This matters enormously in Texas. The Electric Reliability Council of Texas (ERCOT) wholesale market is notoriously volatile. During Winter Storm Uri in February 2021, spot prices briefly hit $9.00/kWh—7,000% above normal—leaving customers on variable-rate plans with utility bills in the thousands.
⚡ Fixed vs. Variable: The Key Difference
Fixed-rate plans offer price certainty for a set contract period. Variable-rate plans fluctuate month-to-month with the wholesale market—cheaper some months, unpredictably expensive during peak demand.
How Texas Electricity Pricing Works
Your monthly bill has three main components: your energy charge (the kWh rate you negotiate), transmission and distribution charges (TDSP fees—these are fixed and passed through regardless of provider), and any monthly base charges your REP applies.
| Bill Component | Avg. Monthly Cost | Negotiable? |
|---|---|---|
| Energy Charge (12¢/kWh × 1,100 kWh) | $132 | Yes — shop REPs |
| TDSP Delivery Charge | $35–55 | No — set by utility |
| Monthly Base Fee | $5–10 | Varies by plan |
| Taxes and Fees | $8–15 | No |
| Total Estimate | $180–210 | — |
The average Texas home uses around 1,176 kWh per month (EIA data). At 12¢/kWh that’s $141.12 in energy charges versus $172.25 at the 14.66¢ market average—a $31/month difference that adds up to $372/year.

How to Find the Best Rate for Your Home
Shopping Texas electricity plans takes about 15 minutes and can save you hundreds of dollars. Here’s the process:
- Pull your last 12 months of utility bills to find your average monthly kWh usage. Higher usage makes your per-kWh rate more important; lower usage makes monthly base fees matter more.
- Go to PowerToChoose.org and enter your zip code. This state-run site shows all available plans from all licensed REPs.
- Filter by “Fixed Rate” and sort by price per kWh at your actual usage level (not the advertised rate, which is often calculated at exactly 500, 1,000, or 2,000 kWh).
- Check the Electricity Facts Label (EFL) for every plan you consider. This legal document shows the all-in price at different usage tiers, cancellation fees, and contract terms.
- Calculate total cost, not just rate. A 10.5¢ plan with a $9.95/month base fee can cost more than an 11.2¢ plan with no base fee if you use under 800 kWh/month.
- Enroll online—most providers switch you within 1–2 billing cycles with no interruption in service.
When to Lock In vs. Go Variable
Fixed-rate plans make the most sense when:
- Summer peak season is approaching (rates often rise in May–June)
- You’re on a tight budget and need predictable monthly bills
- Wholesale market forecasts suggest price increases
- You plan to stay in your home for 12+ months
Variable-rate plans occasionally make sense when:
- You’re moving within 3–6 months and want to avoid cancellation fees
- Wholesale prices are historically low and unlikely to spike
- You have high energy flexibility (can shift usage to off-peak hours)
🌡️ Texas Summer Rule of Thumb
If you’re signing a new plan between April and July, lock in a fixed rate. Summer demand pushes wholesale prices up, and variable-rate plans absorb those increases directly. The savings potential from a good fixed rate are greatest when secured before the heat spike.
Understanding Your Electricity Facts Label
Texas law requires every plan to publish an Electricity Facts Label (EFL)—a standardized one-page document that makes apples-to-apples comparison possible. Before signing any contract, review these key fields:
| EFL Field | What to Look For |
|---|---|
| Average Price (500/1000/2000 kWh) | Find your actual average usage tier—don’t rely on the advertised rate |
| Contract Term | 12 or 24 months is standard; longer locks price but raises cancellation risk |
| Early Termination Fee | $150–250 is typical; weigh against savings before committing |
| Monthly Recurring Charge | Any flat fee that adds to your bill regardless of usage |
| Renewable Content % | Important if green energy matters to you; 100% renewable is available |
Avoiding Common Traps
The Texas electricity market is competitive but not always consumer-friendly. Watch for:
- Teaser rates: An ultra-low rate that applies only at exactly 1,000 kWh/month. Above or below that usage, you pay more. Always check the 500 kWh and 2,000 kWh price tiers.
- Bill credits that create hidden tiers: “Get a $50 credit when you use over 1,000 kWh” structures make you burn energy to save money.
- Auto-renewal at variable rates: Many fixed-rate plans roll to a variable rate when the contract expires. Set a calendar reminder 45 days before expiration.
- “Free nights” plans: These can be great for households that run laundry and dishwashers at night, but the daytime rate is often 15–18¢/kWh to compensate.
Smart Home Strategies to Maximize Your Fixed-Rate Plan
Once you’ve locked in a competitive rate, small smart home upgrades compound your savings:
- Smart thermostat (Ecobee or Nest): Pre-cool the house during off-peak hours and let temperature drift slightly during peak demand (3–7 PM). Can reduce cooling costs by 15–20%.
- Smart plugs on major appliances: Shift dishwasher, washer, and dryer cycles to early morning. On a 12¢ fixed-rate plan, this won’t change your per-kWh cost, but if you’re on a time-of-use plan, it matters significantly.
- Ceiling fans: Running ceiling fans on low allows you to raise your thermostat setpoint by 4°F with no comfort difference—saving roughly 3–5% per degree on your cooling bill.
- Attic insulation audit: Texas homes often have insufficient attic insulation. The Department of Energy recommends R-38 to R-60 in the Texas climate zone. A $1,200 insulation upgrade can pay back in 3–4 years through reduced HVAC runtime.
Bottom Line
In a state where extreme weather events have rewritten the rules of residential energy costs, a fixed-rate electricity plan is the most straightforward hedge available to Texas homeowners. Fifteen minutes on PowerToChoose.org, your average monthly kWh usage, and the EFL for any plan you’re considering is all it takes to make an informed switch that saves real money.
The best time to lock in your summer rate was a month ago. The second best time is today.
