Fixed vs Variable Electricity Rates

In Texas's deregulated electricity market, you choose your rate structure. Understanding the difference could save you hundreds—or protect you from unexpected spikes.

Texas Market Warning

During Winter Storm Uri (2021), some variable-rate customers saw bills exceeding $10,000 for a single month. Texas's wholesale market can be extremely volatile during extreme weather.

Fixed-Rate Plans

Your rate per kWh is locked in for the entire contract term. No surprises, no matter what happens in the market.

  • Predictable monthly bills
  • Protected from market volatility
  • Easier budgeting
  • Peace of mind during extreme weather

Drawbacks:

  • Early termination fees ($50-200)

Our Recommendation

For Most Texas Households: Choose Fixed-Rate

The peace of mind and protection from extreme weather events outweighs the potential savings from variable rates. Texas's grid is uniquely vulnerable to price spikes during heat waves and cold snaps.

Exception 1: If you're only in Texas for 3-6 months, variable may make sense.

Exception 2: If you actively monitor rates and can switch quickly, variable can work.

Exception 3: If you have solar + battery and minimal grid usage.

How to Shop for Texas Electricity

1. Use PowerToChoose.org

The official Texas comparison site. Enter your zip code and usage to see all available plans. Look at the "Price per kWh" column for true comparison.

2. Check the EFL

Every plan has an Electricity Facts Label (EFL). This shows the true rate at 500, 1000, and 2000 kWh usage levels, including all fees.

3. Watch for Hidden Fees

Some plans have minimum usage fees, base charges, or "free nights" gimmicks that increase daytime rates. Always check the EFL.

4. Set a Renewal Reminder

Fixed-rate contracts auto-renew to variable rates when they expire. Set a calendar reminder 2 weeks before your contract ends.
