Texas Calculator
Control your energy costs
Updated for 2025 with real Texas rates, brackets, and regulations
Texas has a unique deregulated electricity market through ERCOT (Electric Reliability Council of Texas), meaning you can choose from 100+ electricity providers and shop for the best rates at powertochoose.org. While this competition can save money, it also means rates vary widely and summer AC bills can spike 50-60%. The 2021 Winter Storm Uri exposed the risks of variable-rate plans when bills skyrocketed to thousands of dollars. This calculator estimates your monthly utility costs based on home size, season, and provider type, with ERCOT-specific considerations.

Frequently Asked Questions
What is ERCOT and how does deregulation work?
ERCOT operates the Texas power grid independently from the US national grids. Deregulation means you choose your electricity provider (Retail Electric Provider, or REP) from 100+ companies. Compare rates at powertochoose.org. You can choose fixed-rate (stable) or variable-rate (fluctuating) plans.
How much do utilities cost in summer vs winter?
Summer electricity bills are typically 50-60% higher than spring/fall due to AC usage in Texas heat (100°F+). A 2,000 sqft home: Spring ~$120/month electric, Summer ~$200-250/month, Winter ~$130-150/month (less AC but some heating).
What happened during Winter Storm Uri?
In February 2021, extreme cold caused massive power grid failures. Customers on variable-rate plans received bills of $5,000-17,000 for a single month as wholesale prices spiked to $9/kWh. This led to new regulations — always choose fixed-rate plans for predictability.
Should I choose a fixed or variable rate?
Fixed-rate is strongly recommended for most Texans — it protects you from price spikes during extreme weather (both summer heat waves and winter storms). Variable rates may be cheaper in mild months but carry extreme risk. After Uri, most experts advise against variable plans.
How do I compare electricity providers?
Use powertochoose.org (the official PUCT comparison tool). Look at: the average price at 1,000 kWh usage, contract length, early termination fees, and whether the rate includes TDU delivery charges. Many plans advertise low rates that exclude significant fees.
