Provider vs provider.The honest math.
Voltcheckr compares every major Texas electricity retailer in the matchups you actually search for. No fluff, no gimmicks — just which one is really cheaper at your usage.
Texas's two biggest retailers compared side by side — does brand matter when both price-match?
The two retailers that consistently advertise the lowest rates in Texas — and the bill credit thresholds you have to hit to actually get them.
Both are owned by NRG Energy after the 2021 acquisition — but they price very differently. Here's which sibling wins on actual cost.
Both sell 100% renewable energy — one has 25 years of brand trust, the other has a modern app and no phone queue. Which is cheaper?
TXU bets on brand awareness. Gexa bets on the lowest advertised rate. One is almost always cheaper — here's which.
Both are Dallas-based. 4Change chases the cheapest advertised rate via bill credits. Cirro prices flat. Which model wins for your household?
Reliant bundles Nest thermostats and free nights. Gexa chases the absolute lowest rate via bill credits. One of them is almost always cheaper — and it's not the one with the fancier marketing.
TXU has been Texas's biggest electricity brand since 1882. 4Change launched in 2011 and consistently undercuts them. Here's how much brand loyalty actually costs you.
Both sell renewable energy. Rhythm does it with a modern app and flat pricing. Gexa does it with aggressive bill credits. Which approach actually saves you money?
Neither uses bill credits. Neither bundles smart home devices. Both just sell straightforward fixed-rate electricity. Which one is cheaper?
Houston has longer summers and higher usage. Dallas has more stable winter rates. Here's how the electricity math shakes out for each city.
Dallas is fully deregulated with 200+ plans to shop. Austin city limits are served by a municipal utility with zero choice. Surrounding suburbs can still shop.
Houston is 100% deregulated. San Antonio's city limits are locked to CPS Energy with no shopping. The surrounding AEP Texas territory can shop freely.
Dallas and Fort Worth are both served by Oncor. Every retail plan available in Dallas is available in Fort Worth, at the same rate. There's no electricity-based reason to prefer one over the other.
