Electricity rates in Texas

Not a state average. The same household, priced hour by hour for a year on the default plan at each utility we cover here — so the differences below are differences in the tariffs, not in how much anyone used.

Median and range across the 5 utilities, each on the plan a household lands on by default. Estimates for comparing utilities against each other, not a prediction of any one bill; they exclude taxes, local surcharges and demand charges.

How much does where you live inside Texas matter?

Run the same three-bedroom house with central air through the default residential plan at each of the 5 utilities we cover in Texas, and the yearly bill lands between $992 at City of San Antonio and $1,381 at Entergy Texas; the median is $1,249. That $389 gap is for identical electricity, and it is set by nothing you chose: which utility's territory the house stands in. You cannot switch utilities. What you can do is make sure you are on the right plan at yours.

The utility is fixed by your address; the plan is not. At Denton County Elec Coop, the cheapest and dearest of its 4 comparable plans are $422 a year apart for the same house — about the same as the gap between Texas's cheapest and dearest utilities, and unlike that one, it is a choice you get to make.

4 of the 5 utilities file at least one plan priced by the hour (4 plans in all). If yours is one of them, shifting when you use power is worth real money; if not, only the total matters and the plan list is short.

Texas has retail choice: you can buy the supply half of your bill from a competing supplier while the utility still delivers it. The figures on this page price the utility's own default supply, which is what you pay if you never shopped. A third-party offer replaces only that part — the delivery charges and the fixed charge stay with the utility whatever you sign.

Utility by utility

Cheapest first, for the family home. The last two columns are where the money is: how far the default plan sits from the cheapest one the same utility files.

Default plan is the one a household is put on without choosing; we infer it from the tariff structure, since the source data flags it for only 3% of plans. One utility is listed below but not in this table: every plan there either carries a demand charge we do not price or is not an ordinary household tariff.
