## Questions
**Does Mexia have electricity choice?** Most Mexia homes can. ERCOT's October 5, 2026 extract has 4,406 Mexia-addressed homes on Oncor's competitive system, compared with 2,598 households in the Census survey. No Mexia ZIP code carries a split flag, but only an address lookup is certain.
**Which Mexia ZIP code has the most homes on the competitive market?** That is 76667, home to 4,393 of the competitive meters with a Mexia address. ZIP-wide: 4,394 ERCOT meters, about 4,036 Census households, 1.09 per household.
**What is the average electricity rate in Mexia?** On October 19, 2026, the median fixed-rate Power to Choose listing on Oncor's wires was 13.4¢ per kWh at 1,000 kWh a month (170 listings); Oncor's delivery charge of 6.8673¢ per kWh plus $4.06 a month is included. A median is not a quote.
**I'm moving to Mexia. How do I set up electricity?** Confirm the address is on Oncor's wires, then pick a plan and a start date. In 76667, 10.8% of residents moved in the past year (ACS); 16 meters in 76667 went vacant-to-active Oct. 7-18, 2026.
**Why are there more electric meters than households in Mexia?** 4,406 Mexia-addressed meters against 2,598 city households is 1.7 per household: the Mexia postal area extends past city limits, and new homes get meters before the Census counts them. It doesn't mean every nearby address can choose.
**Where do I report a Mexia power outage?** Call Oncor (oncor.com/outages), the wires utility for Mexia's 4,406 competitive homes; a retail provider can't fix lines.
