- ERCOT's daily extracts logged 11 newly created home meters in the ZIP codes most Heath homes use between Oct. 7 and Oct. 18, 2026; the busiest was 75126 with 7. Another 34 went from vacant to active over the same days. (Source: https://www.ercot.com/misapp/GetReports.do?reportTypeId=203)

- 92 percent of Heath's competitive homes (4,015 of 4,375) are in 75032; counting every address in that ZIP, ERCOT has 1.02 meters for each Census household.

- Mailing cities on the 13,473 competitive home meters in 75032, Heath's main ZIP code: Rockwall 8,792, Heath 4,015, Mclendon Chisholm 606, Fate 60. A mailing city is not a city limit, so the service address, not the postal name, settles which utility serves a home. (Source: https://www.ercot.com/misapp/GetReports.do?reportTypeId=203)
- Coverage gap: 75126, home to 360 Heath-addressed meters, has 0.57 ERCOT meters for each household the Census counts there. That fits co-op service: EIA's 2024 lists for the counties tied to the ZIP include 3 co-ops, such as the Trinity Valley, HILCO, and Farmers co-ops. Co-op homes stay off the competitive market unless their co-op opts in.

## Questions
**Can I choose my electricity provider in Heath?** Yes, where Oncor's wires reach the house, which in Heath is most of the city: 4,385 homes with a Heath mailing address were on the competitive market on October 5, 2026, 1.23 for each Census household. Addresses in 75126 (split) need an exact-address check before you shop.
**Which Heath ZIP code has the most homes on the competitive market?** 75032. It holds 4,015 Heath-addressed competitive homes; counting every address in the ZIP, ERCOT has 13,473 meters for roughly 13,250 households, a 1.02 ratio. The weakest coverage among Heath's ZIP codes: 75126, 0.57.
**Which part of Heath has the highest electric bills?** 75032 has the highest share of $250-plus monthly electric bills among Heath's core ZIP codes (45.2 percent of households, ACS 2020-2024); 75126 has 28.7 percent. Bigger and all-electric homes push the share up.
**How do I start electric service at a new Heath address?** 15.9% of 75126 residents moved within a year (ACS), and 25 meters in 75126 turned from vacant to active Oct. 7-18, 2026. Check that your Heath address is on Oncor's wires, then choose a plan and start date.
**Why does my Heath home have a Rockwall address?** 75032 covers part of Heath, but the Postal Service names most of it Rockwall: that postal city is on 65 percent of the ZIP's 13,473 competitive home meters, Heath on 30 percent. Your mailing city is not your city limits; the service address decides the utility.
**Who do I call in Heath when the power goes out?** Call Oncor (oncor.com/outages), the wires utility for Heath's 4,385 competitive homes; a retail provider can't fix lines.
