- On October 5, 2026, ERCOT showed 248 home meters switched off (de-energized) in the ZIP codes most Kaufman homes use, against 2,524 switched on; that 8.9 percent is mostly vacant houses and apartments between occupants. (Source: https://www.ercot.com/misapp/GetReports.do?reportTypeId=203)

- Mailing cities on the 2,524 competitive home meters in 75142, Kaufman's main ZIP code: Kaufman 2,450, Oak Grove 72. 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: 75142, home to 2,450 Kaufman-addressed meters, has 0.36 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 2 co-ops, such as the Trinity Valley and Farmers co-ops. Co-op homes stay off the competitive market unless their co-op opts in.
