- Mailing cities on the 2,990 competitive home meters in 76657, McGregor's main ZIP code: Mcgregor 2,322, Waco 668.

- Coverage gap: 76657, home to 2,322 McGregor-addressed meters, has 0.66 ERCOT meters for each household the Census counts there.

Co-op homes stay off the competitive market unless their co-op opts in.
