What's counted

Medium meter
A business meter whose peak demand over the previous 12 months was 50 kW or more but less than 1,000 kW (16 TAC ยง25.43).
Large meter
A business meter whose peak demand over the previous 12 months was 1 MW or more (same rule).
Active only
Meters marked Active in ERCOT's file. Inactive and de-energized meters are left out.
Utilities in the file
CenterPoint. City-owned utilities and electric co-ops choose whether to join Texas's retail electric market, and meters of those outside it are not in ERCOT's file, so their customers in Harris County are not counted here.
One meter, one count
A business with several meters is counted once per meter, so a campus or tower can add many.

The statewide page explains how meters with a blank county field were placed.
