Texas electricity definition

ERCOT

Also: Electric Reliability Council of Texas

The independent system operator that manages the ERCOT grid and administers wholesale and retail-market functions in its region.

What it means

ERCOT coordinates grid operations and retail-market transactions. It is not a retail provider, and being in the ERCOT region does not by itself prove that a specific address has retail choice.

Eyebiss interpretation

How the decision system uses this concept

Eyebiss treats ERCOT-region facts as market context, not as proof that a household is eligible to switch providers.
