Start with the utility service area, not the city label
At an eligible Haltom City address, delivery and retail are separate jobs. Oncor Electric Delivery is responsible for the delivery system; the chosen REP supplies the contract terms, energy price and product features. That separation explains why two neighbors can buy different plans while both rely on the same local wires and outage crews.
Do not infer the utility solely from the ZIP code. Start with the exact meter location, confirm Oncor Electric Delivery, and only then filter retail offers. This order prevents a rate comparison from including products that cannot be activated at that Haltom City premise.
