Confirm who serves the meter first
Oncor Electric Delivery operates the local distribution network for a verified Keller premise in its territory. The company maintains meters, poles and wires and coordinates restoration after a local distribution outage. A retail electricity provider handles the energy contract and billing relationship. Changing REPs changes the retail agreement, not the physical grid serving the home.
Because certified boundaries can cut across ZIP codes and municipal limits, verify the full Keller address before treating an online offer as enrollable. A latest bill, ESI ID or utility lookup is stronger evidence than the mailing-city name. This is especially important around new subdivisions or edge-of-city developments.
