Is Garland Power & Light the utility in Mesquite or Sunnyvale?
Not for the addresses in ERCOT’s extract: all 56,105 active residential meters with a Mesquite or Sunnyvale address are on Oncor’s system. Garland Power & Light is Garland’s city-owned utility and does not offer retail choice; part of ZIP 75150 lies in Garland, so check your address.

No. The delivery utility, Oncor, keeps the same wires and still delivers the electricity, and its delivery charges still appear on your bill. Switching changes the retail provider that bills you, not the wires.
