Oncor is Grand Prairie's electric delivery utility (Transmission and Distribution Utility) within ERCOT's deregulated electricity market. Oncor owns the wires and meters; your retail electricity provider handles billing. For service-entrance work, capacity upgrades, or solar interconnection, Oncor (1-888-313-4747 / oncor.com) is the correct contact regardless of who sends your monthly bill. Start Oncor contact the same day as the city permit application — utility scheduling adds 2–5 weeks. Atmos Energy (1-888-286-6700) handles natural gas separately.
Grand Prairie's residential housing stock spans from 1960s and 70s ranch homes in the city's older central neighbourhoods to newer construction near the southern and western growth areas. Homes built before 1990 commonly have 100A service panels from that era's standard. EV chargers (which draw 7–11 kW continuously on a 50A circuit) and cold-climate heat pump systems added to an older 100A panel can push capacity limits. A TDLR TECL electrician should assess panel capacity before adding high-draw circuits to any pre-1990 Grand Prairie home.
