Oncor stays the wires company after a switch
For an Oncor-served Irving property, changing from one REP to another changes the retail agreement, not the distribution infrastructure. Oncor remains responsible for poles, wires, the meter and local outage restoration. The REP competes on price structure, contract terms, billing and service. Use Oncor electricity rates and delivery charges to understand the non-competitive delivery portion. Keeping that component visible prevents a misleading comparison where one REP appears more expensive simply because the TDU charge was omitted from another offer.
