Oncor and electricity delivery in Plano
For Oncor-served Plano homes, provider choice affects the retail electricity product but not the company maintaining the distribution system. Oncor remains the delivery utility after a REP switch. The plan comparison should therefore separate competitive energy pricing from the regulated delivery charges that still apply at the address. If a distribution outage occurs in Plano, changing the REP does not create a different local grid. The delivery utility remains responsible for restoration, so provider comparisons should focus on the retail contract, billing and customer service rather than imply that each provider owns separate power lines. Why ZIP code and the service address matter. For live shopping in Plano, location needs to be more precise than the city label. ZIP code narrows the market and the full address resolves boundary or eligibility questions. Only plans genuinely available at the property should be shown. This avoids presenting statewide offers that cannot be purchased at the address and keeps delivery charges matched to the correct utility territory.
