Can I choose an electricity provider if I live in Austin?
Not if Austin Energy serves your address. Austin Energy is the City of Austin’s utility and does not offer retail choice, so this page lists no City of Austin ZIP code. Round Rock (72,407 active residential meters in ERCOT’s extract), Pflugerville (41,772) and Hutto (23,298) are on Oncor’s system. A few homes near the Austin city line use an Austin mailing address but are on Oncor; your service address decides.
Do the wires or the delivery utility change if I switch providers?
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.
