Who do I call when the power goes out?

Who provides natural gas, and what if I smell gas?
Atmos Energy Mid-Tex is the typical LDC for many Elgin addresses (Round Rock city guide lists Atmos). Start 888-286-6700. Suspected leak: leave, then 911 and Atmos 866-322-8667. Austin proper more often uses Texas Gas Service—do not assume TGS in Round Rock.
Is electricity regulated or competitive here?
Oncor: competitive REP choice. Bluebonnet EC: non-competitive. Check ESI ID before Power to Choose.
Does Elgin use Austin, Houston, or Dallas 311?
Do not call Austin 311 for Round Rock/Georgetown/Pflugerville/Hutto/Manor/Elgin/Luling water. Life-threatening emergencies still dial 911.
Which internet providers serve 78621?
Common Austin-metro options include AT&T Fiber, Google Fiber (where built), Spectrum, Astound/Grande, and fixed wireless/5G home internet. Availability varies by building—use each provider’s checker with your full street address. Listing is not a guarantee.
How do I tell Austin Energy / co-op from Oncor competitive wires?
Look at your electric bill logo/payee. Austin Energy and city munis (Georgetown, Luling) bill as the utility (no REP). PEC/Bluebonnet bills are from the cooperative. Oncor delivery shows a separate Retail Electric Provider. Match outage numbers to your bill.
