Who do I call when the power goes out?
Call Oncor at 888-313-4747 or use oncor.com outage tools. Your REP does not restore wires or poles. If your bill shows Austin Energy, PEC, or Bluebonnet, use that provider instead.

Who provides natural gas, and what if I smell gas?
Atmos Energy Mid-Tex is the typical LDC for many Round Rock 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.
