Generator Installation in Dallas, TX
Dallas, TX generator installers serve the broad Metroplex where 2021's Winter Storm Uri permanently changed standby demand. Oncor outages from ice storms, summer ERCOT alerts, and severe thunderstorms drive installs. Most homes go 22–24kW natural gas standby (Generac, Kohler) on Atmos service. Lake Highlands, Lakewood, Preston Hollow, and growing East Dallas neighborhoods are steady install zones.
Oncor is the local TDU; ERCOT retail providers handle billing. Atmos Energy serves most of Dallas. Texas requires a TDLR Master Electrician on the license. Dallas Sustainable Development handles permits — same-week scheduling typical.
Frequently Asked Questions
- Permit required?
- Yes — Dallas Building Inspection requires electrical and gas permits. Your TDLR Master Electrician handles filing.
- After the 2021 freeze — still worth installing?
- Yes. Outages during winter cold snaps and summer ERCOT alerts continue. 22kW natural gas standby is a one-time fix.
- Whole-home 22kW vs essential 14kW?
- 22kW covers whole-home including central AC. 14kW with load management runs essentials. AC matters more in summer; furnace less so given Dallas winters.
- Atmos gas service — line size for a 22kW?
- Most Atmos services have enough capacity. Your installer sizes the gas line from meter to generator and may need to upsize the meter regulator (Atmos handles this).
