Generator Installation in Austin, TX

Standby and portable generator installation in Austin — automatic transfer switches, natural gas and propane, permitted.

February 2021’s Winter Storm Uri left millions of Texans — including much of the Austin metro — without power for days to weeks in subfreezing temperatures. That event fundamentally changed how Austin homeowners think about backup power. Arc Nemesis Electric installs both whole-home standby generators (Generac, Kohler, Briggs & Stratton) and portable generator transfer switches, handling the electrical portion of the installation including the automatic transfer switch (ATS), dedicated circuits, and the required City of Austin permit.

Frequently Asked Questions About Generator Installation

ERCOT’s independent grid makes Texas uniquely vulnerable to both extreme cold (Winter Storm Uri, 2021) and extreme heat (rolling conservation alerts in summer). Austin Energy can implement controlled outages during grid stress events. A whole-home standby generator detects power loss within seconds and automatically restores power to your home — keeping refrigerators running, medical equipment online, and homes at livable temperature without manual setup.
A 10–14kW generator powers an average Austin home ’s essential circuits: HVAC, refrigerator, lights, and outlets. A 20–22kW generator powers the full home including a 200A panel home with central AC, electric range, and multiple large loads simultaneously. Larger homes or homes with electric vehicle charging need 24kW+. Arc Nemesis Electric sizes the generator to your actual load profile — not a generic formula.
Natural gas is preferred in Austin neighborhoods serviced by Atmos Energy’s gas distribution system — it runs indefinitely without refueling, which matters during extended outages. Propane is the right choice for areas without natural gas service (common in Cedar Park, Leander, and some Pflugerville neighborhoods). Arc Nemesis Electric works with your gas provider on natural gas line sizing and handles the propane tank coordination for propane installs.
The electrical portion of a standby generator installation — installing the automatic transfer switch, running conduit to the generator pad, and connecting to the panel — takes 1–2 days. The full project timeline including the generator pad, gas line connection (handled by a licensed plumber), and Austin Energy inspection is typically 3–7 business days from permit approval.
Yes. Generator installation in Austin requires both an electrical permit and a mechanical permit. Arc Nemesis Electric pulls the electrical permit and coordinates with your gas plumber on the mechanical permit. The City of Austin inspection is scheduled after installation and Arc Nemesis Electric is on-site for that inspection.
