How Much Does Generator Installation Cost in Dallas, TX?
A 22 kW whole-house generator costs $8,000 – $13,000 installed in Dallas (close to the Texas average — Dallas has a competitive installer market with lower labor costs than coastal cities).

Dallas doesn't get hurricanes, but Winter Storm Uri in 2021 was worse than most hurricanes for the DFW metro. Over 2 million homes lost power in sub-freezing temperatures for up to 5 days. Pipes burst, homes flooded, and the damage was catastrophic. Since then, generator sales in Dallas have surged. Oncor distributes power in the DFW area, but ERCOT's isolated grid means Texas can't import power from neighboring states when demand exceeds supply.

Permits
Permit cost: $100 – $275. Timeline: 1-2 weeks. Your installer handles filing and inspection.
Preferred Fuel: Natural Gas
Atmos Energy serves most of the Dallas metro with cheap, abundant natural gas. Texas gas infrastructure stayed operational during Uri even when the electric grid failed.

FAQ — Generator Installation in Dallas
How much does a 22 kW generator cost in Dallas?
A 22 kW generator costs $8,000-$13,000 installed in Dallas. The DFW metro has strong installer competition, keeping prices close to the Texas average.
Will my generator protect me during another winter storm like Uri?
Yes. A natural gas standby generator runs independently of the ERCOT grid. During Uri, natural gas supply held up in most DFW areas even when electricity failed. Your furnace, lights, and refrigerator stay on.
Does Dallas have tornado risk too?
Yes. The DFW metro sits at the southern edge of Tornado Alley. North Texas gets 15-20 tornado warnings per year on average. Tornadoes cause sudden, localized power outages with no preparation time.
