Whole-House Generator Cost in Texas (2026)
What a standby generator costs to install in Texas, why, and how much you actually need one — from wage data, utility reliability reports and the national cost surveys.
Why Texas homes lose power: Gulf-coast hurricanes, summer heat-driven demand peaks, and winter storms on the state's isolated ERCOT grid (Winter Storm Uri, February 2021) are the dominant causes of sustained outages.
Installed cost breakdown for Texas
Texas's electricians earn $28.50 an hour on average — 17% below the national mean of $34.37. Labor-dependent lines below are scaled accordingly; equipment and permits are not.
| Line item | Low | High |
|---|---|---|
| Generator unit (14-26 kW air-cooled) | $3,500 | $8,000 |
| Automatic transfer switch | $500 | $1,500 |
| Concrete or composite pad | $250 | $500 |
| Electrical work (wiring, panel, conduit) | $1,250 | $2,500 |
| Gas line / propane connection | $400 | $1,250 |
| Permits and inspection | $200 | $500 |
| Installation labor | $850 | $1,650 |
| Total installed | $6,950 | $15,900 |
Labor-dependent lines (pad, electrical, gas connection, installation) are scaled by Texas's electrician wage index of 0.83 versus the national mean. Equipment and permit lines are not scaled.

How often the power goes out in Texas
Average minutes without power per customer per year, excluding major storm days, as reported by Texas utilities to the U.S. Energy Information Administration. In 2024, Texas ran 12% above the national figure of 130 minutes. These figures are the baseline — hurricanes, ice storms and other major events come on top.
Reliability by utility
The state average hides a lot. These are Texas's largest utilities by customer count and what their own reports say about outage minutes and frequency in 2024.
| Utility | Customers | Minutes out / yr | Outages / yr |
|---|---|---|---|
| CenterPoint Energy | 2,847,806 | 150 | 1.62 |
| City of San Antonio - (TX) | 938,905 | 62 | 1.08 |
| AEP Texas Central Company | 913,164 | 150 | 1.46 |
| Austin Energy | 557,039 | 76 | 0.87 |
| Entergy Texas Inc. | 526,491 | 305 | 2.05 |
| Pedernales Electric Coop, Inc | 425,109 | 57 | 0.79 |
Without major event days. A utility with high minutes but few outages has long restorations; many short outages point to a fragile distribution network — either case is what a standby generator is for.
Permits in Texas
Nearly every Texas municipality requires an electrical permit and usually a gas or mechanical permit. Fees are set locally; your installer pulls them and the inspection is part of the job. What the permit and inspection cover →
