Generator Installation Cost in St. Tammany Parish
Straightforward Northshore pricing for turnkey whole home standby installs and what homeowners actually pay in St. Tammany Parish, not a national catalog average.
Typical turnkey cost for a 22kW Generac Guardian
A 22kW Generac Guardian (model G0070420) fully installed with an automatic whole home transfer switch in St. Tammany Parish typically runs between $11,500 and $14,000. That range assumes a standard gas meter location, a reasonable pad setback, and a single family home without a major electrical service upgrade.
The biggest swing factor on the Northshore is usually the gas line run. Homes where the meter sits far from the generator pad, or where trenching must cross driveways and landscaped easements, land toward the upper end of that band.
