Why Goodlettsville Homeowners Act
Goodlettsville rides on the NES grid, and that grid has had a rough run. About 230,000 NES customers were dark at the height of the January 2026 ice storm, the most at one time in the utility's history. The December 2023 tornado left roughly 48,000 NES customers without power, with Goodlettsville among the hardest hit areas, and the May 2020 derecho reached 131,709.

Nashville Electric Service is the utility the city lists. Some Sumner side addresses may be on Cumberland Electric; your bill settles it.
The city's Codes office on North Main Street starts the permit. Electrical goes to Metro Codes on the Davidson side and the State inspector on the Sumner side. GenerX pulls the permit with a licensed electrician.

Goodlettsville Pricing
What Does a Generator Cost in Goodlettsville?
Whole home installs in the Nashville area typically run $7,000 to $25,000+. Here's where most Goodlettsville homes land.
Essential circuits (lights, fridge, AC unit)
Most homes under 3,000 sq ft (full house)
Larger homes, multiple HVAC zones
Large homes, home offices, medical equipment
Prices include equipment, in-house installation, transfer switch, permit fees, and our 12-year warranty on every Generac air-cooled unit we install. Spire Tennessee gas, formerly Piedmont, fuels the unit where a main reaches the house; propane fills in elsewhere.
Because GenerX employs all labor in-house, we eliminate the third-party markup that drives up installation costs elsewhere. Our buying volume across the Canter Power network means better equipment pricing than smaller dealers. The result: a higher-quality installation at a more competitive price, not a trade-off.

Frequently Asked Questions
Goodlettsville Generator Questions, Answered
Why does my side of the county line matter for the permit?
Because the electrical permit comes from a different office on each side. The city’s Codes and Building Safety office at 318 North Main Street takes the city side of the job; Davidson County addresses then take their electrical permit from Metro Nashville Codes, and Sumner County addresses from the State electrical inspector in Hendersonville. GenerX pulls the permit with a licensed electrician and schedules the inspections.
Does Goodlettsville have its own generator permit type?
Yes. City permit reports list a Residential Mechanical generator permit, so a standby unit is permitted as a job of its own.
How bad were NES outages around Goodlettsville?
Large. The December 2023 tornado left about 48,000 NES customers without power, and Goodlettsville was one of the areas with the most outages. The January 2026 ice storm then took out about 230,000.
Will a Goodlettsville HOA want plans first?
If it reviews exterior equipment, yes. We prepare the drawing, sound sheet and screening plan for you.

Our nearest facility, which stocks parts at our local facility. Call any hour for emergency repair; in a big outage, crews from around the state join in.
