Power Outage Profile
The local details that shape your install: who runs the grid, who issues the permit, and which gas partners are in your area.
Denton Municipal Electric, the city-owned utility, serves about 72,000 customers inside the city and runs its own outage map. DME customers are not in the retail-choice market; CoServ and Oncor serve the surrounding county.
The City of Denton Development Services Building Safety Division issues the permit through its eTRAKiT portal, which also takes inspection requests and fees. Grasten pulls the permit with a licensed electrician and schedules the inspections.
Atmos Energy's Mid-Tex Division runs the gas mains in most of Denton; CoServ Gas serves part of the city. Streets without a main use a propane tank.

Why Denton Chooses Grasten
What Makes Us Different
Multi Brand Dealer

In Denton, we file the permit with the Building Safety Division through eTRAKiT, then install the generator ourselves, with no subcontractors. Each Generac air-cooled install carries the 12-Year Power Plus Warranty, exclusive to Canter Power Systems brands and covering labor, travel and parts.
12 Years of Full Coverage
Customized Mobile Fleet

Denton Pricing
What Does a Generator Cost in Denton?
Installed in the Fort Worth area, a whole home generator runs $7,000 to $25,000+. Here's where most Denton 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, City of Denton permit fees, and our 12-year warranty. Where a Atmos gas main reaches your street, a natural gas connection typically adds minimal cost compared with a propane tank installation.
Because Grasten Power installs with our own crews instead of subcontractors, we cut out the outside markup that pushes installation costs higher at other companies. As a multi brand dealer, we match you with the unit that fits your home and budget rather than the only one on the shelf. The result is a higher quality installation at a fair price.

Frequently Asked Questions
Denton Generator Questions, Answered
Do I need a permit to install a generator in Denton?
Yes. The permit comes from City of Denton Development Services, Building Safety Division, at 401 North Elm Street, applied for through the city’s eTRAKiT portal, which also handles inspection requests and fees. A Denton address outside the city limits goes through Denton County Development Services on Morse Street in Denton. Grasten pulls the permit with a licensed electrician and schedules the inspections.
What knocks out power in Denton?
Spring and summer storms with straight-line wind and hail, the occasional tornado, and the kind of winter event that took the ERCOT grid down statewide. The May 28, 2024 storms cut power to about 9,000 Denton Municipal Electric customers at the peak, with straight-line gusts over 80 mph measured in Denton, and 582 homes and businesses were still out that evening. Winter Storm Uri in February 2021 left about 28,000 Oncor customers in Denton County without power on the afternoon of February 16. A standby generator starts on its own within seconds and runs until Denton Municipal Electric restores service.
Is natural gas available at my Denton address?
Often, yes. Atmos Energy serves Denton for most addresses, with CoServ Gas on part of the city. Where there is no gas main on your street, the generator runs on propane from a tank on your property. We confirm which applies during the free estimate.
Will my Denton HOA allow a whole home generator?
Many HOAs require architectural approval before installation. Grasten Power prepares the application package and goes through the review process for you, so you are not chasing board approvals on your own.
How fast can Grasten reach Denton for repairs?
Denton is served from our Dallas facility at 10840 Sanden Dr B, about 41 miles away. Our service vehicles are built out for first visit repairs and stocked with the parts that come up most, and our dispatch runs 24/7 with a live phone.
