The September 8, 2023 storms cut power to as many as 125,000 across the metroplex overnight, and Oncor said the worst of it was in Tarrant County.

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.
Oncor and the Tri-County Electric Cooperative are both certificated to serve parts of Keller, subdivision by subdivision; the city itself says many residents sit in an area served by both. Oncor customers choose a retail provider; Tri-County members do not.
The City of Keller Building Services office takes every permit through its online CSS portal and no longer accepts paper applications. Grasten pulls the permit with a licensed electrician and schedules the inspections.
Atmos Energy's Mid-Tex Division runs the gas mains in Keller. Streets without a main use a propane tank.

Why Keller Chooses Grasten
What Makes Us Different
Multi Brand Dealer
If your Keller HOA requires architectural approval, sound and looks matter. Kohler runs a few decibels quieter than the rest, Generac is the most widely installed, and Cummins handles heavier loads. We carry all four brands and prepare the HOA application for you.
Four Brands, One Recommendation
12 Year Power Plus Warranty
Some Keller subdivisions get power from Oncor, others from the Tri-County Electric Cooperative. Either way, the 12-Year Power Plus Warranty covers parts, labor, travel and major components on Generac air-cooled units at no extra cost, exclusive to Canter Power Systems brands.
12 Years of Full Coverage
Customized Mobile Fleet
The September 8, 2023 storms cut power to as many as 125,000 across the metroplex, and Oncor said Tarrant County took the worst of it. Our remote monitoring flags fault codes the moment they post, so a tech heading to Keller knows what to bring.
Ready to Roll
Typically 30 to 90 days from estimate to power on, depending on City of Keller permit timelines. Grasten pulls the permit with a licensed electrician and schedules the inspections. See all six differentiators and the full process on the Fort Worth page ›
Keller Pricing
What Does a Generator Cost in Keller?
Installed in the Fort Worth area, a whole home generator runs $7,000 to $25,000+. Here's where most Keller 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 Keller 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
Keller Generator Questions, Answered
Do I need a permit to install a generator in Keller?
Yes. The permit comes from City of Keller Building Services at Town Hall, 1100 Bear Creek Parkway, applied for through the city’s online CSS portal; the city no longer accepts paper applications. Tarrant County issues no building permits for single-family homes outside city limits. Grasten pulls the permit with a licensed electrician and schedules the inspections.
What knocks out power in Keller?
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. Winter Storm Uri in February 2021 left around 172,000 Oncor customers in Tarrant County without power on the afternoon of February 16, many for days in subfreezing cold. The May 28, 2024 storms still had 13,500 Oncor customers in Tarrant County without power at 10 p.m., out of more than 650,000 across North Texas that day. A standby generator starts on its own within seconds and runs until your utility restores service.
Is natural gas available at my Keller address?
Often, yes. Atmos Energy serves Keller. 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 Keller 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 Keller for repairs?
Keller is served from our Dallas facility at 10840 Sanden Dr B, about 37 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.
