Why Grand Prairie Chooses Grasten
What Makes Us Different
Multi Brand Dealer
Grand Prairie reaches into Dallas, Tarrant and Ellis counties, and the homes here vary as much as the map does. Compare Kohler, Generac, Briggs & Stratton and Cummins side by side in our showroom, hear how each one sounds, then we size the right fit.
Four Brands, One Recommendation
12 Year Power Plus Warranty
We file your permit through the City of Grand Prairie Customer Self-Service portal, then register your Generac air-cooled unit for the 12-Year Power Plus Warranty. Annual maintenance by a Certified Canter Technician keeps it active, and it transfers for a small fee if you sell.

Grand Prairie Pricing
What Does a Generator Cost in Grand Prairie?
A whole home generator in the Dallas-Fort Worth metro costs $7,000 to $25,000+, installed. Here's where most Grand Prairie 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 Grand Prairie 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
Grand Prairie Generator Questions, Answered
Do I need a permit to install a generator in Grand Prairie?
Yes. The permit comes from the City of Grand Prairie Building Inspections Division at City Hall, 300 West Main Street, and every application goes through the city’s Customer Self-Service portal. Grand Prairie reaches into Dallas, Tarrant and Ellis counties, so an address outside the city limits goes through the Dallas County Department of Unincorporated Area Services (permits through the MGO portal), Tarrant County Engineering Services or the Ellis County Department of Development, depending on the parcel. Grasten pulls the permit with a licensed electrician and schedules the inspections.
What knocks out power in Grand Prairie?
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 put more than 340,000 Oncor customers in Dallas County in the dark by noon, and 248,000 were still out at 10 p.m. Across North Texas more than 650,000 Oncor customers lost power that day. A standby generator starts on its own within seconds and runs until Oncor restores service.
Is natural gas available at my Grand Prairie address?
Often, yes. Atmos Energy serves Grand Prairie. 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 Grand Prairie 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 Grand Prairie for repairs?
Grand Prairie is served from our Dallas facility at 10840 Sanden Dr B, about 31 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.
