Rockwall at a Glance
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 owns the poles and wires in most of Rockwall and restores outages; the Farmers Electric Cooperative serves other addresses, and the city publishes both outage links. Oncor customers choose a retail provider; co-op members do not.
The City of Rockwall Building Inspections office issues the permit through its CityWorks Public Portal, which also takes fees and inspection scheduling. Grasten pulls the permit with a licensed electrician and schedules the inspections.
Atmos Energy's Mid-Tex Division runs the gas mains in Rockwall. Streets without a main use a propane tank.

Why Rockwall Chooses Grasten
What Makes Us Different

Rockwall Pricing
What Does a Generator Cost in Rockwall?
A whole home generator in the Dallas-Fort Worth metro costs $7,000 to $25,000+, installed. Here's where most Rockwall 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 Rockwall 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
Rockwall Generator Questions, Answered
Do I need a permit to install a generator in Rockwall?
Yes. The permit comes from City of Rockwall Building Inspections at 385 South Goliad Street, applied for through the city’s CityWorks Public Portal, which also handles fees and inspection scheduling. A Rockwall address outside the city limits goes through Rockwall County Development Services on East Yellowjacket Lane, which reviews plans and issues permits for the unincorporated county. Grasten pulls the permit with a licensed electrician and schedules the inspections.
What knocks out power in Rockwall?
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 left more than 600,000 Oncor homes and businesses without power at 3 p.m., by the city’s own release, and about 1,800 Rockwall County customers were still out three days later. The February 3, 2022 ice storm left 1,482 customers across Rockwall County without power, 1,181 of them in Rockwall and Royse City. A standby generator starts on its own within seconds and runs until Oncor restores service.
Is natural gas available at my Rockwall address?
Often, yes. Atmos Energy serves Rockwall. 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 Rockwall 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 Rockwall for repairs?
Rockwall is served from our Dallas facility at 10840 Sanden Dr B, about 14 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.
