Midlothian 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 lines in part of Midlothian and the HILCO Electric Cooperative serves the rest, by area; the city routes outage reports to whichever serves your address. Oncor customers choose a retail provider; HILCO members do not.
The City of Midlothian Building Inspections Department issues the permit through its MyGov portal, which also takes fees and inspection requests. Grasten pulls the permit with a licensed electrician and schedules the inspections.
Atmos Energy's Mid-Tex Division runs the gas mains in Midlothian. Streets without a main use a propane tank.

Why Midlothian Chooses Grasten
What Makes Us Different
Multi Brand Dealer
A Midlothian house on HILCO Electric Cooperative lines needs the same careful sizing as one on Oncor. Grasten sells four brands, so a large home with heavy loads can get a Cummins, and a tighter budget can start with Briggs & Stratton.
Four Brands, One Recommendation
12 Year Power Plus Warranty
Grasten files the Midlothian permit through the city's MyGov portal, which also books the inspections. From there, a Generac air-cooled generator is protected for 12 years, travel and major components included. Yearly service by a Certified Canter Technician keeps that coverage alive.
12 Years of Full Coverage
Customized Mobile Fleet
The March 8, 2025 storms cut power to nearly 18,000 Oncor customers in Ellis County at the peak. Our vans make the trip of about 39 miles from Dallas built to fix things on the first call, and a real person answers our phone.
Ready to Roll
Typically 30 to 90 days from estimate to power on, depending on City of Midlothian permit timelines. Grasten pulls the permit with a licensed electrician and schedules the inspections. See all six differentiators and the full process on the Dallas page ›
Midlothian Pricing
What Does a Generator Cost in Midlothian?
A whole home generator in the Dallas-Fort Worth metro costs $7,000 to $25,000+, installed. Here's where most Midlothian 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 Midlothian 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
Midlothian Generator Questions, Answered
Do I need a permit to install a generator in Midlothian?
Yes. The permit comes from the City of Midlothian Building Inspections Department at 215 North 8th Street, applied for through the city’s MyGov portal, which also handles fees and inspection requests. A Midlothian address outside the city limits goes through the Ellis County Department of Development in Waxahachie, which has no residential building code or electrical inspection authority. Grasten pulls the permit with a licensed electrician and schedules the inspections.
What knocks out power in Midlothian?
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 March 8, 2025 storms knocked out power to nearly 18,000 Oncor customers in Ellis County at the peak, most of them around Waxahachie and Ennis. The May 28, 2024 storms knocked out power to more than 650,000 Oncor customers across North Texas in one day. A standby generator starts on its own within seconds and runs until your utility restores service.
Is natural gas available at my Midlothian address?
Often, yes. Atmos Energy serves Midlothian. 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 Midlothian 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 Midlothian for repairs?
Midlothian is served from our Dallas facility at 10840 Sanden Dr B, about 39 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.
