Magnolia Outage History
Why Magnolia Homeowners Act

On September 22, 2026, a transmission line failure left about 15,000 CenterPoint customers in the Magnolia area without power. Two months before Beryl, the May 16, 2024 derecho had already knocked out more than 900,000 CenterPoint customers in a single evening. Winter Storm Uri in February 2021 left more than 1.4 million CenterPoint customers without power on the night of February 15.

Why Magnolia Chooses Grasten
What Makes Us Different
Multi Brand Dealer
Wooded lots outside Magnolia's city limits often sit beyond the gas main and run on propane, which changes how a generator should be sized. Hearing Generac, Briggs & Stratton and the other two brands side by side in our showroom shows you the difference first.
Four Brands, One Recommendation

Magnolia Pricing
What Does a Generator Cost in Magnolia?
Whole home installs in the Houston area typically run $7,000 to $25,000+. Here's where most Magnolia 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 Magnolia permit fees, and our 12-year warranty. Where a CenterPoint gas main reaches your street, a natural gas connection typically adds minimal cost compared with a propane tank installation.
Most Magnolia homes on city gas service run natural gas. CenterPoint Energy Gas covers most of the metro, and the generator pulls off the same line that already feeds the house.

Frequently Asked Questions
Magnolia Generator Questions, Answered
Do I need a permit to install a generator in Magnolia?
Yes. The City of Magnolia Planning and Permits office issues a dedicated generator permit: the application is emailed to the permits office, the contractor securing it must be registered with the city as a licensed electrical contractor, and inspections are requested through the city’s third-party inspector. Most Magnolia addresses are outside the small city limits and go through the Montgomery County Permit Department in Conroe. Grasten is set up for both and pulls the permit with a licensed electrician.
What knocks out power in Magnolia?
Hurricanes and summer storms on the overhead lines, and the occasional grid failure. When Hurricane Beryl came through in July 2024, 2.26 million CenterPoint customers lost power, the largest outage in the company’s history, and 1.28 million of them were still waiting two days later. On September 22, 2026, a transmission line failure left about 15,000 CenterPoint customers in the Magnolia area without power. A standby generator starts on its own within seconds and runs until CenterPoint restores service.
Is natural gas available at my Magnolia address?
Often, yes. CenterPoint Energy Entex serves Magnolia. 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 Magnolia 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 Magnolia for repairs?
Magnolia is served from our Conroe facility at 10890 TX-242, about 21 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.
