Colleyville sits in a sweet spot—literally and figuratively. Tucked between DFW Airport and Grapevine, close to everything but insulated from the noise. GCISD schools. Established neighborhoods with mature trees. Homes that were built to last, not to flip. Median home values around $850K reflect a community that values substance over flash.
Here's Colleyville's backup power advantage: most homes here have natural gas service. That means a standby generator connects to an existing gas line, runs indefinitely during an outage, and costs less to install than in neighborhoods that need propane tanks. If your home is in the Montclair, Caldwell Creek, or L.D. Lockett area, you've probably already got the infrastructure for a generator. It's just sitting there, unused.
Colleyville homeowners have dealt with enough DFW weather to know the pattern. Summer storms roll through from the west, the power blinks, and you're resetting every clock and smart device in the house. Sometimes it's twenty minutes. Sometimes it's twelve hours. The unpredictability is the problem. And with ERCOT's reserve margins thinner than anyone's comfortable with, the question isn't if you'll lose power again. It's when.
What's at stake during an outage:
Home offices, pool equipment, security systems, and the HVAC keeping 3,000–5,500 square feet comfortable. Most Colleyville homes have natural gas—making generator installation straightforward and eliminating the propane tank question entirely.
What's popular in Colleyville: Natural gas standby generators are the top pick in Colleyville. With most homes already connected to gas service, installation is simpler and more cost-effective than in many other suburbs. That said, battery interest is growing—especially among homeowners who've recently added solar panels or want the silent, instant switchover that batteries provide.

Colleyville sees multiple outage events per year, primarily during spring and summer storm seasons. The DFW metroplex has seen outages increase 35% over five years.

If your Colleyville home has natural gas (most do), a standby generator offers the best value—indefinite runtime, lower installation cost, and whole-home coverage. If you value silent operation, want the 30% federal tax credit, or have solar panels, battery backup is the better fit. Some homeowners opt for both: battery handles the seamless switchover, generator provides unlimited runtime.
