The standard
Backup power held to the standard of the home it protects.
Most systems are sized to keep a few lights on. In a Colleyville home, that isn’t backup — it’s a compromise. We design for the whole house.
A battery sized to run central AC, not just the fridge
Sized to run central AC through a triple-digit Texas afternoon — not just the fridge and a few lamps. Your home stays exactly as it was.
Silent, and entirely automatic
No generator noise, no fuel to store, no switch to flip. The system takes over the instant the grid fails and hands back the moment it returns — you may never notice.
A single point of accountability
One vetted installer manages everything — design, the City of Colleyville permit, Oncor interconnection, inspection and commissioning. You approve; we handle the rest.
Built for this grid
Why Colleyville homes need battery backup on the Oncor grid.
Colleyville sits in Oncor territory in Northeast Tarrant County, on the same North Texas grid that lost power for days during the February 2021 winter freeze and now faces repeated summer conservation appeals as ERCOT’s reserve margins tighten. Outages here are usually short — but they arrive on the coldest and hottest days, when losing power matters most.
The homes make the calculation different, too. Colleyville’s houses are large — frequently 3,500 to 6,000-plus square feet, often with two air-conditioning systems. Backing that up properly isn’t a single battery keeping a lamp on; it’s a system of two or three batteries sized to carry real central-AC load. That’s the difference between a house you’re enduring during an outage and a home that simply carries on.
We design for that reality specifically — matching capacity to your home’s measured load, and handling the permit and Oncor interconnection that any grid-tied battery in the city requires.

Why Colleyville homeowners plan ahead
Questions
Colleyville home battery questions, answered.
How much does whole-home battery backup cost in Colleyville?
A true whole-home system that runs central air conditioning is roughly $25,000–$40,000+ installed for the larger homes common here; an essentials-only system is closer to $12,000–$15,000. Those are planning ranges, and your consultation replaces them with a fixed written quote. The federal residential tax credit ended December 31, 2025, so 2026 systems are quoted without it.
How many batteries do I need to run my whole house?
It depends on your square footage and your central AC load, not a rule of thumb. A large Colleyville home running one or two AC compressors through a summer afternoon usually needs two to three batteries; a home backing up only essentials needs one. We size to your home’s actual measured load during the consultation rather than guessing.
Do I need a permit, and who handles the Oncor paperwork?
Yes — and none of it is yours to file. Your installer handles the City of Colleyville permit, the Oncor interconnection agreement, inspection scheduling and final commissioning. You approve the design and we manage the paperwork.
Is a battery better than a standby generator?
Neither is better in the abstract — it depends on how long your power actually goes out. A battery is silent, fuel-free and instant, which suits the short outages seen here; a standby generator outlasts any battery in a genuine multi-day event, but is louder, burns fuel and needs servicing.
How long does installation take?
Most installations are completed in one to two days on site once the permit is approved. From first consultation to a commissioned system is typically a few weeks, most of which is permitting and the Oncor interconnection rather than the install itself.
