Katy, TX — Fort Bend / Harris County

Katy Loses Power. A Lot. Be Ready.

New construction in Katy doesn't mean reliable power. Grid stress, summer heat, and afternoon storms hit this corridor hard every year.

Your home, your math

See the math for your Katy home

Katy sits at the edge of two utility territories, and rapid growth hasn't been matched by infrastructure investment. High-demand summer months push the grid to its limit — and neighborhoods in the 77449, 77450, and 77494 zip codes feel it regularly.

HOA-heavy developments mean noise ordinances matter. A natural gas standby generator runs quieter than a portable, doesn't require fuel storage, and starts automatically before you've finished wondering if the power's out.

What a Katy Family Actually Needs During an Outage

Total Storm Draw
~475 W sustained
The smart panel sheds AC compressor startup and heavy motor surges automatically. This is the spike-free baseline.
Summer Storm · Windows Open
54hrs
27 kWh at 500W sustained. Zero recharging. Absolute worst case. The real experience is you never get close.
Winter Storm · Gas Heat Running

The Gap Is Just Houston.

Maybe the grid doesn't come back until Friday. Maybe you run low Wednesday night and you're without power until Saturday morning.

That gap — Wednesday to Saturday — is just Houston. Everyone who grew up here lived through that gap with nothing. No battery. No generator. Just dealing.

The difference is you got to Wednesday in comfort instead of suffering from Sunday night.

Sun
Storm hits
Grid goes down. Battery kicks in instantly. Fridge running, Wi-Fi up, phones charging.
Mon
Still out · Battery comfortable
Storm normal in effect. Porch life. Grilling what's in the freezer. Neighborhood has a different energy.
Tue
Day two · Still running
54-hour floor means you're still comfortable. Time to assess calmly. No scramble. No 2am decisions.
Wed+
The gap arrives
This is Houston doing what Houston does. You've lived through this your whole life. The difference is you had two days of dignity first.

New house. Old grid. Not your problem anymore.

Why standby power

No HOA approval needed

Many Katy HOAs require ACC approval, sound barriers, and rear-yard placement for generators. A wall-mounted battery has nothing to object to.

No manual startup

Automatic transfer switch monitors grid 24/7 and switches over without you doing anything.

Built for heat season

Keeps essentials running through summer outages — fridge, fans, Wi-Fi, phones — without the fuel cost or noise.
