Katy, TX
Battery backup for Katy homes and businesses
Katy is one of the fastest-growing suburbs in the Houston metro. New neighborhoods mean modern homes and a growing commercial corridor, but they all connect to the same CenterPoint network that has struggled through multiple major outages. Eos Backup and Battery installs battery systems that protect homes and businesses automatically.
New homes, same grid vulnerabilities
Katy has grown dramatically over the past decade. Subdivisions like Cinco Ranch, Grand Lakes, and LaCenterra continue to expand westward. Many homes are relatively new, which means updated electrical panels, modern wiring, and smart home systems. But all of them connect to the same ERCOT grid and the same CenterPoint distribution network that has failed during hurricanes, winter storms, and summer heat events.
After Hurricane Beryl in 2024, Katy homeowners were among the hundreds of thousands who waited days for power to return. Local retailers, restaurants, and medical offices closed alongside them, losing inventory and revenue while the grid recovered. A battery system would have meant the difference between a normal week and a displaced family, or between staying open and shutting the doors.
The good news is that modern Katy homes are ideal candidates for battery installation. Standard 200-amp panels, two-car garages with available wall space, and single-family construction make for clean, efficient installs. Commercial buildings in the area, from strip retail to single-tenant offices, are typically just as straightforward once we review the load profile.

Battery backup for Katy businesses
Katy commercial growth tracks its residential growth. Retail at LaCenterra and Cinco Ranch Avenue, medical and dental offices across Cinco Ranch and Grand Lakes, restaurants along the I-10 corridor, and small professional offices in Old Katy all share the same CenterPoint feeders that fail during major weather events.
Retail and restaurants
Keep refrigeration, point of sale, and lighting running through outages so you do not lose perishable inventory or have to close mid-shift.
Medical and dental offices
Protect imaging equipment, sterilizers, refrigerated medications, and electronic health records during grid disturbances. No noisy generator outside the lobby.
Professional offices
Keep servers, payment systems, and HVAC online so staff can keep working when the grid blinks. Silent, automatic switchover within milliseconds.

Common questions from Katy homes and businesses
Do you serve all Katy subdivisions, including the newer ones west of 99?
Yes. We install throughout Katy including the fast-growing communities west of the Grand Parkway, such as Cane Island, Jordan Ranch, and Elyson. These newer subdivisions are well-suited for battery installation thanks to modern panels and accessible garage layouts.
How does Fort Bend County permitting work for Katy battery installations?
Katy spans both Harris and Fort Bend counties depending on the specific address. Our team determines the correct jurisdiction for your property and handles all permitting, whether that is through the City of Katy, Harris County, or Fort Bend County. We also manage the CenterPoint interconnection notification required for all battery installations in their territory.
My Katy home has a large AC unit. Can a battery system handle it?
Yes. The Sigenergy system we install delivers 17.1 kW of peak surge capacity from a single inverter, which is enough to start a 3-ton central AC compressor without stacking units. Many competing systems require two inverters to achieve the same result. If your home has multiple large AC zones, we size the system during the site assessment to ensure it handles your specific equipment.
How long does installation take in Katy?
The physical installation takes one to two days. Permitting adds two to four weeks depending on the jurisdiction. Once permits are approved, our team schedules the installation around your availability and typically completes it in a single visit. We let you know exactly what to expect at each stage before we begin.
Do you install battery systems for businesses in Katy?
Yes. We install commercial battery storage for Katy businesses including retail at LaCenterra and Cinco Ranch Avenue, medical and dental offices across Cinco Ranch and Grand Lakes, restaurants along the I-10 corridor, and small professional offices in Old Katy. Commercial systems are sized to the building load profile and quoted per project. See our commercial solutions page for details on monitoring, peak shaving, and continuity engineering.
