Generator Installs for Houston Area Buildings
When the grid drops, your business should not. Solivance Electric installs commercial standby generators from 22 kW single-phase through 150 kW three-phase — medical suites, warehouses, multi-tenant offices, retail pads, and high-end residential across Greater Houston. Every install starts with a load calc against metered demand, not a sales-sheet guess. Generator siting accounts for exhaust clearance, noise to the nearest property line, refueling access, and the concrete pad spec the manufacturer actually called for. The Automatic Transfer Switch is wired, mechanically interlocked where required, and commissioned with a live grid-drop test. The first annual service date is on the calendar before we leave.
Sized to the metered load, sited on a proper pad, fuel planned for the longest outage on record. ATS wiring and live commissioning on every build.
What's included
- Commercial standby installs from 22 kW through 150 kW
- Automatic transfer switch wiring and commissioning
- Load calc, fuel sizing, and annual maintenance intervals
- Concrete pad, fuel line, and emissions permit handling
“I definitely recommend Solivance Electric to anyone looking for a great, honest electrician. I cannot say enough good things about this company. After being without power for two days after Hurricane Beryl, we reached out wanting a generator interlock installed. Solivance Electric came out that very same day — they had worked through the night to get to everyone else needing the same. They made it clear they were prioritizing homes with children and pets. Aside from the interlock, they found other issues in the panel that could have caused a fire. These are my go-to guys from here on.”
How it works
We read 12 months of metered demand, not a nameplate total, and size the gen-set to actual peak plus a motor-starting safety factor.
Pad location, exhaust and intake clearances, fuel source (natural gas vs diesel vs LP), and refueling access designed before a hole is dug.
Concrete pad to manufacturer spec. Generator set, leveled and anchored. ATS wired and mechanically interlocked. Gas line sized and pressure-tested.
Pricing
A 22–35 kW commercial standby generator install typically runs $14,000–$28,000 turnkey (unit, ATS, pad, gas line, commissioning). 48–80 kW units run $28,000–$60,000. Larger 125–150 kW commercial gen-sets with paralleling or larger ATS builds push past $85,000. Fuel infrastructure, service-entrance upgrades, and enclosure selection (sound-attenuated, weather-protective, level 2) are the biggest variables.
Timeline
Most commercial standby installs are 2–5 working days on site once the gear is delivered: pad cure, gen-set set, fuel line run, ATS wired, commissioning, and final inspection. Equipment lead time adds 4–12 weeks depending on the manufacturer and size. Permits sit inside that window — not after it.
Code & permits
Commercial standby gen-set work in Greater Houston touches NEC Article 702 (optional standby systems) and 700 where the gen-set is backing life-safety or emergency loads. Fuel installations are reviewed against NFPA 37 (stationary combustion engines) and local fire-marshal notes. For natural-gas feeds, CenterPoint Energy gas-side capacity and metering is confirmed ahead of install.
