Commercial generator installation

Commercial standby generators sized, permitted and installed — from the load study through to a commissioned system signed off by the inspector. We work from engineered drawings where a project has them, and produce the electrical scope where it does not.

  • Load study first. Motor starting, non-linear loads from drives and UPS equipment, and planned growth — not a rule of thumb.
  • Automatic transfer switches. Specified to the service and the load, including service-rated and life-safety configurations.
  • Permits and inspections. Pulled and coordinated with whichever authority has jurisdiction over the address.
  • Coordination with GCs and engineers. We read the drawings, attend the meetings, and own the generator-to-distribution interface rather than assuming someone else has it.
  • One licensed contractor. Generator, transfer switch and the electrical work under the same license.

Where commercial differs from residential

Past roughly 26 kW you leave air-cooled equipment behind and move to liquid-cooled units, and the job changes character with it. Three-phase service, larger transfer switches, fuel supply that has to be engineered rather than assumed, and in many cases code requirements around life-safety and egress circuits that do not apply to a house.

Sizing stops being a rule of thumb too. That warrants an actual load study, not a checkbox estimator — the sizing tool on this site is built for homes and will not scope a building.

Generator maintenance contracts

A standby generator is an engine that spends almost all of its life switched off. The weekly self-test proves it starts; it proves very little about whether the machine will carry your building for two days. Equipment that sits unmaintained fails at exactly the moment the grid does — which is the only moment it was bought for.

A planned maintenance contract puts the servicing on a schedule instead of on someone remembering. It also keeps the manufacturer's warranty intact, which requires documented servicing at their intervals on every make.

What a contract covers

  • Scheduled visits. Planned in advance and attended on a set interval, so the date does not move when everyone is busy.
  • Documented results. You get a record of what was checked and what was found — which is what a warranty claim and an insurer both ask for.
  • Repair and warranty service. Kohler and Generac warranty work goes through us, so a claim is not your problem to chase.
  • Priority over non-contract work. Contract customers are scheduled ahead of ad-hoc calls.

Commercial generator repair

Diagnosis and repair on commercial standby generators and automatic transfer switches, whoever installed them. A unit that will not start, will not transfer, alarms on the controller, or starts and then drops the load are all different faults — we work out which before quoting parts.

We hold manufacturer credentials with Kohler and Generac specifically — Kohler Certified and Generac Authorized Dealer — so warranty repair on those two goes through us rather than through you.

Who we work with

Building owners, property managers, facility managers, general contractors and engineers. On a new build or a finish-out we work to the drawings; on an existing building we survey what is there and tell you what it will actually take.

Medical and dental
Refrigerated medication, powered chairs, sterilisers and records systems that cannot simply stop.
Pharmacies
Refrigerated stock and dispensing systems, where a few hours of lost cooling is lost inventory.
Restaurants and food service
Walk-ins and reach-ins. A single lost freezer of product often exceeds a year of service plan.
Retail and multi-tenant
Lighting, POS and card terminals. Closed during an outage is revenue you never recover.
Warehouse and light industrial
Dock equipment, compressors, process loads and life-safety systems.
Offices and professional space
Servers, network gear and the ability to keep working through a regional outage.

We also handle commercial electrical tenant finish-out under the same license — see commercial electrical contracting. On a project that involves both, the generator, the transfer switch and the distribution work are not split across two trades who each assume the other owns the interface.

FAQ

Common questions

What is the 80% rule for generator sizing?
A standby generator should not run continuously above about 80% of its rated capacity. Sizing to 100% leaves nothing in reserve for startup surges, degrades the unit faster, and means any load you add later pushes it past its limit. When we size a system we work out your running load, add the largest single startup surge, then allow that 20% headroom on top. It is why a 22 kW unit is not the right answer for a 22 kW load.
Do I need to back up the whole house, or just some circuits?
Either works, and the difference is mostly cost. Backing up essential circuits — fridge, lights, outlets, internet, one HVAC zone — needs a much smaller unit. Whole-home coverage means not thinking about it during an outage. The sizing tool on this page will show you what each approach costs you in kW, which is usually the clearest way to see the trade-off.
Do I need HOA approval for a generator?
In most Fort Bend master-planned communities, yes. Exterior mechanical equipment normally goes through architectural review, and the committee will look at placement, screening, side-yard clearance and whether gas piping is visible from the street. It is worth starting that process early — approval timelines are set by the HOA, not by us. We can provide the equipment details and placement drawings the submission usually needs.
Do I need a permit to install a standby generator in Texas?
Yes. A standby generator installation involves both electrical and, in most cases, fuel-gas work, and that requires a permit and inspection from whichever authority has jurisdiction over your address. In Fort Bend County that may be the county or your city, depending on where you sit. We pull the permit and coordinate the inspection as part of the job, so it is not something you need to chase yourself.
