Commercial Generators & Backup Power in Tempe, AZ

Back the entire operation, or just the systems you can't afford to lose — refrigeration, servers, security, and life-safety.

We handle the electrical scope end to end and coordinate fuel and placement. For server rooms and data centers, we integrate the generator with UPS so there's zero gap during the transfer.

A generator is only as good as the switch that connects it. The automatic transfer switch (ATS) constantly watches utility power, and the instant it drops, it disconnects your building from the grid and starts the generator — restoring power to your critical panels in seconds, with no one on-site pulling levers.

That grid disconnection is also a safety and code requirement, not a nicety. Backfeeding a generator onto the utility line can kill a lineman working to restore power, so proper transfer switching is non-negotiable. We install and program the ATS, coordinate it with your switchgear and distribution, and test the full sequence so you know it works before you need it.

Size matters in both directions. Too small and the generator can't carry the load; oversized and you've overpaid and the engine runs inefficiently. We run a real load calculation — factoring motor-starting inrush from HVAC and refrigeration — to right-size the unit for your operation.

Standby generators typically run on natural gas or diesel, and each has trade-offs in fuel storage, runtime, and maintenance. We'll help you weigh them, then set the generator up to self-test on a schedule and flag issues early. Keeping it ready is exactly what preventive maintenance is for — a backup system that fails when the grid does is worse than none at all.
