How quickly does a standby generator start?

Most commercial standby generators start and begin producing power within 10-15 seconds of detecting a utility outage. The automatic transfer switch handles the transition seamlessly. UPS batteries bridge the gap during the startup period.

Natural gas or diesel — which is better?

Natural gas generators connect to your utility gas line and never need refueling — ideal for facilities with reliable gas service. Diesel generators are more fuel-efficient and better for extended runtime, but require fuel storage and delivery. We recommend based on your location, runtime needs, and local regulations.

What size generator do I need?

Generator size depends on your critical load (in kW) and whether you are powering the entire building or just critical systems. We calculate the exact load from your electrical panel schedules and add 20-30% headroom for starting surges and growth.

Do generators need permits?

Yes. Commercial generators typically require electrical permits, building permits, and in some jurisdictions, air quality permits (SCAQMD in Southern California). We handle the entire permitting process.

What maintenance does a generator require?

Generators need oil and filter changes every 200-500 hours, coolant checks, battery testing, and annual load bank testing. We offer preventive maintenance contracts that cover all scheduled maintenance and emergency service.

Design and install commercial standby generator systems with automatic transfer switches for continuous power during outages.

Overview

A standby generator is the last line of defense against extended power outages. When the utility power fails and your UPS batteries are depleting, the generator starts automatically and provides continuous power until grid service is restored. Summit DNC designs and installs commercial generator systems sized for your critical load, with automatic transfer switches, fuel management, and maintenance programs.
