Industrial Generators and Backup Systems

Generator sizing is more nuanced than total facility load. Motor starting loads — particularly large compressors, pumps, and HVAC equipment — drive the generator size. We perform a step-load study that accounts for motor inrush current and develops a starting sequence so the generator can start the largest motor without voltage collapse.

Diesel offers better cold-weather starting and higher kW output per dollar, but requires on-site fuel storage and periodic fuel polishing. Natural gas eliminates fuel storage and refueling logistics but depends on the gas utility staying online during the event you are backing up against. We discuss the tradeoffs based on your specific facility and risk profile.

Load-bank testing applies a controlled resistive load to the generator at nameplate capacity to verify the engine and alternator perform under full load. New installations should be load-bank tested at commissioning, and standby generators should be tested annually. Generators that only see light test loads can develop wet stacking and reliability problems over time.

Yes. Paralleling switchgear allows two or more generators to share load and provides N+1 redundancy for facilities where a single generator failure cannot interrupt operations. We design and install paralleling switchgear with load-shed schemes that prioritize critical loads if total generation capacity is insufficient.

We coordinate with regional generator service organizations for routine maintenance — oil changes, fuel polishing, annual load-bank testing — and we handle electrical-side service, transfer switch maintenance, and any required protective device work. Most clients use a hybrid arrangement.

From signed contract to commissioned generator, most industrial generator projects run twelve to twenty-six weeks. Generator equipment lead times, particularly for larger units, drive the schedule. We submit equipment for fabrication immediately upon contract so lead time runs in parallel with site preparation. Call (307) 757-5553 to discuss your timeline.
