500–1,000 kW covers larger data centers, hospitals, industrial campuses, and mission-critical NFPA 110 Level 1 installations. Most units are diesel with EPA Tier 4 Final, large sub-base tanks for 24-72 hour runtime, and integrated paralleling. Permitting becomes a significant timeline driver in this class — AHJ review for sound, exhaust, fuel storage, and seismic restraint typically runs 60-120 days.
