What we engineer
Emergency and standby power system design per NFPA 110 — generator sizing with block-load step analysis, automatic transfer switches (ATS) and paralleling switchgear, selective coordination per NEC 700.32/701.32, and fuel storage (day tanks, belly tanks, AST/UST) sized to NFPA 110 Class ratings with load shedding and priority sequencing. Healthcare essential electrical systems per NFPA 99 and NEC 517 — life safety, critical, and equipment branches with 10-second transfer per NEC Article 700.
Permits that actually pass
AHJs want PE-stamped one-lines, generator sizing calculations, fuel-storage plans meeting IFC Chapter 57 and EPA SPCC (40 CFR 112), air-quality permits for stationary engines, and seismic anchorage calcs per ASCE 7 Chapter 13 — we deliver the complete submittal package so your emergency power permit clears plan check the first time.
Backed by licensed PEs
All emergency power engineering is backed by Apex Grid Engineering: 10+ PEs licensed across 49 states, 20+ engineers, 15+ years of plan sets that pass plan check.
