Emergency Power Engineering in Alton, IL

Alton is a Mississippi River city in the Metro East, with riverfront redevelopment, Southern Illinois University's dental school, and industrial activity along the river corridor shaping its construction market.

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.
