Missouri Power Landscape
Every power system study TPS delivers in Missouri accounts for the utilities, fault duties, and interconnection requirements specific to the state. This is the landscape our Missouri work sits in.
Missouri straddles two wholesale grids: the eastern and central parts of the state, served by Ameren Missouri, sit inside MISO, while the western Missouri territory served by Evergy sits inside the Southwest Power Pool (SPP). Liberty (Empire District) in the southwest and the Associated Electric Cooperative network round out the picture, alongside municipal systems like City Utilities of Springfield. The available fault current at any facility service is set by the serving utility and can shift when that utility upgrades transformers, ties, or substations, which is why short-circuit and arc flash studies should be revisited after any utility-side work.
Missouri does NOT operate a state OSHA plan. Every employer in the state, public and private, answers to federal OSHA, which enforces electrical safety through 29 CFR 1910 Subpart S and treats NFPA 70E as the consensus standard for arc flash risk assessment and equipment labeling. A current, PE-sealed arc flash study is the documentation a federal OSHA inspector or an insurance auditor expects to see.
The authority having jurisdiction for the installation itself is typically the local or county electrical inspection office enforcing the National Electrical Code as adopted in Missouri. Every study True Power Systems delivers in the state is modeled to current IEEE and NFPA methodology and sealed by a Professional Engineer licensed in Missouri.

Missouri FAQ
Missouri has no state OSHA plan, so all employers in the state, public and private, answer to federal OSHA. Federal OSHA enforces electrical safety through 29 CFR 1910 Subpart S, which references NFPA 70E for arc flash risk assessment and equipment labeling.
If workers ever interact with energized equipment — troubleshooting, racking breakers, voltage testing — NFPA 70E calls for an arc flash risk assessment and OSHA expects equipment to carry incident-energy labels. New equipment, a service upgrade, or a change in utility fault current all trigger a new or updated study.
Missouri straddles two grids — Ameren Missouri territory sits in MISO, while Evergy territory in western Missouri sits in SPP. Liberty (Empire) and Associated Electric Cooperative serve other areas. The fault current available at your service comes from the utility and changes when the utility upgrades equipment, so short-circuit and arc flash results should be re-checked after utility-side work.
A power system study used for compliance must be sealed by a Professional Engineer licensed in Missouri. True Power Systems holds an active Missouri PE license and stamps every Missouri deliverable.
A complete package covers incident-energy calculations and arc flash boundaries, ANSI Z535 equipment labels, short-circuit and equipment-duty evaluation, protective-device coordination, an as-studied one-line diagram, and a PE-sealed report.
