Ohio Power Landscape
The Grid We Engineer For in Ohio
Every power system study TPS delivers in Ohio accounts for the utilities, fault duties, and interconnection requirements specific to the state. This is the landscape our Ohio work sits in.
Ohio sits inside PJM Interconnection, the regional transmission operator, and its facilities are served by AEP Ohio, FirstEnergy, AES Ohio, and Duke Energy Ohio. The available fault current at any facility service is set by the serving utility transformer and feeder configuration. When a utility upgrades that equipment the fault current can shift, which is why short-circuit and arc flash studies should be revisited whenever utility-side work happens near your service.
Ohio has no OSHA-approved state plan, so employers in the state answer to federal OSHA. Federal OSHA enforces electrical safety through 29 CFR 1910 Subpart S, which 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 building or electrical inspection office enforcing the National Electrical Code as adopted in Ohio. 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 Ohio.

Ohio FAQ
Ohio Power System Study Questions
Who enforces arc flash compliance for Ohio facilities?
Ohio has no OSHA-approved state plan, so employers in the state 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.
Does my Ohio facility need an arc flash study?
If workers ever interact with energized equipment, such as troubleshooting, racking breakers, or 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.
How does Ohio's grid affect my power system study?
Ohio is part of PJM Interconnection and served by AEP Ohio, FirstEnergy, AES Ohio, and Duke Energy Ohio. The fault current available at your service comes from the utility, and it changes when the utility upgrades transformers or feeders, so short-circuit and arc flash results should be re-checked after any utility-side work.
Who can seal a power system study in Ohio?
A power system study used for compliance must be sealed by a Professional Engineer licensed in Ohio. True Power Systems holds an active Ohio PE license and stamps every Ohio deliverable.
What does an Ohio power system study include?
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.
