Indiana Power Landscape
The Grid We Engineer For in Indiana
Every power system study TPS delivers in Indiana accounts for the utilities, fault duties, and interconnection requirements specific to the state. This is the landscape our Indiana work sits in.
Indiana sits inside MISO, the Midcontinent Independent System Operator, and the state is served by AES Indiana, Duke Energy Indiana, NIPSCO, Indiana Michigan Power, CenterPoint Energy Indiana, and the Hoosier Energy cooperative network. 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.
Indiana operates an OSHA-approved state plan: the Indiana Occupational Safety and Health Administration (IOSHA), administered by the Indiana Department of Labor, covers both private-sector and state/local government employers. IOSHA enforces electrical safety under 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 an IOSHA compliance officer 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 Indiana. 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 Indiana.

Indiana FAQ
Indiana Power System Study Questions
Who enforces arc flash compliance for Indiana facilities?
Indiana operates a state OSHA plan — IOSHA, administered by the Indiana Department of Labor — covering both private-sector and public-sector employers. IOSHA enforces electrical safety through 29 CFR 1910 Subpart S, which references NFPA 70E for arc flash risk assessment and equipment labeling.
Does my Indiana facility need an arc flash study?
If workers ever interact with energized equipment — troubleshooting, racking breakers, voltage testing — NFPA 70E calls for an arc flash risk assessment and IOSHA 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 Indiana's grid affect my power system study?
Indiana sits inside MISO, with facilities served by AES Indiana, Duke Energy Indiana, NIPSCO, Indiana Michigan Power, CenterPoint Energy Indiana, and Hoosier Energy. 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.
Who can seal a power system study in Indiana?
A power system study used for compliance must be sealed by a Professional Engineer licensed in Indiana. True Power Systems holds an active Indiana PE license and stamps every Indiana deliverable.
What does an Indiana 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.
