Wisconsin Power Landscape
Every power system study TPS delivers in Wisconsin accounts for the utilities, fault duties, and interconnection requirements specific to the state. This is the landscape our Wisconsin work sits in.
Wisconsin sits inside MISO, the regional transmission operator that coordinates the wholesale grid, with the state served primarily by We Energies in the southeast, Wisconsin Public Service in the northeast and Fox Valley, Madison Gas and Electric in the south-central area, Alliant Energy Wisconsin and Xcel Energy across other regions, and Dairyland Power Cooperative supplying the rural cooperatives. The available fault current at a facility service is set by the serving utility, and on paper-mill and food-processing loads it can shift when utilities upgrade transformers or feeders, which is why short-circuit and arc flash studies should be revisited after utility-side work.
Wisconsin 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 electrical inspection office enforcing the National Electrical Code as adopted in Wisconsin through the state commercial building code. 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 Wisconsin.

Wisconsin FAQ
Wisconsin has no state OSHA plan, so all 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.
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.
Wisconsin is in MISO and served primarily by We Energies, Wisconsin Public Service, Madison Gas and Electric, Alliant Energy, Xcel Energy, and Dairyland Power Cooperative. The fault current available at your service comes from the serving utility and changes when it 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 Wisconsin. True Power Systems holds an active Wisconsin PE license and stamps every Wisconsin 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.
