Pennsylvania Power Landscape
Every power system study TPS delivers in Pennsylvania accounts for the utilities, fault duties, and interconnection requirements specific to the state. This is the landscape our Pennsylvania work sits in.
Pennsylvania sits inside PJM Interconnection, the regional transmission operator, and its facilities are served by PPL Electric Utilities in the central east, PECO in the southeast, Duquesne Light around Pittsburgh, FirstEnergy through its four PA distribution companies (Met-Ed, Penelec, Penn Power, West Penn Power), and UGI Utilities. The available fault current at a facility service is set by the serving utility, and on heavy-industrial loads and new Marcellus shale gas infrastructure it changes when transformers or feeders are upgraded, which is why short-circuit and arc flash studies should be revisited after utility-side work.
Pennsylvania has no OSHA-approved state plan, so employers in the Commonwealth 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 Pennsylvania Uniform Construction Code, which adopts the National Electrical Code. Every study True Power Systems delivers in the Commonwealth is modeled to current IEEE and NFPA methodology and sealed by a Professional Engineer licensed in Pennsylvania.

Pennsylvania FAQ
Pennsylvania has no state OSHA plan, so all employers in the Commonwealth 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.
Pennsylvania is in PJM Interconnection and served by PPL, PECO, Duquesne Light, the four FirstEnergy PA utilities, and UGI. The fault current available at your service comes from the serving utility and changes when it upgrades equipment, especially on heavy-industrial loads and new Marcellus shale infrastructure, 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 Pennsylvania. True Power Systems holds an active Pennsylvania PE license and stamps every Pennsylvania 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.
