Tennessee Power Landscape
Every power system study TPS delivers in Tennessee accounts for the utilities, fault duties, and interconnection requirements specific to the state. This is the landscape our Tennessee work sits in.
Tennessee wholesale power comes almost entirely from the Tennessee Valley Authority, the federal utility that operates the regional grid. TVA delivers through local power companies, including Memphis Light, Gas & Water, Nashville Electric Service, Knoxville Utilities Board, and EPB of Chattanooga, plus dozens of municipal and cooperative systems. The available fault current at a facility service is set by the local power company TVA-fed distribution, and it can shift when that equipment is upgraded, which is why short-circuit and arc flash studies should be revisited after utility-side work.
Tennessee operates its own OSHA-approved state plan, TOSHA, which covers both private-sector and public-sector employers. TOSHA adopts the federal electrical safety standards in 29 CFR 1910 Subpart S, which treat 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 TOSHA 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 Tennessee. 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 Tennessee.

Tennessee FAQ
Tennessee runs its own OSHA-approved state plan, TOSHA, which covers both private and public employers. TOSHA enforces the federal electrical safety rules in 29 CFR 1910 Subpart S, which reference 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.
Tennessee is served almost entirely by the Tennessee Valley Authority through local power companies like Memphis Light, Gas & Water, Nashville Electric Service, Knoxville Utilities Board, and EPB of Chattanooga. The fault current available at your service comes from that TVA-fed distribution and changes when equipment is upgraded, 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 Tennessee. True Power Systems holds an active Tennessee PE license and stamps every Tennessee 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.
