North Carolina Power Landscape
Every power system study TPS delivers in North Carolina accounts for the utilities, fault duties, and interconnection requirements specific to the state. This is the landscape our North Carolina work sits in.
North Carolina is not part of a centralized RTO or ISO. The state operates within the Duke Energy Carolinas balancing authority inside the SERC reliability region, with Duke Energy Progress, Dominion Energy North Carolina in the northeast, the NCEMC cooperatives, and the ElectriCities municipal systems also serving facilities across the state. The available fault current at a facility service is set by the serving utility, and it shifts when transformers or feeders are upgraded, which is why short-circuit and arc flash studies should be revisited after utility-side work.
North Carolina operates its own OSHA-approved state plan, run by the NC Department of Labor, which covers both private-sector and public-sector employers. The state program 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 state inspector or an insurance auditor expects to see.
The authority having jurisdiction for the installation itself is typically the local building inspection office enforcing the North Carolina State Building Code, which incorporates the National Electrical 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 North Carolina.

North Carolina FAQ
North Carolina runs its own OSHA-approved state plan through the NC Department of Labor, covering both private and public employers. It 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.
North Carolina is not in a centralized RTO; its wholesale grid runs through the Duke Energy Carolinas balancing authority within SERC, with Duke Energy Progress, Dominion Energy NC, NCEMC, and ElectriCities municipal systems also serving facilities. 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 North Carolina. True Power Systems holds an active North Carolina PE license and stamps every North Carolina 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.
