In-person · Knoxville, TNElectrical safety training in Knoxville, TN
Knoxville sits next to Oak Ridge, where a uranium plant is being rebuilt, the first new non-light-water reactors are under construction and TVA holds a permit for a small modular reactor. We train the electrical crews who build, commission and maintain that work, at your facility or in an in-person class we set up in Knoxville when you ask.
Tennessee runs its own OSHA-approved state plan. Private employers here are inspected by Tennessee Occupational Safety and Health Administration (TOSHA), Tennessee Department of Labor and Workforce Development, not federal OSHA. Every class is live, on the 2027 edition of NFPA 70E, and taught by a Certified Safety Professional. Tennessee electrical safety training requirements →
Among the teams we have trained in the last year
Four ways to train your Knoxville crew
Crews we train in and around Knoxville: federal site contractors, advanced nuclear construction, automotive suppliers, public power, universities and hospitals, electrical contractors.
What the class covers for Knoxville crews
New reactor and process buildings get energized system by system while construction continues around them. We teach the handoff from construction rules to operating rules at each energization step.
DOE contractor sites work under 10 CFR 851, which lists NFPA 70E among its required standards. We help crews who move between DOE work and private plants keep one consistent set of safe work practices.
Manhattan Project era buildings and decades-old plant distribution still carry load while replacements rise. We cover condition of maintenance and why an old label may not match the gear behind it.
Supplier plants like the DENSO campus in Maryville run dense 480 V distribution and robotic cells. We spend time on when energized diagnostic work is justified and how to set it up.

Tennessee: what applies to your crews
Enforcement: TOSHA, with federal exceptions
TOSHA, part of the Department of Labor and Workforce Development, runs Tennessee's state plan for private employers and state and local government. Federal workplaces are outside it, and DOE contractor sites in Oak Ridge work under DOE's own worker safety rule, 10 CFR 851.
Licensing: state contractor, local journeyman
The Board for Licensing Contractors licenses electrical contractors for projects of $25,000 and up and issues the Limited Licensed Electrician credential for smaller work. Tennessee has no statewide journeyman card, so individual electrician licensing is local.
Where NFPA 70E fits
OSHA and TOSHA do not enforce NFPA 70E. Private employers use it to show how they meet 1910 Subpart S and 1926 Subpart K, the General Duty Clause covers recognized hazards, and DOE's rule names NFPA 70E directly for its contractors.
Knoxville's electrical work environment
Oak Ridge sets the tone for the region. At the Y-12 National Security Complex, the Uranium Processing Facility moved into bulk electrical installation with more than 100 miles of conduit and cable in place, and NNSA has slated construction completion for 2027. A 245,000-square-foot Lithium Processing Facility is next, replacing functions in the Manhattan Project era Beta-2 building.
Private nuclear work is growing around the federal sites. Kairos Power is building Hermes 1, a 35 MWt salt-cooled test reactor, on the former K-33 gaseous diffusion site, and broke ground on the 50 MWe Hermes 2 in April 2026. A few miles away, the NRC approved TVA's construction permit for a BWRX-300 at the Clinch River site in 2026, though TVA's board still has to approve the final financial commitment.
Knoxville itself runs on manufacturing, healthcare and the University of Tennessee. DENSO's Maryville plant, the company's largest U.S. factory, employs more than 4,000 people in neighboring Blount County. More than 150 nuclear companies operate in the Oak Ridge and Knoxville area, according to NNSA, so a single contractor's crew can move between a federal site, a reactor build and an auto supplier in the same year.
Nuclear and federal projects around Oak Ridge
These are the Oak Ridge area projects pulling the most electrical labor into the Knoxville region. Several are first-of-a-kind builds with long commissioning phases.
| Site | What is there | Status |
|---|---|---|
| Uranium Processing Facility NNSA (Y-12) | Replacement uranium plant at Y-12, with construction slated to finish in 2027 and full operations by 2031. | Under construction |
| Lithium Processing Facility NNSA (Y-12) | 245,000-square-foot facility replacing the Beta-2 building, with construction expected to start in FY2026. | Planned |
| Hermes 1 Kairos Power | 35 MWt salt-cooled test reactor on the former K-33 site, expected to be ready in 2028. | Under construction |
| Hermes 2 Kairos Power | 50 MWe power-producing reactor, groundbreaking April 2026 and expected in 2030. | Under construction |
| Clinch River Unit 1 TVA | BWRX-300 small modular reactor with an NRC construction permit issued in 2026 and no construction start date set. | Planned |
| DENSO Manufacturing Tennessee DENSO | Maryville plant with more than 4,000 employees, DENSO's largest U.S. manufacturing site. | Operating |
KUB and the TVA distributors
The Knoxville Utilities Board distributes TVA power to more than 226,000 electric customers in Knox County and parts of seven surrounding counties, through 64 substations. Oak Ridge has its own municipal electric department, and the Clinton Utilities Board, Loudon Utilities Board and other TVA distributors serve the towns around it, so contractors deal with several distributors' clearance practices across the region.
TVA generates and transmits the power, and its Clinch River site could host up to four 300 MW reactors. Kairos has a power purchase agreement with Google and TVA aimed at 500 MW by 2035. Federal and TVA work sites can fall under different safety jurisdiction than a private plant down the road, so confirm who has jurisdiction before the job starts.

Questions from Knoxville employers
We work at Y-12 or ORNL. Does your class fit DOE requirements?
Can you train a startup crew before a reactor or process building is energized?
Does TOSHA cover a city utility like KUB or Oak Ridge Electric?
Our electrician holds a Tennessee LLE. Is that enough?
Does finishing the class make someone a qualified electrical worker?
What the people in the room say
“Virtual can never replace hands-on, but the engagement from our instructor and the class made it feel more engaging than some in-person courses I've taken.”
“Probably one of the most useful safety courses I've ever attended. Rick genuinely cares about people and their well-being.”
“This is the 2nd arc flash training course I've taken and the class was amazing. I feel like I'm leaving the training safer than before I took this class.”
