How to Hire a Substation Technician: License, Pay, Where to Recruit, and How to Screen

The job lives in the test set. O*NET's top-rated core task for powerhouse, substation and relay repairers (SOC 49-2095) — the occupation substation technicians work in — is inspecting and testing equipment and circuits to identify malfunctions or defects, using wiring diagrams and testing devices such as ohmmeters, voltmeters, or ammeters. Two more core tasks O*NET rates 81 and 80 for importance: analyzing test data to diagnose malfunctions or evaluate the effects of system modifications, and opening and closing switches to isolate defective relays, performing adjustments or repairs.

Around that core, the role touches your whole substation scope. O*NET has these technicians consulting manuals, schematics, wiring diagrams and engineering personnel to troubleshoot equipment problems, and scheduling and supervising the splicing or termination of cables in color-code order. BLS's Occupational Outlook Handbook profile for electrical and electronics installers and repairers — the group that covers this occupation — lists the service half of the job: discussing problems with customers, inspecting and testing equipment, diagnosing faults, repairing or replacing components, and keeping records of repairs and labor hours — that last one is your job-costing data.

Screen for the toolset, not just the trade. O*NET's technology-skills list for the occupation includes OMICRON Test Universe and Fluke FlukeView Forms (analytical software), Megger PowerDB (compliance software) and SCADA software. And post under a title from the occupation's own list: O*NET's sample job titles for the SOC include Substation Technician, Substation Electrician, Relay Technician, I&C Technician and E&I Technician. Substation technicians and relay technicians share the one SOC, and BLS OEWS does not split them.

Write the essential functions into the posting before you advertise. Under the ADA, a written job description prepared before advertising or interviewing is evidence of which job functions are essential — for this role, put the testing, switching and diagnosis work described above on the record before day one. The worker-side view of the job — what a substation technician does — lives on the career guide; this page stays on the hiring side.

Start by separating two different things: a state worker license and an industry certification. Worker licensing is a state-by-state question, and our research did not confirm a separate substation-technician license class. The nearest class it read is in Texas: the Texas Department of Licensing and Regulation licenses Journeyman Linemen for electrical work involving the maintenance and operation of equipment associated with the transmission and distribution of electricity from the electricity's original source to a substation for further distribution. That is a Texas license whose stated scope runs to the substation; our research did not confirm that it, or any other license, covers work inside one. Which credential, if any, your jurisdiction requires for this work is a question to put to your state licensing board before you write the posting.

The qualification OSHA's rules actually turn on is documented competence, not a card. Under 29 CFR 1910.269, only qualified employees may work on or with exposed energized lines, or in areas with unguarded, uninsulated energized parts at 50 volts or more. A qualified employee is one knowledgeable in the construction and operation of the electric power generation, transmission and distribution equipment involved, along with the associated hazards — and each qualified employee must be trained and competent in distinguishing exposed live parts, determining nominal voltage, knowing and maintaining minimum approach distances, using special precautionary techniques, PPE and insulated tools, and recognizing and controlling electrical hazards. Ask substation technician candidates to document that training; it is the credential your safety program is built on.

For the testing side of the role, the credential to know is NETA certification. NETA certifies electrical testing technicians at four levels under the ANSI/NETA ETT standard — Level 1 Trainee, Level 2 Certified Assistant, Level 3 Certified Technician, Level 4 Certified Senior Technician — and each higher level requires passing the exams for all previous levels. Two details matter when you verify a card. First, NETA Certified Technicians at Levels 2 through 4 must be employed by a NETA Accredited Company, with continuing-education and experience requirements behind the title; Level 1 is examined by the employer. Second, the experience ladder is steep: two years for Level 2, five for Level 3, and ten for Level 4, with two or more years of electrical technical education counting for at most one year. NETA certification is an industry credential tied to that accredited-company employment — not a state license — and our research did not confirm it as a requirement for utility substation jobs; check with NETA and your state licensing board before you write it into a posting as a requirement.

Switching is worth its own line in your requirements. NETA describes a Level 3 Certified Technician as capable of performing electrical power switching, and able to supervise Levels 1 and 2 — which makes Level 3, or documented equivalent training, the natural screen when the job includes operating switches on or near energized equipment. The exams behind the levels are closed-book and proctored: Levels 2 and 3 are 100-item multiple-choice exams and Level 4 is 65-item, each two hours, onsite; Level 2 requires a passing score of 410 or higher on a 200 to 500 scale. OSHA's crewing rule also names switching separately: installation, removal or repair of lines energized above 600 volts requires at least two employees present, with exceptions that include routine switching and emergency repairs to safeguard the public.

The national benchmark is BLS's Occupational Employment and Wage Statistics (OEWS) survey for May 2025. For Electrical and Electronics Repairers, Powerhouse, Substation, and Relay (SOC 49-2095), national, all industries, it reports a median of $49.53 per hour ($103,020 per year). The middle half of the distribution runs from $39.35 per hour at the 25th percentile to $57.15 at the 75th; the 10th percentile is $31.60 per hour ($65,730 per year) and the 90th is $62.46 ($129,920 per year). OEWS estimates employment in the occupation at 20,720.

Two cuts of the same survey matter for budgeting. By industry, the 12,920 repairers the survey places in electric utilities (NAICS 221100) earn a median of $105,940 per year ($50.94 per hour) — the largest single industry employer of the occupation, and the pay line a utility-side offer is benchmarked against. By state, the five highest-paying states by annual median are Oregon ($131,050), Hawaii ($127,330), Washington ($125,620), Colorado ($125,560) and Alaska ($125,260); the lowest is Nevada ($74,360). The state ranking is by median wage, not cost-of-living adjusted — benchmark the offer against your own service territory.

Three cautions keep the number honest. The SOC covers powerhouse and relay repairers too: substation technicians share it with relay technicians, and OEWS does not split them, so treat the figures as the occupation's, not one title's. It does not split union from non-union pay either — where a collective bargaining agreement covers your crews, the negotiated scale in that agreement is the figure that governs. And OEWS covers wage-and-salary employees, so the self-employed fall outside it.

If you develop apprentices instead of hiring documented testers, expect a stepped scale. Named programs set their own terms: the NW Line JATC's substation technician apprenticeship starts apprentices at 60% of the journeyman lineman wage and rises to 90%, and the California-Nevada JATC's runs 7,000 hours over nearly four years in seven steps. And if your crews travel, the FLSA rule on reimbursements still applies: travel payments, including per diem, are excluded from the regular rate used to compute overtime only when they reasonably approximate the expense — amounts at or below the federal travel or IRS rates are treated as reasonable.

Start from where the workers sit. BLS counts 12,920 of the occupation's 20,720 workers inside electric utilities (NAICS 221100). The pipelines into the occupation are long — two of the apprenticeships below require 7,000 on-the-job hours — so plan on running more than one recruiting channel at once.

The named pipelines are apprenticeship programs, and each sets its own entry rules — read the program's own standards before you recruit out of it. The American Line Builders JATC (ALBAT) runs a substation apprenticeship requiring 7,000 hours of on-the-job training, serving Illinois, Indiana, Kentucky, Maryland, Michigan, Ohio, Virginia, Washington D.C. and West Virginia. The California-Nevada JATC's substation technician apprenticeship is also 7,000 hours, over nearly four years in seven steps. The NW Line JATC's substation technician apprenticeship requires a Class A CDL with no restrictions, an aptitude test within the last two years and a high school diploma. If you need a credential already in hand rather than developing one, the NW Line JATC also offers a Substation Certification intended for current journey-level workers adding the certification to their skill set.

Post the role under a title the occupation actually uses. Your substation technician jobs listing is the seeker-facing side of this page, and the title list from the first section — Substation Technician, Substation Electrician, Relay Technician, I&C Technician, E&I Technician — is the occupation's own vocabulary; a posting labeled only with an internal job code gives candidates nothing to recognize. The hiring process guide walks the full sequence from posting to offer, and hiring electricians: the employer guide is the employer-side starting point.

Two rules shape the funnel itself. EEOC guidance warns that relying on word-of-mouth recruiting from a mostly homogeneous workforce may violate the law if it results in a homogeneous pool of new hires, and it is illegal to publish a job ad that shows a preference for, or discourages, applicants based on race, color, religion, sex, national origin, age (40+), disability or genetic information. Pay-transparency statutes reach these postings too: California and Washington employers with 15 or more employees must include the pay scale or wage scale in every posting (Washington adds a general description of benefits), and Colorado requires employers to disclose compensation, benefits and how to apply in all postings, internal and public.

What the pipeline produces: in O*NET's education survey for the occupation, 50% of respondents said a post-secondary certificate is required for new hires and 28% an associate degree — the shares O*NET's respondents reported for new hires in the occupation, alongside the apprenticeship routes above.

Screen in the order the rules attach: documented qualification first, certifications second, background checks third, and anything medical last.

Qualification evidence. Ask for the training record behind the word qualified. OSHA's standard requires the employer to verify compliance through supervision and at least annual inspections, and to make sure each employee has demonstrated proficiency before training is considered complete — so a technician moving from another employer should be able to name the equipment they were qualified on and show the training behind it. Then probe the core tasks directly: reading wiring diagrams and schematics, using ohmmeters, voltmeters and ammeters to isolate malfunctions, opening and closing switches to isolate a defective relay, and analyzing test data. Exposure to the software the occupation lists — OMICRON Test Universe, Megger PowerDB, SCADA — is a fair question for testing-shop work. If you run a hands-on assessment at your yard, FLSA rules treat work the employer suffers or permits as work time. No DOL rule our research read addresses a working trial by name — pay the hours for a hands-on working trial and confirm with the Wage and Hour Division.

NETA cards. Verify any NETA certification at its level — Level 2 Certified Assistant, Level 3 Certified Technician, Level 4 Certified Senior Technician — and at its experience floor: two years for Level 2, five for Level 3, ten for Level 4. And remember what the credential attaches to: NETA Certified Technician status is held through employment at a NETA Accredited Company, with continuing education and experience behind it, so confirm current standing with NETA when the certification matters to your scope of work.

Background checks. Before ordering a background report, the Fair Credit Reporting Act requires a clear written disclosure in a document consisting solely of that disclosure — it cannot sit inside the employment application — plus the applicant's written authorization. Before taking adverse action based on a report, give the person a copy of the report and a written description of their rights under the FCRA. One industry-specific layer: NERC's CIP-004-7 standard requires utilities to run personnel risk assessments — including a seven-year criminal history records check, renewed at least every seven years — for people with authorized unescorted physical or electronic access to high- or medium-impact BES Cyber Systems. That applies only to roles needing that access, not to every substation hire, but if your crews enter such facilities, plan the timeline for it.

Medical questions and cards. The ADA bars questions about disability and medical exams before a job offer, but you may ask whether and how a candidate can perform the job's functions — and pre-employment questions generally should be limited to what is needed to judge qualifications. Finally, screen credentials for what they are: an OSHA 10 or OSHA 30 card is not a license, and OSHA says the Outreach classes do not fulfil an employer's training duties under specific standards — the 30-hour class is more appropriate for supervisors or workers with some safety responsibility. The document that matters for this role is the documented qualification training above; confirm licensing requirements with your state licensing board.

Set the safety frame on day one and keep it on the calendar. OSHA's construction rules for electric power transmission and distribution lines and equipment live in 29 CFR part 1926 Subpart V, while maintenance work falls under 29 CFR 1910.269. The training rules have teeth an employer runs: training may be classroom or on-the-job, but the employer must verify it through supervision and at least annual inspections and must make sure each employee has demonstrated proficiency before training counts as complete — and OSHA considers a task performed less often than once a year to need retraining before the employee performs it. Before each job, the employee in charge holds a job briefing covering hazards, work procedures, special precautions, energy-source controls and PPE.

Two duties are specific to how substation crews work. Enclosed spaces: where the work involves a manhole, vault, tunnel or shaft with limited egress, employees entering or serving as attendants must be trained in entry hazards, procedures and rescue — substation vault work puts this in scope. And crewing: installation, removal or repair of lines energized above 600 volts requires at least two employees present, with exceptions that include routine switching and emergency repairs to safeguard the public — a staffing fact to build into crew scheduling, not discover at the job site. Emergency procedures, including pole-top and manhole rescue, are part of the required training for covered employees.

The administrative steps have fixed clocks. On Form I-9, the employee completes Section 1 at the time of hire and you complete Section 2 within three business days of hire; report the new hire to the state where they work within 20 days, sooner in some states. If you take travelers through a staffing agency, OSHA treats the staffing agency and the host employer as jointly responsible for the temporary worker's safety — including training, hazard communication and recordkeeping — and recommends putting each side's compliance responsibilities in the contract.

Retention in this role tracks the ladders your competitors offer. A technician you train is a multi-year investment — the ALBAT and California-Nevada substation apprenticeships run 7,000 hours, nearly four years' full-time work in the California-Nevada program — and utilities pay a median of $105,940 per year for these repairers, so a documented tester has options. Give them a ladder to climb: NETA's four levels, with supervision and power-switching capability opening up at Level 3, and programs like the NW Line JATC's Substation Certification built for journey-level workers adding a credential. Pay steps that track documented capability, and fund the continuing education the certifications require — the technician who can switch, test and document their way across your territory is the one worth keeping.

Employer information, not licensing, legal, code, or safety advice. License classes and certification requirements vary by state and by program — confirm with your state licensing board, and with OSHA, NERC, NETA, or employment counsel for your own situation.
