A substation technician installs, connects and services the equipment inside an electrical substation — transformers, circuit breakers, bus work, switchgear and the grounding grid beneath them.
It is the station side of the line trade: ALBAT, an outside-line JATC, trains its substation apprentices for that installation, connection and service work, and federal wage data counts 20,720 workers in the closest occupation group, at a median of $103,020 a year.
What is a substation technician?
A substation technician works on the equipment where the power system concentrates: the transformers that change voltage between levels, the circuit breakers that interrupt current, the bus work and switchgear that route it, and the grounding grid beneath the yard.
ALBAT — the American Line Builders JATC, which runs line, substation and cable splicer apprenticeships across IBEW's 4th and 6th districts — describes the core of its substation program as "installation, connection and service of substation transformers and circuit breakers for maintenance and new construction."
In federal statistics the role doesn't get its own line.
The closest occupation is SOC 49-2095, "electrical and electronics repairers, powerhouse, substation and relay," a grouping that also covers powerhouse repairers.
In the May 2025 Occupational Employment and Wage Statistics release it counted 20,720 workers nationally.
Where the role sits in the craft: the substation apprenticeships cited on this page — ALBAT's, the California-Nevada JATC's and NW Line JATC's — run through outside-line JATCs, the same joint system that trains linemen, and the California-Nevada JATC sets the same entry minimums for its substation and lineman programs.
That places the role on the line side of the trade rather than the inside-electrician side.
Substation work is one of the line-work careers this site covers — the line-work careers guide covers the wider trade.
What does a substation technician do?
Apprenticeship curricula state the work precisely, because completing the apprenticeship is what earns the journey-level title — the California-Nevada JATC ties "journeyman Substation Technician" status to the full 7,000 hours.
The ALBAT substation program, for example, teaches its apprentices:
- grounding-grid construction
- foundations and steel structure erection
- cable pulling and termination
- installing substation transformers and circuit breakers
- bus work and switchgear assembly
- minimum approach distance near energized circuits
ALBAT frames the program as covering "maintenance and new construction," and the list reads that way as a job description.
The construction half builds capacity: grounding grids, foundations, steel structures, pulled and terminated cable, and transformers, breakers and bus set into new or expanded stations.
The service half keeps what is already there working — the same equipment, connected and serviced through its life.
The curriculum's last line shapes the day-to-day more than any other.
A substation is a live environment: OSHA's rules for electric power generation, transmission and distribution work (29 CFR 1910.269) allow only qualified employees to work on or with exposed energized lines, or in areas with unguarded, uninsulated energized parts at 50 volts or more.
A qualified employee, as the rule defines the term, is trained to distinguish exposed live parts, determine the nominal voltage of exposed live parts, know and maintain minimum approach distances, use special precautionary techniques, protective equipment and insulated tools, and recognize and control electrical hazards.
That is why minimum approach distance appears on ALBAT's list — it is one of the competencies the rule requires of a qualified employee.
One nearby specialty: the relay technician.
O*NET lists Relay Technician among the sample job titles for SOC 49-2095, alongside Substation Technician — but our research found no primary-source utility job-family definitions drawing the line between the two roles, so treat that boundary as employer-specific.
Substation technician vs substation electrician: same job?
Close enough that O*NET lists both titles for the same federal occupation: the sample job titles it publishes for SOC 49-2095 include Substation Technician and Substation Electrician side by side.
The apprenticeship system titles the role "substation technician" — the California-Nevada JATC's program ends in "journeyman Substation Technician" status, and NW Line JATC runs a Substation Technician Apprenticeship.
On this site the two titles share one role page and one salary page.
The caveat: a posting is only as good as its duty list, so when you compare openings, judge the list rather than the word.
The federal data blurs the titles rather than choosing one.
Our research found no substation-technician-only SOC: the closest group, SOC 49-2095, also includes powerhouse repairers, and the sample titles O*NET publishes for it run Substation Technician, Substation Electrician and Relay Technician alongside I&C and E&I technicians.
And in the same May 2025 OEWS release, 7,950 workers classified as electricians (SOC 47-2111) worked in electric power generation, transmission and distribution, at an annual median of $106,640 — evidence that power-industry employers also hire under the electrician title.
The duties decide what a posting really is.
Licensing is a separate question, and it varies by state.
Texas, for one, exempts from its electrician licensing act work on "equipment under the exclusive control of an electric utility, electric cooperative, or power generation company" (Texas Occupations Code 1305.003(a)(5)) — so where a station job falls in Texas turns on who controls the equipment, not on the word in the title.
Our research checked Texas's rule only; treat any title-to-license assumption as a question for your state's licensing board, not the job posting.
Who hires substation technicians?
Utilities.
The industry's utility employers span investor-owned utilities, municipal utilities and cooperatives, and BLS describes line workers employed by local utilities maintaining equipment such as transformers, voltage regulators and switches.
On screening: for staff with authorized unescorted physical or electronic access to high- or medium-impact BES Cyber Systems, NERC's CIP standards require utilities to run personnel risk assessments, including a seven-year criminal history records check renewed at least every seven years — the requirement turns on that access, not the job title, so it reaches some substation and control staff rather than every line worker.
Contractors.
ALBAT — the American Line Builders JATC — trains its substation apprentices in the construction tasks listed above, for "maintenance and new construction."
Our research did not confirm which contractors hire substation technicians or how station work divides between utility crews and contractors; ask the apprenticeship program which employers its apprentices work for.
Testing firms.
Electrical testing is a related setting rather than a confirmed employer of this role: NETA certifies electrical testing technicians at four levels under the ANSI/NETA ETT standard, and NETA Certified Technicians are, by definition, employed by a NETA Accredited Company.
That ties the credential to the accredited testing firm rather than to a utility; our research did not confirm that those firms hire under the substation technician title.
On demand: our research found no BLS projection for SOC 49-2095 specifically.
The nearest federal projection covers the wider line trade: BLS projects employment of electrical power-line installers and repairers (SOC 49-9051) to grow 10 percent from 2025 to 2035, from 131,900 to 145,500 jobs — much faster than the average — naming rising electricity demand, new development, grid upgrades and AI data centers as drivers.
Treat the 10 percent as the line-trade number, not a substation-specific one.
How do you become a substation technician?
The route in, at the programs whose requirements are public, is a substation apprenticeship inside the outside-line craft.
Programs write their own entry rules and hour counts, and they differ — BLS's outlook for the line trades describes line apprenticeships and other employer-sponsored training as lasting up to 3 years, sometimes administered jointly by employer and union, while the substation programs whose hour counts are public — ALBAT's and the California-Nevada JATC's — publish 7,000-hour requirements.
The published requirements:
ALBAT — the American Line Builders JATC covering IBEW's 4th and 6th districts — requires 7,000 on-the-job hours for its substation apprenticeship, the same as its line and cable splicer programs (transmission and URD apprenticeships run 4,000).
Its substation curriculum is the duty list from the section above, grounding grids through switchgear.
The California-Nevada JATC runs a seven-step substation technician apprenticeship of 7,000 hours over nearly four years, with the same entry minimums as its lineman program: age 18, a high school diploma or GED, and an unrestricted commercial driver license.
NW Line JATC requires a Class A CDL with no restrictions, a high school diploma, and an aptitude test taken within the previous two years.
Its apprentice pay starts at 60 percent of the journeyman lineman wage and rises to 90 percent across the progression.
Two practical notes on the commercial-license thread.
A CDL driver must pass a pre-employment controlled-substances test before first performing safety-sensitive functions for an employer, under DOT rules (49 CFR 382.301), with limited exceptions.
And of the programs above, the two that state a license requirement — California-Nevada and NW Line — require it unrestricted; the ALBAT requirements on this page cover hours, not licenses, so confirm its license rule with the program.
Already a journey-level worker?
There is a second door: NW Line JATC offers a Substation Certification for current journey-level workers, separate from its entry-level apprenticeship — a crossover route into station work.
On the testing side, the credential path runs through NETA's four ETT levels — Level 1 Trainee through Level 4 Certified Senior Technician, each level requiring the ones before it — but NETA certification is tied to employment at a NETA Accredited Company.
It is not a utility credential and not a license; its home is the accredited testing firm, not the utility apprenticeship.

How much do substation technicians make?
BLS's OEWS release for May 2025 puts the median wage for SOC 49-2095 — electrical and electronics repairers, powerhouse, substation and relay — at $103,020 a year, or $49.53 an hour.
The 10th percentile earned $65,730 and the 90th $129,920, and the group counted 20,720 jobs nationally.
Read those figures with their scope attached: the SOC also includes powerhouse repairers, so it is wider than substation work alone, and a federal median is an occupation-wide figure rather than a journeyman rate.
One program publishes its apprentice scale: NW Line's substation apprentices start at 60 percent of the journeyman lineman wage and rise to 90 percent across the progression.
