Substation Technician Certification
Comprehensive training and resources for professional certification at all levels.
Substation technician training and NETA or NICET certification
Substation technicians test, commission, and maintain the equipment that keeps the grid running. Here is what the job involves, how NETA and NICET certification Levels I through IV work, and where to start.
What does a substation technician do?
A substation technician is the person on the test cart. They run insulation resistance, contact resistance, breaker timing, transformer ratio, power factor, partial discharge, and protective relay tests on the equipment that moves megawatts. They commission new substations before energization and maintain old ones for the next thirty years. Demand is steady — the grid does not stop aging, and most working technicians are within ten years of retirement.
Pay reflects skill scarcity. NETA or NICET Level II technicians average $35–$50/hr depending on region. Level III and IV technicians (and those who can stamp test reports under PE oversight) earn substantially more. The job involves travel, off-shift outage work, and a healthy respect for things that can kill you if you do them wrong — which is exactly why proper training matters.
Two organizations certify electrical testing technicians: NETA (the InterNational Electrical Testing Association), under the ANSI/NETA ETT standard, and NICET (the National Institute for Certification in Engineering Technologies), through its Electrical Power Testing program. Both use four levels: Level I (trainee, supervised testing), Level II (independent execution of routine tests), Level III (complex testing and supervising crews), and Level IV (the senior technical authority on a job site). Many specifications accept either; check which one your employer or project requires. For a side-by-side of the requirements, see our NETA and NICET certification guide.
