Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Power Plant Operators

Operating and troubleshooting utility-grade shore-based power generation systems transfers directly to generator operation and monitoring for equipment problems.

How to prepare: Seek supervised operator training on the target plant's generating equipment and controls, focusing on output adjustment and startup and shutdown procedures.

What the civilian work involves

Control generator output to match the phase, frequency, or voltage of electricity supplied to panels.
Monitor power plant equipment and indicators to detect evidence of operating problems.
Start or stop generators, auxiliary pumping equipment, turbines, or other power plant equipment as necessary.

Civilian tools and software (examples)

Computerized maintenance management system CMMS

Electrical and Electronics Repairers, Commercial and Industrial Equipment
