EXPOSED
Modal worker here runs a fossil, hydro, or combined-cycle plant from a control room: monitoring SCADA displays, adjusting load and steam parameters, logging readings, and coordinating with dispatch — all of which DCS automation and predictive analytics have been eating for two decades, long before LLMs. What holds is the physical half: field rounds, manual valve and breaker switching, lockout/tagout, startup and shutdown sequences, and diagnosing why a pump is cavitating when instrumentation disagrees with reality. The bigger threat to this occupation isn't AI at all — it's plant retirements and the shift to unstaffed or remotely-operated generation, which is already shrinking headcount per megawatt.
Mixed — a routine tier and a judgment tier. Load-following, setpoint adjustment, and log-keeping are already handled by the DCS with the operator supervising, but the trip-and-recovery work — cold starts, condenser vacuum problems, chasing a bad transmitter against physical evidence — still needs someone in the room, which puts it mid-band rather than in single digits.
Hands-on in uncontrolled environments. Field rounds through turbine halls and boiler decks at 100°F+, hanging LOTO tags, racking breakers, stroking valves by hand when air is lost, and reading local gauges that aren't wired to anything are unavoidable and happen in a plant that is noisy, hot, and pressurized — well past a hybrid control-room job.
Certification preferred, not legally required. Most fossil and hydro operators hold NERC system-operator certification or a state boiler/turbine operator license and are named on the shift log, but the plant manager and the utility carry the regulatory exposure, so the credential constrains who can hold the seat without making the individual the personal defendant.
Anonymous artifact production. Dispatch cares about MW delivered and ramp rate, not which operator is on shift; the only relationship that matters is the handoff to the next crew, which is documented in the turnover log precisely so it doesn't depend on the person.
Meaningful discretion. Deciding to trip a unit versus riding through an abnormal vibration or low drum level is a call worth millions in equipment and it lands on the operator in seconds, but most of those decisions are bounded by written alarm-response procedures and operating limits that specify the action.
