When demand on the grid spikes, most people notice only if something goes wrong. Behind the scenes, line crews and control-room operators are working extended shifts to make sure it doesn’t.
Control-room staff monitor load in real time, shifting power between substations to prevent any single point of the network from being overwhelmed. It’s a job of small, constant adjustments rather than dramatic interventions — the kind of work that’s invisible when it succeeds.
Field crews face a different challenge: equipment failures are more likely during extreme heat, and repairs often happen outdoors in the same conditions driving the demand spike in the first place. Utilities have expanded heat-safety protocols in recent years, including mandatory cooling breaks and adjusted shift lengths during the worst stretches.

Industry groups say staffing these roles remains a challenge, with retirements outpacing new apprenticeships in several regions — a gap utilities are racing to close before the next heat wave arrives.
