Dispatchers record readings at a map of the transmission grid system. They keep track of the status of circuits and connections between users and the power lines. Dispatchers keep track of the weather and anticipate what needs it might produce. For example, a cold or heat wave usually brings higher power use. When more power is needed, they call control room operators to start the boilers and generators.
Dispatchers also handle emergencies, such as transformer failure.
They also operate and monitor equipment in substations. This equipment changes voltage up and down as well as the flow of electricity in and out of substations. Power Plant Operators is in the Manufacturing and Processing Career Cluster. Because power is needed 24 hours a day, operators must be at the plant all day. Thus operators and others work the day, evening, or night shift.
