Job Task Planning and Organizing
  • Power systems and power station operators have to complete a set of routine tasks within their shifts to ensure adherence to operational standards. However, the order in which they perform their tasks is dependant upon what happens during shifts. They must be able to react quickly to situations as they arise and manage priorities. Equipment breakdowns, shortages of maintenance crews, delays in repairs, unplanned outages, storms, floods and other emergencies force them to frequently reorganize job tasks. Power systems and power station operators assist their supervisors in organizing, planning, scheduling and monitoring the activities of mechanical and electrical maintenance crews. (2)
Back to Top

Decision Making
  • Decide when probes and filters should be changed, and when lubricants should be added to operating equipment. Perform visual checks and consider factors such as the time of the year and the amount of water flowing through systems. (2)
  • Decide which tasks to assign to which field crews. Consider crews' skill levels, experience with particular equipment and ability to work quickly and safely. (2)
  • Decide when to bump up generation capacities due to anticipated increases in demand. Make these decisions based on previous usage rates. Poor decision making may incur unnecessary operating expenses. (3)
  • Decide to shut down power units because of equipment malfunctions and anomalies. Consider factors such as the nature of the failures and potential hazards to personnel and the environment. Failure to make the right decisions may result in emissions or leaks and heavy penalties for the organization. (4)

Problem Solving
  • Face equipment failures which constitute safety hazards. Advise supervisors and isolate equipment so it can be repaired or replaced by maintenance staff. (1)
  • Face shortages of maintenance crews when work needs to be done on generators, transformers, switching gear and other equipment. Review work orders and identify crews that can be removed from low-priority tasks to enable the needed maintenance to be completed first. (2)
  • You are notified that operators for upcoming shifts have called in sick. Contact on-call employees to check their availabilities. If you cannot find replacement workers, fill in the next shift yourself. (2)
  • Face unscheduled power outages which adversely affect clients. Locate faulty equipment and direct power restoration operations to get systems back on line as soon and as safely as possible. Should a generator cease to be operational, a power systems operator may reroute electricity and increase the capacity of other generators. (3)

  • Evaluate the sufficiency and quality of repair work done by mechanical and electrical maintenance crews. Review work orders to verify that specified tasks have been performed, test repaired equipment to determine if it is functioning correctly and visually inspect work areas to ensure there is no dirt and debris remaining. (3)
  • Evaluate the completeness and clarity of procedures that have been written for the inspection, operation and testing of power equipment. Ensure that crucial information has not been omitted and wording is not open to misinterpretation. (3)
  • Assess the appropriateness and efficiency of various rerouting options to accommodate scheduled power outages. Consider factors such as capacity levels of equipment along the routes and the likelihood of overloads and determine the best course of action to minimize inconvenience and loss for customers. (3)
