View unit group

This group performs some or all of the following duties:

Power engineers

• Operate automated or computerized control systems, stationary engines and auxiliary equipment such as reactors, boilers, turbines, generators, pumps, compressors, pollution control devices and other equipment to generate electrical power and to provide light, heat, ventilation and refrigeration for buildings, industrial plants and other work sites
• Start up and shut down power plant equipment, control switching operations, regulate water levels and communicate with systems operators to regulate and coordinate transmission loads, frequency and line voltages
• Monitor and inspect plant equipment, computer terminals, switches, valves, gauges, alarms, meters and other instruments to measure temperature, pressure and fuel flow to detect leaks or other equipment malfunctions and to ensure plant equipment is operating at maximum efficiency
• Analyze and record instrument readings and equipment malfunctions
• Troubleshoot and perform corrective action and minor repairs to prevent equipment or system failure
• Respond to emergency situations if required
• Clean and lubricate generators, turbines, pumps and compressors and perform other routine equipment maintenance duties using appropriate lubricants and hand, power and precision tools
• Maintain a daily log of operation, maintenance and safety activities, and write reports on plant operation and non-compliance
• May assist in the development of operation, maintenance and safety procedures.

Power systems operators

• Operate and monitor computerized switchboards and auxiliary equipment in electrical control centres to control the distribution and to regulate the flow of electrical power in the transmission network
• Coordinate, schedule and direct generating station and substation power loads and line voltages to meet distribution demands during daily operations, system outages, repairs and importing or exporting of power
• Monitor and visually inspect station instruments, meters and alarms to ensure transmission voltages and line loadings are within prescribed limits and to detect equipment failure, line disturbances and outages
• Issue work and test permits to electrical and mechanical maintenance personnel, assist maintenance and technical personnel to locate and isolate system problems, and assist during routine system testing
• Complete and maintain station records, logs and reports.

• Trade certification is available, but voluntary for power engineers in Nova Scotia.
• Completion of secondary school is usually required.
• Control room operators at nuclear power plants require licensing from the Canadian Nuclear Safety Commission.
• Power systems operators require completion of a three- to five-year power system operator apprenticeship program or over three years of work experience in the trade and some college or industry courses in electrical and electronic technology.
• Power engineers require a provincial or territorial power engineering certificate according to class. There are five classes in Manitoba, Saskatchewan, Alberta and British Columbia while there are four classes in Newfoundland/Labrador, Nova Scotia, Prince Edward Island, New Brunswick, Quebec, Ontario, Yukon, Northwest Territories and Nunavut territories.
• Trade certification is available, but voluntary for power systems operators in Newfoundland and Labrador.
• Power engineers require a college training program in power engineering and several years of work experience. An exam is mandatory to move from one class to the other.

• Progression from lower to higher classes for power or stationary engineers is dependent on further training and experience.
• Progression to supervisory positions is possible with experience.
• There is little mobility between nuclear power generation station operators and other classic or alternative power generation station operators.

• Civil and mechanical engineers (2130)
• Electrical, electronics and computer engineers (2131)
• Manufacturing and processing engineers (2132)
• Nuclear power station equipment mechanic (in 72400 Construction millwrights and industrial mechanics)
• Other engineers (2139)
• Supervisors, petroleum, gas and chemical processing and utilities (92011)
