Hydropower technician

A hydropower technician


Hydropower technicians install and maintain systems in hydropower plants. They perform inspections, analyse problems and carry out repairs. They ensure the turbines operate in compliance with regulations, and assist the hydropower engineers in the construction of turbines.

Hydropower technicians typically o the following:

  • Monitor and control activities associated with hydropower generation.
  • Operate plant equipment, such as turbines, pumps, valves, gates, fans, electric control boards, and battery banks.
  • Monitor equipment operation and performance and make necessary adjustments to ensure optimal performance.
  • Perform equipment maintenance and repair as necessary.
  • Operate high voltage switches or related devices in hydropower stations.
  • Identify or address malfunctions of hydroelectric plant operational equipment, such as generators, transformers, or turbines.
  • Inspect water-powered electric generators or auxiliary equipment in hydroelectric plants to verify proper operation or to determine maintenance or repair needs.
  • Implement load or switching orders in hydroelectric plants, in accordance with specifications or instructions.
  • Start, adjust, or stop generating units, operating valves, gates, or auxiliary equipment in hydroelectric power generating plants.
  • Perform preventive or corrective containment or cleanup measures in hydroelectric plants to prevent environmental contamination.
  • Maintain or repair hydroelectric plant electrical, mechanical, or electronic equipment, such as motors, transformers, voltage regulators, generators, relays, battery systems, air compressors, sump pumps, gates, or valves.

Working conditions

Hydropower technicians work around heavy equipment and must wear protective gear and clothing and follow safety procedures to prevent injuries. Technicians spend their work day on their feet, sometimes standing or kneeling to make repairs in confined spaces. They may also climb stairs and ladders. The job can be physically demanding so physical stamina and fitness is required. Technicians work full-time hours, usually 40 hours per week. They often work in 8- or 12-hour shifts, and occasionally work overtime to make emergency repairs as needed.

Minimum qualifications

Most hydropower technicians have an associate’s degree in engineering technology, renewable energy environmental science, or a related field. Some employers prefer to hire technicians who hold a bachelor’s degree. Technicians usually participate in an apprenticeship or some form of work-study program at a hydroelectric facility or related industry while they are in school. 

ISCO skill level

ISCO skill level is defined as a function of the complexity and range of tasks and duties to be performed in an occupation. It is measured on a scale from 1 to 4, with 1 the lowest level and 4 the highest, by considering:

  • the nature of the work performed in an occupation in relation to the characteristic tasks and duties
  • the level of formal education required for competent performance of the tasks and duties involved and
  • the amount of informal on-the-job training and/or previous experience in a related occupation required for competent performance of these tasks and duties.

Hydropower technician is a Skill level 3 occupation.
