View Curriculum

This specialized, intensive diploma program will prepare you to install, maintain, test and service electrical power generation units up to 10,000 kilowatts that are used for emergency power, standby power and prime power generation, in compliance with regulated standards. The job market for qualified specialists in the electrical and alternate power generation field is strong and growing, due to supply shortages, climate disruptions and the increase in energy demands. Power generator systems ensure consistent power generation in response to unreliable electricity grids or when traditional hydroelectricity is unavailable.

Employment opportunities include working with generator companies that sell and service equipment for mining and aggregate production industries, the construction industry, manufacturing plants, hospitals, hotels, and large buildings that require a continuous source of portable, standby and emergency power. The operation and maintenance of these generators is a highly specialized field that requires specific training. Upon successful completion of this program, you will have acquired this expertise and will receive an Ontario College Diploma in Electrical Power Generation at the Technician level.

You will take the same program of study as the Heavy Equipment Techniques certificate during the first three semesters. Most of these courses are common to both areas of study. The second (summer) semester is a paid co-op. The fourth semester focuses exclusively on the skills required to work in the field of electrical power generation.

*Students complete their paid co-op experience over the summer semester. In this program, you pay tuition and fees for three semesters. In addition, students will pay a co-op fee (approximately $558.00) for administrative costs associated with the co-op.

As a result of the paid internship, I was offered a job prior to graduation. This is a unique program in a highly specialized field. The industry is growing quickly, and many companies are looking for skilled technicians. Fleming College provided a good balance in the curriculum between the necessary safety aspects and the knowledge of how to work with the generation systems.

Andrew Kilgour, program graduate.

The EPG program at Fleming college gave me the opportunity to have a career in a dynamic and very specialized field. Generators are everywhere, you just don’t see them. With the company I’m with now we provide services to almost any industry you can think of. The amount of work in this industry dwarfs the amount of skilled technicians available to do it. The Fleming EPG program provided me with a skill set that will ensure I’ll always have employment.

Denis Tyler, Graduate, Operations manager - Power generation

Our experience over the last 20 years with Fleming graduates of the EPG Program has been extremely positive. The students are well prepared to transition into a technician role or other support functions. Every student we have hired shows up ready to continue to learn and work. Our EPG graduates show their knowledge of safety and are advancing in training levels easily and quickly. Many of our long-standing EPG graduates still talk with pride about their experiences at Fleming. We will gladly continue to work with Co-op students and graduates going forward and support the EPG program.

  • The Centre for Heavy Equipment Technology at Frost Campus in Lindsay is the only one of its kind in Canada.
  • The Centre is known for its up-to-date training, extraordinary hands-on learning opportunities, high industry employment rates, and skilled, knowledgeable faculty.
  • The opportunity to acquire two specialized, in-demand skill sets, through a certificate in Heavy Equipment Techniques, and a diploma in Electrical Power Generation, will provide you with a unique, comprehensive and powerful combination of expertise when it comes to your job search.

The following skills and characteristics are key to your success in this field:

  • strong electrical interest
  • safety-minded and safety-aware
  • knowledge of and adherence to industry-approved standards and relevant codes
  • math skills
  • computing ability
  • strong customer service orientation
  • self-motivated
  • disciplined
  • good manual dexterity
  • willingness to work long/various hours

If you are a graduate of the Heavy Equipment Techniques program, you can apply and enter directly into the fourth semester of the Generator Service Technician program or re-enter the program at a later date. With one more semester of study, you can obtain an Ontario College Diploma, expand your skills, and your career opportunities. (The Generator Service Technician program shares the same courses as for the Heavy Equipment Technician certificate in the first three semesters.)

Servicing companies that maintain power supply, such as Total Power, GENREP Ltd., Gal Power Systems, Toromont Energy, Wajax, Cummins, and Paramount Power, employ electrical power generation technicians. Hospitals, airports and buildings over five storeys high all require a backup, uninterrupted power supply to meet fire code regulations. Mining and aggregate production industries, which are frequently operating in remote locations, also require technicians to install and maintain generators and electrical power supply. With rising energy demands, the instability of the power grid, and mining industry growth in Alberta and the north, it is easy to understand why the need for qualified technicians is on the increase in Ontario and across the country. Starting salaries range from $18.00 to $24.00 per hour, with plenty of overtime potential. Job titles include:

  • Generator Service Technician
  • service technician
  • maintenance technician
  • generator maintenance technician
  • emergency and standby generator technician
  • diesel mechanic.

All students entering this program are required to purchase and have available, tools and safety equipment for use in our labs. We ask that you acquire the equipment needed for the program prior to start-up.

To be admitted into any shop area, each student must wear CSA approved green-patch 8” OHM rated work boots - approx. $200.00. You will also be provided with a digital multi-meter, safety glasses, hard hat and coveralls which will be included in your program tuition. (You will be responsible for cleaning your coveralls.)

Personal Protective Equipment (PPE) must be worn in labs, the main shop, and on the yard. PPE is required in all areas at all times or you will be removed from the area.
