The Power Engineering Techology Diploma allows you to maintain and operate heating and power plants, refrigeration systems and auxiliary equipment like pumps, compressors, steam turbines, electrical generators, cooling towers and water treatment systems. Become a certified 3rd class power engineer with a two-year diploma. Your first year covers everything you need to know to take the 4th class power engineer exams. It is the same material covered in our one-year certificate program, and if you already have 4th class certification from a provincial safety authority, you will receive a credit for the first year and enter the second year of the program. Your second year builds on everything you learned in first year and will prepare you for the 3rd class power engineer exams.
