OUR STORY Rapid, dynamic, sustained growth Gemitech was founded in 1990 and, in just a few short years, grew to be recognized as medium and high voltage specialists. From the start, we were involved in most of the hydropower projects in the province. Later we expanded into wind power industrial and institutional sectors while continuing to pursue growth in hydropower. Today, we are recognized leaders in electrotechnical services in Quebec s energy, metallurgy, petrochemical, pulp and paper, manufacturing, and mining sectors and with leading public and private organizations. Our solid reputation has also opened the door to projects across Canada, in the United States, and abroad. OUR COMMITMENT Bringing together the best in the field Optimal electrical system management is crucial in any organization, in terms of both safety and cost efficiencies. When infrastructure involves complex electrical devices, mistakes have serious consequences, so choosing qualified experts with in-depth equipment knowledge is paramount. A wide range of expertise At Gemitech, our strength lies in the caliber of our multidisciplinary team of professionals. With this range of expertise, we re able to provide first-rate engineering as well as specialized testing and measurement services.
