We have built Quebec’s largest energy networks since 1970. We successfully execute complex, ambitious, and above all, sustainable projects involving power transmission lines, electrical transformer stations, or civil engineering works.
In partnership with our clients, we play a key role in strengthening the province’s electrical infrastructures, helping to offer a reliable energy supply for our communities. With our expertise, we tackle the most complex challenges.

We build high-voltage transmission lines ranging from 65 to 735 kV, durable and tailored to our clients’ specific needs.

Our team handles the preventative maintenance of high-voltage transmission lines, ensuring their proper operation and longevity.

We build and renovate transformer substations to meet growing electricity needs. Thanks to our expertise, we optimize network performance and provide a reliable source of electricity.

We work throughout a substation’s entire life cycle, from design to construction, including refurbishment.

We perform essential civil infrastructure engineering work, such as concrete foundations, building renovation, underground pipelines installation, structure assembly, and various foundations construction.

We are focused on the future, where renewable energy will play a key role. We are ready to share our expertise and actively contribute to Quebec’s energy transition by implementing sustainable and innovative solutions.

Over the past few years, we made investments to upgrade and expand our equipment fleet to facilitate work, reach remote locations and provide safe working conditions for our employees. Thanks to these investments, our equipment fleet is now among the largest and best equipped in the industry



We have implemented an effective quality management system to provide a service that meets the needs of our customers while offering a reliable and durable product and strengthening our commitment to excellence.
