Medium-voltage distribution networks

For over 30 years, Arno has built strong expertise in the construction and maintenance of medium-voltage electrical distribution networks. Our company stands out through its ability to support the ongoing maintenance and expansion of Québec’s electrical grid under provincial contracts, while also responding efficiently to major outages to restore service quickly and safely.

In addition to these essential operations, Arno has successfully delivered several large-scale projects, including:

• Construction of the 34.5 kV line connecting Romaine-3 and Romaine-4
• Rehabilitation of multiple line sections running along a railway corridor on the Côte-Nord
• Development of a new 25 kV distribution line in Inukjuak
• Installation of various medium-voltage lines and metering stations to support industrial sector requirements

These projects have showcased Arno’s leadership within joint ventures and strengthened our capabilities in managing and executing complex worksites—often located in remote or hard-to-access regions. All projects were completed on schedule thanks to close collaboration with our clients and a disciplined project execution approach.
