LineRanger is an innovative solution for inspecting power transmission lines.


LineDrone is a drone prototype specialized in direct-contact inspection of high-voltage transmission lines.


LineScout is a robotic platform designed to inspect energized transmission lines and carry out minor repairs.


LineROVer is a remotely-operated robot designed to inspect energized transmission and distribution lines and carry out minor repairs.


LineCore is a corrosion detector that provides detailed information about the condition of the galvanic protection on transmission and distribution line conductors.


The Scompi system offers an alternative to replacing and factory-refurbishing turbines. It is also able to perform in situ repairs of guide rails and spherical valves.


Our 3D inspector of vertical surfaces, the WireScan robot measures the geometry of surfaces and long vertical sections above and below the waterline.


Infrastructure refurbishment, equipment replacement, maintenance project prioritization and investment decisions must be based on accurate strategic information.

As the owner of a power grid and generating facilities, you face many challenges: aging assets, growing demand and proliferating operating constraints. To help you maintain your facilities to the highest standards, Hydro-Québec offers a range of technological solutions to guide you to the best asset management decisions.


Anticipating the evolving condition of your equipment lets you take action at the optimal time. For this, you need reliable data.

The prevention solutions developed by Hydro-Québec provide unparalleled data quality. Whether you’re diagnosing the condition of a transmission line conductor, visualizing the condition of a head gate slot or modelling the damaged profile of a turbine runner, our technologies give you access to the best prevention data on the market.


Some interventions cannot wait — and at the same time, must have little to no impact on energy delivery.

Hydro-Québec’s solutions make it possible to perform in situ interventions with previously unimaginable efficiency and safety while maximizing equipment availability.
