A robot created by Tessellate Robotics is set to begin inspections of Hydro-Québec's transmission infrastructure across the province, according to a statement released on Monday, July 27, 2026. The deployment aims to deliver continuous, day‑and‑night monitoring of the power grid, enhancing the utility's ability to detect issues in real time.
Hydro-Québec manages one of the largest electricity transmission networks in Canada, stretching thousands of kilometres of high‑voltage lines, substations and related assets. Regular visual and technical inspections are essential to maintain safety standards and to ensure reliable delivery of electricity to homes and businesses. The new robotic system will travel along designated routes, using built‑in sensors and imaging equipment to capture data on the condition of cables, towers and other components.
The partnership between Tessellate Robotics and Hydro-Québec reflects a broader shift toward automation in utility maintenance. By operating around the clock, the robot can identify wear, corrosion, vegetation encroachment or other anomalies that might otherwise go unnoticed between scheduled human inspections. The collected information will be transmitted to Hydro-Québec's control centers, where analysts can prioritize repairs and schedule maintenance activities.
Hydro-Québec has emphasized that the robot will complement, rather than replace, its existing inspection teams. Field crews will continue to perform hands‑on assessments and address any findings highlighted by the robotic surveys. The integration of continuous monitoring is expected to reduce response times to emerging faults and contribute to overall grid resilience.
The rollout begins this week, with the robot initially covering high‑risk segments of the network before expanding to additional sections. Both organizations anticipate that the technology will set a new standard for infrastructure oversight in the energy sector, offering a scalable solution for large‑scale transmission systems.
As the robot commences its first routes, Hydro-Québec and Tessellate Robotics will track performance metrics to gauge the impact on maintenance efficiency and system reliability over the coming months.
