ABB to Supply Transformers and Circuit Breakers to Upgrade Quebec Grid

By Editors of Power Engineering Magazine

ABB has won orders totaling more than $85 million to upgrade transmission infrastructure for Canada’s Hydro-Québec (HQ). The contracts will upgrade the utility’s 800-kV air-insulated switchgear substation and transmission grid with circuit breakers, power transformers, and shunt reactors, to support increased demand in the region, along with the integration of new sources of renewable energy.  

Hydro-Québec operates one of the largest 800-kV networks in the world, with much of the network’s infrastructure developed in the 1960s and 1970s. As part of the project, ABB will design, deliver, and commission circuit breakers with polymeric insulators to enhance safety and robustness. It will also design, manufacture, and deliver 450-megavolt-ampere (MVA) autotransformers and 735-kV shunt reactors.

Circuit breakers are a vital component of substations and are essential for safe, reliable, and efficient switching operations. Transformers are integral components of an electrical grid and essential for the efficient and safe conversion of electricity between different voltage systems.

“We are pleased to continue supporting Hydro-Québec, in their ongoing efforts to strengthen Canada’s power infrastructure,” said Claudio Facchin, President of ABB’s Power Grids division. “ABB’s leading-edge technologies will help boost the integration of renewables, deliver additional power, and enhance transfer of electricity over long distances. Ultra-high voltage transmission is a key focus area within our Next Level strategy and a key differentiator for ABB.”
