Hydro-Québec to Upgrade 800 kV Substations, Transmission

Sept. 23, 2016
The upgrade is driven by the increasing demand for power and the need to integrate new sources of renewable energy.

ABB has won orders worth over $85 million from Canadian utility Hydro-Québec to upgrade its 800-kV air-insulated switchgear substations and transmission grid with state-of-the-art circuit breakers, power transformers and shunt reactors. The upgrade is driven by the increasing demand for power and the need to integrate new sources of renewable energy.

HQ operates one of the largest 800 kV networks in the world, a large part of which was originally developed in the 1960s and 1970s, and ABB has been involved in the modernization of its power infrastructure over decades.

As part of the project, ABB will design, deliver and commission the state-of-the-art circuit breakers with polymeric insulators, to enhance safety and robustness. It will also design, manufacture and deliver 450 MVA autotransformers and 735 kV shunt reactors.
