ABB has completed a major upgrade of the 350 MW Madawaska high-voltage direct current transmission link that connects the grids of Québec and New Brunswick in southeast Canada.The back-to-back converter station has been in operation for more than 30 years and the modernisation is expected to significantly improve grid reliability and help reduce maintenance needs. The project, executed for the leading power utility Hydro-Québec, includes the installation of ABB’s latest generation MACH control and protection system and enhancement of the valves and associated cooling system.
“This upgrade will enhance power availability, reduce outages and improve grid reliability in the region.” said Claudio Facchin, president of ABB's PowerGrids division.
Hydro-Québec has been generating, transmitting and distributing electricity for over half a century. It is Canada’s leading electric utility and among the biggest in North America. Over 40% of Canada’s water resources are in Québec and Hydro-Québec has developed this potential to become one of the world’s largest hydropower producers. Hydro plants generate over 99 % of its electricity.
