ABB has completed a major upgrade of the 350 megawatt (MW) Madawaska high-voltage direct current (HVDC) 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 modernization is expected to significantly improve grid reliability and help reduce maintenance needs.
