Delivered to NB Power, the upgraded 42-year-old link will enable a reliable power exchange between the New Brunswick and Hydro Quebec grids.
The converter station, which provides a bi-directional asynchronous interconnection in the south-eastern part of Canada, has been upgraded to extend its operational life.
As part of the upgrade program, ABB replaced the existing equipment with the latest converter valves and MACH control and protection system.
ABB Power Systems division HVDC business head Olof Heyman said: "In addition to enhancing grid reliability and power stability, our HVDC solution enables efficient transmission of electricity across this important interconnection.
"ABB’s flexible MACH control system enables the interface with existing equipment on site."
The company also upgraded old valve cooling system from an air-cooled system to a water-cooled system in order to reduce the total valve and cooling system losses by approximately 65%.
NB Power president and CEO Gaëtan Thomas said: "These upgrades will allow our customers to continue experiencing the benefits of this station while helping us keep our rates low and stable over time."
