ABB awarded $75m refurbishment orders
ABB has won orders worth around $75m from Hydro-Québec, the utility in eastern Canada, and National Grid, the utility in New England, USA, to refurbish three high-voltage direct current (HVDC) converter stations.
The multi-terminal HVDC link between Québec and New England was the world’s first such link to be put into service between 1990 and 1992. ABB will now replace the 20-year-old control and protection systems with the newest modular advanced control systems (MACH) for HVDC equipment.
The link has a total transfer capacity of 2,000 megawatts of power and spans a distance of 1,500km from the La Grande II hydroelectric generating complex near James Bay in eastern Canada, via Nicolet, a substation located on the south shore of the St-Lawrence river, down to Sandy Pond, near Boston, Massachusetts in the US.
