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 (SIX: ABBN) 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 MW of power and spans a distance of 1,500 KM 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.

The project scope also includes refurbishment of two cable transition stations and a control and protection system replica for a test center in Canada. The stations are scheduled to go in operation in stages and will be completed by 2016.

The MACH system is the world’s most extensively deployed control solution for HVDC and Flexible Alternating Current Transmission Systems (FACTS) installations, with over 1,100 such systems in operation throughout the world.
