ABB to link Newfoundland

Power technology group ABB has landed a C$400m ($375m) order from Emera subsidiary NSP Maritime Link for a 520km-long high-voltage direct current (HVDC) transmission link that will connect the Canadian province of Newfoundland to the North American grid.

The 500MW interconnector will use a 200kV HVDC Light voltage source conversion line wired into a pair of converter stations along with two 230kV alternating current (AC) substations in Newfoundland, a 345kV AC substation in Nova Scotia and two cable transition stations.

The Maritime Link project, slated for commissioning in 2017, represents the first electricity link between the island of Newfoundland and the North American power network.

“ABB pioneered HVDC and is a global leader in this key transmission technology which is being increasingly deployed across a range of applications,” says ABB chief executive Ulrich Spiesshofer.

“Our innovative solution for this project will help integrate clean renewable energy, facilitate the efficient transmission of electricity, improve grid stability and enable power sharing.”
