Switzerland-based ABB is to supply a 500MW HVDC transmission line that will carry renewable energy including hydro from Newfoundland to Nova Scotia.
The $400m deal with NSP Maritime Link, a subsidiary of Emera, will create the first electricity link between the Canadian island and the North American power grid. The project is scheduled for commissioning in 2017.
ABB chief executive Ulrich Spiesshofer said: “Our solution for this project will help integrate clean renewable energy, facilitate the efficient transmission of electricity, improve grid stability and enable power sharing.”
The Maritime Link will deploy ABB’s HVDC Light Voltage Source Conversion technology, incorporating a full VSC bipolar configuration to further enhance system availability.
In addition to the two converter stations for the ±200kV link, the project scope includes two 230kV AC substations in Newfoundland, one 345kV AC substation in Nova Scotia and two cable transition stations.
