NSP Maritime Link Inc. has awarded ABB a $400 million contract to supply a high voltage direct current (HVDC) link connecting the island of Newfoundland and Nova Scotia.
The 500 MW interconnection will be the first linking the grids of Newfoundland and North America. It will enable renewable electricity generated in Newfoundland and Labrador to be transmitted to the North American grid via Nova Scotia.
The Maritime Link will deploy ABB’s HVDC Light Voltage Source Conversion (VSC) technology incorporating a full VSC bipolar configuration to enhance system availability.
In addition to the two converter stations for the ±200 kV HVDC link, ABB’s project scope includes two 230 kV alternating current (AC) substations in Newfoundland, one 345 kV AC substation in Nova Scotia and two cable transition stations. The project is scheduled for commissioning in 2017.
