ABB has won an order worth approximately US$ 400 million from NSP Maritime Link to supply a high-voltage direct current (HVDC) power transmission solution creating the first electricity link between the island of Newfoundland and the North American power grid.
The Maritime Link Project is a 500MW high voltage direct current (HVDC) connection that will enable renewable electricity generated in Newfoundland and Labrador to be transmitted to the North American grid in Nova Scotia. The stabilising features of ABB’s latest HVDC Light solution will also allow Nova Scotia to integrate additional renewables. The Maritime Link will deploy ABB’s HVDC Light Voltage Source Conversion (VSC) technology incorporating a full VSC bipolar configuration to further enhance system availability. In addition to the two converter stations for the ±200 kilovolt (kV) HVDC link, the project scope also 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.
