Power transmission link will facilitate integration of renewable energy and stabilization of electrical grid.
MONTREAL — Power and automation technology group ABB has been awarded an order worth approximately $400 million from NSP Maritime Link Inc., a subsidiary of Emera Inc., to supply a high-voltage direct current (HVDC) power transmission solution to create the first electricity link between Newfoundland and the North American power grid.
The Maritime Link Project is a 500 megawatt 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 stabilizing features of ABB’s latest HVDC Light solution will also allow Nova Scotia to integrate additional renewables and contribute to emission-reduction efforts.
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 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.
ABB pioneered HVDC technology 60 years ago and has been awarded approximately 90 HVDC projects representing a total installed capacity of more than 95,000 MW, accounting for about half of the global installed base.
