Under the contract, which was secured from Emera’s subsidiary NSP Maritime Link, ABB will deliver 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 HVDC connection that will bring renewable energy generated in Newfoundland and Labrador to Nova Scotia.
ABB’s HVDC Light Voltage Source Conversion (VSC) technology will be deployed as part of the project and a full VSC bipolar configuration will further improve system availability.
The project will feature two converter stations for the ±200kV HVDC link, two 230kV alternating current (AC) substations in Newfoundland, one 345kV AC substation in Nova Scotia.
The project, which is expected to be commissioned in 2017, will also feature two cable transition stations.
ABB chief executive officer Ulrich Spiesshofer said, "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."
