Global power and automation technology leader ABB has won a $400 million order from NSP Maritime Link Inc. to supply a high-voltage direct current (HVDC) power transmission link in eastern Canada. The HVDC solution will create the first electricity link between the island of Newfoundland and the North American power grid.
Involving the installation of a 500 MW HVDC connection, the Maritime Link Project will enable clean, renewable electricity generated in Newfoundland and Labrador to be transmitted to the North American grid in Nova Scotia. ABB’s latest HVDC Light solution will also allow Nova Scotia to integrate additional renewables and contribute to Canada’s emission-reduction efforts.
According to ABB Chief Executive Officer Ulrich Spiesshofer, ABB is a global leader in the HVDC transmission technology, which is being increasingly deployed across a range of applications. ABB’s solution for the Maritime Link Project will help integrate clean renewable energy, facilitate the efficient transmission of electricity, improve grid stability and enable power sharing. The project will be commissioned in 2017.
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.
ABB’s project scope encompasses two converter stations for the ±200 kV HVDC link, two 230 kV AC substations in Newfoundland, one 345 kV AC substation in Nova Scotia and two cable transition stations.
Pioneered by ABB 60 years ago, HVDC technology is deployed across a range of applications including integration of renewable energies from land-based and offshore wind farms, mainland power supply to islands and offshore oil and gas platforms, city centre in-feeds in space constrained areas, and cross-border interconnections that often connect across the seas. Regardless of application, the technology is able to meet grid code compliance ensuring robust network connections.
ABB has deployed the technology in approximately 90 projects representing a total installed capacity of more than 95,000 MW, accounting for about half of the global installed base.
