The Maritime Link Project is a 500 MW high voltage direct current (HVDC) connection that will enable clean, 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 Canada’s emission-reduction efforts.
“ABB pioneered HVDC and is a global leader in this key transmission technology which is being increasingly deployed across a range of applications” said Ulrich Spiesshofer, ABB CEO. “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.”
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 substations in Newfoundland, one 345 kV AC substation in Nova Scotia and two cable transition stations. The project is scheduled for commissioning in 2017.
Staking its claim
ABB says it has delivered 13 of the 14 commissioned VSC links in the world. This technology is increasingly being deployed across a range of applications, which include: integration of renewable energies from land-based and offshore wind farms, mainland power supply to islands and offshore oil and gas platforms, and city center in-feeds where space is a major constraint and cross-border interconnections that often connect across the seas. Its ability to meet grid code compliance ensures robust network connections regardless of application. 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.
