VDC Light system for power transmission link in Maritime provinces will help integrate renewable energy and stabilization of electrical grid, company says
MONTREAL—ABB, a power and automation technology group, has won 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. The project will create the first electricity link between the island of Newfoundland and Labrador and the North American power grid, the company says. The order was booked in the second quarter of 2014.
The Maritime Link Project is a 500 MW HVDC connection that will enable clean, renewable electricity generated in Newfoundland and Labrador to be transmitted to the North American grid in Nova Scotia, said ABB. The stabilizing features of thesolution 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 ABB CEO Ulrich Spiesshofer. “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 (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.
