MONTREAL – ABB has won an order worth approximately $400 million from NSP Maritime Link to supply a high-voltage direct current (HVDC) power transmission solution. It’ll be the first electricity link between Newfoundland and the North American power grid.
The project will give Nova Scotia access to more renewable energy, stabilizing the price, and, for the first time in the province’s history, the ability to sell energy.
“This is an important new chapter in the power transmission industry for Canada and North America,” said Anders Hultberg, senior vice president, Power Systems for ABB in Canada.
The Maritime Link Project is a 500 MW high voltage direct current (HVDC) connection that see renewable electricity generated in Newfoundland and Labrador to be transmitted to the North American grid in Nova Scotia. There will be two converter stations installed for the ±200 kV HVDC link, and also includes “two 230 kV alternating current (AC) substations in Newfoundland, one 345 kV AC substation in Nova Scotia and two cable transition stations,” ABB explained. ABB’s HVDC has already been commissioned in 13 of the 14 VSC links in the world. The Maritime one is set to be commissioned in 2017.
ABB’s HVDC will also let Nova Scotia integrate additional renewables. The technology is being used in a range of areas, ABB said, including the integration of renewable energies from land-based and offshore wind farms, mainland power supply to islands and offshore oil and gas platforms, city center in-feeds and cross-border interconnections.
