ABB has successfully tested the 500 megawatt (MW) high-voltage direct current (HVDC) connection Maritime Link between Granite Canal hydroelectric generating station in Newfoundland and Labrador and Woodbine in Nova Scotia, Canada.

The estimated $1.56bn Maritime Link project is being implemented by NSP Maritime Link (NSPML), a wholly owned subsidiary of Emera Newfoundland and Labrador Holdings and an affiliate of Nova Scotia Power.

Featuring a full-voltage source converter (VSC) bipolar configuration, the HVDC connection is designed to transmit renewable power generated in Newfoundland and Labrador to Nova Scotia and the North American grid.

“Our innovative HVDC Light technology will enable the historical Maritime Link project to integrate and deliver clean renewable energy.”

ABB Power Grids’ grid integration business head Patrick Fragman said: “Our innovative HVDC Light technology will enable the historical Maritime Link project to integrate and deliver clean renewable energy while enhancing grid stability and enabling power sharing.

“HVDC transmission, a technology we pioneered and lead, is an important element of our Next Level strategy, providing customer value and enabling a stronger, smarter and greener grid.”

The project includes two converter stations for the HVDC link and the installation of two 230kV alternating current (AC) substations in Newfoundland and a 345kV AC substation in Nova Scotia with two cable transition stations.

The Maritime Link will allow Nova Scotia to help meet new government regulations that require 40% renewable energy by 2020.

ABB is delivering the HVDC power transmission solution for the project under a contract worth $400m.
