Maritime HVDC link powers up in Nova Scotia

Electricity has been exchanged between the Island of Newfoundland and Nova Scotia through Emera’s Maritime Link Project for the first time this week after seven years of development.

Commissioning Teams from Emera NL and ABB worked together with Newfoundland and Labrador Hydro and Nova Scotia Power to achieve the first successful trial of the Maritime Link. This is a 500 MW HVDC connection that will enable renewable electricity generated in Newfoundland and Labrador to be transmitted to the North American power grid in Nova Scotia.

“Our team has been working closely with the system operators in Nova Scotia and Newfoundland and Labrador, as well as contractors ABB and Nexans for several years to integrate this new interconnection,” said Rick Janega, CEO of Emera Newfoundland & Labrador. “This is a historic accomplishment and the culmination of almost seven years of work from a dedicated team of employees, workers and contractors that have spent countless hours bringing the project to life.”

Commissioning will continue throughout December as the Maritime Link prepares to be ready for customers in early 2018.

The project started in 2013 when ABB won an order worth approximately $400 million from NSP Maritime Link, a subsidiary of Emera, to supply the HVDC transmission system. This uses ABB’s HVDC Light Voltage Source Conversion (VSC) technology incorporating a full VSC bipolar configuration. As well as two converter stations for the ±200 kilovolt (kV) HVDC link, the project also includes two 230 kV alternating current (AC) substations in Newfoundland, one 345 kV AC substation in Nova Scotia and two cable transition stations.
