hardware flow control. It is an ideal choice in the field of industrial automation.ABB completed commissioning of Maritime Link and officially delivered the power interconnection project
ABB has completed the commissioning of Maritime Link and officially handed over the power interconnection
project to Emera, a leading energy and services company headquartered in Eastern Canada.
The MariTIme Link power interconnection made history on December 8, 2017, with the first power exchange
between Newfoundland and Nova Scotia. It entered service on January 15, 2018, as ABB continues to work
with Emera and the provincial system operators during initial operations.
The Maritime Link is a 500-megawatt high-voltage direct current link that enables clean, renewable energy
produced in Newfoundland and Labrador to
be transmitted to Nova Scotia”s North American grid, reducing reliance on fossil fuels. The robust nature of
ABB”s solution will also enable Nova Scotia to integrate other renewable energy sources, such as wind energy,
and contribute to Canada”s emissions reduction efforts.
ABB officially delivers MariTIme Link power interconnection project
The lightweight HVDC technology used in the Maritime Link design is the world”s first bipolar
configuration using proven and reliable voltage source converters. This solution enhances system availability,
reduces losses and improves grid reliability, allowing power to continue to be transmitted even when a
conductor or converter is not in use. The converter station is equipped with an
advanced MACH control and protection system based on ABB Ability, which functions like the brain of the
high-voltage DC connection, monitoring, controlling and protecting cutting-edge technologies within the station,
and managing thousands of operations to ensure power reliability.
Its advanced fault levels and remote control capabilities also help protect against unexpected outages such as
lightning strikes.
“Our proven lightweight HVDC technology will enable the historic Maritime Link power interconnection
project to integrate and deliver clean renewable energy while enhancing grid stability and enabling power
sharing.” Patrick Fragman, head of ABB”s grid integration business “HVDC is a technology we have pioneered
and led and is an important part of the next phase of our strategy,
cementing our position as the partner of choice for a stronger, smarter and greener grid,” said the company.
In addition to two converter stations for ±200 kV HVDC transmission, the project scope includes two 230 kV
AC substations in Newfoundland, a 345 kV AC substation and two cables in Nova Scotia Transit station.
