KUALA LUMPUR, May 24 (Bernama) -- Hitachi Energy has been selected by Marinus Link Pty Ltd (MLPL) to supply a high-voltage direct current (HVDC) project of national significance, which will augment the connection between mainland Australia and Tasmania’s grid.
The approximately 345-kilometre cable route HVDC system will enable the flow of renewable power in both directions between the Victorian and Tasmanian states, according to Hitachi Energy in a statement.
“As Australia is rapidly transforming its grid to support the integration of more clean energy sources, we are proud of our HVDC technology that will help transmit large amounts of electricity with higher stability and lower electrical losses.
“Interconnectors like Marinus Link give customers access to affordable, on-demand renewable energy supply and increase storage capabilities,” said Hitachi Energy Managing Director for Grid Integration business, Niklas Persson.
For the first time in Australia, Marinus Link will use advanced converter technology at both ends of the link to stabilise and integrate more renewables into the power grid.
The connection will enable the Tasmanian state to import excess supply of solar and wind produced in Victoria, while reserving its hydro and storing the extra energy. Clean hydropower can then feed the mainland grid when it is needed most, acting as a large battery for the nation.
Hitachi Energy will supply its HVDC Light voltage source converter (VSC) stations in the first stage of the project, which will convert alternating current (AC) to direct current (DC) for efficient, long-distance transmission and DC to AC, where the electricity is returned to the grid.
Upon completion of both project stages, Marinus Link will have a total capacity of 1,500 megawatts (MW), equal to the power needed for 1.5 million Australian homes.
Marinus Link is a project of national significance that will play a fundamental role in the two states’ energy ecosystem in which power infrastructure requires a major overhaul to satisfy the growing electrical demands and guarantee a constant and reliable power flow through Australia’s transition to renewable energy.
Hitachi Energy pioneered commercial HVDC technology 70 years ago and has delivered more than half of the world’s HVDC projects, and currently has the largest installed base of HVDC in the world.
