Abu Dhabi investor takes stake in Greenlink amid growing pressure on power grids due to rising electricity demand.
Dubai: Mubadala Investment Company has purchased $200 million of Equitix’s stake in Greenlink, a subsea electricity interconnector connecting Great Britain and Ireland, in a deal that strengthens the Abu Dhabi sovereign investor’s footprint in European energy infrastructure.
Greenlink is a 504-megawatt high-voltage subsea interconnector stretching around 190 kilometres between Ireland and Great Britain. The asset is operated through a joint venture between Equitix and Baltic Cable and is regulated by Ofgem and Ireland’s Commission for the Regulation of Utilities.
Greenlink uses high-voltage direct current (HVDC) technology, designed for efficient long-distance electricity transmission. Its nominal capacity is equivalent to powering around 380,000 homes, giving it a key role in supporting electricity flow between the UK and Ireland.
The interconnector enables cross-border electricity transfers, supports the integration of renewable energy, and improves flexibility in balancing supply and demand. This is becoming increasingly important as more wind, solar, and other low-carbon sources are added to the grid.
Greenlink has been designated as a Project of Common Interest by the European Union, highlighting its role in strengthening regional energy security and advancing a more integrated European power market.
Mubadala expands energy infrastructure push
The transaction aligns with Mubadala’s strategy of investing in infrastructure assets tied to long-term global trends, including the energy transition, modernisation of power grids, and the development of more resilient energy systems.
“As power markets evolve, interconnectors are becoming increasingly important in supporting cross-border electricity flows and enabling the integration of renewable energy while enhancing grid stability,” said Karim El-Jazzar, Head of Europe and MENA, Infrastructure at Mubadala. “Our partnership with Equitix delivers on this strategy by strengthening regional connectivity and supporting the energy transition across European markets.”
The investment also reflects Mubadala’s growing focus on regulated infrastructure assets, where long-term demand is underpinned by energy security needs and the global shift toward cleaner power.
