Abu Dhabi sovereign investor Mubadala Investment Company has acquired a $200 million (approximately €184 million) stake in Greenlink, a 504-megawatt high-voltage subsea electricity interconnector linking Ireland and Great Britain, in a move that extends the investor's growing footprint in European energy infrastructure, as reported by Gulf News.

Gulf News reported that Mubadala has bought into Equitix's stake in the asset, which is operated through a joint venture between Equitix and Baltic Cable and is jointly regulated by Ofgem and Ireland's Commission for Regulation of Utilities.

Greenlink spans approximately 190 kilometres and uses high-voltage direct current technology, designed for efficient long-distance power transmission. The interconnector has a nominal capacity equivalent to powering approximately 380,000 homes and has been designated as a Project of Common Interest by the European Union, reflecting its role in regional energy security.

The asset supports cross-border electricity flows, facilitates the integration of renewable energy, and provides flexibility to power markets as wind, solar and other low-carbon sources account for a growing share of generation on both sides of the Irish Sea.

Karim El Jazzar, head of Europe and MENA, Infrastructure at Mubadala, said: "As power markets evolve, interconnectors are becoming increasingly important in supporting cross-border electricity flows and facilitating the integration of renewable energy and grid stability. Our partnership with Equitix delivers on this strategy by strengthening regional connectivity and supporting the energy transition across European markets."

The deal aligns with Mubadala's broader strategy of investing in regulated infrastructure assets underpinned by long-term demand, energy security requirements and the global shift toward lower-carbon power systems.

The Greenlink investment follows Mubadala's $325 million commitment to the Hornsea 3 offshore wind project in the UK, indicating a sustained appetite for large-scale European energy infrastructure assets. Mubadala has also recently backed Central and Eastern European renewables through a €300 million deal, further broadening its European energy portfolio.

The transaction underscores the increasing role of sovereign wealth funds and long-term institutional investors in financing the energy transition infrastructure required to connect renewable generation with demand centres across Europe.
