ABU DHABI, 16th June, 2026 (WAM) — Mubadala Investment Company (Mubadala) has acquired $200m of Equitix’s stake in Greenlink, a joint venture between Equitix and Baltic Cable which operates a 504MW subsea electricity interconnector linking Great Britain with Ireland. This investment reflects Mubadala’s continued focus on infrastructure assets that support more connected, efficient, and resilient power systems.
Greenlink is a high-voltage subsea interconnector spanning approximately 190km between Ireland and Great Britain. Regulated by Ofgem and CRU, the asset utilises high-voltage direct current (HVDC) technology, which is efficient for long-distance power transmission, and has a nominal capacity equivalent to powering around 380,000 homes.
It plays a critical role in supporting the integration of renewable energy, enhancing system flexibility, and facilitating cross-border electricity flows while strengthening security of supply, improving market efficiency and reinforcing connectivity with the wider European energy market.
Greenlink has been designated as a Project of Common Interest by the European Union, reflecting its importance to regional energy security and a more integrated European power market.
The investment is underpinned by a well-established regulatory framework, providing long-term visibility on revenues and reinforcing the asset’s role as essential infrastructure within both markets.
By addressing evolving supply and demand dynamics across the Irish and UK power markets, Greenlink is positioned at the intersection of the energy transition and infrastructure modernisation, aligning with Mubadala’s strategy of investing in assets linked to global megatrends and partnering with leading platforms.
Karim El Jazzar, Head of Europe and MENA, Infrastructure, Mubadala, said, “This investment reflects our continued focus on high-quality infrastructure assets that are integral to the functioning of modern economies, including those enabling more connected and efficient energy systems. Greenlink is a strong example of infrastructure that combines strategic relevance with a clear and sustainable economic value. 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.”
Achal Bhuwania, CIO at Equitix, stated, “We are pleased to partner with Mubadala on this investment in Greenlink, which reflecting our shared focus on high-quality, strategically important infrastructure. Bringing together two investors with deep infrastructure expertise strengthens the platform and positions it well to support the evolving needs of interconnected power markets. Greenlink is a critical asset, enhancing energy resilience, enabling cross-border connectivity and supporting the transition to a lower-carbon energy system.”
