Abu Dhabi–based Mubadala Investment Company has acquired a $200 million stake in Greenlink from Equitix, marking a significant secondary investment in the subsea energy sector.
Greenlink is a joint venture between Equitix and Baltic Cable that operates the 504MW subsea electricity interconnector linking Great Britain and 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 utilizes 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.
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.
Karim El Jazzar, Head of Europe and MENA, Infrastructure, Mubadala, said that, “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,” Jazzar added.
Achal Bhuwania, CIO at Equitix, stated that, “We are pleased to partner with Mubadala on this investment in Greenlink, which reflects 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.”
According to the statement, the investment further expands Mubadala’s presence in European energy infrastructure and underscores its partnership-led approach to investing in assets that support more efficient and sustainable energy systems globally.
