Mubadala Invests $200 Million in Greenlink, Expanding UAE's European Energy Infrastructure Footprint

Abu Dhabi | EcoPulse24

Mubadala Investment Company has acquired a $200 million stake in Greenlink, a high-voltage subsea electricity interconnector linking Great Britain and Ireland, in a move that further strengthens the UAE sovereign investor's presence in strategic energy infrastructure assets supporting Europe's energy transition.

The investment underscores Mubadala's long-term strategy of building exposure to critical infrastructure platforms that enable more resilient, interconnected, and efficient energy systems.

Strategic Electricity Link Between Britain and Ireland

Greenlink is a 190-kilometer high-voltage direct current (HVDC) subsea electricity interconnector connecting the electricity networks of Great Britain and Ireland.

The project has a transmission capacity of 504 megawatts, sufficient to supply electricity to approximately 380,000 homes, positioning it among Europe's strategically important energy infrastructure assets.

The interconnector is regulated by the UK's Office of Gas and Electricity Markets (Ofgem) and the Commission for Regulation of Utilities (CRU) in Ireland.

It has also been designated as a Project of Common Interest (PCI) by the European Union, reflecting its strategic importance in strengthening regional energy security and integrating European electricity markets.

Supporting Europe's Energy Security and Energy Transition

Greenlink plays a critical role in facilitating cross-border electricity flows, improving grid resilience, and accelerating the integration of renewable energy sources into Europe's power system.

As Europe continues expanding renewable generation capacity, interconnectors are increasingly viewed as essential infrastructure, enabling power networks to balance supply and demand more efficiently while reducing bottlenecks and enhancing energy security.

The project also contributes to market efficiency by allowing electricity to move between regions according to demand conditions, improving overall system reliability.

Mubadala Deepens Its Infrastructure Portfolio

Karim Al Jassar, Head of Infrastructure for Europe, the Middle East and North Africa within Mubadala's Physical Assets business, said the investment reflects the company's continued focus on high-quality infrastructure assets that underpin modern economies and support more interconnected and efficient energy systems.

He described Greenlink as a strong example of infrastructure that combines strategic significance with sustainable economic value, noting that electricity interconnectors are becoming increasingly important as global energy markets evolve.

Ashal Bhuwania, Chief Investment Officer at Equitix, said the partnership with Mubadala reflects a shared vision regarding high-quality strategic infrastructure assets and will help enhance the project's role in supporting interconnected energy markets and facilitating the transition toward lower-carbon energy systems.

A Broader Strategic Shift by Sovereign Investors

For Mubadala, the transaction represents more than a financial investment.

It highlights a broader shift among Gulf sovereign investors toward owning critical infrastructure assets tied to long-term global megatrends, including energy security, decarbonization, and cross-border electrification.

Over the past decade, sovereign wealth funds have significantly increased allocations to infrastructure investments that offer predictable cash flows, inflation-linked characteristics, and long-term strategic relevance.

Electricity interconnectors increasingly fit that profile.

EcoPulse24 Analysis

The Greenlink investment demonstrates how Gulf capital is moving beyond traditional investments in equities and real estate toward acquiring ownership stakes in assets that are becoming indispensable to the global energy system.

For Europe, electricity interconnectors are emerging as strategic assets comparable in importance to pipelines, ports, and transmission networks. As renewable energy generation expands, the ability to transport electricity efficiently across borders is becoming increasingly critical to ensuring energy security and grid stability.

For Mubadala, the transaction reinforces its growing position as a long-term infrastructure investor with exposure to sectors benefiting from structural global shifts.

The investment also offers an attractive combination of regulatory visibility, stable long-term revenue streams, and direct exposure to one of the defining investment themes of the coming decades: the modernization and decarbonization of energy infrastructure.

As energy systems become more interconnected and electrification accelerates worldwide, assets such as Greenlink are likely to become increasingly valuable components of the global infrastructure landscape.
