The Abu Dhabi sovereign investor is increasing its exposure to the infrastructure underpinning Europe’s evolving electricity market.

As countries invest billions in renewable energy, the networks that move electricity across borders are becoming just as important as the power itself.

Mubadala Investment Company (Mubadala) acquired USD 200 million of Equitix’s stake in Greenlink. Greenlink is a joint venture between Equitix and Baltic Cable that operates a 504MW subsea electricity interconnector linking Great Britain and Ireland.

Why You Should Care

The deal highlights a growing investment opportunity in the infrastructure supporting Europe’s energy transition.

As renewable energy capacity expands, power systems require greater flexibility to balance supply and demand across markets. Interconnectors such as Greenlink help move electricity where it is needed most. It strengthens energy security while supporting the integration of renewable energy sources.

For investors, these assets offer exposure to long-term infrastructure trends backed by regulatory frameworks and growing demand for reliable electricity networks.

The Details

Greenlink is a joint venture between Equitix and Baltic Cable. It operates a 504MW high-voltage subsea electricity interconnector spanning approximately 190 kilometers between Ireland and Great Britain. The asset has a nominal capacity equivalent to powering around 380,000 homes.

The project enables cross-border electricity flows between the two markets, helping improve grid resilience, system flexibility, and market efficiency. It also supports the integration of renewable energy by allowing power to move more efficiently across national networks.

Greenlink has been designated a Project of Common Interest by the European Union. This reflects its role in regional energy security and efforts to create a more integrated European electricity market.

“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,”

The acquisition follows Mubadala’s USD 325 million investment in Orsted’s Hornsea 3 offshore wind farm in the United Kingdom. Thus, this investment further expands the fund’s presence in European energy infrastructure.

The Ripple

Mubadala’s investment reflects a broader shift among sovereign wealth funds and institutional investors. This is a shift toward the infrastructure that enables energy systems to function, rather than solely the assets that generate power.

As Europe seeks to strengthen energy security and accommodate rising renewable energy capacity, demand for transmission networks, interconnectors, and grid modernization projects is expected to grow. These assets increasingly support economic activity and help power markets to integrate lower-carbon energy sources.

The transaction also reinforces the attractiveness of regulated infrastructure assets. These assets offer long-term revenue visibility and play an essential role in national energy strategies.

What to Watch

The acquisition suggests Mubadala sees continued opportunity in the networks connecting Europe’s electricity markets.

As governments and utilities invest in grid upgrades and cross-border connectivity, infrastructure investors are likely to increase their focus on assets that improve energy resilience and support renewable integration. Greenlink may prove to be one example of a broader investment theme centered on the modernization of power systems across Europe.
