Summary
Mubadala Investment Company, the Abu Dhabi-based sovereign wealth fund, has acquired a $200 million stake in Greenlink, a subsea electricity interconnector jointly operated by Equitix and Baltic Cable. The transaction represents Mubadala's continued commitment to regulated infrastructure assets that underpin energy transition and grid modernization in developed economies.
Greenlink is a 504-megawatt subsea electricity interconnector spanning approximately 190 kilometers between Ireland and Great Britain. The asset utilizes high-voltage direct current (HVDC) technology, an efficient solution for long-distance power transmission. With nominal capacity equivalent to powering around 380,000 homes, Greenlink operates under dual regulation from Ofgem in the United Kingdom and the Commission for Regulation of Utilities (CRU) in Ireland, providing a structured investment framework with established regulatory oversight.
The interconnector plays a critical infrastructure role in the context of European energy markets. It facilitates cross-border electricity flows, enhances system flexibility by enabling greater renewable energy integration, and strengthens security of supply between two major markets. By connecting wind-rich Ireland with Britain's diverse demand profile, the asset supports market efficiency and reduces reliance on fossil fuel generation during periods of high renewable output.
Mubadala's investment follows the March 2025 acquisition of Greenlink from Partners Group by Equitix and Baltic Cable. This ownership transition consolidates management under experienced infrastructure specialists focused on renewable energy and grid modernization. The sovereign fund's capital deployment underscores institutional investor appetite for regulated, long-duration infrastructure assets that generate stable returns while contributing to decarbonization objectives across Europe's electricity networks.
