Masdar CEO Mohamed Jameel Al Ramahi stated: “This landmark partnership underscores our commitment to driving Europe’s energy transformation and advancing global climate goals. Our strategic co-investments with Iberdrola in East Anglia THREE and Baltic Eagle demonstrate how ambitious cross-border partnerships can deliver transformative impact at scale.
“Together, we are setting a new benchmark for offshore wind collaboration, and we are looking forward to deepening this partnership as Europe accelerates its renewable energy targets.”
Concurrently, the companies announced the full energisation of their 476MW Baltic Eagle project offshore Germany.
Together with the operational 350MW Wikinger and the 315MW Windanker projects currently under development, Baltic Eagle forms part of Iberdrola’s Baltic Hub.
Iberdrola executive chairman Ignacio Galán stated: “Joining forces with Masdar in the East Anglia THREE offshore windfarm will allow Iberdrola to accelerate our strategic focus on the UK, where we are investing £24 billion to 2028 in transmission and distribution networks and in renewable energy, contributing to the delivery of the UK government’s ambitious electrification plans.
“The completion of Baltic Eagle represents a new milestone in our partnership, reinforcing Iberdrola’s commitment to electrification and strengthening our presence in the Baltic Sea.”
In May 2025, Masdar obtained $1bn through the issuance of green bonds, as part of its green bond programme totalling $2.75bn.
