In the midst of an exciting development in sustainable energy, the inaugural caisson of Princess Elisabeth Island is nearing its completion. This pivotal piece marks the initial stride in the construction of the world’s premier artificial energy island—a revolutionary concept in renewable energy infrastructure.
The Vision of Princess Elisabeth Island
An embodiment of innovation, Princess Elisabeth Island is set to become a central nexus for electricity generated by offshore wind farms. This visionary project, not only links these power sources to Belgium but also paves the way for interconnecting energy pathways to the UK and Denmark. Driven by the forward-thinking team at Elia, the pioneer in Belgian electricity transmission, the island promises to be a vital part of the continent’s energy landscape.
Engineering Marvels: The Caissons
At the core of this initiative are the colossal caissons that weigh in at an impressive 20,000 tons each. These massive structures will create the perimeter defense of Princess Elisabeth Island, crafted meticulously at the Dutch facilities of Jan De Nul Group and DEME in Vlissingen. It’s a spectacle of engineering as each caisson’s construction spans approximately three months, intricately divided into a quintet of 20-day intervals. These foundational giants are ushered between workstations by “runners” in an elaborate six-hour relocation process.
The Journey to the North Sea
Upon reaching the pinnacle of construction, the caissons begin their voyage. They’re transported by a semi-submersible vessel to a holding area within the harbor before their ultimate North Sea deployment. This summertime relocation, orchestrated by maritime infrastructure experts at Jan de Nul, is subject to the mercy of the elements.

Princess Elisabeth Zone: A Renewable Powerhouse
Princess Elisabeth Island lies at the heart of the expansive Princess Elisabeth Zone—a prodigious 3.5 GW offshore wind farm sprawling across the North Sea. This futuristic energy hub receives and converts wind-generated power, which is then efficiently transported via subsea cables as high-voltage electricity to Belgium and beyond. Mastering the intricacies of both high-voltage direct current (HVDC) and alternating current (HVAC), the island is a testament to human ingenuity in energy transmission.
The Road Ahead for Princess Elisabeth Island
With an expected completion date set for late 2026, Princess Elisabeth Island will then embark on the installation phase of electrical equipment. This marks the beginning of a new era, as by the year 2030 the island aims to be fully integrated with all connecting wind farms and the mainland, thereby revolutionizing the way we interact with renewable energy sources.
As this ambitious project progresses, it not only represents a significant leap in sustainable energy technology but also a beacon of hope for a cleaner, more resilient energy future for Europe and the world.
