Belgian transmission system operator (TSO) Elia has developed seven measures to spice up biodiversity round Princess Elisabeth Island, the world’s first synthetic power island.
The unreal Princess Elisabeth Island will likely be an power hub 45 kilometres off the Belgian coast connecting new wind farms and extra interconnections, to the UK and Denmark, to Belgium’s onshore energy grid.
The island will home virtually completely transmission infrastructure used to attach new wind farms of as much as 3.5 GW capability, in addition to future interconnectors.
Protecting six hectares, in the course of the Princess Elisabeth Zone, Princess Elisabeth Island will likely be constructed on concrete caissons full of sand.
The development will take round two years and is predicted to final from March 2024 to August 2026.
Elia partnered with a number of corporations from the character conservation and the marine setting subject to develop Nature Inclusive Design (NID) measures.
Elia stated that ledges will likely be connected to the storm wall on the south, west, and north sides of the power island within the space above the spring tide line, permitting cliff-nesting birds such because the black-legged kittiwake to breed, relaxation, and recuperate.
Subsequent, within the space submerged at excessive tide however mendacity above the water at low tide, the corporate will set up aid panels on the 4 corners of Princess Elisabeth Island. The three-dimensional design of those panels will present a construction to which smaller marine organisms can connect themselves. Smaller fish will even be capable of shelter and forage there, in accordance with Elia.
Larger up on the identical corners, Elia plans to put in longlines with oyster baskets for the European flat oysters. Their larvae might connect themselves to the optimally designed rock revetment across the island, thus selling the expansion of oyster reefs.
“This Nature Inclusive Design marks a significant step ahead within the safety of the marine setting when constructing wind generators in protected marine areas, reminiscent of for the European flat oyster, which is reappearing in Belgium’s a part of the North Sea for the primary time in many years,” stated Paul Van Tigchelt, Minister for the North Sea.

As well as, the corporate plans to create chaotic scour safety with complicated edges across the total island.
In addition to forming a clean connection to the unique gravel beds, this must also create a variety of various habitats the place completely different animal species can forage, shelter, and/or relaxation.
By putting bigger boulders right here and there, Elia will create extra complexity that may make the setting across the island all of the extra engaging to marine organisms, in accordance with the TSO.
Close to the corners and longlines, the corporate will even incorporate oyster tables within the chaotic scour safety, offering a lift for the creation of oyster reefs for the European flat oyster.
By incorporating biodiversityenhancing measures from the design and development part onwards, we goal to increase and speed up optimistic impacts and encourage builders to undertake comparable initiatives. This co-creation mission with consultants has already made an essential contribution to scientific growth on this subject,” stated Nicolas Beck, Head of Group Relations, Elia.
