ARNHEM, The Netherlands — Tennet announced Aug. 22 that the 49-m-high base for the "socket at sea" Hollandse Kust (west Alpha) has been installed off the coast of Egmond.
The construction weighs 2,300 tons and is secured at the four vertices with the help of piles, which are driven up to more than 50 m into the seabed.
Next year, for this outlet at sea, the ready-made superstructure containing the transformers will be placed on the base.
From 2024, the construction will be ready and will bring sustainable wind energy ashore TenneT with the platform, which has a capacity of 700 MW.
DEME Group stated on its LinkedIn on Aug. 23: "Our DP3 offshore installation vessel Orion successfully completed the installation of the jacket for TenneT’s Hollandse Kust (west Alpha) in the North Sea off the Dutch coast. The offshore substation topside will be installed by DEME Offshore in 2023. The substation is an essential part of the offshore grid and will transmit 700 MW of renewable energy generated by the Hollandse Kust (west Alpha) wind farm to the mainland as from 2024. This was the third offshore wind project carried out with Orion this summer!"
