Hollandse Kust (west) Alpha Offshore Substation Set for Wind Turbines Link-Up
The grid connection for Hollandse Kust (west) Alpha offshore substation is officially ready for commissioning after receiving grid readiness certificate three months ahead of schedule.This means that wind farm operator Ecowende can connect the wind turbines, which will be located about 50 kilometers off the coast of Egmond aan Zee, to grid operator TenneT's 'socket at sea’ as soon as they are built.Whereas completion was scheduled for the first quarter of 2024, TenneT received the grid readiness certificate from DNV before the holidays in 2023.This makes the grid connection of the
Artificial Reefs Deployed in Dutch North Sea to Boost Marine Life Around Offshore Wind Farms
Dutch transmission system operator TenneT, in collaboration with contractor Equans/Smulders, has installed several artificial reefs near the offshore wind power transformer platform Hollandse Kust (west Alpha), which are meant to stimulate marine life.TenneT said the artificial reefs were installed to gain further knowledge about nature-inclusive construction. This offshore transformer platform will connect the Ecowende consortium (Shell/Eneco) wind farm to the high-voltage grid.TenneT said the aim was to build this wind farm with a healthy ecosystem and as little impact on nature as
DeepOcean Completes Decommissioning Project on Dunlin Alpha Platform
