77 kilometers off the north coast of the Netherlands and will be the first wind farm to connect to the Eemshaven.The total wind farm area is approximately 580 km2 and is planned to contain a total capacity of 4 GW divided over two sites of 2 GW each.Petrofac and Hitachi Secure Second Contract with Tennet for Offshore Converter Station
Hollandse Kust (west) Alpha Offshore Substation Set for Wind Turbines Link-Up
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 'socket at sea' to the national electricity grid
Jan De Nul Inks Two Contracts with TenneT
Jan De Nul Group together with its consortium partners LS Cable & System and Denys has signed the contracts for two 525 HVDC cable systems for the two grid connection systems BalWin4 and LanWin1. These mark the first two contracts signed under the long-term framework agreement that TenneT and Jan De Nul have signed earlier this year. The projects comprise the design, manufacturing, transport, installation, protection and testing of three 525 kV cable systems for connecting offshore wind farms to the onshore grid via the BalWin4 and LanWin1 grid connections.Jan De Nul will take care of the transport
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

that this allows the vessel to handle “bundled” HVDC cable systems and install them up to a water depth of 4 m with full DP capabilities. The Atalanti will be equipped with the jet-sled Hydroplough burial tool, ensuring that the protection of the cable system will be reached following TenneT’s requirements.Marine operations are scheduled to be executed during 2025.Credit: Asso.subseaMcDermott Starts Construction of TenneT's BorWin6 HVDC Converter PlatformTenneT Taps Nexans for BorWin6 Cable
Jan De Nul and Hellenic Cables to Deliver Offshore Cables for German Offshore Wind Projects
Offshore installation firm Jan De Nul Group, in partnership with power cable maker Hellenic Cables, has won a contract from TenneT for the turnkey delivery of three HVAC offshore grid connection cables for the offshore wind farms to be developed in zones N-3.7 & N-3.8 in Germany. These cables will connect the wind farms to the DolWin kappa converter station, from which HVDC cables transfer the produced energy to shore.The turnkey contract, with delivery anticipated in 2026, consists of three 155 kV HVAC grid connection cables. A single cable is installed between zone N-3.7 and the DolWin
Second Sea Cable Lay for 'West Alpha' Completed
Jan de Nul Group/LS Cable & System has completed the installation of the second subsea cable for the offshore wind farm 'west Alpha' completed. In recent weeks, more than 60 km of cable have been laid in the seabed between the beach of Heemskerk and the 'socket' that grid manager TenneT is having built at sea.Last summer, Jan de Nul pulled four sea cables from the beach of Heemskerk in conduits under the dunes. After the installation of the two sea cables for the Hollandse Kust (north) wind farm, the first kilometers of the two cables for 'west Alpha' were laid capped in
