Arcadis to provide standard design for future 2 GW land stations

TenneT has contracted Arcadis, a global design and consultancy organization for the natural and built environment, to develop and implement a standard design for future 2 GW land converter stations.

The new standard design will be implemented at three locations across the Netherlands. One land station will be located at Borssele in the province of Zeeland and the two others on the Maasvlakte near Rotterdam. The three land stations are the first projects to be delivered in accordance with the new 2 GW standard that TenneT developed to accelerate the roll-out of offshore wind.

The new stations will connect the IJmuiden Ver offshore wind farm. IJmuiden Ver Wind Farm Zone is located 62 kilometers off the west coast of the Netherlands. There will be four wind farm sites which will accommodate 4 GW. A tender to develop sites I and II is scheduled to open in 2023. A tender to develop sites III and IV is scheduled to open in 2025.

Arcadis will manage the detailed design, planning and tender process for the new buildings. The designs will also consider the full life cycle of the asset, including maintenance and operation. The energy generated by the offshore wind turbines will be brought onshore via direct current cables and converted in the land stations into 380 kV alternating current for the high-voltage grid. The high voltage components will be designed and supplied by a specialized company. This contract will initially be worth 4.75 million euros, Arcadis said.

New 2 GW standard

TenneT introduced the new 2 GW standard in 2019. The standard should help reduce the costs of offshore wind and minimizes the impact on space and the environment. Furthermore, capacity will more than double compared to the previous 900 MW HVDC standard that TenneT applied in Germany and almost triples compared to the Dutch 700 MW AC standard for connecting offshore wind farms to the high-voltage grid. With the ambition to accelerate the production of renewable wind energy, future wind farms will be designed to the 2 GW standard. The first grid connection is planned for 2028. Source: Arcadis
