Hollandse Kust Zuid feeds first power to Dutch grid


The Netherlands – The Hollandse Kust Zuid wind farm successfully delivered first power to the Dutch grid.

The first operational turbine is already producing electricity, which is transferred to shore via the alpha offshore transformation station and fed into the grid while still in the testing phase.

Hollandse Kust Zuid construction began last summer, with 34 foundations installed before work was halted for the winter. The second phase, which began this spring, consists of the installation of the remaining foundations, wind turbines, and inter array cables. The first turbine was built during Easter, and 36 more have been added since then. The final turbine will be installed in the second quarter of 2023.

Energy goals

The 225-square-kilometer Hollandse Kust Zuid wind farm is located in the North Sea, approximately 18-35 kilometers off the coast of The Hague and Zandvoort. Each of the SG 11.0 200 DD turbines that will be installed at Hollandse Kust Zuid has an 11-megawatt capacity. The wind farm’s total capacity of 1.5 GW equates to the electricity consumption of approximately 1.5 million Dutch households.

TSO TenneT built two offshore transformer stations to transfer the generated power to the onshore grid. These offshore substations collect all of the power generated by the turbines and transmit it to the Dutch power grid. The 225-square-kilometer wind farm, which is owned by Vattenfall, BASF, and Allianz, is expected to be fully operational in 2023.
