Developer Vattenfall and grid operator TenneT have signed an agreement for the around 700 MW offshore grid connection for the Hollandse Kust Zuid 3 & 4 offshore wind farm. The connection is planned to become operational in 2022.
Vattenfall won the bid for the offshore wind farm site in July last year after previously also having won the bid for Hollandse Kust Zuid 1 & 2 in 2018. Both tenders were won with a zero subsidy bid. TenneT and Vattenfall signed the agreement for the offshore grid connection for the Hollandse Kust Zuid 1 & 2 in January 2019.
Hollandse Kust Zuid is the second wind farm site where TenneT will provide access in the form of two standardised AC connections of around 700 MW each, following the 1,400 MW Borssele site. The grid connection consists of two offshore transformer platforms which will collect the electricity produced by the individual wind turbines. Via two 220 kV AC cables per platform the electricity is transferred to onshore infrastructure. TenneT is building a new onshore transformer station and is expanding the ‘Maasvlakte 380 kV’ high-voltage station. At this high-voltage station, offshore wind energy is connected to the south ring of the Randstad 380 kV line operated by TenneT. Wind energy is then transferred to power consumers via the national high-voltage network.
The plan is for operations on the connection for Hollandse Kust Zuid 1 & 2 to commence in 2021. The offshore grid connection for plots 3 & 4 will follow in 2022, TenneT said. Hollandse Kust Zuid will feature 140 of Siemens Gamesa’s upgraded Direct Drive offshore wind turbine SG DD-193 which features the ability to reach a capacity of 11 MW.
Offshore construction is scheduled to start in 2022.
