Vattenfall’s Hollandse Kust Zuid 1&2 wind power plant to be fitted with Siemens Gamesa turbines

Siemens Gamesa Renewable Energy (SGRE) and Vattenfall extend Hollandse Kust Zuid turbine supply to cover the entire Hollandse Kust Zuid (HKZ) wind farm zone. Vattenfall will act as launching customer to pioneer Siemens Gamesa’s offshore wind turbine.

At the WindEurope Offshore 2019 Conference & Exhibition in Copenhagen, Vattenfall and SGRE announced that they have agreed to extend the HKZ turbine supply, subject to certain conditions including Vattenfall's final investment decision, to now also include HKZ 1&2 in addition to HKZ 3&4.

The HKZ wind farm zone is planned to be fitted with approximately 140 units of SGRE's upgraded version of its Direct Drive offshore wind turbine, which now features the ability to reach a capacity of 11 MW. This capacity upgrade, available under certain site conditions, means that fewer turbines are needed to generate the same amount of energy. This will reduce installation, operations and maintenance costs and thereby contribute to further reductions in Levelised Cost of Energy for offshore wind. Furthermore, it significantly reduces the environmental impact of installation and operation of the wind farm.

In July 2019, Vattenfall won the tender to build HKZ 3&4. In March 2018, a permit had already been awarded to Vattenfall to build HKZ 1&2. Both tenders were won by Vattenfall with a zero subsidy bid. Once fully operational, HKZ will generate enough power to supply up to 3 million households with green electricity. The development of the wind farm is subject to certain conditions, including Vattenfall's final investment decision.
