Siemens Gamesa Renewable Energy (SGRE) will supply its latest 11 MW offshore wind turbine for Vattenfall’s Hollandse Kust Zuid (HKZ) wind farm. The news was announced at the WindEurope Offshore event in Copenhagen.
SGRE already had a turbine supply agreement in place with Vattenfall for HKZ 4 & 4. This agreement has now been extended to also include HKZ 1 & 2. Vattenfall will be the launching client for SGRE’s 11 MW platform that was officially launched at the same event.
The entire 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, the SG 11.0-193 DD Flex, which now features the ability to reach a capacity of 11 MW. The SG 11.0-193 DD Flex offshore wind turbine features a 193 m diameter rotor utilising the 94-m long Siemens Gamesa B94 Integral Blades.
According to SGRE, the 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 Levelized Cost of Energy for offshore wind.
Vattenfall was awarded the permit for HKZ 1 & 2 in March 2018 and for HKZ 3 & 4 in July of this year, based on a zero subsidy bid. The development of the wind farm is subject to certain conditions, including Vattenfall’s final investment decision. Installation is planned for 2022 while the project is expected to be fully operational in 2023.
