Vattenfall and Siemens Gamesa Renewable Energy (SGRE) have announced that they have agreed to extend the Hollandse Kust Zuid (HKZ) turbine supply, subject to certain conditions including Vattenfall’s final investment decision, to include HKZ 1&2 in addition to HKZ 3&4. This deal creates the largest turbine collaboration to date for Vattenfall.
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 has been uprated to a capacity of 11 MW. Vattenfall will act as launching customer to pioneer what will be Siemens Gamesa’s most powerful offshore wind turbine.
In July 2019, Vattenfall won the tender to build Hollandse Kust Zuid 3&4. In March 2018, a permit had already been awarded to Vattenfall to build Hollandse Kust Zuid 1&2. Both tenders were won by Vattenfall with a zero subsidy bid. The development of the wind farm is subject to certain conditions, including Vattenfall’s final investment decision.
• SGRE announced on 26 November the expansion of its product portfolio with the launch of the new DD Flex concept and the SG 11.0-193 DD Flex offshore wind turbine. Built on the current largest offshore wind turbine in the SGRE fleet, the SG 11.0-193 DD Flex can reach a capacity of 11 MW under specific site conditions.
The uprated WTG features a 193 m diameter rotor utilising the company’s 94 m long B94 integral blades. The upgrade is achieved primarily by the continuous collection of real time operational information and its processing by the control system.
