Hollandse Kust Zuid to use Siemens Gamesa's new 11-MW offshore turbines

Siemens Gamesa Renewable Energy SA (BME:SGRE) will deploy the latest version of its direct drive (DD) offshore wind turbine to all four wind farm projects that Vattenfall AB is planning to build within the 1.5-GW Hollandse Kust Zuid (HKZ) zone in Dutch waters.

Siemens Gamesa on Tuesday presented the new SG 11.0-193 DD Flex offshore wind turbine at the WindEurope Offshore 2019 Conference & Exhibition in Copenhagen and named the Swedish state-owned utility as the first buyer.

The upgraded DD offshore wind turbine can increase its capacity up to 11 MW under certain site conditions. It features a 193-metre diameter rotor with Siemens Gamesa B94 Integral Blades stretching 94 metres.

The order for around 140 units of upgraded turbines is subject to certain conditions, including the final investment decision on the part of Vattenfall, Siemens Gamesa said.

The previous arrangement between Vattenfall and the turbine maker covered the supply of SG 10.0-193 DD machines for the HKZ sites III and IV. The two parties signed a conditional contract even before the Swedish company secured the projects in the Dutch zero-subsidy tender for offshore wind this July.

The conditional order has now been extended to include the HKZ sites I and II, which Vattenfall won in March 2018, and the deployment of Siemens Gamesa's new DD technology.

Offshore works are planned to take place in 2022, while the project is expected to be fully operational in 2023.
