Recently, the Great Falls of Sweden announced that it will use Siemens Gamesa SG 11.0-200 DD wind turbines in its Hollandse Kust 1-4 offshore wind power project.

Hollandse Kust 1-4 is located in the North Sea of the Netherlands, with a total installed capacity of 1.5GW. It is part of the Dutch government's goal of completing 4.5GW of offshore wind power by 2023, and is also a zero-subsidy wind farm. The project is expected to start installation in 2022 and put into operation in 2023, when it will become the world's largest offshore wind farm. Therefore, this order has become the largest wind turbine order in history. According to a report submitted by Siemens Gamesa to the Spanish Securities Regulatory Authority, this order included the installation of 140 SG 11.0-200 DD fans in addition to the supply of 140 units.

In fact, at the European Wind Energy Association Marine Industry Conference held in November last year, the two companies reached a conditional agreement, but according to the agreement at that time, the supply model was SG 11.0-193 DD.

At the time of the bidding, Hollandse Kust 1&2 and 3&4 were originally two separate projects. After the two projects were taken up by Great Falls, they decided to merge them into one large project and jointly develop them to achieve scale effect.

After the project is put into operation in 2023, how long it can maintain the title of the world's largest offshore wind farm depends on how Equinor and SSE develop the UK's Dogger Bank project. Dogger Bank's three-phase project is 1.2GW per phase. If it is merged into one project, it will be a super wind farm of 3.6GW. Editor/Peng Xue
