Borkum Riffgrund 2 substation installed

ØrstedThe offshore substation (OSS) for the  Borkum Riffgrund 2 offshore wind farm has been installed.

"The installation of the substation is the centerpiece of our next German offshore wind farm, Borkum Riffgrund 2. It creates the conditions for us to be able to supply green electricity for the equivalent of another half million German households from next year.

"As high-performance, almost base-loadable, renewable energy, offshore wind is predestined to make a significant contribution to the conversion of our energy supply. And we are part of it,"
says Volker Malmen, Managing Director of Ørsted in Germany.

Hereema Marine Contractors led the installation with the crane ship SSCV Thialf. The offshore substation (OSS) was manufactured by HSM Offshore BV in Schiedam, Netherlands.

The structure weighs about 2500 tonnes and reaches a height of 25m. The jacket foundation for the OSS was installed last year, about 34km off the island of Borkum.

The OSS collects the generated electricity from the 56 8MW wind turbines. Here, the current is transformed before being forwarded to the converter station DolWin Gamma by the grid operator TenneT. There, the incoming electricity is converted into direct current in order to ensure a efficient transport to the mainland.

Around 460,000 German households could be supplied with green energy from the 450MW wind farm once commissioned in 2019.

Ørsted is a key player in the global offshore wind industry and operates around 4.4GW of offshore wind farms worldwide. In Germany, with the Borkum Riffgrund 1, Gode Wind 1 and 2 wind farms already installed and the future Borkum Riffgrund 2, the company can supply the equivalent of approximately 1.4 million German households with electricity each year.
