Siemens has secured a contract from German-Dutch transmission grid operator TenneT for an offshore wind farm grid connection in the North Sea.


Under the deal, Siemens will provide high-voltage direct current (HVDC) technology for the BorWin3 grid connection, while the consortium partner Petrofac will oversee the construction and offshore installation of the project’s platform.

Scheduled for completion in 2019, the 900MW grid connection is the fifth order for Siemens from TenneT.

In addition to constructing the complete HVDC converter on land, Siemens will supply the entire high-voltage equipment of the grid access system.

The company will also provide two power transformers per station at a rating of about 670 MVA and the entire air and gas insulated high-voltage switchgear equipment required for the project.

Siemens Energy power transmission division CEO Karlheinz Springer said that BorWin3 will supply nearly one million German households with clean electricity from wind power.

"We can now fully apply our broad experience gained in our first four pioneer projects in the North Sea to this project," added Springer.
