France-based firm Alstom has delivered and installed two 700MVA power transformers for the 900MW grid connection project, DolWin3 offshore of Germany.
Dutch transmission system operator TenneT had awarded the project to Alstom in February 2013, to connect North Sea wind farms to the mainland supergrid.

The equipment was deployed on the substation platform at the Nordic Yards dockyard in Warnemünde, which is operated by Nordic Yards.
Alstom designed and manufactured the transformers specifically for the project at its Mönchengladbach facility in Germany.
The Dolwin3 grid connection project is scheduled to be completed in 2017.
Installed transformers for the offshore platform weigh about 500t each and can ensure uninterrupted transmission of energy from the converter platform.

By GlobalDataTenneT Offshore Management member Wilfried Breuer said: "With the grid connection DolWin3, we will provide a total of about 7,000MW connectivity in the North Sea, transporting offshore wind power to the shore.
"This is equivalent to the supply of about nine million households with green energy.
"The German Government’s offshore-expansion target for the North Sea and the Baltic Sea of 6,500MW until 2020 will be fulfilled early."
Nordic Yards CEO Herbert Aly said: "The 900MW wind energy DolWin 3 is the most powerful and largest HVDC-converter platform built at Nordic Yards."
