TenneT has completed the installation of the 900MW DolWin epsilon converter platform in the North Sea.
The three-phase alternating current generated by Orsted’s Borkum Riffgrund 3 offshore wind farm will be converted to direct current on the DolWin epsilon.
The latest milestone comes after the successful installation of the 900MW BorWin epsilon, which will connect to EnBW’s He Dreiht offshore wind farm.
TenneT chief executive Tim Meyerjürgens said: “Just weeks after the successful installation of BorWin epsilon, we have now also completed the installation of DolWin epsilon in the North Sea – another key milestone for TenneT’s offshore expansion.
“Both converter platforms are part of our DolWin5 and BorWin5 offshore grid connection systems, which are due to be commissioned in 2025.
“Together, they will bring TenneT Germany very close to reaching the 10GW mark – a significant step towards securing Europe’s renewable energy supply.
“TenneT has been developing offshore infrastructure for nearly 20 years. In 2010 we commissioned our first 400MW converter platform BorWin alpha. Since then, we have gradually scaled up to today’s 900MW standard – the backbone of current offshore grid connections like DolWin5.”
Borkum Riffgrund 3 is currently the largest offshore wind project in Germany and comprises 83 Siemens Gamesa turbines.
