DolWin epsilon installed in North Sea
Energy Disrupter
General – Grid Connection
Tim Meyerjürgens, CEO TenneT Germany announced on Social Media, that TenneT has now also completed the installation of DolWin epsilon in the North Sea.

Recently, the BorWin converter platform was already installed.
Both converter platforms are part of the 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 10 GW mark.
TenneT has been developing offshore infrastructure for nearly 20 years. In 2010 TenneT commissioned its first 400 MW converter platform BorWin alpha. Since then, the system operator has gradually scaled up to today’s 900 MW standard – the backbone of current offshore grid connections like DolWin5.
Meyerjürgens: “The next technological leap is already in preparation: Tennet’s 2GWprogram will further increase efficiency and system performance. But this is not just about capacity. Efficiency, interoperability and European coordination must go hand in hand. That’s why we are investing in multi-terminal hubs and a future cross-border HVDC Overlay Grid, to enable a truly integrated offshore system.”
Planning for 70 GW of offshore wind in the North and Baltic Seas by 2045 is ambitious – and necessary for reaching climate goals. But a shift is needed: from pure capacity targets to realistic energy goals. System efficiency must become a guiding principle through coordinated targets, shared standards, and smart spatial planning.
