This is a significant milestone in the energy transition journey of the region. Tim Meyerjurgens, COO TenneT, expressed his delight by saying, “After recent awarding of the first five cable connections and the announcement of the suppliers for the sea- and land-based converter stations, we are again very proud to announce the partners for the multi-year agreement to produce and install the cables for these crucial and innovative grid connection systems for the energy transition. Together, we will deliver around 7000km of HVDC cable for fifteen on- and offshore grid connection systems in Germany and the Netherlands by 2032 with this award alone.”
This contract is a testament to the commitment of TenneT towards the energy transition and its continued efforts to support the growth of renewable energy sources. The innovative grid connection systems will facilitate the integration of large-scale renewable energy into the grid, and pave the way for a sustainable future.
