During WindEurope 2025 in Copenhagen, the TSOs presented the findings of a pilot study , which show that a regional approach to offshore grid development in the Northern Seas can offer both economic and environmental benefits for Europeans.
The report comes with a grid map that outlines promising cross-border projects. These projects are not considered in isolation but as part of a broader offshore regional grid in the Northern Seas, maximizing synergies and cost efficiencies.
The OTC intends to submit a set of these conceptual projects to the Ten-Year Network Development Plan (TYNDP) 2026. The projects could serve as the foundation for joint cost-sharing negotiations between the involved countries, according to the TSOs.
Furthermore, the OTC proposes a regional planning process that could support a government-endorsed regional approach and that would complement existing plans such as the TYNDP and embedded Offshore Network Development Plan (ONDP) and national processes, leading to enhanced coordination and efficiency.
“The OTC would like to highlight that the development of a robust offshore infrastructure is critical for Europe’s energy future. With continued political support and increased collaboration, Europe can advance its ambitious plans for a robust interconnected energy system in the North Sea and position itself as a leader in offshore renewable energy”, the Offshore TSO Collaboration said in a press release on April 9.
