Dutch-German TenneT pushes for giant 12 GW NSWPH [free access]

September 15, 2020

The Dutch-German transmission system operator (TSO) TenneT, at a high-level European panel, has indicated that the giant 12 GW North Sea Wind Power Hub (NSWPH) could be built in the early 2030s.


The NSWPH, being developed by a consortium of TenneT, Denmark’s TSO Energinet, and Dutch natural gas infrastructure and transportation company Gasunie and Port of Rotterdam, is an important, possible alternative path of an internationally coordinated roll-out towards accomplishing Europe’s green energy transition and achieving the Paris Agreement.


As per reports, the whole system may function as a hub for the transport of wind energy, an interconnection hub to the connected countries, a working hub for offshore wind developers, and a location for possible power-to-gas solutions. This project is the first building block of the hub-and-spoke concept connecting up to 12 GW future offshore wind parks to the systems of Denmark, the Netherlands and Germany. An integral part of the NSWPH is to assess the perspectives of coupling large-scale wind power production with the gas system through power-to-gas (PtG) technology.


The NSWPH is not yet included in the last national development plans of Denmark, Germany or the Netherlands, and therefore, the additional internal, required grid reinforcements are presently still being analysed in various feasibility studies at a wider regional level. It builds on long-term system needs also identified in the European Network of Transmission System Operators for Electricity (ENTSO-E) Regional Investment Plan North Sea. Due to the strong internationally coordinated drive of this project, the concept was first addressed in ENTSO-E’s ten-year network development plan (TYNDP) 2018 process.
