National Grid and TenneT Germany have announced plans to develop GriffinLink, a proposed multi-purpose interconnector designed to link offshore wind generation in Britain and Germany and connect it to both national grids.
The companies said the project was unveiled at the North Sea Summit in Hamburg and is intended to support energy security, offshore wind integration and more coordinated infrastructure planning.
GriffinLink would connect offshore wind farms in both countries directly to the British and German power systems, which the partners described as the first multi-purpose interconnector of its kind in Europe.
“We are proud to work with TenneT Germany on this groundbreaking project that will enhance the diversity and flexibility in our energy systems,” Ben Wilson, president of National Grid Ventures, said.
Tim Meyerjürgens, chief executive of TenneT Germany, said the scheme marked an important step in cross-border cooperation. “GriffinLink is the first project of its kind in Europe and will be a major milestone in cross-border energy security,” he said.
The companies said hybrid interconnectors such as GriffinLink enable renewable electricity to flow across borders to where it is most needed, adding that an integrated approach could improve grid utilisation, lower overall costs and reduce impacts on coastal communities and the environment.
UK energy secretary Ed Miliband welcomed the proposal, saying: “These ambitious plans by National Grid and TenneT Germany could deliver further benefits for both Britain and Germany.”
GriffinLink would build on National Grid’s 7.8-gigawatt interconnector portfolio and TenneT Germany’s 23-gigawatt portfolio, the partners said.
The project is expected to enter operation in the late 2030s, supporting offshore wind deployment in the Northern Seas and helping meet rising electricity demand.
