LionLink, which was included as a key project in today’s North Sea Energy Declaration, could connect wind farms to the electricity grids of both countries via a subsea high voltage electricity cable, called a multi-purpose or hybrid interconnector.

National Grid and TenneT have today announced plans for a first-of-its-kind electricity link that will connect offshore wind between the Netherlands and the UK.

LionLink, which was included as a key project in today’s North Sea Energy Declaration, could connect wind farms to the electricity grids of both countries via a subsea high voltage electricity cable, called a multi-purpose or hybrid interconnector. The development would be the first of its kind for the UK and the Netherlands, and the first step towards an integrated electricity grid in the North Sea.

Welcoming the announcement at the North Sea Summit in Ostend (Belgium), UK Secretary of State for Energy Security and Net Zero, Grant Shapps, and Dutch Energy Minister, Rob Jetten, expressed their support for the LionLink project, recognising it as an important step milestone in realising the full potential of the North Sea as Europe’s green energy powerhouse. The UK and EU have a combined target for 110GW of installed offshore wind capacity by 2030, which will make a major contribution to both energy security and climate targets across the region.

LionLink will benefit from the strong and established long-term partnership between the UK and the Netherlands and supports the broader objective of North Sea countries to secure sustainable long term energy security for Europe and the UK by connecting renewables via interconnection.

The British and Dutch energy markets were first connected in 2011 via the BritNed point-to-point interconnector, which has played an important role in supporting energy security this winter.

“It is our conviction that offshore hubs configured in a meshed DC grid must form the backbone of the North Sea powerhouse," said Manon van Beek, CEO TenneT. "This is a view that is increasingly shared, and for us, it is more than a vision of the future. In fact, we are already doing it by kicking off this ground-breaking LionLink project right now. It is a first step and a great opportunity to learn as the offshore grid takes shape. “

Multi-Purpose Interconnector

LionLink is a multi-purpose interconnector, which is designed to link offshore wind farms simultaneously to neighbouring markets via sub-sea interconnectors. Multi-purpose interconnectors will help to accelerate the delivery of offshore wind, while mitigating the impact on coastal communities with fewer individual connections and reduced infrastructure.

LionLink development agreement

Under the terms of the development agreement, TenneT and National Grid Ventures will explore the potential of LionLink, a multi-purpose interconnector (MPI) to simultaneously connect up to 2 gigawatts of offshore wind between the British and Dutch electricity systems. In the next few years, on and offshore studies will commence, including further analysis of existing developments and proposals, as part of an integrated European grid. In the development, phase more research will also be conducted to develop a sound business case and a wider analysis of the socio-economic costs and benefits. The development phase is expected to result in a final investment decision in the middle of this decade.
