Should they proceed, the projects would have a combined capacity of 3.2 GW and would significantly increase interconnector capacity, which the UK Government, National Energy System Operator, and Climate Change Committee have all highlighted as essential to not only hitting net-zero targets, but also ensuring customers receive low cost and secure power now and in the future. The two projects are forecast to deliver a combined £674 million in benefits to consumers in the first 10 years of their operations.
National Grid Ventures’ participation in these projects is conditional on a final investment decision which amongst other things will require certainty on an acceptable economic regulatory regime for the projects.
Ben Wilson, President of National Grid Ventures said: “Ofgem’s approval of LionLink and Nautilus’ Initial Project Assessment is welcome news, and an important step towards having the regulatory certainty we need to build these projects. It is important that the regulatory arrangements are now finalised and deliver an investible framework. Consumer demand for electricity is set to double in the next 25 years, and if built these interconnectors would provide the invaluable flexibility we need in the system for both now and in 2050. Between them, LionLink and Nautilus would have the capacity to power 4.2 million UK homes, supplying clean, secure, renewable energy and reducing greenhouse gas emissions.”
Manon van Beek, CEO of TenneT added: “LionLink is the first step towards future offshore hubs configured in a meshed offshore DC grid. This hybrid interconnector supports decarbonisation, energy independence/transition and strengthens British, Dutch, and European security of supply. We welcome this big next step in the development of the connection between the UK and the Netherlands. There are still challenges ahead, but we are confident that our joint teams, suppliers and governments will make this project a resounding success.”
Frédéric Dunon, CEO Elia Transmission Belgium, commented: “Nautilus is an important project for our country's energy supply. Because our own offshore wind potential is limited, we need electrical connections to countries that will have surplus wind energy in the future, such as Britain. Nautilus will strengthen our security of supply and provide access to competitive energy prices. This will strengthen the competitiveness of our energy-intensive industry. Because of the hybrid nature of the interconnector, we are also choosing the most efficient solution.”
As a result of this process, National Grid can now confirm that if it proceeds, Nautilus would connect at the Isle of Grain, Kent.
“Community and stakeholder feedback has been essential to the evolution of Nautilus. We have always advocated for the Isle of Grain as the best location for Nautilus given it’s already a major hub for energy infrastructure and has the potential to offer the shortest offshore cable route to Belgium. This view was reinforced by community and stakeholder feedback. Now that Ofgem has approved Nautilus, we will continue to develop the project at Grain and look forward to engaging the community on our plans during future consultation,” concluded Wilson.
