Significant Energy Infrastructure Projects: Suffolk Coast

Jim Shannon Excerpts

Tuesday 16th September 2025 Westminster Hall

I beg to move,

That this House has considered the coordination of Nationally Significant Infrastructure Projects for energy on the Suffolk coast.

Suffolk Coastal is central to the UK’s energy ambitions. It is often said that up to 30% of Britain’s future energy is expected to be generated in, or transmitted through, my constituency. Suffolk Coastal is home to nationally and internationally important landscapes, including national landscapes, sites of special scientific interest, the Suffolk heritage coast and wetlands that form part of the east Atlantic flyway migratory bird route. Those are not simply scenic features; they underpin local economies and nature-based tourism, and they are vital to national commitments to biodiversity and environmental protection.

As the Minister will be aware, the nationally significant infrastructure projects that I will refer to are being delivered within a small, 10-mile radius, and sit in the heart of those national landscapes, including in nature reserves run by the Royal Society for the Protection of Birds and on important national sites. They stretch from LionLink in Walberswick, which is just south of Southwold, down to Sea Link in Aldeburgh, then next door to Sizewell C, which is Europe’s largest energy project, and link into proposed converter stations in Friston and Saxmundham. Some of those projects have consent while others are going through the process as we speak.

What is remarkable—it is the point of the debate—is the lack of co-ordination between the plans. No attempt has been made to plan for the cumulative impact of the projects or to consider how better to co-ordinate them. In fact, in March 2024, National Grid published details showing that it has no intention to co-ordinate LionLink, led by National Grid Ventures, with the more advanced Sea Link project, led by National Grid Electricity Transmission.

I commend the hon. Lady for introducing the debate. She is right to highlight the issues of coastal communities, where there are very many difficulties. My constituency suffers from coastal erosion, for example, which has been worked on, but there is also the potential to produce clean renewable energy. Does she agree that there is, perhaps, an opportunity for the Minister and the Government to put their minds and money into harnessing that energy for the benefit of all communities throughout the United Kingdom of Great Britain and Northern Ireland?

[Jenny Riddell-Carpenter]

I thank the hon. Member for his contribution, and I look forward to the Minister’s remarks.

As I said, the multiple NSIPs in Suffolk Coastal are within just a 10-mile radius. They are being planned in an area of the country that is mostly served by B roads and country lanes. It seems remarkable that developers are being allowed to bring forward these proposals on some of England’s most important nature sites, when offshore alternatives could easily have been considered. I will focus in this debate on how Suffolk Coastal is being let down and why I am asking the Government to work with me to require the developers to look again at their plans and improve their proposals to minimise disruption to both people and the environment.

As the Minister will know, the previous Government totally vacated the leadership space when it came to our country’s energy and biodiversity planning, and the void was filled by energy developers. They decided to take the lead and were left to make proposals for totally unsuitable landscapes, all because it was cheaper than developing brownfield sites. What we have been left with is a series of unco-ordinated whack-a-mole projects on the Suffolk coast. We have an opportunity under the new Government to provide greater planning and leadership on these critical infrastructure challenges.
