Significant Energy Infrastructure Projects: Suffolk Coast

Debate between Jenny Riddell-Carpenter and James Naish

Tuesday 16th September 2025 Westminster Hall

[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.

[James Naish (Rushcliffe) (Lab)]

Having worked in the energy industry, I continue to be a strong proponent of local area energy plans, because they would empower communities to make decisions about their own energy needs and how much energy they want to export. At the moment the process feels very reactive and is based on private and landowner interests, as opposed to empowering communities across a local authority area to make decisions. Does my hon. Friend agree that it would be helpful to have energy planning on a statutory footing across every local authority in the country?

[Jenny Riddell-Carpenter]

I know that my hon. Friend has been passionate about this since his arrival in this place last year. I look forward to the Minister’s response to that point, but yes, I do agree; in fact, I will come on to some of those themes later.

There is an opportunity to set up an overarching body to ensure that the many competing schemes, whether already consented, within the development consent order process or in the pipeline, are properly co-ordinated. The body could be departmental or independent from the Government, but it would operate under the direction of the Secretary of State. Although the then Department for Business, Innovation and Skills consulted on the concept of a future systems operator for electricity, that does not go far enough or quickly enough. There needs to be oversight of the cumulative impact of all NSIP schemes in an area. The failings that arise in the absence of such oversight are evident in many areas of my constituency, but are perhaps best highlighted by the case of Boden Farms.

Boden Farms was subject to compulsory purchase of land to accommodate Sizewell C’s development phase, and work has begun on a new relief road on the farm’s former land. The farmer has been told by National Grid Ventures that it, too, will need to access his land in order to lay cables for LionLink. It cannot tell him where, when or if it will be made subject to a compulsory purchase order, but it can tell him that in a year or maybe two it will be digging up the very same land that is being worked on right now by Sizewell C, including, most likely, parts of the new relief road that is being built as we speak.

I am very concerned by reports that the only plans LionLink has ever received for the link road are the ones the landowner provided himself. Surely, that cannot be right, but it is not a one-off; this story is repeated across my constituency, in every parish where lines are being laid or work is being planned. That is in no one’s interest—not the community’s, not nature’s and not even the developer’s—so I tabled an amendment to the Planning and Infrastructure Bill that would have made it a legal requirement for energy developers to co-ordinate their work.

Farmers from Woodbridge to Leiston, and parishes from Friston to Walberswick and Yoxford to Peasenhall, all ask the same thing: why are these projects popping up with no co-ordination, and why is there no legal requirement for them to work together? It is our communities and our environment that have to endure the cumulative impact of all this.

Developers are also failing to put proper mitigations in place or to listen to the concerns of local residents, which is having a real impact. Farmers have told me of issues engaging with energy developers when they have raised objections to cables being buried to a depth of less than 1.8 metres on their land, in breach of electrical safety guidance, leaving them unable to use the land for arable farming. Energy developers have been unwilling to engage, which means that land risks being taken out of arable food production permanently. In laying any cables on active agricultural land, developers should guarantee that arable farmland will be safeguarded for future farming use, and I tabled another amendment to the Planning and Infrastructure Bill that would have made it a legal requirement for energy developers to lay cables to a minimum depth of 1.8 metres.

The depth of cables is an issue not just for farmers, but for offshore shipping. Members will appreciate that I have shipping lanes off the coast of my constituency, and the Harwich Haven Authority has told me that it is concerned that energy developers must do more to engage with it to ensure that cables are buried at a sufficient depth that projects do not compromise navigational safety. The Sunk area around Harwich Haven is a vital and highly complex shipping zone. Any offshore developments must be planned with strict adherence to safety requirements.

The UK has let developers lead the conversation and the strategy. We have ended up with a mismatch of proposals, in the wrong place, with no co-ordination and no desire to think of better alternatives. Other countries are stealing a march. Holistic network design criteria are adopted and adhered to in North sea countries including Belgium, the Netherlands and Germany. As a result, they choose brownfield sites at the outset for their energy infrastructure hubs and, in doing so, manage to avoid adverse impacts on communities and ecologies.

Places such as Zeebrugge and Rotterdam industrial zones are chosen for building substations, with space to build future projects, including hydrogen storage. Those projects are co-ordinated in order to minimise needless damage, maximise efficiencies and move at pace. For the same reasons, energy developers in the UK should be required to pursue as a first option brownfield hubs where multiple projects can co-exist without any adverse impact on nature.

We need to create a legal duty for developers working in the same area to exchange information, seek opportunities for shared infrastructure, reduce cumulative impact and align timelines. A framework of co-ordination, co-design, community benefit and compensation would mean that communities, town and parish councils and the Government could see the whole picture, not just the smallest of fragments. So many of my constituents are devastated by the cumulative impact that these energy projects within a 10-mile radius are having on nature, and no one organisation has ever looked at it.

We can get this right. If we do, we can deliver on our climate ambitions and protect nature at the same time, but it will require greater leadership, oversight and scrutiny, and greater emphasis on making sure that we co-ordinate, plan and implement a clean, green energy revolution that is strategic and not just whack-a-mole. It must be rooted in knowing the land and the geography, and not in the whims of the developer. Getting this right now will mean better protections for our natural environment, better safeguards for our local communities and a lasting legacy for the next generation.
