LionLink (formerly Eurolink)

What is LionLink?

LionLink is a proposed High Voltage Direct Current (HVDC) connection between Holland and Suffolk, a joint project between Dutch TenneT (the Dutch Transmission System Operator) and the developer National Grid Ventures (NGV) a non-regulated, for profit company. It is an interconnector cable that will allow for exchange of energy between the UK and Holland, however whereas at the Dutch end wind-farms are connected to their MPI (Multi-Purpose Interconnector platform) to pool the energy offshore, at the UK end there is no offshore integration, with no wind-farms currently planned to connect. This is therefore simply a way for NGV to sell energy for profit when market supply and demand conditions allow for it. See a simple diagram of the Dutch and UK ends of the interconnector HERE

On 6 March 2024 National Grid revealed the preferred landfall sites and cabling routes for the LionLink interconnector between Holland and the UK, with proposed landfall at Southwold or Walberswick. You can read LionLink’s Supplementary Non-Statutory Consultation Report HERE

This makes it more likely that Sea Link an HVDC cable between Suffolk and Kent, will come onshore between Aldeburgh and Thorpeness. SEAS understanding is that Aldeburgh North Warren has been chosen for SEALINK and TWO other schemes. They can only squeeze in two or three M11 width cable trenches through NORTH WARREN RSPB, hence they have to find an additional landfall site further north for LionLink.

SEAS continues on TV, Radio and in the Press to challenge these plans, WATCH our appearance on ITV Anglia on 6 March HERE

READ the arguments against current plans in SEAS Response to the LionLink Supplementary Non-Statutory Public Consultation HERE

SEAS has been promoting a better solution, pooling energy offshore and taking power with subsea cables closer to where it will be used, coming onshore at an existing brownfield site – see our Pilot Tests proposal

These are the wrong plans in the wrong places!

SEAS analysed LionLink’s massive Environmental Impact Scoping Report, and sent its formal response objecting on four counts:
1) Roads and Traffic
2) Tourism and Hospitality
3) Coastal erosion and Geology
4) Biodiversity and Ecology

The Way Forward - A Split Decision
SEAS has called on the Examining Authorities to recommend to the Secretary of State a ‘split decision’ so that:

  1. The offshore turbines are recommended for consent.
  2. The onshore infrastructure is rejected in favour of full consideration of better locations for this infrastructure where the adverse impacts are minimised at a brownfield or industrialised site.
The Way Forward - Offshore Integration

The benefits of an integrated offshore transmission network far outweigh any benefit gained from continuing with a radial transmission system.

Key Documents

East Anglian MPs write to the Minister of State for Energy, Clean Growth and Climate Change calling for an offshore grid. 20 May 2022

Crossed Wires:  Maintaining public support for offshore wind farms, Policy Exchange, July 2021

The Offshore Co-ordination Phase 1 Final Report, NGESO, 16 December 2020, NGESO:  “Adopting an integrated approach for all offshore projects to be delivered from 2025 has the potential to save consumers approximately £6 billion, or 18% in capital and operating expenditure between now and 2050”. Importantly, footnote 5 states, “This means applying an integrated approach to all offshore projects that have not yet received consent”.

Energy White Paper, Powering our Net Zero Future, December 2020

On 6 November 2020, in response to Mr Duncan Baker’s adjournment debate, the then Energy Minister, and now the newly appointed Secretary of State for the Department of Business Energy and Industrial Strategy (BEIS), Mr Kwarteng, made a very encouraging response and said, amongst other things:
- The offshore wind industry had evolved since 2015;
- There was a shift in the industry towards integration.
- Point to point transmission was recognised as having severe detrimental impacts onshore
- Technology was available to build an offshore integrated network
- Industry was engaged through the OTNR
- The argument for some form of offshore network has been won

In July 2020 the Department of Business Energy and Industrial Strategy announced a major Review, the Offshore Transmission Network Review to address the barriers it presents to further significant development of offshore wind, with a view to achieving net zero.

The findings of the Integrated Offshore Transmission Project (East) 2015 Report concluded that an integrated offshore solution was in the interests of the UK as a whole.

It is illogical for further radial connections to the grid to be approved. The acutely detrimental impacts of radial connections must now be properly recognised in the Planning Balance.

Tony Lodge, Centre for Policy Studies believes we need a public inquiry into this energy disaster.

‘Years of ministerial dithering alongside bad planning have helped deliver the perfect storm’

"SASES strongly supports offshore wind and has only taken this action due to the deep flaws in the onshore aspects of these projects and the associated decision making"  SASES

As of early evening on 31 March 2022, ScottishPower Renewables East Anglia One North and East Anglia Two offshore wind projects have been consented.

A difficult time for many and for those directly affected, hard to bear.

We have all challenged and opposed with reason, emotion and determination.  Sadly, our voices did not prevail.

"It is a total disaster for this area and by implication the rest of the UK ... We are suggesting we can find brownfield sites, clean them up and build the hubs there, not in this kind of pristine ancient farm land."

Onshore eyesores that come with offshore wind farms to be shrunk.

Plan to reduce unsightly infrastructure such as cables, substations and pylons in government push to get coastal communities onside.

Legal action threatened over wind farms

Communities in Suffolk are threatening legal action.  SEAS has sent a pre-action protocol letter to Rt Hon Kwasi Kwarteng urging a rethink before seeking permission to apply for a judicial review.

Campaigners 'devastated' after two large wind farms off Suffolk coast given consent.

"This is extremely bad news for the area ... We're thinking about taking this decision to a judicial review."  Fiona Gilmore SEAS

The decision would mean "the devastation of Friston and east Suffolk ... It will mean the loss of 100 acres of farmland at Friston to build the substation."  SASES


Concern over imminent decision on wind farms ...

... we are proud of having renewables at sea. We are very proud of it, but we believe that there are better solutions for the sub-stations, not just for habitats and the environment, but also for the local economy ..."  Fiona Gilmore, SEAS

"We are recommending brownfield sites ... and have requested a split decision ... to prevent the loss of land designated as an Area of Outstanding Natural Beauty ..." Sarah Courage, Kelsale

"Wind energy can be gathered from three or four windfarms at offshore platforms and brought to brownfield hubs ..."  Fiona Gilmore, SEAS

Celebrities speak out against onshore energy hub

"Sir ... A split decision is suggested, to continue building wind turbines but to pivot to offshore integrated cabling to brownfield sites."

Dame Joanna Lumley and actor Ralph Fiennes have warned in a joint letter that two planned wind farms off the Suffolk coast could see an area of beautiful countryside "disappear under a sea of concrete".


The largest onshore energy hub in the UK is anything but green. Developers have chosen an outdated, cheap, easy location for their own benefit. There is a better way forward. Energy can be taken to a brownfield site, closer to London where it is needed.

Green Party, Liberal Democrat and Independent councillors at  East Suffolk Council have said further work should be paused ...

"I understand this is a big challenge for Government and developers but our communities really do need to see some action now, after what has been a lot of talking, it is time to get a grip." 

"If this means calling a pause to further onshore activity until strategic co-ordination is in place, then so be it"  
East Anglian Daily Times, 10 February 2022

At last, a journalist Laura Hughes, has taken time to visit, interview and research in to the particular problems associated with substations and how power from different wind farms can now be integrated at sea and brought to land via a reduced number of cables with brownfield sites used for clustering substations and inter-connectors.
