Japanese Companies To Invest GBP 14.2 Billion In UK’s Offshore Wind, Green Hydrogen

The title of this post, is the same as that of this article on

This is the sub-heading.

Japanese giants Marubeni Corporation, Sumitomo Corporation, and Sumitomo Electric Industries have committed to investing a total of GBP 14.2 billion (approximately EUR 16.3 billion) in offshore wind and green hydrogen projects, and the offshore wind supply chain in the UK

These two paragraphs add a bit of context and flesh to the deal.

Ahead of the UK Prime Minister’s business reception in Tokyo on 18 May, the UK government announced that leading Japanese businesses have committed to invest GBP 17.7 billion (approx. EUR 20.3 billion) in businesses and projects across the UK.

Of this, GBP 14.2 billion has been committed by Marubeni, Sumitomo and Sumitomo Electric for projects in offshore wind, green hydrogen and offshore wind supply chain.

SSE’s Berwick Bank Wind Farm will have a capacity of 4.1 GW and is budgeted to cost just short of £18 billion. Doing a quick calculation, indicates that £14.2 billion would only finance £3.23 GW of offshore wind.

But the Japanese say they will invest in offshore wind, green hydrogen and offshore wind supply chain. Investing in the offshore wind supply chain, would surely attract more money as the developers placed orders for foundations, floaters, electrical gubbins and support vessels.


  1. In Japanese Giant Sumitomo Heavy Invests In Liquid-Air Energy Storage Pioneer, I wrote about Sumitomo’s investment in English energy storage. company; Highview Power.
  2. Electrolyser company; iTM Power has also sold a 1.4 MW electrolyser to Sumitomo and signed an agreement over American sales with another Japanese company.

I can see other similar co-operative deals being developed. Possible areas could be cables, transformers and support vessels.

Largest Offshore Wind Project In UK Reaches Development Milestone

The title of this post, is the same as that of this article on

This is the sub-heading.

An application to build the up to 4.1 GW Berwick Bank, the UK’s largest offshore wind farm, capable of providing enough electricity to power more than five million homes, has commenced determination, SSE Renewables said.

These two paragraphs outline the current status of the project.

Located roughly 38 kilometers off the East Lothian coast of Scotland, Berwick Bank is the largest offshore wind farm planning application to be submitted in the UK to date and one of the largest globally.

The consent process for the onshore elements of the project has now opened, which is being considered by East Lothian Council.

This process runs alongside the offshore consent process, which kicked off in December 2022 and is being considered by the Scottish Government. A final decision by authorities is expected later in 2023.

SSE Renewables hope to deliver first power by 2027.

Berwick Bank Wind Farm Could Provide Multi-Billion Pound Boost To Scottish Economy And Generate Thousands Of Jobs

The title of this post, is the same as that of this press release from SSE.

This press release is all about numbers.

  • 307 turbines
  • 4.1 GW nameplate capacity
  • 5 million homes will be powered
  • 8 million tonnes of carbon dioxide avoided
  • Up to £8.3 billion to the UK economy
  • 4650 potential jobs in Scotland
  • 9300 potential jobs in the UK

These are all large figures.

This map from SSE shows the location of the wind farm.

The press release says this about connections to the grid.

Berwick Bank has secured a grid connection at Branxton, near Torness, in East Lothian. A second grid connection will be required for the project, which has been determined as Blyth, Northumberland.

Note, that Torness is the site of Torness nuclear power station.

  • It has a nameplate capacity of 1.29 GW.
  • It is scheduled to be shutdown in 2028.

This Google Map shows the coast between Dunbar and Torness nuclear power station.


  1. The town of Dunbar is outlined in red.
  2. The yellow line running diagonally across the map is the A1 road.
  3. Torness nuclear power station is in the South-East corner of the map to the North of the A1.

This second Google Map shoes an enlargement of the South-East corner of the map.


  1. Torness nuclear power station at the top of the map.
  2. The A1 road running across the map.
  3. The East Coast Main Line to the South of the A1.
  4. Innerwick Castle in the South-West corner of the map.

This Google Map shows the location of Branxton substation in relation to Innerwick Castle.


  1. Innerwick Castle is in the North-West corner of the map.
  2. Branxton substation is in the South-East corner of the map.

I estimate that the distance between Torness nuclear power station and Branxton substation is about five kilometres. The cable appears to be underground.

I have some thoughts.

Will The Connection Between Berwick Bank Wind Farm And Branxton Substation Be Underground?

If SSE follows the precedent of Torness nuclear power station, it will be underground.

Or will they use T-pylons?

This page on the National Grid web site is entitled What’s A T-Pylon And How Do We Build Them?.

From an engineering point of view, I suspect T-pylons could be used, but aesthetics and local preference may mean the cable is underground.

It should be noted that Torness nuclear power station will be shutdown in 2028. So will the current underground cable for the nuclear power station be repurposed after shutdown for the Berwick Bank wind farm?

This would mean, that the Southern connection cable to Blyth could be built first to support the first turbines erected in the wind farm.

When Will Berwick Bank Wind Farm Be Commissioned?

This page on the Berwick Bank wind farm web site is a briefing pack on the project.

The page gives construction and commission dates of 2026-2030.

Will There Be A Battery At Torness?

As we are talking about the latter half of the current decade for completion of the Berwick Bank wind farm, I believe that a substantial battery could be installed at Torness to smooth the output of the wind farm, when the wins isn’t blowing at full power.

One of Highview Power’s 2.5 GW/30 GWh CRYOBatteries could be about the right size if it has been successfully developed, but I am sure that other batteries will be of a suitable size.

If there is a case for a battery at Torness, there must surely be a case for a battery at Blyth.

Will Berwick Bank Wind Farm Be A Replacement For Torness Nuclear Power Station?


  • Torness nuclear power station is shutting down in 2028.
  • Berwick Bank wind farm will be fully operational by 2030.
  • Berwick Bank wind farm could use a repurposed connection to Branxton substation, if the nuclear power station no longer needs it.
  • There is space on the Torness site for a large battery.

, it looks like Torness nuclear power station could be replaced by the larger wind farm.

Wind Farms On The East Coast Of Scotland

This map shows the proposed wind farms off the East coast of Scotland.

There are five wind farms in the map.

  • The green area is the cable corridor for Seagreen 1a
  • Inch Cape is the odd-shaped wind farm to the North and West of the green area
  • Seagreen at the top of the map, to the North of Inch Cape.
  • Marr Bank with the pink NE-SW hatching
  • Berwick Bank with the green NW-SE hatching
  • Neart Na Gaoithe is edged in blue to the South of the green area.

Berwick Bank and Marr Bank are both owned by SSE and appear to have been combined.

These are some more details on each of the now four wind farms.


These are details of the Seagreen wind farm.

  • Seagreen will be Scotland’s largest and the world’s deepest offshore wind farm when complete.
  • The first phase will have 114 turbines and a capacity of 1075 MW.
  • It will connect to the grid at a new substation at Tealing near Dundee.
  • The cables will run to the North of the Inch Cape wind farm.
  • It will be completed in 2023.
  • The second phase (1a), will have 36 turbines.
  • It may have larger turbines.
  • The cables will run in the green area to Cockenzie in East Lothian.

This press release from SSE is entitled Another Milestone For Scotland’s Largest Offshore Wind Farm As 4,800 Tonnes Offshore Platform Completed.

This is the first paragraph.

The topside forms the backbone of the offshore wind farm. At 40 metres long, 45 metres wide and 15 metres high, the heavyweight superstructure’s role is to collect and manage 1,075MW of power generated by the 114 Vestas wind turbines before transferring it ashore via around 60km of offshore subsea cabling.

This platform is used to connect the 114 turbines to the shore.

Inch Cape

This paragraph from the home page of the Inch Cape web site, describes the wind farm.

The Inch Cape Offshore Wind Farm, currently in late stage development, will see up to 72 turbines located 15 km off the Angus Coast and connect to the National Grid at Cockenzie, East Lothian. Once complete, it will be one of Scotland’s largest single sources of renewable energy and power up to 1 million homes with clean electricity.

The home page says it will generate up to 1 GW of electricity.

Neart Na Gaoithe

This sentence for the Wikipedia entry for the Neart Na Gaoithe web site describes the wind farm.

It is being developed by Mainstream Renewable Power at a cost of £1.4bn. Offshore work began in 2020, with completion planned for 2023.

The Wikipedia entry says it will generate up to 450 MW of electricity.

Berwick Bank

These two paragraphs from the project page of the Berwick Bank web site describes the wind farm.

Located in the North Sea, in the outer Firth of Forth, Berwick Bank Offshore Wind Farm has the potential to deliver up to 4.1 GW of installed capacity, making it one of the largest offshore opportunities in the world.

Berwick Bank Wind Farm is in the development stage and previously the project was comprised of two separate proposals, Berwick Bank Wind Farm and Marr Bank Wind Farm. Following initial rounds of consultation, it has been decided to combine our proposals into one single opportunity – Berwick Bank Wind Farm.

At 4.1 GW,  Berwick Bank is a big wind farm.

The capacity of the four farms can be summarised as follows.

  • Seagreen – 1075 MW
  • Neart Na Gaoithe – 450 MW
  • Inch Cape – 1000 MW
  • Berwick Bank – 4100 MW

This gives a total of 6625 MW.
