The Anonymous Widower

RWE And the Norfolk Wind Farms

In March 2024, I wrote RWE And Vattenfall Complete Multi-Gigawatt Offshore Wind Transaction In UK, which described how Vattenfall had sold 4.2 GW of offshore wind farms, situated off North-East Norfolk to RWE.

This map from RWE shows the wind farms.

Note.

  1. The Norfolk Zone consists of three wind farms; Norfolk Vanguard West, Norfolk Boreas and Norfolk Vanguard East.
  2. The three wind farms are 1.4 GW fixed-foundation wind farms.
  3. In Vattenfall Selects Norfolk Offshore Wind Zone O&M Base, I describe how the Port of Great Yarmouth had been selected as the O & M base.
  4. Great Yarmouth and nearby Lowestoft are both ports, with a long history of supporting shipbuilding and offshore engineering.

The wind farms and the operational port are all close together, which probably makes things convenient.

So why did Vattenfall sell the development rights of the three wind farms to RWE?

Too Much Wind?

East Anglia is fringed with wind farms all the way between the Wash and the Thames Estuary.

  • Lincs – 270 MW
  • Lynn and Inner Dowsing – 194 MW
  • Race Bank – 580 MW
  • Triton Knoll – 857 MW
  • Sheringham Shoal – 317 MW
  • Dudgeon – 402 MW
  • Hornsea 3 – 2852 MW *
  • Scroby Sands – 60 MW
  • East Anglia One North – 800 MW *
  • East Anglia Two – 900 MW *
  • East Anglia Three – 1372 MW *
  • Greater Gabbard – 504 MW
  • Galloper – 353 MW
  • Five Estuaries – 353 MW *
  • North Falls – 504 MW *
  • Gunfleet Sands – 172 MW
  • London Array – 630 MW

Note.

  1. Wind farms marked with an * are under development or under construction.
  2. There is 4339 MW of operational wind farms between the Wash and the Thames Estuary.
  3. An extra 6781 MW is also under development.

If all goes well, East Anglia will have over 11 GW of operational wind farms or over 15 GW, if the three Norfolk wind farms are built.

East Anglia is noted more for its agriculture and not for its heavy industries consuming large amounts of electricity, so did Vattenfall decide, that there would be difficulties selling the electricity?

East Anglia’s Nimbies

East Anglia’s Nimbies seem to have started a campaign against new overground cables and all these new wind farms will need a large capacity increase between the main substations of the National Grid and the coast.

So did the extra costs of burying the cable make Vattenfall think twice about developing these wind farms?

East Anglia and Kent’s Interconnectors

East Anglia and Kent already has several interconnectors to Europe

  • Viking Link – Bicker Fen and Jutland – 1.4 GW
  • LionLink – Suffolk and the Netherlands – 1.8 GW – In Planning
  • Nautilus – Suffolk or Isle of Grain and Belgium – 1.4 GW – In Planning
  • BritNed – Isle of Grain and Maasvlakte – 1.0 GW
  • NeuConnect – Isle of Grain and Wilhelmshaven – 1.4 GW – Under Construction
  • GridLink Interconnector – Kingsnorth and Warande – 1.4 GW – Proposed
  • HVDC Cross-Channel – Sellinge and Bonningues-lès-Calais – 2.0 GW
  • ElecLink – Folkestone and Peuplingues – 1.0 GW
  • Nemo Link – Richborough and Zeebrugge – 1.0 GW

Note.

  1. Five interconnectors with a capacity of 6.4 GW.
  2. A further four interconnectors with a capacity of 6 GW are on their way.

At 12.4 GW, the future capacity of the interconnectors between South-East England and Europe, is nor far short of South-East English wind power.

There are also two gas pipelines from the Bacton gas terminal between Cromer and Great Yarmouth to Europe.

The Wikipedia entry for the Bacton gas terminal gives these descriptions of the two gas pipelines.

Interconnector UK – This can import gas from, or export gas to, Zeebrugge, Belgium via a 235 km pipeline operating at up to 147 bar. There is a 30-inch direct access line from the SEAL pipeline. The Interconnector was commissioned in 1998.

BBL (Bacton–Balgzand line) – This receives gas from the compressor station in Anna Paulowna in the Netherlands. The BBL Pipeline is 235 km long and was commissioned in December 2006.

It would appear that East Anglia and Kent are well connected to the Benelux countries, with both electricity and gas links, but with the exception of the Viking Link, there is no connection to the Scandinavian countries.

Did this lack of connection to Sweden make convincing the Swedish government, reluctant to support Vattenfall in their plans?

Bringing The Energy From The Norfolk Wind Farms To Market

It looks to me, that distributing up to 4.2 GW from the Norfolk wind farms will not be a simple exercise.

  • Other wind farms like the 2852 MW Hornsea 3 wind farm, may need a grid connection on the North Norfolk coast.
  • The Nimbies will not like a South-Western route to the National Grid at the West of Norwich.
  • An interconnector to Denmark or Germany from North Norfolk would probably help.

But at least there are two gas pipelines to Belgium and the Netherlands.

RWE, who now own the rights to the Norfolk wind farms, have a large amount of interests in the UK.

  • RWE are the largest power producer in the UK.
  • They supply 15 % of UK electricity.
  • They have interest in twelve offshore wind farms in the UK. When fully-developed, they will have a capacity of almost 12 GW.
  • RWE are developing the Pembroke Net Zero Centre, which includes a hydrogen electrolyser.

RWE expects to invest up to £15 billion in the UK by 2030 in new and existing green technologies and infrastructure as part of this.

Could this be RWE’s plan?

As the Norfolk wind farms are badly placed to provide electricity to the UK grid could RWE have decided to use the three Norfolk wind farms to produce hydrogen instead.

  • The electrolyser could be placed onshore or offshore.
  • If placed onshore, it could be placed near to the Bacton gas terminal.
  • There are even depleted gas fields, where hydrogen could be stored.

How will the hydrogen be distributed and/or used?

It could be delivered by tanker ship or tanker truck to anyone who needs it.

In Developing A Rural Hydrogen Network, I describe how a rural hydrogen network could be developed, that decarbonises the countryside.

There are three major gas pipelines leading away from the Bacton gas terminal.

  1. The connection to the UK gas network.
  2. Interconnector UK to Belgium.
  3. BBL to The Netherlands.

These pipelines could be used to distribute hydrogen as a hydrogen blend with natural gas.

In UK – Hydrogen To Be Added To Britain’s Gas Supply By 2025, I describe the effects of adding hydrogen to the UK’s natural gas network.

Europe’s Mines Look To Gravity Energy Storage For Green Future

The title of this post, is the same as that of this article on Global Mining Review.

This is the sub-heading.

Mine owners across Europe are looking at a new form of underground energy storage to offer a low carbon future as operations wind down.

These are the first four paragraphs.

Active deep mine operators in Slovenia, Germany, The Czech Republic and Finland are all examining how underground gravity energy storage – provided by Edinburgh firm Gravitricity – could offer green opportunities to mining communities facing a downturn in employment.

Gravitricity has developed a unique energy storage system, known as GraviStore, which uses heavy weights – totalling up to 12 000 t – suspended in a deep shaft by cables attached to winches.

This offers a viable alternative future to end of life mine shafts, which otherwise face costly infilling and mine decommissioning costs.

They have teamed up with energy multinational and winch specialist ABB alongside worldwide lifting specialists Huisman to commercialise the technology for mine operators.

Note.

  1. Four projects are mentioned.
  2. It appears to be less costly, than infilling.
  3. Gravitricity have teamed with ABB and Huisman, who are two of Europe’s specialist in this field.
  4. You can’t have too much energy storage.

The article is worth a full read.

Conclusion

Gravitricity’s simple idea could be a big winner.

Wrightbus Secures Further German Order For 46 Hydrogen Buses

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

These paragraphs outline the deal.

World-beating zero-emission bus manufacturer Wrightbus today announced a milestone deal to provide 46 hydrogen buses to Germany – taking a demo bus from Belfast to showcase its reliability and range.

 

The buses ordered by Cottbusverkehr GmbH will serve the city of Cottbus, the second largest city in the state of Brandenburg, and and in the western part of the district of Spree-Neiße.

 

It follows a landmark announcement by the German government to implement a €350 million scheme to support the production of renewable hydrogen.

 

Wrightbus is Europe’s fastest-growing bus manufacturer and follows the company’s rapid rise since it was bought out of administration in 2019. It was named Northern Ireland’s fastest-growing company by Growth Index this week – employing 1,650 people and producing 22 buses a week.

 

The Cottbus order for the Kite Hydroliner buses follow deals in Germany with West Verkehr, Regionalverkehr Köln GmbH (RVK), and Saarbahn GmbH, with more European orders in the pipeline.

If Northern Irish hydrogen buses are selling well to the Germans, why are there so few in the UK.

These pictures show the UK version of the German buses in Crawley.

They are excellent buses.

Denmark Launches Massive Offshore Wind Auction

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

This is the sub-heading.

Denmark has opened a new offshore wind tender, the country’s largest ever, offering a minimum of 6 GW of new capacity spread over six wind farms, with the overplanting option allowing for 10 GW or more of new capacity to be added.

These are two paragraphs from the article.

The offshore wind farms must deliver at least 6 GW, and as a new element, there will be freedom to establish as much offshore wind as possible on the tendered areas, with the exemption of Hesselø with a maximum capacity of 1.2 GW.

If the market utilizes this freedom to optimize the usage of the areas, it could result in the construction of 10 GW offshore wind or more, the agency said.

Recently, some wind farms in the UK have been increased in size after the auction.

In Crown Estate Mulls Adding 4 GW Of Capacity From Existing Offshore Wind Projects, I note how 4 GW of overplanting could be employed to raise the total capacity from 4.6 GW to 8.6 GW.

So have the Danes decided to build expansion into the tender?

One of the wind farms in the auction is called Nordsøen I.

  1. It will be about 50 km. from the West Coast of Denmark.
  2. It appears it will have a capacity of at least 1 GW.
  3. It could connect to the shore, not far from where the Viking Link between Lincolnshire and Denmark connects to the Danish grid.
  4. There is a 700 MW interconnector between the area and Eemshaven in The Netherlands.
  5. There is 1.5 GW of overland transmission lines to Germany.

All these connections, increase energy security for Denmark, Germany, the Netherlands and the UK.

Could the Danes be building the Nordsøen I, so it could work with the all the connections in Southern Jutland and improve energy security?

Canadian Pension Fund To Consolidate Its Offshore Wind Holdings Into UK-Based Reventus Power

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

This is the sub-heading.

Canada Pension Plan Investment Board (CPP Investments) will consolidate its existing direct and indirect offshore wind holdings into Reventus Power, its UK-based portfolio company, which will become its dedicated global offshore wind platform.

This first paragraph gives more details.

Subject to customary approvals, the move will see Reventus Power growing its teams in the UK, Germany, Poland and Portugal to form a team of approximately 50 offshore wind specialists, according to CPP Investments, whose current exposure to offshore wind is more than CAD 1 billion (approximately EUR 678 million; USD 737 million).

According to their web site, the Reventus HQ is in London.

There is nothing on the web to indicate a special reason, so it must have been one of the following.

  • Canadians like investing in the UK.
  • The UK is good for tax reasons.
  • London has all the lawyers, accountants and other services they will need.
  • I suspect several wind farms, that they will develop will be in UK waters.
  • Many of the extra staff, they have said they will recruit will be UK-based or UK-educated.

But overall, it must be a feather in its cap for London.

How Germany Is Dominating Hydrogen Market

The title of this post, is the same as that of this article on Hydrogen Fuel News.

This is the sub heading.

With 3827 kilometers of pipeline across the country, Germany is blazing a trail through the continent in terms of hydrogen infrastructure growth.

These are the first two paragraphs.

Indeed, plans within the country are so far advanced that Germany is set to become the biggest importer of hydrogen in Europe and the third biggest in the world, behind global leaders China and Japan.

All this leaves the German transport sector in good stead, with a strong infrastructure supporting clean fuel adoption, while the country transitions towards net zero.

So where are the Germans going to get their hydrogen from?

One possibility is the UK.

  • The UK has vast amounts of renewable energy.
  • We’re only hundreds of kilometres, instead of thousands of kilometres away.
  • RWE; the German energy giant has full or partial interests in about 12,3 GW of UK wind farms.
  • RWE is building the Pembroke Net Zero Centre which will generate green and blue hydrogen.

Hydrogen could be exported from the UK to Germany by tanker.

Conclusion

Production and exporting of green hydrogen will become significant industry in the UK.

UK ESO Unveils GBP 58 Billion Grid Investment Plan To Reach 86 GW of Offshore Wind By 2035

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

This is the sub-heading.

Great Britain’s electricity system operator (ESO) has proposed a GBP 58 billion (approximately EUR 68 billion) investment in the electricity grid. The proposal outlines a vision for incorporating an additional 21 GW of offshore wind into the grid by 2035, which would bring the country’s total offshore wind capacity to a potential 86 GW.

These three paragraphs add more details to what the investment in the grid means for offshore wind.

The ESO released on 19 March the first Beyond 2030 report. The plan sets up the necessary infrastructure to transfer power to and from future industries, as electricity demand is expected to rise by 64 per cent by 2035, according to the ESO.

The grid operator said that the plan connects a further 21 GW of offshore wind in development off the coast of Scotland to the grid in an efficient and coordinated way which would bring the country’s total offshore wind capacity to a potential 86 GW.

The proposals could assist the UK government in meeting the sixth Carbon Budget and allow for the connection of Crown Estate Scotland’s ScotWind leasing round.

These are my thoughts.

How Much Offshore Wind Is In The Pipeline?

This Wikipedia entry is a List Of Offshore Wind Farms In The United Kingdom.

It gives these figures for wind farms in various operational an development states.

  • Operational – 14,703 MW
  • Under Construction – 5,202 MW
  • Pre-Construction – 6,522 MW
  • Contracts for Difference – Round 3 – 12 MW
  • Contracts for Difference – Round 4 – 1,428 MW
  • Early Planning – England – 18,423 MW
  • Early Planning – Wales – 700 MW
  • Early Planning – Scotland – 30,326 MW

Note.

  1. These add up to a total of 77,316 MW.
  2. If all the wind farms in the Wikipedia entry are commissioned, the UK will be short of the 86,000 MW total by 8,664 MW.
  3. Some wind farms like Ossian could be increased in size by a few GW, as I reported in Ossian Floating Wind Farm Could Have Capacity Of 3.6 GW.

It looks like only another 7,164 MW of offshore wind needs to be proposed to meet the required total.

This article on offshoreWIND.biz is entitled The Crown Estate Opens 4.5 GW Celtic Sea Floating Wind Seabed Leasing Round, will add another 4,500 MW to the total, which will raise the total to 81,816 MW.

The article also finishes with this paragraph.

Round 5 is expected to be the first phase of development in the Celtic Sea. In November 2023, the UK Government confirmed its intention to unlock space for up to a further 12 GW of capacity in the Celtic Sea.

A further 12 GW of capacity will take the total to 93,816 MW.

In Three Shetland ScotWind Projects Announced, I talked about three extra Scotwind wind farms, that were to be developed to the East of Shetland.

These will add 2.8 GW, bringing the total to 96,616 MW.

I don’t think the UK has a problem with installing 86 GW of offshore wind by 2035, so we must create the electricity network to support it.

The Electricity Network In 2024

I clipped this map from this article in The Telegraph, which is entitled Britain’s Energy System Will Not Hit Net Zero Until 2035, National Grid Tells Labour.

 

The dark blue lines are the 400 kV transmission lines.

  • The one furthest East in East Anglia serves the Sizewell site, which hosts the Sizewell B nuclear power station and will be the home of Sizewell C nuclear power station, unless the Green or LibDem Parties are a member of a coalition government.
  • Kent and Sussex seem to be encircled by 400 kV lines, with small spurs to the interconnectors to Europe.
  • Two 400 kV lines appear to serve the South-West peninsular, with one going along the South Coast and the other further North. I suspect these two motorways for electricity explain, why the Morocco-UK Power Project terminates in Devon.
  • London seems to have its own M25 for electricity.
  • There also appears to be an East-West link to the North of London linking Sizewell in the East and Pembroke in the West. Both ends have large power stations.
  • There also appear to be two 400 kV lines from Keadby by the Humber Estuary to North Wales with the pumped storage hydro power station at Dinorwig.
  • Two more 400 kV lines link Yorkshire to the South of Scotland.
  • A lonely Northern cable connects Edinburgh and the North of Scotland.

The red lines, like the one encircling central London are the 275 kV transmission lines.

  • Think of these as the A roads of the electricity network.
  • They encircle London often deep underground or under canal towpaths.
  • They reinforce the electricity network in South Wales.
  • Liverpool appears to have its own local network.
  • They also seem to provide most of the capacity North of and between Edinburgh and Glasgow.

Newer cables are starting to appear on this map.

There are two light blue cables and these are HVDC cables that run underwater.

  • The 1.2 GW Caithness – Moray Link does what it says in the name and it connects the far North of Scotland direct towards Aberdeen.
  • The much larger 2.25 GW Western HVDC Link connects Hunterston near Glasgow to Flintshire Bridge near Liverpool. Note how it passes to the West of the Isle of Man.

Not shown on the map are the smaller 500 MW Moyle Interconnector and the recently-opened 600 MW Shetland HVDC Connection.

The Electricity Network In 2050

This second map shows how the network will look in 2050.

Note.

  1. The colours are the same, as the previous map.
  2. Although, I do think there are some errors in which have been used.
  3. There are a lot more cables.

There are several more light blue cables and these are HVDC cables that run underwater.

  • Shetland is now linked to the North of Scotland by the Shetland HVDC Connection.
  • There appears to be a cluster of HVDC interconnectors at Caithness HVDC switching station, near Wick, including a new one to Orkney, to go with the others to Moray and Shetland.
  • The 2 GW Scotland England Green Link 1 will run from Torness in Southeast Scotland to Hawthorn Pit substation in Northeast England.
  • The 2 GW Eastern Green Link 2 will run from Sandford Bay, at Peterhead in Scotland, to the Drax Power Station in Yorkshire, England.
  • There also appear to be two or possibly three other offshore cables linking the East Coast of Scotland with the East Coast of England.
  • If the Eastern cables are all 2 GW, that means there is a trunk route for at least 8 GW between Scotland’s wind farms in the North-East and Eastern England, which has the high capacity wind farms of Dogger Bank, Hornsea and around the Lincolnshire and East Angliam coasts.
  • Turning to the Western side of Scotland, there appears to be a HVDC connection between the Scottish mainland and the Outer Hebrides.
  • South-West of Glasgow, the Western HVDC Link appears to have been duplicated, with a second branch connecting Anglesey and North-West Wales to Scotland.
  • The Moyle Interconnector must be in there somewhere.
  • Finally, in the South a link is shown between Sizewell and Kent. It’s shown as 400 kV link but surely it would be a HVDC underwater cable.

There are also seven stubs reaching out into the sea, which are probably the power cables to the wind farms.

  • The red one leading from South Wales could connect the wind farms of the Celtic Sea.
  • The blue link North of Northern Ireland could link the MachairWind wind farm to the grid.
  • The other two red links on the West Coast of Scotland could link to other ScotWind wind farms.
  • The red link to the North of East Anglia could link RWE’s Norfolk wind farms to the grid.
  • The other stubs in the East could either connect wind farms to the grid or be multi-purpose interconnectors linking to Germany and the Netherlands.

It looks to me, that National Grid ESO will be taking tight control of the grid and the connected wind farms, as an integrated entity.

As a Graduate Control Engineer, I can’t disagree with that philosophy.

Hydrogen Production

In How Germany Is Dominating Hydrogen Market, I talked about how Germany’s plans to use a lot of hydrogen, will create a large world-wide demand, that the UK because of geography and large amounts of renewable energy is in an ideal place to fulfil.

I can see several large electrolysers being built around the UK coastline and I would expect that National Grid ESO have made provision to ensure that the electrolysers have enough electricity.

Would I Do Anything Different?

Consider.

  • If it is built the Morocco-UK Power Project will terminates in Devon.
  • There could be more wind farms in the Celtic Sea.
  • It is likely, that the wind farms in the Celtic Sea will connect to both Pembroke and Devon.
  • Kent has interconnectors to the Continent.

Would a Southern HVDC link along the South Coast between Devon and Kent be a good idea?

Conclusion

Looking at the proposed list of wind farms, a total in excess of 96 GW could be possible, which is ten GW more than needed.

The network not only serves the UK in a comprehensive manner, but also tees up electricity for export to Europe.

UK Energy Grid Needs £60bn Upgrade To Hit Green Target, Plan Says

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

This is the sub-heading.

The UK’s electricity network needs almost a further £60bn of upgrades to hit government decarbonisation targets by 2035, according to a new plan.

These five paragraphs explain the plan.

About 4,000 miles of undersea cables and 1,000 miles of onshore power lines are needed, said the National Grid’s Electricity Systems Operator (ESO).

The investment would add between £20 to £30 a year to customer bills, it said.

The government said the ESO’s plans were preliminary and yet to pass a “robust planning process”.

The plans were written up by the ESO, the organisation which runs the electricity network and would run the updated system it is calling for too. It is currently owned by National Grid but will transfer into government ownership later this year.

Its latest £58bn estimate is for work needed between 2030 and 2035 and comes on top of a previous £54bn estimate for work taking place between now and 2030.

These are my thoughts.

The Amount Of Undersea Cable

Edinburgh and London are roughly 400 miles apart as the train runs, so it looks like there could be the equivalent of ten underwater cables between the North of Scotland and England.

In Contracts Signed For Eastern Green Link 2 Cable And Converter Stations, I talked about the proposed 2 GW link between Peterhead in Scotland and Drax in England, which will be a double cable. So there’s the first two of these long cables.

It looks to me, that National Grid are proposing to use underwater cables wherever they can, so they avoid large expensive planning rows stirred up by Nimbies.

Monitoring The Undersea Cables

Last week Ofgem gave National Grid a £400,000 grant to develop new innovative technologies, which I wrote about in £400k For National Grid Innovation Projects As Part Of Ofgem Fund To Help Shape Britain’s Net Zero Transition.

One of the project is called HIRE – Hybrid-Network Improvement & Reliability Enhancement and will be used to check all these cables are performing as they should.

My electrical engineering experience tells me, that there must be some cunning way, that will detect that something is happening to the cable. The involvement of a technology company called Monitra in the project is a bit of a giveaway.

How Much Will It Cost Me?

Currently, UK consumers pay about £30 per year to have electricity delivered, so this will rise to between £50 and £60 per year.

That is just over a pound a week. I would pay about the same for a resident’s parking permit outside my house for an electric car and probably three times more for a petrol or diesel car.

Do We Have Enough Cable?

Two undersea cable factories are under development in Scotland and I suspect the 4,000 miles of undersea cables will be delivered on schedule and covered in saltires.

What About T-Pylons?

The latest onshore electricity transmission line between Hinckley Point C and Bristol, doesn’t use traditional pylons.

It uses T-pylons like these to connect the 3.26 GW nuclear power station.

Note that they are shorter, designed to be less intrusive, have a smaller footprint and are made from only ten parts.

I suspect they will cost less to install and maintain.

There is more on T-pylons in National Grid Energise World’s First T-Pylons.

I wouldn’t be surprised that some of the oldest traditional pylons will be replaced by T-pylons.

I am surprised that T-pylons are not mentioned in the BBC article.

I like T-pylons. How do you feel about them?

Eastern Green Link 2

This press release from National Grid, describes Eastern Green Link 2 like this.

Eastern Green Link 2 (EGL2) is a 525kV, 2GW high voltage direct current (HVDC) subsea transmission cable from Peterhead in Scotland to Drax in England delivered as a joint venture by National Grid and SSEN Transmission.

This map from National Grid, shows the route of the Eastern Green Link 2.

The Northern landfall is at Sandford Bay and the Southern landfall is at Wilsthorpe Beach.

This Google Map shows Sandford Bay and Peterhead power station.

Note.

  1. Sandford Bay occupies the North-East corner of the map.
  2. The red arrow indicates the main 400kV sub-station at Peterhead.
  3. The 2177 MW gas-fired Peterhead power station is to the East of the sub-station marked as SSE.

This second Google Map shows the onshore route of the cable from Wilsthorpe to Drax.

Note.

  1. Flamborough Head is in the North-East corner of the map.
  2. Wilsthorpe Beach is at Bridlington a couple of miles South of Flamborough Head.
  3. The red arrow indicates Drax Power station.
  4. An onshore underground cable will be installed from landfall in Wilsthorpe to a new onshore converter station built in Drax.

The EGL2 HVDC cable connection from Scotland to England consists of 436km of submarine cable and 69km of onshore cable.

Both converter stations will be on existing power station sites and the major onshore works will be the underground cable between Wilsthorpe and Drax.

Where Does Drax Go From Here?

Currently, Drax power station is a 2595 MW biomass-fired power station.

There are now other large power sources that could replace some or all of the output of Drax power station.

  • 2GW of Scottish wind power coming to Drax on Eastern Green Link 2.
  • 6 GW of offshore wind is being developed at the Hornsea wind farms.
  • 8 GW of offshore wind is being developed at the Dogger Bank wind farms.
  • 2.5 GW from the three gas-fired power stations at Keadby, two of which are likely to be fitted with carbon capture.
  • 1.8 GW from the proposed hydrogen-fired Keadby Hydrogen power station.

Given the bad feelings many have about Drax burning biomass, with 20.3 GW of electricity, you might think that shutting down Drax would be a simple solution.

But, according to Drax’s Wikipedia entry, it has a unique property.

Despite this intent for baseload operation, it was designed with a reasonable ability for load-following, being able to ramp up or down by 5% of full power per minute within the range of 50–100% of full power.

So Drax could be very useful in balancing the grid, by ramping up and down to fill the gap between production and need.

In addition, there is good biomass. This is from the Wikipedia entry.

A 100,000 tonne pa capacity straw pelletization facility was constructed at Capitol Park, Goole in 2008.

Drax are also promoting BECCS or Bioenergy carbon-capture and storage.

There is a Wikipedia entry for Bioenergy With Carbon Capture And Storage, of which this is the first couple of sentences.

Bioenergy with carbon capture and storage (BECCS) is the process of extracting bioenergy from biomass and capturing and storing the carbon, thereby removing it from the atmosphere. BECCS can theoretically be a “negative emissions technology” (NET).

I do feel that carbon capture and storage is a bit like sweeping the dust under the carpet, when you sweep the floor around it.

But carbon capture and use could be another matter.

This Google Map shows the Drax site.

Note how it is surrounded by agricultural land.

Could the power station be the source of pure carbon dioxide to be fed in greenhouses to flowers, herbs, salad vegetables, tomatoes and other plants?

I suspect there’s productive life left in Drax power station yet!

LionLink

LionLink, that is being developed by National Grid is a new type of interconnector, called a multi-purpose interconnector, that will connect Suffolk and The Netherlands via any convenient wind farms on the way. This means that the electricity generated can go where it is needed most.

I wrote about LionLink in World’s Largest-Of-Its-Kind Power Line To Deliver Clean Power To 1.8m UK Homes And Boost Energy Security.

Other Multi-Purpose Interconnectors

I can see other multi-purpose interconnectors like LionLink being built around the UK.

  • There could be one across the Dogger Bank to link out 8 GW of Dogger Bank wind farms with those of the Dutch, Danes and Germans on their section of the bank.
  • NorthConnect could be built between Scotland and Norway via some of the wind farms being developed to the North-East of Scotland.
  • Could wind farms to the North of Ireland use a multi-purpose interconnector between Scotland and Northern Ireland.
  • I can also see one or possibly two, being built across the Celtic Sea to link Devon, South Wales and Southern Ireland via the wind farms being developed in the area.
  • Will we also see a Channel multi-purpose interconnector to transfer electricity along the South Coast of England?

Some of these multi-purpose interconnectors could be key to creating a revenue stream, by exporting electricity, to countries in Europe, that have a pressing need for it.

Conclusion

National Grid’s excellent plan will lead to the end of the practice of shutting down wind turbines. The spare electricity will be exported to Europe, which will surely create a good cash-flow for the UK. This in turn will encourage developers to create more wind farms in the seas around the UK’s coasts.

Dogger Bank D Welcomes Confirmation Of Grid Connection Location

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

This is the sub-heading.

Project team now focusing full attention on electrical transmission system connection.

These four paragraphs describe the proposed connection to the National Grid.

SSE Renewables and Equinor have welcomed confirmation of a grid connection location from the Electricity System Operator (ESO) for a proposed fourth phase of the world’s largest offshore wind farm.

Dogger Bank D will now connect into Birkhill Wood, a proposed new 400kV substation located in the East Riding of Yorkshire which will be built as part of National Grid’s Great Grid Upgrade.

The announcement follows the publication of an impact assessment for the South Cluster by ESO, relating to energy projects which are due to be electrically connected off the east coast of England.

With the location of a grid connection confirmed, Dogger Bank D will now focus its full attention on connecting to the electrical transmission system.

This is a big change from December 2023, when I wrote Plans for Hydrogen Development At Dogger Bank D Gain Ground, which indicated that Dogger Bank D would be used to produce hydrogen, so the grid connection wouldn’t be needed.

Using A Offshore Hybrid Asset Between the UK And Another European Country

This is the next paragraph on the SSE Renewables press release.

The project is also exploring the future possibility of the development of Dogger Bank D to be coordinated with an Offshore Hybrid Asset between the UK and another European country’s electricity market to form a multi-purpose interconnector. This option would increase energy security for the UK and reduce the need to curtail offshore wind output in times of oversupply on the GB network.

Note that just over the boundary of the UK’s Exclusive Economic Zone are the Dutch and German Exclusive Economic Zones.

It is not unreasonable to believe that UK, Dutch and German grid could all be connected on the Dogger Bank.

Connecting Everything Up At Birkhill Wood

This is the next paragraph on the SSE Renewables press release.

The project team are undertaking a site selection process to identify potential cable corridors and where other onshore infrastructure associated with the grid connection at Birkhill Wood may be sited. Consultation will be held later this year to introduce the connection proposals to the local community.

At least now, with the connection to Birkhill Wood confirmed, SSE and Equinor will be able to supply any electricity generated at Dogger Bank D to the UK grid, up to limit of the connection.

The Value Of Electricity That Could Be Generated At Dogger Bank D

Consider.

  • The wind farm has a capacity of 2 GW or 2,000 MW.
  • There are 365 days in most years.
  • There are 24 hours in the day.
  • This means that 17, 520,000 MWh could be generated in a year.
  • A large wind farm like Hornsea One has a twelve month rolling capacity factor of 46.6%.
  • Applying this capacity factor says that 8,164,320 MWh will be generated in a year.
  • The Contract for Difference Round 6 for this electricity will be £73/MWh.

Applying that figure gives a yearly turnover of £ 595,995,360 or £ 297,997,680 per installed GW.

It is not unreasonable to assume that half of this electricity were to be exported to power Germany industry.

It could be a nice little earner for the Treasury.

Ørsted Secures Exclusive Access To Lower-Emission Steel From Dillinger

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

This is the sub-heading.

Ørsted will be offered the first production of lower-emission steel from German-based Dillinger, subject to availability and commercial terms and conditions. The steel plates are intended to be used for offshore wind monopile foundations in future projects.

These three paragraphs outline the deal.

Under a large-scale supply agreement entered into in 2022, Ørsted will procure significant volumes of regular heavy plate steel from 2024, giving the company access at scale to and visibility of the most crucial raw material in offshore wind while supporting Dillinger to accelerate investments in new lower-emission steel production, according to Ørsted.

The Danish renewable energy giant expects to be able to procure lower-emission steel produced at Dillinger’s facility in Dillingen, Germany, from 2027-2028.

Taking the current technology outlook into account, the reduction of the process-related carbon emissions from production is expected to be around 55-60 per cent compared to conventional heavy plate steel production, Ørsted said.

Increasingly, we’ll see lower emission steel and concrete used for wind turbine foundations.

This press release on the Dillinger web site is entitled Historic Investment For Greater Climate Protection: Supervisory Boards Approve Investment Of EUR 3.5 billion For Green Steel From Saarland.

These are two paragraphs from the press release.

Over the next few years leading up to 2027, in addition to the established blast furnace route, the new production line with an electric arc furnace (EAF) will be built at the Völklingen site and an EAF and direct reduced iron (DRI) plant for the production of sponge iron will be built at the Dillinger plant site. Transformation branding has also been developed to visually represent the transformation: “Pure Steel+”. The message of “Pure Steel+” is that Saarland’s steel industry will retain its long-established global product quality, ability to innovate, and culture, even in the transformation. The “+” refers to the carbon-neutrality of the products.

The availability of green hydrogen at competitive prices is a basic precondition for this ambitious project to succeed, along with prompt funding commitments from Berlin and Brussels. Local production of hydrogen will therefore be established as a first step together with the local energy suppliers, before connecting to the European hydrogen network to enable use of hydrogen to be increased to approx. 80 percent. The Saarland steel industry is thus laying the foundation for a new hydrogen-based value chain in the Saarland, in addition to decarbonizing its own production. In this way, SHS – Stahl-Holding-Saar is supporting Saarland on its path to becoming a model region for transformation.

It sounds to me, that Tata Steel could be doing something similar at Port Talbot.

  • Tata want to build an electric arc furnace to replace the blast furnaces.
  • There will be plenty of green electricity from the Celtic Sea.
  • RWE are planning a very large hydrogen electrolyser in Pembroke.
  • Celtic Sea offshore wind developments would probably like a supply of lower emission steel on their door-step.

I would suspect, that Welsh steel produced by an electric arc furnace will match the quality of the German steel, that is made the same way.
