What Caused The Amazon Web Services Failure?
This article on Reuters is entitled Amazon’s AWS Struggles To Recover After Major Outage Disrupts Apps, Services Worldwide, sums up today’s big news story.
But what went wrong?
I asked Google AI, where BT have their data servers and received this reply.
BT hosts its data servers in various locations across the UK, including London, Birmingham, and Dublin, Ireland, as well as in mainland Europe such as Frankfurt, Germany, and Amsterdam and Nieuwegein, Netherlands. They also have a presence in the United States, with facilities in locations like New Jersey.
Note.
- Nieuwegein is South of Amsterdam.
- There’s almost a direct straight-line route between Dublin and Frantfurt.
- Cambridge would lie on that straight-line route.
- BT’s Research at Martlesham in Suffolk would lie on that straight-line route.
- Is BT’s worldwide network closely monitored from BT Research?
- For more about BT Research read their Wikipedia entry.
- The straight-line route by-passes London.
The network seems comprehensive and well spread-out.
These are my thoughts.
The Value Of Research
I asked Google AI, if there were any spin-out companies from BT Martlesham and received this reply.
Yes, spin-out companies have been formed from BT’s Adastral Park research facility, including Real Time Content (RTC) and iome. Both companies were supported by BT and developed technologies based on research from the Martlesham site, with RTC focusing on personalized video services and iome providing location-based services through mobile internet.
I used to live near to BT’s Research Centre until 1990.
At the time, I was writing Artemis, the project management system and the multi-user version of that software and a BT research computer system used the same Hewlett-Packard hardware and an operating system written by BT at Martlesham.
Because of this connection, I learned a lot about their methods and the breadth of the research being carried out in Suffolk and was generally impressed.
I would suspect that legacy telecom companies like BT, France Telecom and Deutsche Telecom spend a lot of money on research. Do newer companies spend similar amounts?
Having a good research department behind you is an excellent form of insurance!
Will BT Research Have A Reliable 24/7 Power Supply?
Consider.
- By 2030, there will be upwards of 4 GW of offshore wind power along the Suffolk coast.
- Sizewell B will be 22 miles away, pumping out 1.2 GW until at least 2035.
- Sizewell C could be pumping out 3.3 GW from the mid-2030s.
- The 1.8 GW LionLink between Walberswick in Suffolk and The Netherlands could be in operation by 2030.
I am fairly sure that BT Research will have enough power, even if several data centres are built on the Martlesham site.
The Domain Name Res0lution Problem
Consider.
- The root causeof Amazon’s disaster appeared to be problems with its domain name resolution system.
- Executing fast lookup of domain names is critical.
I had a similar problem with the project management system ; Artemis, when I extended it to be one of the first relational databases in the 1980s. So I went to IBM’s library on the South Bank and dug out all their 1950s papers on looking up keys in tables.
In those days, with slower computers, which had smaller amounts of memory, the efficiency of the algorithm was very important and I got a significant improvement in look-up speed, by digging up ideas from the past.
If anybody wants to check out their algorithm with me, I’m always happy to oblige, but at 78 with poor eye-sight I’m probably past coding anything myself.
When I was dealing with BT Research, they would have made sure that something like domain name resolution was given the full research treatment.
My Conclusion
As I don’t have all the data, I will not speculate, but will await Amazon’s conclusion with interest.
Saxmundham Station – 14th March 2025
On Friday, I went to Saxmundham to view the presentation of LionLink.
I took these pictures of Saxmundham station.
Note.
- The trains are two of Greater Anglia’s excellent Class 755 trains.
- The line is double track at Saxmundham station.
- The station building suffered a devastating fire 2018 and has since been rebuilt.
- Access between train and platform is step-free. See the gap fillers in the first two pictures.
- The tracks are crossed by the use of the level-crossing.
- There was a new comfortable and warm waiting room.
- There is a small car park.
- There is an hourly train in both directions to Ipswich and Lowestoft.
The station is in walking distance from the town.
These are my thoughts.
Extra Services
This OpenRailwayMap shows Saxmundham station and the Aldeburgh branch, which also serves the Sizewell power stations.
Note.
- The blue arrow indicates Saxmundham station.
- The yellow track is the East Suffolk Line.
- A disused branch line curves East, to the North of Saxmundham station and then South to the former site of Aldeburgh station.
- Sidings for Sizewell C construction trains will be built along this branch line.
Would it not be a good idea to reinstate the railway to Aldeburgh and run a second hourly train between Aldeburgh and Ipswich?
- There is space for a Platform 0 at Ipswich station.
- There is only the hourly Ipswich and Lowestoft train in both directions on the East Suffolk Line.
- Simple one platform stations would be needed at Leiston, Sizewell, Thorpness and Aldeburgh.
- There is probably enough double track for the extra train.
The current Ipswich and Saxmundham service takes about 34 minutes, so I suspect two trains would be needed for an Ipswich and Aldeburgh shuttle.
In the Wikipedia entry for Aldeburgh station, there is this paragraph.
In 1929 the LNER introduced luxurious Pullman day excursion trips from Liverpool Street to various seaside resorts. The service, known as the Eastern Belle, served Felixstowe on Mondays, Frinton and Walton on Tuesdays, Clacton on Wednesdays and Thorpeness and Aldeburgh on Thursdays and Fridays. The service ended in September 1939 when the Second World War broke out.
Perhaps not a Pullman service, but a kids special in the summer holidays.
Could Bealings Station Be Rebuilt?
Bealings station, which used to be between Westerfield and Woodbridge stations was closed in 1956.
This Google Map shows its location.
The station is now the Mallard House Business Centre.
UK, Netherlands To Connect Grids via Nederwiek 3 Offshore Wind Farm
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Dutch Climate and Green Growth Minister Sophie Hermans has included LionLink, said to be the first direct-current hybrid interconnector, in the country’s latest Offshore Wind Energy Development Framework. LionLink will use the offshore grid connection of Nederwiek 3 offshore wind farm in the Netherlands to connect to both the Dutch and the UK onshore high-voltage grids.
These are points from the article.
- The interconnector can also be used as an additional high-voltage link to exchange electricity between the countries.
- With LionLink now added to the offshore wind development framework, TenneT may now make investments in the project, which the Dutch transmission system operator (TSO) is realising in close cooperation with UK partner National Grid Ventures (NGV).
- Nederwiek 3 is planned to be launched in 2026.
The offshore grid between the UK and Europe is on its way.
What Are Offshore Hybrid Assets?
The title of this post is the same as that of a story explaining energy from National Grid.
This is the sub-heading.
Offshore Hybrid Assets or OHAs (formerly known as multi-purpose interconnectors) are a new generation of subsea technology that will connect clusters of offshore wind farms to multiple countries.
This is the first paragraph.
OHAs will help to speed up the connection of offshore wind and maximise the use of wind generation. They will also reduce the impact on local communities by reducing the amount of connection points and onshore infrastructure required to connect this clean energy to the shore.
The story goes on to discuss OHAs and how they are being developed.
It is very much a must read.
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.
- Sandford Bay occupies the North-East corner of the map.
- The red arrow indicates the main 400kV sub-station at Peterhead.
- 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.
- Flamborough Head is in the North-East corner of the map.
- Wilsthorpe Beach is at Bridlington a couple of miles South of Flamborough Head.
- The red arrow indicates Drax Power station.
- 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.
LionLink: Proposed Windfarm Cabling Sites In Suffolk Are Revealed
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
National Grid has revealed where it wants to build energy infrastructure for cabling between the UK and the Netherlands.
These four paragraphs describe the project.
The power line, called LionLink, would connect offshore wind farms in the North Sea.
The energy company wants the cables to reach land at either Walberswick or Southwold, both in Suffolk.
A converter station would be built on the outskirts of nearby Saxmundham and could cover a six-hectare area.
That would then connect to a substation being built at the village of Friston, also in Suffolk, as part of the offshore wind plans.
But the plans have brought the Nimbies out in force.
This Google Map shows the Suffolk Coast, to the South of Southwold.
Note.
- Southwold and Walberswick in the North-East corner of the map.
- Saxmundham is just up from the South-West corner of the map, with Friston to its East.
- Sizewell with the 1.2 GW Sizewell B nuclear power station is on the coast directly East of Saxmundham.
- Sizewell B is planned to be joined by the 3.2 GW Sizewell C nuclear power station.
- LionLink is likely to have a capacity of 2 GW.
- I also believe that at least another GW of offshore wind power will be squeezed in along this section of coast.
The Sizewell site is connected to the National Grid at Bullen Lane substation to the West of Ipswich.
These pictures show the pylons that were built in the 1960s to connect Sizewell A to the National Grid.
I doubt, they would be allowed to be erected today.
One alternative would be to use T-pylons, like these built to connect Hinckley Point C to the National Grid.
There is more on T-pylons in this press release from National Grid, which is entitled National Grid Energise World’s First T-Pylons.
This Google Map shows the area between Ipswich and the coast.
Note.
- Sizewell is in the North-East corner of the map.
- Felixstowe, Harwich and Freeport East are at the mouth of the rivers Orwell and Stour.
- The Bullen Lane substation is to the West of Ipswich and shown by the red arrow.
Looking at maximum power flows in Suffolk and Somerset, we get.
- North-East Suffolk to the National Grid at Bullen Lane – 7.4 GW.
- Hinckley Point C to the National Grid – 3.26 GW.
I am led to the conclusion, that there need to be a doubling of the pylons between North-East Suffolk and Bullens Lane.
I can understand why the Nimbies have been aroused.
I believe that National Grid will have to take the undersea route along the coast of Essex and Suffolk, to get the electricity to its markets.
Iberdrola Preparing Two East Anglia Offshore Wind Projects For UK’s Sixth CfD Round
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
ScottishPower Renewables, Iberdrola’s company in the UK, is getting the East Anglia One North and East Anglia Two offshore wind projects ready for the upcoming auction round for Contracts for Difference (CfD).
These three paragraphs give more details.
This is according to project updates Iberdrola published as part of its financial results for 2023.
Iberdrola says “good progress is being made in the key engineering and design work” for the two projects and, while they were not presented in the UK’s fifth CfD Allocation Round (AR5), preparations are being made to take part in Allocation Round 6 (AR6).
The two offshore wind farms are part of the GBP 6.5 billion (around EUR 7.6 billion) East Anglia Hub project, which also includes East Anglia Three, currently in construction and expected to start delivering electricity in 2026. The 1.4 GW East Anglia Three was awarded Contract for Difference in July 2022.
It is now possible to build a table of Iberdrola’s East Anglian Hub.
- East Anglia One – 714 MW – Commissioned in 2020.
- East Anglia One North – 800 MW – To be commissioned in 2026.
- East Anglia Two – 900 MW – To be commissioned in 2026.
- East Anglia Three – 1372 MW – To be commissioned in 2026.
Note.
- East Anglia One is the largest windfarm in Iberdrola’s history
- These four wind farms are connected to the shore at Bawdsey on the River Deben.
These wind farms are a total of 3786 MW.
In addition there are RWE’s three Norfolk wind farms.
- Norfolk Boreas – 1386 MW – To be commissioned in 2027.
- Norfolk Vanguard East – 1380 MW – To be commissioned before 2030.
- Norfolk Vanguard West – 1380 MW – To be commissioned before 2030.
These wind farms are a total of 4146 MW, with a grand total of 7932 MW.
What Will Happen To The Electricity?
Consider.
- It is a lot of electricity.
- The good people of Norfolk are already protesting about the cables and pylons, that will connect the electricity to the National Grid.
- The good people of Suffolk will probably follow, their Northern neighbours.
- The wind farms are owned by Spanish company; Iberdrola and German company; RWE.
I wonder, if someone will build a giant electrolyser at a convenient place on the coast and export the hydrogen to Europe by pipeline or tanker.
- The ports of Felixstowe, Great Yarmouth and Lowestoft could probably handle a gas tanker.
- The Bacton gas terminal has gas pipelines to Belgium and The Netherlands.
In addition, there are various electricity interconnectors in use or under construction, that could send electricity to Europe.
- National Grid’s Lion Link to the Netherlands.
- NeuConnect to Germany from the Isle of Grain.
Whoever is the UK’s Prime Minister in 2030 will reap the benefits of these East Anglian and Norfolk wind farms.
In addition.
- The Hornsea wind farm will have tripled in size from 2604 MW to 8000 MW.
- The Dogger Bank wind farm will have grown from 1235 MW to 8000 MW.
- There is 4200 MW of wind farms in Morecambe Bay and around England.
They would be so lucky.
UK And Germany Boost Offshore Renewables Ties
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
A new partnership between the UK and German governments has been agreed on 3 November to help secure safe, affordable, and clean energy for consumers in both nations for the long-term and bolster energy security. Both countries commit to strengthening cooperation in renewables, notably offshore wind and electricity interconnection.
These two paragraphs introduce the deal.
Under the new partnership signed in London by Energy Security Secretary Claire Coutinho and Germany’s Vice Chancellor, Robert Habeck, the UK and Germany have reaffirmed their shared ambition and commitment to net zero and progressing the energy transition.
Europe’s two largest economies have also doubled down on commitments made under the Paris Agreement to limit global warming to 1.5 degrees.
i think this could be a worthwhile follow-up to the relationship, that Boris Johnson and Olaf Scholz seemed to encourage after their high profile meeting in April 2022.
This press release from Downing Street is entitled PM meeting with German Chancellor Olaf Scholz: 8 April 2022 and this is the first two paragraphs.
The Prime Minister welcomed German Chancellor Olaf Scholz to Downing Street this afternoon to discuss the West’s response to Putin’s barbaric invasion of Ukraine.
The two leaders shared their disgust at the Russian regime’s onslaught and condemned Putin’s recent attacks.
I wrote Armoured Vehicles For Ukraine based on some of the things said in the press conference after what seemed to be a very wide discussion.
But it was these paragraphs in the press release that caught my eye.
They also agreed on the need to maximise the potential of renewable energy in the North Sea and collaborate on climate ambitions and green energy.
The Prime Minister said he wanted to further deepen the UK’s relationship with Germany, and intensify its cooperation across defence and security, innovation and science.
After Boris and Olaf’s meeting at Downing Street, I have been able to write these posts about the Anglo-German energy relationship and also make some other observations.
- Mona, Morgan And Morven
- UK-German Energy Link Reaches Financial Close
- RWE, Siemens and other German companies seem to be building a strong presence in the UK.
- Rolls-Royce are doing the same in Germany.
Claire Coutinho and Robert Habeck seem to be wanting to continue the co-operation, judging by this paragraph from the article on offshoreWIND,biz.
The energy and climate partnership sees both countries commit to enhancing cooperation in renewables, particularly in offshore wind and electricity interconnection, including offshore hybrid interconnection.
The most significant part of this paragraph is the mention of offshore hybrid interconnection.
If you want more details on their meeting, this document is the official UK Government declaration.
I have my thoughts.
What Is Meant By Offshore Hybrid Interconnection?
Type “Offshore Hybrid Interconnection” into Google and the first page is this page from National Grid, that is entitled Offshore Hybrid Assets, that has this sub-heading.
How the North Sea has the potential to become Europe’s green energy ‘powerhouse’
This is the introductory paragraph.
Now more than ever we need more renewable energy to make energy cleaner, more affordable, and more secure. The North Sea offers an incredible opportunity for the UK and our European neighbours to deliver huge increases in offshore wind. But delivering new offshore wind will require more infrastructure, which will have an impact on communities.
Hybrid is all-purpose comfort word like cashmere, platinum or puppies.
The page on the National Grid web site describes The Next Generation Interconnector with these paragraphs.
Interconnectors already provide a way to share electricity between countries safely and reliably. But what if they could do much more than that? What if interconnectors could become an offshore connection hub for green energy?
Instead of individual wind farms connecting one by one to the shore, offshore hybrid assets (OHAs) will allow clusters of offshore wind farms to connect all in one go, plugging into the energy systems of neighbouring countries.
And then there is this section entitled Tomorrow’s Solution: Offshore Wind And Interconnectors In Harmony, where this is said.
Today, offshore wind and interconnectors operate alongside each other, connecting to the shore individually. In the future, offshore hybrid assets could enable offshore wind and interconnection to work together as a combined asset.
We now call this type of infrastructure an offshore hybrid asset (OHA), but we used to refer to it as a multi-purpose interconnector (MPI). We changed it because we work so closely together with Europe, it made sense to use the same terminology.
The page on the National Grid web site also has an interactive graphic, which shows the benefit of the approach.
LionLink
National Grid are already developing LionLink, with Dutch grid operator; TenneT, which will be a multi-purpose interconnector linking the UK and the Netherlands.
LionLink is described on this page from National Grid, where this is the sub-heading.
We’re developing a first-of-its-kind electricity link to connect offshore wind between the UK and the Netherlands.
This is the introductory paragraph.
Designed together with our Dutch partners TenneT, LionLink (formerly known as EuroLink) is an electricity link that can supply around 1.8 gigawatts of clean electricity, enough to power approximately 1.8 million British homes. By connecting Dutch offshore wind to Dutch and British markets via subsea electricity cables called interconnectors, LionLink will strengthen our national energy security and support the UK’s climate and energy goals.
Will we be planning a similar electric handshake with the Germans?
How Much Offshore Wind Power Are We Talking About?
This is answered by the last two paragraphs of the article on offshoreWIND.biz.
Around 75 per cent of installed offshore wind capacity in the North Sea is in German and British waters. This is helping to drive the UK’s ambition for up to 50 GW of offshore wind, including up to 5 GW of floating wind, by 2030, the governments said.
Germany is aiming at installing 30 GW by 2030.
That is an Anglo-German starter for eighty GW.
Electrolysers In The Middle If The North Sea
Why Not?
This is a clip from National Grid’s graphic on the page that introduces Offshore Hybrid Assets,
It shows an offshore hydrogen electrolyser.
- You could have an offshore hybrid asset that went between say Bacton in Norfolk and Hamburg via these assets.
- One or more wind farms in UK territorial waters.
- A mammoth offshore electrolyser, with hydrogen storage, possibly in a depleted gas field.
- One or more wind farms in German territorial waters.
Electricity will be able to go three ways; to the UK, to Germany or to the electrolyser.
The Involvement Of German Energy Companies In UK Territorial Waters
Wikipedia lists offshore fifteen wind farms, that have German owners in UK territorial waters, that total 12,960 MW.
This compares with.
- Equinor – 6 wind farms totalling 6466 MW.
- Ørsted – 15 wind farms totalling 9683 MW.
- Scottish Power – 2 wind farms totalling 5,000 MW.
- SSE Renewables – 15 wind farms totalling 15,591 MW.
- Vattenfall – 6 wind farms totalling 4384 MW.
As there is a number of partnerships, these figures only show the relative sizes of the investment by individual companies.
But at nearly 13 GW, the amount of total German investment in UK territorial waters is substantial.
Is This Solely An Anglo-German Club Or Can Others Join?
Consider.
- It seems to me, that because of the LionLink, the Dutch are already involved.
- TenneT is also a large electricity distributor in Germany.
- Countries with substantial shares of the water and winds of the North Sea in addition to Germany, the Netherlands and the UK, include Belgium, Denmark and Norway.
- The UK has interconnectors with Belgium, Denmark, France, Germany, Norway and the Netherlands.
It appears that the world’s largest multi-national power generator is evolving by stealth.
North Sea Wind Power Hub
This concept seems to have developed around 2017, by Danish, Dutch and German interests.
The Wikipedia entry introduces it like this.
North Sea Wind Power Hub is a proposed energy island complex to be built in the middle of the North Sea as part of a European system for sustainable electricity. One or more “Power Link” artificial islands will be created at the northeast end of the Dogger Bank, a relatively shallow area in the North Sea, just outside the continental shelf of the United Kingdom and near the point where the borders between the territorial waters of Netherlands, Germany, and Denmark come together. Dutch, German, and Danish electrical grid operators are cooperating in this project to help develop a cluster of offshore wind parks with a capacity of several gigawatts, with interconnections to the North Sea countries. Undersea cables will make international trade in electricity possible.
Currently, the UK is developing these wind farms on their portion of the Dogger Bank.
- Doggerbank A – 1235 MW – Started producing electricity in 2023.
- Doggerbank B – 1235 MW – Planned commissioning in 2024.
- Doggerbank C – 1218 MW – Planned commissioning in 2025.
- Doggerbank D – 1320 MW – Being planned.
- Doggerbank South – 3000 MW – Being planned.
Note.
- That’s a total of 8 GW.
- A, B, C and D are being developed by a consortium of SSE Renewables and Equinor.
- South is being developed by RWE.
- This web site is for Dogger Bank D.
- This web site is for Dogger Bank South.
This map from the European Atlas of the Seas, shows the various exclusive economic zones (EEZ) in the North Sea.
Note.
- The pinkish zone to the East of the UK, is the UK’s EEZ.
- The light blue zone at the top is Norway’s EEZ.
- The greenish zone in the North-East corner of the map is Denmark’s EEZ.
- The light blue zone below Denmark’s EEZ is Germany’s EEZ.
- Then we have the EEZs for The Netherlands, Belgium and France.
The Dogger Bank is situated where the British, Dutch, German and Norwegian EEZs meet.
All five Dogger Bank wind farms are in British waters.
The Wikipedia entry for the Dogger Bank says this about its size.
The bank extends over about 17,600 square kilometres (6,800 sq mi), and is about 260 by 100 kilometres (160 by 60 mi) in extent. The water depth ranges from 15 to 36 metres (50 to 120 ft), about 20 metres (65 ft) shallower than the surrounding sea.
This probably makes it easy to accommodate a large fixed-foundation wind farm.
Overlaying the map in the Wikipedia entry, with the EEZ map, I’m fairly sure that the northeast end of the Dogger Bank is close to where the EEZs meet.
Progress On The North Sea Wind Power Hub
The North Sea Wind Power Hub has a web site, but it seems to be more about thinking than doing.
It seems to have been hijacked by that august body; The Institute of Meetings Engineers.
This page on the web site, which is entitled Explore The Future Energy Highways, has a simple interactive map.
This shows its vision for 2030.
Note.
- Yellow is electricity links to be built before 2030.
- Blue is hydrogen links to be built before 2030.
- Feint lines indicate the EEZ boundaries.
There are two problems with this layout.
- It doesn’t connect to the Dogger Bank area, where the original plan as detailed in Wikipedia talked about “Power Link” artificial islands.
- No hydrogen is delivered direct to Germany.
This shows its vision for 2050.
Note.
- Yellow, blue and feint lines are as before.
- White is electricity links to be built before 2050.
- There appears to be a node on the Dogger Bank in the German EEZ. This node could be connected to the “Power Link” artificial islands.
- The Southernmost connection to East Anglia could be Bacton.
- The other Norfolk connection could be where wind farms are already connected.
- The Northern connection could be Teesside, where some of the Dogger Bank wind farms connect.
- If the Northern connection to England is Teesside, then first node, which is in the British EEZ, could be one of the offshore sub-stations in the Dogger Bank wind farm complex.
This all seems a lot more feasible.
A New Offshore Hybrid Asset Between Teesside And Germany
Consider.
- A new offshore sub-station will be needed in the German EEZ to connect the “Power Link” artificial islands to the power network.
- The new offshore sub-station will eventually have three interconnectors to the German coast.
- Only the 1218 MW Dogger Bank C wind farm will be connected to the Teesside onshore substation.
- Germany has a power supply problem, after shutting down nuclear power stations and building more coal-fired power stations.
A new Offshore Hybrid Asset between Teesside and Germany could be created by building the following.
- A the new offshore sub-station in the German EEZ to connect the “Power Link” artificial islands to the power network.
- An interconnector between a sub-station of the Dogger Bank wind farm complex and the new sub-station
- A second interconnector to connect the new sub-station for the “Power Link” artificial islands to the German electricity grid.
All of the work would be done mainly in the German EEZ, with a small amount in the British EEZ.
Where Does Dogger Bank South Fit In?
Consider.
- Dogger Bank South is planned to be a 3 GW wind farm.
- It will need a 3 GW connection to the onshore electricity grid.
- Creyke Beck substation is the proposed location for the onshore connection.
- It is owned by German electricity company; RWE.
Could it be that some of the electricity produced by Dogger Bank South is going to be sent to Germany or to another node to produce hydrogen?
It certainly illustrates the value of an Offshore Hybrid Asset.
Is Sizewell C Needed?
I am generally pro-nuclear, but I am not sure if building a large nuke at Sizewell is the right action.
Consider.
- East Anglia has 3114 MW of offshore wind in operation.
- East Anglia has 6772 MW of offshore wind under construction, with Contracts for Difference or proposed.
- Vattenfall are considering abandoning development of their large wind farms off the Norfolk coast, which are proposed to have a capacity of 3196 MW.
- If the two Vattenfall wind farms don’t get built, it is likely that East Anglia will have around 6700 MW of offshore wind capacity.
- Sizewell C has a proposed nameplate capacity of 3260 MW. Some might argue, that to back up East Anglia’s offshore wind power, it needs to be larger!
- Norfolk and Suffolk no large electricity users, so are Vattenfall finding they have a product no one wants to buy.
- National Grid is developing four interconnectors to bring power from Scotland to the Eastern side of England, which will back up wind power in the East with the massive Scottish pumped storage, that is being developed.
- National Grid and their Dutch equivalent; TenneT are developing LionLink to connect the UK and the Netherlands to clusters of wind farms between our countries in the North Sea.
- Kent and East Anglia have several gas and electric interconnectors to Europe.
- Sizewell is well-connected to England’s grid.
These are my thoughts.
Energy Storage At Sizewell
Consider.
- Sizewell is well connected to the grid.
- It has the sea on one side.
- It could easily be connected to the large offshore wind farms, thirty miles out to sea.
If large energy storage could be built on the Sizewell site or perhaps under the sea, then this energy could be recovered and used in times of low wind.
Perhaps the technology of the STORE Consortium, which I discussed in UK Cleantech Consortium Awarded Funding For Energy Storage Technology Integrated With Floating Wind, could be used.
In this system, energy is stored in 3D-printed concrete hemispheres under the sea.
A Small Nuclear Reactor Cluster At Sizewell
Rolls-Royce are proposing that their small modular reactors will have a capacity of 470 MW.
Perhaps a cluster of seven small modular reactors at Sizewell, with a building schedule matched to the need to back up wind farms would be better and easier to finance.
I also feel a cluster of SMRs would have less risk and would be less likely to be delayed.
Where Is Generating Capacity Needed In The UK?
These areas already have large amounts of offshore wind in operation or proposed to be built before 2030.
- Celtic Sea
- North Wales
- Liverpool Bay
- Cumbria
- Scotland
- Scotland’s Offshore Islands
- North East England
- Humberside
- Lincolnshire
- East Anglia
- Thames Estuary
- Kent
- Sussex
Amongst the back up for these wind farms, there are only two modern nuclear stations; Sizewell B and the still-to-open Hinckley Point C.
If you look at a map of England and its power generation, there is a tremendous gap of capacity South of a line between Hinckley Point and Brighton, with little or no offshore wind and no nuclear.
There is probably a need for a large nuke near Weymouth.
Alternatively, perhaps several SMRs could be built underneath places like Salisbury Plain, Dartmoor and Exmoor!
Conclusion
We probably need the nuclear electricity from another Hinckley Point C-sized nuclear power station, so that we have adequate back-up for offshore wind.
But I am not sure that Sizewell is the right place to build it.
Ireland To Develop National Industrial Strategy For Offshore Wind
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Ireland’s Minister for Enterprise, Trade and Employment, Simon Coveney, has announced plans to develop a National Industrial Strategy for Offshore Wind which will set out how Ireland can maximise the economic opportunity arising from the production of offshore wind energy
Ireland’s current objectives for offshore wind are.
- To deliver 5 GW of offshore wind by 2030.
- A further 2 GW of floating wind to be in development by 2030.
- The target for offshore wind could rise to at least 37 GW by 2050.
- There is a target to provide 80 per cent of the country’s electricity to be from renewable sources by 2030.
The government appears to recognise collaborative approach between state and industry is needed.
Nothing is said about co-operation with Northern Ireland or the UK.
This is despite.
- UK and Irish companies like ESB, Flotation Energy, Simply Blue Group and SSE have projects in both countries.
- Irish company; ESB is developing the Malin Sea Wind wind farm in Scottish waters and landing the electricity near Derry City.
- Scottish company; SSE is building biomass power stations in Ireland.
- Some promising waters for wind power are shared between the two countries.
- There are three interconnectors between the two main islands.
I would expect that there could be some multi-purpose interconnectors across the Irish and Celtic Seas.
These would connect windfarms between the islands to both the UK and Ireland. National Grid and TenneT are building the LionLink between England and The Netherlands, which I wrote about in World’s Largest-Of-Its-Kind Power Line To Deliver Clean Power To 1.8m UK Homes And Boost Energy Security.
I very much feel, that there will be a lot of co-operation between the UK and Irish governments as if they work together, the development of Ireland’s offshore wind and that of the West Coast of the UK could be more efficient.
