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.
German Company To Build XXL Monopile Factory in Denmark
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
German-based Baltic Structures Company (BSC) has revealed that it will build an XXL monopile production factory in Esbjerg, Denmark
These are the first three paragraphs that outline the project.
BSC will build “Europe’s biggest” foundation fabrication site in the Esbjerg Port where it will be able to offer various foundations structures with a more than 100,000-square-metre production area under the roof and an output of up to 200 XXL monopiles per year.
The German company said that the focus of the plant is on structures with dimensions of up to 15 metres in diameter, up to 130 metres in length, and single unit weights of up to 4,000 tonnes.
In addition to monopiles, transition pieces, pin piles, and components for jackets, floating foundations will also be offered, said BSC.
These last three paragraphs sum up, where we are at the moment with European wind turbine foundation manufacture.
In September 2022, Esbjerg Port (Denmark), Oostende Port (Belgium), Groningen Seaports/Eemshaven (the Netherlands), Niedersachsen Port/Cuxhaven (Germany), Nantes-Saint Nazaire Port (France), and Humber (the UK) signed a partnership agreement with an aim to minimise capacity issues.
At the beginning of this year, the six largest European wind ports also signed a mutual declaration to collaborate on an operational and practical level to help bring the new offshore wind capacities across Europe as smoothly as possible.
In January, the Port of Esbjerg, together with US-based Moffatt & Nichol, deployed digital twin technology which could triple the port’s offshore wind capacity.
I also wrote UK And South Korea Help Secure Millions For World’s Largest Monopile Factory, this morning about a new monopole factory on Teesside.
- The Teesside factory is described as the world’s largest.
- On the other hand the Esbjerg Port facility is described as Europe’s biggest foundation fabrication site.
I suspect the Germans and the Koreans are using different engineering dictionaries.
European Offshore Wind Power Targets
Out of curiosity, I looked up the offshore wind capacity, the UK and neighbouring countries are planning before 2030.
- UK – 50 GW
- Germany – 30 GW
- Norway – 30 GW
- The Netherlands – 21 GW
- France – 18 GW
- Denmark – 13 GW
- Italy – 10 GW
- Portugal – 10 GW
- Belgium – 5.4-5.8 GW
- Republic of Ireland – 5 GW
- Spain – 3 GW
Note.
- Norway’s figure relates to 2040.
- Northern Ireland have a target of 1 GW, which I assume is included in the UK total.
- The total is between 195.4 and 195.8 GW.
Given that we could be producing over a quarter of Western Europe’s offshore wind power, the Gods of the Winds must have been British.
Denmark Exploring Multiple Platforms As Alternative To Building Artificial Island
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
After concluding that the current concept of its North Sea Energy Island would be too expensive for the State, the Danish government, the transmission system operator (TSO) Energinet, and other relevant agencies are now looking into the concept for the island to be established on several large platforms.
I feel this could be a sensible decision, as it would fit well with a modular approach to the building of offshore wind farms.
Suppose, the floating turbines used by a company like Ørsted were all similar. This would surely simplify management of their portfolio of wind farms.
If it works for floating wind turbines, surely, it would work for substations, electrolysers and other offshore hardware.
Conclusion
Artificial energy islands may seem an impressive way to go, but I suspect that the modular approach using standard components, that either sit on the sea bed or float may be a more affordable and faster way to build offshore wind farms.
British Five-Year-Olds Up To 7cm Shorter Than Western Peers
The title of this post, is the same as that of this article in The Times.
This is the sub-heading.
Poor diet and health service cuts blamed for ‘pretty startling’ trend
These are the first two paragraphs.
Five-year-olds in Britain are on average up to seven centimetres shorter than their peers in other wealthy nations, in a trend described as “pretty startling”.
A poor national diet has been highlighted as a major culprit in Britain’s fall down international rankings of child height.
I am coeliac and am only 170 cm.
During the pandemic, I did some statistical research on coeliac disease and the covids for my own interest.
I found a peer-reviewed Indian medical paper entitled Coeliac Disease: Can We Avert The Impending Epidemic In India? The author felt that modern high-gluten wheats, were increasing the rate of the disease.
The author also said this about introduction gluten to babies in Sweden.
The time of first exposure to wheat influences the development of celiac disease. In countries such as Finland, Estonia, and Denmark, characterized by low gluten consumption in infancy, celiac disease prevalence is much lower than in Sweden where gluten consumption is high in infancy. A natural experiment occurred in Sweden about two decades ago when national recommendations were made to introduce wheat into the diet after cessation of breast feeding at six months. This change was coupled with increased wheat gluten consumption through infant feeds. Together these measures resulted in a two-fold increase in incidence of celiac disease in Sweden, which was attributed to introduction of wheat into the diet after cessation of breast feeding. In 1996 this recommendation was changed to introduce gluten in gradually increasing amounts while the infant was still being breast fed. This led to a dramatic decrease in celiac disease incidence.
It is interesting to look at heights of five-year-olds given in the Times article for the four countries.
- Denmark – 117.4 – 118.1
- Estonia – 116.9 – 115.7
- Finland – 116.3 – 114.5
- Sweden – 115.1 – 115.1
Note that all heights are in centimetres, with boys first.
As according to the graphs in the article the UK and the US have shown the biggest declines in height, is gluten-rich junk food, the major cause of this decline?
More research needs to be done!
Denmark And Germany Sign Bornholm Energy Island Agreement, First Legally Binding Cooperation On Joint Offshore Renewable Energy Project In EU
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
German Federal Minister for Economic Affairs and Climate Action, Robert Habeck, and Danish Minister for Climate, Energy and Utilities, Lars Aagaard, have signed an agreement for the Bornholm Energy Island in the Baltic Sea. This is the first legally binding cooperation agreement in Europe on a joint offshore energy project under the EU Renewable Energy Directive.
Bornholm is a Danish island between Denmark, Germany and Sweden, as this map shows.
Note.
- Malmo is in Sweden.
- Copenhagen is in Denmark.
- Germany is in the South-West corner of the map.
Bornholm is the island in the North-East corner of the map.
This paragraph gives the bare details of the generation and transmission capacities.
Bornholm Energy Island, located in the Danish sector of the Baltic Sea, will facilitate connecting at least 3 GW of offshore wind generation capacity to the grid by the early 2030s. The electricity will then be transported via new grid connections to Germany (2 GW ) and to the Danish mainland (1.2 GW).
The great advantage of an energy island, is that the electricity can be sent both ways according to where it is needed.
Some of the energy islands that have been proposed also include energy storage and/or hydrogen production.
This web site gives more details of the Bornholm Energy Island.
Under a heading of Why Build Energy Islands?, these reasons are given.
- Environment and climate
- Energy security in Europe
- Inspiration for the world
Under a heading of What is an Energy Island?, this is said.
An energy island makes it possible to establish large wind farms at sea far from the coast. The energy produced by the wind turbines is sent via cables to the energy island, from where it is sent out to consumers. On Bornholm, a high-voltage facility must therefore be established on the island which can receive and distribute the electricity. After that, green power can be sent from Bornholm to millions of consumers in Denmark and Germany. Bornholm’s Regional Municipality is working hard to seize the energy island’s potential for job creation and local business growth, and in turning Bornholm into the green business beacon and transport hub for green fuels in the Baltic Sea.
I suppose it could be argued that in the UK, Orkney and Shetland are already energy islands and will become more so in years to come.
Energy islands, whether real or man paid certainly seems to be a concept that is growing in populatity, with several being developed.
Vattenfall: Dolphins Unfazed By Offshore Wind Construction Work
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Concerns have been raised that the installation of the monopiles of the Vesterhav North wind farm offshore Denmark could cause a small pod of dolphins to leave the area. The dolphins have, however, neither left the area nor have they changed their behaviour, Vattenfall, the owner and developer of the wind farm, said.
These are the first two paragraphs.
In 2020, wildlife and underwater photographer Lars Mikkelsen discovered a pod of seven Common Bottlenose dolphins during a sailing trip in the canal between the North Sea and the Limfjord at the Danish coastal town of Thyborøn. Since then, Mikkelsen has been closely following the dolphins that are rare guests in the seas around Denmark.
The small pod of dolphins has for the past three years established residence in the area of the Danish part of the North Sea where Vattenfall is constructing its Vesterhav offshore wind farms.
This Google Map shows the Limfjord, which stretches between the North Sea and the Kattegat.
Thyborøn, is at the Western entrance to the Limfjord, which leads into the large area of water in the South-West of the map.
From its Wikipedia entry, the Limfjord seems to be an ecologically-interesting place.
This paragraph sums up how the construction affected the dolphins.
So, when concerns were raised that the installation of the wind farm’s monopiles could cause the dolphins to leave the area, Vattenfall initiated a collaborative monitoring effort. Fortunately, it showed that the dolphins were still present and have not changed behaviour after completion of the monopile installation.
Note.
- Vattenfall did adopt measures to mitigate the noise, as is detailed in the article.
- A university also took a series of measurements.
But the exercise does show it is possible to install offshore wind farms without disturbing the inhabitants.
Shell Joins VindØ Energy Island Consortium
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Global energy major Shell is joining the VindØ consortium which is aiming to take a leading role in developing and building Denmark’s first energy island.
This paragraph outlines the project.
The island will be able to connect 10 GW of offshore wind to Denmark and other neighboring countries, plus host an innovation zone with potential for large-scale Power-to-X production and energy storage. It would include accommodation and operation and maintenance services from onsite harbour facilities.
It looks spectacular in the visualisation.
Thor Offshore Wind Farm To Feature Siemens Gamesa’s Newly Launched GreenerTowers
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Siemens Gamesa has revealed its GreenerTower, a wind turbine tower made of more sustainable steel. The company already closed its first order with RWE to feature 36 of the GreenerTower units at the 1 GW Thor offshore wind project in Denmark.
This is the first paragraph.
Today, tower production accounts for more than one-third of all wind-turbine-related CO2 emissions, according to Siemens Gamesa.
Siemens Gamesa’s new GreenerTower will ensure a CO2 reduction of at least 63 per cent in the tower steel plates compared to conventional steel.
Siemens Gamesa also claim this.
If all towers installed by the company in one year were exchanged with GreenerTowers, it would be the same as removing more than 466,000 cars from the roads in Europe for a year.
The first supplier to be qualified is Salzgitter AG.
- I wrote about Salzgitter’s green steelmaking in WindH2 Hydrogen Project Commissioned In Germany.
- Only a maximum of 0.7 tonnes of CO2-equivalent emissions are permitted per tonne of steel while maintaining the same steel properties and quality.
- Salzgitter’s electric furnaces will be fed with green electricity produced by renewable energy sources.
- Salzgitter AG have recently signed a Power Purchase Agreement (PPA) with Iberdrola.
- It looks like Salzgitter AG are going both the electric and hydrogen route to green steel.
I suspect over the next few years, we’ll be seeing more steel products made with green steel.
In this case, I suspect that Siemens Gamesa could use the same production process with very little modification, which is a great advantage.
World’s Largest-Of-Its-Kind Power Line To Deliver Clean Power To 1.8m UK Homes And Boost Energy Security
The title of this post, is the same as that as this press release from the UK Government.
These are the three bullet points of the press release.
- LionLink power line between UK and Netherlands will deliver enough electricity to power more homes than Manchester and Birmingham combined.
- Agreement made as Grant Shapps leads delegation of leading businesses to key North Sea Summit.
- Part of renewed Government drive to work with business to help grow the economy.
These three paragraphs outline the project.
The world’s largest multi-use electricity power line will be built under the North Sea, boosting UK energy supplies with enough to power 1.8 million homes – more than Birmingham and Manchester combined.
The new LionLink will connect the UK and the Netherlands with offshore wind farms, providing clean affordable and secure energy to Britain which will help cut household bills and drive Putin’s Russia further out of the energy market.
The cross-border electricity line will be only the second of its kind in the world, with the first having been built by Germany and Denmark. However, it will be able to carry more than four times the amount of electricity as its predecessor – making it the largest of its kind in terms of capacity anywhere in the world.
Note.
- I suspect the LionLink will go via the Dogger Bank, where Danish, Dutch, German and UK territorial waters meet an we are already building 8 GW of fixed foundation offshore wind. The other countries are also active in the area.
- The press release doesn’t mention, where the LionLink will make landfall in the UK.
- Much of the connection will probably use the cables being laid for the Dogger Bank wind farms.
- There is also no mention of the North Sea Wind Power Hub, which could be an artificial island on the Dogger Bank.
There is also a press release on the National Grid web site, which is entitled National Grid And TenneT Collaborate On Proposed First-Of-A-Kind Anglo-Dutch Electricity Link, which gives more details.
- The capacity is stated to be 2 GW.
- Like the current BritNed interconnector, the project will be a cooperation between National Grid And TenneT.
- TenneT is a limited liability company owned by the Dutch government, that is a transmission system operator in the Netherlands and in a large part of Germany.
There is also a diagram, showing how the LionLink will work, which includes these components.
- On the Dutch side, there is an offshore AC>DC Converter Station, which is connected to the Dutch electricity grid and one or more offshore wind farms.
- Across the border between the Dutch and UK Exclusive Economic Zones, there will be a HVDC cable.
- The HVDC cable will terminate in an onshore DC>AC Converter Station in the UK, which will be connected to the UK electricity grid.
No details of the two landfalls have been given.
More information is given in this article on offshoreWIND.biz, which is entitled UK And Netherlands Unveil Multi-Purpose Interconnector Plans.
- This shows a map of the North Sea with an interconnector running in a straight line between possibly Rotterdam and Bacton in Norfolk.
- A wind farm is shown connected to this interconnector.
This paragraph describes the windfarm and the interconnector.
LionLink, a multi-purpose interconnector that was announced today at the North Sea summit, could connect a Dutch offshore wind farm with a capacity of 2 GW to both countries via subsea interconnectors.
If the wind farm has a capacity of 2 GW, I would assume it can supply up to 2 GW to the UK and The Netherlands.
This is a classic system, that can be optimised by the application of sound principles.
All electricity generated by the wind farm must be used, stored or converted into green hydrogen.
Electricity will be distributed as to need.
Energy storage or electrolysers could be sited at either end or even in the wind farm.
I would suspect that more wind farms could be connected to the interconnector.
The team, that write the control system for the grid will have a lot of fun!
BritNed
I have a feeling that National Grid and TenneT have taken a long hard commercial look at the electrical and financial performance of BritNed over the last year and decided, that a second connection would be to the mutual benefit of both companies, their customers and the UK and The Netherlands in general.
It would also be twice as difficult for terrorists sponsored by Putin to cut two cables.
Conclusion
This is a great leap forward for wind power in the North Sea and Europe.
Denmark Launches World’s First Power-to-X Tender
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Danish Energy Agency (DEA) has invited bids to build and operate Power-to-X projects with a deadline for applications set to 1 September. Through the tender – the first of this kind in both Denmark and the world – the country has made available DKK 1.25 billion (approximately EUR 167.7 million) in state support for the production of Power-to-X in the form of green hydrogen.
This paragraph outlines the deal.
The tender is being held to procure hydrogen produced by using renewable energy sources and is part of Denmark’s goal to reach between 4 and 6 GW of electrolysis capacity by 2030 and its Power-to-X strategy, released in 2021, according to which the country’s offshore wind resources provide good conditions for the production of green hydrogen, which requires large amounts of green electricity.
These are the conditions.
- Only hydrogen that is produced from renewable energy sources and meets the EU’s documentation requirements for green PtX fuels is eligible for support.
- The winning bidder(s) must have the project(s) built to full capacity and start green hydrogen production within four years of signing the contract with the Danish Energy Agency.
The tender has been approved for state aid by the European Commission.
I can see all the large electrolyser builders getting their bids ready for what will be tough competition.
The Anonymous Widower
