Opportunity For Communities To Have Their Say On New Clean Energy Substation Proposed Near Chesterfield
The title of this post, is the same as that of this article on National Grid.
These three bullet points act as sub-headings.
- National Grid is consulting communities from 22 April to 20 May 2024 on its plans for a new electricity substation which will strengthen its network and connect clean energy to the grid – part of The Great Grid Upgrade
- Substation crucial to upgrade critical infrastructure and ensure a secure and reliable supply of clean energy
- Local people invited to attend consultation events to learn more about the proposals
This is the first paragraph.
National Grid is making changes to its network of electricity infrastructure that transports power around the country, in order to connect new sources of power generated from offshore wind and other low carbon sources to the homes and business across Britain.
These two paragraphs detail the work at Chesterfield.
The Great Grid Upgrade is the largest overhaul of the grid in generations. It will play a large part in the UK government’s plan to boost homegrown power, helping the UK switch to clean energy and make sure our electricity network is fit for the future; carrying more clean, secure energy from where it’s generated to where it is needed.
As part of the Brinsworth to High Marnham project, National Grid is proposing to build and operate a new 400kV substation which will extend to the south of its existing substation site off Calow Lane in Cock Alley, near Chesterfield in Derbyshire. The new substation, which forms a key part of The Great Grid Upgrade, will play an important role in building a more secure and resilient future energy system and provide the ability to transport cleaner energy from the North of England to homes and businesses across the Midlands and beyond, helping to reduce our reliance on fossil fuels.
This is a 3D Google Map of the current sub-station.
Note.
- Four pylons can be seen.
- The image is shown looking North.
- The new substation will be on this side of the current substation.
It certainly will be a large substation.
The Consultation
There is a web site, a webinar and a local in-person meeting.
The local meeting is on Friday 10 May from 2pm – 7pm and Saturday 11 May from 9am – 2pm at Calow Community Centre, Allpits Road, Calow, Chesterfield S44 5AT
- Friday 26 April from 2pm – 7pm at South Clifton Coronation Hall, South Clifton, Newark, Nottinghamshire, NG23 7BG
- Saturday 27 April from 9am – 2pm at Normanton on Trent Village Hall, South Street, Normanton on Trent, NG23 6RQ
This is the third Opportunity For Communities To Have Their Say in a few days.
This is probably sufficient consultation.
Opportunity For Communities To Have Their Say On National Grid Proposals For Norwich To Tilbury Project
The title of this post is the same as that of this press release from National Grid.
These three bullet points are sub-headings.
- National Grid is consulting communities for 10 weeks, between Wednesday 10 April to Tuesday 18 June, on its infrastructure proposals to connect new clean energy sources into the East Anglian electricity network.
- Norwich to Tilbury will enable National Grid to connect the sources of power generated from offshore wind to homes and businesses across Britain, helping to reduce our reliance on fossil fuels and bring the cost of energy bills down.
- The project will help the UK achieve its aim of generating 50GW of energy from offshore wind by 2030 and reach net zero by 2050.
This page on the National Grid web site has an interactive map of the route.
This paragraph invites people to comment.
National Grid is encouraging communities in East Anglia to comment on proposals to upgrade the high voltage power network in England as part of a 10-week consultation process which runs between Wednesday 10 April and Tuesday 18 June.

I shall be going to the Brentwood and Needham Market meetings.
I have some thoughts.
T-Pylons
There is a chance that this route will not use conventional pylons.
These pictures show the T-pylons, that have been used in Somerset to connect Hinckley Point C power station to the National Grid.
Note.
- They are a Danish design.
- They are shorter than current pylons.
- They have a smaller footprint on the ground.
- The design won a National Grid-RIBA design competition.
- We will probably see them around the country in the next few years.
They are certainly better than the standard ones that connect the Sizewell site to the National Grid, that passed by my first house in Suffolk.
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.
- These add up to a total of 77,316 MW.
- 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.
- 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.
- The colours are the same, as the previous map.
- Although, I do think there are some errors in which have been used.
- 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.
- 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.
£400k For National Grid Innovation Projects As Part Of Ofgem Fund To Help Shape Britain’s Net Zero Transition
The title of this post, is the same as that, of this press release from National Grid.
These three bullet points, act as sub-headings.
- Three transmission and distribution network innovation projects receive green light
- Funding kickstarts projects for the discovery phase of Ofgem innovation scheme
- 14 National Grid projects worth £4m have won innovation funding since scheme began
These are the three projects.
HIRE – Hybrid-Network Improvement & Reliability Enhancement
This is National Grid’s description of the £135,000 project.
Researching new state-of-the-art condition monitoring to improve the commissioning and operation of offshore cables. This new, robust system will mitigate the risk of failure, overcome the limitations of existing techniques (e.g. cable length) and aid network operators in decision making for a more flexible grid. PROJECT PARTNERS: University of Manchester, DNV, Monitra, SSEN Transmission.
With all the offshore cables, that have been laid around the UK, Europe and the world in recent years, I am surprised that such a system has not been developed before.
But I suspect, that the project partners know that if they can develop a superior cable monitoring system, then it could be a nice little earner in addition to its job with UK offshore cables.
According to their web site, Monitra seem to be the monitoring experts.
This is the mission statement on their home page.
Our aim is to maximise the uptime of every high voltage asset worldwide.
I like this company’s attitude and it should make the world a better place.
I certainly think that the £135,000 will be well spent.
REACH – Rural Energy And Community Heat
This is National Grid’s description of the £120,000 project.
Working with rural community energy groups to develop a modular rural energy centre that will help communities make cost effective decarbonisation plans. The solution will offer shared low carbon heating, rapid EV charging, and renewable generation in areas not served by commercial markets, and where there is limited electricity network capacity.
Rolls-Royce mtu seem to have a system, that might go some way to satisfy National Grid’s ambitions, that I wrote about in Would You Buy A Battery Energy Storage System From Rolls-Royce?.
Road to Power
This is National Grid’s description of the £140,000 project.
Developing specific tools to forecast future energy consumption and infrastructural impact of works, to support the street and road works sector as it decarbonises 7.8TWh of energy demand across 700,000 major works in the sector’s pivotal transition to net zero by 2030.
This sounds like an excellent idea. Especially, if it makes street and road works quieter and less polluting.
Conclusion
I like these three projects and have already added them to my list of Google Alerts.
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.
Contracts Signed For Eastern Green Link 2 Cable And Converter Stations
The title of this post, is the same as that of this press release from National Grid.
These four bullet points, act as sub-headings.
- 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
- The joint venture has signed a contract with the Prysmian Group to supply around 1,000km of cable for the project and a contract with Hitachi Energy and BAM for the supply of converter stations at either end of the subsea cable
- Contract signing is a significant milestone for the project as it progresses towards the delivery phase
- EGL2 will be the longest HVDC cable in the UK and the UK’s single largest electricity transmission project ever, providing enough electricity to power two million UK homes
This paragraph outlines the project.
EGL2, a joint venture between SSEN Transmission and National Grid Electricity Transmission (NGET), has reached another milestone in the development of a new subsea electricity superhighway after sealing contracts this week with specialist HVDC cable supplier, Prysmian, and with Hitachi Energy and BAM for the supply of converter stations at either end of the project.
These four paragraphs add more detail.
EGL2 will see the creation of a 525kV, 2GW HVDC subsea transmission cable from Peterhead in Scotland to Drax in England. The longest HVDC cable in the UK and the UK’s single largest electricity transmission project ever, it will provide enough electricity to power two million UK homes.
Prysmian has confirmed it has the capability to deliver the project with its manufacturing facilities for the production of the HVDC cable and its cable laying vessels for the installation in the timescale required for EGL2 to meet its targeted energisation date in 2029, supporting the timely delivery of this project and mitigating risks associated with global constraints in the HVDC supply chain.
Hitachi Energy is partnering with BAM to provide the engineering works and technology for the HVDC converter stations which form the terminals for the HVDC cable and convert direct current to the alternating current used in the onshore transmission network. This latest milestone is another significant step as the project moves towards delivery and, following final approval from Ofgem, work is expected to commence later this year, with a targeted operational date of 2029.
The subsea HVDC cable system is approximately 436km in length with new converter stations at either end to connect it into the existing transmission network infrastructure. HVDC technology provides the most efficient and reliable means of transmitting large amounts of power over long distances subsea.
Note.
- EGL2 can handle 2 GW.
- There is a targeted operational date of 2029.
- Eastern Green Link 2 now has its own web site.
- Most of these links now seem to be HVDC.
A map in the press release, shows the undersea route may be shorter.
It also appears to me, that moving electricity around the UK under the sea, is possibly the most environmentally-friendly and least intrusive way to do it.
We already have four HVDC interconnectors.
There will be many more,
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.
Energy Security Boost After Centrica And Repsol Agree LNG Supply Deal
The title of this post, is the same as that of this press release from Centrica.
This is the sub-heading.
Centrica Energy and Repsol today announced the signing of a deal that will improve the UK’s energy security in the coming years.
These two paragraphs give more details of the deal.
The deal will see Centrica purchase 1 million tonnes of Liquified Natural Gas (LNG) shipments between 2025 and 2027. All of these cargoes are expected to be delivered to the Grain LNG import terminal in Kent.
The deal marks an additional move by Centrica to build further resilience in the UK’s energy security. It follows a 15 year, $8bn deal with Delfin Midstream in July 2023, a three-year supply agreement with Equinor that will heat 4.5m UK homes through to 2024 and the reopening and expansion of the Rough gas storage facility in October 2022 and June 2023 respectively. Rough now provides half of the UK’s total gas storage capacity with the potential to store over 50 billion cubic feet (bcf) of gas, enough to heat almost 10% of UK homes throughout winter.
Centrica do seem to be keeping us supplied with gas.
Two days ago, National Grid published this press release, which is entitled Grain LNG Signs New Deal With Venture Global Further Strengthening The Security Of Supply Of LNG To The United Kingdom.
This is the sub-heading.
Today (5 February), Grain LNG and Venture Global have announced the execution of a binding long-term terminal use agreement (TUA) enabling the regasification and sale of LNG from all of Venture Global’s LNG terminals in Louisiana, including CP2 LNG, subject to obtaining necessary federal permits.
These two paragraphs give more details of the deal.
Under the agreement, Venture Global will have the ability to access 3 million tonnes per annum (3MTPA) of LNG storage and regasification capacity at the Isle of Grain LNG receiving terminal for sixteen years beginning in 2029, equivalent of up to 5% of average UK gas demand.
This is the second agreement from Grain LNG’s competitive auction process which was launched in September 2023. The successful outcome of the auction further secures the future of Europe’s largest LNG import terminal into the mid 2040s.
Two big deals in the same week is not to be sneezed at and must be good for the UK’s energy security.
