UK Gov’t Tweaking CfD Rules Ahead Of 8th Allocation Round, Proposes ‘Other Deepwater Offshore Wind’ Category
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The UK government has launched a consultation on proposed refinements to the Contracts for Difference (CfD) scheme ahead of Allocation Round 8 (AR8) and future rounds, including targeted changes to the terms concerning offshore wind and floating wind projects.
These two paragraphs add more details.
The consultation, published by the Department for Energy Security and Net Zero, seeks industry feedback on contractual and eligibility adjustments, some of which are intended to reflect the increasing scale and complexity of offshore wind developments, specifically floating and other deepwater projects.
For floating offshore wind, the government is proposing changes to CfD contract terms to better align with the technology’s development timelines. These include a proposed extension of the Longstop Period to give floating wind projects more time to commission and avoid termination of their CfD contract.
The government also wants to lower the Required Installed Capacity (RIC) threshold for floating offshore wind projects.
Currently, all CfD technologies are required to deliver a minimum of 95 per cent of the capacity they have contractually agreed to install, except for (fixed-bottom) offshore wind, whose RIC is set at 85 per cent to reflect the construction risks, such as encountering unsuitable seabed conditions after work has commenced. As floating wind projects, which were so far in the range of 100 MW, have grown in scale and complexity, the government plans to apply the same RIC requirement as for fixed-bottom offshore wind.
The CfD scheme currently supports two categories of offshore wind technology: fixed-bottom offshore wind and floating offshore wind, with the regulations in use (Allocation Regulations 2014) considering only the foundation designs that float to be floating offshore wind. With the ODOW category, the government wants to make room for the novel hybrid foundation designs, “which may be suitable for deepwater deployment but do not technically float and would therefore not be considered eligible as ‘floating foundations’ under the existing legal definition of ‘floating offshore wind’.”
This last paragraph sums up the reasons for the changes.
The proposed refinements are intended to ensure the CfD scheme remains fit for purpose as offshore wind technologies evolve, while maintaining investor confidence and supporting timely project delivery.
Hopefully developments at ports like Belfast, East Anglia, Inverness & Cromarty FreePort,Lowestoft and Tyne will encourage to develop wind farms around the shores of the UK.
ABP’s New Lowestoft Facility To Support East Anglia Two & Three O&M Ops
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
UK port operator Associated British Ports (ABP) and ScottishPower Renewables have entered into a long-term agreement for supporting operations and maintenance (O&M) activities at the East Anglia Two and East Anglia Three offshore wind farms from ABP’s Lowestoft Eastern Energy Facility (LEEF).
These two initial paragraphs add a few more details.
Under the agreement, ScottishPower Renewables will utilise berths at LEEF for service operations vessels (SOVs) and crew transfer vessels (CTVs) that will serve the East Anglian offshore wind farms. The company already operates its East Anglia One O&M base in Lowestoft.
LEEF was officially opened by the UK Secretary of State for Energy Security and Net Zero in January 2025, after ABP invested GBP 35 million (almost EUR 40 million) in the port infrastructure. The facility features deep-water berths, modern utilities and future-proofed infrastructure to support shore power and alternative fuels, according to the port operator.
These are some of my thoughts
How Large Are The East Anglian Wind Farms?
There are four East Anglian Wind Farms.
- East Anglian 1 – 714 MW, which was commissioned in 2020.
- East Anglian 1 North – 800 MW, which is planned to be commissioned in 2026.
- East Anglian 2 – 963 MW, which is planned to be commission in 2029.
- East Anglian 3 -1372 MW, which is planned to be commission in 2026.
That makes a total of 3849 MW.
Where Do The Cables Come Ashore?
Google AI gives this answer to the question.
The subsea export cables for the East Anglia wind farms, including East Anglia ONE, come ashore at Bawdsey in Suffolk, where they connect to onshore cables that run underground for about 23-37 km to the Bramford converter station, near Ipswich, to join the National Grid.
I know Bawdsey well from about the late 1950s until we moved my wife and I moved our family from East Suffolk to West Suffolk in the 1990s.
These posts are two memories of Bawdsey Manor and Felixstowe Ferry on the other side of Deben, that I wrote after one of my last visits to the Deben Estuary in 2009.
It hasn’t changed much over the years.
Centrica Really Can’t Lose At Sizewell
The title of this post, is the same as that of this article in The Times.
This is the sub-heading.
Centrica’s £1.3 billion investment in Sizewell C guarantees substantial returns, even with cost overruns.
These two-and-a-half paragraphs explain the funding.
Now we know what Ed Miliband means by his “golden age of nuclear” — golden for the companies putting their money into Sizewell C. Yes, reactor projects have a habit of blowing up private investors. But maybe not this one. It looks more like an exercise in transferring risk to consumers and the taxpayer.
Sure, nobody builds a £38 billion nuke on a Suffolk flood plain without a frisson of danger. But the energy secretary and his Treasury chums have done their bit to make things as safe as possible for the companies putting in equity alongside the government’s 44.9 per cent stake: Canada’s La Caisse with 20 per cent, British Gas-owner Centrica (15 per cent), France’s EDF (12.5 per cent) and Amber Infrastructure (7.6 per cent).
For starters, nearly all the debt for the 3.2 gigawatt plant, three-quarters funded by loans, is coming from the state-backed National Wealth Fund. It’s bunging in up to £36.6 billion, with £5 billion more guaranteed by a French export credit agency.
It looks to me that between them the British and French governments are providing £41.5 billion of loans to build the £38 billion nuke.
These are my thoughts.
Hydrogen And Sizewell C
This page on the Sizewell C web site is entitled Hydrogen And Sizewell C.
Under a heading of Hydrogen Buses, this is said.
At Sizewell C, we are exploring how we can produce and use hydrogen in several ways. We are working with Wrightbus on a pilot scheme which, if successful, could see thousands of workers transported to and from site on hydrogen double decker buses. You can read more about the pilot scheme in our press release
Firstly, it could help lower emissions during construction of the power station. Secondly, once Sizewell C is operational, we hope to use some of the heat it generates (alongside electricity) to make hydrogen more efficiently.
This would appear to be a more general statement about hydrogen and that the following is planned.
- Hydrogen-powered buses will be used to bring workers to the site. A press release on the Sizewell C web site, talks about up to 150 buses. That would probably be enough buses for all of Suffolk.
- Hydrogen-powered construction equipment will be used in the building of the power station.
- It also talks about using the excess heat from the power station to make hydrogen more efficiently. I talk about this process in Westinghouse And Bloom Energy To Team Up For Pink Hydrogen.
This is a substantial investment in hydrogen.
Centrica And Electricity From Sizewell C
The article in The Times, also says this.
Even so, there’s a fair bit of protection for the likes of Centrica, which has also agreed a 20-year offtake deal for its share of Sizewell’s electricity. The price of that is not yet known.
Nothing is said in the article about the size of Centrica’s electricity offtake.
- If they get 15 % of Sizewell C, that would by 480 MW.
- If they get 15 % of Sizewell B + C, that would by 660 MW.
If they use their share to generate hydrogen, Suffolk would have a massive hydrogen hub.
To power the buses and construction of Sizewell C, Sizewell B could be used to provide electricity to create the hydrogen.
How Would The Hydrogen Be Produced?
Centrica, along with other companies, who include Hyundai and Kia, are backers of a company in Hull called HiiROC, who use a process called Thermal Plasma Electrolysis to generate hydrogen.
On their web site, they have this sub-heading.
A Transformational New Process For Affordable Clean Hydrogen
The web site also describes the process as scalable from small modular units up to industrial scale. It also says this about the costs of the system: As cheap as SMR without needing CCUS; a fraction of the energy/cost of water electrolysis.
If HiiROC have achieved their objective of scalability, then Centrica could grow their electrolyser to meet demand.
How Would The Hydrogen Be Distributed?
Consider.
- Currently, the Sizewell site has both road and rail access.
- I can still see in my mind from the 1960s, ICI’s specialist articulated Foden trucks lined up in the yard at Runcorn, taking on their cargoes of hydrogen for delivery all over the country.
- As that factory is still producing hydrogen and I can’t remember any accidents in the last sixty years, I am fairly sure that a range of suitable hydrogen trucks could be developed to deliver hydrogen by road.
- The road network to the Siewell site is being updated to ensure smooth delivery of workers and materials.
- The rail access to the Sizewell site is also being improved, for the delivery of bulk materials.
I believe there will be no problems delivering hydrogen from the Sizewell site.
I also believe that there could be scope for a special-purpose self-propelled hydrogen tanker train, which could both distribute and supply the hydrogen to the vehicles, locomotives and equipment that will be using it.
Where Will The Hydrogen Be Used?
I have lived a large part of my life in Suffolk and know the county well.
In my childhood, there was quite a lot of heavy industry, but now that has all gone and employment is based on agriculture, the Port of Felixstowe and service industries.
I can see hydrogen being used in the following industries.
Transport
Buses and heavy trucks would be powered by hydrogen.
The ports in the East of England support a large number of heavy trucks.
Large Construction Projects
Sizewell C is not the only large construction project in the East of England, that is aiming to use low-carbon construction involving hydrogen. In Gallagher Group Host Hydrogen Fuel Trial At Hermitage Quarry, I talked about a hydrogen fuel trial for the Lower Thames Crossing, that involved JCB and Ryse Hydrogen.
Hydrogen for the Lower Thames Crossing could be delivered from Sizewell by truck, down the A12.
Rail
We may not ever see hydrogen-powered passenger trains in this country, but I do believe that we could see hydrogen-powered freight locomotives.
Consider.
- The latest electro-diesel Class 99 locomotives from Stadler have a Cummins diesel engine.
- The diesel engine is used, when there is no electrification.
- Cummins have developed the technology, that allows them to convert their latest diesel engines to hydrogen or natural gas power, by changing the cylinder head and the fuel system.
- Access to the Port of Felixstowe and London Gateway needs a locomotive with a self-powered capability for the last few miles of the route.
A Class 99 locomotive converted to hydrogen would be able to run with out emitting any carbon dioxide from Felixstowe or London Gateway to Glasgow or Edinburgh.
Ports
Ports have three main uses for hydrogen.
- To power ground-handing equipment, to create a pollution-free atmosphere for port workers.
- To fuel ships of all sizes from the humblest work-boat to the largest container ships.
- There may need to be fuel for hydrogen-powered rail locomotives in the future.
There are seven ports with excellent road and/or rail connections to the Sizewell site; Felixstowe, Great Yarmouth, Harwich, Ipswich, London Gateway, Lowestoft and Tilbury.
The proposed Freeport East is also developing their own green hydrogen hub, which is described on this page on the Freeport East web site.
Airports
Airports have two main uses for hydrogen.
- To power ground-handing equipment, to create a pollution-free atmosphere for airport workers.
- In the future, there is likely to be hydrogen-powered aircraft.
There are three airports with excellent road and/or rail connections to the Sizewell site; Norwich, Southend and Stansted.
Agriculture And The Rural Economy
Agriculture and the rural economy would be difficult to decarbonise.
Consider.
- Currently, most farms would use diesel power for tractors and agricultural equipment, which is delivered by truck.
- Many rural properties are heated by propane or fuel oil, which is delivered by truck.
- Some high-energy rural businesses like blacksmiths rely on propane, which is delivered by truck.
- Electrification could be possible for some applications, but ploughing the heavy land of Suffolk, with the added weight of a battery on the tractor, would probably be a mathematical impossibility.
- JCB are developing hydrogen-powered construction equipment and already make tractors.
- Hydrogen could be delivered by truck to farms and rural properties.
- Many boilers can be converted from propoane to run on hydrogen.
I feel, that hydrogen could be the ideal fuel to decarbonise agriculture and the rural economy.
I cover this application in detail in Developing A Rural Hydrogen Network.
Exports
Consider.
- Sizewell B and Sizewell C nuclear powerstations have a combined output of 4.4 GW.
- A rough calculation shows that there is a total of 7.2 GW of wind farms planned off the Suffolk coast.
- The East Anglian Array wind farm alone is said in Wikipedia to be planned to expand to 7.2 GW.
- The Sizewell site has a high capacity connection to the National Grid.
Nuclear plus wind should keep the lights on in the East of England.
Any excess electricity could be converted into hydrogen.
This Google Map shows the location of Sizewell B in relation to Belgium, Germany and The Netherlands.
The Sizewell site is indicated by the red arrow.
The offshore oil and gas industry has used technology like single buoy moorings and coastal tankers to collect offshore natural gas for decades.
I don’t see why coastal hydrogen tankers couldn’t export excess hydrogen to places around the North Sea, who need the fuel.
It should be born in mind, that Centrica have a good reputation in doing natural gas trading. This expertise would surely be useful in hydrogen trading.
Conclusion
I believe that a hydrogen hub developed at Sizewell makes sense and I also believe that Centrica have the skills and technology to make it work.
Sizewell C – Where Will The Workers Live?
I have now written about, where the two Park-and-Ride sites are to be built.
- The Northern Park-and-Ride is proposed for Darsham.
- The Southern Park-and-Ride is proposed for Wickham Market.
I can now write about where the workers could be billeted.
I suspect there could be a Bibby Stockholm solution, where accommodation barges are used.
This Google Map shows the centre of Ipswich.
Note.
- There is a lot of space on the River Orwell.
- Ipswich station is in the North-West corner of the map.
- There could be a shuttle bus between the barge and the station.
- Trains could take workers to Darsham for buses to Sizewell.
There could even be direct buses to Sizewell.
This Google Map shows the centre of Lowestoft.
Note.
- The Bibby Stockholm is 100 metres long with a beam of 30 metres.
- Lowestoft station is close to the port.
Workers could take the train direct to the Northern Park-and-Ride for Sizewell C.
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.
Low Carbon Construction Of Sizewell C Nuclear Power Station
Sizewell C Nuclear Power Station is going to be built on the Suffolk Coast.
Wikipedia says this about the power station’s construction.
The project is expected to commence before 2024, with construction taking between nine and twelve years, depending on developments at the Hinkley Point C nuclear power station, which is also being developed by EDF Energy and which shares major similarities with the Sizewell plant.
It is a massive project and I believe the construction program will be designed to be as low-carbon as possible.
High Speed Two is following the low-carbon route and as an example, this news item on their web site, which is entitled HS2 Completes Largest Ever UK Pour Of Carbon-Reducing Concrete On Euston Station Site, makes all the right noises.
These three paragraphs explain in detail what has been done on the Euston station site.
The team constructing HS2’s new Euston station has undertaken the largest ever UK pour of Earth Friendly Concrete (EFC) – a material that reduces the amount of carbon embedded into the concrete, saving over 76 tonnes of CO2 overall. John F Hunt, working for HS2’s station Construction Partner, Mace Dragados joint venture, completed the 232 m3 concrete pour in early September.
The EFC product, supplied by Capital Concrete, has been used as a foundation slab that will support polymer silos used for future piling works at the north of the Euston station site. Whilst the foundation is temporary, it will be in use for two years, and historically would have been constructed with a more traditional cement-based concrete.
The use of the product on this scale is an important step forward in how new, innovative environmentally sustainable products can be used in construction. It also helps support HS2’s objective of net-zero construction by 2035, and achieve its goal of halving the amount of carbon in the construction of Britain’s new high speed rail line.
Note.
- Ten of these slabs would fill an Olympic swimming pool.
- I first wrote about Earth Friendly Concrete (EFC) in this post called Earth Friendly Concrete.
- EFC is an Australian invention and is based on a geopolymer binder that is made from the chemical activation of two recycled industrial wastes; flyash and slag.
- HS2’s objective of net-zero construction by 2035 is laudable.
- It does appear that this is a trial, but as the slab will be removed in two years, they will be able to examine in detail how it performed.
I hope the Sizewell C project team are following High Speed Two’s lead.
Rail Support For Sizewell C
The Sizewell site has a rail connection and it appears that this will be used to bring in construction materials for the project.
In the January 2023 Edition of Modern Railways, there is an article, which is entitled Rail Set To Support Sizewell C Construction.
It details how sidings will be built to support the construction, with up to four trains per day (tpd), but electrification is not mentioned.
This is surprising to me, as increasingly, big construction projects are being managed to emit as small an amount of carbon as possible. Sizewell C may be an isolated site, but in Sizewell B, it’s got one of the UK’s biggest independent carbon-free electricity generators a couple of hundred metres away.
The writer of the Modern Railways article, thinks an opportunity is being missed.
I feel the following should be done.
- Improve and electrify the East Suffolk Line between Ipswich and Saxmundham Junction.
- Electrify the Aldeburgh Branch Line and the sidings to support the construction or agree to use battery-electric or hydrogen zero-carbon locomotives.
Sizewell C could be a superb demonstration project for low-carbon construction!
Sizewell C Deliveries
Sizewell C will be a massive project and and will require a large number of deliveries, many of which will be heavy.
The roads in the area are congested, so I suspect rail is the preferred method for deliveries.
We already know from the Modern Railways article, that four tpd will shuttle material to a number of sidings close to the site. This is a good start.
Since Sizewell A opened, trains have regularly served the Sizewell site to bring in and take out nuclear material. These occasional trains go via Ipswich and in the last couple of years have generally been hauled by Class 88 electro-diesel locomotives.
It would be reasonable to assume that the Sizewell C sidings will be served in the same manner.
But the route between Westerfield Junction and Ipswich station is becoming increasingly busy with the following services.
- Greater Anglia’s London and Norwich services
- Greater Anglia’s Ipswich and Cambridge services
- Greater Anglia’s Ipswich and Felixstowe services
- Greater Anglia’s Ipswich and Lowestoft services
- Greater Anglia’s Ipswich and Peterborough services
- Freight services serving the Port of Felixstowe, which are expected to increase significantly in forthcoming years.
But the Modern Railways article says this about Saxmundham junction.
Saxmundham junction, where the branch meets the main line, will be relaid on a slightly revised alignment, retaining the existing layout but with full signalling giving three routes from the junction protecting signal on the Down East Suffolk line and two in the Down direction on the bidirectional Up East Suffolk line. Trap points will be installed on the branch to protect the main line, with the exit signal having routes to both running lines.
Does the comprehensive signalling mean that a freight train can enter or leave the Sizewell sidings to or from either the busy Ipswich or the quieter Lowestoft direction in a very safe manner?
I’m no expert on signalling, but I think it does.
- A train coming from the Lowestoft direction needing to enter the sidings would go past Saxmundham junction on the Up line. Once clear of the junction, it would stop and reverse into the branch.
- A train coming from the Ipswich direction needing to enter the sidings would approach in the wrong direction on the Up line and go straight into the branch.
- A train leaving the sidings in the Lowestoft direction would exit from the branch and take the Up line until it became single track. The train would then stop and reverse on to the Down line and take this all the way to Lowestoft.
- A train leaving the sidings in the Ipswich direction would exit from the branch and take the Up line all the way to Ipswich.
There would need to be ability to move the locomotive from one end to the other inside the Sizewell site or perhaps these trains could be run with a locomotive on both ends.
The advantage of being able to run freight trains between Sizewell and Lowestoft becomes obvious, when you look at this Google Map, which shows the Port of Lowestoft.
Note.
- The Inner Harbour of the Port of Lowestoft.
- The East Suffolk Line running East-West to the North of the Inner Harbour.
- Lowestoft station at the East side of the map.
I doubt it would be the most difficult or expensive of projects to build a small freight terminal on the North side of the Inner Harbour.
I suspect that the easiest way to bring the material needed to build the power station to Sizewell would be to do the following.
- Deliver it to the Port of Lowestoft by ship.
- Tranship to a suitable shuttle train for the journey to the Sizewell sidings.
- I estimate that the distance is only about 25 miles and a battery or hydrogen locomotive will surely be available in the UK in the next few years, that will be able to provide the motive power for the return journey.
In The TruckTrain, I wrote about a revolutionary freight concept, that could be ideal for the Sizewell freight shuttle.
In addition, there is no reason, why shuttle trains couldn’t come in from anywhere connected to the East Suffolk Line.
Zero-Carbon Construction
Sizewell C could be the first major construction site in the UK to use electricity rather than diesel simply because of its neighbour.
Conclusion
I shall be following the construction methods at Sizewell C, as I’m fairly sure they will break new ground in the decarbonisation of the Construction industry.
Could Greater Anglia Run A Comprehensive Service For East Anglia?
Consider.
- In the last fifty years, there have been direct trains between London Liverpool Street and Lowestoft stations.
- In the last forty years, there have been direct trains between London Liverpool Street and Peterborough stations.
- Greater Anglia currently run an hourly train between London Liverpool Street and Ipswich stations, with stops at Stratford, Shenfield, Chelmsford, Hatfield Peverel, Witham, Kelvedon, Marks Tey, Colchester and Manningtree
- Frequencies on both routes were not high and less than four trains per day (tpd), but they must have been a demand for these services.
- Greater Anglia promised to run a Lowestoft service, when they successfully reapplied for the franchise.
- Greater Anglia have 38 Class 755 trains, of which 14 are three-cars and 24 are four-cars.
- Class 755 trains can run in twoses and possibly threeses. (Suffolk dialect for twins and triplets!)
Could these elements be assembled to provide a comprehensive East Anglia service?
- A pair of Class 755 trains would leave Liverpool Street for Ipswich.
- They would takeover some of the paths of the hourly Liverpool Street and Ipswich service and run possibly about four or five tpd, according to demand.
- Between Liverpool Street and Ipswich the trains could stop at Stratford, Shenfield, Chelmsford, Hatfield Peverel, Witham, Kelvedon, Marks Tey, Colchester and Manningtree
- The services would splitgoing North and join going South at Ipswich
- One train would go to Peterborough with stops at Needham Market, Stowmarket, Elmswell, Thurston, Bury St. Edmunds, Soham, Ely, Manea, March and Whittlesea.
- The other would go to Lowestoft with stops at Woodbridge, Melton, Wickham Market, Saxmundham, Darsham, Halesworth, Brampton, Beccles and Oulton Broad South.
Note.
- The Class 755 trains would use electricity, where electrification exists.
- They would use diesel on lines without electrification.
- They would be able to hold 100 mph, so wouldn’t delay other trains.
- Seventeen towns would get new direct services to and from London.
- A Class 745 train is 236.6 metres long, whereas a pair of four-car Class 755 trains is only 161.4 metres.
- A three-train formation of Class 755 trains is only 5.5 metres longer than a single Class 745 train.
I am fairly sure no new substantial infrastructure would be required.
I have some further thoughts.
Example Timings
These timings to and from London are based on current timings of the Class 745 and 755 trains.
- Ipswich – 60 mins
- Stowmarket -70 mins
- Bury St. Edmunds – 88 mins
- Soham – 108 mins
- Ely – 117 mins
- March – 136 mins
- Peterborough – 158 mins
- Woodbridge – 75 mins
- Melton – 80 mins
- Wickham Market – 86 mins
- Saxmundham – 97 mins
- Darsham – 104 mins
- Halesworth – 113 mins
- Brampton – 119 mins
- Beccles – 128 mins
- Oulton Broad South – 138 mins
- Lowestoft – 146 mins
Notes.
- Times to and from Ipswich are based on typical services at the current time.
- I have assumed that there are no stops South of Ipswich.
- Saxmundham is the closest station to Sizewell and could be important in bringing in construction workers for Sizewell C.
I think some of the times like those to and from Bury St. Edmunds, Ipswich, Lowestoft, Saxmundham and Woodbridge could create popular routes.
Battery-Electric Trains
Consider.
- I wrote about Stadler’s expertise with battery-electric trains in Stadler FLIRT Akku Battery Train Demonstrates 185km Range.
- 185 km. is 115 miles.
- The Class 756 trains for Transport for Wales are similar trains to the Class 755 trains fitted with batteries.
- In Battery Power Lined Up For ‘755s’, I wrote about plans to put batteries in the Class 755 trains.
These sections of lines are not electrified on the routes I have talked about.
- Haughley Junction and Ely – 38 miles
- Ely and Peterborough – 30.5 miles
- Westerfield and Lowestoft – 38 miles
As there is electrification at Ely, Haughley, Peterborough and Westerfield and South to London, I am fairly certain the route could be run by battery-electric trains.
Electrification To Sizewell C
In the January 2023 Edition of Modern Railways, there is an article, which is entitled Rail Set To Support Sizewell C Construction.
It details how sidings will be built to support the construction, with up to four trains per day (tpd), but the electrification word is not mentioned.
This is surprising to me, as increasingly, big construction projects are being managed to emit as small an amount of carbon as possible. High Speed Two is being built this way and I suspect Rolls-Royce’s SMR design will minimise carbon emissions during manufacture and construction. It will be very surprising if Sizewell C doesn’t follow High Speed Two’s example. After all, it may be an isolated site, but in Sizewell B, it’s got one of the UK’s biggest carbon-free electricity generators a couple of hundred metres away.
The writer of the Modern Railways article, thinks an opportunity is being missed.
I feel the following should be done.
- Improve and electrify the East Suffolk Line between Ipswich and Saxmundham Junction.
- Electrify the Aldeburgh Branch Line and the sidings to support the construction or agree to use battery-electric or hydrogen zero-carbon locomotives.
One of the collateral benefits of electrifying from Ipswich to Saxmundham Junction, is that it will make it easier for battery-electric Class 755 trains to work Ipswich and Lowestoft services.
- If the trains were to leave Saxmundham Junction going North with a full battery, they should be able to travel to Lowestoft and return.
- Battery-electric Class 755 trains could bring in workers from Ipswich or Lowestoft and further afield.
- It could even leave behind a zero-carbon branch line to Sizewell, Leiston and Aldeburgh, with two tph to Ipswich.
Sizewell C could be a superb demonstration project for low-carbon construction!
The Lowestoft-Great Yarmouth Conurbation
The Wikipedia entry for Lowestoft says this about the town.
The estimated population in the built-up area exceeds 70,000. Its development grew with the fishing industry and as a seaside resort with wide sandy beaches. As fishing declined, oil and gas exploitation in the North Sea in the 1960s took over. While these too have declined, Lowestoft is becoming a regional centre of the renewable energy industry.
Whilst the Wikipedia entry for Great Yarmouth says this about the town.
Great Yarmouth, often called Yarmouth, is a seaside town and unparished area in, and the main administrative centre of, the Borough of Great Yarmouth in Norfolk, England; it straddles the River Yare and is located 20 miles (30 km) east of Norwich. A population of 38,693 in the 2011 Census made it Norfolk’s third most populous. Its fishing industry, mainly for herring, shrank after the mid-20th century and has all but ended.[3] North Sea oil from the 1960s supplied an oil-rig industry that services offshore natural gas rigs; more recently, offshore wind power and other renewable energy industries have ensued.
Wikipedia also said this about the population of the wider Great Yarmouth.
The wider Great Yarmouth borough had a population of around 92,500, which increased to 97,277 at the 2011 census.
Taken together they are one of the largest conurbations in East Anglia.
The main means of transport between the two towns is by road.
Surely, two towns of over 70,000 people, who are only a few miles apart need a rail connection.
Onward From Lowestoft To Great Yarmouth
If the comprehensive East Anglia service, I’m discussing is to be truly comprehensive, it must serve the Norfolk Broads and Great Yarmouth.
This would also improve the connectivity between two of the largest coastal towns in East Anglia, that I indicated in the last section.
This OpenRailwayMap shows a cunning plan proposed by Network Rail to connect Lowestoft and Great Yarmouth.
Note.
- Great Yarmouth is in the North East corner of the map.
- Two lines lead West from Great Yarmouth station, with the more Northerly route going direct to Norwich and the more Southerly one going to Norwich via Berney Arms and Reedham.
- Lowestoft is in the South East corner of the map.
- Two lines lead West from Lowestoft station, with the Northern route going to Norwich via Reedham and the Southern one going to Ipswich via Oulton Broad South.
- The route of a coastal railway connecting the two towns is also shown.
Network Rail’s cunning plan is indicated on this second nap from OpenRailwayMap.
Note.
- Reedham station is in the North-West corner of the map on the line to Norwich.
- To the East of the station is a triangular junction.
- The track from the North-East corner of the junction is the line to Great Yarmouth.
- The track from the Southern corner of the junction is the line to Lowestoft.
- Unfortunately, the South-Eastern leg of the junction was removed in 1880.
In Norfolk Rail Line To Remain Closed As £68m Upgrade Project Overruns, I said this.
Network Rail are talking about reinstating the Reedham Chord to create a more direct route between East Anglia’s largest North-Eastern towns. This is said about the Reedham Chord in Direct Yarmouth Services in the Wikipedia entry for Lowestoft station.
In January 2015, a Network Rail study proposed the reintroduction of direct services between Lowestoft and Yarmouth by reinstating a spur at Reedham. Services could once again travel between two East Coast towns, with an estimated journey time of 33 minutes, via a reconstructed 34-chain (680 m) north-to-south arm of the former triangular junction at Reedham, which had been removed in c. 1880. The plans also involve relocating Reedham station nearer the junction, an idea which attracted criticism.
This sounds a good plan to me.
- It would allow direct services between Lowestoft and Great Yarmouth.
- It would allow direct services between Ipswich and Great Yarmouth with a reverse at Lowestoft in about two hours.
- With possible charging at Lowestoft and/or Great Yarmouth, a scenic route could be created between Ipswich and Norwich for battery-electric Class 755 trains. If that doesn’t get people out of their cars then nothing will!
- Various leisure, tourism and work-related opportunities would be created.
Never in the field of railway engineering would such a small chord have given so much.
Sizewell C Issues
Sizewell C will be a massive project and I also suspect that like High Speed Two, it will be built in a manner that will be zero-carbon where possible.
We already know from the Modern Railways article, that four tpd will shuttle material to a number of sidings close to the site. This is a good start.
Since Sizewell A opened, trains have regularly served the Sizewell site to bring in and take out nuclear material. These occasional trains go via Ipswich and in the last couple of years have generally been hauled by Class 88 electro-diesel locomotives.
It would be reasonable to assume that the Sizewell C sidings will be served in the same manner.
But the route between Westerfield Junction and Ipswich station is becoming increasingly busy with the following services.
- Greater Anglia’s London and Norwich services
- Greater Anglia’s Ipswich and Cambridge services
- Greater Anglia’s Ipswich and Felixstowe services
- Greater Anglia’s Ipswich and Lowestoft services
- Greater Anglia’s Ipswich and Peterborough services
- Freight services serving the Port of Felixstowe, which are expected to increase significantly in forthcoming years.
But the Modern Railways article says this about Saxmundham junction.
Saxmundham junction, where the branch meets the main line, will be relaid on a slightly revised alignment, retaining the existing layout but with full signalling giving three routes from the junction protecting signal on the Down East Suffolk line and two in the Down direction on the bidirectional Up East Suffolk line. Trap points will be installed on the branch to protect the main line, with the exit signal having routes to both running lines.
Does the comprehensive signalling mean that a freight train can enter or leave the Sizewell sidings to or from either the busy Ipswich or the quieter Lowestoft direction in a very safe manner?
I’m no expert on signalling, but I think it does.
- A train coming from the Lowestoft direction needing to enter the sidings would go past Saxmundham junction on the Up line. Once clear of the junction, it would stop and reverse into the branch.
- A train coming from the Ipswich direction needing to enter the sidings would approach in the wrong direction on the Up line and go straight into the branch.
- A train leaving the sidings in the Lowestoft direction would exit from the branch and take the Up line until it became single track. The train would then stop and reverse on to the Down line and take this all the way to Lowestoft.
- A train leaving the sidings in the Ipswich direction would exit from the branch and take the Up line all the way to Ipswich.
There would need to be ability to move the locomotive from one end to the other inside the Sizewell site or perhaps these trains could be run with a locomotive on both ends.
The advantage of being able to run freight trains between Sizewell and Lowestoft becomes obvious, when you look at this Google Map, which shows the Port of Lowestoft.
Note.
- The Inner Harbour of the Port of Lowestoft.
- The East Suffolk Line running East-West to the North of the Inner Harbour.
- Lowestoft station at the East side of the map.
I doubt it would be the most difficult or expensive of projects to build a small freight terminal on the North side of the Inner Harbour.
I suspect that the easiest way to bring the material needed to build the power station to Sizewell would be to do the following.
- Deliver it to the Port of Lowestoft by ship.
- Tranship to a suitable shuttle train for the journey to the Sizewell sidings.
- I estimate that the distance is only about 25 miles and a battery or hydrogen locomotive will surely be available in the UK in the next few years, that will be able to provide the motive power for the return journey.
In The TruckTrain, I wrote about a revolutionary freight concept, that could be ideal for the Sizewell freight shuttle.
Great Yarmouth Racecourse
Great Yarmouth Racecourse is one of my favourite racecourses and I believe it is one of the attractions in Great Yarmouth, that would benefit from an improved rail service between Lowestoft and Great Yarmouth, as it would almost double those with efficient public transport access to the racecourse.
The walking distance between Great Yarmouth station and the racecourse is walkable for many and I remember doing it since C died.
With the train connection to Lowestoft and perhaps a courtesy bus from the station, I wouldn’t be surprised to see that a Lowestoft-Yarmouth rail connection being very good for the racecourse. Especially as road traffic between the two towns can be not the best.
Finishing At Norwich
There are operational reasons to carry on to Norwich, where Crown Point, is the home base for the Class 755 trains.
But it would also link a lot of places that are dependant on tourism and are also heavily involved in East Anglia’s energy industry.
Onward From Peterborough To Lincoln
If the Lowestoft service can extend to Great Yarmouth, an extension of the Peterborough service to Lincoln via Spalding and Sleaford might be possible.
But with LNER also serving Lincoln from Kings Cross, I doubt the route would carry many passengers to and from London.
Conclusion
A service from London, that splits into two trains at Ipswich for Lowestoft and Peterborough has possibilities.
