RWE And the Norfolk Wind Farms
In March 2024, I wrote RWE And Vattenfall Complete Multi-Gigawatt Offshore Wind Transaction In UK, which described how Vattenfall had sold 4.2 GW of offshore wind farms, situated off North-East Norfolk to RWE.
This map from RWE shows the wind farms.
Note.
- The Norfolk Zone consists of three wind farms; Norfolk Vanguard West, Norfolk Boreas and Norfolk Vanguard East.
- The three wind farms are 1.4 GW fixed-foundation wind farms.
- In Vattenfall Selects Norfolk Offshore Wind Zone O&M Base, I describe how the Port of Great Yarmouth had been selected as the O & M base.
- Great Yarmouth and nearby Lowestoft are both ports, with a long history of supporting shipbuilding and offshore engineering.
The wind farms and the operational port are all close together, which probably makes things convenient.
So why did Vattenfall sell the development rights of the three wind farms to RWE?
Too Much Wind?
East Anglia is fringed with wind farms all the way between the Wash and the Thames Estuary.
- Lincs – 270 MW
- Lynn and Inner Dowsing – 194 MW
- Race Bank – 580 MW
- Triton Knoll – 857 MW
- Sheringham Shoal – 317 MW
- Dudgeon – 402 MW
- Hornsea 3 – 2852 MW *
- Scroby Sands – 60 MW
- East Anglia One North – 800 MW *
- East Anglia Two – 900 MW *
- East Anglia Three – 1372 MW *
- Greater Gabbard – 504 MW
- Galloper – 353 MW
- Five Estuaries – 353 MW *
- North Falls – 504 MW *
- Gunfleet Sands – 172 MW
- London Array – 630 MW
Note.
- Wind farms marked with an * are under development or under construction.
- There is 4339 MW of operational wind farms between the Wash and the Thames Estuary.
- An extra 6781 MW is also under development.
If all goes well, East Anglia will have over 11 GW of operational wind farms or over 15 GW, if the three Norfolk wind farms are built.
East Anglia is noted more for its agriculture and not for its heavy industries consuming large amounts of electricity, so did Vattenfall decide, that there would be difficulties selling the electricity?
East Anglia’s Nimbies
East Anglia’s Nimbies seem to have started a campaign against new overground cables and all these new wind farms will need a large capacity increase between the main substations of the National Grid and the coast.
So did the extra costs of burying the cable make Vattenfall think twice about developing these wind farms?
East Anglia and Kent’s Interconnectors
East Anglia and Kent already has several interconnectors to Europe
- Viking Link – Bicker Fen and Jutland – 1.4 GW
- LionLink – Suffolk and the Netherlands – 1.8 GW – In Planning
- Nautilus – Suffolk or Isle of Grain and Belgium – 1.4 GW – In Planning
- BritNed – Isle of Grain and Maasvlakte – 1.0 GW
- NeuConnect – Isle of Grain and Wilhelmshaven – 1.4 GW – Under Construction
- GridLink Interconnector – Kingsnorth and Warande – 1.4 GW – Proposed
- HVDC Cross-Channel – Sellinge and Bonningues-lès-Calais – 2.0 GW
- ElecLink – Folkestone and Peuplingues – 1.0 GW
- Nemo Link – Richborough and Zeebrugge – 1.0 GW
Note.
- Five interconnectors with a capacity of 6.4 GW.
- A further four interconnectors with a capacity of 6 GW are on their way.
At 12.4 GW, the future capacity of the interconnectors between South-East England and Europe, is nor far short of South-East English wind power.
There are also two gas pipelines from the Bacton gas terminal between Cromer and Great Yarmouth to Europe.
The Wikipedia entry for the Bacton gas terminal gives these descriptions of the two gas pipelines.
Interconnector UK – This can import gas from, or export gas to, Zeebrugge, Belgium via a 235 km pipeline operating at up to 147 bar. There is a 30-inch direct access line from the SEAL pipeline. The Interconnector was commissioned in 1998.
BBL (Bacton–Balgzand line) – This receives gas from the compressor station in Anna Paulowna in the Netherlands. The BBL Pipeline is 235 km long and was commissioned in December 2006.
It would appear that East Anglia and Kent are well connected to the Benelux countries, with both electricity and gas links, but with the exception of the Viking Link, there is no connection to the Scandinavian countries.
Did this lack of connection to Sweden make convincing the Swedish government, reluctant to support Vattenfall in their plans?
Bringing The Energy From The Norfolk Wind Farms To Market
It looks to me, that distributing up to 4.2 GW from the Norfolk wind farms will not be a simple exercise.
- Other wind farms like the 2852 MW Hornsea 3 wind farm, may need a grid connection on the North Norfolk coast.
- The Nimbies will not like a South-Western route to the National Grid at the West of Norwich.
- An interconnector to Denmark or Germany from North Norfolk would probably help.
But at least there are two gas pipelines to Belgium and the Netherlands.
RWE, who now own the rights to the Norfolk wind farms, have a large amount of interests in the UK.
- RWE are the largest power producer in the UK.
- They supply 15 % of UK electricity.
- They have interest in twelve offshore wind farms in the UK. When fully-developed, they will have a capacity of almost 12 GW.
- RWE are developing the Pembroke Net Zero Centre, which includes a hydrogen electrolyser.
RWE expects to invest up to £15 billion in the UK by 2030 in new and existing green technologies and infrastructure as part of this.
Could this be RWE’s plan?
As the Norfolk wind farms are badly placed to provide electricity to the UK grid could RWE have decided to use the three Norfolk wind farms to produce hydrogen instead.
- The electrolyser could be placed onshore or offshore.
- If placed onshore, it could be placed near to the Bacton gas terminal.
- There are even depleted gas fields, where hydrogen could be stored.
How will the hydrogen be distributed and/or used?
It could be delivered by tanker ship or tanker truck to anyone who needs it.
In Developing A Rural Hydrogen Network, I describe how a rural hydrogen network could be developed, that decarbonises the countryside.
There are three major gas pipelines leading away from the Bacton gas terminal.
- The connection to the UK gas network.
- Interconnector UK to Belgium.
- BBL to The Netherlands.
These pipelines could be used to distribute hydrogen as a hydrogen blend with natural gas.
In UK – Hydrogen To Be Added To Britain’s Gas Supply By 2025, I describe the effects of adding hydrogen to the UK’s natural gas network.
Gresham House BESS Fund Energises 50MWh Asset
The title of this post, is the same as that of this article on Solar Power Portal.
These three paragraphs detail the project.
Gresham House Energy Storage Fund has energised a 50MW/50MWh battery energy storage system (BESS) in Lancashire.
Situated in Penwortham, south-west of the county capital Preston, the 1-hour duration BESS is set to be expanded to 2-hours in the summer, meaning its capacity would be 50MW/100MWh.
With the commencement of this new BESS, Gresham House Energy Storage Fund’s operational capacity has now reached 790MW/926MWh. The project is the fund’s 25th operational asset since IPO.
Note.
- The battery will be upgraded to a two-hour battery in the summer.
- The average battery would appear to be 32 MW/37 MWh.
- The average full-power duration for all Gresham House’s batteries appears to be around 70 minutes.
This Google Map shows the battery, which is located next to National Grid’s Penwortham substation.
Note.
- The battery is the two rows of green containers at the top of the map.
- The substation appears to be large.
Co-location like this, must surely bring design, construction and operational advantages.
This page on the National Grid web site is entitled Network And Infrastructure, where this is said.
We own the national electricity transmission system in England and Wales. The system consists of approximately 4,500 miles of overhead line, over 900 miles of underground cable and over 300 substations.
If every substation in the UK were to be fitted with a 32 MW/64 MWh two hour battery, these would have a total capacity of 9.6 GW/19.2 GWh.
Compare that with these operational batteries and pumped-storage systems in the UK.
- Cruachan – 1000 MW/7.1 GWh – Pumped Storage
- Dinorwig – 1800 MW/9.1 GWh – Pumped Storage
- Ffestiniog – 360 MW/1.44 GWh – Pumped Storage
- Minety -150 MW/266 MWh – BESS
- Pillswood – 98 MW/196 MWh – BESS
And these systems are under development
- Coire Glas – 1.5GW/30 GWh – Pumped Storage
- Loch Na Cathrach/Red John – 450 MW/2.8 GWh – Pumped Storage
- London Gateway – 320 MW/640 MWh – BESS
There are at least another four substantial pumped storage systems under development.
Conclusion
A twin-track approach of grid-batteries at sub-stations and a few larger grid batteries and pumped storage hydroelectric schemes should be able to provide enough storage.
Ørsted, Simply Blue, Subsea7 Submit Application For 100 MW Scottish Floating Wind Farm
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Ørsted, Simply Blue Group and Subsea7, through their joint venture partnership in Scotland, have submitted an offshore consent application for the proposed 100 MW Salamander floating offshore wind farm, one of the 13 projects selected in Scotland’s Innovation and Targeted Oil and Gas (INTOG) leasing round.
The article starts with a map that shows the location of the Salamander floating offshore wind farm and it shows how the sea is getting very crowded 35 kilometres off Peterhead.
This map shows the various ScotWind leases, around the North of Scotland.
The numbers are Scotwind’s lease number in their documents.
These are the Scotwind wind farms to the North-East of Scotland.
- 1 – BP Alternative Energy Investments – 859 km² – 2.9 GW – Fixed
- 2 – SSE Renewables – 859 km² – 2.6 GW – Floating
- 3 – Falck Renewables Wind – 280 km² – 1.2 GW – Floating
- 4 – Shell – 860 km² – 2.0 GW – Floating
- 5 – Vattenfall – 200 km² – 0.8 GW – Floating
- 6 – DEME – 187 km² – 1.0 GW – Fixed
- 9 – Ocean Winds – 429 km² – 1.0 GW – Fixed
- 10 – Falck Renewables Wind – 134 km² – 0.5 GW – Floating
- 11 – Scottish Power Renewables – 684 km² – 3.0 GW – Floating
- 12 – BayWa r.e. UK – 330 km² – 1.0 GW – Floating
Note.
- Salamander is located to the South of wind farms 10, 11 and 12 and to the North-West of wind farm 5.
- These windfarms total up to 16 GW.
- 4.9 GW are fixed foundation wind farms.
- 11.1 GW are floating wind farms.
These are my thoughts.
The Salamander Project
In the big scheme of things, the 100 MW Salamander wind farm, is rather a tiddler of a wind farm.
On the Salamander wind farm web site, a section gives the Project Goals.
- Our innovative pre-commercial stepping-stone concept will use novel floating foundations to (i) maximise Scottish content, (ii) enable the Scottish supply chain to gear up for the future floating offshore wind commercial opportunities in ScotWind and (iii) reduce the financial, environmental and technology risks of floating offshore wind.
- The Salamander project will contribute to the Scottish Government and UK Government net-zero targets. The project can contribute to the Scottish government’s target of 11 GW of installed offshore wind by 2030, as well as the UK government’s target of 5 GW of operational floating offshore wind by the same date.
- We are dedicated to developing a sustainable and transformative project, working with the oceans, and enabling communities to benefit from Project Salamander. Therefore, we commit to having a continuous and strong stakeholder and community engagement.
It appears to me, that the Salamander project will be a pathfinder for the 11.1 GW of floating wind farms to be built off Peterhead.
Bringing The Electricity South
National Grid are building four interconnectors between Eastern Scotland and Eastern England.
- Eastern Green Link 1 – Torness and Hawthorn Pit
- Eastern Green Link 2 – Peterhead and Drax
- Eastern Green Link 3 – Westfield and Lincolnshire
- Eastern Green Link 4 – Peterhead and Lincolnshire
Note.
- All interconnectors are 2 GW.
- All interconnectors are offshore for a long part of their route.
- It also appears that National Grid are burying much of the onshore sections.
But the 4 GW of interconnectors will only be able to bring a quarter of the offshore electricity generated in the Peterhead area to the South.
What Will Happen To The Excess Electricity?
Consider.
- There could be 16 GW of planned offshore wind power around Peterhead and North-East Scotland.
- There is only 4 GW of interconnector capacity between Peterhead and Eastern England.
- There is another 6.8 GW of electricity around North-West Scotland.
- There is 2.8 GW of electricity being developed to the East of Shetland.
- The Crown Estate is thinking of increasing the size of some offshore wind farms.
It is likely, that other wind farms will be built in the seas around the North of Scotland.
It appears that the North of Scotland could have at least 20 GW of excess electricity.
Possible solutions would include.
- Developing energy intensive industries like metal refining.
- More interconnectors to Denmark, England, Ireland and Norway.
- Storage of the electricity in giant pumped storage hydroelectric power stations.
- Creation of green hydrogen for export.
Note.
- Aluminium refining has been developed in the North of Scotland before.
- More interconnectors are a possibility, especially as Scotland is developing cable manufacturing capacity.
- Some maps show extra interconnectors between West Scotland and Merseyside.
- At least 70 GWh of pumped storage hydroelectric power stations are being developed along the Great Glen.
- I suspect that the pumped storage hydroelectric power stations could be connected to the wind farms, by cables under the waters of Loch Ness.
But surely, production of green hydrogen for export would be a very good way to go.
- Extra electrolysers could be added as required.
- Because of the interconnectors down both East and West Coasts, electrolysers could be built in England, where there is a large need for hydrogen.
- Hydrogen would be exported initially by tanker ships.
- At some point in the future, it might be viable to build a hydrogen pipeline to connect to the growing European hydrogen network.
The giant pumped storage hydroelectric power stations and the hydrogen electrolysers would be sized to make sure, that no wind power is never wasted.
Conclusion
The 100 MW Salamander floating wind farm may only be small, but it will prove the technology, the manufacturing and the supply chains, so that Scotland can have a second energy boom from the North Sea.
But this boom will certainly last longer than a hundred years.
Europe’s Mines Look To Gravity Energy Storage For Green Future
The title of this post, is the same as that of this article on Global Mining Review.
This is the sub-heading.
Mine owners across Europe are looking at a new form of underground energy storage to offer a low carbon future as operations wind down.
These are the first four paragraphs.
Active deep mine operators in Slovenia, Germany, The Czech Republic and Finland are all examining how underground gravity energy storage – provided by Edinburgh firm Gravitricity – could offer green opportunities to mining communities facing a downturn in employment.
Gravitricity has developed a unique energy storage system, known as GraviStore, which uses heavy weights – totalling up to 12 000 t – suspended in a deep shaft by cables attached to winches.
This offers a viable alternative future to end of life mine shafts, which otherwise face costly infilling and mine decommissioning costs.
They have teamed up with energy multinational and winch specialist ABB alongside worldwide lifting specialists Huisman to commercialise the technology for mine operators.
Note.
- Four projects are mentioned.
- It appears to be less costly, than infilling.
- Gravitricity have teamed with ABB and Huisman, who are two of Europe’s specialist in this field.
- You can’t have too much energy storage.
The article is worth a full read.
Conclusion
Gravitricity’s simple idea could be a big winner.
Aura Power Secures £10 Million Funding From Novuna
The title of this post, is the same as that of this article on Solar Power Portal.
These two paragraphs introduce the deal.
Aura Power has announced the successful closing of a £10 million debt facility with Novuna Business Finance. Novuna is a part of Mitsubishi HC Capital UK PLC, designed to support projects from early development through to the operational phase.
Bristol-based Aura Power is developing an active pipeline of utility-scale solar PV and battery energy storage of about 12GW in the UK, Europe and North America. The funding will help progress global development for Aura, covering expenditures like grid payments, planning fees and legal land costs.
These two paragraphs describe some of Aura’s projects.
In December 2023, Aura was granted planning permission for a 100MW/400MWh battery energy storage (BESS) project in Capenhurst, Cheshire. It was the third UK project to receive planning permission last year, alongside Aura’s 49.9MW Horton Solar Farm located in East Devon and its 49.9MW Hawthorn Pit Solar Farm in Durham.
Aura has been active within the solar and battery industries, with a pipeline in development in excess of 20GW. Last week (2 May), following an appeal, the developer secured planning permission for an Essex solar farm that will have an export capacity of 30 MW.
Nearly, forty years ago, I started a finance company in Ipswich with a friend. Our financing was mainly directed towards truck leasing for companies moving containers to and from the Port of Felixstowe.
Before, I committed my money to that venture, I built a large mathematical model of the proposed business. I found, that there were some unique financial properties to leasing quality trucks, that meant losing large sums of money were difficult.
I wouldn’t be surprised that leasing battery energy storage (BESS) systems have a lot of things going for them, if you have the right contract.
This may explain, why there a large number of companies in the market of providing grid batteries.
- At the top end; Centrica, Rolls-Royce and SSE will supply you with one.
- Funds like Gore Street and Gresham House and others allow you to invest in batteries.
- At the other end of the market are companies like Aura Power.
I suspect, that as with truck-leasing company, the financial flows are very stable and investor-friendly, if you get the model right.
C-Capture Launches Innovative Carbon Capture Trial For Cement Industry
The title of this post, is the same as that of this news item from C-Capture.
This is the sub-heading.
C-Capture, developers of next generation technology for carbon dioxide removal, has launched a new carbon capture trial in the cement manufacturing sector in partnership with Heidelberg Materials.
This is the first paragraph.
The trial, which utilises C-Capture’s innovative solution for industrial decarbonisation, is taking place at Heidelberg Material’s cement manufacturing plant in Ketton. It forms part of C-Capture’s national project, ‘XLR8 CCS – Accelerating the Deployment of a Low-Cost Carbon Capture Solution for Hard-to-Abate Industries’. Working with project partners across the UK, C-Capture’s XLR8 CCS project will demonstrate that a low-cost carbon capture solution is a reality for difficult-to-decarbonise industries in the race to net zero.
I wrote about C-Capture’s technology in Could Drax Power Station Solve The Carbon Dioxide Shortage?
The technology appears to have been spun out of Leeds University.
BP and Drax are investors.
This page on the C-Capture web site is called Technology and has a very neat interactive guide to how the technology works.
Conclusion
I have high hopes for this company and its technology.
NSTA Reveals Winners Of Latest North Sea Licensing Round
The title of this post, is the same as that of this article on Energy Voice.
This is the sub-heading.
The North Sea Transition Authority (NSTA) has issued 31 new exploration licences as part of the third tranche of its latest Licensing Round, with firms including Hartshead Resources, Neptune Energy and Perenco UK among the winners.
These first two paragraphs give more detail.
The NSTA said the licences offered in the latest round are expected to add an estimated 600 million barrels of oil equivalent (mmboe) up to 2060, or 545mmboe by 2050.
The release of the third tranche follows the awarding of 27 licences in the first tranche in October last year, and 24 licences awarded in the second tranche in January.
Surely, with the growth of wind in the next twenty years, this oil and gas will get the UK through to 2050.
Hopefully too, we’ll need to import less oil and gas.
Conclusion
I would rate this as good news.
SSE Renewables Buys 100MW/200MWh Northern Ireland BESS Project
The title of this post, is the same as that of this article on Energy Storage News.
These five paragraphs describe the acquisition and SSE Renewables progress as they build a portfolio of Battery Energy Storage Systems.
A 100MW/200MWh BESS project in Northern Ireland has been acquired by the renewable energy development subsidiary of UK-headquartered power generator and developer SSE.
The 2-hour duration Derrymeen battery in Dungannon, County Tyrone was bought from developer Heron Energy and would be the largest installed BESS facility in Northern Ireland when online.
Subject to a final investment decision by SSE Renewables, the shovel-ready project will be constructed on a greenfield site located outside Coalisland, around five miles from Dungannon.
If approved for final delivery, construction could commence early next year and the BESS would be operational by the end of 2026. It will connect to the grid via an underground cable to the nearby existing Tamnamore substation.
This is SSE Renewables’ first battery storage development in Northern Ireland, having already an established green portfolio in Britain. The firm launched its first operational BESS in the GB market on 15 April in the form of a 50MW/100MWh asset located in Salisbury, Wiltshire.
This battery is a two-hour battery, as are the other two batteries, that are mentioned in the article, that are being developed by SSE Renewables.
Is this a standard for SSE Renewables?
Rolls-Royce Supplies Large-Scale Battery Storage For Grid Stabilization And Electricity Trading To Encavis
The title of this post, is the same as that of this press release from Rolls-Royce.
These two bullet points, act as sub-headings.
- mtu EnergyPack system with 24 megawatt hours to balance out volatile power generation from renewable energies and increase security of supply
- Commissioning of the storage system based on lithium-ion technology in the first quarter of 2025
This paragraph outlines the project.
Rolls-Royce is supplying an mtu battery energy storage system with an output of 12 megawatts and a storage capacity of 24 megawatt hours to Encavis AG. The battery system will support the Hamburg-based electricity producer in trading the electrical energy generated by German wind and solar parks by, among other things, balancing out fluctuations in generation and increasing security of supply. Rolls-Royce will supply and install the energy storage system on a turnkey basis. It is expected to go into operation in the first quarter of 2025.
Note.
- The deal includes construction, installation and ten years of maintenance.
- The battery can supply full power for two hours.
- The battery is supporting renewables.
- In Would You Buy A Battery Energy Storage System From Rolls-Royce?, I looked at a mtuEnergyPack in detail.
- The respective capacity value and efficiency of the plant are guaranteed over the entire term.
This looks to be a very professional deal.
Conclusion
This is the second press release on the corporate web site after Rolls-Royce Supplies mtu Large-Scale Battery Storage To Secure The Latvian National Grid, that was published a month ago, that talks about the mtuEnergyPack.
Could it be that Rolls-Royce are looking for a share of the UK market for grid batteries?
Huge Boost To UK Supply Chain As National Grid Launches The Great Grid Partnership With Seven New Industry Partners, All United In The Drive To Deliver The Great Grid Upgrade
The title of this post, is the same as that of this press release from National Grid.
These five bullet points act as sub-headings.
- National Grid launches pioneering ‘enterprise model’ as response to UK supply chain and skills shortage, announcing the first seven supply chain partners to form the Great Grid Partnership.
- The Partnership, which will initially focus on the network design and construction work required by the end of the decade for nine major infrastructure projects across England and Wales, forms part of a £9bn supply chain framework which will also support infrastructure projects beyond 2030.
- The Partnership will support supply chain capacity and foster collaboration across best practice and skills, delivering benefits for consumers and the wider UK economy.
- This investment further underlines National Grid’s commitment to the people, jobs and skills required to help deliver the energy transition.
- Investment in the UK’s electricity network industry will contribute an average of £18.4bn to GDP and support around 220,000 jobs each year between 2024 and 2035.
These three paragraphs introduce the Great Grid Partnership.
In a major boost to the UK supply chain, National Grid has today launched the Great Grid Partnership. The company, which sits at the heart of the UK energy transition, has named the seven partners who will support the delivery of an initial nine Accelerated Strategic Transmission Investment (ASTI) projects.
The ASTI projects form a key part of The Great Grid Upgrade, which is building the significant new electricity network infrastructure required to reduce the UK’s reliance on fossil fuels by connecting 50GW of offshore wind by 2030.
This new ‘enterprise model’ is a collaborative partnership, bringing together National Grid’s supply chain partners. Two design and consenting service partners [AECOM Arup (JV); WSP], and five construction partners [Laing O’Rourke; Morgan Sindall Infrastructure; Morrison Energy Services; Murphy; Omexom / Taylor Woodrow (OTW)] are joining National Grid in the newly formed Great Grid Partnership.
I very much feel that the Great Grid Upgrade will be on time, but will the Great Grid Partnership, mean that other important projects will be late, as much of the UK’s competent infrastructure companies will be working for National Grid?
The Anonymous Widower
