UK Infrastructure Bank, Centrica & Partners Invest £300M in Highview Power Clean Energy Storage Programme To Boost UK’s Energy Security
The title of this post, is the same as that of this news item from Highview Power.
This is the sub-heading.
Highview Power kickstarts its multi-billion pound renewable energy programme to accelerate the UK’s transition to net zero in Carrington, Manchester.
These three paragraphs outline the investment.
Highview Power has secured the backing of the UK Infrastructure Bank and the energy industry leader Centrica with a £300 million investment for the first commercial-scale liquid air energy storage (LAES) plant in the UK.
The £300 million funding round was led by the UK Infrastructure Bank (UKIB) and the British multinational energy and services company Centrica, alongside a syndicate of investors including Rio Tinto, Goldman Sachs, KIRKBI and Mosaic Capital.
The investment will enable the construction of one of the world’s largest long duration energy storage (LDES) facilities in Carrington, Manchester, using Highview Power’s proprietary LAES technology. Once complete, it will have a storage capacity of 300 MWh and an output power of 50 MWs per hour for six hours. Construction will begin on the site immediately, with the facility operational in early 2026, supporting over 700 jobs in construction and the supply chain.
Note.
- The backers are of a high quality.
- The Carrington LDES appears to be a 50 MW/300 MWh battery.
It finally looks like Highview Power is on its way.
These are my thoughts on the rest of news item.
Centrica’s Involvement
This paragraph talks about Centrica’s involvement.
Energy leader Centrica comes on board as Highview Power’s strategic partner and a key player in the UK’s energy transition, supporting Carrington and the accelerated roll-out of the technology in the UK through a £70 million investment. The programme will set the bar for storage energy systems around the world, positioning the UK as the global leader in energy storage and flexibility.
I suspect that Centrica have an application in mind.
In Centrica Business Solutions Begins Work On 20MW Hydrogen-Ready Peaker In Redditch, I talk about how Centrica is updating an old peaker plant.
In the related post I refer to this news item from Centrica Business Systems.
This paragraph in the Centrica Business Systems news item, outlines Centrica’s plans.
The Redditch peaking plant is part of Centrica’s plans to deliver around 1GW of flexible energy assets, that includes the redevelopment of several legacy-owned power stations, including the transformation of the former Brigg Power Station in Lincolnshire into a battery storage asset and the first plant in the UK to be part fuelled by hydrogen.
As Redditch power station is only 20 MW, Centrica could be thinking of around fifty assets of a similar size.
It seems to me, that some of these assets could be Highview Power’s LDES batteries of an appropriate size. They may even be paired with a wind or solar farm.
Larger Systems
Highview Power’s news item, also has this paragraph.
Highview Power will now also commence planning on the next four larger scale 2.5 GWh facilities (with a total anticipated investment of £3 billion). Located at strategic sites across the UK, these will ensure a fast roll-out of the technology to align with UK LDES support mechanisms and enable the ESO’s Future Energy Scenario Plans.
Elsewhere on their web site, Highview Power say this about their 2.5 GWh facilities.
Highview Power’s next projects will be located in Scotland and the North East and each will be 200MW/2.5GWh capacity. These will be located on the national transmission network where the wind is being generated and therefore will enable these regions to unleash their untapped renewable energy potential and store excess wind power at scale.
So will the four larger systems have a 200MW/2.5GWh capacity?
They could, but 200 MW may not be an appropriate output for the location. Or a longer duration may be needed.
Highview Power’s design gives the flexibility to design a system, that meets each application.
Working With National Grid
Highview Power’s news item, also has this sentence.
Highview Power’s technology will also provide stability services to the National Grid, which will allow for the long-term replacement of fossil fuel-based power plants for system support.
Highview Power’s technology is also an alternative to Battery Energy Storage Systems (BESS) of a similar capacity.
How does Highview Power’s technology compare with the best lithium-ion systems on price, performance and reliability?
Curtailment Of Wind Farms
Highview Power’s news item, also has these two paragraphs.
This storage will help reduce curtailment costs – which is significant as Britain spent £800m in 2023 to turn off wind farms.
Highview Power aims to accelerate the roll-out of its larger facilities across the UK by 2035 in line with one of National Grid’s target scenario forecasts of a 2 GW requirement from LAES, which would represent nearly 20% of the UK’s long duration energy storage needs. By capturing and storing excess renewable energy, which is now the cheapest form of electricity, storage can help keep energy costs from spiralling, and power Britain’s homes with 24/7 renewable clean energy.
I can see several wind farms, that are regularly curtailed would have a Highview Power battery installed at their onshore substation.
Receently, I wrote Grid Powers Up With One Of Europe’s Biggest Battery Storage Sites, which described how Ørsted are installing a 300 MW/600 MWh Battery Energy Storage Systems (BESS) at Swardeston substation, where Hornsea Three connects to the grid.
I would suspect that the purpose of the battery is to avoid turning off the wind farm.
Would a Highview Power battery be better value?
What’s In It For Rio Tinto?
I can understand, why most companies are investing, but Rio Tinto are a mining company. My only thought is that they have a lot of redundant holes in the ground, that cost them a lot of money and by the use of Highview Power’s technology, they can be turned into productive assets.
Collateral Benefits
Highview Power’s news item, also has this paragraph.
Beyond contributing to the UK’s energy security by reducing the intermittency of renewables, Highview Power’s infrastructure programme will make a major contribution to the UK economy, requiring in excess of £9 billion investment in energy storage infrastructure over the next 10 years – with the potential to support over 6,000 jobs and generate billions of pounds in value add to the economy. It will also contribute materially to increasing utilisation of green energy generation, reducing energy bills for consumers and providing significantly improved energy stability and security.
If Highview Power can do that for the UK, what can it do for other countries?
No wonder companies of the quality of Centrica, Rio Tinto and Goldman Sachs are investing.
Grid Powers Up With One Of Europe’s Biggest Battery Storage Sites
The title of this post, is the same as that of this article in The Times.
This is the sub-heading.
Orsted’s huge facility in Norfolk will store energy generated by its offshore wind farm
These three paragraphs give more details of the project.
The world’s largest developer of offshore wind farms is planning to build a vast battery storage facility near Norwich.
Orsted will install the energy storage system, which will be one of the largest in Europe, on the same site as the onshore converter station for its Hornsea 3 wind farm in Swardeston, Norfolk.
The project will store energy generated by Hornsea 3 when weather conditions are windy and when electricity supply exceeds demand so that it can be discharged later to help to balance the nation’s electricity grid.
Note.
- There is also a visualisation and a map.
- Tesla batteries will be used.
- The The battery will have an output of 300 MW, with a capacity of 600 MWh. So it is another two-hour BESS.
- It should be operational in 2026.
- The battery is on a 35-acre site.
- Cost is given as £8.5 billion, but that would appear to include the 2852 MW Hornsea 3 wind farm.
The BBC is reporting that local residents are worried about fire safety.
I have some thoughts of my own.
The Location Of The Swardeston Substation
This Google Map shows the location of the Swardeston substation, which will also host the Swardeston BESS.
Note.
- The East-West road is the A 47 Norwich by-pass.
- Norwich is to the North of the by-pass.
- Just to the left-centre of the map, the main A 140 road runs between Norwich and Ipswich, which has a junction with the A 47.
- The A 140 passes through the village of Dunston, which is to the East of the National Grid sibstation, which will host the connection to the Hornsea Three wind farm.
This second Google Map shows the A 140 in detail from the junction to the A 47 to the Swardeston substation.
Note.
- The Swardeston substation is on a substantial site.
- The Norwich to Tilbury transmission line will have its Northern end at Swardeston substation.
- Once the infrastructure is complete at Swardeston substation, Hornsea Three wind farm will be connected to the electricity infrastructure around London.
There would appear to be plenty of space at the site for all National Grid’s plans.
Capital Cost Compared To Big Nuclear
Hornsea Three is a 2852 MW wind farm, that will cost with the battery and a few extras £8.5 billion or around around £ 3 billion per gigawatt.
Hinckley Point C on the other hand will cost between £ 31-35 billion or £ 9.5-10.7 billion per gigawatt.
Conclusion
National Grid would appear to be using a BESS at Swardeston substation to improve the reliability and integrity of the Hornsea Three wind farm.
How many other big batteries will be placed, where large wind farms connect to the National Grid?
As an Electrical and Control Engineer, I certainly, believe that energy storage at major substations, is a proven way to improve the grid.
Do RWE Have A Comprehensive Hydrogen Plan For Germany?
What is interesting me, is what Germany company; RWE is up to. They are one of the largest UK electricity producers.
In December 2023, they probably paid a low price, for the rights for 3 x 1.4 GW wind farms about 50 km off North-East Norfolk from in-trouble Swedish company; Vattenfall and have signed contracts to build them fairly fast.
In March 2024, wrote about the purchase in RWE And Vattenfall Complete Multi-Gigawatt Offshore Wind Transaction In UK.
Over the last couple of years, I have written several posts about these three wind farms.
March 2023 – Vattenfall Selects Norfolk Offshore Wind Zone O&M Base
November 2023 – Aker Solutions Gets Vattenfall Nod To Start Norfolk Vanguard West Offshore Platform
December 2023 – SeAH To Deliver Monopiles For Vattenfall’s 2.8 GW Norfolk Vanguard Offshore Wind Project
Then in July 2023, I wrote Vattenfall Stops Developing Major Wind Farm Offshore UK, Will Review Entire 4.2 GW Zone
Note.
- There does appear to be a bit of a mix-up at Vattenfall, judging by the dates of the reports.Only, one wind farm has a Contract for Difference.
- It is expected that the other two will be awarded contracts in Round 6, which should be by Summer 2024.
In December 2023, I then wrote RWE Acquires 4.2-Gigawatt UK Offshore Wind Development Portfolio From Vattenfall.
It appears that RWE paid £963 million for the three wind farms.
I suspect too, they paid for all the work Vattenfall had done.
This transaction will give RWE 4.2 GW of electricity in an area with very bad connections to the National Grid and the Norfolk Nimbies will fight the building of more pylons.
So have the Germans bought a pup?
I don’t think so!
Where Is Wilhemshaven?
This Google Map shows the location of Wilhemshaven.
Note.
- Heligoland is the island at the top of the map.
- The Germans call this area the Wdden Sea.
- The estuaries lead to Wilhelmshaven and Bremerhaven.
- Cuxhaven is the port for Heligoland, which is connected to Hamburg by hydrogen trains.
This second map shows between Bremerhaven and Wilhelmshaven.
Note.
- Wilhelmshaven is to the West.
- Bremerhaven is in the East.
- The River Weser runs North-South past Bremerhaven.
I’ve explored the area by both car and train and it is certainly worth a visit.
The Wilhemshaven Hydrogen Import Terminal
German energy company; Uniper is building a hydrogen import terminal at Wilhemshaven to feed German industry with hydrogen from places like Australia, Namibia and the Middle East. I wrote about this hydrogen import terminal in Uniper To Make Wilhelmshaven German Hub For Green Hydrogen; Green Ammonia Import Terminal.
I suspect RWE could build a giant offshore electrolyser close to the Norfolk wind farms and the hydrogen will be exported by tanker or pipeline to Germany or to anybody else who pays the right price.
All this infrastructure will be installed and serviced from Great Yarmouth, so we’re not out of the deal.
Dogger Bank South Wind Farm
To make matters better, RWE have also signed to develop the 3 GW Dogger Bank South wind farm.
This could have another giant electrolyser to feed German companies. The wind farm will not need an electricity connection to the shore.
The Germans appear to be taking the hydrogen route to bringing electricity ashore.
Energy Security
Surely, a short trip across the North Sea, rather than a long trip from Australia will be much more secure and on my many trips between the Haven Ports and The Netherlands, I haven’t yet seen any armed Houthi pirates.
RWE And Hydrogen
On this page on their web site, RWE has a lot on hydrogen.
Very Interesting!
H2ercules
This web site describes H2ercules.
The goal of the H2ercules initiative is to create the heart of a super-sized hydrogen infrastructure for Germany by 2030. To make this happen, RWE, OGE and, prospectively, other partners are working across various steps of the value chain to enable a swift supply of hydrogen from the north of Germany to consumers in the southern and western areas of the country. In addition to producing hydrogen at a gigawatt scale, the plan is also to open up import routes for green hydrogen. The transport process will involve a pipeline network of about 1,500 km, most of which will consist of converted gas pipelines.
Where’s the UK’s H2ercules?
Conclusion
The Germans have got there first and will be buying up all of our hydrogen to feed H2ercules.
Ameresco And Envision Energy To Deploy 624MWh UK BESS For Atlantic Green
The title of this post, is the same as that of this article on Energy Storage News.
These three paragraphs describe the project.
Developer-operator Atlantic Green has enlisted system integrator Ameresco and clean energy manufacturer Envision Energy for a 300MW/624MWh BESS project in the UK.
The Cellarhead battery energy storage system (BESS) project will be connected to National Grid’s Cellarhead substation in the West Midlands and have a maximum energy capacity of 624MWh. Construction is expected to begin this year, with final connection to the grid slated for the end of 2026.
The deal between the parties is worth £196.5 million (US$250 million). Ameresco will build the project via an engineering, procurement and construction (EPC) and operation & maintenance (O&M) agreement while Envision Energy will supply the BESS units.
Note.
- It is another battery, that can provide full power for two hours.
- It is another battery, that is located near to one of National Grid’s substations.
As batteries seem to be made by different companies, it looks to me, that National Grid are possibly checking out, which batteries are best.
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.
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?
Electricity Networks Accelerate Potential Connection Dates Of Over 200 Clean Energy Projects
The title of this post, is the same as that of this press release from National Grid.
This is the sub-heading.
7.8GW of clean energy projects, more than double the output of Hinkley Point C nuclear power station, have had their connection offer dates brought forward by up to 10 years through the Technical Limits programme, which is allowing projects to connect to lower voltage distribution networks prior to reinforcement of the high voltage transmission network.
These are the first two paragraphs.
Networks have so far sent offers to 203 projects totalling 7.8GW with an average connection acceleration of 6.5 years. In total 393 projects are eligible for the programme with the further 190 projects able to receive accelerated offers once they have progressed through the connection offer process. Last month a solar farm near Bridgwater in Somerset became the first project to be energised under this scheme. Horsey Levels solar farm, which will provide clean energy for 10,000 homes annually, connected to National Grid’s electricity distribution network significantly ahead of its original planned connection date. This initial acceleration has been delivered in the first phase of the Technical Limits programme, with further phases and analysis planned.
Technical Limits, a collaborative project from National Grid Electricity Transmission, Energy Networks Association, the Electricity System Operator and the Distribution Network Operators (DNOs) forms part of the ongoing collaborative industry efforts, together with Ofgem and government, to speed up and reform connections to the grid. Scottish Transmission and Distribution network owners have been involved in developing the Technical Limits programme and are in the process of rolling out the programme in their license areas also.
Note.
- National Grid seem to measure large amounts of power, with respect to Hinkley Point C nuclear power station, which will have an output of 3.26 GW.
- The Technical Limits programme seems to be a sensible idea.
- Was the idea thought up by National Grid or is it an idea borrowed from another country?
- If it allows another 7.8 GW of clean electricity projects to be connected an average of 6.5 years earlier, then there can’t be much wrong with the idea.
- Horsey Levels solar farm is to the East of the M5, just to the North of Bridgwater.
I shall be following the roll-out of National Grid’s Technical Limits programme, as more clean power projects are connected to the grid.
National Grid And Innovation
This is another post about innovation at National Grid.
Others include.
- £9.2m Electricity Research Project To Save 39,000 Tonnes Of C02 Gets Go-Ahead, which talks about modifying transmission lines to carry more electricity. This means, that theoretically, we’ll need less and smaller transmission lines.
- £400k For National Grid Innovation Projects As Part Of Ofgem Fund To Help Shape Britain’s Net Zero Transition, which talks about Ofgem grants to fund innovation.
- National Grid Fast-Tracks Overhead Line Upgrade Project To Help Accelerate Connection Dates Of 175 Clean Energy Projects, which describes acceleration of projects.
- National Grid To Accelerate Up To 20GW Of Grid Connections Across Its Transmission And Distribution Networks, which also describes acceleration of projects.
- National Grid Goes Carbon-Free With Hydrogen-Powered Substation Trial, which describes work to use hydrogen as back-up power for substations.
- University Of Manchester And National Grid Team Up To Develop SF6-Free Retrofill Solution For Electricity Network, which describes a project to remove SF6 from the grid. SF6 is a greenhouse gas.
- National Grid Installs LineVision Sensors To Expand The Capacity Of Existing Power Lines, which describes an interesting idea from the United States.
- National Grid ESO And Reactive Technologies Launch Flagship Inertia System To Measure Grid Stability, which describes an innovative Spanish way to measure grid stability.
Note.
- I have included projects, that accelerate connection of new projects to the grid.
- Does National Grid benefit from operating grids in the UK and US, as it gets offered the best technology from both sides of the Pond?
National Grid seem to be big innovators.
Mercia Power Response & RheEnergise Working Together To Build Long Duration Energy Storage Projects In The UK
The title of this post, is the same as that as this news item from Mercia PR.
As it is from the 16th of August last year, I wonder why my Google Alert didn’t pick it up.
This is the sub-heading.
Mercia Power Response, a key provider of flexible power response services to the UK grid, has signed an agreement with RheEnergise to explore the potential deployment of RheEnergise’s new and innovative form of long-duration hydro-energy storage, known as High-Density Hydro® (HD Hydro).
These are the first three paragraphs.
Mercia Power Response, a key provider of flexible power response services to the UK grid, has signed an agreement with RheEnergise to explore the potential deployment of RheEnergise’s new and innovative form of long-duration hydro-energy storage, known as High-Density Hydro® (HD Hydro). Mercia Power Response (“Mercia PR”) and RheEnergise will work together to identify suitable sites for additional HD Hydro storage projects. The two companies’ initial focus will be the feasibility of getting 100MW of HD Hydro in commercial operation by 2030 by utilising Mercia PR’s existing grid connections.
With 40 sites having a combined capacity of 263MW and a number of sites under development and construction over the next 5-10 years, Mercia PR believes that RheEnergise’s HD Hydro storage technology would be a complementary, low carbon solution to its operating portfolio.
Additionally, Mercia PR’s industry partners bring market expertise in energy trading and forecasting, helping RheEnergise to optimise grid-connected energy storage projects.
Note.
- The average size of Mercia PR’s batteries would appear to be 6.5 MW.
- Working on the often-used two-hour duration, that would be a storage capacity of 13 MWh.
- I suspect some of Mercia PR’s sites will be more suitable for lithium-ion batteries and some will be more suitable for RheEnergise’s HD Hydro systems.
- I have witnessed local Nimbys objecting to lithium-ion systems on grounds of the fire risk.
- I am fairly sure, that the National Grid will be able to cope with both lithium-ion batteries and RheEnergise’s HD Hydro systems.
- I suspect Mercia PR’s industry partners, with their market expertise in energy trading and forecasting, could turn a small wind or solar farm into a nice little earner.
This looks to be a good fit between two innovative companies.
