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.
National Grid Shares Proposals For Green Electricity Projects In Lincolnshire And West Norfolk, Needed To Boost Home-Grown Energy Supplies And Progress Towards Net Zero
The title of this post, is the same as that of this press release from National Grid.
These four bullet points, act as sub-headings.
- National Grid is inviting communities in East Lindsey, Boston and South Holland in Lincolnshire, and King’s Lynn and West Norfolk, to view proposals for two new primarily offshore electricity infrastructure projects.
- National Grid will consult communities from 23 April – 17 June to introduce the proposed project and ask for local peoples’ opinions.
- Eastern Green Link 3 (EGL 3) and Eastern Green Link 4 (EGL 4) will be able to transport enough clean energy generated in Scotland to power up to four million homes in the Midlands and South of England.
- The projects form part of The Great Grid Upgrade, the largest overhaul of the grid in generations, with new infrastructure across England and Wales helping the UK to meet its net zero ambitions, reduce its reliance on fossil fuels and contribute to lower energy bills over the long-term.
These five paragraphs outline the two projects.
National Grid is inviting communities to comment on early proposals for two green electricity infrastructure projects which will help deliver the UK’s energy security strategy and net zero targets.
The eight-week initial consultation, which begins on 23 April, shares proposals for Eastern Green Link 3 (EGL 3) and Eastern Green Link 4 (EGL 4) projects – two new, primarily subsea high voltage direct current (HVDC) electricity links, with associated infrastructure, between Scotland and England.
National Grid Electricity Transmission (NGET) is jointly developing EGL 3 with SSEN Transmission (SSEN) and EGL 4 with SP Energy Networks (SPEN).
EGL 3 would run from Peterhead, Aberdeenshire, under the North Sea via marine cables to a potential landfall location on the Lincolnshire coastline, either at Theddlethorpe or Anderby Creek. EGL 4 would run from Westfield, Fife, also via marine cables under the North Sea to the same landfall location as EGL 3.
After making landfall, both projects’ cables will run underground for approximately 100km to two proposed converter stations in the Walpole, King’s Lynn and West Norfolk, area. Underground cables would then connect the converter stations to the transmission network via a new proposed substation, also within the Walpole area.
Note.
- These would appear to be early proposals.
- National Grid appear to be planning and consulting on two interconnectors at once.
- There would appear to be a lot of underground cable on land. But then the cables will be dug into good Fenland soil.
- All the electrical gubbins seem to be in the Walpole area.
These paragraphs invite people to comment.
Throughout our initial consultation, we are holding a series of face-to-face events to consult on the electrical infrastructure required in England.
Our consultation events are being held across the project area. Information about our proposals will be on display and copies of maps and technical documents will be available to view. Members of the project team will be available to talk through our proposals and answer any questions.
National Grid have also announced dates of when public information events are being held.
- Tuesday 30 April 2024 – 2pm-7pm – Dunes Complex, Central Promenade, Mablethorpe, LN12 1RG
- Wednesday 1 May 2024 – 2pm-7pm – Anderby Village Hall, Sea Road, Anderby, Skegness, PE24 5YD
- Thursday 9 May 2024 – 12:30pm – 6pm – Alford Corn Exchange, 9 Market Place, Alford, LN13 9EB
- Monday 13 May 2024 – 2pm-7pm – Leverington Village Hall, Gorefield Rd, Leverington, Wisbech, PE13 5AT
- Wednesday 15 May 2024 – 2pm-7pm – Eastville, Midville and New Leake Village Hall, Station Rd, Eastville, PE22 8LS
- Thursday 16 May 2024 – 2pm-7pm – Poachers Country Hotel, Swineshead Road, Kirton Holme, PE20 1SQ
- Monday 20 May 2024 – 2pm-7pm – Walpole Community Centre, Summer Close, Walpole St Andrew, PE14 7JW
- Wednesday 29 May 2024 – 2pm-7pm – The Holbeach Hub, Boston Rd South, Holbeach, PE12 7LR
- Wednesday 5 June 2024 – 2pm-7pm – Burgh le Marsh Village Hall, Jacksons Lane, Burgh le Marsh, Skegness, PE24 5LA
I would have hoped, that some of the venues would have been easier to get to by public transport.
I have some thoughts and observations.
What Will Be The Capacity Of Green Link 3 And Green Link 4?
I can find references to the capacity of Eastern Green Links 1-4 and it appears that all four have a capacity of 2 GW.
A Map Of Green Link 3 And Green Link 4
I have found this map of Green Link 3 and Green Link 4.
National Grid are going to be busy, as they’re also building Green Link 1 and Green Link 2.
Will Green Link 3 And Green Link 4 Share A Route Between The Coast And Walpole?
There is only one green HVDC onshore cable on the map. But surely laying two 2 GW cables in the same trench will cost less, than digging two cable routes.
Looking at the three converter stations would appear to confirm that Green Link 3 and Green Link 4 share a route.
Will Landfall Be At Theddlethorpe Or Anderby Creek?
This Google Map shows the coast between Theddlethorpe and Anderby Creek.
Note.
- The decommissioned Theddlethorpe gas terminal is indicated by the red arrow.
- The seaside resort of Mablethorpe lies between the two possible landing sites.
- Anderby Creek is in the South-East corner of the map.
This second Google Map shows the Theddlethorpe Gas Terminal and the North of Mablethorpe.
Note.
- The decommissioned Theddlethorpe gas terminal is indicated by the red arrow.
- Mablethorpe beach appears to be on a high quality.
Both sites would appear to be strong possibilities.
Both sites have plenty of space, but the Theddlethorpe gas terminal is a large brownfield site.
The Anderby Creek site would probably be a shorter underground cable across Lincolnshire.
The Triton Knoll Wind Farm
The Wikipedia entry for the Triton Knoll wind farm starts with these two paragraphs.
Triton Knoll Wind Farm is an 857 MW round 2 offshore wind farm 33 kilometres (21 mi) off the coast of Lincolnshire, in the North Sea, England.
RWE Npower Renewables were awarded the lease to the development area in 2003. The offshore elements of the wind farm of up to 1200MW power gained planning consent in 2013; RWE reduced the scope of the wind farm to 900MW or under in 2014, to reduce cost per MW.
Note.
- The wind farm was commissioned in January 2022.
- The wind farm cables make landfall at Anderby Creek.
- They then travel underground to Bicker Fen substation.
This Google Map shows Bicker Fen and Anderby Creek.
Note.
- Bicker Fen substation is in the South-West corner of the map and is indicated by a red arrow.
- Anderby Creek is in the North-East corner of the map.
- The cable is underground.
- This page on the Murphy Group website, describes the work the company did to install the cables.
- It appears from the Murphy document, that there are six cables between Anderby Creek and Bicker Fen.
This Google Map shows Anderby Creek.
Could the scar across the land to the West of Anderby Creek, be the connection to the offshore Triton Knoll wind farm?
I think it is! And I also think that it can carry more than just the 857 MW Triton Knoll wind farm!
I am suspicious, that one of Baldrick’s ancestors has been at work and the Triton Knoll export cable system could be used to connect Green Link 3 and Green Link 4 to Bicker Fen and Walpole substations.
This would surely allow Scottish wind power to be sold to Denmark and then sold onward to Germany.
The VikingCCS Project
The VikingCCS project is a carbon capture and storage project, that is proposed to be based at the decommissioned Theddlethorpe gas terminal.
The VikingCCS project has a web site.
Would the use of the Theddlethorpe gas terminal mean that it is more likely that Green Link 3 and Green Link 4 will make a Southern landfall at Anderby Creek?
Will There Be A Connection To Viking Link?
The Viking Link is a 1400 MW at 525 KV electricity interconnector between Bicker Fen in Lincolnshire and Revsing in Jutland, Denmark.
This Google Map, shows the location of Bicker Fen, about halfway between Boston and Sleaford.
This second map shows the position of the current Walpole substation with respect to the Wash.
Note.
- Bicker Fen is in the North-West corner of the map.
- The current Walpole substation is marked by the red arrow.
- King’s Lynn is in the South-East corner of the map.
I suspect, if National Grid wanted to connect Green Link 3 and Green Link 4 to the Viking Link, then this would be possible.
If the Viking Link were to be connected to Green Link 3 and Green Link 4, this would allow surplus Scottish renewable energy to be sent to Denmark and on to Germany.
Green Link 3, Green Link 4 And Viking Link Appear To Be Underground In Lincolnshire
I can’t find any trace of overhead cables for the Viking Line in Lincolnshire and the press release says this about Green Link 3 and Green Link 4.
After making landfall, both projects’ cables will run underground for approximately 100km to two proposed converter stations in the Walpole, King’s Lynn and West Norfolk, area.
The connection to the Triton Knoll wuind farm is also underground.
It does appear that National Grid, are going for a Nimby-friendly approach for cables between Walpole and the coast.
Hopefully putting the cables underground will save money in legal arguments and fees.
New National Grid Substation Fully Operational, Transmitting Clean Power To 1.5 Million Homes
he title of this post, is the same as that of this press release from National Grid.
These three bullet points act as sub-headings.
- National Grid’s new Littlebrook 400kV substation in Dartford, Kent is now fully energised.
- The facility enables the transmission of 2GW of low carbon and renewable energy from interconnectors and offshore wind farms off the coast of Kent to power around 1.5 million homes.
- New technology deployed to reduce emissions at the site.
This is the first three paragraphs, which outline the project.
National Grid has successfully commissioned a new, state-of-the-art substation, in Dartford, Kent, enabling 2 gigawatts (GW) of low carbon and renewable energy to power around 1.5 million homes.
National Grid and its contractors Balfour Beatty and GE Vernova’s Grid Solutions have been working since June 2019 to build a replacement for Littlebrook 400kV substation.
The new facility will help to reduce the use of sulphur hexafluoride (SF₆), a gas commonly used in the electrical industry to prevent short circuits and to keep the network safe and reliable.
These two paragraphs explain how the new substation fits in with National Grid’s SF₆ policy.
Engineers are using GE Vernova Grid Solutions’ innovative g3 gas-insulated busbar equipment which is SF6- free. A total of 5.6 tonnes of SF₆ gas has been saved, forming part of National Grid’s ambition to reduce its SF₆ emissions by 50% by 2030 and removing all SF₆ gas from electrical assets by 2050.
Teams have also deployed net zero construction methods throughout the project to reduce the environmental impact of the works, including steel manufactured in Britain, solar powered electrics, electric vehicle charging points, biodiversity net gain plan for the local area and an onsite biodigester to manage wastewater, all saving 5229 tonnes of CO₂ emissions during construction.
National Grid have this page on their web site, which is entitled What Is SF6? Sulphur Hexafluoride Explained, where this is the first paragraph.
Sulphur hexafluoride – also known as SF6 – is a ‘greenhouse gas’ that has long played a part in global warming, similar to that of carbon dioxide (CO2).
Hence the need for its removal.
Conclusion
Removal of sulphur hexafluoride from the world’s electricity substations and switchgear will be a very large task.
National Grid Launches Viking Link, The Next Step Towards A North Sea Super-Grid
The title of this post, is the same as that of this press release from National Grid.
These four bullet points act as sub-headings.
- The £1.8bn project connecting the UK with Denmark was launched today.
- With a capacity of 1.4GW, Viking Link will be able to power up to 2.5 million UK homes and is the longest land and subsea cable in the world.
- Viking Link will deliver £5.2bn in benefits to UK consumers.
- As the UK’s first connection with renewable energy-rich Denmark, Viking Link will be instrumental in both countries achieving net zero carbon emissions.
The press release then gives all the details of the latest of National Grid’s sixth interconnector.
As a Control Engineer, I like this interconnector.
- Denmark and the UK are both importers of electricity.
- The UK has 30 GW of wind power and Denmark has 7 GW.
- The UK has almost 15 GW of solar power and Denmark has 3.5 GW.
- The UK has 6 GW of nuclear and Denmark banned nuclear in 1985.
- Both the UK and Denmark use large amounts of biomass to generate electricity.
- As the sun goes East to West, Denmark will produce its daily peak solar before the UK.
- If the prevailing winds go West to East, the UK will produce its daily peak wind before Denmark.
It looks to me that a UK-Denmark interconnector could perform a valuable job, by balancing the UK’s electricity peaks and troughs with those of Denmark.
The system could be improved in two ways.
- If Southern England has a sunny, windy day, there may be need for substantial energy storage.
- The route between the UK and Denmark could be via a large offshore wind farm in the North Sea.
Vind∅ is a proposed Danish energy island in the North Sea.
There’s more about the Viking Link on its web site.
This is the introduction on the home page.
Viking Link is a 1400 MW high voltage direct current (DC) electricity link between the British and Danish transmission systems connecting at Bicker Fen substation in Lincolnshire and Revsing substation in southern Jutland, Denmark.
The project involves the construction of converter sites and installation of onshore and offshore cable in each country. These are then connected to the substations.
Viking Link is approximately 765 km long and allows electricity to be exchanged between Great Britain and Denmark.
The interconnector enables the more effective use of renewable energy, access to sustainable electricity generation and improved security of electricity supplies. It also benefits the socio economy of both countries.
This is going to be a very valuable interconnector for the UK, Denmark and those that own it.
£9.2m Electricity Research Project To Save 39,000 Tonnes Of C02 Gets Go-Ahead
The title of this post, is the same as that of this press release on National Grid.
These four paragraphs detail the project.
National Grid Electricity Transmission (NGET) has been successful in securing £8.12m of funding from Ofgem’s Network Innovation Competition (NIC) to research the uprating of overhead lines, with the remainder being funded by National Grid.
The RICA (Retro-Insulated Cross-Arms) research project will commence in early 2021 and aims to develop an innovative method for uprating overhead lines, allowing the voltage on 275kV overhead lines to be increased to 400kV. This potentially paves the way for uprating 400kV lines to 550kV in the future.
By removing the suspended insulators on these overhead lines and instead insulating the cross arms, the wires will be held higher and further apart, thereby enabling an increased voltage to be carried.
Uprating lines in this way could allow 45% more power to be carried on some existing routes and support significant reductions in UK CO2 emissions – 39,000 tonnes. This could deliver up to £286m of efficiencies to consumers and with future development, it could open the door to ultra-high voltage networks in the UK.
This is a National Grid picture of fitters installing the new system.
Note.
- Surely, if you can increase the capacity of an electricity line by 45 %, by using innovation and just changing the insulators, this would be much cheaper, than adding another high voltage line.
- It would also incur less legal costs and disruption, than a second line.
I like this idea and hopefully it will please the Nimbies.

Conclusion
It appears to be a simple solution to increasing the capacity of the grid.
I’d like to see some recent results.
Opportunity For Communities To Have Their Say On New Clean Energy Substation Proposed In High Marnham
The title of this post, is the same as that of this article on National Grid.
These three bullet points act as sub-headings.
- National Grid is consulting communities from 22 April to 20 May 2024 on its plans for a new electricity substation which will strengthen its network and connect clean energy to the grid – part of The Great Grid Upgrade
- Substation crucial to upgrade critical infrastructure and ensure a secure and reliable supply of clean energy
- Local people invited to attend consultation events to learn more about the proposals
This is the first paragraph.
National Grid is making changes to its network of electricity infrastructure that transports power around the country, in order to connect new sources of power generated from offshore wind and other low carbon sources to the homes and business across Britain.
These two paragraphs detail the work at High Marnham.
The Great Grid Upgrade is the largest overhaul of the grid in generations. It will play a large part in the UK government’s plan to boost homegrown power, helping the UK switch to clean energy and make sure our electricity network is fit for the future; carrying more clean, secure energy from where it’s generated to where it is needed.
As part of the Brinsworth to High Marnham project, National Grid is proposing to build and operate a new 400kV substation immediately west of its existing substation site in High Marnham. The new substation, which forms a key part of The Great Grid Upgrade, will play an important role in building a more secure and resilient future energy system and provide the ability to transport cleaner energy from the North of England to homes and businesses across the Midlands and beyond, helping to reduce our reliance on fossil fuels.
This is a 3D Google Map of the current sub-station.
Note.
- The three large circles are the bases of the cooling towers of the former High Marnham power station.
- The 9.3 MW HyMarnham electrolyser will be built on the site of the demolished coal-fired power station.
- The current sub-station is in the South-West quarter of the power station site.
- The new substation will be on the West side of the current substation.
It is a large site, with space for more electrical gubbings.
The Consultation
There is a web site, a webinar and two local in-person meetings.
- Friday 26 April from 2pm – 7pm at South Clifton Coronation Hall, South Clifton, Newark, Nottinghamshire, NG23 7BG
- Saturday 27 April from 9am – 2pm at Normanton on Trent Village Hall, South Street, Normanton on Trent, NG23 6RQ
This is the third Opportunity For Communities To Have Their Say in a few days.
I can’t fault that!
