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.
BW Ideol And Holcim To Explore Use of Low-Carbon Concrete In Floating Offshore Wind
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
BW Ideol and Holcim have signed a Memorandum of Understanding (MoU) for a feasibility study on supplying beneficial low-carbon concrete for the floating offshore wind industry, with particular reference to Scotland.
These are the first three paragraphs.
BW Ideol and Holcim aim to collaborate on optimising the supply of the innovative concrete needed for the intended mass production of BW Ideol’s floaters in the Port of Ardersier.
Low-carbon concrete’s advantages as a building material for offshore wind farms include its durability in marine environments, its local availability and its comparatively lower carbon emissions, the companies said.
The collaboration includes developing specific durable maritime low-carbon concrete mixes with enhanced mechanical performance perfectly suited to slipform application.
This is surely a good development.
Europe’s First Commercial-Scale Floating Offshore Wind Farm Secures All Planning Approvals
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Flotation Energy and Vårgrønn, a joint venture between Plenitude (Eni) and HitecVision, have obtained the offshore planning approval for the Green Volt floating wind farm offshore Scotland.
This is the first paragraph.
With onshore consent announced earlier this month, Green Volt has now received all its planning approvals and remains on track to be the first commercial-scale floating offshore wind farm in Europe.
Note.
- This is the Green Volt web site.
- Capacity will be between 300 and 560 MW.
- It should be fully operational by 2029.
- It is an INTOG wind farm designed to decarbonise offshore oil and gas fields.
It will also have the side effect of bringing more gas ashore in the UK, instead of burning it to power the platforms.
All T-Pylons Fully Wired Up In Major Milestone For Hinkley Connection Project
The title of this post is the same as that of this press release from National Grid.
These three bullet points are sub-headings.
- Hinkley Connection Project’s 116 T-pylons now ‘strung’ with overhead conductors
- Final conductors fixed into place on a row of T-pylons near Yatton, North Somerset
- 460km and 1,288 tonnes of power line have been installed between project’s T-pylons
Seven paragraphs of the press release go into great detail about how the cables were attached.
But I find this image from the press release, is the most interesting part.
Note.
- There are six cables on each diamond earring-shaped insulator.
- There appears to be a second cross-bar between the insulators.
- The pylon has a small footprint on the ground.
- The white dots on the ground look like sheep.
- The base of the pylon, will make a good scratching post for animals, like sheep, cattle and horses.
This second picture is a profile, that I took at Yatton from a passing train.
Note that the second cross-bar is not there. Is it to steady the insulators during the installation of the cables?
This picture shows some of the traditional pylons used to connect the Sizewell site to the National Grid.
I know which ones I prefer.
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.
Hyundai Heavy Sets Sights On Scottish Floating Offshore Wind
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Major South Korean shipbuilder, HD Hyundai Heavy Industries, has signed a Memorandum of Understanding with two Scottish enterprise agencies which is expected to unlock expertise in the design and manufacture of floating offshore wind substructures.
These are the first three paragraphs.
Scottish Enterprise (SE) and Highlands & Islands Enterprise (HIE) signed the MoU with Hyundai Heavy in Edinburgh, described as a “vote of confidence” in Scotland, committing each other to pursue opportunities for floating offshore wind projects in Scotland.
This is the South Korean company’s first agreement in Europe on floating offshore wind manufacturing.
HD Hyundai Heavy Industries is the world’s largest shipbuilding company and a major manufacturer of equipment such as the floating substructures that form a critical part of the multi-billion offshore wind supply chain.
To say this is a big deal, could be a massive understatement, as my history with large Korean companies could say otherwise.
Around 1980, one of the first prestigious overseas projects, that was managed by Artemis was in Saudi Arabia.
- This may have been something like the King Khaled City, but I can’t be sure.
- Most of the hard work on the project was done by labour imported by Hyundai from South Korea.
After a few years, the Korean running Hyundai’s part of the project returned to Korea and he indicated that he would help us break into the Korean market.
Our salesman; Paul, with responsibility for Korea, who sadly passed away last year, told me this tale of doing business in the country.
Our Korean friend had bought a system for Hyundai in Korea and he organised a meeting for important Korean companies, so that Paul could present the system.
Everything went well, with our friend doing the necessary pieces of translation.
When he had finished, Paul asked if there were any questions.
The most common one was “Can we see the contract?”
Contracts were given out and after a cursory read, the leaders of Korean industry, all started signing the contracts.
So Paul asked our Korean friend, what was going on.
After a brief discussion, Paul was told. “If it’s good enough for Hyundai, it’s good enough for my company!”
And that was how we broke the Korean market.
Conclusion
In UK And South Korea Help Secure Millions For World’s Largest Monopile Factory, I talked about Korean company; SeAH Wind’s new monopile factory on Teesside.
In South Korea, UK Strengthen Offshore Wind Ties, I talk about a developing partnership.
In Mersey Tidal Project And Where It Is Up To Now, I talk about Korean involvement in the Mersey Tidal Project.
The Koreans are coming and Hyundai’s endorsement will help.
£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.
More About RICA
This web page is the RICA web site.
This document gives a lot more information.
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.

T-Pylons
There is a chance that this route will not use conventional pylons.
These pictures show the T-pylons, that have been used in Somerset to connect Hinckley Point C power station to the National Grid.
Note.
- They are a Danish design.
- They are shorter than current pylons.
- They have a smaller footprint on the ground.
- The design won a National Grid-RIBA design competition.
- We will probably see them around the country in the next few years.
They are certainly better than the standard ones that connect the Sizewell site to the National Grid, that passed by my first house in Suffolk.
