Green Light For Orkney Transmission Link
The title of this post, is the same as that of this news item from SSE.
These three paragraphs outline the project.
SSE’s Transmission business, SSEN Transmission, has welcomed today’s publication by Ofgem in which the energy regulator has provisionally approved long awaited and much needed plans to provide a subsea electricity transmission link to Orkney.
The Orkney Islands are home to some of the world’s greatest resources of renewable electricity, from established onshore wind, to emerging marine technologies, where Orkney is at the forefront of global developments in marine energy generation.
Following significant growth in small-scale renewable electricity generation in Orkney, the local electricity network has long been at full capacity and no new electricity generation can connect without significant reinforcements.
This paragraph describes the scope of the project.
SSEN Transmission’s proposed solution would enable the connection of up to 220MW of new renewable electricity and consists of a new substation at Finstown in Orkney, and around 57km of subsea cable, connecting to a new substation at Dounreay in Caithness.
200 MW seems a good return for a substation and forty miles of cable.
Germany Pinpoints 36.5 GW Of Offshore Wind Areas, Publishes Development Plan
The title of this post is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Germany’s Federal Maritime and Hydrographic Agency (BSH) has published a new area development plan for the expansion of offshore wind energy. The plan maps out the build-out of offshore wind by 2030, by when the country is to reach 30 GW of capacity connected to its grid, and sets the stage for further deployment of wind turbines at sea, with the 2035 target of 40 GW estimated to be exceeded.
30 GW of offshore wind by 2030 and 40 GW by 2035 are ambitious targets, but how do we compare?
This news story on the UK Government web site is entitled UK Signs Agreement On Offshore Renewable Energy Cooperation, contains this statement.
The initiative is expected to support the UK’s ambitious targets to increase offshore wind fivefold to 50GW, and deliver 18GW of electricity interconnector capacity – up from 8.4 GW today – by 2030.
I don’t think we compare badly.
Giant Solar Farm Project In Doubt After Disagreement Between Mike Cannon-Brookes And Andrew Forrest
The title of this post, is the same as that of this article on the Guardian.
This is the sub-heading.
Australian billionaires had backed $30bn Sun Cable venture designed to help power Darwin, Indonesia and Singapore but the company has gone into voluntary administration.
It does look like the administrators will be able to continue the project and look for more funding.
Qatar must be in the frame, as this link will probably cut some of their gas sales.
I wrote about this monster project in Sun Cable’s Australia-Asia PowerLink.
I wonder if this administration will have any effects on the prospects of the other giant intercontinental interconnectors?
- EuroAfrica Interconnector – See The EuroAfrica Interconnector
- EuroAsia Interconnector – See The EuroAsia Interconnector
- Morroco-UK Power Project – See Moroccan Solar-Plus-Wind To Be Linked To GB In ‘Ground-Breaking’ Xlinks Project
- TransPacific Interconnector – See Chile Wants To Export Solar Energy To Asia Via 15,000km Submarine Cable
The economics will decide. But I do think, the last one could be a bit ambitious.
Ofgem OKs Transmission Investments Needed For UK’s 2030 Offshore Wind Target
The title of this post, is the same as that, of this article on offshoreWIND.biz.
This is the sub-heading.
Ofgem has approved the strategic electricity transmission reinforcements required to deliver the UK Government’s 50 GW offshore wind by 2030 target, set out as part of the regulator’s Accelerated Strategic Transmission Investment (ASTI) framework.
A map then shows the principle new transmission reinforcements.
These include two 2 GW subsea HVDC links from Peterhead to England, both of which will be taken forward as joint ventures with National Grid Electricity Transmission (NGET), a 2 GW subsea HVDC link from Spittal in Caithness, connecting to Peterhead, as well as a 1.8 GW subsea HVDC link from Arnish on the Western Isles to the Beauly area near Inverness.
The approval also implies 400 kV onshore reinforcements, between Beauly, Blackhillock, New Deer and Peterhead; between Beauly, Loch Buidhe and Spittal; and between Kintore, Tealing and Westfield; and uprating the existing Beauly to Denny line to enable 400 kV operation on both circuits.
All cables seem to lead to Peterhead.
UK and NSEC Strengthen Offshore Renewables Ties
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Members of the North Seas Energy Cooperation (NSEC), the UK, and the European Commission have signed a memorandum of understanding (MoU) to strengthen their cooperation for the development of offshore renewable energy.
The article is based on this article on the European Commission web site, which is entitled North Seas Energy Cooperation And UK Establish Cooperation Framework To Facilitate The Development Of Offshore Renewable Energy.
The full signed text is also in this document on the web site, which is entitled Memorandum of Understanding on offshore renewable energy cooperation.
I have read the MoU and it seems a sensible document for one with eleven signatures.
It lists the following areas of cooperation.
- Hybrid and joint projects
- Maritime and spacial planning
- Support framework and finance
- Best practice in respect of onshore and offshore grid practice
- Sharing of information on new technologies
- Exchange of best practices in relation to the relevant rules, regulations and technical standards
The MoU expects any problems to be resolved by consultations in good faith.
EuroLink, Nautilus And Sea Link
EuroLink, Nautilus and Sea Link are three proposed interconnectors being developed by National Grid Ventures.
EuroLink
EuroLink has a web site, where this is said.
To support the UK’s growing energy needs, National Grid Ventures (NGV) is bringing forward proposals for a Multi-Purpose Interconnector (MPI) called EuroLink, which will deliver a new electricity link between Great Britain to the Netherlands.
EuroLink could supply up to 1.8 gigawatts (GW) of electricity, which will be enough to power approximately 1.8 million homes, as well as contribute to our national energy security and support the UK’s climate and energy goals. We’re holding a non-statutory public consultation to inform you about our EuroLink proposals, gather your feedback to help refine our plans and respond to your questions.
Note, that EuroLink is a Multi-Purpose Interconnector (MPI) and they are described on this page of the National Grid website.
In EuroLink’s case, this means it is basically an interconnector between the UK and The Netherlands, that also connects wind farms on the route to the shore.
- Coastal communities get less disruption, as the number of connecting cables coming ashore is reduced.
- Less space is needed onshore for substations.
- Electricity from the wind farms can be directed to where it is needed or can be stored.
As an Electrical and Control Engineer, I like the MPI approach.
The technology to implement the MPI approach is very much tried and tested.
There are many references to EuroLink terminating at Friston.
Nautilus
Nautilus has a web site, where this is said.
Nautilus could connect up to 1.4 gigawatts (GW) of offshore wind to each country through subsea electricity whilst connecting to offshore wind farm/s at sea. By combining offshore wind generation with interconnector capacity between the UK and Belgium, Nautilus would significantly reduce the amount of infrastructure and disruption required both onshore and offshore.
With this new technology, we hope to reduce the impact of infrastructure on local communities and the environment, as well as support the government’s net zero and energy security targets. We are already working closely with other developers in the area to coordinate activities and minimise impact on local communities. We believe that through improved coordination, the UK government can achieve and support the co-existence of renewable energy with coastal communities.
Nautilus is another MPI.
This is said on the web site.
Last year, National Grid Ventures ran a non-statutory consultation for Nautilus, which proposed a connection at Friston.
NGV holds a connection agreement on the Isle of Grain in Kent as part of its development portfolio and we are currently investigating if this could be a potential location for Nautilus. Until this is confirmed to be technically feasible, Nautilus will be included as part of our coordination work in East Suffolk.
So it looks like, Nautilus could connect to the UK grid at Friston or the Isle of Grain.
Sea Link
Sea Link has a web site, and is a proposed interconnector across the Thames Estuary between Suffolk and Kent.
This is said on the web site about the need for and design of Sea Link.
The UK electricity industry is evolving at pace to help lead the way in meeting the climate challenge, whilst also creating a secure energy supply based on renewable and low carbon technologies.
The demands on the electricity network are set to grow as other sectors of the economy diversify their energy consumption from using fossil fuels towards cleaner forms, the move towards electric vehicles being just one example.
Where we’re getting our power from is changing and we need to change too. The new sources of renewable and low-carbon energy are located along the coastline. We need to reinforce existing transmission network and build new electricity infrastructure in these areas in order to transport the power to where it’s needed. This is the case along the whole of the East Coast including Suffolk and Kent.
To allow this increase in energy generation, we need to reinforce the electricity transmission system. Sea Link helps to reinforce the electricity network across Suffolk and Kent.
Our proposals include building an offshore high voltage direct current (HVDC) link between Suffolk and Kent with onshore converter stations and connections back to the national electricity transmission system.
On the web site, in answer to a question of What Is Sea Link?, this is said.
Sea Link is an essential upgrade to Britain’s electricity network in East Anglia and Kent using subsea and underground cable. The proposal includes approximately 130km of subsea cables between Sizewell area in East Suffolk and Richborough in Kent. At landfall, the cables would go underground for up to 5 km to a converter station (one at each end). The converter station converts direct current used for the subsea section to alternating current, which our homes and businesses use. A connection is then made to the existing transmission network. In Suffolk, via the proposed Friston substation; in Kent via a direct connection to the overhead line between Richborough and Canterbury.
Note, that from Kent electricity can also be exported to the Continent.
All Cables Lead To Friston In Suffolk
It looks like EuroLink, Nautilus and Sea Link could all be connected to a new substation at Friston.
But these will not be the only cables to pass close to the village.
This Google Map shows the village.
Running South-West to North-East across the map can be seen the dual line of electricity pylons, that connect the nuclear power stations at Sizewell to the UK electricity grid.
Has Friston been chosen for the substation, so that, the various interconnectors can be connected to the power lines, that connect the Sizewell site to the UK electricity grid.
This would enable EuroLink, Nautilus and/or Sea Link to stand in for the Sizewell nuclear stations, if they are shut down for any reason?
It does appear from reports on the Internet that the Friston substation is not welcome.
Exploring Opportunities For Coordination
The title of this section is a heading in the EuroLink web site, where this is said.
In response to stakeholder feedback, NGV’s Eurolink and Nautilus projects and NGET’s Sea Link project are exploring potential opportunities to coordinate. Coordination could range from co-location of infrastructure from different projects on the same site, to coordinating construction activities to reduce potential impacts on local communities and the environment.
That sounds very sensible.
How Is The XLinks Project Progressing?
The Wikipedia entry for the XLinks project has this introductory paragraph.
The Xlinks Morocco-UK Power Project is a proposal to create 10.5 GW of renewable generation, 20 GWh of battery storage and a 3.6 GW high-voltage direct current interconnector to carry solar and wind-generated electricity from Morocco to the United Kingdom. Morocco has far more consistent weather, and so should provide consistent solar power even in midwinter.
I ask the question in the title of this post, as there are two articles about the XLinks project in The Times today.
This article is optimistic and is entitled Xlinks Morocco Project Could Throw Britain A Renewable Energy Lifeline.
On the other hand this article is more pessimistic and is entitled Britain ‘Risks Losing Out’ On Green Energy From The Sahara.
This is the first paragraph of the second article.
Sir Dave Lewis has complained of “frustratingly slow” talks with the government over an £18 billion plan to generate power in the Sahara and cable it to Britain. The former Tesco chief executive has warned that the energy could be routed elsewhere unless ministers commit to the scheme.
It appears there have been little agreement on the price.
I have some thoughts.
Will XLinks Get Funding?
Xlinks is going to be privately funded, but I have doubts about whether the funding will be made available.
As an engineer, who was involved in many of the major offshore projects of the last forty years of the last century, I believe that the XLinks project is feasible, but it is only 3.6 GW.
These wind farm projects are also likely to be privately funded.
- SSE’s Berwick Bank project opposite Berwick is 4.1 GW
- Aker’s Northern Horizon off Shetland is 10 GW.
- The Scotwind Leasing Round is 25 GW.
- There is talk of 10 GW being possible off East Anglia.
- 50 GW may be being possible in the Celtic Sea.
- BP is planning 3 GW in Morecambe Bay.
Many of these enormous wind power projects are looking for completion on or before 2030, which is the date given for the Morocco cable.
I do wonder, if those financing these energy projects will find these and other projects better value than a link to Morocco.
Is the Project Bold Enough?
Consider.
- Spain has high levels of solar, wind and hydro power.
- France is developing wind to go with their nuclear.
- Both countries and Portugal, also have mountains for sensibly-sized pumped-storage hydroelectric power stations.
- France, Spain, Portugal and Ireland also have the Atlantic for wind, tidal and wave power.
Perhaps, the solution, is an Atlantic interconnector linking the UK, Ireland, France, Spain, Portugal and Gibraltar to West Africa.
Any excess power would be stored in the pumped-storage hydroelectric power stations and withdrawn as required.
In the UK, the National Grid are already using the huge 7800 GWh Ulla-Førre pumped-storage hydroelectric power station to store excess wind-generated energy using the North Sea Link from Blyth.
To my mind XLinks is just a UK-Morocco project.
BP’s Project In Mauretania
In bp And Mauritania To Explore Green Hydrogen At Scale, I discussed BP’s deal to create green hydrogen in Mauretania.
Is this a better plan, as hydrogen can be taken by tanker to where it is needed And for the best price.
Conclusion
I wouldn’t be surprised to see the XLinks project change direction.
Isle of Man Steam Packet Fears Wind Farm Plans May Disrupt UK Routes
The title of this post, is the same as that of this article on the BBC.
These are the first four paragraphs.
Plans to build two new offshore wind farms in the Irish Sea could disrupt Isle of Man ferry services, a Manx operator has warned.
Energy firms have proposed projects named Morgan and Morecambe in areas between the island and Lancashire.
The Isle of Man Steam Packet Company said the developments could cause navigation issues for its sailings to Liverpool and Heysham in bad weather.
But the project’s backers said it was possible to find “ways to co-exist”.
Given, that the approaches to the Ports of Felixstowe, Immingham, Leith, Liverpool, London Gateway and Tilbury, are littered with hundreds of wind turbines, I would suspect that finding a solution will not be difficult.
Perhaps, The Isle of Man Steam Packet Company is angling for a subsidy.
The Isle of Man Steam Packet Company has a current fleet of three ships.
- The company serves Belfast, Dublin, Heysham and Liverpool.
- All routes will likely be through wind farms in a few years.
- The ships were all built in 1998.
- A new ship is being built in South Korea for delivery in 2023.
- All ships are diesel-powered.
Does The Isle of Man Steam Packet Company have a decarbonisation policy?
With the three wind farms having the following sizes.
- Mona – 1500 MW
- Morgan – 1500 MW
- Morecambe – 480 MW
Perhaps, some of the nearly 3.5 GW could be used to power electric or hydrogen ships to the Isle of Man.
The Isle of Man is also powered currently by the Isle of Man to England interconnector and an 85 MW combined cycle gas turbine power station at Pulrose, in the capital, Douglas.
With all of the wind power surrounding the island, perhaps there is some scope for repurposing the island’s economy.
It’s not the island for steelmaking or heavy industry, but what about a few data centres?
National Grid Invites Local Community To Comment On Proposals For Green Electricity Projects 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 are the four main bullet points.
- New interconnector with Netherlands and subsea cable between Suffolk and Kent will strengthen electricity supplies and transport low carbon power to homes and businesses.
- 8-week public consultations will introduce the plans and ask for views of local communities.
- The proposals include possible co-location of infrastructure (buildings and underground cables.) to reduce the impact on local communities.
- Projects form part of the electricity network upgrades identified across the UK to help deliver the government’s energy security strategy and net zero targets.
Note.
- Eurolink is a subsea electricity cable between Great Britain and the Netherlands.
- Sea Link is a subsea electricity cable between Suffolk and Kent.
- The consultations will start on October the 24th.
This paragraph from the press release describes Eurolink.
Developed by National Grid Ventures, the Eurolink multi-purpose interconnector (MPI) is designed to harness the increasing volumes of offshore wind power in the North Sea and has the potential to power approximately 1.8 million homes. It will enable the connection of offshore wind farms to both the British and Dutch electricity grids via an interconnector, enabling the transport of clean electricity from where it’s produced to where it’s needed most.
And this paragraph describes Sea Link.
Developed by National Grid Electricity Transmission, Sea Link will add additional capacity to the electricity network in Suffolk and Kent, enabling low carbon and green energy to power local homes and businesses and be transported around the country. The proposals outline a preferred route of 10km of onshore and 140km of undersea cables, together with potential landfall and converter station locations at the proposed Friston substation in Suffolk and in Richborough in Kent.
These two new interconnectors would appear to open up the delivery of green electricity to the South-East of England and the Continent.
As I’ve said before, there doesn’t be any shortage of money to build wind farms and interconnectors between Great Britain, Belgium and The Netherlands.
How Much Wind Capacity Is Lined Up Around The South-East Of England?
Wind farms listed in the area include.
- Operation – Dudgeon – 402 MW
- Operation – East Anglia One – 714 MW
- Operation – Greater Gabbard – 504 MW
- Operation – Gunfleet Sands – 184 MW
- Operation -Kentish Flats – 140 MW
- Operation – London Array – 630 MW
- Operation – Rampion – 400 MW
- Operation – Scoby Sands – 60 MW
- Operation – Sheringham Shoal – 317 MW
- Operation – Thanet – 300 MW
- Proposed – East Anglia Three – 1372 MW
- Proposed – Norfolk Boreas – 1386 MW
- Exploratory – East Anglia One North – 800 MW
- Exploratory – East Anglia Two – 900 MW
- Exploratory – Rampion 2 Extension – 1200 MW
- Exploratory – Norfolk Vanguard – 1800 MW
- Exploratory – North Falls – 504 MW
- Exploratory – Sheringham Shoal and Dudgeon Extensions – 719 MW
Note.
- These wind farms total to 12.3 GW.
- As the UK needs about 23 GW, these wind farms can power about half the UK.
- But no matter, as the East Anglian Array is planned to go to 7.2 GW and only 4.7 GW is so far operational or planned.
- So there could be up to another 2.5 GW to come.
This is not bad news for Rishi Sunak’s first days in office.
There’s More To Come
The National Grid press release finishes with these two paragraphs.
Last year, National Grid Ventures also ran a non-statutory consultation on Nautilus, a proposed MPI linking Britain and Belgium, which proposed a connection at Friston. National Grid Ventures is now investigating the potential to move the Nautilus MPI project to the Isle of Grain in Kent.
Much of the UK’s electricity network was built in the 1960s when the country was more reliant on fossil fuels. Today, we need to connect huge volumes of renewable power, such as offshore wind, to the network, to help deliver the government’s energy security strategy and net zero targets and to transition to a cleaner, more affordable, and more independent energy system. New infrastructure, and network upgrades are necessary to get the new clean energy from where it’s generated to where it’s needed.In addition to these proposals in Suffolk and Kent (and the East Anglia GREEN proposals which are currently being consulted on) the need for new network infrastructure has also been identified in North and South Wales, the Scottish Islands and West Coast, the East Coast of Scotland and Aberdeenshire, Lancashire, North-East England, and Yorkshire & Humber.
National Grid have numerous plans to connect up all the renewable energy being developed.
National Grid’s North Sea Link Strengthens Electricity Supply And Repays Its Carbon Cost In Just Six Months
The title of this post, is the same as that of this press release from National Grid.
These are three bullet points from the press release.
- World’s longest subsea electricity cable has been in operation since Oct 2021.
- 5.7 terawatt (TWh) hours of clean power have been shared between GB and Norway, strengthening security of supply for consumers in both countries.
- It has saved 800,000 tonnes of carbon in the first year, paying off its carbon cost after only six months of operation.
This must surely be considered a good start.
These two paragraphs describe the operation in the first year.
During its first year of operation, the link has imported 4.6 TWh of clean electricity – enough to power 1.5 million British homes for a year.
North Sea Link has also exported 1.1 TWh to Norway, demonstrating the vital role that interconnectors play in strengthening energy security and maximising the benefits of clean energy sources for consumers across the UK and Europe.
In The Monster In The Mountains That Could Save Europe’s Winter, I describe what makes the North Sea Link so important.
It gives the UK access to the Norwegian Bank Of Electricity or Ulla-Førre, which is a complex of five hydroelectric power stations and a massive lake in the Norwegian mountains to the East of Stavanger.
- The power stations have a total generating capacity of 2.1 GW.
- Lake Blåsjø is able to hold enough water to generate 7800 GWh of electricity.
- Ulla-Førre can also supply electricity to Germany, through the 1.4 GW NordLink.
If Ulla-Førre has a problem, it is that if Norwegian weather is dry, the filling of Lake Blåsjø could be difficult, which is where the interconnector comes into its own, as excess UK wind power or the 1,185 MW Hartlepool nuclear power station, can be used to send electricity to Norway for storage.
In An Update To Will We Run Out Of Power This Winter?, I predicted we will add the following capacity to our renewable generation in the next three years.
- 2023 – 2925 MW
- 3024 – 3726 MW
- 2025 – 6476 MW
This is a total of 13,127 MW.
As a Control Engineer, I can see the following happening.
- Several of the UK’s gas-fired power stations will be mothballed.
- Some of the UK’s gas-fired power stations will be fitted with advanced control systems so they can supply more precise amounts of electricity.
- Some UK electricity is stored in Ulla-Førre for onward sale to Germany.
- Some UK electricity is stored in Ulla-Førre for withdrawal back to the UK, when needed.
One of Ulla-Førre’s main tasks could be to ensure that no UK electricity is wasted.
Conclusion
With all these wind generated electricity and electricity transfers, the Crown Estate, National Grid and the Treasury should be coining it.
The Germans are already building the 1.4 GW NeuConnect between the Isle of Grain and Wilhelmshaven to import more electricity.
But I do believe that another interconnector will be needed.
