Is This Better News For Offshore Wind Farm Developers?
Two months ago this article on offshoreWIND.biz was published, which was entitled Offshore Wind Developers Take A Pass On UK’s Fifth CfD Round As Maximum Bid Price Was Too Low.
This was the sub-heading.
The UK government has awarded 3.7 GW of renewable energy projects with Contracts for Difference (CfDs) in its fifth allocation round. Among the 95 new projects that secured CfDs are onshore wind, solar and tidal energy developments – and not a single megawatt of offshore wind.
These are the first three paragraphs of the article.
According to the government, the global rise in inflation and the impact on supply chains presented challenges for projects participating in this round. The government also noted that similar results have been seen in countries such as Germany and Spain.
The industry does not disagree, however, multiple players have voiced their disappointment that the government had not taken these pressures into account for this round and emphasised that the UK’s goal of having 50 GW of offshore wind and 5 GW of floating wind could now be jeopardised.
Last year, the UK awarded CfDs to 7 GW of offshore wind projects alone.
Today, articles with these titles and sub-headings were published on offshoreWIND.biz.
- 50 Developers Express Interest To Build Wind Farms Offshore Portugal
Fifty entities, including individual companies and consortia, from more than ten countries have submitted their expressions of interest to develop offshore wind projects in Portugal as the country prepares for its first auction.
2. Fugro To Survey Site For Lithuania’s First Offshore Wind Farm
Ignitis Renewables has awarded Fugro a contract to conduct a geophysical survey at Lithuania’s first offshore wind farm site.
3. Norway’s Offshore Wind Tender Attracts Seven Applications
Norway’s Ministry of Petroleum and Energy has received seven applications to participate in the tender for the Southern North Sea II offshore wind project area.
4. Project To Retrofit CTV With Hydrogen Fuel Cells Kicks Off
A project to retrofit a crew transfer vessel (CTV) with hydrogen fuel cells, to cut CO2 and NOx emissions while servicing offshore wind farms, has kicked off.
5.Terna Energy Secures Survey Permit for Wind Farm Sites Offshore Greece
Terna Energy has been granted one out of the two first exploration and survey licences issued for pilot offshore wind projects in Greece.
6. UK Increases Offshore Wind Strike Price Ahead Of Next Auction
The government of the United Kingdom has increased the maximum strike price for offshore wind projects in the next Contracts for Difference (CfD) auction by 66 per cent for fixed-bottom and by 52 per cent for floating wind projects.
All would appear to be positive stories.
- Story 1 is about success in Portugal. What are the Portuguese doing right?
- Stories 2 and 5 are about offshore wind development in new countries; Lithuania and Greece.
- Story 3 may not appear significant, but Terje Aasland, who is Norway’s Minister of Petroleum and Energy seemed pleased in the article.
- Story 4 is about development of new technology, which wouldn’t be done if the market was non-existent.
- Story 6 is surely good news for wind farm developers in the UK.
I did leave out three stories, one of which was negative and two were rather boring. But six out of nine isn’t bad.
Is it Getting Better All The Time, as The Beatles once sang?
Octopus Energy Forays Into German Offshore Wind Market With Butendiek Acquisition
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Octopus Energy’s generation arm has made its first offshore wind investment in Germany with the acquisition of a 5 per cent stake in the 288 MW Butendiek offshore wind farm from Ewz, the Zurich Municipal Electric Utility.
This paragraph introduces the wind farm.
Located 32 kilometres west of Sylt Island in the North Sea, the Butendiek offshore wind farm features 80 3.6 MW Siemens Gamesa wind turbines. The project has been operational since 2015, generating enough clean power for 370,000 homes.
It appears to be a mature smaller wind farm. As it has been operating for eight years, the electricity generates and any costs associated with the farm, will be well defined.
If someone made an investment, the return could probably be fairly accurately predicted.
These paragraphs outline Octopus’s strategy for investing in wind farms.
According to Octopus Energy, the deal marks the next step in the company’s global offshore wind strategy and follows its decision to channel more than EUR 1 billion of investment into green energy infrastructure in Germany by 2030.
Since entering the market last year, the company invested in four onshore wind farms with a combined capacity of 100 MW.
Octopus Energy plans to unleash USD 20 billion in offshore wind investment globally.
Besides Germany, the company invested in offshore wind farms in the UK and the Netherlands, as well as in developers of new offshore wind projects including Norway, Sweden, and South Korea.
In World’s Largest Wind Farm Attracts Huge Backing From Insurance Giant, I explain how Aviva invest in wind farms to get a return to back up their pension and insurance businesses.
As Octopus probably understand wind farms as well as, if not better than Aviva, what better place is there for the company to invest their spare cash and customers’ balances?
Octopus and Aviva are almost showing how wind farms can be used as deposit accounts, that generate a predicable return.
I suspect that other assets like energy storage, interconnectors and solar farms, where there is a history of electricity flows and maintenance costs, can also be run as deposit accounts for investors.
I can also see individuals being able to put their money into a bank account backed by renewable assets.
Note.
Crown Estate Mulls Adding 4 GW Of Capacity From Existing Offshore Wind Projects
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Crown Estate has revealed that it is taking steps to enable the generation of up to an additional 4 GW of electricity from several offshore wind projects in development, within the timeframe of the 50 GW 2030 target.
These are the first two paragraphs.
This follows requests from the developers of seven offshore wind farm projects who believe additional capacity can be generated from the areas of the seabed they hold existing rights for.
According to the Crown Estate, the technology has advanced and more capacity could be developed at projects that are already underway.
The seven wind farms are.
- Awel y Môr – Estimates 500 MW – Fixed – RWE
- Dogger Bank D – 1320 MW – Fixed – SSE Renewables, Equinor
- Dudgeon and Sheringham Shoal Extension – 719 MW – Fixed – Equinor
- Five Estuaries – TBD – Fixed – RWE
- North Falls – 504 MW – Fixed – SSE Renewables, RWE
- Rampion 2 – 1200 MW – Fixed – E-ON
Note.
- The Dudgeon and Sheringham Shoal Extensions seem to have been combined.
- One website connected to the wind farm, gives Five Estuaries as 353 MW.
- All are fixed wind farms.
- All are by large, established developers.
The total size is 4596 MW, using 500 MW for Awel y Môr and 353 MW for Five Estuaries.
Uprating by 8596/4596 could give these capacities.
- Awel y Môr – 935 MW
- Dogger Bank D – 2469 MW
- Dudgeon and Sheringham Shoal Extension – 1345 MW
- Five Estuaries – 660 MW
- North Falls – 943 MW
- Rampion 2 – 2244 MW
The total size is 8596 MW
Conclusion
This seems to be a sensible way to increase offshore wind capacity.
Aker Solutions Gets Vattenfall Nod To Start Norfolk Vanguard West Offshore Platform
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Aker Solutions has been awarded a limited notice to proceed contract from Vattenfall for the Norfolk Vanguard West offshore wind farm in the UK. The contract has a balanced risk-reward profile based on principles for long-term collaboration.
Vattenfall seems to be a bit stop and go on their two Norfolk wind farms; Norfolk Vanguard and Norfolk Boreas.
- In Vattenfall Selects Norfolk Offshore Wind Zone O&M Base, I talk about how Yarmouth has been selected as Vattenfall’s O&M Base.
- In Vattenfall Stops Developing Major Wind Farm Offshore UK, Will Review Entire 4.2 GW Zone, I talk about how Vattenfall have put Boreas on hold and they will be reviewing the whole Norfolk Zone.
These four paragraphs outline the work.
The scope of work for Aker Solutions includes the engineering, procurement, construction, and installation (EPCI) of the high voltage direct current (HVDC) offshore substation.
The fabrication of the topside will be executed in a joint venture with Drydocks World Dubai, and the substructure will be fabricated at Aker Solutions’ yard in Verdal, Norway.
Located more than 47 kilometres from the Norfolk coast and with an installed capacity of 1.4 GW, Norfolk Vanguard West will be the first phase of Vattenfall’s Norfolk Offshore Wind Zone, which also includes the Norfolk Vanguard East and Norfolk Boreas developments.
The Norfolk Vanguard West offshore wind farm is subject to regulatory approvals and Vattenfall’s final investment decision.
Note that Vattenfall are now talking about three wind farms; Norfolk Vanguard West, Norfolk Vanguard East and Norfolk Boreas.
These three paragraphs talk about finance and costs from Aker Solutions point-of-view.
According to Aker Solutions, the company will at this stage book a contract value of about NOK 4 billion (about EUR 334 million) in the fourth quarter of 2023 in the Renewables and Field Development segment, reflecting the compensated work that is to be performed until the expected final investment decision.
Following the award, the total contract value for Aker Solutions is estimated to be about NOK 6 billion.
“The development of the entire Norfolk Offshore Wind Zone could ultimately require up to three HVDC platforms in succession, which would improve the long-term predictability and give positive repeat effects and standardization within the supplier industry,” said Sturla Magnus, Executive Vice President of New Build at Aker Solutions.
Could it be that a 3 x NOK 6 billion or £1.3 billion order has convinced Aker Solutions to invest alongside Vattenfall in the three Norfolk wind farms?
This map shows the two farms in relation to the coast.
Note.
- The purple line appears to be the UK’s ten mile limit.
- Norfolk Boreas is outlined in blue.
- Norfolk Vanguard is outlined in orange and has two parts; West and East.
- Cables will be run in the grey areas.
This second map shows the onshore cable.
Note.
- The cables are planned to come ashore between Happisburgh and Eccles-on-Sea.
- Bacton is only a short distance up the coast.
- The onshore cable is planned to go from here across Norfolk to the Necton substation.
This layout would appear to need only one offshore cable for all three wind farms.
Conclusion
Has Aker stepped in to rescue Vattenfall’s 4.2 GW project?
National Grid To Accelerate Up To 20GW Of Grid Connections Across Its Transmission And Distribution Networks
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.
- Connection dates of 10GW of battery projects accelerated at transmission level, and 10GW of capacity unlocked at distribution level, both part of the Electricity System Operator (ESO)’s connections five-point plan.
- Battery energy storage projects connecting to the transmission network to be offered new connection dates averaging four years earlier than their current agreement.
- The accelerated 20GW equates to the capacity of six Hinkley Point C nuclear power stations.
- Work is part of ongoing collaborative industry efforts, together with Ofgem and government, to speed up and reform connections.
This is the opening paragraph.
National Grid is accelerating the connection of up to 20GW of clean energy projects to its electricity transmission and distribution networks in England and Wales as part of ongoing collaborative work across industry.
As I write this, the UK is generating 38.5 GW of electricity, so another 20 GW will be a large increase in capacity.
I shall look at what National Grid are proposing in sections.
10 GW Of Battery Power
These two paragraphs, outline the plan for 10 GW of battery power.
On its transmission network, 19 battery energy storage projects worth around 10GW will be offered dates to plug in averaging four years earlier than their current agreement, based on a new approach which removes the need for non-essential engineering works prior to connecting storage.
The new policy is part of National Grid’s connections reform initiative targeting transmission capacity, spearheaded by the ESO – which owns the contractual relationship with connecting projects – and actioned jointly with National Grid Electricity Transmission (ET), the part of the business which designs and builds the transmission infrastructure needed in England and Wales to plug projects in.
It looks to me that someone has been doing some serious mathematical modelling of the UK’s electricity network.
Fifty years ago, I provided the differential equation solving software, that enabled the Water Resources Board to plan, where reservoirs and pipelines were to be built. I have no idea how successful it was, but we don’t seem to have any serious water supply problems, except when there is equipment failures or serious drought.
But modelling water and electrical networks is mathematically similar, with rainfall, pipelines and reservoirs in the water network and power generation, transmission lines and batteries and pumped storage hydroelectricity in the electricity network.
I’d be interesting to know what software was used to solve the mathematical model.
I certainly agree with the solution.
Two of our modern sources of renewable energy; solar and wind are not very predictable, but cost a lot of capital investment to build.
So it is very wrong not to do something positive with any excess electricity generated. And what better place to put it than in a battery, so it can be retrieved later.
The earlier, the batteries come on stream, the earlier, the batteries can save all the excess electricity.
So moving the plug in dates for battery storage four years earlier is a very positive thing to do.
A simple calculation shows that for 10 GW, we would need nineteen batteries of about 526 MW.
Ideally, like power stations, they would be spread around the country.
Could Pumped-Storage Hydroelectricity Be Used?
The largest battery in the UK is the Dinorwig pumped-storage hydroelectric power station, which is commonly known as Electric Mountain or Mynydd Gwefru if you’re Welsh.
- It opened in 1984, after a ten years of construction.
- It has a power output of 1.8 GW.
- The energy storage capacity of the station is around 9.1 GWh.
Roughly, every gigawatt of output is backed up by 5 GWh of storage.
If the proposed nineteen new batteries have the same power to storage ratio as Electric Mountain, then each battery will have a storage capacity of 2.63 GWh
SSE Renewables are planning two large pumped-storage hydroelectric power stations in Scotland.
- Coire Glas – 1.5 GW/30 GWh – Possible completion in 2031.
- Loch Sloy – 152.5 MW/25 GWh – See SSE Unveils Redevelopment Plans For Sloy Hydro-Electric Power Station.
A quick calculation, says we’d need seven pumped-storage hydroelectric power stations, which need a lot of space and a handy mountain.
I don’t think pumped-storage hydroelectric would be feasible.
Could Lithium-Ion Batteries Be Used?
My mathematical jottings have shown we need nineteen batteries with this specification.
- An output of about 526 MW.
- A storage capacity of around 2.63 GWh
This Wikipedia entry gives a list of the world’s largest battery power stations.
The current largest is Vistra Moss Landing battery in California, which has this specification.
- An output of 750 MW.
- A storage capacity of 3 GWh
Reading the Wikipedia entry for Vistra Moss Landing, it appears to have taken five years to construct.
I believe that nineteen lithium-ion batteries could handle National Grid’s need and they could be built in a reasonable time.
Could Any Other Batteries Be Used?
Rounding the battery size, I feel it would be better have twenty batteries with this specification.
- An output of 500 MW.
- A storage capacity of 2.5 GWh
Are there any companies that could produce a battery of that size?
Form Energy
Form Energy are well-backed with an MIT heritage, but their largest proposed battery is only 10 MW/1 GWh.
They could be a possibility, but I feel it’s only a small chance.
Highview Power
Highview Power say this about their next projects on this page of their web site.
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.
Note.
- This is more like the size.
- Work is now underway at Carrington – a 50MW / 300MWh plant at Trafford Energy Park near Manchester.
- Highview’s technology uses liquid air to store energy and well-proven turbo-machinery.
- Highview have a co-operation agreement with Ørsted
They are a definite possibility.
10 GW Of Extra Unlocked Capacity
These two paragraphs, outline the plan for 10 GW of extra unlocked capacity.
On its distribution network in the Midlands, South West of England and South Wales, the additional 10GW of unlocked capacity announced recently is set to accelerate the connection of scores of low carbon technology projects, bringing forward some ‘shovel ready’ schemes by up to five years.
National Grid has already been in contact with more than 200 projects interested in fast tracking their distribution connection dates in the first wave of the capacity release, with 16 expressing an interest in connecting in the next 12 months and another 180 looking to connect within two to five years.
This page from National Grid ESO, lists the actions that were taken to release the extra grid capacity.
Conclusion
This looks to be a very good plan from National Grid.
UK And Germany Boost Offshore Renewables Ties
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
A new partnership between the UK and German governments has been agreed on 3 November to help secure safe, affordable, and clean energy for consumers in both nations for the long-term and bolster energy security. Both countries commit to strengthening cooperation in renewables, notably offshore wind and electricity interconnection.
These two paragraphs introduce the deal.
Under the new partnership signed in London by Energy Security Secretary Claire Coutinho and Germany’s Vice Chancellor, Robert Habeck, the UK and Germany have reaffirmed their shared ambition and commitment to net zero and progressing the energy transition.
Europe’s two largest economies have also doubled down on commitments made under the Paris Agreement to limit global warming to 1.5 degrees.
i think this could be a worthwhile follow-up to the relationship, that Boris Johnson and Olaf Scholz seemed to encourage after their high profile meeting in April 2022.
This press release from Downing Street is entitled PM meeting with German Chancellor Olaf Scholz: 8 April 2022 and this is the first two paragraphs.
The Prime Minister welcomed German Chancellor Olaf Scholz to Downing Street this afternoon to discuss the West’s response to Putin’s barbaric invasion of Ukraine.
The two leaders shared their disgust at the Russian regime’s onslaught and condemned Putin’s recent attacks.
I wrote Armoured Vehicles For Ukraine based on some of the things said in the press conference after what seemed to be a very wide discussion.
But it was these paragraphs in the press release that caught my eye.
They also agreed on the need to maximise the potential of renewable energy in the North Sea and collaborate on climate ambitions and green energy.
The Prime Minister said he wanted to further deepen the UK’s relationship with Germany, and intensify its cooperation across defence and security, innovation and science.
After Boris and Olaf’s meeting at Downing Street, I have been able to write these posts about the Anglo-German energy relationship and also make some other observations.
- Mona, Morgan And Morven
- UK-German Energy Link Reaches Financial Close
- RWE, Siemens and other German companies seem to be building a strong presence in the UK.
- Rolls-Royce are doing the same in Germany.
Claire Coutinho and Robert Habeck seem to be wanting to continue the co-operation, judging by this paragraph from the article on offshoreWIND,biz.
The energy and climate partnership sees both countries commit to enhancing cooperation in renewables, particularly in offshore wind and electricity interconnection, including offshore hybrid interconnection.
The most significant part of this paragraph is the mention of offshore hybrid interconnection.
If you want more details on their meeting, this document is the official UK Government declaration.
I have my thoughts.
What Is Meant By Offshore Hybrid Interconnection?
Type “Offshore Hybrid Interconnection” into Google and the first page is this page from National Grid, that is entitled Offshore Hybrid Assets, that has this sub-heading.
How the North Sea has the potential to become Europe’s green energy ‘powerhouse’
This is the introductory paragraph.
Now more than ever we need more renewable energy to make energy cleaner, more affordable, and more secure. The North Sea offers an incredible opportunity for the UK and our European neighbours to deliver huge increases in offshore wind. But delivering new offshore wind will require more infrastructure, which will have an impact on communities.
Hybrid is all-purpose comfort word like cashmere, platinum or puppies.
The page on the National Grid web site describes The Next Generation Interconnector with these paragraphs.
Interconnectors already provide a way to share electricity between countries safely and reliably. But what if they could do much more than that? What if interconnectors could become an offshore connection hub for green energy?
Instead of individual wind farms connecting one by one to the shore, offshore hybrid assets (OHAs) will allow clusters of offshore wind farms to connect all in one go, plugging into the energy systems of neighbouring countries.
And then there is this section entitled Tomorrow’s Solution: Offshore Wind And Interconnectors In Harmony, where this is said.
Today, offshore wind and interconnectors operate alongside each other, connecting to the shore individually. In the future, offshore hybrid assets could enable offshore wind and interconnection to work together as a combined asset.
We now call this type of infrastructure an offshore hybrid asset (OHA), but we used to refer to it as a multi-purpose interconnector (MPI). We changed it because we work so closely together with Europe, it made sense to use the same terminology.
The page on the National Grid web site also has an interactive graphic, which shows the benefit of the approach.
LionLink
National Grid are already developing LionLink, with Dutch grid operator; TenneT, which will be a multi-purpose interconnector linking the UK and the Netherlands.
LionLink is described on this page from National Grid, where this is the sub-heading.
We’re developing a first-of-its-kind electricity link to connect offshore wind between the UK and the Netherlands.
This is the introductory paragraph.
Designed together with our Dutch partners TenneT, LionLink (formerly known as EuroLink) is an electricity link that can supply around 1.8 gigawatts of clean electricity, enough to power approximately 1.8 million British homes. By connecting Dutch offshore wind to Dutch and British markets via subsea electricity cables called interconnectors, LionLink will strengthen our national energy security and support the UK’s climate and energy goals.
Will we be planning a similar electric handshake with the Germans?
How Much Offshore Wind Power Are We Talking About?
This is answered by the last two paragraphs of the article on offshoreWIND.biz.
Around 75 per cent of installed offshore wind capacity in the North Sea is in German and British waters. This is helping to drive the UK’s ambition for up to 50 GW of offshore wind, including up to 5 GW of floating wind, by 2030, the governments said.
Germany is aiming at installing 30 GW by 2030.
That is an Anglo-German starter for eighty GW.
Electrolysers In The Middle If The North Sea
Why Not?
This is a clip from National Grid’s graphic on the page that introduces Offshore Hybrid Assets,
It shows an offshore hydrogen electrolyser.
- You could have an offshore hybrid asset that went between say Bacton in Norfolk and Hamburg via these assets.
- One or more wind farms in UK territorial waters.
- A mammoth offshore electrolyser, with hydrogen storage, possibly in a depleted gas field.
- One or more wind farms in German territorial waters.
Electricity will be able to go three ways; to the UK, to Germany or to the electrolyser.
The Involvement Of German Energy Companies In UK Territorial Waters
Wikipedia lists offshore fifteen wind farms, that have German owners in UK territorial waters, that total 12,960 MW.
This compares with.
- Equinor – 6 wind farms totalling 6466 MW.
- Ørsted – 15 wind farms totalling 9683 MW.
- Scottish Power – 2 wind farms totalling 5,000 MW.
- SSE Renewables – 15 wind farms totalling 15,591 MW.
- Vattenfall – 6 wind farms totalling 4384 MW.
As there is a number of partnerships, these figures only show the relative sizes of the investment by individual companies.
But at nearly 13 GW, the amount of total German investment in UK territorial waters is substantial.
Is This Solely An Anglo-German Club Or Can Others Join?
Consider.
- It seems to me, that because of the LionLink, the Dutch are already involved.
- TenneT is also a large electricity distributor in Germany.
- Countries with substantial shares of the water and winds of the North Sea in addition to Germany, the Netherlands and the UK, include Belgium, Denmark and Norway.
- The UK has interconnectors with Belgium, Denmark, France, Germany, Norway and the Netherlands.
It appears that the world’s largest multi-national power generator is evolving by stealth.
North Sea Wind Power Hub
This concept seems to have developed around 2017, by Danish, Dutch and German interests.
The Wikipedia entry introduces it like this.
North Sea Wind Power Hub is a proposed energy island complex to be built in the middle of the North Sea as part of a European system for sustainable electricity. One or more “Power Link” artificial islands will be created at the northeast end of the Dogger Bank, a relatively shallow area in the North Sea, just outside the continental shelf of the United Kingdom and near the point where the borders between the territorial waters of Netherlands, Germany, and Denmark come together. Dutch, German, and Danish electrical grid operators are cooperating in this project to help develop a cluster of offshore wind parks with a capacity of several gigawatts, with interconnections to the North Sea countries. Undersea cables will make international trade in electricity possible.
Currently, the UK is developing these wind farms on their portion of the Dogger Bank.
- Doggerbank A – 1235 MW – Started producing electricity in 2023.
- Doggerbank B – 1235 MW – Planned commissioning in 2024.
- Doggerbank C – 1218 MW – Planned commissioning in 2025.
- Doggerbank D – 1320 MW – Being planned.
- Doggerbank South – 3000 MW – Being planned.
Note.
- That’s a total of 8 GW.
- A, B, C and D are being developed by a consortium of SSE Renewables and Equinor.
- South is being developed by RWE.
- This web site is for Dogger Bank D.
- This web site is for Dogger Bank South.
This map from the European Atlas of the Seas, shows the various exclusive economic zones (EEZ) in the North Sea.
Note.
- The pinkish zone to the East of the UK, is the UK’s EEZ.
- The light blue zone at the top is Norway’s EEZ.
- The greenish zone in the North-East corner of the map is Denmark’s EEZ.
- The light blue zone below Denmark’s EEZ is Germany’s EEZ.
- Then we have the EEZs for The Netherlands, Belgium and France.
The Dogger Bank is situated where the British, Dutch, German and Norwegian EEZs meet.
All five Dogger Bank wind farms are in British waters.
The Wikipedia entry for the Dogger Bank says this about its size.
The bank extends over about 17,600 square kilometres (6,800 sq mi), and is about 260 by 100 kilometres (160 by 60 mi) in extent. The water depth ranges from 15 to 36 metres (50 to 120 ft), about 20 metres (65 ft) shallower than the surrounding sea.
This probably makes it easy to accommodate a large fixed-foundation wind farm.
Overlaying the map in the Wikipedia entry, with the EEZ map, I’m fairly sure that the northeast end of the Dogger Bank is close to where the EEZs meet.
Progress On The North Sea Wind Power Hub
The North Sea Wind Power Hub has a web site, but it seems to be more about thinking than doing.
It seems to have been hijacked by that august body; The Institute of Meetings Engineers.
This page on the web site, which is entitled Explore The Future Energy Highways, has a simple interactive map.
This shows its vision for 2030.
Note.
- Yellow is electricity links to be built before 2030.
- Blue is hydrogen links to be built before 2030.
- Feint lines indicate the EEZ boundaries.
There are two problems with this layout.
- It doesn’t connect to the Dogger Bank area, where the original plan as detailed in Wikipedia talked about “Power Link” artificial islands.
- No hydrogen is delivered direct to Germany.
This shows its vision for 2050.
Note.
- Yellow, blue and feint lines are as before.
- White is electricity links to be built before 2050.
- There appears to be a node on the Dogger Bank in the German EEZ. This node could be connected to the “Power Link” artificial islands.
- The Southernmost connection to East Anglia could be Bacton.
- The other Norfolk connection could be where wind farms are already connected.
- The Northern connection could be Teesside, where some of the Dogger Bank wind farms connect.
- If the Northern connection to England is Teesside, then first node, which is in the British EEZ, could be one of the offshore sub-stations in the Dogger Bank wind farm complex.
This all seems a lot more feasible.
A New Offshore Hybrid Asset Between Teesside And Germany
Consider.
- A new offshore sub-station will be needed in the German EEZ to connect the “Power Link” artificial islands to the power network.
- The new offshore sub-station will eventually have three interconnectors to the German coast.
- Only the 1218 MW Dogger Bank C wind farm will be connected to the Teesside onshore substation.
- Germany has a power supply problem, after shutting down nuclear power stations and building more coal-fired power stations.
A new Offshore Hybrid Asset between Teesside and Germany could be created by building the following.
- A the new offshore sub-station in the German EEZ to connect the “Power Link” artificial islands to the power network.
- An interconnector between a sub-station of the Dogger Bank wind farm complex and the new sub-station
- A second interconnector to connect the new sub-station for the “Power Link” artificial islands to the German electricity grid.
All of the work would be done mainly in the German EEZ, with a small amount in the British EEZ.
Where Does Dogger Bank South Fit In?
Consider.
- Dogger Bank South is planned to be a 3 GW wind farm.
- It will need a 3 GW connection to the onshore electricity grid.
- Creyke Beck substation is the proposed location for the onshore connection.
- It is owned by German electricity company; RWE.
Could it be that some of the electricity produced by Dogger Bank South is going to be sent to Germany or to another node to produce hydrogen?
It certainly illustrates the value of an Offshore Hybrid Asset.
Flotation Energy, Vårgrønn Seal Exclusivity Agreements For 1.9 GW Scottish Floaters
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Vårgrønn, a joint venture between Plenitude (Eni) and HitecVision, and Flotation Energy have signed exclusivity agreements for two floating offshore wind developments under Crown Estate Scotland’s Innovation and Targeted Oil and Gas (INTOG) leasing round.
These two paragraphs give more details.
Once completed, the floating offshore wind farms, with up to a total of 1.9 GW capacity, will provide renewable electricity to oil and gas platforms, aiming to reduce carbon emissions from the assets they supply.
In addition, Green Volt and Cenos projects will also provide electricity to the UK grid.
Note.
I can’t see a loser with these wind farms.
- The wind farms provide zero-carbon electricity to oil and gas platforms.
- These platforms cut their emissions, by not using fossil fuels to generate the electricity they need for their operation.
- Some platforms use gas to generate the electricity, so this gas can be delivered to the shore for the UK gas network.
- Any spare electricity will be available for using in the UK electricity grid.
- Crown Estate Scotland will be paid for the lease for the wind farm.
There will be no carbon emissions from the platforms, but there will be extra onshore emissions from any gas that is currently used to power the platforms, if it is burnt onshore in power stations and industrial processes, or used for heating.
But increasingly gas in the UK will be used in applications, where the carbon emissions can be captured for use or storage.
It will be very interesting to see how as offshore operations are decarbonised our total carbon emissions change.
UK Companies Forge O&M Services Alliance
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
RES, GEV Wind Power, Outreach Offshore, and Rix Renewables have launched the Offshore Wind O&M Partnership (OWOP) to supply a complete package of long-term operations and maintenance (O&M) services to offshore wind asset owners.
These two paragraphs outline the deal.
The Partnership aims to reduce the complexity and resource intensity associated with the traditional way of subcontracting for multiple O&M services, allowing asset owners to benefit from a much more strategic approach while also ensuring execution to the highest safety standards, according to the press release.
Through just one contract, asset owners will have access to all typical turbine, blade, substation, and balance of plant O&M services as well as workboats and advanced digital tools.
It all sounds like a good deal to me.
Ørsted ‘First’ To Use Giant Autonomous Drones to Transport Cargo To Wind Turbines
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Ørsted says it is the first offshore wind company in the world to use giant autonomous drones to transport cargo to wind turbines
These three paragraphs outline the use of drones.
The Danish offshore wind giant is testing the drones to transport cargo from vessels to its 1.2 GW Hornsea One project in the UK.
Building on its previous experience using smaller drones in other countries, the company is now trialling the 58-kilogram drones with a wingspan of 2.6 metres to transport cargo of up to 68 kilograms.
The drones are operated from existing crew transfer vessels (CVTs) and service operating vessels (SOVs) which are already on site, said Ørsted.
Using drones appears to save cost and time, reduce risk and even allows the deliveries with the turbine working.
With a payload of 68 kilograms, someone my size could even take a lift.
TenneT Installs Artificial Reefs At Hollandse Kust West Alpha Offshore Netherlands
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Dutch-German transmission system operator (TSO), TenneT, has placed several artificial reefs at the Hollandse Kust West Alpha offshore transformer platform in the Dutch North Sea.
These three paragraphs explain the project and the purpose of the reefs.
The platform will connect the Ecowende consortium (Shell/Eneco) wind farm to the high-voltage grid.
In collaboration with Equans/Smulders, TenneT placed two types of artificial reefs near the offshore substation jacket to find out which form works best.
The artificial reefs are part of a series of ecological measures by TenneT to monitor and encourage nature around offshore wind farms.
There is also an excellent picture in the article. All it needs now is fishes swimming through the holes.
