Floating Wind Farms At Sea To Create 29,000 Jobs – Crown Estate
The title of this post, is the same as that of this article on the BBC.
These three paragraphs introduce the article.
Plans to generate electricity through floating wind farms off the south Wales coast could create thousands of new jobs, according to the Crown Estate.
The property business owned by the monarch but run independently said the new industry could create about 29,000 jobs, including 10,000 in Wales.
It is leasing the space to generate enough power for four million homes.
Will Wales be the world’s next offshore wind powerhouse?
Wind power experts have said there is a potential for 50 GW of offshore wind power in the Celtic Sea and the BBC article talks of an investment of £43.6 billion by 2050.
The process has started, but will the engineers be able to tame the dragons?
RWE Looking for Innovators To Boost UK’s Offshore Wind Supply Chain
The title of this post, is the same as that of this article on offshoreWIND.biz.
RWE appear to be looking for innovators in three areas.
- Autonomous solutions and the best way to integrate them into wind farm site investigations, construction, and operations and maintenance (O&M) is the first challenge for which RWE is looking for responses.
- The second challenge is about solutions to measure and reduce the environmental impacts of offshore wind farm construction and operations on birds.
- The last challenge focuses on ideas and innovations in cable monitoring and protection, aiming to secure a reduction in offshore wind farm cable failures.
As sums of around £25,000 are talked about in the article, it could be worth applying, if you have a relevant idea.
Is it slightly flattering to the UK’s skills, that a German company is backing British innovation?
But then I was involved in a British invention, which was also backed by the Germans and made me a reasonable amount of money.
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.
National Grid Installs LineVision Sensors To Expand The Capacity Of Existing Power Lines
The title of this post, is the same as that of this press release from National Grid.
These are four bullet points from the press release.
- LineVision’s Dynamic Line Rating (DLR) technology trialled for first time in Great Britain following successful deployment on National Grid’s electricity networks in the US.
- The sensors and data analytics platform will highlight spare capacity on overhead power lines allowing for the integration of more renewable power.
- Technology has the potential to unlock 0.6GW of additional capacity, enough to power more than 500,000 homes and save £1.4 million in network operating costs per year based on the results from the US networks.
- Combined with the construction of new infrastructure, the innovative technology forms part of National Grid’s work to upgrade and adapt the electricity network to meet increased demand and help deliver a net zero grid.
In some ways this seems like the sort of story, that could be filed under Too-Good-To-Be-True.
But as a Graduate Control Engineer, I’m willing to give National Grid and LineVision the benefit of the doubt.
- It appears to be technology proven in the United States.
- That experience should feed over, once the manuals are translated into the dual English-American form of English.
- I suspect that applying this technology to interconnectors could increase their capacity.
- I also think that as we add more storage, power sources or interconnectors to our electricity network, this will open up more savings.
- As the UK power network gets more complicated, the system should come into its own.
This is an excellent decision by National Grid.
French Farmers Are Covering Crops With Solar Panels To Produce Food And Energy At The Same Time
The title of this post is the same as that of this article on euronews.green.
These paragraphs explain the technique.
Agrivoltaics – the practice of using land for both solar energy and agriculture – is on the rise across France.
In the Haute-Saône region, in the northeastern part of the country, an experiment is being conducted by solar-energy company TSE. It is hoping to find out whether solar energy can be generated without hindering large-scale cereal crops.
Previous attempts to experiment with agrivoltaics have been through smaller-scale projects. But, keen to see if it can thrive on an industrial level, 5,500 solar panels are being spread over this farm in the commune town of Amance by TSE.
The article also contains a picture, which shows panels high in the air and a tractor going underneath.
I’m not sure of the idea’s practical application, although, I do know of a farmer, who is experimenting with using solar panels in a field with sheep. He also has found that on another field fully fitted with solar panels, hares were thriving.
In Understanding Floatovoltaics, I talked about another French idea; floating solar panels, where solar panels are floated on calm water like a reservoir.
Talking of reservoirs, I remember seeing a Tomorrow’s World, as a child, where it was proposed that concrete reservoirs, like those under the Heathrow flightpath, be filled with foamed concrete and covered with soil, so they could be used to grow crops.
- The water capacity would be slightly smaller.
- There would be less water losses.
I wonder what happened to that idea.
Groundbreaking Green Energy Hub Planned For Former Thorpe Marsh Power Station Site
The title of this post, is the same as that of this press release from the Banks Group.
This is the introductory paragraph.
Outline plans are set to be revealed for the creation of a groundbreaking green energy hub at the former Thorpe Marsh power station site near Doncaster.
Other details include.
- The 1 GW Thorpe March coal-fired power station closed in 1994 and was demolished in 2012.
- The project would take advantage of the site’s existing 1,450MW connection to the National Grid.
- The storage capacity will be 2.8 GWh.
- The site is a a 65-hectare area of land to the west of the village of Barnby Dun.
It is thought to be the largest battery energy storage system currently being planned in the UK, and one of the largest anywhere in the world.
T have a few thoughts.
The Site At Barnby Dun
This Google Map shows the site to the West of Barnby Dun.
Note.
- The power station site is indicated by the six cooling towers.
- The Doncaster and Hull railway line runs across the map to the North of the cooling towers.
- The cooling towers were demolished in 2012, according to Wikipedia.
- More recent images on the web show a cleared site, with six concrete circles, where the towers once stood.
- There is a sub-station to the South of the former power station.
- The River Don runs North-South on the map.
- Barnby Dun is the village to the East of the River Don.
Because of the towers, I’m unsure of the date of the map. Are Google’s maps ten years old?
The site certainly has the three most important things; location, location and location.
I suspect too, that large pieces of equipment could be floated in by barge.
The Type Of Storage
The press release just talks of a 2.8 GWh battery, but what type is it?
Lithium-Ion
This section in Wikipedia gives details of the world’s largest lithium-ion grid batteries.
- At 2.8 GWh the Thorpe Marsh battery would be bigger than any lithium-ion batteries, that are currently in operation, anywhere in the world.
- It would also be the third largest lithium-ion battery in the world, under development.
- It’s up there with a smaller-scale pumped storage hydro-electric power station like Ffestiniog power station.
I suspect that this battery might not be lithium-ion but one of the newer technologies.
Gravitricity
I suspect that a Gravitricity battery would be too small.
Highview Power
On the Projects page of the Highview Power web site, there is a list of their UK projects.
One project is headlined Yorkshire, UK and it is described like this.
Highview Power’s second commercial renewable energy power station in the UK is a 200MW/2.5GWh facility in Yorkshire. This is the first of 18 sites for UK wide deployment strategically located to benefit from the existing transmission infrastructure.
Could this 2.5 GWh project be the 2.8 GWh battery planned for Thorpe Marsh?
300 MWh is not a big difference between friends.
A Meeting About The Power Station
This article on the Doncaster Free Press is entitled Plans For Former Thorpe Marsh Power Station To Be Turned Into Green Energy Hub.
The article gives a lot of useful information and says this about the meeting.
The launch of the plan will take place with a surgery in Barnby Dun Parish Hall, Wednesday 2 November, 2pm-7:30pm.
I shall be going to have a look on the 2nd. Would anybody care to join me?
The article does have an artists’s impression of the battery, but it is a stock image of a series of lithium-ion batteries, that came from the Banks Group press release.
New South Wales Plans Three Batteries
This article on Energy Storage News is entitled Shell Battery Project In New South Wales Would Add 1GWh Energy Storage To Growing Market.
The three batteries are.
- Shell – 500MW/1,000MWh BESS project in Wellington, in Central West NSW.
- Waratah Super Battery 700MW/1,400MWh transmission system “shock absorber”
- A proposed 500MW/2,000 MWh BESS from energy generator-retailer EnergyAustralia.
Note.
- All batteries appear to be lithium ion.
- This gives a total output of 1.7 GW and a total storage capacity of 4.4 GWh.
- The NSW government is targeting 12GW of renewable energy capacity by 2030.
- 3 GW of utility-scale wind and solar in development, construction, or already in operation, in the state.
The state seems to be making a good start.
Q&A: What does ‘Subsidy-Free’ Renewables Actually Mean?
The title of this post, is the same as that of this article on Carbon Brief.
This is the first paragraph.
Recent announcements in the UK and across the rest of Europe seem to be ushering in a new era of “subsidy-free” renewables, which can be deployed without government support.
The article gives a detailed explanation and is a must-read.
BayWa r.e. Unveils Subsidy-Free Floating Wind Project Offshore Portugal
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the first paragraph.
BayWa r.e. has officially applied to secure the rights for an exclusive use of the seabed for a commercial-scale floating offshore wind project in Portugal, which the company said will be the first subsidy-free floating wind farm in the world.
Note.
- BayWa are a German company headquartered in Munich.
- The windfarm will have a 600 MW capacity in total, in a dedicated zone off the coastline of Viana do Castelo.
- It will be a floating wind farm.
- Viana do Castelo is situated at the mouth of the Lima River and is about 74 km. to the North of Porto.
But surely the most significant fact about this project is that it is subsidy-free.
BayWa And Subsidy-Free Wind Farms
This page on the BayWa web site is entitled BayWa r.e. Sells UK’s First Subsidy-Free Wind Farm.
This is the first paragraph.
BayWa r.e. has reached a milestone for itself and the UK renewable energy sector with the completion and sale of the country’s first subsidy-free windfarm to James Jones & Sons Ltd and London-based specialist asset manager, Gresham House Asset Management.
Note.
- This is the first time, I’ve seen Gresham House associated with wind farms.
- BayWa appear to have a fifteen year agreement with Tesco for the generated electricity.
The whole page is a must read.
Conclusion
Does this mean, that we will be seeing subsidy-free floating wind farms around the UK?
Get the engineering, manufacturing and financial support right for floating wind farms in the UK and wind farms could be bumper-to-bumper around these islands.
Plans Emerge For 8 GW Of Offshore Wind On Dogger Bank
Wikipedia has an entry, which is a List Of Offshore Wind Farms In The United Kingdom.
The totals are worth a look.
- Operational – 13279 MW
- Under Construction – 4125 MW
- Proposed Under The UK Government’s Contracts For Difference Round 3 – 2412 MW
- Proposed Under The UK Government’s Contracts For Difference Round 4 – 7026 MW
- Exploratory Phase, But No Contract for Difference – Scotland – 24,826 MW
- Exploratory Phase, But No Contract for Difference – England – 14,500 MW
Note.
- That gives a Grand Total of 66,168 MW or 66.168 GW.
- The government’s target is 50 GW of offshore wind by 2030.
- The typical UK power need is around 23 GW, so with nuclear and solar, we could be approaching three times the electricity generation capacity that we currently need.
The figures don’t include projects like Berwick Bank, Cerulean Wind, Norfolk Vanguard or Northern Horizons, which are not mentioned in Wikipedia’s list.
I regularly look at the list of wind farms in this Wikipedia entry and noticed that the number of Dogger Bank wind farms had increased.
They are now given as.
- Dogger Bank A – 1200 MW – Completion in 2023/24
- Dogger Bank B – 1200 MW – Completion in 2024/25
- Dogger Bank C – 1200 MW – Completion in 2024/25
- Dogger Bank D – 1320 MW – No Completion Given
- Dogger Bank South – 3000 MW – No Completion Given
Note, that gives a Grand Total of 7920 MW or 7.920 GW.
This article on offshoreWIND.biz is entitled BREAKING: SSE, Equinor Plan 1.3 GW Dogger Bank D Offshore Wind Project.
It was published on the October 6th, 2022 and starts with this summary.
SSE Renewables and Equinor are looking into building what would be the fourth part of Dogger Bank Wind Farm, the world’s largest offshore wind farm, whose three phases (A, B and C) are currently under construction. Surveys are now underway at an offshore site where the partners want to develop Dogger Bank D, which would bring Dogger Bank Wind Farm’s total capacity to nearly 5 GW if built.
Obviously, there are a few ifs and buts about this development, but it does look like SSE Renewables and Equinor are serious about developing Dogger Bank D.
More Dogger Bank Gigawatts for UK As RWE Moves Forward With Two 1.5 GW Projects
This subheading describes, the 3 GW wind farm, that I listed earlier as Dogger Bank South.
These three paragraphs describe the projects.
RWE is now moving forward with two new offshore wind farms in the Zone, each with a 1.5 GW generation capacity, after the company obtained approval from the UK Secretary of State for Business, Energy and Industrial Strategy (BEIS) to enter into an Agreement for Lease with The Crown Estate this Summer, following the Round 4 leasing process.
The wind farms will be built at two adjacent sites located just southwest of the Dogger Bank A offshore wind farm and are dubbed Dogger Bank South (DBS) East and Dogger Bank South (DBS) West.
RWE has also started with geophysical seabed surveys within the wind turbine array areas for its two new projects.
It appears that they have already got the leasing process started.
When Will Dogger Bank D And Dogger Bank South Be Operational?
Consider.
- In How Long Does It Take To Build An Offshore Wind Farm?, showed that a lot of offshore wind farms have gone from planning permission to first operation in six years.
- I don’t think that there will be planning permission problems on the Dogger Bank.
- The two wind farms are a continuation of Dogger Bank A, B and C and the Sofia wind farms.
- A lot of the construction, would be more of the same.
With average luck, I can see Dogger Bank D and Dogger Bank South in full production before the end of 2028.
