SSE, Marubeni & CIP’s Floating Wind Farm In Scotland Could Have 270 Turbines And 6 Offshore Substations
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
SSE Renewables, Marubeni and Copenhagen Infrastructure Partners (CIP) have submitted the Environmental Impact Assessment (EIA) Scoping Report for the array area of their Ossian floating wind farm to Marine Scotland. According to the report, the wind farm could have up to 270 wind turbines and six offshore substations.
Ossian floating wind farm will be one of the world’s largest floating wind farms.
- If it sticks to 3.6 GW, 270 turbines will mean 13 MW turbines.
- 14 MW would be 3.8 GW and 15 MW would be 4 GW, with the same number of turbines.
- If they stick to 3.6 GW, this could be 257 x 14 MW or 240 x 15 MW turbines.
- Knowing ambitious engineers as I do and given that 15 MW turbines are on the way, I wouldn’t be surprised to see 15 MW turbines, to get the full 4 GW.
- According to this press release from Siemens Gamesa, they can make the turbine blades for their 15 MW turbines in Hull.
These two paragraphs outline the design possibilities.
For the floating wind turbine foundations, the consortium is considering either semi-submersible or Tension Leg Platform (TLP) structures and three mooring configurations; catenary, semi taut and taut mooring lines. Anchoring options currently under consideration include driven piles, and a number of different embedded anchor types, including suction piles, Drag Embedment Anchors (DEA) and VLA, with up to nine anchors required per foundation.
Floating foundations might not only be used for the wind turbines, but also for Ossian’s offshore substations.
When I look at a project like this, I also think of the project management possibilities.
- Will the six offshore sub-stations be positioned, so that as turbines are installed, they can be commissioned and start generating electricity?
- Is there software to optimise the order of installation?
- Has a specialist project management system been written for wind farms?
If you need a program to do analyse anything like that, buy me a drink and we’ll talk about it.
It’s about time, some of the algorithms in my brain were put to use.
The article also says this.
The 3.6 GW Ossian floating wind farm is planned to be up and running before the end of the decade.
My experience tells me, that if the right philosophy is used, that estimated date could be beaten.
It’s just that it is a project with so many complexities, that a proper mathematical model of its construction would yield benefits.
UK Confirms £205 Million Budget To Power More Of Britain From Britain
The title of this post, is the same as that of this press release from the Department of Energy Security And NetZero.
This is the sub title.
UK government confirms budget for this year’s Contracts for Difference scheme as it enters its first annual auction, boosting energy security.
These are the three bullet points.
- Government announces significant financial backing for first annual flagship renewables auction, boosting Britain’s energy security
- £170 million pledged for established technologies to ensure Britain remains a front runner in renewables and £10 million ring-fenced budget for tidal
- Scheme will bolster investment into the sector every year, delivering clean, homegrown energy as well as green growth and jobs
These are my thoughts.
First And Annual
The scheme is flagged as both first and annual!
Does this mean, that each Budget will bring forward a pot of money for renewables every year?
My father, who being a letterpress printer and a Cockney poet would say it did and I’ll follow his lead.
Two Pots
In Contracts for Difference Round 4, there were three pots.
- Pot 1 – Onshore Wind and Solar
- Pot 2 – Floating Offshore Wind, Remote Island Wind and Tidal Stream
- Pot 3 – Fixed Foundation Offshore Wind
This document on the government web site lists all the results.
For Contracts for Difference Round 5, there will be two pots, which is described in this paragraph of the press release.
Arranged across 2 ‘pots’, this year’s fifth Allocation Round (AR5) includes an allocation of £170 million to Pot 1 for established technologies, which for the first time includes offshore wind and remote island wind – and confirms an allocation of £35 million for Pot 2 which covers emerging technologies such as geothermal and floating offshore wind, as well as a £10 million ring-fenced budget available for tidal stream technologies.
It could be described as a two-pot structure with a smaller ring-fenced pot for tidal stream technologies.
Contract for Difference
There is a Wikipedia entry for Contract for Difference and I’m putting in an extract, which describes how they work with renewable electricity generation.
To support new low carbon electricity generation in the United Kingdom, both nuclear and renewable, contracts for difference were introduced by the Energy Act 2013, progressively replacing the previous Renewables Obligation scheme. A House of Commons Library report explained the scheme as:
Contracts for Difference (CfD) are a system of reverse auctions intended to give investors the confidence and certainty they need to invest in low carbon electricity generation. CfDs have also been agreed on a bilateral basis, such as the agreement struck for the Hinkley Point C nuclear plant.
CfDs work by fixing the prices received by low carbon generation, reducing the risks they face, and ensuring that eligible technology receives a price for generated power that supports investment. CfDs also reduce costs by fixing the price consumers pay for low carbon electricity. This requires generators to pay money back when wholesale electricity prices are higher than the strike price, and provides financial support when the wholesale electricity prices are lower.
The costs of the CfD scheme are funded by a statutory levy on all UK-based licensed electricity suppliers (known as the ‘Supplier Obligation’), which is passed on to consumers.
In some countries, such as Turkey, the price may be fixed by the government rather than an auction.
Note.
- I would trust the House of Commons Library to write up CfDs properly.
- As a Control Engineer, I find a CfD an interesting idea.
- If a generator has more electricity than expected, they will make more money than they expected. So this should drop the wholesale price, so they would get less. Get the parameters right and the generator and the electricity distributor would probably end up in a stable equilibrium. This should be fairly close to the strike price.
I would expect in Turkey with Erdogan as President, there are also other factors involved.
Renewable Generation With Energy Storage
I do wonder, if wind, solar or tidal energy, is paired with energy storage, this would allow optimisation of the system around the Contract for Difference.
If it did, it would probably mean that the generator settled into a state of equilibrium, where it supplied a constant amount of electricity.
Remote Island Wind
Remote Island Wind was introduced in Round 4 and I wrote about it in The Concept Of Remote Island Wind.
This was my conclusion in that post.
I must admit that I like the concept. Especially, when like some of the schemes, when it is linked to community involvement and improvement.
Only time will tell, if the concept of Remote Island Wind works well.
There are possibilities, although England and Wales compared to Scotland and Ireland, would appear to be short of islands.
This map shows the islands of the Thames Estuary.
Note.
- In Kent, there is the Isle of Sheppey and the Isle of Grain.
- Between the two islands is a large gas terminal , a gas-fired power station and an electricity sub-station connecting to Germany.
- In Essex, there is Canvey, Foulness and Potton Islands.
- There is also the site at Bradwell, where there used to be a nuclear power station.
If we assume that each island could support 200 MW, there could be a GW of onshore wind for London and perhaps a couple of SMRs to add another GW.
This map shows the islands around Portsmouth.
Note.
- Hayling Island is to the East of Portsmouth.
- Further East is Thorney Island with an airfield.
The Isle of Wight could be the sort of island, that wouldn’t welcome wind farms, although they do make the blades for turbines. Perhaps they should have a wind farm to make the blades even more green.
But going round England and Wales there doesn’t seem to be many suitable places for Remote Island Wind.
I do think though, that Scotland could make up the difference.
Geothermal Energy
This is directly mentioned as going into the emerging technologies pot, which is numbered 2.
I think we could see a surprise here, as how many commentators predicted that geothermal heat from the London Underground could be used to heat buildings in Islington, as I wrote about in ‘World-First’ As Bunhill 2 Launches Using Tube Heat To Warm 1,350 Homes.
Perhaps, Charlotte Adams and her team at Durham University, will capitalise on some of their work with a abandoned coal mine, that I wrote about in Exciting Renewable Energy Project for Spennymoor.
Timescale
This paragraph gives the timescale.
The publication of these notices mean that AR5 is set to open to applications on 30 March with results to be announced in late summer/early autumn 2023, with the goal of building upon the already paramount success of the scheme.
It does look like the Government intends this round to progress at a fast pace.
Conclusion
If this is going to be an annual auction, this could turn out to be a big spur to the development of renewable energy.
Supposing you have a really off-beat idea to generate electricity and the idea place in the world is off the coast of Anglesey.
You will certainly be able to make a bid and know like Eurovision, one auction will come along each year.
How Sideshore Technology Can Optimise The Layout Of Your Offshore Wind Farm By Applying State-Of-The-Art Algorithms
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Smarter offshore wind farm layouts will accelerate the energy transition
These paragraphs outline the problem.
Wind farm layout optimisation is the art of defining the optimal locations of wind turbines, infield cables and substation structures. It presents a golden opportunity to increase project value.
The academic community has done extensive research into numerical wind farm layout optimization, however, in real projects, it is hardly ever applied. Wind farm layout optimisation is complex because it is multidisciplinary. A wind farm development is typically split into work packages (turbine, foundations, cables, substation). The location of each turbine influences the project cost across the various work packages. While wake effects are important, other aspects need to be considered as well. For example, water depth affects the foundation size. Turbulence levels need to be restricted. And cables, seabed preparation, and soil conditions are often neglected, while they too can have a substantial impact on costs. Fully optimising the turbine positions requires not only insight into wake interactions and the cost drivers across all work packages but also a way of linking everything together.
My project management software writing experience would take a system like this further and use the output pf their system to create the project network for a project management system.
The possibilities then are endless.
Project Launches To Pair Offshore Wind With Sustainable Food Production
Note that it’s a little over a fortnight to April Fool’s Day!
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Win@Sea, a new collaboration between Vattenfall and Danish universities and companies, will investigate how to produce offshore wind power and sustainable food – all while improving the marine environment and biodiversity in the same marine area.
This is the first paragraph.
The partners will look into whether an offshore wind farm could simultaneously produce fossil-free electricity and sustainable food while also contributing positively to biodiversity in the same area.
But this report is not alone, in using the sea as a farm.
- Amazon Finances First-Ever Commercial-Scale Seaweed Farm Located Between Offshore Wind Turbines
- Brown Seaweed Could Remove 550 Million Tons Of Carbon
- The Plans For Giant Seaweed Farms In European Waters

It sounds to me like a case of great minds thinking alike.
RWE Conducting Seabed Habitat Survey For 3 GW Offshore Wind Farm In UK
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
RWE is performing a benthic survey off the northeast coast of the UK, where the company plans to build its 3 GW Dogger Bank South (DBS) Offshore Wind Farm.
That sounds like another 3 GW will soon be on its way.
In How Long Does It Take To Build An Offshore Wind Farm?, I said that six years from planning permission to commissioning was typical, so as this wind farm is applying for planning permission in 2024, I would expect that a completion date of 2030 is possible.
Dogger Bank Wind Farm Officially Celebrates Its Operations And Maintenance Base Opening
The title of this post is the same as that of this news item on the Dogger Bank wind farm web site.
These bullet points introduce the item.
- 150 guests and employees gathered to celebrate the official opening.
- The state-of-the-art base will be the hub for operations and monitor 5% of UK electricity from its control room.
- Over 400 long-term jobs have been created locally to support Operations and Maintenance from South Tyneside for the 35-year life of the wind farm.
- The world-class facility will be operated in line with the UK Green Building Council’s (UKGBC) Net Zero Carbon Buildings Framework
This Google Map shows the location of the base.
The red arrow indicates the base, which appears to be convenient for the North Sea.
This second Google Map shows a close up if the site.
There is a nice long quayside, which in the future could be large enough to assemble floating turbines.
This third image is a Google Map 3D visualisation of the site from across the Tyne.
The news item says this about the ownership and operation of the Dogger Bank wind farm.
Dogger Bank Wind Farm is a joint venture between SSE Renewables (40%), Equinor (40%) and Vårgrønn (20%). SSE Renewables is lead operator for the development and construction of Dogger Bank Wind Farm. Equinor will be lead operator of the wind farm on completion for its expected operational life of around 35 years.
Initially, the Port of Tyne base will operate and maintain these wind farms.
- Dogger Bank A – 1235 MW
- Dogger Bank B – 1235 MW
- Dogger Bank C – 1218 MW
This gives a total of 3688 MW.
Note.
- SSE Renewables and Equinor are also developing the 1500 MW Dogger Bank D wind farm.
- This would bring the total up to 5188 MW.
- RWE are also developing the 3000 MW Dogger Bank South wind farm.
Leases were signed for both the Dogger Bank D and Dogger Bank South wind farms in January 2023.
I doubt all of these wind farms will be operated and maintained from the Port of Tyne base, due to the different ownership of Dogger Bank South.
But, I do hope that the facility can be expanded to handle Dogger Bank D.
GE Developing 18 MW Haliade-X Offshore Wind Turbine
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
GE could soon join the list of wind turbine manufacturers who have passed the current 15 MW “threshold” by producing and/or announcing more powerful models. According to information recently shared with investors, the US-headquartered company is likely to climb up the offshore wind turbine output ladder, currently led by Chinese OEMs, with an up to 18 MW Haliade-X turbine.
Note.
- GE’s current largest turbine is a 14.7 MW example.
- GE are supplying the 3.7 GW of turbines for the Dogger Bank wind farms.
It does look like GE intend to put the Chinese in their place.
Welsh Government Greenlights Erebus Floating Offshore Wind Farm
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Welsh Government has granted consent for the country’s first floating offshore wind farm located 40 kilometres off the coast of Pembrokeshire
This is the first paragraph.
Project Erebus will feature seven next-generation 14 MW turbines on floating platforms, providing enough renewable energy to power 93,000 homes.
This near 100 MW project is the first in the Celtic Sea, where there 4 GW are to be installed in the next decade.
This is another paragraph.
Future phases of the development could realise an additional 20 GW of renewable energy, according to the Government.
Wales is not going to be short of energy!
Drax Moves Forward With 600MW Scottish Hydro Scheme
The title of this post, is the same as that of this article on reNEWS.BIZ.
This is the sub-heading.
Studio Pietrangeli has been appointed as owner’s engineer for the project
It looks like this 600 MW project, which will turn Drax’s 440 MW pumped storage hydroelectric power station into 1 GW power station, is finally on its way.
Reading about this project on the Internet, there are still some hurdles to be overcome before the power station is upgraded.
- Planning permission is needed.
- Both the UK and Scottish Governments need to give permission.
- Argyle and Bute Council are not totally behind the project.
My view as a Control Engineer, is that we need it to help balance the grid and allow wind power to play its full part.
Irish Green Hydrogen Could Be Europe’s Cheapest In 2030, Aurora Finds
The title of this post, is the same as that of this article on Renewables Now.
These two paragraphs outline the story.
Ireland could produce the cheapest green hydrogen in Europe by 2030, achieving a levelised cost of EUR 3.50 (USD 3.73) per kg under optimal conditions, Aurora Energy Research said on Tuesday.
This would be 8% below optimal production costs in Spain and 35% below those in Germany, with Ireland’s cost advantage driven by the country’s high wind speeds and rising grid congestion.
Aurora also sees the possibility of exports to Germany before 2030.
