The Anonymous Widower

Ossian Floating Wind Farm Could Have Capacity Of 3.6 GW

The title of this post, is the same as that of this article on offshoreWIND.biz,

This is the first paragraph.

SSE Renewables, Marubeni Corporation, and Copenhagen Infrastructure Partners (CIP) have identified an increase in the potential overall project capacity for their Ossian floating wind project in Scotland from 2.6 GW to up to 3.6 GW.

It appears that surveys have shown that the wind farm can be bigger.

About The Name Ossian

This press release from SSE is entitled New Offshore Wind Farm To Take Name From Scottish Literature.

These three paragraphs explain the name and the partners behind the project.

A new wind farm project in Scotland is to take its name from an historic series of books which depict the epic quests of a third-century Scottish leader, following his adventures across rolling seas.

Ossian (pronounced ‘os-si-un’) from The Poems of Ossian is to be the name for the proposed new offshore wind farm across 858 km2 of seabed in waters off the east coast of Scotland.

The project will be delivered by the partnership of leading Scottish renewable energy developer, SSE Renewables, Japanese conglomerate Marubeni Corporation (Marubeni) and Danish fund management company Copenhagen Infrastructure Partners (CIP).

I don’t think the three partners will have any difficulty raising the extra finance to expand the wind farm.

Where Is The Ossian Wind Farm?

This Crown Estate Scotland map shows the position of each of the Scotwind wind farms.

Note, that the numbers are Scotwind’s lease number in their documents.

The Ossian wind farm is numbered two.

At present, the South Eastern group of wind farms are as follows.

  • 1 – BP – Fixed – 2.9 GW
  • 2 – SSE – Floating – 2.6 GW
  • 3 – Falck – Floating – 1.2 GW
  • 4 – Shell – Floating – 2.0 GW
  • 5 – Vattenfall – Floating – 0.8 GW
  • 6 – DEME – Fixed – 1.0 GW

This totals to 10.5 GW, which would be 11.5 GW, if the capacity of Ossian is increased.

Will Ossian And Nearby Wind Farms Be Developed As A Co-Operation?

The six companies involved in this group of wind farms, are all experienced developers of wind farms or oil and gas fields.

They also come from all around the world, so I can see the best technology being employed on this group of wind farms.

Will Other Wind Farms In The Group Be Expanded?

The surveys at Ossian appear to have shown that the area is ideal for floating wind and this is enabling the expansion of the farm.

I wouldn’t be surprised to see some of the other wind farms be expanded.

I also feel that floating wind farms like Ossian, where it is likely that all the turbines on their floats are connected to a central substation, that could also be floating, may be a lot easier to expand.

Does Ossian Wind Farm Have A Web Site?

Not that Google can find, although ossianwindfarm.com appears to be under construction.

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.

  1. That gives a Grand Total of 66,168 MW or 66.168 GW.
  2. The government’s target is 50 GW of offshore wind by 2030.
  3. 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.

SSE Renewables Completes Acquisition Of European Renewable Energy Development Platform

The title of this post, is the same as that of this press release from SSE.

This paragraph introduces the deal.

SSE Renewables has completed the transaction with Siemens Gamesa Renewable Energy (SGRE) to acquire its existing European renewable energy development platform for a consideration of €580m.

I have a few thoughts.

Why Have Siemens Gamesa Sold Their European Renewable Energy Development Platform?

This article on Renewables Now is entitled Siemens Gamesa Wraps Up Sale Of 3.9-GW Wind Portfolio To SSE Renewables, gives a reason.

For the turbine maker, the sale represents one of the measures implemented to rein in profit losses quarter after quarter due to internal challenges, high costs and supply chain issues.

As with many things, it appears to be all about the money.

Can SSE Renewables Afford It?

Consider.

SSE seem to have found a Scottish magic money tree.

€580m is just small change.

What Projects Are Included In The Deal?

This is a paragraph from the press release.

The SGRE portfolio includes c.3.8GW of onshore wind development projects – around half of which is located in Spain with the remainder across France, Italy and Greece – with scope for up to 1.4GW of additional co-located solar development opportunities. Development of the portfolio of projects has continued to progress since the acquisition was announced in April, with additional opportunities identified and permits and grid connections advancing. Over 2GW of the total pipeline is considered to be at a secured stage, where a grid connection or land agreement has been secured or relevant permits granted.

Note.

  1. As an engineer, I note that there is no offshore wind, which surely is the renewable energy development with most risk and installation costs.
  2. SSE Renewables have a lot of experience of onshore wind, so delivering and financing the extra 3.8 GW, shouldn’t be a problem.
  3. The 1.4 GW of solar comes with the word co-located. Wind and solar together, perhaps with a battery must surely be a good investment in the sunnier climes of Europe.

It doesn’t look to me that SSE Renewables have bought a load of assets that no-one wants.

I do wonder thought, if Siemens Gamesa were having trouble progressing this large diverse portfolio of projects, due to a shortage of resources like money and engineers.

So are SSE finishing off a few projects and they can transfer a few engineers to these projects?

Are SSE Spreading The Risk?

SSE operate mainly in the UK and Ireland, so is adding Spain, France, Italy and Greece a good idea?

Of the four new countries, it’s unlikely that all will perform well, but a mixed portfolio is usually a good idea.

Will SSE Renewables  Buy Siemens Gamesa Turbines In The Future?

SSE Renewables seem to do an individual deal on each wind farm, as no one manufacturer dominates.

But now Siemens Gamesa may be more financially stable, perhaps they can get a better deal for the turbines they want.

Conclusion

I don’t think SSE Renewables have done a bad deal.

Berwick Bank Wind Farm Could Provide Multi-Billion Pound Boost To Scottish Economy And Generate Thousands Of Jobs

The title of this post, is the same as that of this press release from SSE.

This press release is all about numbers.

  • 307 turbines
  • 4.1 GW nameplate capacity
  • 5 million homes will be powered
  • 8 million tonnes of carbon dioxide avoided
  • Up to £8.3 billion to the UK economy
  • 4650 potential jobs in Scotland
  • 9300 potential jobs in the UK

These are all large figures.

This map from SSE shows the location of the wind farm.

The press release says this about connections to the grid.

Berwick Bank has secured a grid connection at Branxton, near Torness, in East Lothian. A second grid connection will be required for the project, which has been determined as Blyth, Northumberland.

Note, that Torness is the site of Torness nuclear power station.

  • It has a nameplate capacity of 1.29 GW.
  • It is scheduled to be shutdown in 2028.

This Google Map shows the coast between Dunbar and Torness nuclear power station.

Note.

  1. The town of Dunbar is outlined in red.
  2. The yellow line running diagonally across the map is the A1 road.
  3. Torness nuclear power station is in the South-East corner of the map to the North of the A1.

This second Google Map shoes an enlargement of the South-East corner of the map.

Note.

  1. Torness nuclear power station at the top of the map.
  2. The A1 road running across the map.
  3. The East Coast Main Line to the South of the A1.
  4. Innerwick Castle in the South-West corner of the map.

This Google Map shows the location of Branxton substation in relation to Innerwick Castle.

Note.

  1. Innerwick Castle is in the North-West corner of the map.
  2. Branxton substation is in the South-East corner of the map.

I estimate that the distance between Torness nuclear power station and Branxton substation is about five kilometres. The cable appears to be underground.

I have some thoughts.

Will The Connection Between Berwick Bank Wind Farm And Branxton Substation Be Underground?

If SSE follows the precedent of Torness nuclear power station, it will be underground.

Or will they use T-pylons?

This page on the National Grid web site is entitled What’s A T-Pylon And How Do We Build Them?.

From an engineering point of view, I suspect T-pylons could be used, but aesthetics and local preference may mean the cable is underground.

It should be noted that Torness nuclear power station will be shutdown in 2028. So will the current underground cable for the nuclear power station be repurposed after shutdown for the Berwick Bank wind farm?

This would mean, that the Southern connection cable to Blyth could be built first to support the first turbines erected in the wind farm.

When Will Berwick Bank Wind Farm Be Commissioned?

This page on the Berwick Bank wind farm web site is a briefing pack on the project.

The page gives construction and commission dates of 2026-2030.

Will There Be A Battery At Torness?

As we are talking about the latter half of the current decade for completion of the Berwick Bank wind farm, I believe that a substantial battery could be installed at Torness to smooth the output of the wind farm, when the wins isn’t blowing at full power.

One of Highview Power’s 2.5 GW/30 GWh CRYOBatteries could be about the right size if it has been successfully developed, but I am sure that other batteries will be of a suitable size.

If there is a case for a battery at Torness, there must surely be a case for a battery at Blyth.

Will Berwick Bank Wind Farm Be A Replacement For Torness Nuclear Power Station?

Consider.

  • Torness nuclear power station is shutting down in 2028.
  • Berwick Bank wind farm will be fully operational by 2030.
  • Berwick Bank wind farm could use a repurposed connection to Branxton substation, if the nuclear power station no longer needs it.
  • There is space on the Torness site for a large battery.

, it looks like Torness nuclear power station could be replaced by the larger wind farm.

The Creation Of The Coire Glas Monster

Loch Ness is probably most famous for the mythical monster, but it is about to be joined by a man-made monster of a different kind.

To the South-West of Loch Ness lies Loch Lochy.

This Google Map shows the South-Western part of the Great Glen, which runs diagonally across the Highlands from Fort William in the South-West to Inverness in the North-East.

Note.

  1. Fort Augustus in the North-East corner of the map, is at the South-West end of Loch Ness.
  2. In the South-West corner of the map, Loch Lochy can be seen.
  3. To the North-West of Loch Lochy, there are mountains.

This second Google Map shows Loch Lochy and the mountains.

SSE plan to create a pumped storage hydroelectric power station called Coire Glas.

  • Loch Lochy will be the lower reservoir.
  • The upper reservoir will be in the mountains to the North-West of the loch.
  • Energy will be stored by pumping water from the lower to the higher reservoir.
  • The power station will be able to provide 1.5 GW of electricity.
  • The upper reservoir will be able to store enough water to generate 30 GWh of electricity.

If that isn’t a monster of a power station, I don’t know what is! It has more than three times the storage capacity of both Dinorwig or Cruachan.

This article on Utility Week, which is entitled Inside £1bn Pumped Hydro Plans To ‘More Than Double’ Britain’s Electricity Storage, gives more details.

This is the sort of heroic engineering, that will defeat Vlad the Mad and his bloodstained gas.

SSE Issues €650M Green Bond As It Ramps Up Net Zero Acceleration Programme

The title of this post, is the same as that of this press release from SSE.

This is the first two paragraphs.

SSE plc has successfully issued a €650m 7-year green bond maturing 1 August 2029 at a coupon of 2.875 per cent.

Today’s issuance is SSE’s fifth green bond in six years and reaffirms its status as the largest issuer of green bonds from the UK corporate sector. It remains the only UK corporate to offer up multiple green bonds and this latest issuance brings SSE’s total outstanding green bonds to over £2.5bn.

It’s good to see that a company can raise money by issuing bonds to finance its green ambitions.

A few years ago, green investments were derided by many, but it now seems that SSE have made hem mainstream.

Will Coire Glas Start A Pumped Storage Boom In Scotland?

This article on Renewables Now is entitled SSE Gets Tenders For Construction Of 1.5-GW Pumped Hydro Scheme.

This is the first paragraph.

SSE Renewables said on Wednesday it has received tenders for the main construction works for the Coire Glas hydro pumped storage project with a capacity of up to 1.5 GW in the Scottish Highlands.

It then lists, the companies who have tendered for the project.

SE Renewables said the ITT has drawn global interest. The tenderers shortlisted for mechanical and electrical plant scope are a partnership between ANDRITZ HYDRO GmbH and Voith Hydro GmbH & Co KG, and GE Hydro France. The parties shortlisted for the civil engineering scope include three consortia and STRABAG UK Ltd. The consortia are made up of Bechtel Ltd, Acciona Construccion SA and Webuild SpA; BAM Nuttall Ltd, Eiffage Genie Civil SA and Marti Tunnel AG; and Dragados SA and BeMo Tunnelling UK Ltd.

It is an impressive list.

The article says that construction is to start in 2024. Other sources say the pumped storage project will have a storage capacity of 30 GWh, which will make it the largest pumped storage plant in the UK.

This press release from SSE Renewables is entitled Tenders Submitted For The Coire Glas Pumped Storage Scheme.

The press release contains this quote from the Project Director for Coire Glas; Ian Innes.

Receiving the tenders on schedule from the six short-listed tenderers is another significant milestone for the Coire Glas project and we are grateful for their continued interest in the project.

We are encouraged by the content of the tenders which now provides the Coire Glas project team with several options on how construction of the project could be undertaken. It is going to take some time to carefully consider and scrutinise the tenders thoroughly and we look forward to working with the tenderers as we endeavour to make our selection decision.

It appears that not only were the tenders received from quality companies, but that they contained options and ideas that could improve the project.

Coire Glas would appear to me to be a project, that is attracting the best companies and they could be putting their best workers on the project.

These are my thoughts.

The Potential For Pumped Storage Schemes In Scotland

There are at least five schemes under development or proposed in Scotland.

This page on the Strathclyde University web site, gives these figures for the possible amounts of pumped-storage that can be added to existing hydro schemes.

  • Errochty – 16
  • Glasgarnock – 23
  • Luichart – 38
  • Clunie – 40
  • Fannich – 70
  • Rannoch – 41
  • Fasnakyle – 78
  • Tummel – 38
  • Ben Lawers – 12
  • Nant – 48
  • Invermoriston – 22
  • Invergarry – 41
  • Quoich – 27
  • Sloy – 20

That is a total of 514 GWh or 620.3 GWh if you include the new storage, I listed above.

Scotland would appear to be land overflowing with large pumped storage possibilities and could provide the modern equivalent of milk and honey.

The Potential For Offshore Wind Power Schemes In Scotland

This is the first two paragraphs of this press release on the Crown Estate Scotland web site.

Crown Estate Scotland has today announced the outcome of its application process for ScotWind Leasing, the first Scottish offshore wind leasing round in over a decade and the first ever since the management of offshore wind rights were devolved to Scotland.

The results coming just months after Glasgow hosted the global COP26 climate conference show the huge opportunity that Scotland has to transform its energy market and move towards a net zero economy.

Some highlights are then listed.

  • 17 projects have been selected out of a total of 74 applications.
  • A total of just under £700m will be paid by the successful applicants in option fees and passed to the Scottish Government for public spending.
  • The area of seabed covered by the 17 projects is just over 7,000km2.
  • Initial indications suggest a multi-billion pound supply chain investment in Scotland
  • The potential power generated will move Scotland towards net-zero.

This map shows the location of each wind farm.

Note, that the numbers are Scotwind’s lease number in their documents.

Fixed Foundation Wind Farms

These are the six fixed foundation wind farms.

  • 1 – BP Alternative Energy Investments – 859 km² – 2.9 GW
  • 6 – DEME – 187 km² – 1.0 GW
  • 9 – Ocean Winds – 429 km² – 1.0 GW
  • 13 – Offshore Wind Power – 657 km² – 2.0 GW
  • 16 – Northland Power – 161 km² – 0.8 GW
  • 17 – Scottish Power Renewables – 754 km² – 2.0 GW

Adding up these fixed foundation wind farms gives a capacity of 9.7 GW in 3042 km² or about 3.2 MW per km².

Floating Wind Farms

These are the ten floating wind farms.

  • 2- SSE Renewables – 859 km² – 2.6 GW
  • 3 – Falck Renewables Wind – 280 km² – 1.2 GW
  • 4 – Shell – 860 km² – 2.0 GW
  • 5 – Vattenfall – 200 km² – 0.8 GW
  • 7 – DEME Concessions Wind – 200 km² – 1.0 GW
  • 8 – Falck Renewables Wind – 256 km² – 1.0 GW
  • 10 – Falck Renewables Wind – 134 km² – 0.5 GW
  • 11 – Scottish Power Renewables – 684 km² – 3.0 GW
  • 12 – BayWa r.e. UK  – 330 km² – 1.0 GW
  • 14 – Northland Power – 390 km² – 1.5 GW

Adding up the floating wind farms gives a capacity of 14.6 GW in 4193 km² or about 3.5 MW per km².

Mixed Wind Farms

This is the single wind farm, that has mixed foundations.

15 – Magnora – 103 km² – 0.5 GW

This wind farm appears to be using floating wind turbines.

These wind farms total up to 24.8 GW

I would expect that this is only a phase in the development of Scottish wind power, which will grow substantially over the next decade.

As I write this the UK is generating a total of 26.2 GW of electricity.

Backing Up The Wind Power

This wind power, which could grow up to well over 50 GW in Scotland alone.

But what do you do, when there is no wind?

Energy will need to come from batteries, which in Scotland’s case could be over 500 GWh of pumped storage.

Europe’s Powerhouse

It is not an unreasonable prediction, that we will continue to expand our wind farms to supply Europe with thousands of GWh of electricity and/or millions of tonnes of green hydrogen.

Conclusion

It is likely that we’ll see an upward increase of wind power in Scotland closely matched by a similar increase in pumped storage.

It is no wonder that the world’s largest and most experienced contractors were so keen to get the first big contract in Scotland’s new pumped storage boom.

They know a good thing, when they see it and after their experience with the Scotland’s oil boom in the last century, I doubt they are delaying their return.

SSE Renewables Launches 1.5GW Coire Glas Construction Tender

The title of this post, is the same as that of this article on renews.biz.

These are the first two paragraphs.

Hydro construction companies have been invited to submit tenders for construction of SSE Renewables’ proposed 1500MW pumped hydro storage scheme at Coire Glas, in Scotland.

Coire Glas, on the shores of Loch Lochy near Invergarry, would be the first large-scale pumped hydro storage scheme to be built in the United Kingdom for more than 30 years.

There appears to be global interest and six shortlisted bidders.

  • The ANDRITZ HYDRO and Voith Hydro partnership
  • The Bechtel, Acciona Construcción and Webuild S.p.A consortium
  • The BAM Nuttall, Eiffage Génie Civil and Marti Tunnel consortium
  • The Dragados and BeMo Tunnelling UK consortium
  • GE Hydro France
  • STRABAG UK

Bidders like these probably wouldn’t bother to get involved unless they knew that funding of the project was in place and it was pretty certain that the project will be constructed.

In World’s Largest Wind Farm Attracts Huge Backing From Insurance Giant, I talk about how Aviva are funding the Hornsea wind farm.

I believe, that insurance and pension companies like abrdn, Aviva and L & G could find a way of financing a scheme like Coire Glas.

Conclusion

It looks to me, that it’s almost certain that Scotland will get a 1.5GW/30 GWh pumped-storage system at Coire Glas.

Coire Glas could supply slightly more power than Sizewell B nuclear power station for twenty hours.

Now that’s what I call backup!
