Pumped Storage Development In Scotland
The title of this post, is the same as that of this article on International Water Power & Dam Construction.
It describes and gives the current status of the two large pumped storage hydroelectric schemes under development in Scotland.
The 1.5 GW/30 GWh scheme at Coire Glass, that is promoted by SSE.
The Cruachan 2 scheme, that is promoted by Drax, that will upgrade Cruachan power station to 1.04 GW/7.2 GWh.
Note.
- Construction of both schemes could start in 2024, with completion in 2030.
- Both, SSE and Drax talk of a substantial uplift in employment during the construction.
- Both companies say that updated government legislation is needed for schemes like these.
The article is very much a must-read.
Conclusion
Welcome as these schemes are, given the dates talked about, it looks like we will need some other energy storage to bridge the gap until Coire Glas and Cruachan 2 are built.
Will Highview Power step forward with a fleet of their 2.5 GW/30 GWh CRYOBatteries, as was proposed by Rupert Pearce in Britain Will Soon Have A Glut Of Cheap Power, And World-Leading Batteries To Store It.
- The site needed for each CRYOBattery could be smaller than a football pitch.
- In Could A Highview Power CRYOBattery Use A LNG Tank For Liquid Air Storage?, I came to the conclusion that a single LNG tank could hold a lot of liquid air.
- The storing and recovery of the energy uses standard turbomachinery from MAN.
- Highview Power should unveil their first commercial system at Carrington near Manchester this year.
I am sure, that when they get their system working, they could build one in around a year.
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.
- The town of Dunbar is outlined in red.
- The yellow line running diagonally across the map is the A1 road.
- 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.
- Torness nuclear power station at the top of the map.
- The A1 road running across the map.
- The East Coast Main Line to the South of the A1.
- 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.
- Innerwick Castle is in the North-West corner of the map.
- 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.
Hornsea 2, The World’s Largest Windfarm, Enters Full Operation
The title of this post, is the same as that of this press release from Ørsted.
These are the first three paragraphs, which outline the project.
The 1.3GW project comprises 165 wind turbines, located 89km off the Yorkshire Coast, which will help power over 1.4 million UK homes with low-cost, clean and secure renewable energy. It is situated alongside its sister project Hornsea 1, which together can power 2.5 million homes and make a significant contribution to the UK Government’s ambition of having 50 GW offshore wind in operation by 2030.
The Hornsea Zone, an area of the North Sea covering more than 2,000 sq km, is also set to include Hornsea 3. The 2.8GW project is planned to follow Hornsea 2 having been awarded a contract for difference from the UK government earlier this year.
Hornsea 2 has played a key role in the ongoing development of a larger and sustainably competitive UK supply chain to support the next phase of the UK’s offshore wind success story. In the past five years alone, Ørsted has placed major contracts with nearly 200 UK suppliers with £4.5 billion invested to date and a further £8.6 billion expected to be invested over the next decade.
Note.
- Hornsea1 was the previous largest offshore wind farm.
- The first three Hornsea wind farms, could have a total output of over 5 GW.
- There is a possible Hornsea 4, that may be in the pipeline!
Will Hornsea 3 take the crown from Hornsea 2, when it is commissioned in 2027?
Where Are The Magnificent Eighteen?
In the two classic Japanese and American films of the fifties, there were seven saviours, who worked together.
This page on the Highview Power web site talks about their proposed CRYOBattery in Yorkshire, where this is said.
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.
As the UK’s energy problem is much worse than the problems in the films, perhaps we need more saviours.
In this article on the Telegraph, which is entitled Britain Will Soon Have A Glut Of Cheap Power, And World-Leading Batteries To Store It, Rupert Pearce, who is Highview’s chief executive, is quoted as saying the following.
Highview is well beyond the pilot phase and is developing its first large UK plant in Humberside, today Britain’s top hub for North Sea wind. It will offer 2.5GW for over 12 hours, or 0.5GW for over 60 hours, and so forth, and should be up and running by late 2024.
Further projects will be built at a breakneck speed of two to three a year during the 2020s, with a target of 20 sites able to provide almost 6GW of back-up electricity for four days at a time, or whatever time/power mix is optimal.
Is this Humberside CRYOBattery, the one on the web site described as in Yorkshire? It’s certainly in the old East Riding.
In Highview Power’s Plan To Add Energy Storage To The UK Power Network, I came to the conclusion, that the Humberside CRYOBattery will most likely be built near Creyke Beck substation, which is close to Cottingham.
- Dogger Bank A, Dogger Bank B and Hornsea 4 offshore wind farms will all be connected to the Creyke Beck substation.
- These wind farms have a total capacity of 3.4 GW.
- The Humberside CRYOBattery, now looks to have a maximum output of 2.5 GW.
- It looks like the Humberside CRYOBattery would be a well-matched backup to the three planned wind farms and perhaps even a few more turbines.
Building the Humberside CRYOBattery at Creyke Beck substation would appear to be a sensible decision.
We Only Have Half A Story
It looks like we’ve only got half a story, with a lot of detail missing.
- Will there be eighteen or twenty of Highview Power’s CRYOBatteries?
- Will they have a power output of 400 MW or nearly 6 GW for four hours?
- Will they have a storage capacity of 2.5 GWh or 30 GWh?
- Is the web site or the CEO correct?
- Have Highview Power and National Grid signed a deal for the next few CRYOBatteries?
I am expecting to see a big press statement at some time, perhaps even in the next few days, that will clear everything up.
If it was me, I would invite the new Prime Minister to the opening of the Carrington CRYOBattery and make the statement there.
The joint publicity could be equally valuable to both the Prime Minister and Highview Power.
Putin Burns $10m Of Gas A Day In Energy War With The West
The title of this post, is the same as that of this article in The Times.
This is the first paragraph.
Russia is burning off an estimated $10 million of natural gas a day from a single plant, leading to accusations that President Putin is deploying his country’s vast energy reserves as a weapon against Europe.
It just showed the sort of idiot we’re dealing with!
- He doesn’t care about the planet.
- He’s effectively burning his country’s cash reserves.
- He’s spurring Western engineers on, to on the one hand find ways to beat him and on the other to find ways to make our gas go further, so we don’t need to buy his bloodstained gas.
- If he thinks, that he might provoke a war with Finland, I suspect the Finns are too bright for that.
They’ll be waiting and if the Russian Army should invade, they’ll get the kicking of a lifetime, just like Stalin’s thugs did in the Winter War of 1939-1940.

Prysmian Completes HVDC Submarine Cable Testing
The title of this post, is the same as that of this article on renews.biz.
The article has this sub-heading.
The ‘first’ 525kV extruded wire can increase maximum transmission capacity up to more than 2.5GW.
This paragraph gives the implications of this new maximum transmission capacity.
This will enable a massive increase of the maximum transmission capacity of bi-pole systems up to more than 2.5GW, which is more than double the value achieved with 320kV DC systems currently in service, Prysmian said.
As in the future we will have many more large offshore wind farms in the UK, this surely must mean that we will find connecting them up a lot easier.
Should The World Call A Halt To Large Nuclear Power Stations?
When I left Liverpool University in the 1960s with an engineering degree, my fellow graduates and myself felt that nuclear power would be a sensible way to provide the electricity we need. Aberfan and other disasters had ruined coal’s reputation and not one of my colleagues joined the National Coal Board.
Over the intervening years, nuclear power has suffered a greater proportion of adverse events compared to other forms of electricity generation.
Large nuclear has also suffered some of the largest time and cost overruns of any energy projects.
My optimism for nuclear power has declined, although I do hope and feel, that small modular factory-built reactors, like those proposed by Rolls-Royce and others, might prove to be as reliable and economic as gas-fired, hydro-electric and tidal power stations, or solar and wind farms.
The smaller size of an SMR could be advantageous in itself.
- Smaller factory-built power stations are more likely to be built on time and budget.
- The amount pf nuclear material involved is only about twenty percent of that of a large nuclear station.
- A smaller site would be easier to protect from terrorists and Putinistas.
- Would the risk of a serious accident be reduced?
- SMRs would be less of a blot on the landscape.
- SMRs would not need such a high-capacity grid connection.
- An SMR integrated with a high temperature electrolyser could be the easiest way to generate hydrogen for a large customer like a steelworks.
Overall, I believe an SMR would be involve less risk and disruption.
Zaporizhzhya
Zaporizhzhya is probably the last straw for large nuclear, although the incident isorchestrated by an evil dictator, who is much worse, than any of James Bond’s cruel adversities.
I doubt Putin would get the same leverage, if Zaporizhzhya were a gas-fired or hydroelectric power station.
Conclusion
I feel, the world must seriously question building any more large nuclear power stations.
New Octopus Energy Makes First Investment To Develop UK’s Largest Battery
The title of this post, is the same as that of this article on Renewable Energy Magazine.
This is the first paragraph.
Octopus Energy Group has launched its new renewables fund Octopus Energy Development Partnership (OEDP) which has just made its debut investment in renewables developer Exagen to build new green energy and rapidly grow the UK’s energy storage capacity.
These three paragraphs outline the deal with Exagen.
This latest multi-million pound deal sees OEDP take a 24 percent stake in Exagen, which is working on large-scale solar and battery facilities, partnering with farmers, landowners and local communities to build projects that help bring energy security.
This deal includes the option to purchase one of the UK’s largest batteries at 500 MW/1 GWh located in the Midlands, England, scheduled to be operational by 2027. This standalone battery would be the UK’s largest, and with the capacity to export the equivalent electricity usage of 235,000 homes in a single day. Batteries provide grid-balancing services by storing cheap green energy when it is abundant, and releasing it when it is needed.
As part of the agreement, OEDP has also acquired three solar farms with batteries on-site in the Midlands and North East of England, which Exagen is currently developing. The solar farms have a combined capacity of approximately 400 MW. Exagen already has 2 GW of solar and battery storage projects in their pipeline, which Octopus will be able to invest in once they’re ready to build.
I am intrigued about the 500 MW/1 GWh battery!
Will it be lithium-ion?
The largest lithium-ion battery in the world is currently the 400 MW/1.6 GWh battery at Moss Landing Power Plant in California, which offers more storage capacity, but less output than Exagen’s proposed battery.
Exagen’s battery needs to be operational by 2027, which means that there is almost five years for an alternative technology to be thoroughly tested.
Highview Power say this about their proposed CRYOBattery in Yorkshire, on their web site.
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.
A battery similar to Highview’s proposed battery in Yorkshire, would surely be big enough.
Exagen’s battery could be one of the eighteen mentioned on Highview Power’s web site.
As Highview are currently building their first commercial system at Carrington in Manchester and hope to commission it this year, there should be enough time to debug the design.
But there are other companies, who may have the capability to build a large enough battery in the timescale.
On the other hand, lithium-ion would be the conservative choice.
Three Shetland ScotWind Projects Announced
The title of this post, is the same as that of this press release on Crown Estate Scotland.
These three paragraphs outline how the leases were allocated.
Three projects will be offered seabed agreements for offshore wind projects following Crown Estate Scotland’s ScotWind clearing process.
The announcement comes as an offshore wind supply chain summit is held in Aberdeen today (22 August) with Sir Ian Wood, chaired by Michael Matheson MSP, Cabinet Secretary for Energy, and including a keynote address by First Minister Nicola Sturgeon MSP.
Clearing saw the ‘NE1’ area east of Shetland made available for ScotWind applicants who met the required standards but who did not secure their chosen location earlier in the leasing process.
I think it was good idea to offer these leases to those bidders that failed to get a lease, the first time around, despite meeting the standards.
- Would it encourage bidders, if they knew that after the expense of setting up a bid, that if they failed, they could have another chance?
- It must also save the Scottish Government time and money checking out bidders.
- How many times have you interviewed several applicants for a job and then found jobs for some of those, that you didn’t choose for the original job?
Let’s hope the philosophy has generated some good extra contracts.
This map from Cross Estate Scotland shows all the contracts.
Note the three new leases numbered 18, 19 and 20 to the East of Shetland, in the North-East corner of the map.
Their details are as follows.
- 18 – Ocean Winds – 500 MW
- 19 – Mainstream Renewable Power – 1800 MW
- 20 – ESB Asset Development – 500 MW
Note.
All are floating wind farms.
- Ocean Winds is a Spanish renewable energy company that is developing the Moray West and Moray East wind farms.
- Mainstream Renewable Power appear to be a well-financed and ambitious company, 75 % owned by Aker.
- ESB Energy appear to be an experienced energy company owned by the Irish state, who operate several wind farms and Carrington gas-fired power station in the UK.
2.8 GW would appear to be a generous second helping.
Ocean Winds and Mainstream Renewable Power
This web page on the Ocean Winds web site, is entitled Ocean Winds Designated Preferred Bidder For Seabed Leases For 2.3 GW Of Floating Projects East Of Shetland, Scotland, contains several snippets of useful information.
- Crown Estate Scotland announced the result of ScotWind Leasing round clearing process, awarding Ocean Winds with two seabed leases for floating offshore wind projects: a 1.8 GW capacity site with partner Mainstream Renewable Power, and another 500 MW capacity site, east of the Shetland Islands.
- Ocean Winds’ international portfolio of projects now reaches 14.5 GW of gross capacity, including 6.1 GW in Scotland.
- Floating wind turbines for the two adjacent sites are confirmed, because of the water depth.
- The partners are committed to developing floating offshore wind on an industrial scale in Scotland, generating local jobs and opportunities in Scotland and the Shetland Islands.
- From the picture on the web page, it looks like WindFloat technology will be used.
- Ocean Winds developed the WindFloat Atlantic project.
Ocean Winds appear to want to go places.
The Shetland HVDC Connection
The Shetland HVDC Connection will connect Shetland to Scotland.
- It will be 160 miles long.
- It will have a capacity of 600 MW.
- It is estimated that it will cost more than £600 million.
- It will allow the 66MW Lerwick power station to close.
- It will be completed in 2024.
I have a feeling that all these numbers don’t add up to a sensible answer.
Consider.
- The three offshore wind farms can generate up to 2800 MW of green electricity.
- With a capacity factor of 50 %, an average of 1400 MW of electricity will be generated.
- The Viking onshore wind farm on Shetland could generate up to 450 MW.
- More wind farms are likely in and around Shetland.
- Lerwick power station can probably power most of the Shetland’s needs.
- Lerwick power station is likely to be closed soon.
- Sullum Voe Terminal has its own 100 MW gas-turbine power station.
- Load is balanced on Shetland by 3MWh of advanced lead-acid batteries.
- Lerwick has a district heating scheme.
If we assume that Shetland’s energy needs are of the order of a few hundred MW, it looks like at times the wind farms will be generating more electricity, than Shetland and the Shetland HVDC Connection can handle.
Various plans have suggested building electrolysers on Shetland to create hydrogen.
Conversion of excess electricity to hydrogen, would have the following advantages.
- The hydrogen could be used for local heavy transport and to replace diesel.
- Hydrogen could be used to fuel a gas turbine back-up power station, when needed.
- Hydrogen could be used for rocket fuel, if use of Shetland as a Spaceport for launching satellites takes off.
Any excess hydrogen could be exported to the rest of the UK or Europe.
Stockport Hydro
I hadn’t heard of Stockport Hydro, until there was a report about it on BBC Radio 5.
This is the introductory paragraph.
Stockport Hydro, a renewable energy scheme at Otterspool Weir on the river Goyt near Marple, Stockport, is Greater Manchester’s first community-owned hydro-electric project. Our two Archimedes screws, Thunder and Lightning, have been operational since October 2012, generating renewable electricity which is fed into the National Grid. We are accredited to earn the Government’s Feed-in-Tariff and the Environment Agency has approved our operation to ensure no damage to the river’s eco-system and wildlife.
This Google Map shows the location of the Stockport Hydro.
Note.
- The weir crosses the River Goyt
- The Stockport Hydro is at the West end of the weir.
- The green Archimedean screws can be seen on the South side of the building.
How many other weirs could host a small hydroelectric power station like this?
