Bilfinger Drives Highview Power’s Innovative Storage Project, Accelerating The Energy Transition

The title of this post, is the same as that of this press release from Bilfinger, who are a European multinational engineering and services company.

This is the first paragraph of the Wikipedia entry for Bilfinger.

Bilfinger SE (previously named Bilfinger Berger AG) is a European multinational company specialized in civil and industrial construction, engineering and services based in Mannheim, Germany.

Fifty years ago, I was playing a very small part in the designing of complex chemical plants for ICI. My part was mainly to check, the mathematics and dynamics for the designs, the engineers wanted to use.

The experience certainly left me with the belief, that to design a world-class chemical plant is not an easy process.

So if I was needing a complex chemical plant, I would call in the experts.

A Highview Power energy  storage system, may not be a chemical plant, but it shares many of the factors of chemical plants, waterworks and sewage plants. So building one, needs a company, with wide experience, which Bilfinger certainly appear to have.

This paragraph from the press release, summarises Bilfinger’s roll in Hghview Power’s Manchester project to create a 50 MW/300 MWh battery based on Highview’s proprietary long duration energy storage system.

The scope of Bilfinger’s services ranges from the procurement of steel to extensive plant construction services, including mechanical, electrical, instrumentation, insulation, painting and structural steel work, along with the overall management of all aspects of construction, including civil works and equipment installation. As principal contractor, Bilfinger is committed to ensuring the highest safety standards on site.

In UK Infrastructure Bank, Centrica & Partners Invest £300M in Highview Power Clean Energy Storage Programme To Boost UK’s Energy Security, I described how Highview Power had recruited high-class backers to fix the companies finances.

It looks like the Bilfinger deal to build the first system, is the last piece of the jigsaw and will see Highview Power on its way.

Where’s The Plan, Rishi?

In RWE Goes For An Additional 10 GW Of Offshore Wind In UK Waters In 2030, I detailed how RWE intended to add an extra 10 GW of offshore wind to the seas around the UK.

As our current offshore wind capacity is around 15 GW, another 10 GW would surely be very welcome.

My post also outlined H2ercules, which is Germany’s massive  project to create a hydrogen network to bring hydrogen to Southern Germany.

I also gave details of the hydrogen hub at Wilhelmshaven, which is being built by Uniper to feed H2ercules with green hydrogen from around the world.

I believe that some of this hydrogen for H2ercules will take a short trip across the North Sea from UK waters, after being created by offshore electrolysers.

Rishi Sunak’s Manifesto Speech – June 11

I also reported on Rishi Sunak’s Manifesto Speech, which he made on June 11th. This is an extract

This document on the Policy Mogul web site is entitled Rishi Sunak – Conservative Party Manifesto Speech – Jun 11.

These are three paragraphs from the speech.

We don’t just need military and border security. As Putin’s invasion of Ukraine has shown, we need energy security too. It is only by having reliable, home-grown sources of energy that we can deny dictators the ability to send our bills soaring. So, in our approach to energy policy we will put security and your family finances ahead of unaffordable eco zealotry.

Unlike Labour we don’t believe that we will achieve that energy security via a state-controlled energy company that doesn’t in fact produce any energy. That will only increase costs, and as Penny said on Friday there’s only one thing that GB in Starmer and Miliband’s GB Energy stands for, and that’s giant bills.

Our clear plan is to achieve energy security through new gas-powered stations, trebling our offshore wind capacity and by having new fleets of small modular reactors. These will make the UK a net exporter of electricity, giving us greater energy independence and security from the aggressive actions of dictators . Now let me just reiterate that, with our plan, we will produce enough electricity to both meet our domestic needs and export to our neighbours. Look at that. A clear, Conservative plan not only generating security, but also prosperity for our country.

It is now nine days since Rishi made that speech and I can’t remember any reports about an energy security policy, which he outlined in the last paragraph of my extract from his speech.

He particularly mentioned.

  • New gas-powered stations
  • Trebling our offshore wind capacity
  • Having new fleets of small modular reactors.

He also said we would have sufficient electricity to export to our neighbours. As I said earlier some of this energy will be in the form of hydrogen, which has been created by offshore electrolysers.

If we are exporting electricity and hydrogen to Europe, this is likely to have three effects.

  • An improvement in Europe’s energy security.
  • H2ercules will improve and decarbonise German industry, using UK hydrogen.
  • The finances of UK plc will improve.

It looks like there will be winners all round.

Rishi also said this, in his speech.

As Putin’s invasion of Ukraine has shown, we need energy security too.

The gas-powered stations, offshore wind farms and the fleets of small modular reactors, will be part of the equation.

But I believe, we need three other components to complete our energy security.

  • The upgrading of the National Grid.
  • The building of four x 2 GW interconnectors between Scotland and Eastern England.
  • Large amounts of energy storage.

Note.

  1. The Great Grid Upgrade and the four x 2 GW interconnectors are being planned.
  2. In Huge Boost To UK Supply Chain As National Grid Launches The Great Grid Partnership With Seven New Industry Partners, All United In The Drive To Deliver The Great Grid Upgrade, I describe how National Grid has setup the Great Grid Partnership to deliver the Great Grid Upgrade.
  3. In UK Infrastructure Bank, Centrica & Partners Invest £300M in Highview Power Clean Energy Storage Programme To Boost UK’s Energy Security, I describe how the big boys do a deal with Highview Power to create affordable batteries for the UK and the world.
  4. In Grid Powers Up With One Of Europe’s Biggest Battery Storage Sites, I describe how the very large Swardeston BESS is to be built near Norwich.
  5. In Mercia Power Response & RheEnergise Working Together To Build Long Duration Energy Storage Projects In The UK, I describe another UK-developed long duration energy storage system, which is now being planned.
  6. In National Grid Shares Proposals For Green Electricity Projects In Lincolnshire And West Norfolk, Needed To Boost Home-Grown Energy Supplies And Progress Towards Net Zero, I describe National Grid’s projects in the East of England.
  7. In UK ESO Unveils GBP 58 Billion Grid Investment Plan To Reach 86 GW of Offshore Wind By 2035, I show how we’re not that far away from 86 GW by 2035.
  8. In 400k For National Grid Innovation Projects As Part Of Ofgem Fund To Help Shape Britain’s Net Zero Transition, I describe how National Grid is using innovation to help target net-zero by 2035.
  9. In Iberdrola Preparing Two East Anglia Offshore Wind Projects For UK’s Sixth CfD Round, I describe how Iberdrola  is getting 1.7 GW ready for commissioning in 2026.
  10. In National Grid To Accelerate Up To 20GW Of Grid Connections Across Its Transmission And Distribution Networks, I describe how National Grid are accelerating the development of the electricity networks. 10 GW of battery storage is a collateral benefit.

These ten projects, most of which are financed and/or underway, would appear to be good foundations, on which to build the Great Grid Upgrade.

It looks to me, that National Grid, RWE, Centrica, Iberdrola and others, by just doing what comes naturally have offered the next government a road to a future.

It will be interesting, what gets said before the election.

UK Infrastructure Bank, Centrica & Partners Invest £300M in Highview Power Clean Energy Storage Programme To Boost UK’s Energy Security

The title of this post, is the same as that of this news item from Highview Power.

This is the sub-heading.

Highview Power kickstarts its multi-billion pound renewable energy programme to accelerate the UK’s transition to net zero in Carrington, Manchester.

These three paragraphs outline the investment.

Highview Power has secured the backing of the UK Infrastructure Bank and the energy industry leader Centrica with a £300 million investment for the first commercial-scale liquid air energy storage (LAES) plant in the UK.

The £300 million funding round was led by the UK Infrastructure Bank (UKIB) and the British multinational energy and services company Centrica, alongside a syndicate of investors including Rio Tinto, Goldman Sachs, KIRKBI and Mosaic Capital.

The investment will enable the construction of one of the world’s largest long duration energy storage (LDES) facilities in Carrington, Manchester, using Highview Power’s proprietary LAES technology. Once complete, it will have a storage capacity of 300 MWh and an output power of 50 MWs per hour for six hours. Construction will begin on the site immediately, with the facility operational in early 2026, supporting over 700 jobs in construction and the supply chain.

Note.

  1. The backers are of a high quality.
  2. The Carrington LDES appears to be a 50 MW/300 MWh battery.

It finally looks like Highview Power is on its way.

These are my thoughts on the rest of news item.

Centrica’s Involvement

This paragraph talks about Centrica’s involvement.

Energy leader Centrica comes on board as Highview Power’s strategic partner and a key player in the UK’s energy transition, supporting Carrington and the accelerated roll-out of the technology in the UK through a £70 million investment. The programme will set the bar for storage energy systems around the world, positioning the UK as the global leader in energy storage and flexibility.

I suspect that Centrica have an application in mind.

In Centrica Business Solutions Begins Work On 20MW Hydrogen-Ready Peaker In Redditch, I talk about how Centrica is updating an old peaker plant.

In the related post I refer to this news item from Centrica Business Systems.

This paragraph in the Centrica Business Systems news item, outlines Centrica’s plans.

The Redditch peaking plant is part of Centrica’s plans to deliver around 1GW of flexible energy assets, that includes the redevelopment of several legacy-owned power stations, including the transformation of the former Brigg Power Station in Lincolnshire into a battery storage asset and the first plant in the UK to be part fuelled by hydrogen.

As Redditch power station is only 20 MW, Centrica could be thinking of around fifty assets of a similar size.

It seems to me, that some of these assets could be Highview Power’s LDES batteries of an appropriate size. They may even be paired with a wind or solar farm.

Larger Systems

Highview Power’s news item, also has this paragraph.

Highview Power will now also commence planning on the next four larger scale 2.5 GWh facilities (with a total anticipated investment of £3 billion). Located at strategic sites across the UK, these will ensure a fast roll-out of the technology to align with UK LDES support mechanisms and enable the ESO’s Future Energy Scenario Plans.

Elsewhere on their web site, Highview Power say this about their 2.5 GWh facilities.

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.

So will the four larger systems have a 200MW/2.5GWh capacity?

They could, but 200 MW may not be an appropriate output for the location. Or a longer duration may be needed.

Highview Power’s design gives the flexibility to design a system, that meets each application.

Working With National Grid

Highview Power’s news item, also has this sentence.

Highview Power’s technology will also provide stability services to the National Grid, which will allow for the long-term replacement of fossil fuel-based power plants for system support.

Highview Power’s technology is also an alternative to Battery Energy Storage Systems (BESS) of a similar capacity.

How does Highview Power’s technology compare with the best lithium-ion systems on price, performance and reliability?

Curtailment Of Wind Farms

Highview Power’s news item, also has these two paragraphs.

This storage will help reduce curtailment costs – which is significant as Britain spent £800m in 2023 to turn off wind farms.

Highview Power aims to accelerate the roll-out of its larger facilities across the UK by 2035 in line with one of National Grid’s target scenario forecasts of a 2 GW requirement from LAES, which would represent nearly 20% of the UK’s long duration energy storage needs. By capturing and storing excess renewable energy, which is now the cheapest form of electricity, storage can help keep energy costs from spiralling, and power Britain’s homes with 24/7 renewable clean energy.

I can see several wind farms, that are regularly curtailed would have a Highview Power battery installed at their onshore substation.

Receently, I wrote Grid Powers Up With One Of Europe’s Biggest Battery Storage Sites, which described how Ørsted are installing a 300 MW/600 MWh Battery Energy Storage Systems (BESS) at Swardeston substation, where Hornsea Three connects to the grid.

I would suspect that the purpose of the battery is to avoid turning off the wind farm.

Would a Highview Power battery be better value?

What’s In It For Rio Tinto?

I can understand, why most companies are investing, but Rio Tinto are  a mining company. My only thought is that they have a lot of redundant holes in the ground, that cost them a lot of money and by the use of Highview Power’s technology, they can be turned into productive assets.

Collateral Benefits

Highview Power’s news item, also has this paragraph.

Beyond contributing to the UK’s energy security by reducing the intermittency of renewables, Highview Power’s infrastructure programme will make a major contribution to the UK economy, requiring in excess of £9 billion investment in energy storage infrastructure over the next 10 years – with the potential to support over 6,000 jobs and generate billions of pounds in value add to the economy. It will also contribute materially to increasing utilisation of green energy generation, reducing energy bills for consumers and providing significantly improved energy stability and security.

If Highview Power can do that for the UK, what can it do for other countries?

No wonder companies of the quality of Centrica, Rio Tinto and Goldman Sachs are investing.

Grid Powers Up With One Of Europe’s Biggest Battery Storage Sites

The title of this post, is the same as that of this article in The Times.

This is the sub-heading.

Orsted’s huge facility in Norfolk will store energy generated by its offshore wind farm

These three paragraphs give more details of the project.

The world’s largest developer of offshore wind farms is planning to build a vast battery storage facility near Norwich.

Orsted will install the energy storage system, which will be one of the largest in Europe, on the same site as the onshore converter station for its Hornsea 3 wind farm in Swardeston, Norfolk.

The project will store energy generated by Hornsea 3 when weather conditions are windy and when electricity supply exceeds demand so that it can be discharged later to help to balance the nation’s electricity grid.

Note.

  1. There is also a visualisation and a map.
  2. Tesla batteries will be used.
  3. The The battery will have an output of 300 MW, with a capacity of 600 MWh. So it is another two-hour BESS.
  4. It should be operational in 2026.
  5. The battery is on a 35-acre site.
  6. Cost is given as £8.5 billion, but that would appear to include the 2852 MW Hornsea 3 wind farm.

The BBC is reporting that local residents are worried about fire safety.

I have some thoughts of my own.

The Location Of The Swardeston Substation

This Google Map shows the location of the Swardeston substation, which will also host the Swardeston BESS.

Note.

  1. The East-West road is the A 47 Norwich by-pass.
  2. Norwich is to the North of the by-pass.
  3. Just to the left-centre of the map, the main A 140 road runs between Norwich and Ipswich, which has a junction with the A 47.
  4. The A 140 passes through the village of Dunston, which is to the East of the National Grid sibstation, which will host the connection to the Hornsea Three wind farm.

This second Google Map shows the A 140 in detail from the junction to the A 47 to the Swardeston substation.

Note.

  1. The Swardeston substation is on a substantial site.
  2. The Norwich to Tilbury transmission line will have its Northern end at Swardeston substation.
  3. Once the infrastructure is complete at Swardeston substation, Hornsea Three wind farm will be connected to the electricity infrastructure around London.

There would appear to be plenty of space at the site for all National Grid’s plans.

Capital Cost Compared To Big Nuclear

Hornsea Three is a 2852 MW wind farm, that will cost with the battery and a few extras £8.5 billion or around around £ 3 billion per gigawatt.

Hinckley Point C on the other hand will cost between £ 31-35 billion or £ 9.5-10.7 billion per gigawatt.

Conclusion

National Grid would appear to be using a BESS at Swardeston substation to improve the reliability and integrity of the Hornsea Three wind farm.

How many other big batteries will be placed, where large wind farms connect to the National Grid?

As an Electrical and Control Engineer, I certainly, believe that energy storage at major substations, is a proven way to improve the grid.

Recurrent Energy’s Middle Road Project Sold To Centrica

The title of this post, is the same as that pf this article on Solar Power Portal.

These are the first two paragraphs.

Recurrent Energy, a global solar and energy storage developer and a subsidiary of Canadian Solar, announced the sale of its 49.9 MWp Middle Road solar project in Harbury, Warwickshire, to Centrica Business Solutions. The subsidy-free project, slated for construction this summer, will commence operations in 2025.

The Middle Road project is just one piece of Recurrent Energy’s expanding UK pipeline, which boasts over 2.6 GWp of solar PV and 6.7 GWh of battery storage projects. This mirrors the broader trend of increased investment in UK solar. Indeed, Recurrent announced €1.3 billion of financing for EU and UK solar projects earlier this week.

This 49.9 MW solar project shows three ways to make money from a solar project.

The Developer

Recurrent Energy would appear to have developed the expertise to put together these solar farms and do all the legals and administration to connect them to the National Grid.

They obviously can show their financial backers, the cash flow, that the farms generates.

So if you’re good at building solar farms, I suspect you can develop a substantial pipeline of projects, each with their own case flow.

The Operator

Initially in the early days, Recurrent Energy will probably be the operator, so they can sort out any teething problems and build the financial profile of the site.

The Owner

But as at Middle Road, they may decide to cash in their investment.

Centrica have now taken over the ownership and they can operate the farm themselves or pay, Recurrent Energy a fee.

Note.

  1. Developer, operator and owner all have ways of making money from this solar farm.
  2. Developer and owner can use the solar farm, as an asset on which to raise money.
  3. Similar cash flows and inside probably apply to batteries and wind farms.

By buying, selling and updating the various assets, a financial operator, can use their assets to make money.

As Centrica are also an electricity supplier, they can probably suggest to developers, where a solar farm or battery-electric storage system is needed.

Are Centrica Developing A Pipeline Of Projects?

In Centrica Set For Solar Boost With Acquisition Of Two Projects In South-West England, I talked about how Centrica had acquired two projects in South-West England.

The Middle Road project is the third project that Centrica has purchased this year.

As a Control and Electrical Engineer, I know, that by careful management of the assets, Centrica can achieve the following.

  • Delivery of electricity to their customers at a competitive price.
  • If a battery is included in the local grid, higher supply reliability can be achieved.
  • Batteries also allow the local network to carry out other tasks, like frequency stabilisation.

The flexibility of the local network should allow other assets to be added.

Teesworks Joins Forces With NatPower On 1GW UK BESS

The title of this post, is the same as that of this article on Solar Power Portal.

These are the first two paragraphs.

Teesworks, the UK’s largest industrial zone, has revealed plans for a 1GW battery energy storage system (BESS) in partnership with renewables developer NatPower.

The project will be constructed over 50 acres of the Long Acres section of the 4500-acre Teesworks site. Construction costs are expected to total around £1 billion. While the main plan for the BESS is focused on renewable energy storage, the company also noted that the system could also support electric vehicle (EV) charging in the future.

The article then lists several large BESS projects, that are under development.

It also suggests that investment in batteries is in a healthy state.

Construction Under Way To Double Power Station Capacity At Centrica’s Brigg Energy Park

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

This is the sub-heading.

Four ultra-efficient engines have arrived at Centrica’s former combined cycle gas power station at Brigg, with construction work underway on an expansion of the peaking plant at the Lincolnshire site.

These three paragraphs give more details about the project.

The business is installing the four engines inside the former turbine hall at the power station, which was decommissioned in 2020, helping to create nearly 100MW of fast response assets capable of meeting demand when renewable generation is low.

The expanded power plant will be hydrogen-ready, and form part of a trial due to start in late 2024 to blend hydrogen into the gas, ramping up from a three per cent blend to 20 per cent, with a long term vision to move towards 100 per cent hydrogen and to deploy similar technology across all peaking plants.

Work at Brigg is expected to last around nine months and the plant will be fully operational in early 2025.

These are my thoughts.

Hydrogen Blend Operation

The second paragraph indicates that Centrica will be using Brigg power station to research the use of hydrogen blends.

Hydrogen blends could offer a way an easy way to cut hydrogen emissions, so it is good, that Centrica are researching their use in gas-fired power stations.

Brigg As A Peaking Plant

 

This paragraph from the press release, explains what Centrica means by a peaking plant.

Peaking plants only generate electricity when there’s high or peak demand for electricity, or when generation from renewables is too low to meet demand. Once connected to the grid, the engines will have the capacity to power 20,000 homes for a full day when required, which will maintain stability and deliver reliable power across the grid.

The second paragraph also says this.

A long term vision to move towards 100 per cent hydrogen and to deploy similar technology across all peaking plants.

Does this mean that all peaking plants will move to hydrogen-fired generation?

Brigg Redevelopment

This paragraph from the press release, outlines Centrica’s plans for Brigg power station.

Centrica is redeveloping the Brigg energy park which, once complete, will be home to a 50MW battery, commercial-scale hydrogen production using HiiROC technology (in which Centrica has a five per cent stake), and 100MW of gas peaking plant.

Note.

  1. I would assume that the battery, will be able to provide 50 MW for at least two hours, so the battery electric storage system (BESS) will be at least a 50 MW/100 MWh unit.
  2. The HiiROC technology is being developed on the other side of the Humber in Hull.
  3. HiiROC technology captures the carbon in the gas as carbon black, which has uses in its own right, in agriculture and tyre and other manufacturing.
  4. Both a battery and a gas peaking plant, will be used at Brigg to match generation with demand.

I wouldn’t be surprised that to use both a battery and a gas peaking plant, is the most efficient way to balance the renewable energy.

Hydrogen Production

The HiiROC technology that will be used at Brigg can extract hydrogen from a variety of sources including biomethane, chemical plant off gas or natural gas.

The HiiROC technology can be scaled to fit the application.

I feel that the versatility of the HiiROC technology, may result in using some unusual feeds to produce hydrogen.

As an example of the deployment of a small HiiROC system , one at a sewage works could provide hydrogen for the utility company’s vehicles.

The main use of the hydrogen would be to provide a clean fuel for the gas-fired peaking plant.

I also wouldn’t be surprised to see the hydrogen, sold and distributed to the local area, from an energy park, like Brigg.

Conclusion

Increasingly, backup for renewables will use a wide range of zero-carbon technologies.

Ameresco And Envision Energy To Deploy 624MWh UK BESS For Atlantic Green

The title of this post, is the same as that of this article on Energy Storage News.

These three paragraphs describe the project.

Developer-operator Atlantic Green has enlisted system integrator Ameresco and clean energy manufacturer Envision Energy for a 300MW/624MWh BESS project in the UK.

The Cellarhead battery energy storage system (BESS) project will be connected to National Grid’s Cellarhead substation in the West Midlands and have a maximum energy capacity of 624MWh. Construction is expected to begin this year, with final connection to the grid slated for the end of 2026.

The deal between the parties is worth £196.5 million (US$250 million). Ameresco will build the project via an engineering, procurement and construction (EPC) and operation & maintenance (O&M) agreement while Envision Energy will supply the BESS units.

Note.

  1. It is another battery, that can provide full power for two hours.
  2. It is another battery, that is located near to one of National Grid’s substations.

As batteries seem to be made by different companies, it looks to me, that National Grid are possibly checking out, which batteries are best.

Frederick Snow & Partners, The Severn Barrage And Harold Wilson’s Government

In the 1970s, for a few weeks, I did a project management consultancy on the new Belfast international Airport.

I am sure they felt I was more experienced than I was, because they gave me a report on their proposal to barrage the River Severn and asked me to comment.

As consultant engineers, who had designed Gatwick Airport, the main feature of the barrage, was a central spine in the River with a major two-runway airport on top.

  • The runways would have pointed into the prevailing wind, which would have made take-offs and landings, efficient and safe.
  • A few minutes and perhaps five percent of fuel would have been saved on flights to the West.
  • The central spine would have divided the river into two parallel lakes; a high lake and a low one.
  • I seem to remember, that the high lake was on the Welsh side.

At the Western end of the lake and the spine, there would have been a barrage.

  • Sluice gates would have controlled the water flows into and out of the two lakes.
  • The barrage would have also served as the Second Severn Crossing.
  • The barrage would have been designed to reduce flooding along the River Severn.
  • There would have been a lock on the English side, to allow ships to pass through the barrage.

The turbines would have been under the airport.

  • They would have generated power by transferring water from the high to the low lake.
  • About ten percent of England’s power could have been generated.
  • I feel, that if the system were to be built now, pumped storage could be incorporated.

The sequence of operation of the power station would have been as follows.

  • On an incoming tide, the sluices in the barrage to the high lake would be opened.
  • Water would flow into the high lake.
  • So long as the water level in the high lake was high enough and the water level in the low lake was low enough, electricity would be generated.
  • On an outgoing tide, the sluices in the barrage to the low lake would be opened.
  • Water would flow out from the low lake.

I believe that because the water levels can be precisely controlled, this tidal power station, would have been able to provide the power needed.

One of their engineers told me, that Harold Wilson’s government had turned the project down, as the Government believed that large coal power stations were the future.

Can you imagine, Canada, Japan, Korea, Norway, Spain, Sweden, Switzerland or many other companies even in the 1970s, taking such a short-sighted decision?

Over the years of this blog, I make no apology about returning to the subject of the Severn Barrage, with these posts.

I still feel strongly, that it was a tragedy for this country, that the Severn Barrage was never built in the last century.

Conclusion

Any engineer, who trained in the 1960s after the Aberfan Disaster knew that coal had no future.

But nobody had seemed to have convinced Harold Wilson of this fact.

So instead of the clean power from the Severn Barrage, we got more polluting coal-fired power stations.

Fifth Hydro Project Proposed At Loch Ness

The title of this post. is the same as that of this article on the BBC.

This is the sub-heading.

The local community is to be asked for its views next week on plans for a new hydro-electric scheme at Loch Ness.

These three paragraphs introduce the new scheme.

Glen Earrach Energy’s, external (GEE) pumped storage hydro project is the fifth hydro scheme proposed for the Loch Ness area.

The company said its project on Balmacaan Estate would create clean energy while protecting the environment, and create 600 on-site jobs.

But concerns have been raised about the number of planned schemes, with Ness District Salmon Fishery Board worried about the effect on wild fish.

The project has a web site, which has a section entitled About The Project, where this is said.

Glen Earrach Energy, which means “Valley of Spring” in Gaelic, stands at the forefront of energy innovation. The Pumped Storage Hydro (PSH) project, located at Balmacaan Estate, Scotland, is a critical component for achieving a net-zero grid by 2030.

The project prioritises environmental preservation and biodiversity enhancement while achieving outstanding efficiency in energy storage and generation.

This ensures a healthier and more sustainable balance between harnessing natural energy resources and the maintenance and reinforcement of the surrounding ecosystem.

Note.

  1. It doesn’t say, but it looks like Glen Earrach Energy aim to complete the project by 2030.
  2. Glen Earrach Energy also seem to be playing a strong environmental card.

But nothing is said about the size of the project.

This article on Business Insider, which is entitled £3 billion Loch Ness Hydro Project Plans Unveiled, does give some details.

  • Potential Investment – More than £2 billion
  • Output – 2 GW
  • Storage Capacity – 30 GWh
  • The project could create at least 600 on-site construction jobs in Scotland over a six-year period, plus many thousands more locally in the supply chain.

It is larger, than SSE’s flagship Coire Glas pumped storage hydroelectric power station, which is planned to be a 1.5 GW/30 GWh station, at the other end of the Great Glen.

I have some thoughts.

The Existing Hydro Schemes On Loch Ness

According to the BBC article, there are two existing hydro schemes on Loch Ness.

  • Foyers is described on this web site and is a reasonably modern 305 MW/6.3 GWh pumped storage hydroelectric power station, that was built by SSE Renewables in the last fifty years.
  • Glendoe is described on this web site and is a modern 106.5 MW conventional hydroelectric power station, that was built by SSE Renewables in the last twenty years.

Foyers and Glendoe may not be the biggest hydroelectric power stations, but they’re up there in size with most solar and onshore wind farms. Perhaps we should look for sites to develop 100 MW hydroelectric power stations?

The Proposed Hydro Schemes On Loch Ness

According to the BBC article, there are four proposed hydro schemes on Loch Ness.

  • Coire Glas is described on this web site and will be a 1.5GW/30 GWh pumped storage hydroelectric power station, that is being developed by SSE Renewables.
  • Fearna is described on this web site and will be a 1.8GW/37 GWh pumped storage hydroelectric power station, that is being developed by Gilkes Energy.
  • Loch Kemp is described on this web site and will be a 600MW/9 GWh pumped storage hydroelectric power station, that is being developed by Statera.
  • Loch Na Cathrach is described on this web site and will be a 450MW/2.8 GWh pumped storage hydroelectric power station, that is being developed by Statktaft.

In addition there is, there is the recently announced Glen Earrach.

  • Glen Earrach is described on this web site and will be a 2GW/30 GWh pumped storage hydroelectric power station, that is being developed by Glen Earrach Energy.

Note.

  1. The total power of the seven pumped storage hydroelectric power stations is 4.76 GW.
  2. The total storage capacity is 85.1 GWh.

The storage capacity is enough to run all turbines flat out for nearly five hours.

Could Glendoe Be Updated To Pumped Storage?

The Wikipedia entry for the Glendoe Hydro Scheme mentions pumped storage several times.

In Glendoe Hydro Power Station, I estimate that a Glendoe pumped storage scheme could be perhaps 50 % bigger than the system at Foyers.

I feel that if more storage capacity is needed in the Highlands, then Glendoe could be converted to pumped storage.
