Up To 24GW Of Long Duration Storage Needed For 2035 Net Zero Electricity System – Aurora

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

This the first three paragraphs.

Deploying large quantities of long duration electricity storage (LDES) could reduce system costs and reliance on gas, but greater policy support is needed to enable this, Aurora Energy Research has found.

In a new report, Aurora detailed how up to 24GW of LDES – defined as that with a duration of four hours or above – could be needed to effectively manage the intermittency of renewable generation in line with goals of operating a net zero electricity system by 2035. This is equivalent to eight times the current installed capacity.

Additionally, introducing large quantities of LDES in the UK could reduce system costs by £1.13 billion a year in 2035, cutting household bills by £26 – a hot topic with energy bills on the rise as a result of high wholesale power prices.

The report also says that long duration storage could cut carbon emissions by ten million tonnes of carbon dioxide per year.

I feel strongly, that this is a target we will achieve, given that there are at least four schemes under development or proposed in Scotland.

It certainly looks like the Scots will be OK, especially as there are other sites that could be developed according to SSE and Strathclyde University.

We probably need more interconnectors as I wrote about in New Electricity ‘Superhighways’ Needed To Cope With Surge In Wind Power.

There are also smaller long duration storage systems under development, that will help the situation in the generally flatter lands of England.

One of them; ReEnergise, even managed to sneak their advert into the article.

Their high density hydro could be a good way to store 100 MWh or so in the hills of England. As they could be designed to fit into and under the landscape, I doubt their schemes would cause the controversy of other schemes.

Conclusion

I think we’ll meet the energy storage target by a wide margin.

ILI Group Announces New 1.5GW Pumped Storage Hydro Project

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

This is the body of the article.

Intelligent Land Investments Group (ILI) has commenced the initial planning phase for its new 1.5 GigaWatt (GW) pumped storage hydro (PSH) project, Balliemeanoch, at Loch Awe in Argyll & Bute.

This is ILI’s third and largest PSH project. Its other PSH projects include ‘Red John’ at Loch Ness, which was awarded planning consent from Scottish Ministers in June Last year, and ‘Corrievarkie’ at Loch Ericht for which they aim to submit a Section 36 planning application in August.

The new project would be able to supply 1.5GW of power for up to 30 hours, enough to power 4.5 million homes.

The project will create a new head pond in the hills above Loch Awe capable of holding 58 million cubic metres of water when full and it is estimated the project will offset more than 200 million tonnes of CO2 emissions over its lifetime.

I would assume that this will be a privately-financed project and at 45 GWh it will be one of the largest pumped storage systems in the world.

But it must show that if it is privately-financed that the big boys in infrastructure finance, see pumped storage as a safe place to put insurance and pension funds to earn a worthwhile return.

  • No-one’s going to steal one of these systems.
  • They are a job-creating asset when built.
  • Hydro-electric power seems very safe, when well-built.
  • You don’t see media reports of schemes like Cruachan, Electric Mountain and Foyers breaking down.

In World’s Largest Wind Farm Attracts Huge Backing From Insurance Giant, I talked about Aviva’s funding for wind farms. If Aviva wukk fund those, surely they’ll fund schemes like this, as it could be argued that they make wind farms a better investment and more valuable, as they won’t have to shut down so often, when there’s too much power.

Red John Pumped Storage Hydro Project

When I wrote ILI Group To Develop 1.5GW Pumped Storage Hydro Project, I noticed that they were also developing a scheme called Red John near Inverness.

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

I have also found a web site for the project, which is part of the ILI Group web site.

  • The scheme has an output of 450 MW.
  • The storage capacity is 2,800 MWh or 2.8 GWh.
  • The scheme has planning consent.
  • The project is budgeted to cost £550 million.
  • The construction program indicates that the scheme will be completed by the end of 2025.

This paragraph from this article on Water Power and Dam Construction, describes the head and tail ponds.

The Red John project will be located on the eastern shore of the north end of Loch Ness in the Highlands of Scotland. Loch Ness is to be the tail pond for the project, with the head pond to be newly constructed. It will use the natural topography between Loch Duntelchaig, Loch Ashie and Loch na Curra and Lochan an Eoin Ruadha, from where the development gets its Red John name.

This Google Map shows the area.

Note.

  1. Loch Ness is in the West.
  2. Loch Ashie is in the North.
  3. Loch Duntelchaig is in the East.

This second Google Map shows the area between Lochs Ness, Duntelchaig and Ashie in more detail.

Loch na Curra and Lochan an Eoin Ruadha are now named and can be picked out in the previous map.

It looks like there will be a lot of heavy construction works to create the head pond.

Conclusion

This scheme has the output of a large gas-fired power station for just over six hours.

The finances must add up, as no-one would back a scheme like this if they didn’t get an adequate return on their money.

ILI Group To Develop 1.5GW Pumped Storage Hydro Project

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

These are the first two paragraphs.

Clean energy developer ILI Group has begun the initial planning phase for a new pumped storage hydro project in Scotland.

The Balliemeanoch project at Loch Awe, Dalmally in Argyll and Bute will be able to supply 1.5GW of power for up to 30 hours. It is the third and largest of ILI’s pumped storage hydro projects, with the other two being Red John at Loch Ness and Corrievarkie at Loch Ericht.

It is a big scheme at 45 GWh.

The ILI Group has an extensive web site, that is worth a read.

  • This page describes pumped storage.
  • This long document from the company is part of their submission to the Government.

The company seems to be going in the right direction.

This Google Map shows the Loch Awe area.

Note.

  1. Loch Awe is in the North West corner of the map.
  2. Loch Fyne is the large loch in the South East corner of the map.
  3. Balliemeanoch is marked by the red arrow.

I am a bit puzzled as to the layout of the scheme.

But I have now noticed a Ballimeanoch close by Loch Awe.

This is a map of its location.

I suspect that is the correct location of the pumped storage scheme.

I shall be interested to see the layout of the full scheme.
