Price Framework Paves Way For Vast Electricity Storage Scheme
The title of this post, is the same as that of this article on The Times.
This is the sub-heading.
SSE welcomes step forward in plans to build the £1.5bn Coire Glas hydroelectric project
These two paragraphs outline the article.
Ministers have provisionally agreed to a power pricing framework that could pave the way for more pumped storage hydroelectricity projects in Britain, including a gigantic £1.5 billion scheme from SSE that is starting to take shape in the Scottish Highlands.
The Department for Energy Security and Net Zero said it intended to develop a “cap and floor” pricing mechanism that would advance the Coire Glas storage project being developed by SSE, the energy company, and could unlock further pumped storage power stations.
Coire Glas will be one of the largest renewable power projects ever built in the UK.
- It will have a power output of 1.5 GW, which is comparable with some of the large wind farms in the North Sea or four gas-fired power station or Rolls-Royce SMRs.
- It will be able to store 30 GWh of electricity and provide 1.5 GW for twenty hours.
- Coire Glas has a web site.
- Coire Glas will more than double pumped storage hydroelectric capacity in the UK.
Bath County Pumped Storage Station in Virginia, US claims to be the world’s largest battery, but Coire Glas will be able to store more electricity.
You wait decades for one of these monsters to come along in the UK and SSE also have another on the way.
- Loch Sloy hydroelectric power station is the largest conventional hydroelectric power station in the UK.
- It has an output of 152 MW.
- It opened in 1950 and was largely built by German and Italian prisoners-of-war.
SSE plan to convert Loch Sloy power station into a pumped storage hydroelectric power station.
- It will be able to store 25 GWh of electricity.
- Loch Sloy will be the upper lake.
- Loch Lomond will be the lower lake.
- The existing dam, upper lake, pipes and powerhouse will be retained.
- The developments have a web page.
The project is aimed at a commissioning date of 2028.
This paragraph explains how the ‘cap and floor’ mechanism works.
In the scheme, operators would be guaranteed a minimum level of revenue, while consumers would be protected by a price ceiling, above which surplus revenue would be returned to them.
And these two paragraphs give SSE’s reaction.
Finlay McCutcheon, 46, director of onshore Europe at SSE, said the pricing framework was welcome news. He said that a deal for Coire Glas was needed by the end of this year to secure a firm investment decision by early 2026. Planning for the project started in 2007.
“Given the time taken to reach this point, much work is now needed to ensure an effective mechanism is finalised and put in place as early as possible to enable Coire Glas to take final investment decisions and move into construction,” he said.
I believe that the negotiations between the Government and SSE will lead to a monster on Loch Lochy and another one on Loch Lomond.
Conclusion
There are also these pumped storage hydroelectric schemes under development.
- Balliemeanoch Pumped Hydro – 1.5 GW/45 GWh
- Balmacaan Pumped Hydro – 600 MW/15-20 GWh
- Corrievarkie Pumped Hydro – 1.5 GW/14.5 GWh
- Fearna Pumped Hydro – 1.8 GW/37 GWh
- Glenmuckloch Pumped Hydro – 400 MW/1.6 GWh
- Loch Earba Pumped Storage Hydro – 900MW/33 GWh
- Loch Kemp Pumped Storage Hydro – 300MW/9 GWh
- Loch Na Cargeach/Red John Pumped Storage Hydro – 450 MW/2.8 GWh
These total up to 7.4 GW/100+ GWh.
This page on the Strathclyde University web site, gives these GWh figures for the possible amounts of pumped-storage that can be added to existing 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.
Scotland will be the Saudi Arabia of energy storage.
