Earba 1.8GW Pumped Storage Hydro Project Secures Approval
The title of this post, is the same as that of this article on the Solar Power Portal.
These three paragraphs introduce the article.
Gilkes Energy has been awarded planning consent for its Earba Pumped Storage Hydro (PSH) scheme.
The Earba PSH scheme is set to be the largest project of its kind in the UK, with an installed capacity of 1.8GW and a storage capacity of 40GWh, meaning that it can provide 22 hours of storage at full power. The planning application for the project was submitted to the Scottish government in early March 2024.
The project will be located at Loch Earba in the Scottish central Highlands. Gilkes Energy states that this location was chosen because the area has an ideal combination of geology and topography, which the firm states will make it one of the most economically viable PSH projects under development in the UK.
In Gilkes Reveals 900MW Scottish Pumped Storage Plan, I said that Loch Earba was a 900 MW/33 MWh PSH scheme, but now it appears a it is 1.8 GW/40 GWh scheme, which will probably put it in the largest twenty PSH schemes in the world.
It will be one of four PSH schemes under development in Scotland.
- Coire Glas – 1.3 GW/30 GWh
- Loch Earba – 1.8 GW/40 GWh
- Loch na Cathrach (formerly known as Red John) – 450 MW/2.8 GWh
- Loch Sloy – 160 MW/16 GWh
In addition.
- Cruachan is being extended to 1 GW/7 GWh.
- Highview Power are planning to build two 200 MW/2.5 GWh of their liquid air batteries in Scotland.
Everything totals up to 5.1 GW/100.8 GWh, which compares with a UK electricity production as I write this article of just under 29.5 GW.
I wouldn’t be surprised to see some high-energy industries moving to Scotland because of all this renewable and hopefully reliable power.
