Gilkes Reveals 900MW Scottish Pumped Storage Plan

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

This is the sub-heading.

Earba project would be ‘largest in the UK’ in terms of energy stored

And this is the introductory paragraph.

Gilkes Energy has unveiled scoping plans for its 900MW Earba Pumped Storage Hydro Project in Scotland.

These are a few more details.

  • It will have a capacity of 33 GWh.
  • Loch a’ Bhealaich Leamhain is proposed to be the upper reservoir.
  • Lochan na h-Earba is proposed to be the lower reservoir.
  • There will be a three kilometre tunnel between the reservoirs.
  • The 900 MW power station will be on the shore of Loch Earba.
  • Construction is expected to take between 3 and 4 years.

This Google Map shows the location of the site.

And this Google Map shows the site.


  1. Lochan na h-Earba, which will be the lower reservoir is clearly marked, in the North-West corner of the map.
  2. Loch a’ Bhealaich Leamhain, which will be the upper reservoir is in the South-East corner of the map.
  3. Much of Loch a’ Bhealaich Leamhain appears to be frozen, with only a small triangular area of water visible.
  4. There doesn’t seem to be too many roads.
  5. There is a detailed map on the Earba Storage web site.

This looks like it could be extreme construction, at it’s most extreme.


With a power output of 900 MW and a storage capacity of 33 GWh, this pumped storage hydroelectric power station will have the largest storage capacity of any energy storage in the UK.

  1. Just get on and build it as without storage there is no hope of decarbonisation

  2. This is from a statement from SSE in August last year on the News page for Coire Glas, which is another large pumped storage hydro scheme, with 30 GWh of storage.

    SSE Renewables welcomes the Government Response document on large scale and long-duration electricity storage, which further recognises the important role that home-grown long-duration electricity storage technologies can play in not only cost-effectively achieving net zero but in reducing the UK’s reliance on imported gas and contributing to security of supply.

    Exploratory works have started at Coire Glas.

    It seems that the Government and the big companies are on side. The finance should be available, if a money-making contract is signed.

    I wonder, if it’s a shortage of labour, the weather and the midges, that is holding these projects back?

    Or is the money better in the wind industry?
