The UK’s Pumped Storage Hydroelectricity

This post is a simple list of the UK’s pumped storage hydroelectricity.

  • Balliemeanoch – 1500 MW/45 GWh – In Development
  • Coire Glas – 1500 MW/30 GWh – Under Construction
  • Corrievarkie – 600 MW/14.5 GWh – In Development
  • Cruachan – 1000 MW/7.1 GWh – In Operation
  • Fearn – 1800 MW/37 GWh – In Development
  • Dinorwig – 1800 MW/9.1 GWh – In Operation
  • Earba – 900 MW/33 GWh – In Development
  • Foyers – 305 MW/10 GWh – In Operation
  • Ffestiniog – 360 MW/1.44 GWh – In Operation
  • Loch Kemp – 600 MW/9 GWh – In Development
  • Loch Sloy – 152.5 MW/25 GWh – In Operation
  • Red John – 450 MW/2.8 GWh – Under Construction

Note.

  1. Cruachan is only 440 MW and is being upgraded.
  2. The storage capacity at Foyers may be wrong, as I can’t find my original source.

When fully developed the total will be 10969.3 MW/223.94 GWh.

  1. Here’s one that I think was overlooked. Fearna is near Inverness

  2. I see on the Drax website that they have awarded an £80 million contract to Austria’s Andritz Hydro for the 10% expansion of the Cruachan pumped storage facility.

    • Now that National Grid is planning 8 GW of electricity mega highway between Scotland and England, there will be a need to feed power continuously from Scotland to the South of England and Europe and pumped storage is the way to do it.

      I still expect RWE to build one of the world’s largest electrolysers off or in North-East Norfolk to create hydrogen for Europe.

      Whoever wins the next election, should have it made!
