Largest ever UK pumped hydro scheme granted consent

Planning permission granted for 1.8 GW/ 40 GWh pumped hydro project in the Scottish Highlands. Developer Gilkes Energy says the real work begins now and is seeking “substantial capital” for the project.

 

Gilkes Energy has secured planning consent for a 1.8 GW/40 GWh pumped hydro energy storage project, the largest of its kind to date in the United Kingdom.

 

The Earba Pumped Storage Hydro project is located at Loch Earba in the Scottish Highlands, around 200 km north of Glasgow on the edge of the Cairngorms National Park.

 

The proposed development would operate by transferring water between Loch Earba and an upper reservoir, Loch Leamhain. When the project’s upper reservoir is full, it would have enough storage capacity to generate 22 hours of electricity at its full 1.8 GW power rating, according to planning documents for the project.

Now doubt then that it will end up being owned by some foreign state fund or pension fund, because UK equivalents will be too short sighted  to consider investing

Pretty much, which is why Great Britain is now just Britain.....
