Building Inside Mountains: Global Demand For Pumped Hydroelectric Storage Soars
The title of this post, is the same as that of this article on Construction-Europe.
This is the sub-heading.
Pumped hydroelectric storage plants around the world have been secretly storing electricity in remote mountain lakes for the last century. But the switch to renewable energy sources is prompting a surge in new construction.
These two paragraphs introduce the article.
Looking out over the ragged beauty of the Scottish Highlands, Coire Glas, a horseshoe-shaped valley holding a clear mountain lake above the shores of Loch Lochy, seems like an unlikely spot to build a megaproject.
In this remote location, surrounded by clumps of pine trees, a team of construction workers from contractor Strabag are tunnelling their way through the rock which they hope will form part of a vast new power storage facility.
The article is a must-read that talks about pumped storage hydroelectricity in general and SSE Renewables’s 1500MW/30 GWh Coire Glas power station in particular.
The Future Of Pumped Hydroelectric Storage
These two paragraphs from the article give a glimpse into the future.
According to the International Energy Agency, global pumped storage capacity is set to expand by 56% to reach more than 270 GW by 2026, with the biggest growth in India and China.
Current pumped storage megaprojects currently in construction include the Kannagawa Hydropower Plant near Minamiaki in Japan which when fully completed in 2032 is expected to have a total installed capacity of 2,820MW; and Snowy Hydro 2.0 in New South Wales, Australia, which is currently expected to complete in 2028.
Note.
- I can count two Indian and ninety Chinese systems under construction. All have a capacity of upwards of one GW.
- The Kannagawa Hydropower Plant appears to be the largest with a capacity of 2.82 GW. The Japanese are keeping quiet about the storage capacity.
- The Snowy Hydro 2.0 has a capacity of 2 GW and a storage capacity of 350 GWh.
- The Wikipedia entry for Snowy Hydro 2.0 states that it is the largest renewable energy project under construction in Australia.
Against this onslaught of massive systems, SSE Renewables are pitching the 1500MW/30 GWh Coire Glas and the 252MW/25 GWh Loch Sloy systems.
Pumped hydroelectric storage will have a big part to play in decarbonising the world. Even in little old and relatively flat UK.
The Anonymous Widower 
Coire Glas is mission critical for UK and govt should have told SSE to get on with it and give them financial guarantees like we have done for Hinkley Point B.

Yes they, the Government have managed Cap and Floor revenue stabilisation for the Interconnections so we can only imagine that their decision making capabilities have atrophised. Seems a widespread feature of the Tories…….. I wonder if the rest of them will be any better.
