The Scottish Government has long been supportive of pumped hydro storage capacity, as it believes that pumped hydro storage will play a key role in the energy transition. The Net Zero and Energy Secretary continued:
Scotland's pumped storage facilities are located at Foyers on the shores of Loch Ness and within a giant artificial cavern inside Ben Cruachan on the shores of Loch Awe in Argyll. Despite mild weather, our existing pumped storage - Foyers - has never been used so intensely, according to Mr McCutcheon.
During periods of low energy demand on the electricity network, surplus electricity is used to pump water to the higher reservoir. When electricity demand increases, the stored water is released, generating electricity. Pumped storage hydro (PSH) must have a central role within the future net zero grid.
The same can be applied to solar generation: the pumped storage power station can contribute to constant electricity production at night time when there is no sunshine to run a solar power plant. The flexibility extends not just to the turbine and tank sizes, but also to the depth the system is installed at.
