A giant tunnel over a kilometre long has been completed as part of work towards building a major new hydro energy storage facility.
The tunnel towards the proposed underground powerhouse is a key stage in the £100 million pumped storage hydropower plant that would almost double the UK's existing electricity storage capacity.
The proposed Coire Glas project at Loch Lochy in the Great Glen would have an installed capacity of 1,300 megawatts (MW) and be capable of delivering 30 gigawatt hours (GWh) of long-duration electricity storage.
It would provide renewable power for three million homes for up to 24 hours, and be the largest UK hydropower energy site in the UK for 40 years.
Pumped storage hydropower projects work by using the flow of water between reservoirs and lochs to drive turbines.
SSE Renewables said the tunnel will allow the project team to gather accurate information on the geological conditions to inform the detailed design for the main works.
