Revamp of SSE's Foyers power station on Loch Ness
A hydro power station at Foyers on the shores of Loch Ness is undergoing an £8m refurbishment.
Electricity has been generated in the area since 1896 when power was needed to supply an aluminium smelter, which was shut down in 1971.
From 1974, Foyers has had a combined pumped storage and conventional hydro electric scheme.
Energy giant SSE said the revamp will extend the life of the site by several decades.
New components and a large crane are to be delivered to the site next month.
