Culligran Tunnel [Culligran Power Station]

Culligran, Glen Strathfarrar, Inverness-shire.

Access tunnel / Subsurface hydro electric scheme (1962-).

"Water is taken from an intake structure adjacent to Beannachran dam into the main Culligran tunnel, 17,000ft long, to the surge chamber, which is of the differential type, with seperate main and riser shafts. From there the water falls down a vertical high-pressure shaft, from the base of the shaft a short length of high-pressure tunnel leads to Culligran power station, which is constructed underground. After passing through the turbines at Culligran, a short tailrace tunnel discharges the water into the river Farrar." [Corestore]

"the River Farrar is dammed just below Loch Beannacharan, with a tunnel to take water to Culligran power station, which is also built underground." [Wikipedia]
