In takes advantage of water flowing from the Mullardoch Dam to the tunnel, and has an installed capacity of 2.4 megawatts and an average annual output of eight million units of power. This view shows the top of the shaft being sunk for the waste water from the small Mullardoch generating station. The cylinder on the left is a four-foot diameter, nine-foot long drilling bit, to make a shaft four feet in diameter. In the centre is a device for removing the stone cylinder (core) cut out of the rock. The Mullardoch-Fasnakyle-Affric Project was the first part of the Affric/Beauly scheme to be built by the North of Scotland Hydro-Electric Board.
