Affric-Cannich section. The principal works are a 48m dam at Loch Mullardoch on the River Cannich, a 5km tunnel to Loch Benevean on the
River Affric, a smaller dam at Loch Benevean and another tunnel to the
main generating station at Fasnakyle in Strathglass. The area is very
remote and road construction and subsequent hydroelectric plant
operation were designed to preserve scenic and natural resources. The
generators are directly connected by underground cables to the main
transformers and switchgear, concealed in a former gravel pit nearby.
