Tralaig Dam provides water storage and flow regulation for Kilmelford Power Station.

Water from the dam passes through a small compensation set before entering the stream bed below the downstream face of the dam and flowing into Oude Dam which provides additional storage and flow regualtion for the power station.

The dam is of mass gravity type, it is relatively small in scale with two large earth embankment wings flanking a small central spillway and control tower incorporating comp set.

  • Part of the Sloy Awe scheme
  • Located near Oban, Argyll and Bute
  • 0.1MW capacity

Power from the Glens

Scottish Hydro Electric, then known as the North of Scotland Hydro Electric Board and now part of SSE, was established by an Act of Parliament in 1943.

It was to be responsible for generating, transmitting, distributing and supplying electricity throughout the north of Scotland, including the Highlands and Islands. This covers about 25% of the total land area of Britain but just 3% of the population. The region contains Britain’s highest mountains and largest inland lochs which, combined with high rainfall, make hydro electricity viable.

Hydro electricity is produced using the power of running water to turn the turbines of generating sets in power stations. The technology dates back to the late 19th Century when the first privately owned hydro electric power stations were built to power the aluminium smelting industry and to provide local electricity supplies. But it took the vision of one man, Tom Johnston, the Secretary of State for Scotland in Churchill's wartime coalition government, to bring power from the glens for the benefit of all. At the time, it was estimated that just one farm in six, and one croft in a hundred, had electricity. Today, virtually every home in Scotland has mains electricity.

Today, hydro electricity, together with wind farms and emerging technologies such as wave and tidal power, is helping the country meet its commitment to provide increasing amounts of energy from renewable sources. A major refurbishment programme of Scottish Hydro Electric’s hydro stations has ensured these wonderful assets can produce clean electricity for the nation for decades to come.

This booklet is dedicated to the memory of the ‘Hydro Boys’ whose legacy is the largest source of renewable energy in the country.
