Shin Hydro Power Scheme

The Shin hydro-electric scheme was built in the 1930s and 1950s, by the North of Scotland Hydroelectric Board.

  • The scheme is now owned by SSE Renewables and has a page on their web site.
  • There are three individual power stations; Casseley, Lairg and Shin.
  • There are two dams

This map from the SSE Renewables web site shows the layout of the dams and power stations.

The sizes of the power stations in the scheme are as follows.

  • Casseley – 10 MW
  • Lairg – 3.5 MW
  • Shin – 18.6 MW

This gives a total power of 32.1 MW.

This Google Map shows the same area as the SSE Renewables Map.


  1. Shin power station is in the South-West corner of the map.
  2. Loch Shin is the large area of water in the top half of the map.
  3. The village of Lairg is at the South end of Loch Shin.

This Google Map sows Shin power station in detail.


There is a large substation on the left side of the map.

Shin power station is the building straddling the water to the right of the substation.

I have found this informative press release on the SSE web site, which is entitled £5 m Investment In Shin Hydro Station.

These are a couple of paragraphs.

John McDonald, Hydro Manager for SSE said: “This is the first major overhaul of Shin Hydro Station in its 55-year history – a true testament to the reliability and longevity of hydro-electric power.

“There are few other industries that could claim to be making the same product with the same machines and same specifications as they were in the 1950s. This overhaul will mean that Shin will be producing clean, green electricity for decades to come.”

Surely, that is an argument for more hydro schemes.

This Google Map shows Lairg.

Note that there are two dams and a bridge across Loch Shin/River Shin.

This Google Map shows dam at the Southern end of the Loch.

This Google Map shows Lairg dam and power station at the Northern end of the village.

It would appear to be a much simpler scheme, than others I have examined.


I would be very surprised if any pumped storage were to be added to this scheme.

  1. Crikey never knew there was so many hydro stations in this part of Scotland thanks for producing this series of overviews

    • I’m nowhere near finished and when I put what I’m writing all together, you’ll get another surprise.

      I do have a feeling from reading about Shin power station’s upgrade, that elderly hydro power stations attract the type of engineers, who keep a pet steam engine in the shed. But I’d agree with the SSE engineer, that they are a good way to create electricity.
