Kendoon Power Station

This power station receives water from Kendoon Loch (NX69SW 89) through the aqueduct NX68NW 108.00 and the pipeline NX68NW 108. It forms a major component of Stage II of the Galloway Hydro-Electric Scheme.

This project was undertaken to input site information listed in 'Civil engineering heritage: Scotland - Lowlands and Borders' by R Paxton and J Shipway, 2007.

This station is about one mile downstream from Ken Dam, and just south of the junction of the Blackwater Burn tributary. It contains two 10.5MW turbines of the vertical-shaft single-floor type. The natural gradient of the two mile stretch of river below the power station has been utilised by the construction of Carsfad Dam, which ponds the water back to one foot below the level of the concrete sill controlling the tail-race level at Kendoon.

Carsfad power station operates in conjunction with Kendoon where greater storage is available. The entrance

to the power station intake at Kendoon is protected by a series of vertical screens to safeguard fish from being

trapped as they enter the fish pass. A similar arrangement exists at Carsfad. The consulting engineer was Sir Alexander Gibb & Partners and the main contractor, A. M. Carmichael Ltd.

This powerhouse receives water from Kendoon Loch and has two installed turbines used to generate electricity. The installed plant, and design of the building is very similar to that seen at Glenlee (which predates it), Carsfad and Earlstoun. This station is of almost identical design to Earlstoun, Carsfad and Glenlee. The powerhouse exhibits a functionalist modern classical design which characterises the Galloway scheme, illustrating the dynamic modern view which was held of the industry at this time. The powerhouse retains major interior features such as the overhead crane by William Arrol. It is prominently sited, and the striking design makes a good landscape contribution. The grouping of the building with the adjacent valve-house is also of additional interest. P L Payne, 1988, 24; E Wood, 2002, 50; G Hill, 1984.
