Description

Sir Alexander Gibb consulting engineers; Merz and McLellan, electrical engineers, 1936. Tall cylindrical steel surge tower. Riveted plate steel with advanced eaves course. Integrated with 2 large pipes to base.

Statement of Interest

The Kendoon surge tower is an iconic feature in the landscape and relatively unusual amongst a building type which is predominantly subterranean or semi-subterranean. The surge tower protects the integrated penstocks from sudden surges of water, which, instead of bursting the pipes or damaging turbines is accommodated by the hollow interior of the tower. In extreme floods the water could overtop the tower.

The surge tower makes a significant contribution to the landscape from a prominent site on an area of sloping ground surrounded by a wide bowl of hills. The striking cylindrical feature is a bold statement set against a natural backdrop of mature woodland. The bold form is characteristic of the dynamic modern view which was taken of hydroelectricity during this period.

The development of the Galloway Hydroelectric Scheme predates the 1943 Hydroelectric (Scotland) Act which formalised the development of Hydroelectricity in Scotland and led to the founding of the North of Scotland Hydroelectric Board. Those developments which predated the 1943 act were developed by individual companies as a response to particular market and topographic conditions. The completion of a number of schemes (including Galloway, Grampian and those associated with Alcan ' see separate listings) without a national strategic policy framework is groundbreaking as is the consistency of high quality aesthetic and engineering design across all of the schemes.

The Galloway scheme was influential on the future development of hydropower in Scotland. After initial opposition to the parliamentary act granting powers for the completion of the scheme it was approved with a number of safeguards on the landscape and amenity of the area. This necessitated the high quality design of both power stations and dams which characterises the Galloway scheme. This condition also proved influential during the drafting of the Hydroelectric (Scotland) Act of 1943 where the visual impact of future schemes was a primary concern.

Sir Alexander Gibb and Partners was a pioneering engineering company, responsible for a number of high profile works in Scotland, including the Kincardine Bridge (see separate listing). The company was founded by Alexander Gibb in 1921 and quickly became the UK's largest firm of consulting engineers with numerous international clients. Gibb was personally involved in the design and construction of the Galloway scheme, and the pioneering nature of the Galloway development is due, in large part, to his abilities as an engineer. Merz and McLellan were pioneering British electrical engineers and developed a high profile practice, working on a number of power stations across Britain, including Dunstan B, as well as completing hydroelectric work in Italy in the 1980s.
