The Tongland hydroelectric power station is a hydroelectric power station in the Scottish town of Tongland in the Council Area Dumfries and Galloway . In 1990 the building was included in the Scottish monument lists, initially in category B. The upgrade to the highest monument category A took place in 2002.
history
As early as 1923, the construction and commercial operation of several hydropower plants along the Dee were confirmed as feasible. Since at that time there was no supra-regional electricity network and the demand for electricity in the region was low, further planning was initially suspended. Three years later, the supraregional power grid was completed and a company to build the hydropower plant was founded. Construction of the plant began in 1929 under the engineer William McLellan . When it was completed in 1935, the Tongland hydropower station was the first large-scale facility of its kind in the UK . In 2010 the system was still in operation and it is not foreseeable that it will be discontinued.
description
The power plant is located directly on the right bank of the Dee on the southern edge of Tongland. The A711 runs directly to the west . Three Francis turbines with a diameter of 2.64 m and an output of 11,000 kW each are installed. They have a flow rate of around 120 m³ / s. Furthermore, a 250 watt auxiliary turbine is available as an exciter (see also: exciter systems for synchronous machines ) and an emergency power supply.
The T-shaped building is designed in the Art Deco style. The turbine hall, which is divided into two levels, shows seven vertical design axes on the river side. Colossal pilasters between the elongated windows also structure the façades vertically. The entrance area is on the street side, on the shorter side of the turbine house. The following inscription is embedded above its two-winged entrance portal:
“THE GALLOWAY WATER POWER SCHEME; TONGLAND POWER STATION "
The outer windows on this facade are embedded in round arched recesses. Flanking are twin windows with window posts. Similarly, simple pilasters on the river side structure the facade. A parapet surrounds the final flat roof .
