Battersea Power Station - Design and Specification

Design and Specification

Both of the stations were designed by a team of architects and engineers. The team was headed by Dr. Leonard Pearce, the chief engineer of the London Power Company, but a number of other notable engineers were also involved, including Henry Newmarch Allott, and T. P. O'Sullivan who was later responsible for the Assembly Hall at Filton. Theo J. Halliday was employed as architect, with Halliday & Agate Co. employed as a sub-consultant. Halliday was responsible for the supervision and execution of the appearance of the exterior and interior of the building. Architect Sir Giles Gilbert Scott was involved in the project much later on, consulted to appease public reaction, and referred to in the press as "architect of the exterior". The station was designed in the brick-cathedral style of power station design, which was popular at the time. Battersea is one of a very small number of examples of this style of power station design still in existence in the UK, others being Uskmouth and Bankside. The station's design proved popular straightaway, and was described as a "temple of power", which ranked equal with St Paul's Cathedral as a London landmark. In a 1939 survey by The Architectural Review a panel of celebrities ranked it as their second favourite modern building.

The A Station's control room was given many Art Deco fittings by architect Halliday. Italian marble was used in the turbine hall, and polished parquet floors and wrought-iron staircases were used throughout. Owing to a lack of available money following the Second World War, the interior of the B Station was not given the same treatment, and instead the fittings were made from stainless steel.

Each of the two connected stations consists of a long boiler house with a chimney at each end and an adjacent turbine hall. This makes a single main building which is of steel frame construction with brick cladding, similar to the skyscrapers built in the United States around the same time. The station is the largest brick structure in Europe. The building's gross dimensions measure 160 metres (520 ft) by 170 metres (560 ft), with the roof of the boiler house standing at over 50 metres (160 ft). Each of the four chimneys is made from concrete and stands 103 metres (338 ft) tall with a base diameter of 28 ft tapering to 22 ft at the top. The station also had jetty facilities for unloading coal, a coal sorting and storage area, control rooms and an administration block.

The A Station generated electricity using three turbo alternators; two 69 megawatt (MW) Metropolitan Vickers British Thomson-Houston sets, and one 105 MW Metropolitan Vickers set, totalling 243 MW. At the time of its commissioning, the 105 MW generating set was the largest in Europe. The B Station also had three turbo alternators, all made by Metropolitan-Vickers. This consisted of two units which used 16 MW high pressure units exhausting to a 78 MW and associated with a 6 MW house alternator, giving these units a total rating of 100 MW. The third unit consisted of a 66 MW machine associated with a 6 MW house alternator, giving the unit a rating of 72 MW. Combined, these gave the B station a generating capacity of 260 MW, making the site's generating capacity 503 MW. All of the station's boilers were made by Babcock & Wilcox, fuelled by pulverised coal from pulverisers also built by Babcock & Wilcox. There were nine boilers in the A station and six in the B station. The B station's boilers were the largest ever built in the UK at that time. The B station also had the highest thermal efficiency of any power station in the country for the first twelve years of its operation.
