Battersea Power Station is a decommissioned coal-fired power station located on the south bank of the River Thames, in Nine Elms, Battersea, an inner-city district of South West London. It comprises two individual power stations, built in two stages in the form of a single building. Battersea A Power Station was built in the 1930s, with Battersea B Power Station to the east in the 1950s. The two stations were built to an identical design, providing the long-recognized four-chimney layout.
