Lots Road Power Station is a disused coal and later oil-fired and later gas-fired power station on the River Thames at Lots Road in Chelsea, London in the south-west of the Royal Borough of Kensington & Chelsea, which supplied electricity to the London Underground system. It is sometimes erroneously referred to as Fulham Power Station, a name properly applied to another former station a mile south-west along the Tideway. History A power station at Lots Road was originally planned by the Brompton & Piccadilly Circus Railway (B&PCR, now part of the Piccadilly line) in 1897. The B&PCR was controlled by the District Railway (DR, now the District line) from 1898, and was sold in 1901 to Charles Yerkes' Metropolitan District Electric Traction Company, which built the station to provide power to the DR. The station allowed the District line trains to change from steam haulage to electric. At around the same time the Metropolitan Railway built its power station at Neasden. The station was built end-on to the Thames, on the north bank of the tidal Chelsea Creek. Construction started in 1902 and was completed in December 1904, the station becoming operational on 1 February 1905. The station burned 700 tonnes of coal a day and had a generating capacity of 50,000 kW. At the time it was claimed to be the largest power station ever built, and it eventually powered most of the railways and tramways in the Underground Group. The station was re-equipped and improved several times. During the early 1920s a sump and hopper system for more efficient fuel handling was installed. It was designed by The Underfeed Stoker Company and constructed under their stewardship by Peter Lind & Company, who still trade in London today. The modernisation undertaken in the 1960s converted the station from Hz to 50 Hz generation and from coal burning to heavy fuel oil. The number of chimneys was reduced from the original four to two. Between 1974 and 1977, with the discovery of natural gas in the North Sea, the boilers were converted to burn gas, with the option of oil firing if required. The station later worked in conjunction with the ex-London County Council Tramways power station at Greenwich to supply the London Underground network. The station played a part in the birth of commercial radio in the UK. When the first two radio stations, LBC and Capital Radio, opened
