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.
