An electricity generating station was opened in Bridge Street in 1902. Initially it was capable of generating 75 kW of power, but by the time of its closure in 1941, its installed capacity was 2.2 MW. Under the Electricity (Supply) Act 1926, Leatherhead was connected to the National Grid, initially to a 33 kV supply ring, which linked the town to Croydon, Epsom, Dorking and Reigate. In 1939, the ring was connected to the Wimbledon-Woking main via a 132 kV substation at Leatherhead.
