Grove Road Power Station
1900 St. James's and Pall Mall Electric Light Co and Westminster Electric Supply Co acquired land at North Bank, Marylebone to build a new station.[1]
The Central Electric Supply Co gained permission to build a power station at Grove Road, Marylebone to supply the 2 founding companies, St. James's and Pall Mall Electric Light Co and Westminster Electric Supply Co[2]
1902 November: The station began generating electricity[3]
1902 31 December: high tension current was supplied for the first time from Grove Road Station to Carnaby Street and Mason's Yard stations, supplementing the current generated at those stations.[4]
1911 Current was supplied from Grove Road to the St. James's and Pall Mall Electric Light Co to replace that from one of their 2 small stations.
1912 In view of the good results with the first scheme supplying the St James company, a similar change would also be made at their Carnaby St plant. The Central Electric Supply Co would instal an extra 3000kW generator at Grove Road in order to supply this company[5]
1912 The capacity of the Grove Road plant was being enlarged from 20.2 MW to 40 MW.
1912 A correspondent to The Times identified the company's station as one of 6 which should be considered for bulk supply in an integrated London network; it generated 3 phase 50 Hz 6kV, with DC at 200V-400 V[6].
Acquired by the London Power Co
1930 Description of experimental flue-gas cleaning equipment fitted to No. 26 boiler [7]
1948 Nationalisation of the electricity industry
1964 The generating capacity of Grove Road power station was still 80.25 MW.
1964–65 the boilers were modified for oil firing to take advantage of relatively cheap oil in this period.
1969 The plant was decommissioned.
