Prior to the construction of Barking A Power Station, Barking Town Urban District Council operated its own small power station near its offices from 1897 until its closure in 1927.

[1] In 1920, the County of London Electric Supply Company applied for permission to build a power station at Creekmouth in Barking capable of expansion to 600 MW.

Steam pressure and temperature at the turbine stop valves was 350 psi (24 bar) and 371 °C.

[4] Barking Power Station was opened by King George V on 19 May 1925 and was brought into commercial operation on 1 January 1926.

[5] In 1927 it took over from the Barking Town Urban District Council station, providing a bulk electricity supply.

[1] A cable tunnel was constructed under the river to supply the south bank with electricity.

The B Station had 16 B&W chain grate boilers, each capable of producing 256,000 lbs steam per hour (32.3 kg/s).

[7] The British Electricity Authority built a third station at Creekmouth, which was completed in 1954.

[13] In July 2014 the operators announced their intention to close the power station within two years.

[14] Decommissioning of the power station started in 2018, the chimneys being demolished using explosives.
