In 1940 the Electricity Commissioners in agreement with the Central Electricity Board proposed a programme of new generating capacity to mitigate war risks and the growth in demand associated with the development of munitions factories.[2] The programme entailed the installation of 180 MW of plant in four existing stations and two new stations one at Earley east of Reading (51:27.6899N 0:55.5858W) and the other at Castle Meads, Gloucester.[2] Earley was the only power station owned by the CEB; it was operated by Edmundson’s Electricity Corporation until nationalisation in 1948.

The plant was extended in 1944–45 with a second 40 MW set and boilers with a capacity of 400,000 lb/hr (50.4 kg/s).[7] A third 40 MW set with 400,000 lb/hr boilers was installed in 1945–47. In its final configuration there were seven International Combustion boilers each with a capacity of 200,000 lb/hr (25.2 kg/s).[7] Generation was at 33 kV and transmission at 33 kV and 132 kV.

Reading

1940 the Electricity Commissioners in agreement with the Central Electricity Board proposed a programme of new generating capacity to mitigate war risks and the growth in demand associated with the development of munitions factories. The programme entailed the installation of 180 MW of plant in four existing stations and two new stations one at Earley east of Reading and the other at Castle Meads, Gloucester.

Earley was the only power station owned by the CEB; it was operated by Edmundson’s Electricity Corporation until nationalisation in 1948.

1940 Construction started

1942 Supply from Earley began on 8 December 1942 T

Its plant initially comprised a Parsons 40 MW steam turbo-alternator fed from three International Combustion boilers fired with pulverised coal.

1944–45 A second 40 MW set and International Combustion boilers was installed.

1945-7 A third 40 MW set and International Combustion boilers was installed.

1948 Ownership was vested in the British Electricity Authority

Earley was also the site of a pioneering gas turbine, a 56 MW alternator driven by four Rolls Royce Avon jet engines which was commissioned in 1965. A second gas turbine using diesel fuel was installed later.

1970s The steam plant and generators were decommissioned in the 1970s. T

1982 The gas-turbine plant and the whole station were decommissioned.
