The United Kingdom Central Electricity Board (CEB) was established by the Electricity (Supply) Act 1926. It had the duty to supply electricity to authorised electricity undertakers, to determine which power stations would be 'selected' stations to generate electricity for the board, to provide main transmission lines to interconnect selected stations and electricity undertakers, and to standardise generating frequency.
In 1925 Lord Weir chaired a committee that proposed the creation of the Central Electricity Board to link the UK’s most efficient power stations with consumers via a ‘national gridiron’. At that time, the industry consisted of more than 600 electricity supply companies and local authority undertakings, and different areas operated at different voltages and frequencies (including DC in some places). The board's first chairman was Andrew Duncan.
The CEB established the UK's first synchronised AC grid, running at 132 kilovolts and 50 Hertz, which by 1933 was a collection of local grids, with emergency interlinks, covering most of England. This started operating as a national system, the National Grid, in 1938.
After completion of the National Grid the role of the CEB changed from planning and construction to operating and managing the regional grid systems. [1]
The CEB established laboratories at Croydon and Waddon to undertake research on high voltage transmission problems. [2]
The CEB co-existed with the Electricity Commissioners, an industry regulator responsible to the Ministry of Transport.
The CEB ceased to exist when the electricity industry was nationalised by the Electricity Act 1947 and taken over by the British Electricity Authority.
There were four chairmen of the Central Electricity Board between 1927 and 1948:
Upon its establishment in 1927 the Board comprised a full-time chairman and seven part-time members, all appointed by the Minister of Transport. [5] The inaugural part-time members were:
Under the board were a general manager, secretary, chief engineer, commercial manager and support sections. [5] Some key people were:
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°27.6899′N0°55.5858′W / 51.4614983°N 0.9264300°W ) and the other at Castle Meads, Gloucester. [2] Earley was the only power station owned by the CEB; it was operated by Edmundsons Electricity Corporation until nationalisation in 1948.
The supply from Earley commenced on 8 December 1942, only 22 months after the start of construction. [2] The plant initially comprised a Parsons 40 MW steam turbo-alternator fed from three boilers with a total steam capacity of 600,000 lb/hr at 635 psi at 850 °F (75.6 kg/s, 43.8 bar at 454 °C). [7] The boilers were fed with pulverised coal. 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. Cooling water was abstracted from the river. [7]
Upon nationalisation of the British electricity supply industry in 1948 the ownership of Earley power station was vested in the British Electricity Authority, and subsequently the Central Electricity Authority and the Central Electricity Generating Board (CEGB). [2]
Earley was also the site of a pioneering main-service gas turbine, this was a 56 MW machine driven by four Rolls-Royce Avon jet engines and was commissioned in 1965. A second diesel-fired gas turbine was installed later. [2]
The operating parameters and electricity output of Earley power station is given in the following table. [7] [8] [9] [10]
