Single phase, 75 Hz AC at 100 and 200 volts 3-phase, 50 Hz AC, at 200 and 400 volts 500 volt DC for traction current. This was supplied to the Burton upon Trent Corporation tramways which operated from 1903 to 1929. New plant New low pressure (LP) plant was commissioned in 1924–28 and high pressure (HP) plant in 1941–43. Boilers: 8 × Babcock & Wilcox CTM boilers with chain grate stokers, 2 × Babcock & Wilcox land type boilers with chain grate stokers The working pressures were: LP 200 psi and 620, 640 & 650°F (13.8 bar and 327, 338, 343°C) HP 375 psi and 800°F (25.86 bar and 427°C) The boilers had a total evaporative capacity of 536,000 lb/h (67.5 kg/s), and supplied steam to: Turbo-alternators: 1 × Parsons 6 MW turbo-alternator, 1 × 7.5 MW British Thomson-Houston turbo-alternator, 2 × Brush 15 MW, turbo-alternators. The completed total installed generating capacity was 43.5 MW, with an output capacity 41 MW. Condenser cooling water was taken from the River Trent. The electrical switch gear was remote controlled Metro-Vickers. Operations The operating data for the period 1921–23 is shown in the table: The growth of demand and use of electricity is evident. Under the terms of the Electricity (Supply) Act 1926 (16-17 Geo. 5 c. 51) the Central Electricity Board (CEB) was established in 1926. The CEB identified high efficiency ‘selected’ power stations that would supply electricity most effectively; Burton upon Trent was designated a selected station. The CEB also constructed the national grid (1927–33) to connect power stations within a region. Operating data 1946 Burton upon Trent power station operating data for 1946 is given below. The British electricity supply industry was nationalised in 1948 under the provisions of the Electricity Act 1947 (10-11 Geo. 6 c. 54). The Burton upon Trent electricity undertaking was abolished, ownership of Burton upon Trent power station was vested in the British Electricity Authority, and subsequently the Central Electricity Authority and the Central Electricity Generating Board (CEGB). At the same time the electricity distribution and sales responsibilities of the Burton upon Trent electricity undertaking were transferred to the East Midlands Electricity Board (EMEB). Operating data 1954–72 Operating data for the period 1954–72 is shown in the table: The less intensive use of the plant is evident. The output of the station in GWh was: In 1958 the Burton electricity district supplied an area of
