Luton power station supplied electricity to the Borough of Luton and the surrounding area from 1901 to 1969. The power station was operated by the Luton Corporation until the nationalisation of the British electricity industry in 1948. It was redeveloped after the First World War to meet the increased demand for electricity.
Luton Corporation obtained a Provisional Order in 1895 under the Electric Lighting Acts to generate and supply electricity to Borough of Luton. The Order was granted by the Board of Trade and was confirmed by Parliament through the Electric Lighting Orders Confirmation (No. 2) Act 1895 (58 & 59 Vict. c. lxvii).[1] The corporation built a power station in St Mary's Road, Luton (51°52’45”N, 00°24’34”W)[2] which was commissioned in 1901.
Luton power station supplied electricity to Luton Corporation Tramways from the opening of the system in 1908 until its closure in 1932.[3]
The British electricity supply industry was nationalised in 1948 under the provisions of the Electricity Act 1947 (10 & 11 Geo. 6 c. 54).[4] The Luton electricity undertaking was abolished, ownership of Luton power station was vested in the British Electricity Authority, and subsequently the Central Electricity Authority and the Central Electricity Generating Board (CEGB).[5] At the same time the electricity distribution and sales responsibilities of the Luton electricity undertaking were transferred to the Eastern Electricity Board (EEB).
Luton power station was closed in 1969.[6] The power station was demolished in 1972.
By 1923 the plant comprised boilers delivering 166,000 lb/h (20.9 kg/s) of steam to:[7]
These machines had a total generating capacity of 7,400 kW; comprising 2,400 kW DC and 5,000 kW AC.
Electricity supply to consumers was at 250 and 500 V DC.
By 1954 the plant comprised:[8]
The total generating capacity was 23 MW and the output capacity was 13 MW.
Condenser water was cooled in two Mouchel reinforced concrete cooling towers each with a capacity of 1.0 million gallons per hour (4,546 m3/hour).
The boilers were converted to oil firing in 1965.[9]
