Newcastle and District Electric Lighting Company

The Newcastle and District Electric Lighting Company (abbreviated to DISCo) was a pre-nationalisation, private electricity supply company, based in Newcastle upon Tyne in North East England. The company was set up in 1889 by Charles Algernon Parsons. The company built a number of small coal-fired power stations in the west end of Newcastle upon Tyne, initially to supply homes and streets with electric lighting. They also provided power for an electrified tram line in the western part of the city.

DISCo was the first electric supply company in the world to generate electricity using turbo generators, thanks to Parsons' invention of the steam turbine. The company existed until the nationalisation of the UK's electrical supply industry in 1948.

Following his invention of the steam turbine in 1884, Charles Algernon Parsons was anxious to move into electricity supply, and so in 1889 he founded up the Newcastle and District Electric Electric Lighting Company. Their distribution area was quickly decided; they were to supply the area of the city to the west of Grainger Street, while the Newcastle-upon-Tyne Electric Supply Company (NESCo), who had also been formed in 1889, were to supply the eastern side of the city. DISCo's distribution area was expanded west to Newburn in 1902, and north to Benwell and Fenham in 1904. They were unable to extend this any further after losing a number of Parliamentary battles with NESCo in the early 1900s.
