The North Eastern Electric Supply Company was responsible for the supply of electricity to a large amount of North East England, prior to the nationalisation of the British electricity industry with the Electricity Act 1947. The company was established as the Newcastle upon Tyne Electric Supply Company in 1889, but was renamed the North Eastern Electricity Supply company as it expanded to supply the North East region.

Carville Power Station refers to a pair of now partially demolished coal-fired power stations, situated in North East England on the north bank of the River Tyne at Wallsend. The two stations were built alongside each other on a riverside site about 5 mi (8.0 km) downstream of Newcastle upon Tyne. Carville A Power Station, the first station on the site was opened in 1904, and Carville B Power Station was opened in 1916 to its south.
