 In the early 1900s, an increasing number of areas were being provided with electricity, and train and tram lines were being electrified.In the area around Newcastle upon Tyne, this required the opening of power stations at Wallsend, Forth Banks and The Close.Two supply companies built the stations, the Newcastle-upon-Tyne Electric Supply Company (NESCo) to the east of Newcastle, and the Newcastle and District Electric Lighting Company (DisCo) to the west.
