The story

Until August 1959 the Tunisian electricity industry was divided among eight different companies. Having decided to temporarily take over these companies, the Tunisian government site, 15 August 1958, a management committee at the head of one of these companies known as Tunisian Company of Electricity and transport. By Decree-Law No. 62-8 of 3 April 1962, the State terminates this situation by creating a public monopoly given to the STEG.

Shortly after, an electrification policy is in place that, in forty years, the urban electrification rate of 20% passed nearly 100% and the rural electrification rate from 6% to 99%.
