Harnessing AI for Grid Efficiency: STEG’s Approach to Modernizing Tunisia’s Energy Sector
The Société Tunisienne de l’Électricité et du Gaz (STEG), established on April 3, 1962, is Tunisia’s foremost public company responsible for the production and distribution of electricity and natural gas. As the second-largest Tunisian company by revenue as of 2009, STEG plays a critical role in the country’s energy infrastructure. With its significant operational scale, integrating Artificial Intelligence (AI) into STEG’s systems offers transformative potential. This article explores the implications of AI within STEG, focusing on operational efficiency, predictive maintenance, and customer engagement.
Historical Overview and Current Operations
A Brief Historical Context
Prior to STEG’s establishment, the Tunisian electricity sector was fragmented among eight different companies. In 1958, the Tunisian government centralized control, and by Decree-Law No. 62-8 in 1962, STEG was founded as a public monopoly. Over the decades, STEG has significantly enhanced Tunisia’s electrification rates, improving urban electrification from 20% to nearly 100% and rural electrification from 6% to 99% over forty years.
Production Capabilities
As of 2011, STEG operates 24 production units with a total capacity of 3,526 MW, predominantly powered by natural gas (82%). The company has historically collaborated with Alstom Power to develop combined cycle power plants in Sousse (1994), Radès (2001), and Ghannouch (2011). These plants exemplify STEG’s commitment to modernizing its infrastructure to meet Tunisia’s growing energy demands.
The Role of AI in Enhancing Operational Efficiency
