Tunisia and Japan Develop Smart Electricity Demand Forecasting System

Tunisia's electricity sector is undergoing a significant transformation with the development of an "Automated Electricity Demand Forecasting System." This innovative tool was jointly created by experts from the Société Tunisienne de l’Electricité et du Gaz (STEG) and the Japan International Cooperation Agency (JICA) as part of the "Decarbonization and Stable Supply of the Tunisian Electricity System" project.

The system employs advanced machine learning algorithms to modernize daily demand forecasting. It aims to provide more accurate predictions that account for real-time weather conditions, thereby enhancing the efficiency and reliability of the national electricity grid. This development is crucial as Tunisia aims to source 35% of its electricity from renewable energy by 2030, a goal that introduces variability into the grid's stability.

Beyond demand forecasting, the two-year project, launched in 2024, also focused on integrating electric vehicle (EV) charging infrastructure into the national grid. This involved technology transfer and knowledge sharing to ensure seamless and safe integration. The findings will directly inform STEG's technical requirements for connecting charging infrastructure to the national grid.

Furthermore, the project addressed the implementation of Battery Energy Storage Systems (BESS). STEG has developed draft technical specifications for grid-connected BESS, which are expected to be finalized soon. These advancements collectively aim to bolster the stability and adaptability of Tunisia's electricity system in the face of growing renewable energy penetration and evolving energy demands.

JICA is very proud to have accompanied STEG in its efforts to adapt its electricity grid management system and its infrastructure to the new context of renewable energies in Tunisia.
