Société Tunisienne de l'Électricité et du Gaz

Operating nationwide, STEG manages a diverse portfolio of power plants that include conventional thermal units as well as emerging renewable energy installations such as solar and wind farms. The company maintains an extensive high-voltage transmission network and distribution grids that deliver energy to residential, commercial, and industrial users across urban and rural areas.

As a government-owned entity, STEG plays a central role in implementing Tunisia's national energy strategy, including efforts to increase the share of renewables in the energy mix and improve energy efficiency. It frequently serves as the offtaker in power purchase agreements with independent power producers, securing long-term supply contracts for new projects.

Headquartered in the capital city of Tunis, the company has a significant workforce and invests in infrastructure upgrades and technological advancements to meet increasing demand. While it holds a dominant market position, the Tunisian energy sector is seeing gradual liberalization with private sector involvement in generation. STEG collaborates with international partners and financial institutions on major projects to expand capacity and modernize the grid.
