International Energy Transition Exhibition: Tunisia Aims for 35% Renewable Energy by 2030
During the International Energy Transition Exhibition, held on November 26-28 at the UTICA, the Tunisian Electricity and Gas Company (STEG) reaffirmed the national ambition to increase the share of renewable energy to 35% of the energy mix by 2030. This target relies on an accelerated growth of solar and wind power, as detailed by Mounir Hajjej, STEG representative, during his presentation on the progress of major projects.
National Energy Strategy
Hajjej recalled that the national energy strategy is based on three pillars: energy control, development of renewable energies, and reduction of greenhouse gas emissions. "Tunisia aims to install a power mix composed of 25% wind and 75% solar photovoltaic," he stated, highlighting the consistency of this vision with the country's climate commitments.
STEG's Priorities
As the national operator, STEG structures its action around three priority axes: energy efficiency, renewable development, and carbon footprint reduction.
Major Projects in Development
Several structuring projects are under development, including:
- 300 MW of photovoltaic power, including a project in the Tataouine governorate, with a first phase of 50 MW and 20 MW of BESS storage. A call for tenders is planned for December 2025.
- 100 MW of additional wind power.
- 500 MW of IPP projects in the development phase.
- 1.7 GW of IPP projects, with calls for tenders launched in December 2022.
ProSol Elec Program
The ProSol Elec program, launched in 2010, continues to progress, with 384 MW installed as of September 2025. STEG provides technical, financial, and logistical support to customers with an annual consumption of 1,200 to 1,800 kWh.
Network Modernization
The massive integration of renewable energies requires a profound transformation of the national electricity grid. In the short term, STEG aims to strengthen the flexibility of local production. In the medium term, the goal is to better anticipate the fluctuations in production of intermittent energies.
Three levers structure this modernization:
- A national monitoring system for real-time supervision.
- The development of flexibility solutions, including gas turbines, pumping-turbine stations, and BESS storage.
- The Tunisia-Italy interconnection project "ELMED", considered a key infrastructure for the future.
Smart Grid and Interconnections
Hajjej also highlighted the progress of the Smart Grid project, aimed at balancing supply and demand, integrating decentralized production, and optimizing network performance. To date, 4,000 smart meters have been installed on the medium-voltage network, and 30,000 on the low-voltage network.
