Tunisia has launched a tender for the development of a 300MW solar power plant paired with a large battery storage system, as part of the country’s efforts to accelerate the transition to renewable energy and strengthen electricity supply.
The project will be located in Bazma in the southern Kebili governorate, an area with strong solar irradiation. According to Tunisia’s Ministry of Industry, Mines and Energy, the facility will combine a 300 MW photovoltaic plant with a 150 MW/540 MWh battery energy storage system (BESS).
The hybrid installation will occupy about 440 hectares of land and is expected to become the country’s first solar plant integrated with large-scale battery storage.The project will be implemented under a concession agreement within Tunisia’s national renewable energy development programme, which aims to expand renewable generation and improve grid reliability through energy storage technologies.

Terms of registration
Developers interested in the project must register through the government’s AO 01-2026 tender portal by May 8, 2026, after which tender documents will be shared with eligible bidders. The deadline for bid submissions is October 14, 2026, at noon Tunis time. The initiative forms part of Tunisia’s wider plan to significantly increase the share of renewable power in its energy mix. Authorities are targeting 35% renewable electricity by 2030 and 50% by 2035, requiring the addition of more than 5 GW of new renewable energy capacity in the coming years.
Tunisia has already begun expanding its solar portfolio. In early 2025, the government awarded contracts for four solar power projects with a combined capacity of 500 MW to international developers including Germany’s Qair Group, Norway’s Scatec, France’s Voltalia, and Japan’s Aeolus. These projects formed part of the first phase of a broader programme of solar and wind developments expected to deliver around 1,700 MW of generation capacity. Further expansion is also planned. In December, authorities approved over 2.3 GW of renewable energy projects for tender in 2026, including 2 GW of wind capacity and an additional 350 MW solar project.
Investment in renewable energy is also increasing. Official data show that foreign direct investment (FDI) into Tunisia rose by nearly 39% in 2025 to about US $2.8bn (TD8.3 billion), up from TD6 billion in 2024, with renewable energy projects attracting approximately TD1.6 billion. By combining solar generation with battery storage, the Bazma-Kebili project is expected to play an important role in improving grid stability, reducing reliance on fossil fuels, and strengthening Tunisia’s long-term energy security.
