The Bazma solar project in Tunisia's Kébili governorate is entering its final phase. The project involves a 300 MW photovoltaic power plant accompanied by a 150 MW/540 MWh battery energy storage system. The Ministry of Industry, Mines, and Energy launched a call for tenders for the project, with interested investors having until October 14, 2026, to submit their bids. The project will be implemented on a 440-hectare site in Bazma under a concession regime.
The project combines a 300 MW photovoltaic capacity with a Battery Energy Storage System (BESS) of 150 MW power and 540 MWh storage capacity. The storage system is a crucial component of the project, allowing for the conservation of electricity produced during periods of high solar production and its restitution when production decreases or demand increases. The project's technical and financial requirements are significant, and the Ministry of Industry, Mines, and Energy is seeking promoters capable of implementing the project under a concession.
The call for tenders was launched in March, and the period for registration of interested candidates was extended until July 15. A new official publication dated September 4, 2026, confirmed the maintenance of the procedure and the deadline of October 14 for the reception of offers. The project is part of Tunisia's efforts to accelerate the development of renewable energies, and its association of photovoltaic production and storage constitutes an important test for the integration of large-scale solar capacities into the Tunisian electrical network.
The identity of the promoters who will submit a bid remains unknown, as the public documents consulted do not provide a public list of registered companies or groups preparing an offer. The absence of an official list makes it impossible to attribute the project to an operator or confirm the participation of a specific international group. The project's concession regime and storage component add technical and financial requirements to the photovoltaic power plant.
The Bazma project is a significant development in Tunisia's renewable energy sector, which is expected to benefit from the integration of large-scale solar capacities into the electrical network. The project's storage system will enable the conservation of excess energy produced during periods of high solar production and its restitution during periods of high demand. The project's completion is expected to contribute to Tunisia's efforts to increase its renewable energy production.
The next concrete step in the project's development will be the opening of bids after the deadline fixed for October 14, 2026. The project's implementation will require significant technical and financial resources, and the selected promoter will need to demonstrate its ability to implement the project under a concession regime. The project's success will depend on the promoter's ability to integrate the photovoltaic and storage components effectively.
The Bazma solar project is a strategic project for Tunisia's energy sector, and its completion is expected to have a positive impact on the country's renewable energy production. The project's association of photovoltaic production and storage constitutes an important milestone in the development of Tunisia's renewable energy sector. The project's implementation will require careful planning and execution to ensure its successful completion.
