Summary:

On 6 March 2026, Tunisia’s Ministry of Industry, Mines, and Energy launched the country’s first competitive tender for battery energy storage systems to strengthen grid stability and support the integration of renewable energy.  

The initiative aims to attract international firms to design, finance, construct, and operate large-scale battery facilities connected to Tunisia’s high-voltage transmission network. These systems will store surplus electricity generated by solar and wind projects and release it during periods of higher demand, helping to address the intermittency of renewable energy sources.  

The tender forms part of Tunisia’s broader energy strategy to increase the share of renewables in its electricity mix to 35 percent by 2030 while reducing dependence on imported natural gas. 

Outlook: 

As Tunisia has faced growing difficulties in electricity production in recent years, alongside increasing financial pressure on the national utility STEG, the launch of this tender represents a significant step in supporting the country’s long-term energy strategy. Rising oil prices due to the war in Iran are a prescient reminder of Tunisia’s current vulnerability to shocks in energy prices and the need for alternative solutions that increase resilience. 

Large-scale battery storage could help ease pressure on the national grid and reduce the likelihood of electricity shortages during peak consumption periods, particularly in the summer months when demand traditionally rises. 

The initiative is also likely to attract foreign investors and experienced international energy developers, as competitive infrastructure tenders often signal emerging opportunities for long-term participation in Tunisia’s expanding renewable energy sector.
