The project financing application by national utility Societe Tunisienne. Provision of a senior loan of up to EUR 40 million to Societe Tunisienne de L'Electricite et du Gaz (STEG), to finance the construction and development of a 50-MWac photovoltaic solar power plant, with a 20-MWh Battery Energy Storage System (BESS), and associated high-voltage transmission. French developer Voltalia will construct a 100 MW solar farm in Gabès province. A consortium of Norway's Scatec and Japan's Aeolus, a unit of Toyota Tsusho, will develop a 100 MW PV plant near Mazouna in Sidi Bouzid Governorate, all equiped with Battery Energy Storage System (BESS) Preliminary. solar PV and wind together accounting for nearly 70%. The integration of these variable energy sources into national energy grids will largely depend on storage technologies, and among them especially batteries, to provide the flexibility required to smooth the energy supply w ich expected to reach. This five-year program of US$430 million — including US$30 million in concessional financing from the Climate Investment Funds — aims to support the Government of Tunisia to deliver a sustainable, reliable, and affordable electricity supply by accelerating renewable energy deployment, strengthening. Tunisia has launched a groundbreaking subsidy program targeting energy storage systems, aiming to achieve 30% renewable energy integration by 2030. This policy directly addresses the nation's $200 million annual energy import costs while creating opportunities for: The government offers.
