Turkish developer Fortis Energy has secured a construction permit for a 270 MWp solar power plant combined with a 72 MWh battery energy storage system (BESS) near Sremska Mitrovica, in the village of Drenovac, south of the Sava River. The project also holds a grid connection permit for 180 MW (AC).

Construction is expected to begin in the second quarter of 2026, positioning the facility as a key contributor to Serbia’s growing clean energy capacity. Once operational, it will significantly strengthen the country’s energy resilience and reduce dependence on fossil fuels.

Fortis Energy currently has a development pipeline exceeding 2.5 GW of renewable projects and aims to reach 1.2 GW of installed capacity by 2027. The company’s long-term strategy centres on building an integrated clean energy portfolio that combines solar, wind, and biogas power with advanced storage systems to ensure stability and flexibility in electricity supply.

The Sremska Mitrovica project underlines both Serbia’s and Fortis Energy’s commitment to accelerating the energy transition in Southeast Europe.
