Fortis Energy gets permit to build 36 MWh BESS for Serbia’s Nocaj 1 site

Fortis Energy is set to begin installing a 36 MWh battery energy storage system (BESS) at the Nocaj 1 solar plant in Sremska Mitrovica, Serbia, in the second quarter of 2026. This will be the first phase of Fortis’s wider 270 MW solar‑plus‑storage development, which comprises Nocaj 1, Nocaj 2, and a previously acquired 180 MW solar site in the same region.

Once completed, the hybrid complex will be, according to the company, “one of the largest hybrid energy plants in Central and Eastern Europe”. The project is located south of the Sava River near the village of Drenovac, in the Macva area, some 50 km to the west of Belgrade.

Turkish firm Kontrolmatik Technologies was selected to design and build the 90 MW solar facility at Nocaj 1, including the 36 MWh BESS supplied by its storage subsidiary Pomega Energy Storage Technologies. Fortis has also secured a grid‑connection permit for 180 MW (AC), a key technical milestone that underpins the long‑term expansion of the Nocaj complex.

The Istanbul‑based developer, active across Turkey, the Netherlands and the Balkans, says its renewable energy pipeline now exceeds 3 GW. Fortis is targeting 1.2 GW of installed capacity by 2027 as part of its “Green Baseload” strategy, which aims to replace traditional fossil‑fuel plants with a mix of solar, wind, biogas and battery storage systems.

Serbia is pushing ahead with its energy transition, adding a record 134.3 MW of solar in 2025, largely driven by through large-scale plants being approved and developed in rapid time.
