Fortis Energy preparing to build solar-battery hybrid power plant in Serbia

Fortis Energy has obtained a construction permit for a solar park of 270 MW on the territory of the city of Sremska Mitrovica in Serbia, Mayor Branislav Nedimović said. The company plans to include a battery energy storage system (BESS) of 36 MWh.

Turkey-based Fortis Energy bought a solar power project in Serbia last year, which would have a 180 MW grid connection. At the time, the company announced that it also planned a battery energy storage system of 36 MWh. Chief Operational Officer Velimir Gavrilović said in May, at Belgrade Energy Forum (BEF 2025) that the projects Noćaj 1 and Noćaj 2 are nearing a ready-to-build status.

After his recent meeting with the representatives of Fortis Energy, Mayor of Sremska Mitrovica Branislav Nedimović said the company has obtained a construction permit for the solar park. The transmission permit is expected within three months, and the works are beginning in the spring, he revealed. Sremska Mitrovica is a city west of Belgrade.

The location is on private land just south of the river Sava, toward Drenovac village in the Mačva area, Nedimović asserted. He said the solar power plant’s capacity would be 270 MW.

In May, the company signed a contract for the connection of its planned solar park Erdevik in Šid, a municipality bordering Sremska Mitrovica. The plan is to install 110 MW in peak capacity, with a BESS system of 31.2 MWh.

The developer and engineering, procurement and construction (EPC) contractor is working on wind power projects Vranje, Gornjak and Juhor.

The company has five biogas facilities of 21 MW altogether, including its Dolovo system in Serbia.

Last year in North Macedonia, Fortis Energy commissioned a photovoltaic plant of 79.9 MW in peak capacity in Oslomej in North Macedonia. The grid capacity is 68.7 MW.

The company said in February that it contracted the construction of a BESS of 62 MW at the same location. It opted for lithium ion batteries of 104 MWh in total capacity.
