Fortis Energy, a Turkish renewable energy developer, has received a pivotal construction permit for a major solar-plus-storage power project in Serbia. The 270 MW photovoltaic plant, coupled with a 72 MWh battery storage system, marks one of the Balkans’ most significant strides toward clean electricity generation. Construction is expected to begin in mid-2026.
Key Takeaways
- Fortis Energy receives construction permit for a 270 MW solar and 72 MWh storage project in Serbia.
- The site is located near Sremska Mitrovica, south of the Sava River, west of Belgrade.
- Construction is scheduled to start in the second quarter of 2026.
- Project will be among the largest of its kind in Southeast Europe.
- Fortis is expanding its renewables portfolio across Central and Eastern Europe.
Project Details and Location
The approved facility will be situated near Sremska Mitrovica, just south of the Sava River and west of Serbia’s capital, Belgrade. This new installation comprises a 270 MW photovoltaic (PV) plant integrated with a 72 MWh battery energy storage system (BESS), designed to support grid stability and enhance renewable output reliability.
A grid connection permit has also been granted for 180 MW of AC capacity, ensuring the project will be able to transmit the generated electricity efficiently. The combination of solar generation and storage will help Serbia meet its growing energy demands while reducing reliance on fossil fuels.
Regional and Industry Impact
Once operational, the project will become a landmark example of solar-plus-storage integration in Southeast Europe, supporting Serbia’s ambitions to grow its renewable energy sector. According to market analyses, Serbia’s installed solar power capacity stood at 281 MW in mid-2025; this single project will nearly double the country’s current capacity upon completion.
The development aligns with recent Serbian government initiatives aiming for greater adoption of renewables and battery storage. In the last year, the country has advanced agreements for multiple large-scale solar facilities, including targets for several hundred megawatts of new storage.
Fortis Energy’s Broader Strategy
Fortis Energy has a robust pipeline of approximately 2.5 GW in various stages of development across Central and Eastern Europe, with the ambition to bring 1.2 GW online by 2027. While most of the company’s existing assets are in Türkiye, its growing presence in the Balkans and surrounding region highlights the increasing interest from international investors and operators in Southeast European renewables.
Previously, Fortis acquired the Serbian project from an undisclosed party in 2024 and has since increased the battery component to 72 MWh from an earlier plan of 36 MWh, boosting the site’s flexibility and value to the national grid.
Looking Ahead
Serbia’s energy landscape is rapidly changing, with a pipeline of gigawatt-scale solar developments and new storage facilities. The Fortis Energy project not only cements the country’s status as an emerging market for green technology but is also likely to stimulate further investment and innovation in the region. As construction commences in 2026, it will be closely watched as a benchmark for similar utility-scale endeavors throughout Southeast Europe.
