A Shift in Turkey’s Energy Landscape: First Utility-Scale Solar-Plus-Storage Plant Online
Developer Oze Grup has officially announced the commencement of operations at the Sivrihisar project in Eskisehir. This marks Turkey’s first grid-connected hybrid asset under the DGES framework, signaling the arrival of the “Controlled Green Power” era.
Located southwest of Ankara, the project utilizes high-efficiency synergy between solar PV and battery storage to solve the intermittency issues of traditional solar. Its operation provides a real-world template for building Turkey’s modern, flexible digital grid.
Unveiling the Core Tech: CATL’s EnerC Containerized Liquid-Cooling System
The technological heart of the plant is the CATL EnerC series, a containerized liquid-cooling BESS. With each unit boasting a capacity of 3.72 MWh, it represents one of the most competitive, high-integration, long-life solutions in the global market.
The EnerC system utilizes advanced liquid-cooling to maintain minimal temperature variance across cells, significantly enhancing safety and cycle life. This ensures high charging and discharging efficiency even in the arid, inland climate of Turkey.
Elite Supply Chain Synergy: A Commercial Benchmark Under the DGES Framework
The Sivrihisar project combines a 49.2 MWp solar capacity with 34.1 MWh of storage, perfectly aligning with Turkey’s Sustainable Finance Framework (DGES). Oze Grup has become the first developer to navigate the full licensing and provisional acceptance process.
The success stems from deep collaboration across the China-Turkey energy supply chain. PVI Enerji served as the lead EPC, while local contractors like Elin Enerji worked alongside CATL’s technical support to deliver this complex hybrid energy asset.
Market Bellwether: How Storage Tech is Reshaping Turkey’s Supply Chain
With this project’s integration, Turkey’s demand for high-efficiency storage is shifting from experimental phases to large-scale implementation. The entry of global tech giants like CATL is accelerating the upgrade of Turkey’s local integration and thermal management sectors.
Oze Grup stated that providing clean energy enhanced with storage is a concrete step toward a sustainable future. This “Solar + Liquid-Cooling Storage” model is expected to become the gold standard for Turkey’s upcoming gigawatt-scale storage tenders.
Conclusion: Starting a New Chapter in Uninterrupted Green Energy Supply
The commissioning of the Sivrihisar project proves the superior capability of large-scale battery systems in stabilizing grid frequency and smoothing power output. It is more than just a power plant; it is a gateway for Turkey to embrace cutting-edge battery tech.
As more efficient systems like EnerC are deployed, Turkey is poised to optimize its energy structure rapidly. This not only bolsters energy security but also offers a valuable “Turkey Case Study” for the global transition to clean energy.
