The 25 MW / 55 MWh battery energy storage system (BESS) located in the municipality of Razlog, in southwestern Bulgaria, has begun its commercial operations. This significant milestone marks the system as the largest BESS project in Bulgaria to date, jointly developed by Kehua, the global expert in PV and ESS solutions, and Solarpro, the largest energy EPC company in Eastern Europe.
Project Overview
The largest energy storage project in Bulgaria, powered by Kehua’s energy storage solution, has a capacity of 25 MW / 55 MWh and is located in Razlog. The solution includes the Kehua BCS3450K-B-HUD/T PCS and an integrated medium-voltage transformer.
This project is located next to a 33 MWp solar power plant, seamlessly integrating into the grid of the transmission system operator (TSO). Kehua supplied the integrated 1500Vdc PCS solution and medium-voltage transformer, which can be applied in various applications such as peak shaving, frequency modulation, and auxiliary grid connection for new energy systems.
Solarpro plans to replicate the success of the Razlog project, leveraging its experience to advance the integration of highly reliable energy storage solutions in its Eastern Europe portfolio. This project sets a precedent for the future of the renewable energy sector in the region and highlights the key role that Kehua’s cutting-edge PCS innovations and Solarpro’s expertise in hybrid energy projects can play in the seamless integration of solar energy and energy storage.
Industry Impact and Future Outlook
Thanks to the collaborative efforts of industry leaders like Solarpro and Kehua, this project represents a significant step towards a more sustainable and resilient energy infrastructure. As the world’s leading energy storage provider, Kehua will continue to demonstrate its expertise in achieving sustainable energy transition programs and grid modernization to drive energy transition and combat climate change.
This advancement not only reinforces Bulgaria’s commitment to adopting renewable and sustainable technologies but also positions the country as a leader in the region for large-scale energy storage projects. The successful implementation of the BESS in Razlog is a testament to the potential of energy storage solutions to transform the energy infrastructure and ensure a more reliable and eco-friendly energy supply.
With the continued collaboration between Kehua and Solarpro, more innovative and impactful projects are expected to be developed in Eastern Europe, significantly contributing to the global goal of reducing carbon emissions and promoting environmental sustainability.
