1.6 GWh GigaBattery Breaks Ground in Germany
In a major boost for Germany's energy infrastructure, HyperStrong and LEAG have officially broken ground on the Boxberg 400 GigaBattery project in Saxony. This massive battery energy storage system (BESS) boasts a staggering capacity of 1.6 GWh (1,600 MWh). The project represents a significant step in repurposing former coal regions for advanced clean energy technologies, providing crucial long-duration storage to balance the country's renewable grid.
Eastern Europe's Largest Operational BESS in Bulgaria
Meanwhile, in Eastern Europe, the Burgas BESS project in Bulgaria has commenced operations, marking a new regional record. Executed by European EPC and O&M contractor Solarpro Technology, the facility has a total capacity of 602 MWh, making it the largest operational battery energy storage facility in Eastern Europe. This project increases Bulgaria's total energy storage capacity by 10% and provides essential balancing capabilities for large-scale wind and solar generation.
Advanced PCS Integration in Burgas
The Burgas project relies on highly advanced power conversion technology. Sineng Electric supplied its 6.9 MW central PCS MV turnkey stations, integrating four EH-1725-HA-UD central PCS units for the 150 MW/300 MWh segment of the system. This solution supports flexible 1/2/4/6/8-hour storage durations and reduces parallel connections by 50%. It delivers critical grid services including peak shaving, load shifting, Frequency Containment Reserves (FCR), and automatic Frequency Restoration Reserves (aFRR).
