Hanersun has announced the signing of an annual supply agreement with Bulgarian contractor Technoenergostroy for delivery of 12.65MWh of energy storage systems, supporting one of the country’s earliest storage projects under the EU subsidy scheme. The agreement marks a major step forward in Hanersun’s European strategy and highlights both companies’ shared commitment to accelerating energy transition in the region.
The agreement involves Hanersun supplying 55 units of its HNESS 230-L liquid-cooled energy storage system for the project’s initial phase. The system integrates lithium batteries, PCS, BMS and EMS and offers flexible scalability and intelligent control. Certified to EN IEC 61000, IEC 62619:2022 and UN38.3 standards, the product meets stringent EU safety and technical requirements, ensuring stable grid connection.
Hanersun’s HITOUCH 5N high-efficiency modules will continue to support the project’s ongoing development and, once operational, the PVESS solution will support peak shaving and load shifting, setting a potential benchmark for EU-subsidized energy storage projects.
