Advanced Grid-Side Energy Storage Solutions, System Integration & Successful Grid Operation in Bulgaria

As a global provider of electrical infrastructure solutions, Yawei Transformer delivers not only equipment manufacturing but also complete grid-side energy storage system integration, including battery PACK systems, BMS, PCS, Energy Management System (EMS), thermal management, fire protection systems, and grid dispatch communication interfaces.

This Bulgaria-based 115kV energy storage project demonstrates our capability in full-system integration, international project execution, and utility-scale energy infrastructure deployment. From equipment delivery and installation guidance to system commissioning, all stages were supervised by our senior engineering team to ensure precise and reliable execution.

The project successfully achieved grid connection and stable operation, delivering key functions such as frequency regulation, peak shaving, and renewable energy absorption. It significantly improved the flexibility and stability of the Bulgarian power grid, reducing fluctuations from wind and photovoltaic generation.

This milestone reflects Yawei Transformer’s strong capability in delivering turnkey energy storage solutions for modern power systems across Europe and global EPC markets.
