Sermatec's Significant Power Storage Initiative in Bulgaria

On August 4, 2025, Sermatec made waves in the energy sector by securing a substantial energy storage project in Bulgaria, boasting a capacity of over 430 MWh. This landmark achievement positions the company as a key player in the ongoing energy transition across Eastern Europe, a region increasingly shifting towards sustainable energy solutions.

The project, situated along the sun-kissed Black Sea coast, represents a vital step in Europe’s green energy landscape, powered by innovative Chinese energy storage technology. As the continent rapidly transforms its energy sources, such technological breakthroughs are crucial in supporting the ambitious climate goals set by European nations.

The Project's Technical Framework

Sermatec will provide an integrated energy storage solution with a complete lifecycle, enhancing the project's efficiency and profitability. The system will charge during off-peak hours, harnessing low electricity prices, and discharge during peak hours to release stored energy back into the grid. This strategic operation maximizes price arbitrage, a critical factor that not only shortens the project's return period but also enhances overall investment returns.

Employing a dual technological upgrade—modular design and long-life battery technologies paired with precise charge/discharge interval management—Sermatec ensures the system maintains stable, high-performance operations even in demanding conditions. This reliability lays a robust foundation for effective long-term peak and drop arbitrage, thereby ensuring consistent economic returns throughout the project's lifespan.

The project officially commenced in August 2025, with plans for completion by the end of December, aiming for grid connection and operational commencement by March 2026. Sermatec is set to offer critical technological support and ongoing operational and maintenance services to aid Bulgaria in building a safer, more stable, and sustainable modern energy system, aligning with the country's long-term energy transformation goals.

Strengthening Competitive Advantage

The successful signing of this Bulgarian energy project underscores Sermatec's growing global competitiveness in market penetration, technical capabilities, and supply chain delivery. The company has established its European headquarters in Frankfurt, Germany, and set up a production base in Málaga, Spain, with a capacity of 3 GWh, thereby constructing a comprehensive value chain encompassing research and development, manufacturing, and maintenance services.

Sermatec offers cost-optimized solutions backed by advanced energy storage technologies and extensive project experience. Their offerings ensure longer life, superior system efficiency, and reduced operation and maintenance costs, perfectly aligning with international clients' focus on long-term value and ROI.

Recognized as a level 1 global supplier of energy storage systems by BloombergNEF for seven consecutive quarters, Sermatec continues to deliver reliable quality and timely supply.

A Catalyst for Change

This strategic partnership not only injects renewed momentum into Eastern Europe's transition to clean energy but also strengthens the foundations for Chinese-European green cooperation. As Europe accelerates its energy transformation, companies like Sermatec—armed with high-quality systemic solutions—become indispensable forces in shaping a sustainable global energy future.
