Chinese company Sermatec will implement an electricity storage project with a capacity of over 430 MWh, the Shanghai-based company announced in a press release published on its website on Monday. 

"From Bulgaria's sun-drenched Black Sea coast to the energy heartland of Eastern Europe, Chinese energy storage technology is playing an increasingly vital role in reshaping the continent's green energy landscape," the statement said. According to Sermatec, its project in Bulgaria represents a major breakthrough in the European market.

The project officially launched in August 2025 and is scheduled for delivery by the end of December, with grid connection and operation expected by March 2026. Sermatec will provide critical technological support and ongoing O&M services to help Bulgaria build a safer, more stable, and sustainable modern energy system — supporting the country's long-term energy transition goals.

"Located in Southeast Europe and blessed with abundant solar resources, Bulgaria has seen a rapid surge in PV installations. This boom brings an urgent need for flexibility and stability in the national energy system. Driven by favorable policies and generous subsidies, energy storage projects are rolling out at pace, playing a crucial role in optimizing Bulgaria's energy structure and significantly enhancing the security and resilience of its own and neighboring energy networks," the statement added.
