Shanghai Sermatec Energy Technology Co., Ltd. has won a contract to supply and install a system at a high‑solar‑yield site. The facility stores power when demand is low and production is high, then releases it during peak periods to take advantage of price differences between off‑peak and peak electricity.
Bulgaria project and timeline
The project began in August 2025 and is scheduled for completion by December 2025, with grid connection and commissioning planned for March 2026. Sermatec will provide technical support as well as operation and maintenance services.

European growth and manufacturing plans
The contract in Bulgaria is not Sermatec’s only recent deal. In March 2025, the company signed an agreement with a Polish power developer to deliver 200 MWh of battery storage. At the 11th Energy Strategy Summit in Romania on 24 June 2025, Sermatec’s country sales manager highlighted the role of energy storage in supporting Romania’s renewable capacity, which is projected to rise from 20 MWh in 2023 to 0.5 GW by 2025.
Sermatec builds European factory and value chain
Sermatec is establishing a fully integrated European value chain, with an office in Frankfurt, Germany, and its first battery factory outside China in Humilladero, Spain. The plant will produce high‑performance lithium batteries for large‑scale renewable energy storage, with an annual capacity of 3 to 5 GWh, and will cover research and development, manufacturing and services. Commissioning is scheduled to take place no later than 2027.
Caroline White of SegenSolar: “Poland is emerging as a key market”
With major projects in Bulgaria and Poland, strategic expansion in Eastern Europe, and a new manufacturing base in Spain, Sermatec is positioning itself to play a central role in Europe’s evolving energy storage market in the years ahead. (mg)
