On February 2, YOTAI successfully signed a 135MW/270MWh standalone battery energy storage project with a leading Romanian energy group-Metropolitan Energy SRL in Bucharest. The project is expected to become one of the largest standalone energy storage developments in Romania to date and represents a key breakthrough for Chinese companies in the European independent energy storage market.This cooperation marks YOTAI′s strong entry into the core of Europe′s energy transition and demonstrates the company′s strategic commitment to deepening local market engagement while continuously expanding its long-term investment and presence across Europe.

（The agreement was signed by Mr. Robertino, Chairman of Metropolitan Energy SRL, and Mr. Chen Shuo, President of YOTAI, on behalf of both parties.）

As a key milestone in YOTAI′s global strategy, the project will be delivered in two phases, providing a fully customized standalone energy storage solution. The scope includes the company′s self-developed Ener Hexon® Aurora 5015 containerized liquid-cooled battery energy storage system, integrated step-up transformer and power conversion station, as well as a 110kV step-up substation.Upon commissioning, the project will enable millisecond-level response to grid frequency regulation requirements, mitigate the intermittency of renewable energy generation, and significantly enhance the grid′s capability to integrate clean energy while improving overall power supply reliability. In addition, it will help relieve grid load pressure and strengthen resilience against power shortages caused by extreme weather events, creating a sustainable and replicable″energy storage+renewables″development model for Southeast Europe.

At the signing ceremony, Mr. Chen Shuo, President of YOTAI, emphasized that the cooperation represents a strong partnership with a Romanian energy partner and a key step in the company′s deeper engagement in the European market and its regional energy transition strategy.

Since the full implementation of its global strategy in 2024, YOTAI has delivered more than 2,000 projects across 23 countries and regions worldwide. Looking ahead, the company plans to establish regional service centers and warehousing hubs in key markets including Romania, the Netherlands, and Kenya, further enhancing project delivery efficiency and operations and maintenance capabilities, while continuously deepening its participation and influence within the global new energy ecosystem.

The advancement of this project is underpinned by YOTAI′s forward-looking product portfolio and extensive experience across diverse application scenarios. Previously, the company introduced the Ener Hexon® Smart261L-CE intelligent liquid-cooled C&I ESS to key European markets. As one of the world′s first liquid-cooled energy storage systems to truly achieve ″zero condensation″, the product has demonstrated high reliability and outstanding performance, enabling large-scale deployment across multiple European countries. It has been widely applied in scenarios such as PV integration and virtual power plant (VPP) response, earning strong recognition in local markets.Building on this foundation, the Romania project further integrates YOTAI′s comprehensive capabilities in system integration, full-stack product development, intelligent power systems, and energy and carbon management. Together with local partners, the company will explore innovative business models for standalone energy storage operation, delivering a ″Leading Energy  Solutions″to support Europe′s energy transition.

From product supply to system delivery, and from energy management to scenario-based enablement, YOTAI remains committed to the values of professionalism, innovation, collaboration, and mutual success. Together with global partners, the company is building a more flexible, reliable, and green energy infrastructure, driving energy systems worldwide toward a steady transition to a net-zero future.
