Chinese power equipment provider, Sieyuan Electric Co Ltd. has secured energy storage agreements totaling over 4.5 GWh in Romania. The latest agreement has signed on March 18, includes a 2.5 GWh BESS project with a Romanian energy developer, following earlier GWh-scale contracts secured within the same month.
The agreements cover the deployment of turnkey battery energy storage systems (BESS) designed to meet European technical and regulatory requirements. These systems integrate multiple components, including lithium battery packs, power conversion systems, transformers, and medium-voltage switchgear and energy management systems. The configurations are structured to support grid operations by enabling controlled energy discharge, system balancing and compatibility with regional grid codes.
Romania has been identified as an active market for energy storage development, supported by increasing integration of variable renewable energy sources and evolving grid requirements. The contracted projects align with the need for flexible infrastructure capable of managing fluctuations in electricity supply and demand. Large-scale BESS installations are being deployed to provide services such as frequency regulation, peak load management and reserve capacity within the national grid.
Sieyuan Electric’s energy storage systems referenced in these agreements have undergone verification processes by international organizations, including BloombergNEF, DNV and TÜV. These assessments relate to system performance, safety standards and operational reliability, which are key considerations for deployment across European markets. The inclusion of such systems reflects alignment with established certification and compliance frameworks required for grid-connected infrastructure.
The company stated that it has accumulated over 10 GWh of global BESS project experience to date, spanning multiple regions and applications. Romania is being treated as a regional market within its broader European expansion strategy, with ongoing collaboration involving local developers and project stakeholders. The agreements indicate a continuation of project development activity in the country during 2026.
Sieyuan Electric’s broader operations include power transmission and distribution equipment, energy storage systems, automotive electronics and power asset management. Its project portfolio reflects participation in grid infrastructure development across both domestic and international markets. The Romania agreements contribute to its current project pipeline and reflect ongoing activity in large-scale energy storage deployment across Europe.
