- Sieyuan Electric Co., Ltd. is a Chinese company specializing in the development, manufacturing, and supply of power transmission and distribution equipment, energy storage systems, and automotive electronics. The company's core products include high-voltage gas-insulated switchgear (GIS) rated up to 550kV; oil-immersed power transformers up to 500kV; high-voltage circuit breakers and disconnecting switches; instrument transformers; power capacitors; electrical reactors; power quality treatment equipment such as dynamic reactive power compensation devices and harmonic treatment devices; and substation automation systems. Sieyuan also manufactures medium- and low-voltage switchgear, distribution transformers, and automotive low-voltage lithium-ion batteries, ultracapacitor modules, and intelligent power distribution systems. Sieyuan operates primarily in China with significant international project involvement including EPC projects overseas, supplying equipment for major infrastructure projects in countries like Mexico, Saudi Arabia, the Philippines, Belgium, Brazil, Italy, Ecuador, and Australia. The company targets the power transmission and distribution industry, energy storage sector, and automotive electronics market. Founded in 1991 and headquartered in Beijing, Sieyuan has expanded its technological footprint by acquiring a controlling stake in GMCC, a supercapacitor technology firm, in 2023. It invested approximately RMB 1 billion in 2024 to build a large-scale energy storage and power electronics manufacturing facility featuring production lines for energy storage packs and power conversion systems, among others. Recent strategic developments include expanding into low-voltage switchgear and residential PV inverter and battery energy storage systems since 2022, plus investments in power semiconductor research and automotive charging infrastructure. The company has formed partnerships and joint ventures, notably with Toshiba in transformer manufacturing, and with global OEMs in renewable energy integration, exemplified by collaboration with EDF Renewables and active participation in Australia's renewable energy projects. Sieyuan also emphasizes grid-forming energy storage solutions that enhance high-penetration renewable grids, underpinning its integrated "UHV grid plus energy storage" system offerings. Despite a 12-month exclusion from EIB-financed projects due to historical misconduct, it maintains a robust pipeline with significant contract wins in state grid tenders and continues to expand its upstream and downstream ecosystem in power equipment manufacturing and grid solutions. Sieyuan's product line complies with international standards including IEEE, IEC, and CSA, supporting its position as a leading supplier of reliable, efficient, and sustainable power equipment and energy storage solutions domestically and internationally. Its comprehensive portfolio supports ultrahigh-voltage direct current (UHVDC) projects, high-voltage transmission, and distribution networks supplemented by increasing capabilities in advanced energy storage and automotive electronics sectors.
