en.Wedoany.com Reported - Germany's Siemens Energy AG, through its subsidiary Siemens Energy Gas Turbine Components (Jiangsu) Co., Ltd. (referred to as "Yixing Factory"), held a 10th anniversary celebration at its factory in Yixing City, Jiangsu Province, China, on June 9, 2026, and signed an agreement with the Yixing municipal government for capital increase and production expansion. During the event, the factory also held a delivery ceremony for the 700th blade set and the 100th casting set. According to the plan, the new component production capacity of the Yixing Factory will increase by over 30% in the next three years, while the maintenance component capacity will double.
Siemens Energy is one of the world's leading energy technology companies, with operations covering gas turbines, steam turbines, generators, power transmission, and hydrogen energy. Established in April 2016, the Yixing Factory is Siemens Energy's manufacturing base for heavy-duty gas turbine core components in China. After a decade of development, the factory has become Siemens Energy's only manufacturing base for heavy-duty gas turbine core high-temperature hot gas path components outside Europe, and the world's only one-stop turbine blade processing and repair center. The factory now offers a complete service capability covering new part supply, repair and refurbishment, and spare parts.
According to disclosures from the Yixing Municipal Propaganda Department and the local government, this capital increase and production expansion agreement will focus on expanding the gas turbine blade production workshop and upgrading advanced manufacturing equipment. In October last year, Siemens Energy made an additional investment in the Yixing Factory, introducing advanced equipment and optimizing production processes. Yao Zhenguo, Senior Vice President of Siemens Energy Global and President of Greater China, stated that the Yixing Factory has been committed to promoting the full localization of core high-temperature gas turbine blades since its inception, shouldering the dual mission of serving both the local Chinese and global markets. Leveraging the industrial foundation of the Yangtze River Delta region in high-end equipment, new materials, and new energy, as well as the advantages of processing and manufacturing talent, the Yixing Factory has gradually become a key link in the regional industrial ecosystem and energy equipment supply chain.
Over the past decade, the Yixing Factory has introduced world-leading turbine blade manufacturing technology to China, filling the gap in the mass production of high-end gas turbine core components in the domestic market. According to industry information, turbine blades are the core components of gas turbines and a major bottleneck restricting global gas turbine deliveries. Stefan Becher, Global Vice President of Siemens Energy and Head of the Blade Business Unit for the Large Power Generation Division of the Gas Power Generation Group, stated that the core advantage of the Yixing Factory lies in its strong and stable partnerships. Through close collaboration, the factory has elevated blade delivery cycles to a globally leading level. As of 2025, Siemens Energy's gas turbine orders reached 26 GW, a year-on-year increase of 94%, with an order value of up to 23 billion euros. This capital increase and production expansion will help further enhance the Yixing Factory's production capacity and delivery capabilities in the global supply chain.
