As the project owner and developer China Guangdong Nuclear Power (CGN)announced earlier, CGN Delingha 50MW parabolic trough concentrated solar power (CSP) plant, China first large-scale commercial CSP project, was successfully connected to the grid in the evening of June 30.
It is absolutely a great milestone for China CSP industry, which entitled China the 8th country in the world owning large-scale commercial CSP project. And as CSP Focus keeps reporting, the CGN Delingha plant is also amongst China 1st batch of 20 pilot projects (4 cancelled for now) and now the first with completion.
The project was officially broken ground in the year of 2014, and the only CSP project in China getting loan from Asian Development Bank. With total investment of RMB 1.938 billion, the project is equipped with 9 hours molten salt thermal energy storage.
Chinese companies Beijing Shouhang IHW Energy Saving & SEPCOII and Shandong Sunway Petrochemical Engineering Co., Ltd joined the project as EPCs of solar field and HTF&TES respectively. Other local involvers include Dongfang Turbine, Harbin Turbine, Wuxi Chemical Equipment, Co., Ltd etc. And global leading CSP companies like TSK, IDOM, sbp, Rioglass, Solutia, Sulzer also provided components and services for CGN Delingha CSP project.
