On 16 August, the 50 MW tower CSP plant in Gonghe, operated by the Hainan Regional O&M Center of PowerChina New Energy, generated 1.0133 GWh in a single day—the highest daily output since the plant entered commercial service.
Since the beginning of this year, the plant has focused on the twin goals of “safeguarding generation and maximizing benefit.” Guided by the execution philosophy of “promise it, do it, and do it well,” every generation task has been broken down to each post and every process, creating an end-to-end responsibility system. Through routine, whole-process hazard screening and precise risk assessments, the plant carries out comprehensive “health checks” on critical links such as equipment operation and system interfaces, fortifying the safety line and laying a solid foundation for high-efficiency generation while ensuring stable output from the source. Targeted internal training and cross-position technical exchanges are used to spark employees’ innovative thinking and hands-on skills, forging an O&M team that is technically proficient and operationally disciplined—providing strong talent support for efficient operations. At the same time, refined management is deepened in line with seasonal irradiance patterns and equipment performance, further unlocking potential for higher quality and greater efficiency, and contributing additional clean energy to the “dual-carbon” goals.
Located in the Gonghe County Ecological Solar Power Generation Park, Hainan Prefecture, Qinghai Province, the Power China Gonghe 50 MW tower CSP plant sits at an average altitude of 2,880 m and covers 2.12 km². It is PowerChina’s first CSP project wholly invested, designed, constructed, and operated by the group itself. Construction began on 6 May 2018, and the plant was synchronized to the grid on 19 September 2019—the fourth demonstration CSP plant in China to reach this milestone. On 22 April 2021 the project passed the national demonstration acceptance. In 2024 the plant generated 85.7125 GWh, and on 11 May 2025 it set a then-record single-day output of 0.91875 GWh.
