On March 18, 2026, the Delingha 350 MW Concentrated Solar Power (CSP) Demonstration Project, developed by Qinghai Zhongkong Solar Power Co., Ltd., officially resumed full-scale construction in the solar (PV & CSP) industrial park in Delingha, Qinghai Province.
At the project site, construction activities are now underway in an orderly manner. The completion of the receiver tower foundation excavation marks a key milestone and signals that the project has entered an accelerated construction phase for 2026.
With construction fully back on track, the project is set to move into peak activity across several major work fronts, including the main structure of the receiver tower, roofing of the main power block, installation of molten salt storage tanks, and heliostat field support structures. The project team is leveraging the favorable spring construction season to optimize scheduling and execution, aiming to meet all key milestones on time and lay a solid foundation for subsequent commissioning and grid connection.
As one of the first batch of CSP demonstration projects approved by the Qinghai Provincial Energy Administration, the Delingha project is invested and developed by Zhejiang Zhongguang New Energy Technology Co., Ltd., with a total investment of approximately RMB 5.567 billion.
The project features a low-position molten salt tank thermal storage configuration and is equipped with a new generation of high-precision 37 m² heliostats. With 14 hours of thermal energy storage capacity, the plant is expected to generate approximately 985 GWh of electricity annually—enough to meet the yearly power demand of around 500,000 households. It is also projected to save approximately 295,000 tonnes of standard coal and reduce CO₂ emissions by about 870,000 tonnes per year.
Upon completion, the project will significantly enhance renewable energy integration and improve the efficiency of clean energy utilization, serving as a benchmark for the development of China’s clean energy sector.
The project’s feasibility study report was approved on March 21, 2025, and construction officially commenced on December 28, 2025. Its successful commissioning is expected to play a vital role in optimizing the regional energy mix, strengthening grid flexibility, and supporting Qinghai’s ambition to become a national hub for clean energy development.
