The “CSP +” integrated project in Dunhuang developed by China Energy Investment Corporation (via its Longyuan Power arm) is currently in a full sprint toward grid connection by June 30 this year.
The 100 MW molten salt linear Fresnel CSP project within the integrated system has set clear milestones for its construction progress:
- By April 10: Production of qualified demineralized water
- By April 20: Completion of high-pressure pipeline flushing
- By June 30: First grid connection of the unit (current core objective)
In terms of overall construction progress:
- All main civil works have been completed
- Core equipment has been fully installed
- The four major steam pipelines are in place
- Key facilities—including the air-cooled condenser system, molten salt storage tanks, and solar collector field—have been completed and are now operational
- Thermal control instrumentation wiring and water treatment commissioning are progressing in parallel
- The molten salt system is advancing steadily, with the installation of the molten salt main pipeline reaching 90% completion
The Dunhuang “CSP +” integrated energy project is one of the landmark projects under China’s first batch of large-scale “wind–solar–desert” renewable energy bases. Located in Dunhuang, Gansu Province, the project represents a total investment of over RMB 4.1 billion and is jointly developed by:
- China Energy Longyuan Power (Gansu Branch)
- Lanzhou Dacheng Technology
The overall project includes:
- 480 MW wind power
- 100 MW molten salt linear Fresnel CSP
- 120 MW photovoltaic power
The CSP component is undertaken under a PC (procurement-construction) contract by Gansu Installation Group.
