The Northernmost Solar Thermal Power Plant in China Begins Operations
China's first solar thermal power station in Northeast China has started operation, marking the northernmost concentrated solar power (CSP) plant in the country. Located in Dalian, Jilin Province, the project has a capacity of 100 megawatts. Watch the video report.
This 100-megawatt solar thermal power station is expected to serve as a replicable model for similar projects in regions with harsh climatic conditions.
The solar thermal power station is equipped with a molten salt thermal storage system capable of storing heat for up to 8 hours, enabling safe and stable electricity generation around the clock.
Solar thermal power plants use large arrays of heliostats to focus sunlight onto a central receiver tower, converting solar energy into thermal energy for later use in power generation.
The heliostat array consists of 19,667 high-precision mirrors with a total reflective area of approximately 590,000 square meters. These mirrors continuously track the sun, reflecting sunlight onto a receiver located 210 meters above ground level. The molten salt inside the receiver is heated to 565 degrees Celsius before being transferred to the thermal storage system for storage.
Due to lower-than-expected heat loss from the storage tanks, the stored thermal energy can not only be used for power generation on the same day but also, depending on weather conditions, for electricity production the following day or even later.
