SUPCON SOLAR Delingha 50MW CSP Plant
The plant is one of China's first batch of CSP Demonstration Projects, entitled as National Strategic and Emerging Industry Key Project by NDRC.
The plant, located in Delingha, Qinghai Province, is a molten salt tower CSP plant configured with 27135 sets of 20m2 heliostat. The designed electricity output is 146 GWh/year, which equals to the annual power demand of 80,000 households and can save 46,000 tons' standard coal, and reduce 121,000 tons' CO2 emission, which is economically and socially benefitting. The plant construction started in March, 2017, and was commissioned in December, 2018, and reach full-load operation in April, 2019. The major equipment run steadily and the indicators of the plant has exceeded their design parameters.
POWERCHINA Gonghe 50MW CSP Plant
The plant is one of China's first batch of CSP Demonstration Projects. SUPCON SOLAR is the technology and equipment provider of the solar island and is awarded with commissioning service for the whole plant and subsystems.
The plant, located in Gonghe County, Qinghai Province, is a molten salt tower CSP plant configured with 30016 sets of 20m2 heliostat to generate 156.9 GWh electricity annually.
SUPCON SOLAR Delingha 10MW CSP Plant
- China's 1st and world's 6th commercially operated Tower CSP plant (July, 2013)
- China's 1st and world's 3rd Molten Salt Tower CSP plant (August, 2016)
- China's 1st CSP plant awarded with Feed-in Tariff (1.2 RMB /kWh)
The plant is located in Delingha, Qinghai Province, which adopts twin tower design with DSG and molten salt receivers, configured with 21500 sets of 2m2 heliostat and 1000 sets of 20m2 size. Since operated in August 2016, the plant has been running stably, and the power generation is on steady growth. In 2018, the total electricity output against the predicted electricity output of the performance model achieved 96.75%, which is the top performance among its peers across the world.
