Local Environmental Conditions

Hami is a city located in Xinjiang Uygur Autonomous Region of China. Its environment and climate conditions are characterized by its location in a continental desert climate zone, which means it experiences distinct seasons with extremes in temperature and limited precipitation, but has abundant sun radiation.

Lessons Learned

The CEEC Hami Solar project is the first project using the new STELLIO heliostats developed by MASERMIC and SBP Sonne. This new technology can improve performance and efficiency of the solar field. The project also use 45000 pieces of electronic equipment for automation and communication indicating the significance of robust electronic systems in managing a large scale solar fields. The MASERMIC advanced control software contributes to the smoother project operation by allowing integral management of the solar field. The success of this project pave the way for the development of new solar power plants project in China.
