Recently, civil work of Shouhang Dunhuang 2nd phase of 100MW molten salt CSP tower project was successfully completed and entered the installation process.
The CSP Plant started its preliminary work in 2014. The foundation stone laying ceremony was held at the end of 2015. In November 2016, it entered the phase of comprehensive construction. The project is expected to be connected to the grid by the end of 2018.
As one of China 1st batch of 20 pilot CSP projects, the 2nd phase CSP project owns the world’s largest stand-alone solar field – over 10,000 heliostat basics.

| Project Overview
Shouhang Dunhuang 100MW Molten Salt Tower CSP Plant（hereinafter referred to as “the project”） is one of the 1st batch of 20 pilot CSP projects in China and being developed with a steady progress. Belonging to the second phase of Shouhang’s Dunhuang CSP plan (Phase one 10MW completed), the project is the largest molten salt tower CSP plant during construction period in China and its equipped solar field will be the largest one in the world when it’s completed.
|Location||Solar Industry Park, inthe west of Qili Town, Dunhuang|
|Investment||CNY 3 billion|
|Annual generating capacity||3500h|
|Solar field area||12, 300, 00 sq. m.(Over 12,000 heliostats; tower height: 263 meters)|
Developer and investor: Beijing Shouhang IHW Resources Saving Technology Company Ltd (Shouhang)
In 2014, Shouhang started commercialized CSP project development and entered into scale industry stage. Shouhang devotes into systematic R&D of concentrator system, receiver, thermal energy storage system, heat exchange system and thermal electricity integration control system. By now, Shouhang successfully achieved small and middle size testing systems for tower, Parabolic Trough and dish CSP projects.
Main participants and biding situation:
The main raw materials of the project are steel, aluminum product and glass, which are purchased from domestic suppliers by bidding. Core components as heliostat, control device, receiver and air cooling system are provided by Shouhang. Ensival Moret, Flowserve, GE, Siemens and Man are part of the key suppliers of the remaining equipment.
