Yumen Xinneng 50MW molten salt tower CSP plant was officially selected as one of China 1st batch of CSP pilot projects in September 2016. It is the only pilot project taking innovative beam down CSP tower technology.

Suzhou Thvom Technology Co., Ltd (shorted as Thvom) occupied 85% share of the project. And recently as Thvom announced, Shanghai Electric, China leading power energy state-owned company, acquired some stock equity of Thvom and became the biggest shareholder with 15% stock capital.

As CSP Focus reported earlier, Shanghai Electric was awarded the EPC contractor of the well-known Dubai 700MW CSP parabolic trough + tower project. This acquisition is actually a further step for Shanghai Electric to develop solar power business in China and abroad.

With total investment of RMB 1.78 billion, Yumen Xinneng 50MW molten salt tower CSP project takes beam-down CSP technology with 15 mirror field modules, each module consists of 17MWth solar filed and one beam-down tower, totaling 50MWe. Also one 9-hour molten salt thermal storage system & steam turbine set are included in the project.

The project broke ground in July 2017, and news said that the No.1 Module had taken shape, the whole project is expected to be finished by December, 2018.

 Project Overview

Yumen Xinneng 50MW molten salt tower CSP plant was officially selected as one of China 1st batch of CSP pilot projects in September 2016. With total investment of RMB 1.78 billion, the project is expected to be completed in 2 years. The project is located in Zhengjiashawo CSP Park, 5km far from new downtown of Yumen city, Gansu Province. The 50MW project takes beam-down CSP technology with 15 mirror field modules, and one 9-hour molten salt thermal storage system & steam turbine set. The annual generating capacity is under load of 4328 hours. The project broke ground in July 2017, and is expected to be finished by December, 2018.

As recognized by CSP industry players, the Direct Normal Irradiance (DNI) should be above 1,700kW.h/㎡, and the DNI in Yumen is around 1,901 kW.h/㎡, indicating that Yumen is rich in solar resources and a great place for building CSP plants.
