Yumen Xinneng 50MW molten salt tower CSP plant was officially selected as one of China 1st batch of CSP pilot projects in September 2016, and has been under continous development and construction since the the break-ground on June 8th, 2017.
It is expected that No.1-3 Modules will be completed and connected to the grid at the end of next month in September 2019.
It is the only pilot project taking innovative beam down CSP tower technology and also will be the first large-scale commercial CSP project in the world taking beam-down CSP tower route.
With total investment of RMB 1.79 billion, Yumen Xinneng 50MW molten salt tower CSP project is made of 15 mirror field Modules, and each module consists of 17MWth solar filed and one beam-down tower, totaling 50MWe. One 9-hour molten salt thermal storage system & steam turbine set are also equipped in the project.
As Xinchen CSP Technology Co., Ltd, the Project Subcontractor of Energy Collecting and Storage System said earlier on the progress:
No.1 Module has been fully completed and commissioned;
No. 2 module is under construction, with the secondary reflection tower being lifted, and the majority of heliostats installed;
Modules 3-10 are undergoing basic civil engineering and steel structure and heliostats installation;
Main equipment such as steam turbine and generator installed and commissioned.
Take a look on the progress and milestones:
● Sept.30, 2019 (expected), Modules No.1-3 connected to the grid
● July, 2019, Module No.1 tested and molten salt was heated to 570℃; Heliostats of Module No.2 almost installed; Modules No.3-10 under construction
● March, 2019, steam turbine & steam generation equipment installed
● Aug.5th, 2018, main transformer installed
● April, 2018, foundation of steam turbine started construction; Modules No.2-5 started construction
● March, 2018, overall installation of Module No.1 completed
● Dec.7, 2017, molten salt TES started construction
● September, 2017, designing plan reviewed
● Jun.8, 2017, officially broke ground
● Dec.16, 2016, feasibility study meeting held
Suzhou Thvom Technology Co., Ltd (Thvom) acquired 85% share of the project in 2017, and was jointly invested by China Shanghai Electric in 2018.
Three Chinese partners and sub-company are playing key roles in the project technology, EPC and solar field equipment including China Sinogy Electric Engineering Co., Ltd (CSECC), Jiangsu XinChen CSP Technology Co., Ltd (XinChen) and Shanghai Parasol Renewable Energy Company (Parasol).
In terms of the equipment and service providers, Chinese local manufacturers like Luyang, Shanghai Turbine Works, Dongfang Boiler are working for the project by providing thermal insulation, steam turbine and steam generator.
Overseas companies including Ruhrpumpen, MICC, Schneider Electric, Flexim and Krohne provide some of the key products like molten salt pump, heat tracing, DCS and flow meters.
