On the edge of Taklamakan, the desert is being redefined. On June 5th, the bidding results of the 600000 kilowatt photovoltaic sand control project in Yecheng County, Xinlong, Xinjiang were announced. China Railway 15th Bureau Group Co., Ltd. Southwest Engineering Co., Ltd. and Shandong Environmental Energy Design Institute Co., Ltd. jointly won the bid for 1.828 billion yuan, equivalent to a unit price of about 2.54 yuan/W. This is not just a power station, but also an ecological project of on board power generation and off board sand control.

Super engineering in the desert

The project is located in Yecheng County, Kashgar Prefecture, with a rated installed capacity of 600MW, actual installed capacity of 720MWp, capacity ratio of 1.2, and supporting energy storage capacity of 60MW/120MWh. The bidding party is Xinjiang Xinlong Kaisheng New Energy Co., Ltd., which adopts the EPC general contracting mode. The scope covers survey and design, 220kV substation, collection line, external transmission line and end-to-end transformation, all construction and installation projects in the photovoltaic area, as well as the entire process of temporary roads, land compensation, land reclamation, etc., from feasibility study report to completion acceptance and quality assurance.

Integrated construction design

China Railway 15th Bureau Group Co., Ltd. Southwest Company has teamed up with Shandong Environmental Energy Design Institute to form a consortium, opening up a closed loop of construction and design capabilities. In photovoltaic sand control projects, the design end needs to accurately match the spacing between photovoltaic panels and wind and sand fixation requirements, while the construction end needs to cope with large-scale ground power station construction in desert environments. It is difficult for a single enterprise to fully understand the entire chain at the same time. The consortium model is becoming mainstream in Xinjiang's new energy projects.

The contract amount is 1.828 billion yuan, with a price of 2.54 yuan per watt, which is within a reasonable range in the current large-scale photovoltaic EPC market. The real highlight is not the price, but the trend: photovoltaic sand control is moving from pilot to large-scale, and the Yecheng project is just a microcosm of the construction of the Shage Desert Base in Xinjiang. When the desert turns into a power station, the power station holds onto the quicksand, and this road will only become wider and wider.Editor/Cheng Liting
