en.Wedoany.com Reported - The EPC tender announcement for the Ruoqiang Nengchuang 200MW/800MWh grid-forming energy storage project was released on July 15.

The tenderer is Ruoqiang County Nengchuang New Energy Co., Ltd., with a project funding source of self-raised funds totaling 700 million RMB.

Located in Ruoqiang County, Xinjiang, the project will construct a new 200MW/800MWh grid-forming independent energy storage station, utilizing lithium iron phosphate electrochemical energy storage technology. Supporting works include the construction of a 220kV step-up substation, collector lines, on-site roads, living quarters, and other ancillary facilities. The 220kV outgoing transmission line is not within the scope of this tender.

The project plans to adopt a grid-forming energy storage solution. The lithium iron phosphate electrochemical energy storage system is tentatively designed to use 314Ah cells, with a 1P416S battery cluster configuration, each cluster having a capacity of 418.00kWh. Every 12 battery clusters form one 20-foot energy storage battery container, with a single container capacity of 5015.96kWh. Each set of 4 battery containers is paired with one 5MW converter-booster integrated unit, which includes a 5250kVA dry-type transformer, four 1250kW bidirectional converters, and associated auxiliary facilities. The project will be equipped with a total of 40 sets of 5MW converter-booster integrated units and 160 sets of 5MWh lithium iron phosphate electrochemical energy storage battery containers. The energy storage system uses the 35kV/0.69kV step-up transformer as the basic access unit. After being collected via 8 circuits of 35kV collector lines, it connects to the 35kV busbar of the 220kV step-up substation. After voltage step-up through the main transformer, it connects to the Ruoqiang 750kV substation via one 220kV line, achieving the integration and grid connection of the energy storage system.

Joint bids are not accepted for this tender.
