100MW/200MWh - Hunan Province, China
Project introduction: the project is currently China's single area is larger, more curvature, the existing building construction technology is better aluminum alloy structure building. At the same time, it is also a relatively complex large-span aluminum alloy reticulated shell structure project. After the top mesh is completed, it will integrate 5A-level office, commercial supporting facilities, star hotels and other functional development.

Case Introduction
Energy storage capacity: 100MW/200MWh
Application characteristics: large temperature difference between day and night, high temperature application
The AC side capacity of the energy storage power station of this project is 100MW/200MWh, using lithium iron phosphate lithium batteries. The energy storage system adopts the outdoor layout of prefabricated cabins, with 31 3.125MW/6.3MWh energy storage units, 62 sets of energy storage battery prefabricated cabins and 31 sets of PCS and step-up transformer integrated equipment. The power station is designed with 2 110kV on-load voltage-changing transformers with a single unit capacity of 63MVA, and the 110kV distribution device uses outdoor GIS equipment. The total investment of the project is 430 million yuan. It started on March 8, 2023 and was connected to the grid at full capacity on June 28.
After the completion of this project, it can effectively alleviate the power supply pressure of Hunan and Hengyang power grids, improve the peak load regulation capacity of power grids, and improve the economic efficiency of power grid operation. It can also greatly improve the power grid's ability to accept renewable energy, reduce the phenomenon of wind and solar abandonment in low valleys, and create favorable conditions for vigorously developing renewable energy. This energy storage power station can also give full play to the regional coordination and sharing role of energy storage stations, effectively promote the development of new energy projects in the region, and help build a new power system in Hunan.
