en.Wedoany.com Reported - The 300MW/600MWh shared new energy storage station project in Pingnan County, Guigang City, Guangxi, constructed by China Construction Eighth Engineering Division, has been successfully connected to the grid. This project is the first 100-megawatt-level shared new energy storage station in Guigang City and a key new energy project under Guangxi's "14th Five-Year Plan."

Guangxi has a high dependence on external energy sources, with a relatively large share of traditional energy consumption. The Pingnan shared new energy storage station has a total investment of 724 million yuan, covering an area of approximately 33,000 square meters. It is equipped with 120 sets of energy storage battery containers and 60 inverter-boost integrated cabins, with a storage capacity of 600 MWh and a daily storage capacity of about 600,000 kWh. The project also includes the construction of a 220kV step-up substation and power transmission lines.

The project absorbs surplus electricity during periods of high wind and solar power generation for storage, releases stored electricity during peak load periods to smooth peak-valley differences, and stabilizes the grid load through flexible peak-shaving capabilities, ensuring the safety of local industrial, agricultural, and residential electricity use.

The construction team completed preliminary work such as site preparation, personnel assignment, and large equipment coordination in just seven days. Located in a hilly terrain with variable weather, the team implemented staggered and off-peak construction schedules, strictly controlled the quality of each process, and successfully ensured the seamless transition between civil construction and equipment installation.

The project uses high-performance, environmentally friendly lithium iron phosphate energy storage equipment to enhance the storage and consumption capacity of clean energy. The construction site strictly adhered to green construction standards, controlling environmental indicators such as dust, noise, and construction wastewater.

Substation bay project was completed from project initiation to grid connection in just six months. The construction team completed key processes including 220kV equipment assembly, cable laying, main transformer commissioning, and energy storage module integration, strictly adhering to safety, quality, and schedule requirements.
