The project, undertaken by China Construction Second Engineering Bureau Ltd., a subsidiary of China State Construction Engineering Corporation, is located at an average altitude of 3,600 meters and spans 8,000 mu (approximately 5.3 square kilometers). It consists of 76 photovoltaic array zones, with a total of 450,000 monocrystalline bifacial photovoltaic modules installed. The facility includes a 220 kV booster station and a 50 MW energy storage power station, with a total installed capacity of 250 MW.

The project’s 50 MW energy storage station is the first grid-forming energy storage power station in Sichuan Province, capable of charging or discharging 50,000 kWh within two hours. By integrating energy storage batteries with photovoltaic power generation equipment, the station functions as a self-sustaining microgrid with automatic charging and discharging capabilities. This system not only mitigates the intermittency of renewable energy generation but also enhances the stability of the power grid in remote areas.

Once fully connected to grid, the project is expected to generate 450 million kWh annually, further optimizing the regional energy structure and strengthening power supply security.
