The Xiaojinchuan River Basin solar power base in Sichuan province began connecting its first photovoltaic arrays to the grid, marking progress in clean energy storage systems in high-altitude areas. Located at an elevation of 3,700 meters, the project has a total installed capacity of 160 megawatts and includes a 16 MW/32 MWh energy storage system.

It aims for an annual electricity output of 280 million kilowatt-hours, sufficient for 140,000 households. The project will save 87,000 metric tons of coal and reduce CO2 emissions by around 262,500 tons annually. It integrates with a pumped-storage power station and three hydropower stations, with all arrays to be fully connected by the end of February.
