China Develops Giant Battery Projects in Sichuan Mountains for Renewable Energy Storage
China is advancing large-scale energy storage solutions by converting mountainous sites into massive battery systems. Projects like the 4,300-meter Daofu hydroelectric plant aim for 2.1 GW power capacity and daily storage of 12.6 million kWh, while the Lianghekou project will reach a total capacity of 4.2 GW. These installations utilize pumped storage technology, enabling efficient energy storage and stabilization of the national grid amid renewable energy fluctuations, with significant investments of around 15.1 billion yuan for Daofu alone.

China is transforming its mountainous regions into large-scale energy storage systems to address renewable energy intermittency. Projects such as the Daofu plant, with a capacity of 2.1 GW and a daily storage capability of 12.6 million kWh, and the Lianghekou project, totaling 4.2 GW, exemplify this strategy.
Utilizing pumped storage technology, these facilities pump water to higher reservoirs during surplus energy periods and release it to generate electricity when demand rises. The Daofu project involves an investment of approximately 15.1 billion yuan. The construction at high altitudes presents unique engineering challenges, emphasizing China's commitment to energy transition and security.
