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.
