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.
