How many energy storage power stations are there in Asia

With rapid urbanisation and industrialisation, the East Asia and Pacific region has been on a trajectory of rapidly rising energy demand. China continues to dominate hydropower development in the East Asia and Pacific region, adding 14.4GW of new installed capacity in 2024 to reach a total of 435.95GW.

In the central China region, the provinces of Zhejiang, Hubei, and Hunan possess the largest prospective capacities in the pipeline, with 95 GW across 79 projects. Moreover, 13 provinces that do not presently have any operating pumped storage facilities boast over 127 GW of prospective capacity.

China is the top-ranked country in terms of oper-ating PSH capacity with 50.7 GW, holding 30% of the world's total. This is roughly equivalent to the combined PSH capacity of all European countries. China's current share of global prospective capacity exceeds 80%, making it the primary country for the development of the pumped storage industry.

Market dynamics, technical developments and regulatory policies that could be decisive for energy storage deployment in Australia, Mainland China, Malaysia, Singapore, South Korea, Taiwan, Thailand and Vietnam. This white paper explores the opportunities, challenges and business cases.

PSH accounted for more than half of the new capacity, with 7.75GW added that year, bringing total installed PSH capacity to 58.69GW. With more than 200GW of PSH under construction or approved, China is on track to exceed its 2030 target of 120GW, potentially reaching 130GW by the end of the decade.

During conditions of abundant energy and run-of-river projects 75 megawatts (MW) or larger, shows that the Eastern Asia region represents 73% of current and future PSH capacity. Operating capacity within this region is currently dominated by China and Japan, and China is far and away the leader for prospective capacity.
