**China is cementing its dominance in global hydropower, driven by the massive Yarlung Tsangpo project and a strategic pivot to pumped storage.** The Yarlung Tsangpo project, expected to be the world's largest with 60GW installed capacity and triple the output of the Three Gorges Dam, began construction in July last year at a cost of $176.4 billion. However, IHA president Malcolm Turnbull warned that such megaprojects face immense delays, noting that Moore's law does not apply to digging holes, and the development has sparked geopolitical tensions with downstream nations like India over water rights.</p><p class="summary-lead">**The IHA's 2026 World Hydropower Outlook reveals China has over 300GW of hydropower under construction, with 217.5GW dedicated to pumped storage.** Unlike traditional dams, pumped hydro systems operate as closed-loop reservoirs at different elevations, avoiding cross-border river disruptions. China is installing roughly 7GW of pumped storage annually, a pace that dwarfs the global average, reflecting a strategic shift from capacity expansion toward grid flexibility and integration of renewables.</p><p class="summary-lead">**The rapid acceleration of pumped storage globally is the defining story of this year's outlook, as countries recognize the need for large-scale flexibility.** India has outlined plans to expand pumped storage to 100GW by 2035, while the East Asia and Pacific region added 7.6GW last year. IHA CEO Eddie Rich emphasized that the clean energy transition cannot succeed without such storage, signaling a global race to build grid-stabilizing infrastructure.</p><p class="summary-lead">**What to watch next:**
Key Takeaways
- China's Yarlung Tsangpo project, at 60GW, will be the world's largest hydropower plant but faces years of construction and geopolitical friction with India.
- China is installing 7GW of pumped storage annually, far outpacing the global average, as part of a strategic shift toward grid flexibility.
- The IHA warns that large hydropower megaprojects suffer from chronic delays, even in China, due to the physical limits of construction.
- Global pumped storage capacity is accelerating rapidly, with India targeting 100GW by 2035 to support renewable integration.
Insights & Analysis
- China's focus on pumped storage over traditional dams signals a move from pure generation to system-level energy management, positioning it as the backbone of a renewables-heavy grid.
- The geopolitical tension over the Yarlung Tsangpo could escalate into a broader water-security conflict in South Asia, potentially reshaping regional energy diplomacy.
