{"title":"India Targets 100GW Pumped‑Storage by 2035‑36 Amid China’s Hydropower Surge","excerpt":"India’s ambitious plan to install 100 gigawatts of pumped‑storage hydropower by 2035‑36 faces a stark contrast with China’s massive 300‑plus gigawatt push. The 2026 Global Hydropower Outlook by the International Hydropower Association highlights the gap and India’s recent 4,267‑MW addition in 2025.","body_html":"<p>India is setting its sights on a 100‑gigawatt pumped‑storage capacity by 2035‑36, a move that underscores the nation’s commitment to expanding its renewable energy portfolio. Yet, the country’s plans are dwarfed by China’s aggressive hydropower expansion, which the International Hydropower Association (IHA) reports is already under construction at over 300 GW, including 218 GW of pumped storage.</p>n<h2>Hydropower in the Global Landscape</h2>n<p>The IHA’s 2026 Global Hydropower Outlook, released on 24 June 2026, paints a clear picture of East Asia’s dominance. China leads the pack, with a pipeline that includes:</p>n<ul>n<li>More than 300 GW of new hydropower capacity under construction.</li>n<li>218 GW of pumped‑storage projects, positioning China as the world’s largest player in this sector.</li>n</ul>n<p>India, while trailing behind China, is making significant strides within the Central and South Asian region.</p>n<h2>India’s Recent Hydropower Growth</h2>n<p>In 2025, India added a remarkable 4,267 MW of hydropower capacity, making it the top performer in its region. The growth was led by several new projects across the country’s diverse river basins.</p>n<p>For comparison, other regional players added:</p>n<ul>n<li>Ne pal – 468 MW</li>n<li>Israel – 344 MW</li>n</ul>n<h2>What Is Pumped‑Storage Hydropower?</h2>n<p>Pumped‑storage hydropower is often referred to as a “water battery.” It works by:</p>n<ul>n<li>Storing excess electricity by pumping water uphill to a reservoir during periods of low demand.</li>n<li>Releasing the water to generate electricity when demand spikes.</li>n<li>Providing grid stability, load balancing, and backup power.</li>n</ul>n<h2>India’s 100GW Target: Why It Matters</h2>n<p>India’s 100 GW pumped‑storage goal is part of a broader strategy to:</p>n<ul>n<li>Reduce reliance on fossil fuels.</li>n<li>Enhance grid resilience amid increasing renewable penetration.</li>n<li>Support the country’s climate commitments and energy security.</li>n</ul>n<p>Achieving this target will require:</p>n<ul>n<li>Strategic site selection to minimize environmental impact.</li>n<li>Robust financing mechanisms and public‑private partnerships.</li>n<li>Advanced technology adoption and skilled workforce development.</li>n</ul>n<h2>Challenges Ahead</h2>n<p>While the ambition is clear, India faces several hurdles:</p>n<ul>n<li><strong>Land and environmental clearances:</strong> Large reservoirs can affect local ecosystems and communities.</li>n<li><strong>Financing:</strong> Pumped‑storage projects are capital intensive, demanding long‑term investment.</li>n<li><strong>Technical expertise:</strong> Scaling up to 100 GW will require significant upgrades in engineering and construction capabilities.</li>n</ul>n<h2>Comparing India and China</h2>n<p>China’s lead is not just in capacity but also in construction speed. The country’s 218 GW of pumped storage under construction dwarfs India’s current projects and sets a high benchmark for the region.</p>n<p>India’s path forward will involve:</p>n<ul>n<li>Learning from China’s project execution models.</li>n<li>Leveraging international collaborations for technology transfer.</li>n<li>Focusing on sustainable development to
