Greenko, Adani, and JSW to Develop Majority of India’s 51 GW Pumped Storage Projects

India is set to significantly expand its energy storage infrastructure, with Greenko, Adani Green Energy, and JSW Energy leading the development of a majority of the country’s 51.24 GW pumped storage capacity, projected to be completed by 2032. This initiative is part of India’s broader effort to enhance grid reliability while integrating a growing share of renewable energy.

Key States at the Forefront

According to the Central Electricity Authority (CEA), more than half of this planned capacity will be developed in Andhra Pradesh and Maharashtra. Andhra Pradesh is expected to add 16 GW, while Maharashtra will contribute 13 GW. These states offer the geographic and infrastructure advantages necessary for large-scale pumped hydro development, making them vital to India’s energy transition goals.

Greenko’s Storage Leadership

Hyderabad-based Greenko is making substantial strides in this sector, with a major 3.3 GW pumped storage project currently underway in Tamil Nadu, covering districts like Tirupathur, Salem, and Tiruvannamalai. Another key project is being developed in Madhya Pradesh’s Neemuch district, initially planned at 1.44 GW but now expanded to 1.92 GW. The company has set a target of achieving 50 GWh of energy storage capacity by 2025 and intends to double that in the years to follow.

JSW Energy’s Expanding Commitment

JSW Energy, through its arm JSW Neo Energy, has entered into a long-term 40-year agreement with Uttar Pradesh Power Corporation Ltd (UPPCL) for a 1.5 GW pumped storage project in the Sonbhadra district. This project, designed for eight hours of energy discharge per day, is expected to be operational within six years. With this development, JSW’s total committed storage portfolio has grown to 28.3 GWh, the majority of which (26.4 GWh) is pumped storage, bringing the company closer to its 2030 goal of 40 GWh.

Adani’s Expanding Footprint

Adani Green Energy is also aggressively building pumped storage capacity, particularly in Maharashtra. The company is working on several projects in locations like Patgaon, Warasgaon, Malshej Ghat, and Tarali. These efforts are central to Adani’s larger ambition of achieving 50 GW of total renewable capacity by 2030.

Scaling Up National Storage Capacity

At present, India’s pumped storage capacity is under 5 GW. The plan to scale it up to over 51 GW by 2032 marks a dramatic increase and a critical step toward achieving the country’s clean energy targets. Out of the 51.24 GW, around 10 GW of projects are already under construction, with the CEA projecting that 39 new projects will be commissioned by 2032.

Importance of Pumped Storage for Grid Stability

Pumped storage technology uses two water reservoirs at different elevations to store energy by pumping water to the upper reservoir when electricity demand is low and releasing it to generate electricity during peak demand. This method is highly effective for stabilizing the grid, especially as India increases its reliance on variable renewable sources like solar and wind.

This massive pumped storage buildout will play a key role in helping India meet its ambitious goal of installing 500 GW of non-fossil fuel-based power by 2030. It also reflects a strong push to improve energy security and support the country’s climate commitments.

In summary, Greenko, Adani, and JSW are not just building infrastructure—they are driving a fundamental transformation in India’s energy landscape, ensuring the country can reliably integrate renewable energy on a large scale.
