Sharavathi Pumped Storage Project In Karnataka To Boost Renewable Energy Storage Capacity

The Sharavathi Pumped Storage Project (PSP) in Karnataka's Shivamogga district is set to enhance India's renewable energy storage. State Energy Minister K.J. George highlighted its importance, calling it "critical for the green energy transition" and a "practical solution to ensure clean power when people need it most." This project aims to address the gap in renewable energy storage capabilities.

India's ambitious goal is to achieve 500 gigawatts (GW) of power generation from non-fossil fuel sources by 2030, as announced at the COP26 climate summit. By June 2025, the country had reached 235.7 GW of non-fossil fuel capacity, making up 49% of its total installed power generation capacity. The government is committed to expanding renewable capacity and strengthening grid infrastructure.

Renewable Energy Storage

Karnataka Power Corporation Limited (KPCL) officials emphasised that energy storage is crucial for the country's renewable energy chain. A senior KPCL planner stated, "Storage is no longer optional. We are producing enough renewable energy, but unless we can store and dispatch it efficiently, we will remain dependent on coal." This highlights the project's significance in reducing reliance on fossil fuels.

The Sharavathi PSP will harness surplus solar power generated during daylight hours to pump water from a lower reservoir to an upper one. At night or during peak demand periods, this stored water will be released through turbines to generate electricity, ensuring a continuous supply of renewable energy.

Environmental Considerations

Officials have designed the project to minimise environmental impact by using the existing Sharavathi–Linganamakki reservoir system. It requires only limited new infrastructure like tunnels and underground facilities. Only eight families will be affected by the project, and all will receive full rehabilitation support.

Karnataka stands out as a leader in renewable energy generation with over 16 GW of installed solar and wind capacity—nearly triple what it was in 2016. This growth underscores the state's commitment to clean energy and its role in India's broader renewable strategy.

The government's focus remains on promoting investments in clean energy to meet its 2030 target. By enhancing storage capabilities through projects like Sharavathi PSP, India aims to ensure a stable and sustainable power supply while reducing carbon emissions.
