- Project Overview
- The Sharavathi Pumped Storage Project (PSP) is a major renewable energy initiative by Karnataka Power Corporation Limited (KPCL).
- Planned capacity: 2,000 MW (one of India’s largest PSPs).
- Location: Jog Falls area, Shivamogga district, Karnataka.
- Estimated cost: ₹8,000 – ₹9,000 crore.

- Purpose & Need
- To meet Karnataka’s growing peak power demand.
- To store excess renewable energy (mainly solar and wind) during non-peak hours.
- Works like a giant battery: water is pumped to the upper reservoir when excess power is available and released to generate electricity when demand is high.
- Design & Technology
- Upper Reservoir: Talakalale balancing reservoir.
- Lower Reservoir: Existing Sharavathi tailrace and Linganamakki dam waters.
- Will use pumped hydro storage technology, proven as the most efficient large-scale energy storage solution worldwide.
- Environmental & Ecological Concerns
- The project is proposed inside the Sharavathi valley, part of the Western Ghats (UNESCO World Heritage site).
- Requires diversion of forest land (~150 hectares).
- Risk to biodiversity: rare flora & fauna, evergreen forest cover, and wildlife corridors.
- Environmentalists fear impact on Jog Falls tourism, river ecosystems, and endangered species.
- Government’s Stand
- Karnataka govt argues that the project is essential for renewable integration and reducing dependency on coal.
- Claims to use existing reservoirs to minimize deforestation.
- Promises strict environmental safeguards.
- Public & Expert Opinions
- Supporters: Say it will help stabilize Karnataka’s power grid, make renewable energy more reliable, and boost the state’s economy.
- Opponents: Stress the irreversible damage to forests, wildlife, and local water resources. Suggest alternatives like battery storage, solar-wind hybrids, and upgrading existing hydel plants.
- Current Status (2025)
- The project is still under review and clearance stages.
- Facing legal and public objections due to environmental concerns.
- If approved, it will take 6–7 years to complete after construction begins.
- Broader Significance
- Part of India’s goal to reach 500 GW renewable energy by 2030.
- Will make Karnataka a leader in pumped storage hydropower in India.
- Seen as a test case balancing energy security vs. environmental protection.
In simple words:
The Sharavathi Pumped Storage Project is a massive “water battery” planned in the Western Ghats of Karnataka to store renewable energy and meet rising electricity demand. While it promises clean power and grid stability, it also threatens fragile forests and biodiversity. The debate continues between development needs and ecological conservation.
