Pumped storage project
Context
Karnataka’s fourth pumped storage project (PSP) has been officially proposed in the Chittapur taluk of Kalaburagi district.
- A private entity, Bengaluru-based Cerulean Energy Solutions Pvt Limited, has submitted a proposal seeking land and environmental clearances to construct the facility.
Key Specifications of the Kalaburagi PSP
- Power Capacity: Plans to generate 300 MW of clean energy to support grid stability.
- Land Requirement: Requested 747 acres of total land in Sankanoor village, which includes 65 acres of forest land.
- Water Resource: Requires a one-time lifting of 243 TMC (thousand million cubic feet) of water from the Bhima River, located 12 km away. The water will continuously recirculate between the upper and lower reservoirs.
- Energy Efficiency: Expected cycle efficiency is projected to hover around 80%.
- Grid Integration: A 220 KV double-circuit transmission line will connect the project to the Karnataka Power Transmission Corporation Limited (KPTCL) Shahabad substation to evacuate or supply electricity.
About Three Pumped Storage
- Sharavathi Pumped Storage Project (2,000 MW)
This is planned to be India’s largest pumped storage facility, located on the border of the Shivamogga and Uttara Kannada districts.
- Executing Agency: Karnataka Power Corporation Limited (KPCL).
- Mechanism: It will move water between two massive, already existing reservoirs—using the Talakalale Dam as the upper reservoir and the Gerusoppa Dam as the lower reservoir.
- Current Hurdles:
- An expert committee under the Union Ministry of Environment, Forest and Climate Change has withheld approval due to its footprint inside the eco-sensitive Sharavathi Valley Lion-tailed Macaque Wildlife Sanctuary. However, the state government remains firm on acquiring clearances to push it forward.
- Saundatti Pumped Storage Project (1,600 MW)
Located in the Saundatti taluk of the Belagavi district, this is a massive, grid-scale private venture.
- Executing Agency: Greenko Group
- Mechanism: Unlike Sharavathi, this is primarily an off-stream project. It uses the existing Renuka Sagar Reservoir (on the Malaprabha River) as its lower pool and is building a brand-new upper reservoir in a nearby natural depression. It continuously recirculates 1 TMC of water.
- Current Status: Under active civil and hydro-mechanical construction by infrastructure firms. It is on track for a targeted commissioning window around December 2027
- JSW Neo Energy Pumped Storage Project (1,000 MW)
This project was awarded via a competitive tariff-based bidding process managed by the state’s power procurement agencies.
- Executing Agency: JSW Neo Energy (a subsidiary of JSW Energy).
- Mechanism: It functions as a standalone long-duration storage system designed to discharge 8,000 MWh of stored energy (1,000 MW over an 8-hour peak block).
- Current Status: The project is in its planning, land allotment, and techno-commercial permitting phases, with multi-hundred megawatt power purchase agreements (PPAs) backing its integration into the state grid.

JSW Neo | Selected sites across state | 1,000 MW | Private (JSW Energy) | Closed-loop off-stream reservoirs |
Kalaburagi (Proposed) | Kalaburagi | 300 MW | Private (Cerulean Energy) | Bhima River (one-time lifting) |
KWIN City
Context
Karnataka has officially invited Luxembourg’s companies, universities, and innovation agencies to partner in the development of KWIN City, a landmark 5,800-acre knowledge and innovation megacity.
Key Areas of Collaboration
- Advanced Technology: Promoting research and development (R&D) in Artificial Intelligence (AI), FinTech, space technology, and digital transformation.
- Industrial Expertise: Utilizing Luxembourg’s specialized skills in precision engineering, steel, automotive components, and clean/green energy.
- Academic Partnerships: Inviting Luxembourgish universities to collaborate on institutional research and set up frameworks within the new city hub.
What is KWIN City?
- KWIN City (Knowledge, Wellbeing, and Innovation City) is a massive, forward-looking industrial township spearheaded by the Karnataka Industrial Areas Development Board (KIADB)
- Location: Strategically being developed between Dabaspete and Doddaballapura, situated right in the high-growth corridor near North Bengaluru and the Kempegowda International Airport.
- Scale: Spread across roughly 5,800 acres of land.
- Objective: Designed to decentralize industrial growth away from overcrowded areas of central Bengaluru, building a green-energy, state-of-the-art alternative for tech hubs, health sectors, and advanced manufacturing units.
Existing Economic Ties
- The relationship between the two regions is already backed by prominent corporate footprints:
- Luxembourg in Karnataka: The advanced engineering firm Ceratizit operates a specialized manufacturing presence in Karnataka to produce industrial cutting materials.
- Karnataka in Luxembourg: Major Bengaluru-headquartered IT multinationals like Infosys and Wipro run established, critical operations inside Luxembourg.
