18 MW Singatalur-Huligudda Mini Hydel Project, Karnataka, India
Mini-Hydel at Tungabhadra
The project utilizes the hydropower of the Tungabhadra River at the Singatalur Barrage. Four generators with 4.5 MW each and a single head of up to 11 m are planned. The electricity will be fed into the KPTCL (Southern Regional Grid) network via GESCOM. Around 52,340 MWh are to be fed into the grid annually.
Project goals
Electricity from hydropower
The aim is to generate electricity using available hydropower and supply it to the public grid. The plant is located at the foot of the existing Singatalur Barrage and returns the water to the river after generating electricity. In this way, the project replaces fossil grid electricity. It is expected to reduce emissions by an average of 45,049 tCO2e per year.

Economic and social benefits
- 1
Employment
Around 300 jobs will be created during the construction phase and around 25 permanent positions during operation.
- 2
Local economy
Investments of around INR 670.54 million flow into the region and indirectly support local infrastructure such as roads, schools and basic services.
- 3
Environmental measures
INR 300,000 has been earmarked for soil conservation, INR 500,000 for greening/arboriculture and INR 1,000,000 for environmental and ecological maintenance.
- 4
Grid feed-in
The electricity generated (net approx. 52,340 MWh/year) is supplied to GESCOM and fed into the KPTCL grid.
Global climate significance
Emission reduction
The feed-in of renewable energy avoids an average of 45,049 tCO2e per year (grid feed-in x 0.860 tCO2/MWh).
Fossil replacement
Without the project, the same amount of electricity would be generated in the southern grid by existing and new fossil-fuel power plants.
Existing storage space
The plant uses an existing barrage without changing the storage volume; according to the methodology, project and leakage emissions are not to be recognized.
Reliable factors
The emission factor (combined margin) is determined ex-ante and is based on CEA data.
Conclusion
The Singatalur-Huligudda project reliably feeds hydropower into the South Indian grid. It replaces fossil generation and achieves measurable CO2 reductions according to documents. Implementation is based on ACM0002 and clear monitoring.
