SESPA Sounds Alarm Over Ecological Impact
SESPA Opposes Sillahalla Pumped Hydro-Electric Project Amid Ecological Concerns: The Sillahalla Ecological Social Protection Association (SESPA) has strongly opposed the proposed Sillahalla Pumped Hydro-Electric Storage Project in Tamil Nadu’s Nilgiris district, warning of its severe impact on fragile ecosystems and agricultural communities. SESPA argues that the hydropower project, which involves constructing two dams connected by a 10 km tunnel, poses a significant threat to the region’s biodiversity and ecological stability, which are already under stress due to deforestation and climate change.
Project Details and Land Submergence Concerns
The project is planned to be developed within a cluster of 25 villages, making it a source of distress for local farming and tribal communities. SESPA has raised alarms that nearly 1,000 acres of farmland and 500 acres of forest land are at risk of submersion. This includes valuable agricultural zones and elephant corridors, which are critical to both food security and wildlife conservation. The large-scale transformation of land is likely to cause loss of livelihood, displacement, and long-term environmental degradation.
Fragility of the Nilgiris: A Red Flag for Development
The Nilgiris region is classified as a highly eco-sensitive zone within the Western Ghats, a UNESCO World Heritage Site. Home to unique shola forests, endemic species, and indigenous tribes, the Nilgiris faces increasing threats from unregulated infrastructure projects. Environmentalists believe that any major intervention—like dams or tunnels—can cause irreversible damage through landslides, soil erosion, and groundwater disruption. The Sillahalla project, in particular, is feared to destabilize natural drainage patterns and endanger wildlife habitats.
Need for Alternatives and Inclusive Dialogue
SESPA is urging the Tamil Nadu government to reconsider the project’s approval and instead explore alternative renewable options such as solar micro-grids or community-based energy systems that don’t disrupt ecologies. The association has also called for a transparent Environmental Impact Assessment (EIA) and wider public consultation before moving forward. With increasing global emphasis on sustainable development, the case highlights the growing tension between clean energy goals and local ecological sustainability.
