The feasibility study will assess project costs, battery energy storage systems (BESS), reservoir depth, and overall site suitability
Tamil Nadu Green Energy Corporation Limited has proposed setting up the state’s first floating solar photovoltaic (FPV) plants across seven locations, marking a key step toward expanding renewable energy capacity.
The identified sites include the Mettur, Bhavanisagar, Vaigai, Red Hills and Sathanoor reservoirs, along with Avalanche, a TNGECL-owned asset. The initiative aims to optimise the use of waterbodies while increasing clean power generation in the state.
TNGECL has approached the Water Resources Department (WRD) for permission to utilise these reservoirs and has appointed a private firm to conduct feasibility studies and provide technical support. An official announcement is expected after the Model Code of Conduct concludes.
According to a senior TNGECL official, the Union government has estimated Tamil Nadu’s floating solar potential at up to 3,000 MW across 57 reservoirs. As part of the pilot phase, the project will be implemented at seven sites with a combined capacity of 100 MW.
The feasibility study will assess project costs, battery energy storage systems (BESS), reservoir depth, and overall site suitability. Implementation will commence once necessary approvals are obtained.
Officials noted that floating solar projects typically require about 20% higher investment compared to ground-mounted solar installations, but offer advantages such as efficient land use and reduced water evaporation.
