Floating solar could unlock a new chapter for India’s reservoirs
India’s new PM Surya Sarovar Yojana targets 5 GW of floating solar and at least 10 GWh of co-located storage across suitable water bodies.
A third surface for solar.
Alongside land and rooftops, suitable reservoirs and industrial ponds can become sites for renewable generation. Floating photovoltaic systems allow water infrastructure to retain its primary use while hosting solar modules above it.
This can reduce competition for scarce land, but only where site conditions and environmental safeguards make the project appropriate.
Floating solar and storage are being planned together.
The Pradhan Mantri Surya Sarovar Yojana has an outlay of ₹5,070 crore and envisages 5,000 MW of floating solar with at least two hours of co-located storage, or 10,000 MWh. NISE has estimated approximately 102.18 GWp of floating-solar potential across suitable inland water bodies.
Storage matters because it separates the moment solar electricity is generated from the moment it is consumed, making the output more flexible for the grid.
Its engineering is different.
Floating solar is not a conventional ground-mounted project placed on water. Water levels, anchoring, wind, electrical safety, maintenance access, moisture exposure and local environmental impacts all need to be assessed before deployment.
