PM Surya Sarovar Yojana: 5,000 MW floating solar with storage

PM Surya Sarovar Yojana: what happened?

Solar parks need large tracts of land, and land is scarce and contested. Floating solar puts the panels on water instead: dams, reservoirs and industrial ponds. States also need help to meet peak demand. So PM-SSY ties every floating plant to storage of at least two hours.

• The scheme follows a National Institute of Solar Energy (NISE) estimate of about 102.18 GWp of floating solar potential.
• Feasibility support covers bathymetry and hydrography surveys, environmental studies and other preparatory work.
• All States and Union Territories can benefit.
• Expected gains: about 10 million tonnes less CO2 a year and 16,000 to 17,000 full-time equivalent jobs.
• It should push domestic manufacturing of floats, PV cells, modules and storage systems.

What is floating solar?

• Solar photovoltaic panels mounted on floatation systems on a water body.
• PM-SSY targets existing reservoirs and industrial ponds, so no new land is needed.
• Bathymetry and hydrography assessments come first, as part of the feasibility studies.
• Co-located storage means the storage system sits at the same project site.

Where does it fit in India’s solar story?

• Solar capacity grew from about 3 GW in 2014 to 162.15 GW by 30 June 2026, the PIB backgrounder of 2 August says.
• India added 44.61 GW of solar in FY 2025-26, nearly double the 23.83 GW of FY 2024-25.
• At COP26 in Glasgow India set the Panchamrit goals: 500 GW non-fossil capacity by 2030 and net zero by 2070.
• PM-SSY adds a storage-backed, land-free option to solar parks, rooftops and PM-KUSUM.

What do the numbers show?

At ₹1 crore per MW, support for 5,000 MW comes to ₹5,000 crore; the rest of the ₹5,070 crore covers studies and other items.

How will a PM-SSY project move?

1. State or developer picks a reservoir or industrial pond
2. Feasibility studies: up to ₹50 lakh support
3. Project sanctioned between FY 2026-27 and FY 2030-31
4. Plant with two-hour storage built and commissioned
5. ₹1 crore per MW released after commissioning

Why does PM Surya Sarovar Yojana matter?

What are the challenges in PM Surya Sarovar Yojana?

• Only about 700 MW exists today; scaling seven-fold in five years is a big jump.
• Storage adds cost, and support comes only after commissioning, so developers must fund the build first.
• Each water body needs depth and environmental studies before work starts.
• Reservoirs are owned by different agencies, so coordination with States is needed.

What should be done next on PM Surya Sarovar Yojana?

• Map reservoirs and ponds State by State from the NISE assessment.
• Speed up feasibility studies with the ₹50 lakh support.
• Tie storage dispatch to evening peak demand.
• Build a domestic supply chain for floats and batteries.

What can Prelims ask on PM Surya Sarovar Yojana?

• PM-SSY: approved 31 July 2026; ₹5,070 crore; 5,000 MW floating solar.
• Storage: minimum two hours (10,000 MWh), co-located.
• CFA: ₹1 crore per MW after commissioning; up to ₹50 lakh per project for studies.
• NISE potential: about 102.18 GWp; present floating solar: about 700 MW.
• Sanctions: FY 2026-27 to FY 2030-31.
