PM Surya Sarovar Yojana: India’s ₹5,070 Crore Push for Floating Solar
The Union Cabinet has approved the Pradhan Mantri Surya Sarovar Yojana, a ₹5,070-crore initiative to accelerate floating solar power across reservoirs and water bodies. The scheme aims to add 5,000 MW of capacity while integrating battery storage to improve grid reliability and support India’s clean energy transition.
What happened
The Union Cabinet has approved the Pradhan Mantri Surya Sarovar Yojana (PM-SSY), a ₹5,070-crore scheme designed to expand floating solar power across reservoirs, dams, industrial ponds, and other suitable water bodies.
The programme targets the installation of 5,000 MW of floating solar capacity and mandates a minimum of two hours of battery energy storage for supported projects, translating into at least 10,000 MWh of storage capacity across the scheme.
To encourage project development, the government will provide Central Financial Assistance (CFA) of ₹1 crore per MW after successful commissioning. Developers can also receive up to ₹50 lakh per project for preparatory activities such as bathymetric surveys, hydrographic studies, environmental assessments, and project planning.
Why it matters
India has one of the world’s largest untapped floating solar opportunities. According to assessments by the National Institute of Solar Energy (NISE), the country’s technical potential for floating solar is estimated at about 102.18 GWp, while actual installed capacity remains only a fraction of that potential.
Floating solar projects reduce pressure on scarce land resources by utilising existing water bodies, making them particularly valuable in densely populated states where acquiring large parcels of land for conventional solar parks is increasingly difficult. They can also reduce water evaporation from reservoirs while improving solar panel efficiency due to the cooling effect of water.
The scheme’s mandatory battery storage requirement marks another significant policy shift. By pairing solar generation with energy storage, projects will be better equipped to supply electricity beyond daylight hours, helping improve grid stability and support the growing integration of renewable energy into India’s power system.
Beyond energy generation, the government estimates the programme could help avoid around 10 million tonnes of carbon dioxide emissions annually while creating approximately 16,000–17,000 full-time-equivalent jobs across project development, construction, operations, and maintenance.
What’s next
The Solar Energy Corporation of India (SECI) is expected to oversee the implementation of the scheme, including project approvals and the disbursement of financial assistance. Developers will begin identifying suitable reservoirs and water bodies, conducting feasibility studies, and preparing projects for commissioning.
The pace of implementation will determine how quickly India can translate its vast floating solar potential into operational renewable energy capacity while strengthening energy storage infrastructure and advancing its long-term clean energy goals.
