Overview
The Union Cabinet has cleared the PM-SSY, a programme to install 5,000 MW of FSPV capacity on Indian reservoirs. The scheme carries a total outlay of ₹5,070 crore and provides up to ₹1 crore per MW of CFA after commissioning.
Key Developments
- Each plant must be paired with at least two‑hour battery storage, totalling 10,000 MWh across the scheme.
- The SECI will implement the projects, attracting an estimated ₹28,500 crore of private investment.
- Floating solar is expected to reduce curtailment by shifting generation to evening peaks.
- Land requirement is minimal – only cabling corridors need land – addressing the acute land‑scarcity faced by ground‑mounted solar.
- The Centre will fund feasibility studies up to ₹50 lakh per site to de‑risk the technology for states.
Important Facts
India currently has about 0.7 GW of floating solar against a technical potential of 102 GW. The scheme’s cost is higher than ground‑mounted solar: ₹4.9–5.2 crore per MW for FSPV versus ₹3.9–4.2 crore for land‑based plants, a ~25 % premium. The mandatory battery adds ₹0.9–1.2 crore per MWh. Maharashtra (16.28 GWp) and Madhya Pradesh (14.89 GWp) hold the largest reservoir potential, followed by Karnataka, Odisha, Telangana and Gujarat.
Exam Relevance
The programme touches several GS papers. GS3 – Environment & Ecology because it expands renewable capacity while conserving land and water resources. GS3 – Economy as it involves large‑scale public‑private investment, central‑state financial transfers, and job creation (16,000–17,000 jobs). GS2 – Polity is relevant for understanding the federal‑state coordination mechanism through CFA and feasibility‑study grants. Finally, the scheme contributes to India’s climate commitments – the updated NDC and the Panchamrit target of 500 GW non‑fossil power by 2030.
Way Forward
States should identify suitable reservoirs, conduct the funded feasibility studies, and adopt adaptive mooring designs to manage water‑level fluctuations. The Union should streamline procurement of floats, anchors and batteries to keep costs in check. Monitoring mechanisms must be set up to address safety concerns such as cable breakage and monsoon access. Successful implementation will not only add 5 GW of clean capacity but also demonstrate a replicable model for land‑constrained regions, helping India meet its climate goals and energy‑security objectives.
