Background

The rapid growth of solar photovoltaic (SPV) technology has become a key driver of the global shift towards low-carbon energy systems. Declining module costs, technological advancements, and stronger climate commitments have accelerated solar adoption worldwide. In recent years, floating solar photovoltaic (FSPV) has emerged as an innovative approach involving the installation of solar panels on reservoirs, lakes, and other water bodies. It provides a sustainable alternative to conventional ground-mounted solar projects by enabling renewable energy expansion while addressing land availability challenges.

Building on this global momentum, India’s growing electricity demand and commitment to achieving its climate goals have increased the need for innovative renewable energy solutions. Although India’s solar power capacity has expanded significantly, the availability of suitable land for large-scale projects remains a challenge. To address this, the Government of India approved the Pradhan Mantri Surya Sarovar Yojana (PM-SSY) in 2026 with a financial outlay of ₹5,070 crore. The scheme aims to develop 5,000 MW of floating solar photovoltaic (FSPV) capacity, integrated with Battery Energy Storage Systems (BESS), to enhance energy security and support India’s transition towards a cleaner and more resilient energy future.

The Union Cabinet approved the Pradhan Mantri Surya Sarovar Yojana (PM-SSY) on 31 July 2026. Under the scheme, floating solar projects will be sanctioned between FY 2026–27 and FY 2030–31, while financial support will continue until FY 2032–33. The scheme is backed by a National Institute of Solar Energy (NISE) assessment, which estimates that India has a floating solar potential of around 102.18 GWp across reservoirs and other suitable inland water bodies. The assessment provides the technical basis for the scheme and highlights India’s significant potential to utilise inland water bodies for large-scale renewable energy generation, improving grid reliability through energy storage, creating employment opportunities, encouraging domestic manufacturing, and supporting India’s renewable energy and climate goals.

Functioning
