Largest Floating Solar Power Plants in India: Top 7 in 2025
Floating solar projects are established on large water bodies to integrate solar panels on the water's surface. These power panels can convert sunlight falling on water to electricity with enhanced efficiency compared to typical rooftop solar systems.
Wattsun Energy India is one company contributing significantly to the growth of solar power generation in the nation. The company offers professional solar installation services to residential and commercial clients for rooftop solar generation. In this blog, we discuss the largest floating solar power plants in India in 2025.
Floating Solar Power Plants in India: What Are Floating Solar Power Plants?
The fundamental working principles of a floating solar panel are the same as those of a traditional solar panel. However, floating solar projects in India operate in challenging aquatic settings and leverage the benefits of water-based environments. The following are some benefits of floating solar power projects in India over land-based solar projects:
• Advanced photovoltaic (PV) cells for enhanced solar radiation absorption
• Energy conversion from absorbed sunlight to direct current (DC) with solar panels optimized for the water environment
• The integrated inverters convert from DC to AC to be compatible with everyday electrical systems and grids.
• Energy distribution through power grids for local use to maximize utility and cut energy loss
• They use underutilized spaces on water bodies and show high performance because of cooler operating conditions.
Floating Solar Power Plants in India: Why is India Investing in Floating Solar Power?
The following are the key reasons for growing investments in floating solar power plants in India:
• Floating solar projects in India generate electricity without using more space on land, for which the nation faces constraints.
• With floating solar panels, less water gets evaporated from reservoirs, helping in water conservation.
• Floating solar is considered significant in achieving India's ambitious targets for renewable energy.
• Government incentives and policies to encourage floating solar project development.
• Technological advancements are making floating solar technology more efficient and cost-effective.

Largest Floating Solar Power Plants in India in 2025: Capacity, Location & Benefits
1. National Thermal Power Corporation (NTPC) Floating Solar Plant at Ramagundam
The NTPC floating solar plant at Ramagundam in Telangana has a nameplate capacity of 100 megawatts (MW). The project's transformer, inverter, and other electrical equipment are placed on floating ferrocement platforms. These platforms are anchored to concrete blocks of dead weight to maximize space use, cut evaporation rate, and enhance power generation efficiency.
2. NTPC Floating Solar Plant Kayamkulam (Floating Solar Power Plant in Kerala)
The National Thermal Power Corporation (NTPC) set up a 92-MW floating solar power project at its Kayamkulam unit in Kerala. This floating solar power plant in Kerala is the second-largest in the nation and second in our list of the largest floating solar power plants in India in 2025: capacity, location & benefits. Presently, the Kerala State Electricity Board (KSEB) is purchasing power from this Kerala solar power plant at around ?3.2 per kWh.
3. Simhadri Floating Solar Plant
The Simhadri thermal station, with a capacity of 25 MW, was commissioned by NTPC at Visakhapatnam in Andhra Pradesh in 2021. This is one of the top floating solar power projects in India, which is capable of powering around 7000 households and preventing an annual CO2 emission of 46,000 tons.
4. Rihand Floating Solar Plant
Rihand Floating Solar Plant in Uttar Pradesh, with a capacity of 150 MW, is also another notable project among the top floating solar power projects in India. Under a power purchase agreement, Uttar Pradesh will buy the power generated from this floating solar power plant in India for 25 years.
5. Omkareshwar Floating Solar Plant
The Omkareshwar floating solar plant, which is to be commissioned in Madhya Pradesh, is expected to be the largest floating solar power plant in the world upon completion. This floating power plant with a capacity of 600 MW is expected to prevent an annual carbon dioxide emission of 12 lakh metric tons.
6. Sagardighi Floating Solar Project
The Sagardighi Floating Solar Project in West Bengal, with a 5 MW capacity, is one of the top floating solar power projects in India. The solar panel installations at Sagardighi should generate power equivalent to the needs of around 1000 homes.
7. Getalsud Dam Floating Solar Project
The Getalsud Dam floating solar power project in Jharkhand, with floating solar panel installations of 100 MW capacity, is the last on our list of the largest floating solar power plants in India in 2025: capacity, location & benefits. This, like other solar power plants in India, is expected to reduce evaporation, preserve land, and improve the efficiency of power production.
Advantages of Floating Solar Power Plants
• Space Efficiency
Floating solar power plants in India capitalize on underutilized water bodies like lakes, reservoirs, and dams. Thus, solar energy is generated without giving up valuable land resources.
• Enhanced Efficiency
Floating solar power plants in India undergo thermoregulation because of the low operational temperature and natural cooling effect of water. This is expected to boost solar panel efficiency by about 15%.
• Albedo Effect
Water bodies have inherent reflective properties because of the albedo effect. The sunlight thus reflected from the surface of water bodies falls on the floating solar panels, resulting in increased efficiency in power generation.
• Water Conservation
Floating solar panel installations occupy large areas of water bodies, creating a shading effect that curbs water evaporation. Further, solar panels prevent the growth of harmful algae by hindering sunlight penetration into water, preserving the water quality.
• Reduced Installation Costs
Floating solar installations avoid the need for land acquisition and extensive preparation of the site. Further, the nearness of existing electrical infrastructure also saves expense on infrastructure for transmission and integration.
• Low Impact on Aquatic Life
Floating solar panels can be designed and positioned to ensure a harmless coexistence with the aquatic ecosystem.
• Supportive Policies
The incentives for the generation of renewable energy along with reduced costs of floating PV systems are other advantages.
• Scalability and Flexibility
Floating solar panels have modular qualities for adjusting and expanding to accommodate different configurations and site dimensions.
Floating Solar Power Plants in India: Closing Thoughts
Floating solar power plants in India use existing water bodies for clean energy production. This makes them a unique solution to land scarcity by conserving valuable land for other needs. Hence, floating solar plants are crucial to India's future in renewable energy generation.
