Top 10 Floating Solar Power Plants of India: 2025 Update

India has more than 18,000 km of canals, 5,000+ reservoirs, and millions of hectares of inland water bodies. Each of those water bodies is also potential solar real estate. Floating photovoltaic (FPV) systems — solar panels mounted on buoyant platforms anchored to the bed of lakes, reservoirs, and industrial ponds — have moved from demonstration projects to gigawatt-scale infrastructure in India over the past five years.

Direct answer. India’s top floating solar power plants in 2025 range from the 600 MW Omkareshwar project in Madhya Pradesh (set to become the world’s largest FPV installation) to operational plants at NTPC Ramagundam (100 MW), NTPC Kayamkulam (92 MW), and NTPC Simhadri (25 MW). Floating solar in India offers 5–15% higher yields than equivalent ground-mount systems due to the water-cooling effect on module temperature, while reducing water evaporation by 20–30%. Engineering complexity — anchoring design, cable routing, pontoon selection, and O&M access — is significantly higher than ground-mount.

This post covers India’s leading FPV installations, the engineering decisions that make or break each project, key cost benchmarks, and the design deliverables that underpin a bankable floating solar project. Whether you are an EPC sizing a 5 MW FPV system on an industrial pond or a developer evaluating a 100 MW reservoir project, the engineering details covered here apply directly to your next brief.

Why India Is Building Floating Solar at Scale

India’s solar sector faces one structural constraint that limits every ground-mount expansion: land. The future of floating solar power plants in India is increasingly tied to how efficiently developers can navigate land-scarce states. The country needs 280 GW of new solar capacity by 2030 under its NDC commitment, but the best-irradiance states (Rajasthan, Andhra Pradesh, Maharashtra) are simultaneously facing land acquisition complexity, ecological sensitivity, and competing agricultural use.

Floating solar addresses the land problem directly. MNRE’s FPV program guidelines estimate that 1% of India’s inland water body area can support approximately 280 GW of floating solar — the full 2030 target without a single square meter of land acquisition.

Beyond land scarcity, FPV has documented performance advantages over ground-mount:

• Water-cooling effect — Module operating temperature drops 2–8°C compared to ground-mounted panels in the same irradiance zone. For every 1°C reduction in cell temperature, silicon PV power output increases by approximately 0.4–0.5% (per module temperature coefficient). Net performance ratio advantage over ground-mount: 5–15% depending on water body depth and surface wind.
• Water conservation — Floating solar panels shade the water surface, reducing evaporation by 20–33% depending on coverage ratio. For irrigation reservoirs in drought-prone states, this water saving is a co-benefit that justifies the FPV premium over ground-mount cost.
• Reduced algae growth — Reduced light penetration under the panel field inhibits algae growth in industrial and agricultural reservoirs — a secondary benefit that reduces water treatment costs for some users.

According to IEA PVPS Task 13, global floating solar capacity exceeded 5 GW in 2024, with Asia — led by China, South Korea, and India — accounting for over 85% of installed capacity. India’s FPV pipeline positions it as the second-largest market for floating solar by 2027.

The 10 Largest Floating Solar Plants in India (2025)

1. Omkareshwar Floating Solar Power Park — Madhya Pradesh (600 MW)

The Omkareshwar project is India’s most ambitious FPV undertaking and will, upon full completion, be the world’s largest floating solar installation. Located on the reservoir of the Omkareshwar Dam in Khandwa district, the project is developed in phases by a consortium including AMP Energy (100 MW), NHDC (100 MW), and SJVN (90 MW), with evacuation infrastructure coordinated by Rewa Ultra Mega Solar Limited (RUMSL).

As of early 2025, approximately 278 MW has been commissioned. Total project cost: ₹330 Cr for Phase 1 infrastructure; the full 600 MW buildout is estimated at ₹3,000+ Cr. Auction bids settled around ₹3.25/kWh — competitive with ground-mount tariffs in the same zone. The reservoir location requires anchoring systems designed for significant seasonal water level variation (10–15 m between monsoon and dry season), which is among the most technically demanding anchoring challenges in Indian FPV.

2. NTPC Ramagundam Floating Solar — Telangana (100 MW)

Commissioned on July 1, 2022 at a total cost of ₹423 Cr, the Ramagundam project was India’s first large-scale utility FPV project at the time of commissioning and remains a benchmark for NTPC’s FPV program. Located on the ash pond adjacent to NTPC’s Ramagundam thermal plant in Peddapalli district, the 100 MW system is divided into 40 blocks of 2.5 MW each, with 11,200 modules per block.

Environmental co-benefits: reduces water evaporation by approximately 32.5 lakh cubic meters annually; avoids approximately 2.1 lakh tonnes of CO₂ emissions per year. The ash pond environment requires special corrosion-resistant pontoon and cable specifications due to the aggressive chemistry of coal ash leachate.

3. NTPC Kayamkulam — Kerala (92 MW)

Built on a 450-acre lake near Choolatheruvu in Alappuzha district, the Kayamkulam project was developed by Tata Power Solar Systems Ltd. and commissioned by July 2022. The plant comprises approximately 3 lakh solar PV panels supplying power to the Kerala State Electricity Board at ₹3.16/kWh.

Annual CO₂ avoidance: approximately 1.73 lakh tonnes. Kerala’s high humidity and salt-laden coastal air create a challenging environment for floating solar — the project’s success has validated pontoon and cable specifications for tropical coastal FPV applications in India.

4. Rihand Dam Floating Solar — Uttar Pradesh (150 MW, under development)

Located on the Rihand Reservoir, this project is being developed by ReNew Solar Power Private Limited (100 MW) and Shapoorji Pallonji Infrastructure Private Limited (50 MW). It will be Uttar Pradesh’s first major floating solar park. Under a 25-year PPA, power will be sold to UP Power Corporation Limited at ₹3.36/unit. The project’s scale on a large reservoir — Rihand is one of India’s largest man-made lakes — requires mooring systems designed for 20–30 m depth variation.

5. NTPC Simhadri — Andhra Pradesh (25 MW)

Commissioned in June 2021, the Simhadri FPV project was India’s largest operational floating solar project at the time of commissioning. Located on the reservoir adjacent to NTPC’s Simhadri Super Thermal Power Station in Visakhapatnam, the 75-acre project uses over 1 lakh solar panels.

The project was developed under the Government of India’s flexibilisation scheme, which allows NTPC to deploy renewable capacity at existing thermal plant sites. Annual water saving: 1,364 million litres. Annual CO₂ avoidance: 46,000 tonnes. The project powers approximately 7,000 homes.

6. NTPC Kawas — Gujarat (56 MW, integrated)

This project combines 23 MW of floating solar on industrial water ponds with 33 MW of adjacent ground-mounted solar within NTPC’s Kawas gas-based power station compound. The floating component uses the station’s cooling water ponds — a creative use of industrial water infrastructure that avoids new land acquisition.

A notable feature: the project uses domestically manufactured PV modules and cells under the Domestic Content Requirement (DCR) clause of the CPSU Scheme. Estimated annual energy yield: 137 million units.

7. NTPC Auraiya — Uttar Pradesh (20 MW)

Located on the reservoir of NTPC’s Auraiya Gas Power Station, this project by L&T Power was commissioned in February 2021. Annual generation approximately 39,000 MWh. The gas station reservoir provides a stable, controlled water environment — closer to an industrial pond than a natural water body — which simplifies anchoring design and reduces the seasonal variation challenge.

8. Mudasarlova Reservoir — Andhra Pradesh (2 MW)

Commissioned in 2018 by the Greater Visakhapatnam Smart City Corporation Limited (GVSCCL), the Mudasarlova plant spans 20 acres and was among the first municipal-scale FPV projects in India. Annual coal equivalent: 1,540 tonnes prevented. Annual CO₂ avoidance: 300 tonnes. While small by current standards, Mudasarlova established the technical baseline for municipal reservoir FPV in India.

9. Chandigarh Floating Solar — Chandigarh (2 MW)

Built by Hartek Solar under contract from the Chandigarh Renewal Energy and Science and Technology Promotion Society (CREST), this project is located at the Water Works in Sector 39 and stands as North India’s largest floating solar project by capacity (within a water treatment context). Annual output: 28 lakh units; annual revenue: approximately ₹1.38 Cr. The project prevents 80,000 tonnes of CO₂ annually and reduces water evaporation by 382 million litres per year.

10. Getalsud Dam — Jharkhand (100 MW, planned)

Located on the Getalsud Dam reservoir near Ranchi, this L&T-backed project is in the planning stage. When operational, it will significantly expand Jharkhand’s renewable energy capacity and serve as a model for FPV deployment in eastern India’s water-rich but less-developed renewable energy states.

FPV Engineering Complexity: What Makes Floating Solar Different from Ground-Mount

Understanding why FPV costs 20–35% more per MW than equivalent ground-mount systems requires understanding the three engineering domains that are categorically different: structural, electrical, and civil.

Engineering Domain	Ground-Mount Baseline	FPV Additional Requirement
Foundation	Driven pile or screw pile in soil	Buoyancy-designed pontoon system; mooring anchors in water body bed
Structural load	Wind + snow (IS 875 Part 3)	Wind + wave action + water level variation + pontoon fatigue
Cable routing	Conduit in cable trench	Floating cable system; UV+water-resistant, flexible routing
Corrosion	Standard galvanized steel	Marine-grade materials for salt water; epoxy-coated for ash ponds
Access	Road access to any row	Boat-based O&M; pontoon access walkways required
Electrical protection	Standard arc-fault and GFDI	Enhanced moisture-ingress protection; IP68+ junction boxes
Anchoring	N/A	Seasonal water level variation analysis; anchor pull-out testing

The FPV Engineering Design Stack: What a Bankable Project Requires

The FPV 6-Layer Design Stack is the sequence of engineering deliverables that any lender-acceptable floating solar project in India requires. Omitting any layer increases the probability of commissioning delays, structural failure, or lender rejection.

FPV Cost Benchmarks vs. Ground-Mount in India (2025)

The FPV premium over ground-mount narrows when land acquisition is included in the ground-mount cost. In land-constrained states or near urban industrial zones where land values exceed ₹30–50 Lakh/acre, floating solar on an adjacent water body can be cost-competitive with or cheaper than a ground-mount alternative on purchased land.

Environmental and Regulatory Approvals for Indian FPV Projects

FPV projects in India encounter a regulatory approval sequence that differs from ground-mount in several important ways. The PVsyst setup guide for floating solar provides a detailed walkthrough of configuring yield simulations with water-surface albedo and temperature correction in PVsyst 7.4.

1. Water body ownership clearance — Most reservoirs and natural water bodies in India are owned by state governments (irrigation departments, water supply boards, or hydropower authorities). A lease or license agreement with the water body owner is a prerequisite before any project development. NTPC’s FPV projects use in-house water bodies at existing thermal plants, which simplifies this step.

2. Ministry of Environment Forest and Climate Change (MoEF&CC) — Projects on ecologically sensitive water bodies or natural water bodies above 25 MW typically require Environmental Clearance from the State Environment Impact Assessment Authority (SEIAA). Industrial pond projects and ash pond projects have a simplified process.

3. CEA grid connectivity — Projects above 1 MW connecting to the state transmission system require a grid connectivity study and approval under CEA Connectivity Regulations 2019. SERC open access approval is needed before power offtake begins.

4. CEIG approval — State Chief Electrical Inspector to Government approval is mandatory before synchronization. The drawing package (HT SLD, protection relay settings, earthing layout) must meet state CEIG format requirements.

According to Bridge to India’s India Solar Market Outlook 2025, floating solar tariffs in India’s most recent auctions have dropped to ₹3.15–3.45/kWh. The IRENA Renewable Power Generation Cost report 2022 documented the global FPV LCOE decline trajectory that is driving this tariff compression in Indian auctions. — within 10–15% of ground-mount rates — signaling that the technology premium is rapidly narrowing as installation experience grows.

FAQ

What is the typical cost per MW for floating solar in India?

Floating solar costs in India range from ₹4.5 Cr to ₹5.5 Cr per MW (installed) as of 2025, compared to ₹3.2–4.2 Cr per MW for equivalent ground-mount projects. The premium reflects the higher cost of pontoon systems, marine-grade materials, floating cable systems, mooring anchors, and O&M access infrastructure. For large projects above 50 MW, economies of scale and standardized pontoon procurement reduce the per-MW cost. For small industrial pond projects below 5 MW, per-MW costs can reach ₹6 Cr due to fixed design and mobilization costs spread over a smaller base.

How does floating solar improve energy yield compared to ground-mount?

The primary performance advantage is the water-cooling effect on PV module operating temperature. Ground-mounted modules in Indian conditions operate at 50–65°C in summer months; floating modules on well-ventilated water bodies operate at 42–55°C due to evaporative cooling from the water surface. Since silicon PV output decreases approximately 0.4–0.5% per degree Celsius above 25°C STC, a 10°C temperature reduction improves output by 4–5% relative. Combined with slightly higher water-surface albedo contributing to bifacial module rear-side gain, total FPV yield premium over equivalent ground-mount typically ranges from 5–15%.

What water bodies are suitable for floating solar in India?

Suitable water bodies include: irrigation reservoirs, hydropower reservoirs (with water authority approval), industrial cooling water ponds, coal ash ponds, treated wastewater lagoons, and aquaculture ponds (agri-voltaic FPV). Natural rivers, tidal water bodies, and ecologically sensitive wetlands face significant regulatory constraints and are generally not suitable for commercial FPV. The key feasibility criteria are: minimum water depth of 1.5 m at the lowest seasonal level, maximum seasonal water level variation below 20 m, and proximity to a grid connection point.

What is the lifespan of a floating solar system?

FPV system components have different design lives. PV modules are warranted for 25 years (same as ground-mount). HDPE pontoon systems are typically warranted for 20–25 years with UV-stabilized materials. Mooring cables and anchors are designed for 25-year life with periodic inspection and replacement of high-wear components. Floating cable systems have 20-year design lives in freshwater environments; aggressive chemistry (ash ponds, brackish water) reduces cable life to 12–15 years without enhanced insulation specifications. Total system life is typically 25 years with targeted component replacements.

Do floating solar projects in India require environmental clearance?

Projects above 25 MW on natural water bodies typically require Environmental Clearance from the State Environment Impact Assessment Authority under the EIA Notification 2006. Industrial pond projects (coal ash ponds, cooling water ponds) may be covered under the existing environmental clearance for the host facility. Projects below 25 MW on non-ecologically sensitive water bodies may be exempt from formal EC but require a prior notice to the State Pollution Control Board. Consult the latest MoEF&CC guidelines and the applicable state regulations before initiating site preparation.
