India Tests Norway's Floating Solar Tech at Mulshi Dam

India just took a major step toward turning its lakes and reservoirs into clean energy powerhouses.

Tata Power has partnered with Norway's Ocean Sun to test a groundbreaking floating solar system at the Mulshi reservoir in Maharashtra. The 300 kWp pilot project will determine whether this technology can help India tap into more than 102 gigawatts of floating solar potential sitting on water bodies across the nation.

Traditional floating solar panels sit on rigid pontoon structures that can be bulky and expensive to install. Ocean Sun's approach is completely different.

Their system uses a thin, flexible membrane that floats directly on the water surface, holding solar panels just inches above the waves. The design requires less structural support, making it easier to transport and install. The water below keeps the panels cooler, which can actually boost their power output.

Over the coming months, Tata Power will measure everything from energy generation to installation time to maintenance costs. They want to know if this technology can deliver reliable, affordable clean power at scale across Indian conditions.

The timing couldn't be better. India is racing to expand its renewable energy capacity, but finding land for massive solar farms remains a challenge. Floating solar offers a solution that doesn't compete with agriculture or development.

"Innovation is central to accelerating India's clean energy transition," said Dr. Praveer Sinha, CEO of Tata Power. The company already operates or is building more than 26 gigawatts of capacity, with nearly 18 gigawatts coming from clean sources.

The Ripple Effect

This pilot could change how India thinks about renewable energy deployment. Thousands of reservoirs, irrigation canals, and water treatment facilities could become dual-purpose infrastructure generating clean electricity while continuing their primary functions.

Floating solar also reduces water evaporation from reservoirs, a crucial benefit in drought-prone regions. Every panel floating on the surface is shade that keeps precious water from disappearing into the air.

The collaboration agreement was signed during the India-EFTA Prosperity Summit, strengthening ties between India and European nations on clean technology. Norway's maritime engineering expertise meets India's massive renewable energy ambitions and local execution capabilities.

If the Mulshi pilot succeeds, it could open the door for floating solar installations across India's 102 gigawatt potential, enough clean energy to power tens of millions of homes without using a single acre of land.
