Key highlights
- Pilot project capacity of ~300 kWp to be installed at Mulshi reservoir, Maharashtra
- Deployment of Ocean Sun’s patented hydro-elastic membrane-based solar technology
- Partnership aims to address India's estimated 102 GWp floating solar potential
- Agreement signed during the 2nd India-EFTA Prosperity Summit to boost clean energy ties
- Pilot to evaluate energy generation, installation time, and O&M requirements
Innovative Solar Technology At Mulshi Reservoir
Tata Power is collaborating with Ocean Sun to deploy a ~300 kWp floating solar pilot at its Mulshi reservoir in Maharashtra. This initiative departs from conventional floating solar systems that utilize interconnected pontoon structures. Instead, Ocean Sun’s technology mounts solar PV modules on a thin, hydro-elastic membrane that sits directly on the water.
This lightweight design aims to simplify transportation and reduce structural requirements. The pilot project serves as a testbed for Ocean Sun’s proprietary technology, allowing Tata Power to assess performance, reliability, and cost-competitiveness. This development follows a period where the company reported a June 2026 quarter revenue of ₹19,051.26 crore, representing a 5.63% year-on-year increase.
Comparing Membrane-Based To Conventional Solutions
- Lightweight hydro-elastic membranes replace heavy pontoon structures for module mounting
- Direct water contact provides a cooling effect that may enhance PV generation performance
- Simplified logistics and installation processes designed to lower capital expenditure
- Strategic focus on India's 102 GWp floating solar potential as estimated by NISE
- Evaluation of Capacity Utilisation Factor (CUF) against standard ground-mounted solar
- Reduced water evaporation from reservoirs as a secondary environmental co-benefit
Strategic Clean Energy Expansion
The partnership strengthens Tata Power’s extensive renewable energy portfolio, which includes 17.7 GW of clean energy capacity and an under-construction project pipeline of 5.3 GW as of June 30, 2026. This pilot follows other major international ventures, such as the May 2026 agreement with Bhutan’s Druk Green Power Corporation to expand hydropower development to over 5,000 MW. By targeting floating solar, Tata Power seeks to reduce land dependence while scaling its ecosystem.
The company currently maintains a P/E ratio of 28.52, compared to the industry average of 21.69, and continues to pursue its 2045 Net Zero target through diverse technological collaborations across India and EFTA nations.
Management On Accelerating Clean Energy Transition
Our collaboration with Ocean Sun reflects our commitment to bringing advanced global technologies to India and evaluating their potential in real-world conditions. Through this floating solar pilot, we aim to generate valuable operating insights and assess its potential to deliver reliable, scalable and cost-effective clean power solutions.
