Tata Power shares slipped to a fresh 52-week low of ₹333.60 on October 6, 2026, even as the stock was among the actives following the company's floating solar partnership announcement. The stock was trading at ₹342.50 as of 11:23 AM on October 12, rising marginally by 0.1% but still reflecting continued market pressure. The stock has fallen 5.5% over a month, slumped 16% in the past six months, and declined over 10% year-to-date, underperforming the Nifty Next 50 where it is a constituent. The 52-week low of ₹333.60 compares starkly with the 52-week high of ₹464.90 hit in April 2026, with the stock shedding over 11% year-to-date and 12% over the past year. Tata Power shares closed 2.88% lower at ₹335.20 on October 8 on the NSE, reflecting continued market pressure despite the strategic partnership announcement.
Tata Power has officially launched its 300 kWp floating solar pilot project at the Mulshi reservoir in Maharashtra in partnership with Norway-based renewable energy technology company Ocean Sun. The partnership was formalized on the sidelines of the 2nd India–EFTA Prosperity Summit, marking a significant step in integrating advanced global clean energy technologies into India's power infrastructure. According to reports from THEBUSINESSBYTES, the collaboration will undertake a nearly 300 kWp floating solar pilot at Tata Power's Mulshi reservoir in Maharashtra to evaluate the technology's performance, reliability, cost competitiveness and scalability under Indian conditions. The agreement was signed underlining the growing India-Norway and India-European Free Trade Association (EFTA) partnership in technology, innovation and clean energy.
Unlike conventional floating solar systems that use interconnected pontoon structures, Ocean Sun's technology mounts solar photovoltaic (PV) modules on a thin, hydro-elastic membrane that floats directly on the water surface. As reported by THEBUSINESSBYTES, the pilot will compare this technology with conventional floating solar systems on energy generation, capacity utilisation factor (CUF), installation methodology and time, reliability, operations and maintenance (O&M) requirements, capital cost and overall commercial viability. The lightweight design aims to simplify transportation and installation while reducing structural requirements. Additionally, the close proximity of the modules to the water surface may provide a cooling effect, potentially enhancing generation performance compared to traditional setups. This design could simplify transportation and installation while reducing structural requirements.
The Mulshi pilot leverages existing hydro project assets that present a total combined floating solar potential of 750 MW across Tata Power's facilities, positioning the company as an early adopter of land-efficient solutions. According to Tata Power, estimates by the National Institute of Solar Energy put India's floating solar potential at more than 102 GWp. The deployment of floating solar on existing reservoir surfaces avoids the typical land acquisition bottleneck that slows down large-scale Indian utility projects. It also directly positions the company as a key competitor in public utility auctions for mega floating solar installations. The pilot project shows active innovation alongside robust financial execution, with Tata Power executing a record capital expenditure of ₹5,375 crore during Q1 FY27 to scale clean energy infrastructure. Tata Power's total capacity, operational and under construction, stands at over 26 GW.
Tata Power's Q1 FY27 results demonstrate strong financial performance supporting the floating solar initiative. The company recorded a consolidated net profit of ₹1,176 crore, representing a 11% YoY growth from ₹1,060 crore in Q1 FY26. Consolidated operational revenue increased 5.6% YoY to ₹19,051 crore from ₹18,035 crore in the prior-year period. However, consolidated operating EBITDA fell to ₹4,013 crore from ₹4,139 crore in Q1 FY26, with EBITDA margin contracting to 21.06% in the reporting quarter from 22.95% in Q1 FY26. The company approved plans to establish a ₹6,675 crore, 10 GW solar ingot-and-wafer manufacturing facility in Gopalpur, Odisha, as announced in July 2026. The strong capital alignment supports the technological partnership and positions Tata Power for long-term land-efficient solar scaling.
SBI Securities flagged the development as "positive in medium to long term," noting the collaboration's focus on evaluating new-generation floating solar technology under Indian conditions. The stock's current P/E stands at 20.98. Shares of Tata Power Company Ltd closed at ₹344.80 on October 7, down 1.95% from the previous close, according to CNBC TV18. The market reaction reflects investor response to the company's strategic technology partnership and floating solar initiatives. Dr Praveer Sinha, CEO&MD of Tata Power, emphasized the strategic importance of the pilot, stating: "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." The collaboration leverages Tata Power's existing footprint, which includes approximately 17.7 GW of clean and green energy capacity, to test new technologies within an established operational framework.
