The Mundra Plant's Impact and Restart
Tata Power's fourth-quarter performance for FY26 was significantly hit by the temporary shutdown of its Mundra Ultra Mega Power Plant. This closure, due to its power purchase agreement with Gujarat expiring, led to a 12.8% year-on-year drop in revenue to ₹14,900 crore and a 4.5% decline in consolidated net profit to ₹996 crore. The thermal and hydro power segment saw its EBITDA plummet, and EBITDA margins contracted to 17.44% from 18.98% in the prior year's quarter. Critically, a new supplemental PPA was secured in March 2026, allowing the plant to resume operations on April 1, 2026, removing this issue for the upcoming year.
Full-Year Resilience in Numbers
Balancing the quarterly dip, Tata Power delivered its highest-ever reported annual profit after tax (PAT) of ₹5,118 crore for the full fiscal year 2026, a 7% increase from FY25. While consolidated net profit attributable to owners dipped slightly to ₹3,747 crore due to the Mundra impact, annual EBITDA surged 11% to ₹16,090 crore on full-year revenues of ₹63,681 crore. Adjusted earnings per share (EPS) for FY26 stood at ₹12.0.
Renewable & Manufacturing Momentum
The company's shift to clean energy is yielding strong results. The renewables business was a standout performer, with PAT before exceptional items soaring 59% year-on-year to ₹1,994 crore. Tata Power added 406 MW of utility-scale renewable capacity in Q4, bringing its total installed renewable capacity to 6.5 GW. The solar cell and module manufacturing segment more than doubled its PAT to ₹857 crore, thanks to increased capacity and yields over 95%. The rooftop solar business also saw remarkable growth, with annual PAT rising 150% to ₹499 crore, fueled by a significant jump in residential revenue.
Distribution and Transmission Gains
The transmission and distribution (T&D) business reported a substantial 49% increase in FY26 PAT to ₹2,978 crore. Tata Power fully commissioned the 1,521 circuit kilometre SEUPPTCL transmission line, adding considerable network capacity. Odisha distribution companies performed much better, with annual PAT jumping 84% to ₹809 crore, supported by an 84% rise in EBITDA. AT&C losses across these discoms declined to 15.5% from 17.5% in FY25, with nearly 2.7 million smart meters installed.
Strategic Hydropower Expansion
Tata Power deepened its regional energy ties by expanding its hydropower partnership with Bhutan's Druk Green Power Corporation. An amended MoU now includes the 404 MW Nyera Amari I & II Hydropower Project, bringing the total identified portfolio to 5,033 MW. This collaboration is seen as critical for enhancing regional energy security and meeting India's peak demand.
Valuation and Market Position
Tata Power's market capitalization hovers around ₹1.34 lakh crore, with a trailing twelve-month P/E ratio fluctuating between 30.97x and 37.53x across various reports. While its P/E ratio is comparable to some peers like Torrent Power (26.88x), it appears expensive against NTPC Ltd. (19.32x) and Power Grid Corporation of India (18.58x). The average P/E for Asian electric utilities is 15.9x, much lower than Tata Power's, suggesting it trades at a premium to the broader sector. Notably, Adani Power's market capitalization has surged to approximately ₹4.24 lakh crore as of May 11, 2026, significantly surpassing Tata Power and its other peers, reflecting a dramatic market re-rating within the sector.
Regulatory and Macro Environment
India's power sector is experiencing robust demand growth, with projections for a 4%-5% increase in FY27. The country's installed power capacity reached over 520 GW by January 2026. Fitch Ratings anticipates a strong surge in renewable generation, particularly solar and wind, by around 15% in FY27. However, the sector's expansion is capital-intensive, with lower interest rates being crucial for financing the energy transition.
The Arbitration Shadow and Debt Burden
A major concern for Tata Power is an unfavorable arbitration award from the Singapore International Arbitration Centre (SIAC). In August 2025, a final order directed Tata Power to pay Kleros Capital Partners $490.32 million, plus costs and interest, stemming from alleged breaches of confidentiality in a Russian coal mining venture. The company is appealing the award but has made no provision for it, indicating a significant potential liability. Allegations of potential arbitrator misconduct have also surfaced, adding to the controversy. Concurrently, the company's financial structure shows increasing leverage. Non-current borrowings rose sharply to ₹61,609 crore from ₹44,130 crore, pushing the debt-to-equity ratio to approximately 156.2%. Analysts at MarketsMojo noted a high Debt to EBITDA ratio of 5.06 and a falling interest coverage ratio as of March 31, 2026, signaling a significant debt burden. This high leverage, combined with the unprovided arbitration award, poses a considerable risk to future profits and financial stability.
Analyst Outlook
Analyst views are mixed. While some institutions recommend an 'Outperform' rating, others, like Jefferies, have maintained an 'Underperform' stance with price targets around ₹300-₹340 in previous periods. Average 12-month price targets range from ₹410 to ₹453.75, suggesting limited upside or even a drop from recent trading prices. Citi initiated coverage with a 'Buy' rating, citing the transition to renewables and T&D expansion.
Future Projections
With the Mundra plant back online and strong momentum in its renewables and distribution segments, Tata Power is set for renewed operational growth. However, resolving the arbitration issue and managing its debt levels will be key to its future financial performance and investor confidence.
