Mundra Plant Shutdown Hits Q4 Results

Tata Power's fourth-quarter performance for FY26 was significantly impacted by the temporary closure of its Mundra Ultra Mega Power Plant. This closure, following the expiry of its power purchase agreement with Gujarat, 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, which will remove this issue for the upcoming fiscal year.

Record Annual Profit Achieved Despite Quarterly Dip

Offsetting the quarterly downturn, 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 Energy and Solar Manufacturing Shine

The company's strategic pivot towards clean energy continues to yield 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, benefiting from capacity ramp-ups and improved yields exceeding 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.

Transmission and Distribution Boosted by Network 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. Performance in the Odisha distribution companies showed marked improvement, 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.

Hydropower Partnership Expanded with Bhutan

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 Standing

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 Asian Electric Utilities industry average P/E is considerably lower at 15.9x, suggesting Tata Power 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.

Sector Growth Amid Regulatory 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.

Arbitration Award and Debt Concerns

A major risk facing Tata Power is a significant arbitration award. In August 2025, the Singapore International Arbitration Centre (SIAC) ordered Tata Power to pay Kleros Capital Partners $490.32 million, plus costs and interest. This award stems from disputes over a Russian coal mining partnership. Tata Power is appealing the decision and has not made any provision for the payout, highlighting it as a potential future liability. The company also faces allegations of arbitrator misconduct related to the case. Separately, Tata Power's debt levels have risen considerably. Non-current borrowings increased to ₹61,609 crore from ₹44,130 crore, pushing its debt-to-equity ratio to around 156.2%. MarketsMojo noted a high Debt to EBITDA ratio of 5.06 times and a falling interest coverage ratio as of March 31, 2026. This high debt combined with the unprovided arbitration award presents significant risks to the company's future financial health.

Analyst Views Remain Mixed

Analyst sentiment remains 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. Current average 12-month price targets range from ₹410 to ₹453.75, suggesting limited upside or even downside from recent trading levels. Citi initiated coverage with a 'Buy' rating, citing the transition to renewables and T&D expansion.

Future Outlook Hinges on Key Factors

With the Mundra plant back online and strong momentum in its renewable and distribution segments, Tata Power is positioned for renewed operational growth. However, the resolution of the arbitration matter and the management of its debt levels will be critical determinants of its future financial performance and investor confidence.
