FY26 revenue stayed stable at Rs 55,583 crores despite lower imported coal tariffs, reflecting steady demand and stable operational performance across its power portfolio.

EBITDA improved strongly, with Q4 continuing EBITDA up 9 percent YoY to Rs 5,573 crores and reported EBITDA rising 27 percent to Rs 6,498 crores, driven by efficiency and asset additions. PAT surged 64 percent YoY to Rs 4,271 crores, while FY26 PAT held steady at Rs 12,971 crores, showing earnings resilience.

Tata Power delivered a strong FY26 performance despite Mundra remaining shut for 9 months. Full-year PAT crossed Rs 5,000 crores for the first time, while EBITDA rose 11 percent YoY to Rs 16,090 crores, supported by growth across generation, transmission, distribution, and renewable businesses.

For the quarter, EBITDA increased 10 percent YoY to Rs 4,216 crores, while PAT rose 8 percent to Rs 1,416 crores. Performance was driven by strong execution across solar manufacturing, rooftop solar, Odisha DISCOM, and utility-scale renewable projects, with improving efficiency and rising contribution from new commissioned assets.

Adani Power outperformed Tata Power in Q4 FY26 on earnings momentum, with PAT rising 64 percent YoY and strong EBITDA growth driven by tariffs and efficiency gains. Tata Power showed steadier, diversified growth with mid-single digit PAT rise, supported by renewables, distribution, and manufacturing despite the Mundra shutdown impact.

Capacity, Sales Volume and Capacity Utilisation

Adani Power delivered strong operational performance in Q4 FY26, with consolidated plant load factor (PLF) at 74 percent and annual PLF at 66.5 percent, reflecting efficient asset utilisation amid demand volatility. Power sales stood at 27.2 billion units in Q4, while full-year sales rose 3.4 percent to 99.1 billion units, supported by higher operating capacity and stable plant availability.

The contracted portfolio remains strong, with 95 percent of 18.15 GW operating capacity tied to long-term and medium-term PPAs, ensuring stable cash flows. Additionally, 13.3 GW of PPAs have been secured for the ongoing 23.7 GW expansion. These contracts provide fixed capacity charges with fuel cost pass-through, improving earnings visibility and supporting better return metrics going forward.

Tata Power reported strong segment-wise performance in FY26, led by solar manufacturing, which delivered PAT of around Rs 857 crore, more than doubling year-on-year. Rooftop solar also performed strongly with PAT of about Rs 499 crore as installations doubled, while Odisha DISCOMs improved profitability to Rs 809 crore, reflecting steady distribution-led earnings growth.

On the operational front, utility-scale renewable projects are progressing with around 5 GW under execution, supporting a strong pipeline. The company’s operational capacity stands at about 16.7 GW with a total pipeline of nearly 26.3 GW, including around 10 GW of long-term additions. Stable demand conditions and diversified energy mix continue to support overall performance visibility.

Adani Power shows a stronger thermal-led operational profile with higher utilisation, reflected in 74 percent PLF in Q4 and 99.1 billion units of annual sales, supported by a large long-term PPA-backed portfolio ensuring stable cash flows. Tata Power, on the other hand, has a more diversified growth model with rising contribution from solar manufacturing, rooftop solar, distribution, and a sizeable renewable pipeline, but comparatively lower near-term volume intensity. Overall, Adani Power leads on scale and utilisation, while Tata Power is stronger on diversification and long-term renewable expansion visibility. 

Business outlook and guidance

Adani Power targets capacity expansion to 23.7 GW by 2032, with 95 percent of operating capacity already tied up under PPAs and 13.3 GW secured for expansion. Key projects include Korba Phase-II nearing FY27 commissioning, while Raipur and Raigarh expansions progress and Mahan Phase-II faces slight delays.

Capex is guided at around Rs 25,000 crores in FY27 and Rs 33,000 crores in FY28, reflecting a strong investment cycle. Demand grew only 0.8 percent in FY26 but is expected to recover in FY27, supported by peak demand reaching 256 GW, improving medium-term earnings visibility.

Tata Power expects strong growth in FY27–FY28 across renewables, distribution, transmission, hydro, and manufacturing segments, supported by integrated operations. Odisha DISCOMs are expected to remain a key earnings driver, while renewable capacity expansion and manufacturing scale-up will support steady EBITDA growth across diversified businesses.

Capex stood at around Rs 13,000 crore in FY26, lower than earlier estimates due to transmission delays and right-of-way issues impacting project execution. However, investment is expected to accelerate to about Rs 25,000 crore in FY27, reflecting stronger execution momentum and focus on regulated and renewable growth areas.

Conclusion: Adani Power Vs Tata Power – Which Power Stock is Better for Long Term?

Adani Power is better positioned as a high-growth thermal play with strong earnings visibility. Its performance is driven by high utilisation, 95 percent PPA-linked capacity, and large-scale expansion plans up to 23.7 GW. Strong capex visibility and tariff-backed cash flows support steady earnings compounding over the medium term.

Tata Power, on the other hand, offers a more balanced and diversified energy transition story. Growth is driven by renewables, distribution, and manufacturing, with a strong 26.3 GW pipeline and rising contribution from clean energy assets. While execution delays have moderated near-term capex, the long-term structural shift towards green energy remains intact.

Overall, Adani Power suits investors seeking strong near-term earnings visibility and thermal-led scale expansion, while Tata Power is better suited for long-term investors looking for diversification and exposure to India’s renewable energy transition.
