Mundra Plant Restarted
Tata Power has successfully resumed operations at its 4,150 MW Mundra thermal power plant, which had been idled since July 2, 2025. The restart follows the signing of supplementary Power Purchase Agreements (PPAs) with Gujarat Urja Vikas Nigam Ltd. (GUVNL), a deal approved by the Gujarat cabinet. Similar agreements are also being finalized with other key states, including Maharashtra, Rajasthan, Punjab, and Haryana.
This development is expected to reverse substantial financial losses, estimated at ₹1,000 crore during its nine-month closure. The new PPA structure is projected to boost annual earnings by ₹700-₹800 crore from Gujarat alone, potentially reaching ₹1,200-₹1,400 crore if extended to all states. Revised commercial terms, including provisions to pass through coal costs, address the financial strain that caused the plant's suspension.
Coal Power's Role in India's Green Transition
The revival of the Mundra plant occurs as India accelerates its transition to renewable energy. Although India's installed renewable capacity has surged, coal-fired power, especially from imported sources like Mundra, remains vital for baseload supply and energy security. Geopolitical tensions affecting global energy markets also highlight the need for reliable domestic power.
Despite falling solar and wind costs, states are signing thermal PPAs at higher rates (₹5.38-₹7.27/kWh) to ensure constant supply. The Mundra plant's restart signifies a strategic necessity for immediate power needs, rather than an abandonment of thermal assets, even as the long-term energy plan favors green energy. The plant's previous halt was triggered by increased imported coal costs that couldn't be passed on under original agreements, showing the volatility of its fuel sourcing.
Valuation and Investor Scrutiny
Tata Power's valuation draws investor attention. The company's Price-to-Earnings (P/E) ratio, between approximately 30.48 and 32.58 as of March 2026, places it at a premium compared to peers like NTPC (P/E of 15.1x-23.25x) and Adani Power (P/E of 22.5x-27.09x). This premium valuation suggests strong market expectations for future growth.
However, this premium must be assessed against the company's continued reliance on thermal assets and the significant capital needed for its ambitious renewable energy expansion. Analysts are divided, with some maintaining 'Buy' ratings and price targets around ₹443-₹500, while others advise caution.
Structural Risks and Challenges
The main risk for Tata Power lies in the long-term viability and economic sensitivity of its imported coal-fired assets. While new PPAs offer stability, imported coal reliance exposes the company to global price volatility and supply disruptions, worsened by geopolitical instability.
Additionally, substantial investments for its aggressive renewable energy targets—aiming for significant solar and wind capacity growth—present a dual challenge. Successfully integrating these diverse assets, managing grid stability for renewables, and securing similar PPA terms across all states will be crucial. Balancing thermal asset upgrades with massive green energy expansion could strain finances and affect returns if not managed effectively. Past issues, like the withdrawal of the Section 11 provision that compensated for higher input costs, highlight regulatory and market shifts that can affect profitability.
Analyst Outlook
Looking ahead, analysts forecast revenue and earnings growth for Tata Power, projecting annual earnings growth around 20.1% for the next three years. However, successfully replicating the Mundra PPA model across other states is key to achieving these forecasts.
The company's ability to manage costs, navigate regulatory changes, and execute its renewable energy pipeline will determine its valuation trajectory. While the PPA provides immediate financial relief and continuity, the long-term outlook depends on Tata Power's strategic balance between its thermal infrastructure and its commitment to a decarbonized future.
