Mundra Plant Roars Back to Life with New PPA Deals
Coastal Gujarat Power Ltd. (CGPL), a Tata Power subsidiary, has signed new power purchase agreements (PPAs) with Gujarat Urja Vikas Nigam Ltd. (GUVNL), clearing the way for its 4,000 MW Mundra Ultra Mega Power Project (UMPP) to restart. The plant had been shut down since July 2, 2025, over disputes about passing on rising imported coal costs. This agreement ends the dispute and allows the plant to resume supplying power to Gujarat, Maharashtra, Rajasthan, Punjab, and Haryana. Following the news on March 20, 2026, Tata Power shares rose about 4-5%, nearing 52-week highs on higher-than-average trading volume. This restart is expected to significantly boost Tata Power's profits. Brokerage estimates suggest the Gujarat PPA could add ₹700-₹800 crore annually, with potential to reach ₹1,200-₹1,400 crore if similar deals are struck with other states.
Recovering from Shutdown: Financial Impact and Outlook
The nine-month shutdown of the Mundra UMPP had a major financial impact, costing Tata Power an estimated ₹800 crore to ₹1,000 crore in losses for the first nine months of fiscal year 2026. During the shutdown, CGPL couldn't collect capacity charges while still facing fixed costs, which hurt overall profits. The new PPAs aim to fix this by allowing the pass-through of actual coal costs. This was crucial, as previous terms became unworkable after government compensation rules changed. Management expects the plant to become cash-positive again and eliminate these specific shutdown-related losses. The improved cash flow will also help fund investments in renewable energy, hydro projects, and grid infrastructure.
India's Green Shift and Coal's Role
The Mundra UMPP restarts as India's power sector rapidly shifts towards renewable energy, putting coal-fired plants under greater scrutiny. Global coal and freight costs have increased. While renewables offer cheaper electricity, states still sign thermal power deals at higher rates (₹5.38-₹7.27/kWh) to ensure consistent baseload power. Competitors like NTPC trade at much lower P/E ratios (15.33-23.25), and Adani Power's P/E is also lower (22.5-25.77) than Tata Power's. India's coal power plants are running at lower capacity, with the average PLF dropping to about 55% by FY 2031-32. This trend is expected to push coal power costs up by roughly 25% by FY31-32 compared to FY24-25. This environment forces Tata Power to balance its existing thermal assets with ambitious expansion into renewables, solar rooftops, and EV charging.
Valuation Jitters and Risks Remain
Even with the Mundra PPA agreement, significant risks remain. Tata Power's P/E ratio (31.7-34.52 as of March 2026) is much higher than its peers. This suggests investors expect strong future growth, which might be difficult given the company's focus on both older thermal plants and new green energy projects. The new PPAs still need regulatory approval. Key terms, like pricing and how long the agreements will last, are critical but not yet fully public. Additionally, the financial stability of state-owned power distributors, such as GUVNL, is a lingering concern. Their financial health affects credit risk, potentially increasing borrowing costs and limiting capital in the sector. Tata Power has a history of disputes and financial losses tied to its Mundra UMPP, including past equity erosion and cancelled power deals with Rajasthan distributors. Management has stated the PPA rate follows regulatory directives and matches deals with the Adani group. However, the full financial impact and long-term success of these terms in a changing market are still uncertain.
Analyst View: Cautious Optimism on Growth
Analysts generally hold a positive view, with most rating Tata Power as 'Outperform' or 'Buy'. Average price targets suggest an upside of 17-25% from current trading levels, ranging from ₹400.60 to ₹458.33. Projections forecast around 19.9% annual earnings growth and 10.4% revenue growth over the next three years. However, some analysts remain cautious, keeping a 'Hold' rating due to valuation concerns. Key factors for future stock performance include successfully applying the Mundra PPA model elsewhere and managing grid integration for its renewable energy projects.
