CLSA flags a weak FY26 for Tata Power, citing the end of Mundra's compensatory tariff and heavy renewables capex. The stock's next move hinges on whether the earnings trough is already priced in.
CLSA has flagged the fiscal year starting April 2025 as a weak one for Tata Power. The brokerage’s note points to a convergence of headwinds that are likely to depress earnings just as the company ramps up its renewable energy transformation. For traders tracking the stock, the call raises a direct question: is the FY26 trough already reflected in the price, or does the market still have downgrades to absorb?
The core of CLSA’s caution rests on three specific pressure points. First, the compensatory tariff for the Mundra Ultra Mega Power Plant is set to expire. That tariff was a temporary regulatory relief that shored up cash flows at a plant plagued by low utilisation and high imported coal costs. Without it, Mundra’s contribution to standalone generation profits will shrink materially. Second, merchant power prices are softening as new thermal capacity comes online, squeezing margins for Tata Power’s coal-based fleet. Third, the company’s heavy renewables capex cycle is adding interest and depreciation costs before the new projects begin to generate meaningful returns.
These factors are not new, however the simultaneous impact in a single fiscal year creates a trough that CLSA believes the Street may be underestimating. The brokerage’s view is that consensus earnings estimates for FY26 still embed too much optimism about the pace of recovery in the generation business and the timeline for renewable project commissioning.
The Mundra plant has been a persistent drag on Tata Power’s returns. The compensatory tariff, approved after years of litigation, allowed the plant to recover some of its higher fuel costs. With that mechanism ending, the plant reverts to a standard tariff structure that may not cover its full cost of generation. CLSA’s analysis likely models a sharp drop in the plant’s earnings before interest and tax, turning it from a modest contributor to a potential loss-maker in FY26.
This regulatory reset is not a surprise, yet its timing coincides with a period when Tata Power’s other thermal assets are also facing margin pressure. The combination leaves the standalone generation segment exposed, and the company’s consolidated net debt leaves limited room for earnings shocks without affecting credit metrics.
Tata Power is investing aggressively in solar, wind, and transmission infrastructure. The long-term logic is sound: India’s energy transition demands massive capacity additions, and the company is positioning itself as a leading integrated player. The near-term financial impact, however, is a drag on reported profits. Interest costs are rising as the company draws down debt to fund construction, and new projects add depreciation charges long before they reach commercial operation.
CLSA’s note appears to treat FY26 as the year when this mismatch is most acute. Several large renewable projects are expected to be commissioned only toward the end of the fiscal year or in FY27, meaning their earnings contribution will be minimal. The brokerage may see FY27 as the inflection point, with FY26 serving as a clearing event that resets expectations.
Tata Power’s shares have already corrected from their highs, reflecting some of the known headwinds. The critical decision for investors is whether the FY26 earnings trough is fully priced in. If CLSA is right that consensus numbers are still too high, further estimate cuts could trigger another leg down. If, however, the market has already discounted the weak year and is looking ahead to the renewable pipeline, the stock could find support near its book value.
The next concrete catalyst is the Q4 FY25 results and management’s commentary on FY26 guidance. Any signal on asset monetisation, such as a stake sale in the renewables platform, could alter the debt and earnings trajectory. For now, the CLSA call frames FY26 as a year of transition that will test the patience of shareholders waiting for the green energy pivot to pay off.
