In 30 seconds

The market expects Tata Power to carry on much as it has.

At today’s share price, buyers are assuming Tata Power grows about 7% a year, forever. Over the last ten years it actually grew about 9% a year. The two are close, so the share price does not need the business to improve or to stumble. It needs it to keep doing roughly what it already does.

  • How it is valued: Discounted cash flow.
  • What the price assumes: 7% growth, against 9% the model takes from its own record.
  • Ten-year record: Between FY2018 and FY2026, Tata Power's revenue went from ₹29,331 crore to ₹62,429 crore — it compounded at about 10% a year over 8 years.
  • Biggest swing factor: Renewable capacity. Main risk: Execution.

01Generation, renewables and distribution

Tata Power, part of the Tata group, built India's first large hydro plants in the early 1900s. It generates power from coal, hydro and a fast-growing renewable portfolio, and distributes electricity in Mumbai, north Delhi and Odisha.

Through its renewables arm it develops solar and wind farms, makes solar cells and modules, installs rooftop solar and runs EV charging. Its Mundra coal plant has long been a drag on returns.

02What the market is assuming

Work backwards from today's share price and you can see what buyers are quietly taking for granted. Here is the growth that price implies for Tata Power, next to what the model assumes from the company's own record.

The further apart these two numbers are, the bigger the bet a buyer at today's price is making.

03Tata Power's record, in plain numbers

Between FY2018 and FY2026, Tata Power's revenue went from ₹29,331 crore to ₹62,429 crore — it compounded at about 10% a year over 8 years. Net profit grew from ₹2,679 crore to ₹5,118 crore, about 8% a year — roughly in step with revenue. In FY2026 it kept 8.2% of revenue as net profit — against a low of 4.4% in FY2021 and a high of 9.1% in FY2018. Revenue slipped 4.7% in the latest year, well behind its own long-run pace. FY2019 is missing from the filed series used here, so that year is left out rather than estimated.
