Summary
As India accelerates its clean energy transition, here are five undervalued renewable energy stocks for your watchlist.
Renewable energy has been an investment theme for some time now — but what’s different today is that the numbers are no longer just promising, they’re proving themselves.
India’s clean energy transition has moved past the “potential” stage and into the delivery stage, and that changes the investment conversation. New and renewable energy and consumer affairs minister Pralhad Joshi has said India now ranks third globally in renewable energy installed capacity, according to the Renewable Energy Statistics 2026, moving ahead of Brazil in the process.
The minister highlighted several landmark achievements. In July 2025, India hit its highest-ever renewable energy share in electricity generation, with renewables meeting 51.5% of the country’s total electricity demand of 203 GW — a historic milestone.
As of 31 March 2026, a total of 283.46 GW of capacity from non-fossil fuel sources has been installed across the country.
Further, the non-fossil capacity addition in 2025–26 stood at 55.29 GW — the highest single-year increase ever recorded, nearly doubling the previous record of 29.5 GW set in 2024–25.
For a while, renewable stocks were priced on hope. Now they’re being tested against real capacity additions, real grid integration, and real policy execution.
With that in mind, here are five undervalued renewable energy stocks to watch. Some of the companies that we have chosen also generate power from other sources.

Conclusion
India’s renewable energy sector is entering a phase of accelerated growth, supported by strong policy backing and massive capital investments.
The country is expected to invest more than US$360 bn in renewable energy and related infrastructure by 2030, with an estimated US$190–215 bn required to achieve its target of 500 GW of renewable energy capacity.
At the COP26 Summit in Glasgow, Prime Minister Narendra Modi pledged to expand India’s renewable energy capacity to 500 GW and meet 50% of the country’s energy requirements through renewable sources by 2030.
As the nation moves closer to these goals, companies across the renewable energy value chain—from power generation and solar manufacturing to EPC services and energy storage—are likely to benefit from rising demand and increased investments.
Investors should evaluate the company’s fundamentals, corporate governance, and valuations of the stock as key factors when conducting due diligence before making investment decisions.
