Vikram Solar, NTPC Green, Waaree Lead India's Green IPO Boom; What Retail Investors Must Watch Before Buying?

Green Energy IPO Boom: Renewable energy has become the defining theme of the decade. Hundreds of green power companies are rushing to cash in on the opportunity and make their debut in the Indian stock market through initial public offerings (IPOs). NTPC Green Energy, Waaree Energies, Premier Energies, and others emerged as green energy IPO stars last year.

The rally got an extra boost when Vikram Solar made a strong debut, further charging up investor confidence. But with so many mainboards and SME IPOs hitting the market over the last two years, one big question remains: Has India's green energy IPO market reached its peak? Or is it just the beginning?

"India's green energy IPO cycle is still in its growth phase, not its peak. Non-fossil capacity has crossed a milestone-246.3 GW out of 490 GW as of July 31, 2025, or just over 50% of India's total installed power base. This shift cements renewables at the core of India's power system," noted Harshal Dasani, Business Head INVasset PMS.

He highlighted the crucial role of policy support in boosting sentiment around the sector, and warned that the sector is prone to geopolitical headwinds, trade volatility and supply-side bottlenecks.

"Risks lie in the cyclicality of global supply chains. Module prices, which collapsed in 2024, are showing renewed volatility in 2025, and trade actions in the US and EU could create regional gluts or bottlenecks. But with demand visibility, financing costs trending lower, and state backing, the IPO boom still looks like an unfolding story rather than a topping-out event," Dasani added.

India's Green Energy IPO Market

The Nifty Energy Index has declined by around 17.26% in one year. NTPC Green Energy's share price value has declined by around 19.1% in 2025 so far. Premier Energies shares are trading above their IPO price, but the stock value has fallen by 20.88% year to date (YTD). Waaree Energies' stock has outperformed its peers, and its valuation has surged around 27% year to date (YTD).

Reviewing the green energy IPOs' performance in FY26 so far, Dasani noted, "Vikram Solar's August 2025 IPO was the standout-its ₹315-₹332 issue price was subscribed 54.6× overall and the stock listed with a muted 2-3% premium, closing ~7-8% higher on debut with an intraday high of ~14%."

Green Energy IPO Boom: Key Factors Investors Must Check Before Investing

Given the strong pipeline of upcoming IPOs in this segment, investors should proceed with caution. Assessing factors such as fundamental growth, order book strength, and project execution can help in determining fair valuations.

"Investors should keep track of execution and orderbook, PPA visibility, policy and fiscal support and movement in raw material prices (cells/modules) for better margin visibility. Localisation of cells and modules will be a major factor, along with access to cheap capital for these companies," explained Vaqarjaved Khan, Senior Fundamental Analyst, Angel One.

"Assess EBITDA per MW based on normalised module prices, not temporary troughs. Check for integration into wafers, cells, and modules to defend margins, and scrutinise order-book coverage, receivable cycles from DISCOMs, and debt sustainability. Stress-test projects against aggressive tariffs under the government's annual 50 GW tender program," stated Harshal Dasani.

IPO Red Flags

Investors must also look for signs of caution before investing in an IPO. IPOs dominated by offer for sale proceeds with limited fresh capex, poor cash conversion, and reliance on a single export geography can be a cause of concern, highlights Harshal Dasani.

Valuations trading significantly above global peers, without a comparable return ratio, are another clear sign of market froth. "If an IPO's valuation case assumes flawless execution and benign global policy, caution is warranted," he added.

Upcoming IPOs In Green Energy Segment

Recently, Prozeal Green Energy received approval from the Securities and Exchange Board of India for IPO. Other than Prozeal Energy IPO, Juniper Green Energy, Continuum Green Energy (Apr 2025), Saatvik Green Energy, GK Energy, and PMEA Solar Tech, Rayzon Solar and Solarworld Energy Solutions can draw investors' interest with their IPOs.
