Inox Clean Energy IPO: DRHP, ₹10,000 Cr Size & Financials
Inox Clean Energy, the renewable-energy arm of the INOXGFL group, has filed its draft red herring prospectus (DRHP) with SEBI for an initial public offering worth up to ₹10,000 crore (about $1.04 billion), making it one of the largest private-sector renewable-energy IPO proposals in India. Draft papers were filed on Tuesday, 29 September 2026, after the company earlier shelved a confidential filing it had made last year.
The filing comes as India's primary market sees a revival after a slow start to 2026, with several green-energy companies — Clean Max and Juniper Green Energy have already listed this year, while Brookfield-backed Avaada Electro, Sembcorp's India unit and SAEL Industries are preparing IPOs — lining up to tap investor appetite for the clean-energy buildout. Here is a deep-dive into what the DRHP reveals.

| Issue type | Mainboard IPO (book-built) |
| Issue size | Up to ₹10,000 crore (~$1.04 billion) |
| Fresh issue | Up to ₹8,000 crore |
| Offer for sale (OFS) | Up to ₹2,000 crore |
| OFS selling shareholder | Devansh Jain, top shareholder and non-executive director |

The company plans to use about ₹6,000 crore of the net fresh-issue proceeds to repay borrowings — a balance-sheet reset that matters in a capital-intensive business where new projects are typically funded with a mix of equity and loans. Paying down debt can lower interest costs and improve the debt-service coverage ratios banks watch when financing project developers.
About Inox Clean Energy: What the Company Does
Inox Clean Energy is part of the INOXGFL conglomerate, which mainly focuses on renewable energy and chemicals and has three listed companies in India: Gujarat Fluorochemicals, Inox Wind and Inox Green Energy Services.
The company runs two related businesses:
- Renewable power generation — building and operating solar and wind power plants in India and Africa. In India the independent power producer (IPP) business is run through Inox Neo Energies, while African operations are conducted through SkyPower Services MENA, a venture with strategic partner Arctic International.
- Solar manufacturing — producing solar photovoltaic (PV) modules and cells. In India this is carried out through Inox Solar, and the US business operates through Inox Solar Americas LLC, a wholly owned subsidiary of Amura Renewables.
Portfolio snapshot
| Segment | Detail |
|---|---|
| Total renewable portfolio | 9.29 GW across development stages |
| Operational capacity | 2.37 GW |
| Under construction | ~0.80 GW |
| Pipeline capacity | 2.99 GW |
| Future capacity | 3.13 GW |
| Solar cell manufacturing (operational, Aug 2026) | 6.00 GW across India and the US |
| Solar module manufacturing (under construction) | 5.00 GW in Odisha |
| Solar cell manufacturing (under construction) | ~8.00 GW across India and the US |
The company expanded its power generation and manufacturing businesses rapidly over the past year and a half, both organically and through an aggressive acquisition strategy in India and overseas.
Inox Clean Energy Financials
The DRHP shows a sharp improvement in profitability in FY26 (financial year ended March 2026), albeit on a modest base as the enlarged portfolio is still being integrated:
| Particular | FY25 | FY26 |
|---|---|---|
| Revenue from operations | ₹47.2 crore | ₹178.1 crore |
| Profit (PAT) | ₹1.5 crore | ₹30.9 crore |
Revenue grew nearly 3.8x year-on-year and profit turned meaningfully positive as operating assets and manufacturing capacity came on stream. Investors will want to watch the full financial statements, debt position and cash flows in the DRHP to judge how much of the growth is organic versus acquired, and how the ₹6,000 crore debt repayment changes the leverage profile.
Competition and Sector Context
Inox Clean Energy competes with established power producers such as Adani Green Energy, NTPC Green Energy and ACME Solar, as well as solar equipment makers Waaree Energies and Premier Energies. The filing bets on India's drive to expand non-fossil-fuel power capacity to 500 gigawatts by 2030, which underpins the broader renewable-investment cycle.
The IPO would arrive at a time when India's primary market remains highly active. Mainboard IPOs raised about ₹73,674 crore between January and August 2026, according to PRIME Database data cited by Outlook Business — a ₹10,000 crore Inox issue would be equivalent to roughly 13.6% of that total, making it a meaningful test of appetite for another capital-intensive renewable platform.
Inox Clean Energy IPO: Review — Strengths and Risks to Watch
Strengths
- Scale and integrated model: 9.29 GW renewable portfolio plus solar manufacturing across India and the US gives it both generation and equipment legs — a hedge against supply-chain volatility.
- Strong group backing: The INOXGFL pedigree brings operating experience in renewables and access to capital markets; three group companies are already listed.
- Balance-sheet reset: Earmarking ₹6,000 crore for debt repayment directly addresses the leverage concern that typically weighs on renewable developers' valuations.
- Sector tailwinds: India's 500 GW non-fossil target by 2030 supports long-term demand, and listed clean-energy peers have attracted strong investor interest in 2026.
Risks
- Acquisition-led growth: Much of the recent expansion came through an aggressive M&A spree; integration and execution risk is the key variable investors will price.
- Thin reported base: FY26 revenue of ₹178.1 crore and PAT of ₹30.9 crore are small relative to the proposed ₹10,000 crore issue — the eventual valuation will need to be justified by the enlarged portfolio and forward earnings.
- Competitive and crowded field: With Avaada Electro, Sembcorp's India unit and SAEL Industries also preparing IPOs, and listed peers like Adani Green and NTPC Green, pricing will be compared against a wide set of alternatives.
- Policy and tariff risk: Like all IPPs, returns depend on power purchase agreements, tariff realisations and regulatory support for renewables.
What Happens Next
With the DRHP now filed, SEBI will review the draft papers — the regulatory process typically takes a few months before a red herring prospectus is filed and the price band and dates are announced. Key things to track:
- SEBI's observations/approval on the DRHP.
- The final issue structure — whether the ₹8,000 crore fresh issue and ₹2,000 crore OFS change.
- The price band and the implied valuation once announced.
- Anchor investor participation and listing plans.
Conclusion
The Inox Clean Energy IPO is one of the most significant DRHP filings of 2026 — a ₹10,000 crore bet on India's renewable-energy buildout, with ₹6,000 crore earmarked to clean up the balance sheet and an 80:20 fresh-issue-to-OFS mix that is investor-friendly. The real test will come when the price band is announced: investors will weigh the group's execution record and the integrated generation-plus-manufacturing model against a crowded pipeline of clean-energy IPOs. For now, the DRHP puts Inox Clean Energy firmly on every IPO investor's watchlist.
