INOX Clean Energy, the renewable power arm of the InoxGFL Group, is back in the IPO conversation. According to media reports dated 25 September 2026, the company is preparing to file a fresh draft red herring prospectus (DRHP) with SEBI for an IPO of around ₹10,000 crore. This would be a larger, revised attempt after two earlier confidential filings did not go through.
Before going further, one point matters most: as of 26 September 2026, this offering is not yet a live, publicly documented IPO. There is no confirmed price band, no open or close date, no allotment schedule, and no grey market premium (GMP) worth quoting. Much of what is circulating comes from news reports, not from an official SEBI document. We have flagged what is confirmed, what is merely reported, and what is genuinely unknown.
What is confirmed
A few things are established from credible reporting and the company's own public positioning:
- The business. INOX Clean Energy develops and operates wind, solar and hybrid renewable projects, primarily through its subsidiary Inox Neo Energies, while Inox Solar manufactures solar modules and cells in India and the US.
- Parentage. It is part of the InoxGFL Group, a large industrial conglomerate with interests in chemicals, fluoropolymers and energy. The renewable and specialty chemicals businesses were separated from other Inox Group entities as part of a 2021 family settlement.
- Ownership. The company is reported to be roughly 95% promoter-owned, led by the Vivek Jain-led INOXGFL Group, with Devansh Jain as executive director.
- Book-running lead managers. The earlier filing named JM Financial, Motilal Oswal, Nuvama, IIFL Securities and ICICI Securities as merchant bankers.
- Filing history. A confidential DRHP was submitted around July 2025 for a reported ₹6,000–₹10,000 crore raise. An earlier confidential filing was withdrawn before that, and the July filing was also withdrawn around December 2025.
What is being reported (not yet official)
Several widely cited figures come from market reports rather than a public offer document. Treat them as indicative until the DRHP is actually filed and made available.
- Issue size: approximately ₹10,000 crore, revised upward from the earlier ₹6,000 crore intent.
- Valuation: nearly ₹1 lakh crore, described as pre-money after a January 2026 equity round.
- Stake dilution: roughly 10%.
- Structure: a mix of fresh issue and an offer for sale (OFS) by existing shareholders, with the exact split not disclosed.
- Pre-IPO funding: a reported ₹3,100 crore raised in January 2026 from investors including CalPERS, SUN Group Global and Authum Investments.
- Timing: reports suggest a DRHP filing by end-September or early October 2026.
- Listing: expected on NSE and BSE, which is standard for an issue of this size.
A fresh issue means the company raises new capital that goes onto its balance sheet, typically for growth or debt reduction. An OFS means existing shareholders sell part of their holding, and that money goes to them rather than the company. The balance between the two matters for how much of your money actually funds the business.
What is still unknown
This is the part retail investors should pay closest attention to. As of today, the following are not disclosed:
- Price band and lot size
- Confirmed final issue size
- Open, close, allotment and listing dates
- Exact fresh issue versus OFS breakup
- Anchor investor details
- Subscription data (the offer is not live)
- Grey market premium
Anyone quoting a GMP or a listing gain for INOX Clean Energy right now is guessing. There is no legitimate basis for those numbers until the DRHP is public and the price band is announced. If you want to understand why GMP figures should be treated with caution even for live IPOs, our explainer on what IPO GMP is and how it works is a useful starting point.
The scale story
The reason this IPO is drawing attention is size and ambition. INOX Clean Energy's independent power arm is reported to operate around 5 GW of renewable capacity, with another 11 GW under development. The group has been aggressive on acquisitions, its largest being the reported ₹6,000 crore purchase of Vena Energy India, which added operational capacity, solar and wind projects and battery storage assets.
The company has publicly targeted around 10 GW of installed renewable power and 11 GW of integrated solar manufacturing by FY28, backed by a stated capex plan of roughly ₹1 lakh crore across the IPP business, solar equipment manufacturing and energy storage. If the ₹10,000 crore figure holds, this could rank among the largest private renewable energy IPOs in India.
It would also arrive during a broader wave. Reports suggest more than a dozen Indian renewable companies are queuing with IPO plans, and INOX would join listed peers such as Adani Green and ReNew in the public renewable space.
Risks worth thinking about
A large, fast-growing story carries a matching set of risks. Consider these when the actual numbers arrive:
- Execution and integration risk. Around 10 acquisitions reported over the past year is a rapid pace. Integrating acquired assets and delivering on an ₹1 lakh crore capex plan is operationally demanding.
- Valuation. A ₹1 lakh crore valuation on a company that raises capital heavily and carries acquisition-linked debt needs to be examined carefully against earnings, cash flows and installed-versus-pipeline capacity once the RHP is out.
- Debt. Reports indicate proceeds may be used partly for debt reduction. The scale of borrowing and interest cost will be central to any assessment.
- Sector sentiment. Renewable energy valuations move with policy, interest rates and global capital flows. A large issue can be exposed if sentiment shifts before listing.
- Prior withdrawals. Two earlier filings did not proceed. That is not automatically negative, but it is a reason to read the eventual DRHP closely rather than the headline.
When the offer document does land, learning how to read a DRHP will help you separate the marketing narrative from the financial reality. For a broader view of where this fits, our upcoming IPOs 2026 list tracks large issues in the pipeline.
What to do next
There is no application to make and no price to evaluate yet. The practical step is patience. Wait for the DRHP to be filed and published, then look at the fresh-issue-versus-OFS split, the use of proceeds, the debt position, the operational versus pipeline capacity, and how the valuation compares with listed renewable peers. Only after the price band is announced does discussion of subscription demand or GMP become meaningful.
FAQ
When is the INOX Clean Energy IPO date?
Not yet confirmed. Reports as of 25 September 2026 suggest the company is preparing to file a DRHP for around ₹10,000 crore, with a filing expected by late September or early October 2026. Open, close and listing dates are not announced and depend on SEBI's review after the DRHP is filed.
What is the price band and lot size?
Not disclosed. A price band is set only closer to the offer opening, after the DRHP process. Any price band circulating now would be unverified.
Is there a GMP for INOX Clean Energy?
No meaningful GMP exists at this stage. The IPO is not live and no price band has been announced, so any grey market premium figure would be speculation.
How big is the IPO expected to be?
Reports put the revised size at around ₹10,000 crore at a valuation near ₹1 lakh crore, with roughly 10% stake dilution. These are reported figures and are not yet confirmed in an official SEBI document.
Which exchanges will it list on?
Reports indicate an expected listing on NSE and BSE, which is standard for large mainboard offerings, but this is not yet formally confirmed.
