Inox Clean Energy plans a significant reboot to its public listing, aiming for a Rs 10,000 crore IPO backed by rapid acquisitions, manufacturing expansion, and private capital, marking a major milestone in India’s renewable energy sector.
Inox Clean Energy is preparing a far larger return to the equity market than the one it abandoned last year, with the INOXGFL Group company now working towards a roughly Rs 10,000 crore initial public offering after pulling a smaller plan in December 2025. People familiar with the current discussions told Moneycontrol that draft papers could reach the Securities and Exchange Board of India by late September 2026 or early October, with the company seeking a valuation of about Rs 1 lakh crore.
That would mark a sharp escalation from the confidential filing made in July 2025, when Mint reported that Inox Clean had been aiming to raise around Rs 6,000 crore at a market value of roughly Rs 50,000 crore. Bloomberg had already reported in April this year that the group had revived a flotation that could raise as much as $1 billion, well before the company’s most transformative acquisition of 2026 was announced. By June, Devansh Jain, executive director of INOXGFL Group, told the Financial Express: “We continue to evaluate the IPO plans positively and are targeting the public markets in FY27, subject to market conditions and regulatory approvals.”
The centrepiece of the expansion case is Vena Energy India. When the deal was announced in June, the Economic Times and Mercom India said the platform being acquired comprised 1.2 GW of operating renewable assets, 1.8 GW of projects nearing commissioning and another 3 GW in development, alongside long-term offtake arrangements with the Solar Energy Corporation of India, Gujarat Urja Vikas Nigam, commercial and industrial customers and state distribution companies. Those reports said the purchase, valued at about Rs 6,000 crore, would lift Inox Clean’s operating and near-operating portfolio to around 4 GW, while taking its overall development pipeline beyond 12 GW and adding 2.5 GWh of battery storage capacity.
That transaction did not arrive in isolation. Mercom India described the Vena purchase as the company’s 10th strategic acquisition in 10 months, following a run of dealmaking that has included the purchase of Macquarie-backed Vibrant Energy, SHV Energy-owned SunSource Energy’s operating solar assets, SkyPower Solar India and Evergreen’s hybrid portfolio. The Economic Times said Vibrant’s portfolio totalled 1,337 MW, while Inox Clean’s January statement on the SunSource deal said about 250 MW of operational solar projects had already been acquired, with another roughly 50 MW pending approvals. Those SunSource assets are spread across 13 states and supply power under long-term agreements to customers including Britannia Industries, Jubilant Foodworks, Hitachi Energy and Max Healthcare.
The company has been building out manufacturing alongside generation. The Economic Times and Mercom India both reported that Inox Clean’s solar module capacity stands at about 6 GW, split evenly between India and the US. They added that a 4.8 GW solar cell plant in Dhenkanal, Odisha, and a 3 GW US facility are expected by the end of 2026. Mercom India also said the group had set internal targets of 10 GW of installed renewable independent power producer capacity and 11 GW of integrated solar manufacturing capacity by FY2028, underscoring that this is being pitched to investors as an integrated clean-energy platform rather than a pure project developer.
The contrast with the business that first approached the market last year is stark. Mint, citing a CareEdge report in July 2025, said Inox Clean then had 157 MW of operational capacity, 400 MW under construction and a project pipeline of just over 2.2 GW. The same report said about Rs 6,500 crore of capital expenditure would be required to complete renewable and manufacturing capacity already under way. Against that backdrop, the jump from a proposed Rs 6,000 crore issue at a Rs 50,000 crore valuation to a mooted Rs 10,000 crore issue at roughly twice that valuation reflects how aggressively the group has used acquisitions to reshape its scale before trying the market again.
Moneycontrol reported that the company remains about 95 per cent promoter-owned and is expected to dilute around 10 per cent of its equity in the offering, with proceeds earmarked for further acquisitions and debt reduction. The current adviser line-up is also different from the one attached to the 2025 filing: Moneycontrol named Nuvama, JM Financial and Emirates NBD on the latest proposal, while Mint said the earlier attempt had included JM Financial, Motilal Oswal, Nuvama, IIFL Securities and ICICI Securities. In recent months the balance sheet has also been bolstered privately, with the Adar Poonawalla Family Office investing Rs 700 crore in July and Motilal Oswal Group committing Rs 1,500 crore in August through compulsorily convertible debentures.
Whether the share sale reaches investors on the timetable now being discussed will still depend on both regulation and market sentiment. But the direction of travel is clearer than it was a year ago: a listing once framed as a fund-raise for new solar and power assets is now being presented as the next step for a much larger group stitched together through rapid acquisitions, manufacturing expansion and fresh private capital. If the papers are filed in the coming weeks, the market will get its first formal look at whether that enlarged story can justify one of the biggest renewable energy IPO ambitions yet seen in India.
