Sembcorp Green Infra (SGI) has filed a Draft Red Herring Prospectus (DRHP) with the Securities and Exchange Board of India (SEBI) for an initial public offering (IPO) totaling ₹3,750 crore. The issue is structured as 100% fresh equity, with no offer-for-sale (OFS) component from the promoter, Sembcorp Utilities Pte Ltd. The primary objective of the fundraise is the repayment or prepayment of existing borrowings, with ₹3,000 crore (80% of gross proceeds) earmarked for debt reduction across the company and its identified subsidiaries.

Key Financial and Portfolio Metrics

  • Total IPO Size: ₹3,750 crore (100% Fresh Issue).
  • Debt Repayment Earmark: ₹3,000 crore.
  • Operational Capacity: 3.60 GW.
  • Under-Construction Pipeline: 4.04 GW (including 1.43 GWh of battery energy storage).
  • Portfolio Visibility: 81.2% of operational capacity under 25-year Power Purchase Agreements (PPAs).
  • Revenue (FY26): ₹2,652.5 crore.
  • Net Debt/EBITDA (FY26): 5.5x.

IPO Structure and Capital Allocation

The proposed offering is a pure fresh issue of equity shares with a face value of ₹10 each. By eschewing an OFS component, the promoter, Sembcorp Utilities Pte Ltd, will retain its entire pre-issue holding, ensuring all net proceeds flow directly toward strengthening the company’s balance sheet. The filing includes a provision for a pre-IPO placement of up to ₹750 crore; if exercised, this would proportionately reduce the size of the fresh issue.

The capital allocation strategy is centered on aggressive deleveraging. Approximately ₹3,000 crore is designated to retire debt at the company level and across 16 identified subsidiaries. Representative entities in this repayment schedule include Green Infra Wind Solutions, Green Infra Clean Solar Energy, Yarrow Infrastructure, and Vector Green Prayagraj Solar. While revenue grew 14.4% in FY26 to reach ₹2,652.5 crore, SGI’s bottom line has exhibited choppier performance. Profit for the year attributable to shareholders rebounded to ₹346.3 crore in FY26 after a dip in FY25, yet remains below the ₹368.9 crore reported in FY24.

Operational Profile and Renewable Energy Portfolio

Sembcorp Green Infra is currently a top 10 renewable independent power producer in India by operational capacity. Its total pipeline of 7.64 GW is split between 3.60 GW of operational assets and 4.04 GW under construction or development. The construction pipeline is notably sophisticated, comprising 2.61 GW of renewable capacity and 1.43 GWh of battery energy storage systems (BESS). This shift toward “Complex Projects,” including hybrid and storage-linked tenders, reflects a broader industry transition; the Indian market for complex tenders grew from 31.68% in FY21 to 86.94% in FY26.

Operating since 2005, the company maintains a geographically diverse footprint across 13 Indian states, with core concentrations in Rajasthan, Karnataka, and Gujarat. The portfolio’s stability is anchored by long-term PPAs, with 43.22% of operational capacity contracted with central counterparties such as the Solar Energy Corporation of India (SECI) and NTPC. These high-quality offtakers provide the “annuity-like” cash flow security essential for large-scale infrastructure platforms.

Corporate Background and Ownership Structure

Sembcorp Green Infra functions as an indirect subsidiary of the Singapore-listed Sembcorp Industries (SCI). The direct promoter, Sembcorp Utilities Pte Ltd (SCU), holds 100% of the pre-issue equity. This structure provides a direct link to Temasek Holdings, the Singapore government’s investment arm, which maintains a 48.93% stake in the parent entity, Sembcorp Industries.

The company adopted its current name in 2023 following an amalgamation with Green Infra Wind Energy Limited. Despite the move toward public markets, SGI remains heavily reliant on its parent’s financial strength. As of June 30, 2026, Sembcorp Utilities Pte Ltd had extended ₹59,673 crore in corporate guarantees to support the group’s borrowings. The DRHP explicitly states that SGI’s ability to secure further debt financing remains contingent on the continued provision of these guarantees by SCU.
