Sembcorp Green Infra IPO: Issue Size, Business, Financials, Risks and Everything You Need to Know

Sembcorp Green Infra Limited sits at an interesting point in India’s renewable energy build out. The company is already a scaled independent power producer, but its next phase is increasingly about more complex projects: hybrid generation, battery storage, round the clock supply and firm and dispatchable renewable energy.

The company’s draft offer document proposes a fresh issue of equity shares aggregating up to ₹3,750 crore. There is no offer-for-sale component. That distinction matters because the IPO is primarily a balance-sheet and growth-capital event rather than a shareholder exit.

As of March 31, 2026, Sembcorp Green Infra had 3.60 GW of operational renewable capacity. It also had 2.61 GW of renewable capacity under construction and 1.43 GWh of battery energy storage capacity under construction. The portfolio spans 105 projects across 13 states and Union Territories.

The central question for investors is therefore not simply whether India needs more renewable energy. It is whether Sembcorp Green Infra can convert a large project pipeline into commissioned capacity while managing debt, execution risk, fixed-tariff contracts and the rising complexity of storage-backed power.

Sembcorp Green Infra IPO dates and launch details

The DRHP is dated 26 August 2026 and was subsequently displayed on SEBI’s public-issue filing system on 1 September 2026. The IPO remains at the draft stage. Final issue dates, price band and minimum bid lot have not yet been announced.

Because the issue is entirely fresh capital, the proceeds are intended to enter the company rather than go to selling shareholders. The proposed ₹3,000 crore debt reduction is particularly relevant for a capital-intensive renewable platform where project growth has been accompanied by rising borrowings.

About Sembcorp Green Infra 

Sembcorp Green Infra is a renewable independent power producer focused on developing, constructing, operating and maintaining utility scale renewable projects in India. The platform traces its operating history to 2005 and is backed by Singapore-headquartered Sembcorp Industries through Sembcorp Utilities.

Its portfolio is no longer limited to conventional standalone wind and solar. The company is building capabilities across hybrid power, battery energy storage systems (BESS), round the clock supply and firm and dispatchable renewable energy. These projects combine generation technologies and storage to supply power with greater predictability than standalone wind or solar.

The operating model also has a meaningful in-house element. Sembcorp uses internal engineering, project execution and O&M capabilities, supported by digital monitoring and predictive-maintenance systems. This becomes more important as the portfolio grows and as projects combine multiple technologies.

How does Sembcorp Green Infra make money?

The core revenue engine is the sale of electricity under power purchase agreements. A large proportion of capacity is contracted with central and state government entities, while the company also serves private offtakers. Long-duration PPAs can improve revenue visibility, but fixed tariffs limit the ability to pass through higher costs.

As of March 31, 2026, 85.40% of operational capacity and 90.24% of total contracted capacity were under PPAs with central or state government entities. The top 10 offtakers contributed 75.10% of gross billed power-generation revenue in FY26. This combination creates long-duration contracted cash flows, but it also makes counterparty concentration an important risk to track.

Sembcorp Green Infra financials

The restated consolidated numbers show modest revenue growth in FY25 followed by a stronger step-up in FY26. Profitability, however, has not moved in a straight line.

Revenue from operations increased by about 3.1% in FY25 and 14.4% in FY26. Over FY24-FY26, the two-year revenue CAGR was about 8.6%. PAT fell 16.8% in FY25 before rebounding 24.2% in FY26 to ₹371.08 crore. The FY26 PAT margin was about 14.0%, compared with 12.9% in FY25 and 16.0% in FY24.

The more important balance-sheet trend is leverage. Total borrowings increased from ₹9,318.76 crore in FY24 to ₹12,623.38 crore in FY26, a two-year CAGR of about 16.4%. That growth reflects the funding needs of a rapidly expanding project portfolio. It also explains why debt repayment is the largest stated use of IPO proceeds.

Cash flow and capex: what investors should focus on

Renewable power is structurally capital intensive. Project cash flows are typically contracted over long periods, but capacity must first be financed, built, connected and commissioned. As Sembcorp Green Infra expands into hybrid and storage-backed projects, capital deployment and debt funding remain central to the financial story.

For investors, the useful monitorable is not only accounting profit. It is how quickly under-construction projects move into operation, how much incremental debt is required before commissioning, and how operating cash generation evolves once those projects begin contributing. The proposed repayment or prepayment of ₹3,000 crore of borrowings could strengthen the balance sheet, although the eventual impact will depend on the final issue size and debt outstanding at the time of the IPO.

Sector and market context

India’s renewable market is moving beyond adding standalone wind and solar capacity. Power buyers increasingly need renewable supply that better matches demand through the day. This is driving more tenders for hybrid projects, round-the-clock renewable power, FDRE and storage-linked configurations.

That evolution creates a larger addressable opportunity for developers that can combine generation technologies, storage, forecasting and execution capabilities. It also raises the bar. Complex projects require stronger engineering, procurement, financing and operating discipline than conventional single-technology assets.

Sembcorp Green Infra’s portfolio positions it in that transition. Its 1.43 GWh of BESS capacity under construction and growing exposure to hybrid and storage-linked projects are therefore strategically important. They also add technology, execution and procurement risks that investors need to assess alongside the growth opportunity.

Key considerations for investors

Strengths

• Scaled renewable platform: 3.60 GW of operational capacity across a broad geographic footprint.

• Large visible build-out: 2.61 GW of renewable capacity and 1.43 GWh of BESS under construction as of March 31, 2026.

• Capabilities across complex projects, including hybrid, RTC, FDRE and storage-backed configurations.

• Long-term contracted model with a high proportion of operational and contracted capacity tied to government entities.

• In-house engineering, O&M and digital asset-management capabilities that can support execution and operating efficiency.

• Sembcorp group parentage, which can support procurement, financing access and operating expertise.

Risks

• Leverage remains high and has risen alongside capacity expansion. Borrowings reached ₹12,623.38 crore in FY26.

• Government offtakers account for a large share of contracted capacity, while the top 10 offtakers contributed 75.10% of FY26 gross billed generation revenue.

• PPAs generally have fixed tariffs, limiting flexibility if operating, financing or procurement costs rise.

• A large under-construction portfolio creates execution, land, transmission, approval, commissioning and cost-overrun risk.

• The top 10 suppliers accounted for 44.90% of total purchases in FY26, creating exposure to equipment availability and supplier concentration.

• Wind and solar generation remain exposed to resource variability, seasonality, curtailment and extreme weather.

• Competitive bidding can compress tariffs and returns, particularly as more developers pursue hybrid and storage-linked tenders.

Opportunities

• More BESS, hybrid, RTC and FDRE tenders could favour developers with multi-technology execution capability.

• Commissioning the current project pipeline can expand the operational earnings base without requiring a new business model.

• Selective acquisitions can supplement greenfield growth where project economics and integration are attractive.

• Digital O&M, forecasting and predictive maintenance can become more valuable as the operating fleet scales.

What does the IPO structure tell us?

The absence of an OFS is notable. The proposed IPO is designed to inject capital into Sembcorp Green Infra, with most of the stated use directed towards reducing borrowings. In practical terms, investors are funding a balance-sheet reset while the company simultaneously carries a sizeable under-construction portfolio.

That makes the post-issue debt trajectory a key monitorable. If debt repayment is followed by disciplined commissioning and operating cash generation, the capital raise can improve financial flexibility. If the next growth cycle quickly rebuilds leverage, the benefit of the IPO-funded deleveraging may be less durable.

Conclusion

Sembcorp Green Infra brings together three features that make the IPO worth studying closely: operating scale, a large under-construction portfolio and a deliberate shift towards complex renewable projects. FY26 showed stronger revenue and PAT growth, but borrowings have also risen materially as the platform has expanded.

The fresh-issue-only structure and proposed ₹3,000 crore debt repayment directly address that leverage. The final assessment, however, will depend on the price band, valuation, the pace at which new projects become operational, the returns earned on storage backed projects and the company’s ability to keep leverage under control through the next phase of growth.
