Indian Oil Corporation Ltd. makes a corporate announcement

The 100 MW turnkey wind project has a disclosed contract value of Rs 755 Crores, equivalent to Rs 7.55 Crores per MW on a derived basis. The scope includes turbine supply, EPC, project execution and post-commissioning O&M. ^[1]

Alignment with IndianOil’s renewable-energy roadmap

Analyst read: Strategically, the order is consistent with IndianOil’s renewable-energy expansion. At 100 MW, it is material relative to the company’s reported operating renewable base—roughly two-fifths of the FY25 or FY26 portfolio—but small against the multi-gigawatt roadmap: 1.89% of the 5.3 GW Terra Clean plan and 0.32% of the 31 GW 2030 target, based on the cited capacities.

The key distinction is that the FY25 presentation and FY26 Annual Report provide a portfolio roadmap and development pipeline, not a separately stated annual commissioning target of, for example, “X MW in FY25” or “Y MW in FY26.” FY26 actual renewable capacity was 258.06 MW, after 5.95 MW of solar capacity was commissioned during the year. ^[3] Therefore, the 100 MW should be viewed as a new project order supporting the broader transition plan, rather than as evidence that a specific FY25 or FY26 annual capacity target has been achieved.

Finally, Rs 755 Crores is the disclosed turnkey order value, not necessarily the amount that IndianOil will capitalise directly on its own balance sheet; the project’s final accounting treatment, ownership structure and commissioning date are not specified in the cited announcement.

The disclosures do not establish that the 50 MW project is either direct IOCL-owned PPE or a long-term PPA. The project is being developed through IndianOil NTPC Green Energy Pvt. Ltd. (INGEL), a joint venture with NTPC Green Energy, to support the broader 650 MW round-the-clock renewable-power requirement for refinery expansion projects. INGEL was stated to be on course to commission 50 MW during FY26. ^{[3] [4]}

Accordingly, the appropriate modelling assumption today is “JV-led project; accounting treatment not yet disclosed”, rather than booking the full project as IOCL’s direct renewable-energy asset.

Accounting outcomes under the alternatives

What this means for projected renewable ROCE

The distinction is material:

• Direct ownership creates a front-loaded ROCE drag: capital is invested during construction, depreciation begins after commissioning, and returns improve only as generation and utilization ramp up.
• A PPA or equity-accounted JV structure is more asset-light at the IOCL standalone level. That can make reported ROCE appear stronger, but it does not necessarily mean the underlying project economics are superior; part of the economic cost appears as power expense or through the JV investment rather than as IOCL depreciation.
• The 50 MW project should not be confused with IOCL’s existing renewable portfolio of 258.06 MW, comprising 167.60 MW of wind and 90.46 MW of solar capacity as of FY26. ^[4]

Disclosure limit: IOCL has not separately reported the project’s ownership of the generating assets, PPA terms, project cost, useful life, expected depreciation, or renewable-segment ROCE. The Q1 FY27 segment disclosures identify “Other Business Activities” and refer to power generation, but do not provide a renewable-only asset, depreciation, or ROCE breakout. ^[7] Thus, a project-specific depreciation or ROCE forecast would be premature until the INGEL accounting and commercial structure is disclosed.

Verdict: The 100 MW Terra Clean wind project carries an implied headline cost of approximately Rs 7.55 Crore per MW, but it cannot be compared directly with IOCL’s existing solar/wind portfolio because the sustainability disclosures report installed capacity—not the historical capital invested in those assets.

On the only available directional benchmark, the wind project’s Rs 7.55 Crore/MW is about 51% higher than the reported Rs 5 Crore/MW current development estimate, derived from the two reported figures ^{[8] [10]}. That premium should not be treated as a like-for-like cost overrun: the Rs 755 Crore order includes turnkey execution and a 10-year comprehensive O&M arrangement, whereas the Rs 5 Crore/MW figure is described as a development-cost estimate and may exclude comparable O&M or other scope items.

Hurdle rate or IRR

IOCL’s stated policy position is that investments under its capital-allocation process must pass the company’s internal hurdle rate, but the cited earnings-call commentary gives no numerical hurdle rate or project-level IRR ^[11]. Therefore, a defensible percentage IRR for renewable investments cannot be extracted from these disclosures.

The 8.30% pre-tax discount rate appearing in the FY26 annual report is an accounting valuation input used for value-in-use impairment testing of non-fossil/off-gas facilities ^[12] and windmills ^[12]. It is not identified by IOCL as the hurdle rate or expected IRR for green-energy investments.

Analytical conclusion: the project’s headline cost is above the broad Rs 5 Crore/MW development proxy, but IOCL has not disclosed the historical capex of its 258.06 MW operating portfolio or a numeric renewable-investment hurdle rate/IRR. Any stronger conclusion would require project-level capex, financing structure, capacity-utilisation assumptions, tariff/PPA terms and O&M treatment.
