Indian Oil Corporation Ltd. makes a corporate announcement

The 100 MW wind project is strategically aligned but financially and operationally modest relative to IOCL’s FY2030 ambition. Against IOCL’s stated target of developing 31 GW of renewable energy by 2030, the project represents approximately 0.32% of the target on a nameplate-capacity basis, derived from 100 MW versus 31,000 MW ^[1]. The project is therefore one incremental building block, not a material step-change by itself.

Alignment with IOCL’s renewable roadmap

IOCL has also referred to a planned 650 MW round-the-clock renewable-power requirement for refinery expansion projects ^[6]. On a purely capacity basis, 100 MW would equal approximately 15.38% of that requirement, derived from 100 MW divided by 650 MW. That should not be interpreted as a firm 15.38% energy contribution because the 650 MW requirement is round-the-clock, whereas the project is a wind asset.

Captive power versus grid procurement

The specific captive-versus-grid contribution cannot be quantified from the disclosed information. IOCL has said that Terra Clean is exploring commercial and industrial customers through long-term PPAs under the group-captive open-access model ^[1]. This creates two possible uses for the project:

• IOCL captive use: If the full 100 MW is allocated to IOCL’s refinery or other facilities, its nameplate capacity could represent up to 15.38% of the disclosed 650 MW renewable requirement. The actual energy offset would depend on wind utilisation, transmission and wheeling arrangements, banking, curtailment and the final PPA structure.
• Third-party C&I supply: If the project is contracted under group-captive open access to external C&I consumers, it may support Terra Clean’s renewable-power business without directly reducing IOCL’s own grid purchases.

Accordingly, the project should not be modelled as a confirmed 100 MW reduction in IOCL grid procurement. No asset-specific allocation to IOCL captive loads, annual generation estimate, capacity-utilisation factor, PPA off-taker, or percentage reduction in grid-based procurement has been reported. The disclosed evidence supports strategic alignment with IOCL’s renewable expansion, but not a firm forecast of the project’s captive-power contribution.

The implied value is Rs 7.55 Crores per MW (Rs 755 Crores ÷ 100 MW). However, it is an all-in turnkey contract value, not a clean upfront capital-cost benchmark, because the order includes turbine supply, EPC, commissioning and 10 years of operations and maintenance. ^[5]

Analytical read: the Rs 7.55 Crores/MW figure cannot be labelled either high or low against IOCL’s reported renewable portfolio because a comparable IOCL project-cost figure could not be confirmed. The technology and scope also differ: the order is for utility-scale wind and includes long-term O&M, while IOCL’s sustainability disclosures primarily provide installed capacity and generation. The pure construction cost is therefore not identifiable from the order value; it would be lower than the all-in figure if the O&M component were separately valued, but the split was not disclosed.

The nearest IOCL project-specific reference is its 100 MW Gujarat wind project, for which project activity was reported as underway, but no cost estimate was provided in that disclosure. ^[4]

No—this is better read as an acceleration of IOCL’s existing renewable strategy than as a strategic shift in its renewable mix. The 100 MW wind order is material relative to the operating wind portfolio, but IOCL is pursuing wind, solar and round-the-clock renewable power in parallel rather than replacing solar with wind.

Capacity mix

As of 31 March 2026, IOCL’s reported renewable portfolio comprised 167.60 MW of wind and 90.46 MW of solar, or 258.06 MW in total ^[6].

• The order is a 100 MW turnkey wind project valued at approximately Rs 755 Crores and includes turbine supply, EPC, commissioning and 10 years of operations and maintenance ^[5]. It is an order/project, not yet an operating asset.

†Derived from 167.60 MW wind and 90.46 MW solar ^[6]. ‡Pro forma calculation assuming the project is commissioned and there are no other additions or retirements; derived from the reported capacities ^[6] and the 100 MW order ^[5].

The order would therefore raise the wind-to-solar ratio from approximately 1.85:1 to 2.96:1 on a pro forma basis. However, the project was still under development, while IOCL was also progressing a solar project of around 100 MW in Uttar Pradesh ^[4]. That parallel solar activity argues against interpreting the order as a wholesale pivot toward wind.

Comparison with the Annual Report roadmap

The FY26 Annual Report frames the renewable expansion around capacity scale and firm power requirements:

• IOCL reported a planned 650 MW round-the-clock renewable power requirement for refinery expansion projects through its JV with NTPC Green Energy ^[6].
• Terra Clean had begun development activities for 1 GW of renewable capacity, with preparatory work for an additional 4.3 GW ^[2].
• The Annual Report separately reports the existing wind and solar capacities, but the cited roadmap does not provide a target wind-to-solar ratio or a prescribed wind/solar split for RPO compliance ^{[6] [6] [2]}.
• Accordingly, the 100 MW order can be measured against IOCL’s capacity trajectory, but it cannot be shown to be above or below an Annual Report target mix. The specific RPO capacity target or eligible procurement split could not be confirmed from the reported passages.

Implication: the order meaningfully increases IOCL’s wind exposure and improves its ability to build a larger renewable portfolio, but it does not by itself demonstrate compliance with RPOs. The more relevant benchmarks are commissioning of the 650 MW round-the-clock requirement, execution of Terra Clean’s 1 GW-plus pipeline, and the eventual balance between wind, solar and firmed renewable power.*
