Section 37 Courts Cannot Re-compute Liquidated Damages When Section 34 Has Plausibly Fixed “Reasonable Compensation” Under Section 74 (JNNSM Solar PPAs as Public-Interest Contracts)

Case: M/S SAISUDHIR ENERGY LTD v. M/S NTPC VIDYUT VYAPAR NIGAM LTD Citation: 2026 INSC 103 Court: Supreme Court of India Date: 30-01-2026

1) Introduction

This Supreme Court decision arises from cross appeals under Section 37 of the Arbitration and Conciliation Act, 1996 (“Act of 1996”), challenging a Delhi High Court Division Bench judgment that had modified the liquidated damages payable for delay in commissioning a solar power project.

The underlying contract was a Power Purchase Agreement (“PPA”) dated 24.01.2012 between M/s Saisudhir Energy Limited (SEL) (Solar Power Developer) and NTPC Vidyut Vyapar Nigam Limited (NVVNL) (nodal agency under the Jawaharlal Nehru National Solar Mission—“JNNSM”). SEL undertook to commission and supply 20 MW solar power by 26.02.2013. SEL missed the deadline: 10 MW commenced from 26.04.2013 (2 months delay), and the remaining 10 MW from 24.07.2013 (about 5 months delay).

The key legal issues were:

• Section 74, Indian Contract Act, 1872: whether NVVNL must prove “actual loss” to recover liquidated damages under the PPA.
• Public interest/public utility: whether a JNNSM solar PPA is a public-interest contract where delay itself implies loss.
• Arbitration court powers: the permissible scope of “modification” under Section 34, and especially the limits of interference under Section 37.

2) Summary of the Judgment

3) Analysis

A. Precedents Cited

1) Kailash Nath Associates v. D. D. A. (2015 INSC 22)

SEL relied on this authority to argue that under Section 74, compensation requires proof of loss, and absent proof NVVNL should get no liquidated damages. The Supreme Court did not treat Kailash Nath Associates v. D. D. A. as controlling on these facts because:

• the dispute involved a contractual clause (Clause 4.6) with a structured liquidated damages mechanism for delay;
• the project served a public-interest objective (promotion of green energy under JNNSM); and
• the Court applied the public utility reasoning (discussed below), shifting emphasis away from strict proof of quantifiable loss.

In effect, Kailash Nath was engaged as SEL’s “proof-of-loss” anchor, but the Court answered it by characterising the contract’s nature and by relying on public-utility logic developed in later/parallel lines of authority.

2) M/s Construction and Design Services v. D.D.A. (2015 INSC 92)

This was the Court’s central doctrinal support on Section 74 in public utility contexts. There, delay in commissioning a sewerage pumping station was treated as inherently harmful (including environmental degradation), making exact proof of loss difficult or artificial.

Here, the Court held the JNNSM solar PPA was not “merely commercial”: it advanced a social/public purpose—green energy—and therefore M/s Construction and Design Services v. D.D.A. “provides sufficient indication” on awarding reasonable compensation where public utility/public interest is involved.

A key move is the Court’s allocation of evidentiary burden: in such cases, the burden lies on the breaching party to show no loss or that the clause is penal. The Court found SEL failed to discharge that burden, particularly because SEL’s argument focused narrowly on NVVNL’s lack of capital investment rather than the broader public-interest harm from delay.

3) Gayatri Balasamy v. ISG Novasoft Technologies Limited (2025 INSC 605)

SEL invoked Gayatri Balasamy to contend that courts cannot conduct merits review or modify awards by re-assessing damages. The Supreme Court, however, used Gayatri Balasamy to support the Single Judge’s Section 34 approach:

• Gayatri Balasamy recognises a limited power of modification under Section 34 (including through severability), to avoid unnecessary re-arbitration and delay;
• the Single Judge’s modification was characterised as applying Clause 4.6.2 to the admitted facts—not a forbidden merits re-trial.

Importantly, the Supreme Court distinguished the Section 34 posture (where limited modification may be justified) from the Section 37 posture (where re-calculation and substitution of a new quantum is far more tightly constrained).

4) Chamundeshwari Electricity Supply Company Limited v. Sai-Sudhir Energy (Chitradurga) Private Limited and another (2025 INSC 1034)

NVVNL relied on this to resist equitable reduction and to argue entitlement to the full contractual liquidated damages. While the Supreme Court did not ultimately grant NVVNL the full claim, the citation served to reinforce that:

• liquidated damages clauses in power/utility contexts are not to be diluted purely by “equity” once breach is clear; and
• the contract governs, subject to Section 74’s “reasonable compensation” ceiling.

The Court’s actual resolution—restoring the Single Judge’s 50% award—shows it accepted the relevance of the contractual framework while still treating “reasonable compensation” as a judicially policed standard.

5) AC Chokshi Share Broker Private Limited v. Jatin Pratap Desai and another (2025 INSC 174)

This precedent was used to delineate the Section 37 appellate function: the Section 37 court must examine whether the Section 34 court exercised its jurisdiction properly and within bounds; it is not to re-adjudicate or replace plausible determinations with its preferred view.

Applying AC Chokshi Share Broker Private Limited v. Jatin Pratap Desai and another, the Supreme Court held the Division Bench crossed the line by “re-work[ing] and re-calculate[ing]” reasonable compensation without finding the Single Judge’s determination arbitrary, perverse, or contrary to the contract.

B. Legal Reasoning

1) Breach and contractual trigger: Clause 4.6

The Court treated delay as undisputed and repeatedly recorded as admitted at all levels (tribunal majority; Section 34; Section 37). Once delay was established, Clause 4.6 (liquidated damages for delayed commencement) was automatically engaged.

2) Section 74: “Reasonable compensation” and proof of loss in public-interest settings

The Court directly engaged Section 74’s structure: compensation is “reasonable” and capped by the sum stipulated; it is not strictly dependent on proof of actual loss. The judgment’s doctrinal pivot is characterisation: the PPA under JNNSM was linked to “public interest” and “environment at large” by promoting green energy.

On that foundation, the Court imported the public utility logic of M/s Construction and Design Services v. D.D.A.:

• in public-interest projects, delay itself is sufficient to infer loss/harm of a kind not easily reducible to precise monetary proof;
• the breaching party must show either (a) no loss was caused, or (b) the stipulated amount is penal.

The Court found SEL’s defence (NVVNL made no investment; thus no capital loss/interest loss) inadequate to rebut the broader public-interest loss from delayed green energy commissioning.

3) Section 34 modification vs Section 37 interference

The Court drew a careful boundary:

• Section 34 may modify an award in a limited way (as recognised in Gayatri Balasamy v. ISG Novasoft Technologies Limited), particularly where it “follows inevitably” from applying the contractual/legal framework to admitted facts and does not require appellate fact-finding.
• Section 37 is narrower: it reviews the propriety of the Section 34 court’s exercise of jurisdiction; it does not permit a fresh re-computation merely because another computation seems preferable.

Thus, while the Single Judge’s grant of 50% of the computed Clause 4.6 entitlement was treated as a permissible “reasonable compensation” calibration, the Division Bench’s later re-calculation to ₹20.70 crores was treated as an impermissible substitution of view—absent any finding that the Section 34 computation was beyond Clause 4.6, arbitrary, or perverse.

C. Impact

1) Tightening Section 37 restraint in quantum re-determinations

The most durable precedent is procedural: Section 37 courts should not re-work damages/compensation once the Section 34 court has adopted a plausible, contract-grounded “reasonable compensation” figure, unless the Section 34 approach is shown to be jurisdictionally flawed, perverse, or contrary to the contract/statute. This is particularly significant because Section 37 appeals often become de facto second rounds on quantum; the judgment discourages that drift.

2) Public-interest character of renewable energy commissioning under government missions

By expressly treating JNNSM-linked commissioning obligations as “definitely in public interest” and linked to environmental goals, the Court positions renewable energy PPAs (at least those structured under such missions and involving nodal agencies) closer to public utility jurisprudence for Section 74 analysis. This may reduce the practical force of “no proof of actual loss” objections in delay disputes, shifting focus to whether the clause is penal or whether the developer can show “no loss.”

3) Contract drafting and dispute strategy

• For procurers/nodal agencies: reinforces enforceability of liquidated damages frameworks for commissioning delays, particularly where public-interest objectives are documented.
• For developers: underscores the need for contemporaneous evidence to show lack of loss/public harm, or that the LD rate is disproportionate/penal—mere “no investment by procurer” may be insufficient.
• For courts: encourages resolution within Section 34’s limited modification framework rather than repeated remands/new arbitrations, but draws a firm line at Section 37.

4) Complex Concepts Simplified

Liquidated damages vs penalty (Section 74)

A liquidated damages clause fixes (in advance) an amount payable on breach—typically for delays. A penalty is an amount so excessive that it is designed to punish rather than compensate.

Under Section 74, even if the contract states a fixed sum, courts award only “reasonable compensation”, not automatically the full stated amount. Proof of exact loss is not always required, especially where the loss is inherently difficult to quantify (as in public utility/environmental contexts).

Section 34 vs Section 37 under the Act of 1996

• Section 34 is the set-aside jurisdiction. After Gayatri Balasamy v. ISG Novasoft Technologies Limited, it includes a limited ability to modify/sever parts of an award within statutory “guardrails,” without acting like a full appeal.
• Section 37 is an appeal, but it is not a second merits hearing. It mainly checks whether the Section 34 court acted within its lawful bounds; it should not replace a plausible Section 34 outcome with another plausible outcome.

“Public utility/public interest” in delay cases

Some projects (sewerage, environment-related works, and—here—renewable energy commissioning under a national mission) have broad societal benefits. In such cases, courts may infer that delay itself causes non-trivial harm, even if it is not easily translated into a balance-sheet loss for the procuring entity.

5) Conclusion

The Supreme Court’s ruling in M/S SAISUDHIR ENERGY LTD v. M/S NTPC VIDYUT VYAPAR NIGAM LTD establishes two major takeaways:

• Substantive: JNNSM solar PPAs can be treated as public-interest contracts; under Section 74, lack of precise proof of “actual loss” will not by itself defeat liquidated damages, and the breaching party bears the burden to show no loss or penalty.
• Procedural (core precedent): once a Section 34 court has plausibly fixed “reasonable compensation” within the contract and Section 74, a Section 37 court should not re-calculate quantum merely by substituting its own view, absent perversity/arbitrariness/jurisdictional error.

In the broader arbitration landscape, the judgment reinforces the architecture of minimal appellate re-evaluation, while acknowledging that calibrated Section 34 modification may sometimes better serve arbitration’s efficiency goals than wholesale setting aside and re-arbitration.
