The Madras High Court has affirmed that a power supplier cannot unilaterally increase tariffs under a fixed-term contract without contractual justification, nor terminate supply before affording the consumer due process. The judgment reinforces that arbitral awards will not be disturbed unless they exhibit patent illegality or perversity, and that breach by one party precludes reliance on contractual remedies for non-payment.
Background & Facts
The Dispute
The dispute arose from a three-year power supply agreement dated 18.04.2018 between OPG Power Generation Pvt. Ltd. (appellant) and Shree Karthik Papers Ltd. (respondent). The agreement fixed the electricity tariff at Rs.5.75 per unit and defined billing cycles from the 28th of one month to the 27th of the next, with payment due within seven days of invoice issuance. On 19.09.2018, the appellant unilaterally increased the tariff to Rs.6.15 per unit, effective 28.09.2018, citing Clause 11.8 of the agreement which permitted tariff revision upon changes in fuel cost or law. The respondent protested, asserting no such change had occurred and demanding maintenance of the original rate. When payment for the August - September 2018 billing cycle was not made within seven days, the appellant ceased power supply on 28.09.2018, forcing the respondent to procure power from TANGEDCO at higher rates.

Relief Sought
The appellant sought to set aside the arbitral award under Section 34 of the Arbitration and Conciliation Act, 1996, arguing that the arbitrator erred in holding the supplier liable for breach and in awarding damages for alternate power procurement. The respondent sought enforcement of the award and compensation for losses incurred.
The Legal Issue
The central question was whether Clause 11.8 of the power supply agreement permitted unilateral tariff revision without proof of increased fuel costs, and whether the supplier’s cessation of power prior to expiry of the seven-day payment window constituted a breach that precluded reliance on contractual remedies for non-payment.
Arguments Presented
For the Appellant
The appellant contended that Clause 11.8 granted it an absolute right to revise tariffs upon changes in fuel prices, and that the respondent’s failure to pay within seven days justified power cutoff under Clause 3.8. It relied on Timbola Irmaos Ltd. v. Jorge Anibal Matos to argue that contractual rights must be enforced even if one party suffers loss, and cited Pulavarti Sitaramamurthy to assert that motive alone cannot establish breach. It further argued that the arbitrator ignored the clear terms of the agreement and that the award was irrational.
For the Respondent
The respondent countered that Clause 11.8 required actual changes in fuel cost or law, which the appellant failed to substantiate with documentation. It emphasized that the agreement mandated notice and opportunity to dispute invoices under Clause 4.6.1, and that termination under Clause 3.8 required compliance with procedural safeguards. It relied on Sikkim Subba Associates and Associate Builders v. DDA to argue that the award was neither perverse nor illegal, and that the appellant’s initial breach barred it from invoking remedies for subsequent non-payment.
The Court's Analysis
The Court conducted a rigorous textual and contextual analysis of the agreement, particularly Clause 11.8 and Clause 3.8. It held that Clause 11.8 was not a blank cheque for tariff hikes but was conditional upon demonstrable changes in fuel cost, transmission charges, or law. The appellant produced no evidence - such as coal price indices, fuel procurement records, or regulatory notifications - to substantiate its claim of increased generation costs. The Court observed:
"The claim for increase in the landed cost of coal was only an after thought. The appellant had not produced any document to show that there was an increase in the cost of generation of coal."
Regarding Clause 3.8, the Court emphasized that even if non-payment occurred, the agreement required the supplier to act at its "sole option and discretion" - but not arbitrarily. The unilateral cessation of supply on 28.09.2018, before the seven-day payment window expired, was held to be a clear breach. The Court distinguished Timbola Irmaos by noting that in that case, the plaintiff’s failure to provide facilities caused the delay; here, the supplier’s own breach triggered the dispute.
The Court further applied the test of perversity from Associate Builders v. DDA and PSA Sical Terminals, concluding that the arbitrator’s findings were neither based on no evidence nor irrational. The award was grounded in the contractual framework, and the arbitrator correctly held that breach by the supplier precluded it from invoking remedies for non-payment. The Court reiterated the narrow scope of judicial review under Section 34, citing Dyna Technologies v. Crompton Greaves:
"Arbitral awards should not be interfered with in a casual and cavalier manner, unless the Court comes to a conclusion that the perversity of the award goes to the root of the matter."
The Court also rejected the appellant’s reliance on motive-based reasoning (Pulavarti Sitaramamurthy), noting that the issue was not intent but contractual compliance.
The Verdict
The appellant’s appeal was dismissed. The Madras High Court upheld the arbitral award, holding that unilateral tariff revision without proof of underlying cost changes constitutes breach of contract, and that cessation of supply before expiry of the contractual payment window precludes reliance on contractual termination clauses. The respondent was entitled to damages for procuring alternate power and increased security deposits.
What This Means For Similar Cases
Contractual Rights Are Conditional, Not Absolute
- Practitioners must demonstrate objective triggers (e.g., fuel cost indices, regulatory orders) before invoking clauses permitting price revision.
- Boilerplate clauses like "change in fuel cost" require contemporaneous, verifiable documentation - oral assertions or generic claims are insufficient.
- Courts will not permit parties to exploit contractual flexibility to circumvent fixed-price obligations.
Breach by One Party Bars Enforcement of Remedies
- A party that commits the first material breach (e.g., unilateral tariff hike) cannot later invoke contractual remedies (e.g., power cutoff) for subsequent non-payment.
- The doctrine of "first in breach" applies strictly in commercial contracts; the breaching party forfeits the right to enforce default provisions.
- Arbitrators and courts will examine the sequence of breaches to determine entitlement to remedies.
Arbitral Awards Are Protected Unless Perverse
-
Challenges under Section 34 must focus on patent illegality or perversity, not factual disagreements.
-
Arbitrators are entitled to interpret ambiguous clauses if their interpretation is plausible and grounded in the contract.
-
Courts will not substitute their view of commercial wisdom for that of the arbitrator absent clear legal error.
-
Always verify contractual triggers before invoking price adjustment clauses.
-
Never terminate supply without confirming full compliance with notice and grace period requirements.
-
Preserve all documentation supporting cost changes - digital records, invoices, and regulatory notices are critical evidence.
