Introduction

The case of Adani Power (Mundra) Limited v. Central Electricity Regulatory Commission Secretary And Others adjudicated by the Appellate Tribunal for Electricity on June 7, 2021, marks a significant development in the interpretation of 'Change in Law' provisions within Power Purchase Agreements (PPAs). This judicial decision revolves around cross appeals challenging the legality, propriety, and validity of certain compensatory claims denied by the Central Electricity Regulatory Commission (CERC).

The primary parties involved include Adani Power Mundra Limited (the Appellant Generator) and Uttar Haryana Bijli Vitran Nigam Ltd. & Dakshin Haryana Bijli Vitran Nigam Ltd. (the Respondent Discoms). The crux of the dispute centers on the entitlement of the Appellant to compensation for additional expenditures arising from statutory changes post the bid cut-off date.

Summary of the Judgment

The Appellant, Adani Power Mundra Limited, sought compensation for various 'Change in Law' events as defined in Article 13 of their PPA dated August 7, 2008. These changes included new taxes, levies, and adjustments in transportation charges affecting the cost structure post the bid deadline of November 19, 2007.

CERC, in its impugned order dated February 6, 2017, allowed certain claims while rejecting others on grounds deemed arbitrary and untenable. The Tribunal, upon reviewing the cross appeals, partially allowed the Appellant's claims related to the increase in Busy Season and Development Surcharges on coal transportation, as well as Carrying Cost on deferred payments. However, claims pertaining to increases in Surface Transportation and Sizing Charges of coal were dismissed, aligning with previous Tribunal decisions.

The Tribunal emphasized that modifications introduced by Indian Governmental Instrumentalities like the Ministry of Railways and Coal India Limited post the cut-off date qualify as 'Change in Law' per the PPA terms, warranting compensatory relief.

Analysis

Precedents Cited

The judgment references several pivotal cases that shaped its outcome:

• Kusum Ingots & Alloys v. Union of India [(2004) 6 SCC 254]: Established that executive instructions without statutory backing can constitute 'Law' if they function as subordinate legislation.
• Energy Watchdog v. CERC [(2017) 14 SCC 80]: Affirmed that policy documents like the Tariff Policy issued under statutory authority possess the force of law.
• Uttar Haryana Bijli Vitran Nigam Ltd. v. Adani Power Ltd. [(2019) 5 SCC 325]: Clarified the entitlement to Carrying Cost under the restitutionary principles of Article 13.2.
• Sasan Power Ltd. v. CERC [2017 ELR APTEL 508]: Held that compensation must be awarded for 'Change in Law' events to prevent the clause from becoming otiose.
• Adani Power Rajasthan Ltd. v. RERC (14.08.2018): Confirmed that increases in transportation surcharges post-cut-off qualify as 'Change in Law' events.

Legal Reasoning

The Tribunal dissected the definition of 'Law' within the PPA, affirming its inclusive nature encompassing all governmental instruments with legal force. It underscored that any alteration in taxes, duties, or levies instituted after the cut-off date organically disrupts the economic equilibrium envisaged at the contract's inception.

For the claims to qualify as 'Change in Law' events, the following criteria must be met:

1. The change must occur post the designated cut-off date.
2. It must be instituted by an Indian Governmental Instrumentality.
3. It should result in additional recurring or non-recurring expenditure or affect the seller's income.

The Tribunal meticulously evaluated each claim against these benchmarks, granting relief where the criteria were unequivocally satisfied.

Impact

This landmark judgment fortifies the stance that infrastructural and policy-induced changes by governmental bodies post-contractual obligations can warrant compensation under PPAs. It sets a clear precedent for future litigations, ensuring that power generators are shielded from unforeseen legislative shifts that could inflate operational costs beyond the scope of original bid terms.

Moreover, it delineates the boundaries of 'Change in Law' provisions, providing a robust framework for interpreting similar clauses in future PPAs, thereby promoting contractual stability and predictability in the power sector.

Complex Concepts Simplified

Conclusion

The judgment in Adani Power (Mundra) Limited v. CERC underscores the judiciary's commitment to upholding contractual fairness amidst legislative evolutions. By affirming the broad interpretation of 'Law' within PPAs and recognizing the financial strains imposed by post-contractual legislative changes, the Tribunal ensures that power generators are not left vulnerable to extraneous governmental policies.

This decision not only clarifies the applicability of 'Change in Law' provisions but also reinforces the imperative for clear and comprehensive contract drafting, especially concerning risk allocation for potential legislative alterations. Stakeholders in the power sector must heed this precedent, ensuring due diligence in anticipating and mitigating future legislative impacts within their contractual frameworks.
