Tamil Nadu Power Producers Association v. Tamil Nadu Electricity Regulatory Commission: Establishing Verification Procedures for Captive Generation

Introduction

The case of Tamil Nadu Power Producers Association v. Tamil Nadu Electricity Regulatory Commission was adjudicated by the Appellate Tribunal for Electricity on June 7, 2021. The appellant, Tamil Nadu Power Producers Association (TNPPA), challenged an order by the Tamil Nadu Electricity Regulatory Commission (TNERC) dated January 28, 2020, which formulated procedures for verifying the status of Captive Users and Captive Generating Plants (CGPs) in Tamil Nadu. This verification was mandated under previous directives from the Honorable High Court of Madras.

Parties Involved:

Appellant: Tamil Nadu Power Producers Association (TNPPA)
Respondents:
- Tamil Nadu Electricity Regulatory Commission (TNERC)
- Tamil Nadu Generation and Distribution Corporation Limited (TANGEDCO)
- Various captive users and associations representing captive users and CGPs

Summary of the Judgment

The Appellate Tribunal dismissed the appeal filed by TNPPA, setting aside specific directives in the TNERC's January 28, 2020, order. The core issues revolved around the delegation of verification and adjudication powers to TANGEDCO, the linkage of open access approvals to captive status verification, the wrongful classification of Special Purpose Vehicles (SPVs) as Associations of Persons (AOPs), and the retrospective application of draft amendments to the Electricity Rules, 2005.

The Tribunal emphasized the exclusive jurisdiction of TNERC in verifying captive status, reaffirming that TANGEDCO, as a distribution licensee, should not adjudicate in its own cause. Additionally, the Tribunal annulled parts of the TNERC order that improperly linked open access approvals to captive status verification and addressed the misclassification of SPVs.

Analysis

Precedents Cited

The judgment extensively cited various judicial decisions to underline the principles governing delegated legislation, statutory interpretation, and the separation of adjudicatory and administrative functions. Key cases include:

Uma Nath Pandey v. State Of Uttar Pradesh (2009) 12 SCC 40
J Mohapatra and Co. v. State of Orissa (1984) 4 SCC 103
Prism Cement Limited v. MPERC (2018) 179 of 2018
Kadodara Power Pvt. Ltd. v. GERC
Several Supreme Court decisions on the doctrine of per incuriam and retrospective legislation

Legal Reasoning

The Tribunal's reasoning was anchored in statutory interpretation, emphasizing that delegated authorities like TNERC must operate within the confines of the Electricity Act, 2003, and its own regulations. The Tribunal clarified that:

Exclusive Jurisdiction: Verification and adjudication of captive status should remain solely with TNERC, not TANGEDCO.
Statutory Limits: Delegation under Section 97 of the Electricity Act does not extend to adjudicating captive status or imposing charges like CSS (Cross Subsidy Surcharge).
Classification of Entities: SPVs cannot be equated with AOPs, as they are distinct entities with separate legal and operational frameworks.
Non-Retrospective Legislation: The Tribunal held that the TNERC cannot apply draft amendments retrospectively, as they lack legal force until formally notified.
Doctrine of Res Judicata: The Tribunal dismissed arguments based on res judicata and estoppel, indicating that the High Court did not conclusively resolve the jurisdictional issues.

Impact

This judgment has significant implications for the captive power generation sector in Tamil Nadu:

Procedural Clarity: Establishes clear guidelines that TNERC must independently verify captive status without delegating this power to TANGEDCO.
Protection of Rights: Ensures that legitimate captive power producers retain their exemptions from CSS without undue interference or procedural hindrances.
Regulatory Compliance: Reinforces the necessity for state regulatory bodies to adhere strictly to statutory mandates, preventing misuse of delegated powers by entities like TANGEDCO.
Legal Precedence: Sets a precedent for how similar disputes may be adjudicated in the future, reinforcing the separation of administrative and adjudicatory functions.

Complex Concepts Simplified

Captive Generation

Captive Generation refers to power plants set up primarily for the consumption of electricity by the entity(s) that own them. These entities benefit from exemptions like the exemption from Cross Subsidy Surcharge (CSS), provided they meet specific criteria established by law.

Cross Subsidy Surcharge (CSS)

CSS is a levy imposed on open access consumers who do not qualify as captive users. It serves as a means to compensate the state-discoms (TANGEDCO in this case) for losses incurred due to non-captive consumption of power.

Doctrine of Per Incuriam

Per Incuriam is a legal term meaning "through lack of care." A judgment rendered per incuriam is considered invalid because it has overlooked a relevant legal principle or statute, thereby not offering a binding precedent.

Conclusion

The Tribunal's decision in Tamil Nadu Power Producers Association v. TNERC reinforces the sanctity of statutory mandates and the non-delegable nature of certain regulatory functions. By nullifying parts of TNERC's order that improperly delegated verification powers to TANGEDCO and linking open access approvals to captive status verification, the Tribunal ensured that state regulatory bodies operate within their defined legal frameworks. This not only protects the interests of legitimate captive power producers but also upholds the principles of transparency and fairness in the electricity sector's regulatory landscape.
