In Punjab State Power Corporation Limited v. Talwandi Sabo Power Limited & Ors. (2026 INSC 515), the Supreme Court restored a significant penalty against a power generating station for failing to demonstrate its “Declared Capacity” on four days in January 2017. The Court established that penalties for the failure to prove declared capability under the Punjab State Grid Code are a matter of strict liability designed to ensure grid discipline and protect consumers from paying for non-existent power. Crucially, the Court ruled that, unlike the concept of “gaming,” a penalty for this type of misdeclaration does not require proof of mens rea (guilty intent) or deliberate illegal enrichment.
Summary of the Case
- The Regulatory Context
- Two-Part Tariff: Power purchase agreements typically involve a fixed charge based on “Declared Capacity” (the power a generator says it can provide) and a variable charge for actual energy supplied.
- Deemed Generation: Even if the State does not draw the full declared amount, it must pay fixed charges for the “deemed generation.” This creates an incentive for generators to declare more capacity than they actually possess to maximize profit at the expense of consumers.
- The Check: To prevent “misdeclaration,” the State Load Despatch Centre (PSLDC) has the statutory power to issue a notice requiring a generator to demonstrate its declared capability within a specific timeframe (usually by the 4th time block after notice).
- The Dispute and Procedural History
- Misdeclaration Found: In January 2017, the PSLDC found that Talwandi Sabo Power Limited (the SGS) failed to achieve its declared capacity on four separate dates. Consequently, a penalty of approximately Rs. 162.74 crores was levied.
- Conflicting Rulings: The Punjab State Electricity Regulatory Commission (SERC) affirmed the penalty. However, the Appellate Tribunal for Electricity (APTEL) reversed the decision, ruling that misdeclaration can only be established if there is evidence of “gaming”—meaning a deliberate, fraudulent intent to make money without the technical ability to generate power.
- Supreme Court’s Legal Reasoning
- Strict Liability vs. Intent: The Court held that “gaming” and the “failure to demonstrate declared capability” are distinct misdemeanors. While Regulation 11.3.12 (gaming) requires proof of intent, Regulation 11.3.13 (demonstration of capability) is a standalone provision of strict liability.
- Contractual Obligation: The Court reasoned that since fixed charges are paid based on a generator’s declaration, the inability to meet that declaration upon notice is a breach of a civil/contractual obligation that “attracts penalty, without anything more”.
- Technical Failures: On the dates in question, the SGS had units under “reserve shutdown” or experienced technical faults that prevented them from reaching their declared generation levels within the required time blocks. The Court found these failures were established “unequivocally” .
- Final Order The Supreme Court allowed the appeals, set aside the APTEL’s judgment, and restored the SERC’s penalty order . It directed that any penalty amounts previously refunded to the generator following the APTEL decision must be returned to the State Power Corporation with applicable interest/surcharges .
