Punjab State Power Corporation Limited v. Talwandi Sabo Power Limited
(2026) INSC 515
Key Issue / Question of Law
Whether the failure of a generating station to demonstrate its declared capacity (DC) when asked by the State Load Despatch Centre (SLDC) under Regulation 11.3.13 of the Punjab State Grid Code, 2013 constitutes a strict liability inviting penalty without proof of mens rea or illegal enrichment, and whether such demonstration must be achieved within the fourth time block from receipt of the notice under Regulation 11.5(xi).
Ratio Decidendi
Demonstration of declared capability under Regulation 11.3.13 of the Punjab State Grid Code, 2013 is a stand-alone provision that invites strict liability. The penalty for failure to demonstrate is ingrained in the regulation itself and does not require a finding of intentional misdeclaration or illegal enrichment. Gaming under Regulations 11.3.4 and 11.3.12 requires mens rea and illegal enrichment and is distinct from failure to demonstrate declared capability. The fourth time block under Regulation 11.5(xi) — treating the time block in which the notice is received as the first — is relevant for demonstration of declared capability. The obligation to generate power in accordance with declared capability flows from the Power Purchase Agreement, a civil obligation; breach thereof attracts penalty without anything more, regardless of mens rea. The decision in TPDDL v. PPCL (CERC) does not lay down that misdeclaration can be established only by showing absence of coal stock or plant shutdown; those are merely illustrative of grounds for declaration, not exhaustive of circumstances constituting misdeclaration.
Holding / Decision
The Supreme Court allowed the appeals, set aside the order of the Appellate Tribunal for Electricity (APTEL), and restored the order of the Punjab State Electricity Regulatory Commission (SERC) finding misdeclaration of declared capacity on four days in January 2017. The Court held that the demonstration of declared capability must be achieved within the fourth time block from receipt of notice. The failure to demonstrate constitutes strict liability. The penalty imposed by the SERC was affirmed. The Court modified the SERC order to the extent that it conflated demonstration of declared capability with gaming; the two are distinct. The consequences of reversal regarding interest and surcharge were directed to follow.
Background & Facts
The Punjab State Load Despatch Centre (PSLDC) found that Talwandi Sabo Power Limited (TSPL/SGS), a generating station, had misdeclared its Declared Capacity (DC) on four days in January 2017 (15th, 17th, 24th and 31st). A penalty of Rs. 162.74 crores was levied, of which Rs. 74.27 crores was deducted from pending bills. The matter was referred to the Punjab State Electricity Regulatory Commission (SERC), which affirmed the finding of misdeclaration on the four days and upheld the penalty. The Appellate Tribunal for Electricity (APTEL) reversed the SERC order, holding that the Grid Code did not specify a time limit for demonstration of declared capability, that ramp up rate and 4th time block did not apply, and that misdeclaration required a finding of intentional gaming with illegal enrichment. The PSLDC and PSPCL appealed to the Supreme Court.

Key Conditional Rule / Important Caveat
This judgment applies ONLY where (a) the generating station has declared a certain capacity (DC) for a day, (b) the SLDC issues a notice requiring demonstration of that declared capability under Regulation 11.3.13 of the Grid Code, (c) the generating station fails to achieve the declared capacity within the fourth time block from receipt of the notice (counting the time block in which the notice is received as the first), and (d) the generating station does not have a valid force majeure or prior communicated revision of declared capacity. If the generating station had validly revised its declared capacity before the demonstration notice was issued, or if the demonstration notice itself was not properly served, or if the SLDC's schedule was lower than the declared capacity and the generating station had technical issues communicated in advance, the strict liability may not apply. The judgment does NOT apply to allegations of gaming under Regulation 11.3.12, where mens rea and illegal enrichment must be proved after an inquiry.
Cases Distinguished
- TPDDL v. PPCL (Petition No. 199/MP/2019, CERC, 29.11.2023) — Distinguished and corrected: the observation that misdeclaration requires absence of coal stock or plant shutdown was merely illustrative, not exhaustive; misdeclaration can be established by failure to demonstrate declared capability under Regulation 11.3.13 regardless of coal stock or plant condition.
Cases Cited
- Union of India v. Dharamendra Textile Processors (2008) 13 SCC 369 — Held that penalty arising from breach of civil obligation does not require proof of mens rea; the mere use of the word 'penalty' is not determinative of whether proceedings are criminal or quasi-criminal.
- Chairman, SEBI v. Sri Ram Mutual Fund (2006) 5 SCC 361 — Held that mens rea is not a straitjacket formula; the language and scheme of the Act determine whether mens rea is required for penalty.
- PSEB v. CERC (Appeal No. 79 of 2007, APTEL, 11.12.2007) — Distinguished: the 1% deviation in that case was found to be within practical limits due to calorific value variations in gas fuel; not applicable to coal-based generation in the present case.
- Excel Crop Care Ltd. v. CCI (2017) 8 SCC 47 — Distinguished: the principle that penal provisions should be interpreted in favour of the assessee applies when two reasonable interpretations are possible; here, the interpretation of Regulation 11.3.13 is clear and admits no ambiguity.
