Failure to Demonstrate Declared Capacity Attracts Strict Penalty Without Mens Rea, Distinct From Gaming: Supreme Court in PSPCL v. Talwandi Sabo Power [2026 INSC 515]

In Punjab State Power Corporation Limited v. Talwandi Sabo Power Limited & Ors. (2026 INSC 515), the Supreme Court held that demonstration of declared capability under Regulation 11.3.13 of the Punjab State Grid Code, 2013 is a stand-alone provision carrying its own penalty, attracting strict liability if the declared capability is not achieved within four time blocks of the notice, and that it must not be mixed up with gaming, which requires mens rea, illegal enrichment and an inquiry complying with natural justice (paras 19, 22–25, 31–32). On the spreadsheets for 15, 17, 24 and 31 January 2017, the failure to demonstrate stood established (paras 33–36). A Bench of Justice Sanjay Kumar and Justice K. Vinod Chandran allowed the appeals of the PSLDC and PSPCL (paras 38–39).

Status: APTEL's order set aside; order of the Punjab State Electricity Regulatory Commission restored, with modification of its findings that intention and motive to make money are necessary ingredients; penalty and resultant interest liability affirmed; surcharge paid on account of the penalty deductions to be refunded to PSPCL with interest; Civil Appeal Nos. 7432 and 7436 of 2025 allowed (paras 38–39).

Headnote: Failure to Demonstrate Declared Capability Under the Grid Code

Electricity Act, 2003 – Section 32 – Punjab State Grid Code, 2013 – Regulations 11.3.4, 11.3.12, 11.3.13 and 11.5(xi) – Power Purchase Agreement – Declared capability – Demonstration notice by SLDC – Misdeclaration – Gaming – Deviation – DSM Regulations, 2014 – Fourth time block – Ramp-up rate – Strict liability – Civil penalty – Mens rea not required.

Held: (i) Gaming is an intentional misdeclaration of a parameter related to the commercial mechanism to make an undue commercial gain; it requires mens rea coupled with illegal enrichment, found in an inquiry complying with natural justice (paras 19, 27).

(ii) Demonstration of declared capability under Regulation 11.3.13 is a stand-alone provision with its own penalty; gaming and failure to demonstrate are different misdeclarations with different consequences, the former requiring mens rea and the latter inviting strict liability (paras 20, 22, 25).

(iii) On a demonstration notice, the declared capability must be achieved within the fourth time block, counting the block in which the notice is received as the first, as mandated by Regulation 11.5(xi); APTEL was wrong to hold that this sub-clause applies only to revision of schedules (paras 23–24, 31).

(iv) The 1% per minute ramp-up rate in Regulation 5.3.8, which falls under "Governor Action", does not govern demonstration of declared capability (para 26).

(v) Deviation is governed by the DSM Regulations, which do not cover demonstration of declared capability or gaming; a deviation simpliciter is neither gaming nor misdeclaration (paras 24–25).

(vi) Following Union of India v. Dharamendra Textile Processors, the penalty under Regulation 11.3.13 is a civil liability flowing from a contractual obligation; it is imperative on default and needs no finding of mens rea or profiteering (para 32).

Key Holdings of the Supreme Court

• Gaming requires mens rea and illegal enrichment, established in an inquiry that complies with natural justice; the notice in this case was not one for gaming (paras 19, 27).
• The SERC erred in treating the allegation as gaming and in requiring intention and a motive to make money, though it rightly upheld the penalty (para 20).
• Regulation 11.3.13 is a stand-alone provision; failure to demonstrate declared capability invites strict liability (paras 22, 31).
• Demonstration must be achieved within the fourth time block from the block in which the notice is received, under Regulation 11.5(xi) (paras 23–24, 31).
• The ramp-up rate and the DSM Regulations do not govern demonstration of declared capability (paras 24, 26).
• The penalty is a civil liability arising from contract; mens rea is not required (para 32).
• The CERC order in TPDDL and the APTEL decision in PSEB v. CERC were misread or inapplicable (paras 28–29, 37).

Brief Facts of the Case

Talwandi Sabo Power Limited (TSPL), a State generating station, supplies power to PSPCL under a PPA providing for fixed capacity charges on declared capability and variable charges on scheduled energy. The Punjab State Load Despatch Centre (PSLDC) found misdeclaration of declared capacity on five days, 10.08.2015 and 15, 17, 24 and 31 January 2017, and levied a penalty of Rs.162,74,72,865/- by Memo No. 278 dated 15.03.2017, of which Rs.74,27,27,159/- was deducted from pending bills (paras 1–2).

On directions of the High Court the matter went to the Commercial and Metering Committee, then to the State Grid Code Review Committee, and finally to the SERC. The SERC affirmed misdeclaration on the four January 2017 dates but rejected the finding for August 2015 (paras 1, 12).

The SERC noted that in December 2016 the generating station failed to deliver requisite generation in 387 of 459 time blocks, and that warning notices led it to lower its declared capability rather than increase generation (para 12). APTEL reversed the SERC, holding that no time limit applies to demonstration, that the notices did not specify a time block, and that capability was demonstrated on the same day with deviations of around 1%. It directed refund of the penalty adjusted in the bills (paras 13–14). PSLDC and PSPCL appealed (para 1).

Issues Before the Supreme Court

1. Whether failure to demonstrate declared capability under Regulation 11.3.13 requires a finding of mens rea and illegal enrichment, as in the case of gaming (paras 19–22, 32).
2. Within what time the declared capability must be demonstrated on receipt of a notice from the SLDC (paras 23–24, 26, 31).
3. Whether the DSM Regulations or the CERC and APTEL decisions relied on by the generating station govern the issue (paras 24, 28–29, 37).
4. Whether the failure to demonstrate was established on the four dates in January 2017 (paras 33–36).

Court's Findings and Reasoning

Past conduct no answer (paras 15, 29): The plea of force majeure was hastily given up on the Court's query and was not raised before the SERC or APTEL. Past fidelity in the relationship cannot justify deviation from express contractual terms where strict liability applies.

PPA and scheduling framework (paras 16–18): Fixed charges are paid on contracted capacity at normative availability, with incentives and disincentives on annual availability. The SG Code sets out day-ahead declaration and scheduling, and Regulation 11.3.4 lists the SLDC's separate duties, including real-time monitoring and checking against gaming.

Gaming needs mens rea (paras 19–20, 27): Gaming is an intentional misdeclaration to make undue commercial gain and must be found after notice and an inquiry. The SERC mistook the present allegation for gaming in requiring intention and a motive to make money, though it rightly upheld the penalty.

Demonstration is a separate, strict obligation (paras 21–22, 25): Regulation 11.3.13 requires the generating station to demonstrate declared capability whenever asked, failing which capacity charges are reduced as penalty in geometric progression. It is a stand-alone provision; a failure to demonstrate does not necessarily mean gaming, and a deviation simpliciter is neither.

Fourth time block applies (paras 23–24, 31): The Court rejected APTEL's view that Regulation 11.5(xi) applies only to revision of schedules. Demonstration tests the system's response on a real-time basis, which has to materialise within four time blocks, counting the block in which notice is received as the first.

Ramp rate and DSM Regulations (paras 24, 26): The ramp-up rate under Regulation 5.3.8 relates to governor settings and is not applicable. Under Regulation 6.1 of the DSM Regulations, declaration of capacity, scheduling and elimination of gaming are left to the Grid Code.

Precedents misread (paras 28–29, 37): The observation in TPDDL that capability is declared on the basis of fuel and machinery did not mean misdeclaration can be found only when coal is short or the plant is under repair. PSEB v. CERC concerned fuel substitution in gas and liquid fired plants and was inapplicable.

Civil liability (para 32): Applying Dharamendra Textile Processors and SEBI v. Sri Ram Mutual Fund, the penalty under Regulation 11.3.13 arises from breach of a civil obligation under the contract and is imperative on default, without any finding of mens rea.

Facts on the four dates (paras 30, 33–36): On 15.01.2017 the revised capability of 1841.40 MW was not achieved at all that day. On 17.01.2017, after the notice, the station sought downward revision to 250 MW and then 150 MW. On 24.01.2017, 1650 MW was never achieved. On 31.01.2017 the capability was reached only in the 7th time block from the first notice. Misdeclaration on each day stood established unequivocally.

Final Outcome and Directions

• APTEL's order set aside and the SERC's order restored (para 38).
• The SERC's findings that Regulation 11.3.13 provides the procedure for gaming, and that deliberate intention and motive to make money are necessary ingredients for the penalty, modified (para 38).
• The penalty imposed and resultant interest liability, if any, affirmed (para 38).
• Surcharge paid on the bills only because of the penalty deductions, after APTEL's reversal, to be refunded to PSPCL with interest/surcharge at the same rate (para 38).
• Appeals allowed; pending applications disposed of (paras 39–40).

Legal Principle Laid Down

Under the Punjab State Grid Code, failure of a generating station to demonstrate its declared capability within four time blocks of an SLDC notice attracts the penalty under Regulation 11.3.13 as a strict, civil liability, without any finding of mens rea or profiteering. Gaming is a distinct misdemeanour requiring intention, illegal enrichment and an inquiry in compliance with natural justice, and deviation is a separate matter governed by the DSM Regulations (paras 22–25, 27, 31–32).

Important Paragraphs of the Judgment

Verbatim extracts from the judgment. For the full text, refer to the judgment PDF below.

Para 15: "Morality in past conduct, though attractive by itself, can seldom be a justification for deviation from express terms of a contract especially when there is a strict liability enforced without reference to a guilty mind; the mens rea."

Para 19: "We fully concur with the respondent’s contention that gaming requires mens rea coupled with illegal enrichment which requires an inquiry fully complying with the principles of natural justice."

Para 22: "The demonstration as required by Regulation 11.3.13 is a stand-alone provision, the penalty for which is ingrained therein."

Para 25: "A conspectus of the above, according to us, would indicate that a deviation simplicitor would neither amount to gaming nor misdeclaration for failure to demonstrate declared capability."

Para 31: "The demonstration of declared capability invites strict liability if the declared capability is not achieved within four time-blocks, treating the time block in which the notice of demonstration is received as the first block."

Para 32: "The said measure of imposition of penalty does not call for any finding of mens rea or a finding of illegal profiteering as would be required when there is an allegation of gaming."

Practical Impact of the Ruling

• For generating companies: Declared capability must be backed by real ability to generate; a demonstration notice must be met within four time blocks, and lowering the declaration after the notice will not help (paras 23, 31, 34).
• For distribution companies and SLDCs: A penalty for failure to demonstrate can be imposed without an inquiry into intent; gaming allegations, however, need notice and a full inquiry (paras 19, 25, 32).
• For regulators and APTEL: Gaming, deviation and failure to demonstrate are distinct breaches and should not be intermingled (paras 22, 25, 27).
• For consumers: Penalties recovered from generators flow into tariff accounting, as argued by PSPCL (para 5).

FAQs on Failure to Demonstrate Declared Capability

1. What did the Supreme Court decide in PSPCL v. Talwandi Sabo Power?

It set aside APTEL's order and restored the SERC's finding of misdeclaration on four days in January 2017, affirming the penalty on the generating station (paras 36, 38).

2. Is mens rea needed for a penalty under Regulation 11.3.13 of the Punjab Grid Code?

No. The penalty is a civil liability arising from a contractual obligation and is imperative on failure to demonstrate; no finding of mens rea or profiteering is required (paras 22, 32).

3. How is gaming different from failure to demonstrate declared capability?

Gaming is an intentional misdeclaration to make undue commercial gain and requires mens rea, illegal enrichment and an inquiry; failure to demonstrate attracts strict liability (paras 19, 22, 27).

4. Within what time must declared capability be demonstrated?

Within the fourth time block, treating the block in which the notice is received as the first, as per Regulation 11.5(xi) (paras 23–24, 31).

5. Do the DSM Regulations govern demonstration of declared capability?

No. Deviation is governed by the DSM Regulations, but Regulation 6.1 leaves declaration of capacity, scheduling and gaming to the Grid Code (para 24).
