Failure to Demonstrate Declared Capacity Attracts Strict Liability, No Mens Rea Required: Supreme Court
A Supreme Court bench of Justices Sanjay Kumar and K. Vinod Chandran holds that penalty for failing to demonstrate declared generation capacity is a civil strict-liability obligation, distinct from gaming.
The Supreme Court has restored a penalty of over Rs. 162 crore imposed on Talwandi Sabo Power Limited (TSPL), a State Generating Station in Punjab, for failing to demonstrate its declared generation capacity on four days in January 2017. Setting aside the order of the Appellate Tribunal for Electricity (APTEL), the Court held that the obligation to demonstrate declared capacity under Regulation 11.3.13 of the Punjab State Grid Code, 2013 is a stand-alone provision attracting strict civil liability, no finding of guilty intent or illegal enrichment is required. The judgment draws a sharp three-way distinction between gaming, deviation, and failure to demonstrate declared capacity, clarifying that each is governed by a separate regulatory regime with different consequences and different thresholds of proof.
How the Dispute Reached the Court
TSPL operates three generating units of 660 MW each under a Power Purchase Agreement (PPA) with Punjab State Power Corporation Limited (PSPCL). The Punjab State Load Despatch Centre (PSLDC) exercises statutory functions under Section 32 of the Electricity Act, 2003 to oversee, monitor and control the availability schedule and despatch of electricity generated by TSPL and supplied to PSPCL.
Under the PPA, TSPL receives a two-part tariff: fixed capacity charges based on declared capacity, and variable charges on energy actually scheduled for supply. Because PSPCL pays fixed charges even when it draws less than the declared capacity, a benefit termed deemed generation, the regulatory framework requires TSPL to declare its capability faithfully and to be able to demonstrate that capability whenever the PSLDC demands it.
In December 2016, the PSLDC noticed a recurring pattern of generation falling below TSPL's declared schedule. Warning notices were issued. On 30 December 2016, under-injection of up to 27% was recorded in a single time log. Rather than increasing generation, TSPL lowered its declared capability. The PSLDC's analysis showed that TSPL failed to deliver requisite generation in 387 out of 459 time blocks during December 2016 an under-generation rate of 84.13% of the time blocks corresponding to declared capability.
This led to demonstration notices being issued on four dates in January 2017: 15 January, 17 January, 24 January, and 31 January. TSPL failed to demonstrate its declared capacity on each occasion. A penalty of Rs. 162,74,72,865 was levied by Memo No. 278 dated 15 March 2017, of which Rs. 74,27,27,159 was deducted from pending bills.
At TSPL's instance, the Punjab and Haryana High Court directed the matter first to the Commercial and Metering Committee, then to the State Grid Code Review Committee, and finally to the Punjab State Electricity Regulatory Commission (SERC). The SERC affirmed the PSLDC's findings of misdeclaration on the four January 2017 dates but rejected the finding for August 2015. APTEL reversed the SERC's order entirely and directed refund of the penalty amounts. PSPCL and PSLDC appealed to the Supreme Court.
The Three-Way Distinction: Gaming, Deviation, and Demonstration
The central question before the Court was whether a failure to demonstrate declared capacity requires a finding of deliberate intent and illegal enrichment, the ingredients of “gaming” or whether it is a strict civil liability.
The Court identified four distinct categories of breach under the SG Code: over-injection and under-injection covered by UI Regulations; deviation reckoned by the DSM Regulations; gaming under Regulation 11.3.4 read with Regulations 11.3.12 and 11.3.20; and demonstration of declared capability under Regulation 11.3.4 read with Regulation 11.3.13 and Regulation 11.5(xi).
Gaming is defined in the SG Code as an intentional misdeclaration of a parameter related to a commercial mechanism in order to make an undue commercial gain. The Court agreed with TSPL that gaming requires mens rea coupled with illegal enrichment, and that any allegation of gaming must be preceded by a notice, followed by an inquiry affording a reasonable opportunity to the generating station, in full compliance with the principles of natural justice.
Demonstration of declared capability, however, is governed by Regulation 11.3.13 alone. The Court held that this is a stand-alone provision with its own penalty regime. It does not require any finding of deliberate intent or motive to profiteer. The obligation flows from the contract itself, a civil obligation and a default in demonstrating declared capability attracts penalty without anything more.
The Court found that the SERC had itself erred by treating the demonstration notice as an allegation of gaming and importing the requirement of “intention and a motive to make money” into Regulation 11.3.13. Despite that error, the SERC had correctly upheld the penalty. APTEL compounded the error by relying on that flawed reasoning to set the penalty aside entirely.
The Fourth Time Block and the Ramp Rate
A secondary dispute concerned the time within which TSPL was required to demonstrate its declared capacity after receiving a demonstration notice. TSPL argued that Regulation 11.3.13 specifies no time limit, that the notices themselves did not specify a time frame, and that demonstration at any point during the same day should suffice. APTEL had accepted this argument.
The Court rejected it. Regulation 11.5(xi) of the SG Code provides that where the PSLDC revises schedules in the interest of better system operation, the revised schedule becomes effective from the fourth time block, counting the time block in which the revised schedule is issued as the first. Each time block is 15 minutes in duration.
The Court held that this provision governs demonstration of declared capability as well. Demonstration is a measure of ensuring that the SGS has the ability to generate the capacity declared on a real-time basis. The response must materialise within four time blocks. APTEL's finding that Regulation 11.5(xi) applies only to revision of schedules was rejected as incorrect.
On the ramp rate, TSPL had declared a ramp-up/ramp-down rate of 1% per minute. The Court found that this figure appears under the nominal heading of “Governor Action” in the SG Code and is a recommended rate for changing governor settings under Regulation 5.3.8. It is not applicable to the demonstration of declared capability under Regulation 11.3.13. The fourth time block standard, not the ramp rate, governs demonstration.
Reading the TPDDL Order Correctly
APTEL had relied heavily on the CERC's order in Tata Power Delhi Distribution Limited v. Pragati Power Corporation Limited (Petition No. 199/MP/2019) to hold that misdeclaration can be found only when the generating station lacks adequate coal stock or when the plant is under shutdown or repair due to faulty machinery.
The Supreme Court found this reading to be incorrect. In TPDDL, the CERC had observed in paragraph 22 that availability is primarily declared based on fuel availability and plant machinery. That was an observation about the perceivable grounds on which capacity declarations are made not a holding that these are the only circumstances in which misdeclaration can be alleged. In that case, the SLDC had itself verified and confirmed that choking of filters did not amount to misdeclaration, and the deviation between scheduled and actual generation was addressed under the DSM Regulations.
The Court held that misdeclaration can also occur when, despite adequate coal and a functioning plant, a generator declares higher capability with an intention to profiteer which is gaming. Separately, a higher capability could be declared despite non-availability of coal or plant shutdown, the veracity of which can be verified by demanding a demonstration. The two situations are distinct and call for different regulatory responses.
The Strict Liability Principle and Dharamendra Textile Processors
The appellants had relied on Union of India v. Dharamendra Textile Processors, (2008) 13 SCC 369, to distinguish a penalty arising from civil liability from one arising in criminal liability, arguing that mens rea is absent in the former.
The Court applied this principle directly. Dharamendra Textile Processors had approved the dictum in Chairman, SEBI v. Sri Ram Mutual Fund and Anr., (2006) 5 SCC 361, that mens rea, though a sine qua non for criminal or quasi-criminal proceedings, cannot result in a straitjacket formula without looking at the language and scheme of the Act. Where a contravention — whether with guilty intent or not leads to breach of a civil obligation, the absence of mens rea is of no consequence.
The penalty under Regulation 11.3.13 is a civil liability. TSPL's obligation to generate power in accordance with its declared capability flows from the PPA a civil contract. A failure to demonstrate declared capability on notice attracts penalty without anything more, making its imposition imperative as per the statutory scheme.
Factual Analysis of the Four Days
The Court examined the spreadsheets of declared capacity, scheduled generation, actual generation and deviation for each of the four days, produced across the Bar by TSPL.
On 15 January 2017, one of three units was on reserve shutdown. TSPL revised its declared capability upward to 1841.40 MW during the day. A demonstration notice was issued in the time block of 09:30 to 09:45. The revised declared capability was not achieved on that day, much less within the fourth time block from receipt of the notice.
On 17 January 2017, only one unit was running, the second being under reserve shutdown and the third on scheduled shutdown due to a plant fault. A demonstration notice was received at 08:15 hours. On the second time block after the notice, TSPL sought a downward revision of declared capacity to 250 MW, and later to 150 MW. TSPL not only failed to demonstrate declared capacity but sought to reduce it after the demonstration notice was issued.
On 24 January 2017, the PSLDC revised the generation schedule nine times during the day. A demonstration notice was received at 14:48 hours. The declared capacity of 1650 MW was not achieved at the fourth time block or at any time thereafter.
On 31 January 2017, two demonstration notices were issued, received at 08:20 and 09:23 hours. The declared capacity was not achieved at the fourth time block from the first notice. It was achieved only at the seventh time block from the first notice, the third time block from the first notice. The Court found misdeclaration on all four days established unequivocally.
The Court also addressed the earlier APTEL decision in Punjab State Electricity Board v. CERC (Appeal No. 79 of 2007), which had found that a deviation of less than 1% is within practical limits. That case involved generating stations using both gas and liquid fuel, where the allegation was substitution of fuel to earn excess variable charges. The 1% finding was specific to the gross calorific value of gas received on a day-to-day basis and was wholly inapplicable to the present facts.
Order
The Court set aside the order of APTEL and restored the order of the SERC. It modified the restored order to the extent of removing two findings of the SERC: first, that Regulation 11.3.13 provides the procedure to deal with gaming under Regulations 11.3.4 and 11.3.12 (which the Court found to be distinct misdemeanours); and second, that deliberate intention and motive to make money are necessary ingredients for imposing penalty under Regulation 11.3.13 (which the Court found to be incorrect).
The Court directed that the consequences of the reversal including affirmation of the penalty imposed and any resultant interest liability shall necessarily follow. Any surcharge paid on bills solely because of deductions made of the penalty imposed, based on the now-reversed APTEL order, is to be refunded to PSPCL with interest or surcharge at the same rate, since TSPL had the benefit of those amounts after the APTEL order.
Both Civil Appeal No. 7432 of 2025 and Civil Appeal No. 7436 of 2025 were allowed. Pending applications, if any, were disposed of.
