Declared capacity is strict obligation, not target: Supreme Court rules against power generator
The Supreme Court of India has restored a penalty of over Rs 162 crore imposed on Talwandi Sabo Power Limited (TSPL) for failing to demonstrate its declared generation capacity on four occasions in January 2017. The Court set aside an earlier order of the Appellate Tribunal for Electricity (APTEL), which had granted relief to the generator, and upheld the findings of the Punjab State Electricity Regulatory Commission (SERC).
A bench led by Justice K. Vinod Chandran ruled that demonstrating declared capacity under the Punjab State Grid Code is a “strict liability” obligation. The judgment clarified that regulators do not need to establish malicious intent or unlawful profit before imposing penalties for failure to demonstrate declared generation capability within the prescribed timelines.
The dispute
The dispute originated from notices issued by the Punjab State Load Despatch Centre (PSLDC) between January 15-31, 2017. PSLDC had directed TSPL to demonstrate that it could achieve the generation capacity it had declared. The generator failed to meet the declared capacity within the mandated four time-blocks of 15 minutes each, resulting in a penalty of Rs 162.75 crore. Of this amount, Rs 74.27 crore had already been adjusted from pending payments.
While SERC upheld the penalty for four days in January 2017, APTEL later reversed the order, stating that no specific time limit had been prescribed for demonstrating capacity and that small deviations should not attract punitive action. The Supreme Court disagreed with that interpretation and held that Regulation 11.3.13 of the Punjab State Grid Code creates a civil obligation with strict enforcement standards.
Key findings
The Court distinguished between “gaming,” “deviation,” and “demonstration of declared capacity,” stating that each operates under separate legal standards. According to the judgment, gaming involves intentional misdeclaration for undue profit and requires proof of intent and unlawful enrichment. Deviations relate to differences between scheduled and actual injection or drawal under Deviation Settlement Mechanism (DSM) Regulations. In contrast, failure to demonstrate declared capacity within four time-blocks attracts strict liability regardless of intent.
Referring to the Supreme Court ruling in Dharamendra Textile Processors, the bench observed that absence of mens rea is irrelevant where penalties arise from breach of a civil obligation. The Court stated that the regulatory framework allows State Load Despatch Centres (SLDCs) to verify declared capacity through real-time demonstration notices in order to protect grid discipline and commercial accountability.
Four dates examined
The judgment examined each of the four disputed dates separately. On January 15, 2017, the declared capacity was revised upward to 1841.40 MW but was not achieved despite notice being issued during the 09:30-09:45 time block. On January 17, 2017, the generator sought downward revision of capacity immediately after receiving the notice at 08:15 hours, which the Court treated as an acknowledgment of inability to demonstrate the declared level.
For January 24, 2017, the Court noted that neither the declared capacity of 1650 MW nor the scheduled generation was achieved despite multiple schedule revisions by SLDC following a notice issued at 14:48 hours. On January 31, 2017, the Court held that achieving the declared capacity after the fourth time block was insufficient, since compliance was required within the prescribed period.
Defences rejected
The Supreme Court also rejected several arguments raised by TSPL. The generator cited its operational record and “fidelity” over nine years, but the Court held that past conduct cannot override contractual and regulatory obligations. A force majeure defence was not pursued further after the bench sought specific details. The Court also rejected TSPL’s interpretation of the Central Electricity Regulatory Commission (CERC) ruling in TPDDL v. PPCL, stating that the earlier observations were illustrative and not exhaustive criteria for determining misdeclaration.
Sector impact
The ruling is expected to have wider implications for India’s power sector. The Court observed that fixed charges are linked to declared generation capability even when procurers do not schedule the full power. Distribution companies continue to bear payment obligations based on such declarations, while generators can earn incentives for annual availability exceeding 80% of declared capability. The judgment reinforces the authority of SLDCs to verify declarations through operational checks.
The Supreme Court directed that the penalty amount already adjusted from bills would not be refunded. It also allowed Punjab State Power Corporation Limited (PSPCL) to continue adjusting further amounts under protest while preserving any additional remedies available to TSPL.
The Court further clarified that failure to demonstrate declared capacity and gaming are separate violations under electricity regulations. While gaming requires proof of intent, failure to demonstrate declared capacity attracts strict liability. The clarification resolves a long-standing regulatory ambiguity that had resulted in differing interpretations by tribunals and sector regulators.
