Punjab State Power Corporation Limited v. Talwandi Sabo Power Limited & Ors.

Civil Appeal · 2026 INSC 515Decided 20 May 2026
C.A. No.-007432 - 2025
Justice Sanjay Kumar · Justice K. Vinod Chandran

Background

Talwandi Sabo Power Limited (TSPL), a generating station supplying power to Punjab State Power Corporation Limited (PSPCL), is required under its Power Purchase Agreement to daily declare its power generation capacity, which the Punjab State Load Despatch Centre (PSLDC) uses to schedule electricity dispatch. The PSLDC found that on four days in January 2017, TSPL failed to actually demonstrate/achieve the capacity it had declared, and imposed a heavy penalty running into crores of rupees. After a series of proceedings: the State Electricity Regulatory Commission (SERC) partly upheld the misdeclaration finding, but the Appellate Tribunal for Electricity (APTEL) reversed it and deleted the penalty entirely, holding that "deliberate intention and motive to make money" needed to be shown. PSPCL and PSLDC appealed to the Supreme Court against APTEL's reversal.

Decision Breakdown

The Supreme Court examined the day-by-day generation records for each of the four disputed days in detail and found that TSPL had indeed failed to demonstrate its declared capacity after being issued "demonstration notices," in some instances even revising its declared capacity downward after being caught short. The Court held that the penalty for failing to demonstrate declared capability is a civil liability flowing from the contractual/regulatory scheme (the Grid Code), and does not require proof of criminal-style intent or "mens rea": unlike a separate provision dealing with "gaming"/profiteering, which the Court held APTEL had wrongly conflated with the demonstration-failure penalty. Finding these two to be distinct types of default under the regulations, the Court set aside APTEL's order, restored the SERC's order (which had upheld the January 2017 misdeclaration findings), and directed that any surcharge PSPCL had refunded to TSPL as a result of APTEL's now-reversed order be paid back with interest.

Lesson Learnt

In regulatory schemes like the electricity grid code, a penalty for failing to meet a declared obligation (such as declared generation capacity) can be a straightforward civil liability that applies automatically on proof of default. It need not require proving deliberate wrongdoing or profit motive unless the specific rule says so.

Radhey Shyam Gupta vs. Tata Power Delhi Distribution Limited

Both the trial court and the first appellate court had dismissed the suit, holding that the Electricity Act, 2003 gives exclusive jurisdiction over such compensation disputes to statutory bodies like the District Magistrate or Commissioner of Police rather than to civil courts, and that the plaintiff had failed to prove any actual monetary loss to justify the damages claimed. The High Court agreed on both points: even though the electricity company had indeed skipped the legally required step of getting the landowner's consent or, failing that, permission from the District Magistrate/Police Commissioner before laying its lines, the law still channels any compensation dispute exclusively to those statutory authorities, not the civil courts. Separately, the plaintiff had given no real evidence (such as how the property's value dropped, or how Rs. 50,000/month was calculated) to support his damages claim. Since no genuine "substantial question of law" was raised, the Regular Second Appeal was dismissed.

Dakschinanchal Vidyut Vitran Nigam Ltd. v. Vidut Lokpal, Uttar Pradesh and Others

The Supreme Court held that the consumer's liability to pay for additional electricity load arises only once that load is actually released to the consumer, and there was no evidence the additional 2000 KVA was ever released or consented to by the consumer, undermining the demand on merits. More decisively, relying on its earlier ruling in Assistant Engineer (D1), Ajmer Vidyut Vitran Nigam v. Rahamatullah Khan, the Court held that under Section 56(2) of the Electricity Act, 2003, charges become "first due" only when a bill is actually issued, and a demand must be raised within the statutory limitation period from when dues first became payable. Here, a demand raised for the first time in 2007 for a 1998 period, with no proof the sum had been continuously carried as recoverable arrears in interim bills, was hopelessly time-barred. The Court accordingly dismissed the appeal, upholding the quashing of the 2007 demand.

M/S Amalgam Steels and Power Ltd. v. Energy Watchdog

The Supreme Court held that this was only an appeal against an interim order in a still-pending High Court writ petition, and that its role at this stage was limited to checking whether the High Court's interim direction was so unreasonable as to be "perverse." Noting that the High Court had found something amiss in why action against the company had not been taken earlier despite a long-standing complaint, the Court held that allowing the NGO to participate in JBVNL's inquiry (even though not a party to the underlying supply agreement) was a permissible interim measure to help JBVNL gather full facts before deciding, and not something warranting interference under Article 136. The Court clarified it expressed no opinion on the merits, leaving the High Court free to fully examine the scope of third-party participation at the final hearing, and disposed of the petition.

Indian Railways v. West Bengal State Electricity Distribution Company Limited & Ors.

The Supreme Court held that Indian Railways procures electricity for its own use and consumption, making it an industrial consumer rather than a distribution licensee, and that consumers availing open access are liable to pay Cross-Subsidy Surcharge and Additional Surcharge under the Electricity Act. The Court noted that a draft Electricity (Amendment) Bill, 2025 proposed specifically to exempt Railways (along with metro rail and manufacturers) from cross-subsidy surcharges within five years, and reasoned that a proposed legislative exemption itself signals that no such exemption exists under the current law, since courts cannot read into a statute an exemption that Parliament has not yet enacted. It also held that as a Central Government entity, Railways could not "approbate and reprobate" by arguing a position contrary to what the government's own proposed amendment implied. All the appeals were dismissed, APTEL's order was upheld, and the distribution companies were directed to compute and communicate the outstanding surcharge amounts to Railways, who would get a fair opportunity to respond before final figures are settled.

Delhi Electricity Regulatory Commission v. Tata Power Delhi Distribution Limited

The Supreme Court held that tariff determination is a regulatory balancing exercise that must protect consumer interests under Section 61(d) of the Electricity Act, 2003, and that consumers cannot be made to pay for electricity they no longer receive. It held that Regulation 6.32 of the DERC Generation Tariff Regulations (which prescribes depreciation over an asset's useful life) cannot be read in isolation and must be harmonised with Regulation 4.1, which ties tariff entitlement to the period approved under the Power Purchase Agreement: here, six years ending March 2018. Since the Commission's 2017 order fixing this six-year recovery period was never challenged by TPDDL and had become final, the Court held APTEL was wrong to reopen and reconfigure that settled framework in later true-up proceedings. Answering all three legal questions against TPDDL, the Court set aside APTEL's judgment and restored the Commission's order denying further depreciation recovery.

Southern Power Distribution Company of Andhra Pradesh Limited v. Green Infra Wind Solutions Limited

The Supreme Court rejected both extremes. It held that tariff determination remains the exclusive province of the State Electricity Regulatory Commission, and this power is not taken away just because Parliament sanctioned funds for the GBI scheme. However, the Commission's own regulations require it to "take into consideration" any government incentive when fixing tariff, but this does not mean automatically deducting or passing through the GBI amount. Since the GBI was designed as a generator-focused incentive to encourage renewable investment (not a consumer subsidy), the Commission must respect and give effect to that underlying purpose rather than mechanically offsetting it against tariff. The Court dismissed the appeal, holding the GBI is meant to be paid to generators over and above the tariff.
