The HP Power Transmission Corporation Ltd. v. M/S Brua Hydrowatt Pvt. Ltd.

Civil Appeal · 2025 INSC 680Decided 14 May 2025
C.A. No.-003919 of 2023
Justice Abhay S. Oka · Justice Augustine George Masih

Background

HP Power Transmission Corporation (HPPTC), the state transmission licensee in Himachal Pradesh, built a "Bay" (a switching station facility) at Urni to connect several hydroelectric generating companies, including Brua Hydrowatt's (BHP) Brua Hydro Electric Project, to the grid. A dispute arose over who must bear the entire cost of constructing this Bay. The State Electricity Regulatory Commission held BHP alone liable, based on the specific Connection Agreement it had signed with HPPTC. On appeal, the Appellate Tribunal for Electricity (APTEL) reversed this, spreading the liability to other generating companies that also benefited from the Bay, even though they were not parties to that agreement.

Decision Breakdown

The Supreme Court restored the State Commission's order, holding that APTEL erred by relying on documents and understandings outside the actual Connection Agreement to fasten liability on companies that were not signatories to it. The Court reaffirmed the basic contract law principle of privity of contract: a party who merely benefits from infrastructure, but is not bound by the agreement's express terms, cannot be made liable for costs under that agreement unless the agreement itself says so. Since the Connection Agreement explicitly bound only BHP to pay for the Bay, the Tribunal's attempt to spread the cost to other beneficiary companies was legally unsound.

Lesson Learnt

Financial liability under a contract runs with its actual signatories and explicit terms: a third party cannot be forced to share costs merely because it incidentally benefits from what the contract created, unless the contract itself makes it liable.

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.

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

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.

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.
