Supreme Court Directs Punjab And Haryana To Supply Himachal Pradesh 11,973 Million Units Of Pending Hydel Power Over Twenty Years, Finally Resolves Decades-Old Bhakra–Beas Dispute
Supreme Court Enforces 2011 Hydel-Power Decree Through Cashless Settlement, Adjusts ₹420.77 Crore Capital Liability Against Energy Arrears And Rejects Punjab’s Fresh Objections
Facts
The State of Himachal Pradesh instituted Original Suit No. 2 of 1996 under Article 131 of the Constitution against the Union of India and other governments, claiming its share of electricity generated by the Bhakra-Nangal and Beas hydroelectric projects after the reorganisation of composite Punjab in 1966. These projects involved extensive submergence of land now within Himachal Pradesh. On 27 September 2011, the Supreme Court partly decreed the suit, recognising Himachal Pradesh’s entitlement to 7.19% of the power attributable to composite Punjab under Section 78 of the Punjab Reorganisation Act, 1966. The decree translated that entitlement into project-specific shares and directed the Union to compute the consequential dues. An intergovernmental assessment filed in 2013 quantified unprovided energy through October 2011 at 13,066 million units (MU), comprising 8,523 MU from Bhakra-Nangal, 3,145 MU from Beas Unit I and 1,398 MU from Beas Unit II. Continued disagreement over valuation, capital expenditure and allocation between Punjab and Haryana prevented implementation. The judgment dated 6 November 2026 addresses execution-like implementation of the 2011 decree, not the reopening of the original entitlement.
Issues
What amount of historical energy arrears was due to Himachal Pradesh and how should it be valued; how much of the projects’ capital and loan-servicing costs should be borne by the State; whether the energy entitlement could be set off against that liability; whether settlement should occur through money or energy supply; and what apportionment and delivery schedule should finally bind Punjab and Haryana. The Court also considered whether objections raised by Punjab could reopen settled matters under the 2011 decree.
Plaintiff-State’s Submissions
Himachal Pradesh accepted the Union’s assessment of a 13,066-MU shortfall and the earlier calculation of ₹111.54 crore towards certain capital, renovation and operating costs, but disputed the rate proposed to monetise the arrears. It argued that the National Fertilizers Limited tariff was historically concessional and that the Bhakra Thermal Power Station (BTPS) rate better reflected actual inter-State electricity transactions. On that basis it advanced a monetary claim of ₹4,249.45 crore. It additionally invoked the burdens of submergence and displacement and sought reimbursement of ₹1,745 crore allegedly spent purchasing replacement electricity from the open market. It ultimately agreed in principle to the Attorney General’s later proposal for adjustment and supply of energy in kind.
Defendants’ Submissions
The Union of India, through the Attorney General, proposed a cashless framework: recognition of 13,066 MU in gross arrears; adjustment of Himachal Pradesh’s reconstructed capital-cost liability of approximately ₹420.77 crore at ₹3.85 per unit; and delivery of the residual energy by Punjab and Haryana, initially over fifteen lean seasons. Punjab objected that 1.2 lakh units supplied daily at a concessional rate had not been deducted, asserted that the net arrears should be 11,094 MU, sought valuation at a current operation-and-maintenance (O&M) rate rather than ₹3.85, and preferred thirty years for repayment. It also claimed substantially higher capital liability. Haryana disputed certain historic allocation ratios and aspects of the capital-cost data, but accepted the final settlement proposal in principle.
Analysis of the Law
Article 131 confers original jurisdiction over the specified intergovernmental dispute; Section 78 of the Punjab Reorganisation Act, 1966 governs apportionment of rights and liabilities associated with the Bhakra-Nangal and Beas Projects among the successor States. The substantive entitlement had already been judicially determined in 2011: 6.095% of total Bhakra-Nangal output, 5.752% of Beas Unit I and 2.984% of Beas Unit II, reflecting Himachal Pradesh’s allotted proportion of composite Punjab’s project interests. In 2026, the Court treated the remaining proceeding as execution-like: a final decree could not be diluted by revisiting entitlement or by using inapt modern tariff assumptions for liabilities arising decades earlier. Since the unresolved question was effective performance, the Court could prescribe a workable in-kind mechanism, including an equitable set-off against the beneficiary State’s attributable capital expenditure.
Precedent Analysis
The controlling earlier adjudication was the Supreme Court’s own decision of 27 September 2011 in State of Himachal Pradesh v. Union of India, Original Suit No. 2 of 1996. That judgment rejected the State’s separate demand for 12% free power under the later ‘Home State’ policy but recognised an enforceable statutory share under Section 78; it found the 1967 arrangements tentative and directed computation of dues rather than awarding the full amount then claimed. The present judgment does not purport to reverse those holdings or to lay down a new free-power entitlement. Instead, it translates the binding declaratory decree into an executable supply-and-adjustment schedule and disallows arguments that would re-litigate matters already settled.
Court’s Reasoning
The Court found that the Union’s settlement methodology was developed after extensive review of alternative tariffs, capital-cost formulas, energy distribution and repeated unsuccessful settlement attempts. Punjab’s proposed subtraction for the historical supply of 1.2 lakh units per day did not warrant a further reduction because the relevant variables had already been accounted for in the framework. Its attempt to convert earlier capital liabilities using the present O&M rate was rejected as an inaccurate and potentially inflated set-off: historical energy arrears could not fairly be recalculated at a tariff prevailing today. No compelling reason was given for extending delivery to thirty years, though the Court moderated the Union’s fifteen-year timetable to twenty years to ease the burden on Punjab and Haryana. It fixed gross arrears at 13,066 MU and Himachal Pradesh’s capital liability at ₹420.77 crore (recorded as ₹249.23 crore attributable to Punjab and ₹171.55 crore to Haryana). At ₹3.85 per unit, this produces a set-off of approximately 1,093 MU and leaves approximately 11,973 MU for supply. The inter se supply ratios are 58:42 for Bhakra-Nangal and 60:40 for the Beas Projects. Deliveries are to occur in the October–March lean seasons, with Himachal Pradesh paying the BBMB-determined charges applicable in the year of each tranche.
Conclusion
The Supreme Court ordered a cashless settlement and finally disposed of the suit. The gross 13,066-MU entitlement is to be discharged over twenty lean seasons, stated at 653 MU annually before adjustment; upon set-off of about 1,093 MU against the ₹420.77-crore capital liability, Punjab and Haryana must deliver the remaining approximately 11,973 MU at about 598 MU per year over twenty lean seasons. The Court rejected Punjab’s objections to the core computation, fixed the project-specific allocation ratios, and directed all stakeholders to give binding effect to the decree without further obstruction. Importantly, this is an implementation ruling, not a fresh award of ₹4,249.45 crore or ₹1,745 crore in cash, and the final relief is the specified net power supply rather than 13,066 MU on top of the capital-cost adjustment.
