The case involves a dispute over who is liable for the entire cost of a “Bay” (a component of an electrical switching station) at the 66KV Switching Station at Urni, constructed by HPPTC Ltd..
HPPTC Ltd. is a transmission licensee responsible for executing transmission networks2. BHP Ltd. is a generating company engaged in hydroelectric projects.
An Implementation Agreement was signed in 2006 to establish the Brua Hydro Electric Project (BHEP), with a capacity initially of 05 MW, later revised to 09 MW.
The connection for BHEP was planned at Karcham but was later modified to be at Urni, allowing for a joint mode connection for three generating companies: BHEP (BHP Ltd.), Shaung, and Roura-II Hydro Power Project.
A Connection Agreement (CA) dated 04.06.2014, later revised on 02.07.2021, designated Urni as the connection point.
An Internal Tripartite Agreement (ITA) dated 27.12.2019 was entered into by all three generating companies (BHP Ltd., Respondent No.02, and Respondent No.03) to allow for proportionate sharing of charges for the cost of the Bay installed by HPPTC Ltd at Urni. BHP Ltd. was designated as the sole applicant for payment under the CA dated 02.07.20216.
HPPTC’s Demand: HPPTC Ltd. raised a demand of INR 3,42,85,447 for the construction cost of the Bay.
BHP’s Stance: BHP Ltd. contended that Respondent No. 02 agreed to pay its proportionate share, but Respondent No. 03 refused to do so7. BHP Ltd. sought to deposit its proportionate share and that of Respondent No. 02, but Respondent No. 03’s share with interest subsequently. HPPTC Ltd. rejected this, stating BHP Ltd. was solely liable under the CA dated 02.07.2021.
Lower Forums:
The State Commission observed that BHP Ltd. was the lead partner of the consortium and liable for the entire connection cost, with the expectation that it would be reimbursed by the other respondents. It held that HPPTC Ltd. should not have to issue separate bills.
The Appellate Tribunal for Electricity (APTEL) reversed the State Commission’s findings16. APTEL held that Clauses 2.4 and 2.5 of the CA dated 02.07.2021 did not indicate that BHP Ltd. agreed to pay the entire Bay charges on behalf of the other respondents. APTEL concluded that HPPTC Ltd. could not unilaterally demand payment for other generating companies from BHP Ltd..
Law Involved
Electricity Act, 2003: Specifically Section 86(1)(f) and Section 111.
Himachal Pradesh Electricity Regulatory Commission (Conduct of Business) Regulations, 2005: Regulations 53, 68, and 70.
Connection Agreement (CA) dated 02.07.2021 (Revised): This was the primary contractual agreement governing the interconnection.
Clause 02 (Payment of Charges and Costs): Deals with the payment obligations for Monthly Transmission Tariff, additional costs, damages, and charges for construction of Bays.
Clause 2.4 (Agreement to pay Charges for construction of Bays): States the applicant (BHP Ltd.) shall pay charges to STU for construction of bays if required.
Clause 2.5 (Agreement to pay O&M Charges): States the applicant shall pay O&M charges to STU11.
Internal Tripartite Agreement (ITA) dated 27.12.2019: An agreement among the three generating companies for proportionate sharing of charges.
Doctrine of Privity: The principle that a contract cannot impose obligations on one who is not a party to it.
Reasoning
The Supreme Court’s reasoning focused on the interpretation of the contractual agreements, particularly the CA dated 02.07.2021 and the ITA dated 27.12.2019.
Interpretation of Agreements: The Court found that the APTEL’s interpretation of the CA dated 02.07.2021 was erroneous14. The CA explicitly designated BHP Ltd. as the sole applicant for payment of charges and costs6…. Clause 02 of the CA made it clear that all charges were to be paid by the applicant (BHP Ltd.).
ITA’s Role: The ITA dated 27.12.2019, which addressed the proportionate sharing of costs among the three generating companies, was an internal arrangement between BHP Ltd. and the other two respondents (Respondent No.02 and Respondent No.03)17. HPPTC Ltd. was not a party to the ITA.
Privity of Contract: The Supreme Court emphasized that since HPPTC Ltd. was not a party to the ITA, it cannot be bound by its terms13…. Therefore, HPPTC Ltd. cannot “seek or enforce to recover” payments from Respondent No.02 and Respondent No.03 directly. The principle of “privity to the agreement or contract cannot be, unless the context otherwise makes it apparent, made liable for any term(s) and condition(s) unrelated to it” .
BHP Ltd.’s Primary Responsibility: The Court concluded that BHP Ltd. had taken up the primary responsibility to settle the claims for all three projects with HPPTC Ltd.17. Its liability to pay the entire cost of the Bay, including metering arrangements, was established by the CA, with proportionate recovery from the other generating companies being an internal matter for BHP Ltd..
APTEL’s Error: APTEL’s decision was based on “wrong assumptions and misreading of the terms of agreement” by ignoring the basic principle of privity of contract . It failed to appreciate that the liability of BHP Ltd. to HPPTC Ltd. for the charges was explicitly stated in the CA, irrespective of the internal arrangements of the generating companies.
Holding
The Supreme Court allowed the Civil Appeal in favour of HPPTC Ltd. .
The impugned Judgment dated 17.03.2023 passed by APTEL was set aside .
The Order dated 27.12.2022 passed by the State Commission (which held BHP Ltd. solely liable to HPPTC Ltd.) was restored . This means that BHP Ltd. is liable for the entire cost of the Bay to HPPTC Ltd., and it is BHP Ltd.’s responsibility to recover proportionate shares from the other generating companies based on their internal agreement.
