Tuppadahalli Energy India Pvt Ltd v. Karnataka Elec. Reg. Comm. & Anr.
Background
A power generating company and the Karnataka Electricity Regulatory Commission (KERC) disagreed over how to read Clause 6.5 of their Power Purchase Agreement. The company argued the clause was a one-time expenditure item, while KERC and the Appellate Tribunal for Electricity (APTEL) had both read it as an incentive/rebate payable for prompt monthly payment of tariff invoices.
Decision Breakdown
The Supreme Court noted that a separate clause (6.2) already dealt with interest on late payments, while Clause 6.5(v) was a distinct rebate tied to prompt payment of each monthly invoice, supporting the regulators' reading. Since KERC and APTEL had both taken a consistent and plausible view on this contractual question, the Court held there was no "substantial question of law" of the kind needed to justify the Supreme Court exercising its limited appellate power under Section 125 of the Electricity Act, 2003. The appeals were accordingly dismissed.
Lesson Learnt
The Supreme Court's special appellate jurisdiction over electricity regulatory decisions is reserved for genuine legal questions, not for re-litigating a reasonable contractual interpretation that two expert bodies have already agreed on.
