Case Note & Summary
The case involved five civil appeals arising from a common order of the Appellate Tribunal for Electricity regarding tariff determination under the Electricity Act, 2003. M/s NTPC Ltd., a power generating company, challenged the Tribunal's decision that awarded interest on differential amounts to the Electricity Boards while denying their claim for interest under Section 62(6). The Central Commission had determined tariffs for power supplied by NTPC, which were lower than previously charged, leading to excess amounts collected by NTPC. The Electricity Boards sought refunds and interest on these amounts, which the Tribunal initially rejected under Section 62(6) but later awarded based on principles of justice and equity. The Supreme Court examined the legal framework, including the historical context of tariff determination and the provisions of the Electricity Act, 2003. It noted that the Tribunal's award of interest was not supported by the statutory provisions and that the claim for interest could not be justified under equity principles, as the tariffs charged were in accordance with existing notifications. The Court ultimately allowed NTPC's appeals and dismissed those of the Electricity Boards, stating that the Tribunal erred in granting interest based on equity (Paras 1-31).
