Case Note & Summary
The case involved multiple civil appeals concerning the jurisdiction of the Central Electricity Regulatory Commission (CERC) to revise tariffs for the National Thermal Power Corporation (NTPC) based on employee salary revisions. The appeals arose after the CERC dismissed NTPC's applications for tariff adjustments related to salary increases implemented in 2000-2001, which NTPC argued should be considered for the tariff years 1997-1998 to 1999-2000. The CERC had previously determined tariffs based on operational and financial norms, which NTPC contended did not account for the revised salary costs. The Supreme Court examined the powers of the CERC under the Electricity Act, 1998, and the associated regulations, ultimately affirming the Commission's authority to revise tariffs based on new operational data. The court noted that the CERC's jurisdiction to revise tariffs is extensive and includes the ability to consider subsequent events that impact operational costs. The court also addressed the principles of res judicata, clarifying that they do not apply to the regulatory context in which the CERC operates. The decision emphasized the need for regulatory bodies to adapt to changing circumstances in the electricity sector, ensuring that tariffs reflect actual costs incurred by generating companies. The Supreme Court upheld the Appellate Tribunal's decision to allow NTPC's claims for tariff adjustments, directing that the amounts paid in arrears be considered in future tariff calculations to minimize financial shocks to consumers.
