Case Note & Summary
The dispute arose from an appeal filed by Maharashtra State Electricity Distribution Company Limited against the Appellate Tribunal for Electricity's dismissal of its appeal regarding Late Payment Surcharge (LPS) calculations under Power Purchase Agreements with various power generating companies. The Appellant contended that the introduction of the Base Rate and Marginal Cost of Funds Based Lending Rate systems by the Reserve Bank of India constituted a change in law, which should affect the LPS calculations. The Appellant, incorporated under the Companies Act, 1956, is a distribution licensee responsible for supplying electricity across Maharashtra. The Power Purchase Agreements executed with the generating companies included provisions for LPS based on the Prime Lending Rate. The Appellant argued that the shift to the Base Rate and MCLR systems invalidated the previous methodology for calculating LPS. The court considered several substantial questions of law, including whether the notifications from the Reserve Bank of India constituted a change in law and whether LPS could be awarded without evidence of actual loss. The court analyzed the definitions of 'Change in Law' within the agreements and the implications of the Reserve Bank's notifications. Ultimately, the court held that the LPS should be calculated based on the current Base Rate or MCLR to prevent unjust enrichment of the power generators, emphasizing that LPS is compensatory in nature and should reflect actual borrowing costs. The appeal was dismissed, affirming the APTEL's decision.
