Case Note & Summary
The Supreme Court addressed 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. The dispute arose after the Reserve Bank of India introduced the Base Rate system in 2010 and the Marginal Cost of Funds Based Lending Rate (MCLR) in 2016, which the Appellant contended constituted a change in law affecting the LPS. The Appellant argued that the LPS should be recalculated based on these new methodologies, while the Respondents maintained that the existing agreements stipulated the use of the Prime Lending Rate (PLR) for such calculations. The court examined the definitions of 'Change in Law' within the agreements and concluded that the notifications from the Reserve Bank did not qualify as a change in law under the agreements. It emphasized that the LPS is compensatory and should not lead to unjust enrichment of the power generators. The court ultimately upheld the APTEL's decision, affirming that the LPS should continue to be calculated based on the PLR as defined in the agreements, without accommodating the new lending rate systems introduced by the Reserve Bank. The court's ruling underscored the importance of adhering to the contractual definitions and the need for evidence of actual loss to justify any claims for LPS.
