Case Note & Summary

The Supreme Court considered an appeal challenging the judgment and order dated 30th June 2021 passed by the Appellate Tribunal for Electricity, which had dismissed the appeal filed by Uttar Haryana Bijli Vitran Nigam Limited and Dakshin Haryana Bijli Vitran Nigam Ltd. and maintained the order dated 13th June 2019 passed by the Central Electricity Regulatory Commission. The dispute arose from Power Purchase Agreements dated 7th August 2008 entered into between the Haryana Utilities and Adani Power (Mundra) Limited for 1424 MW capacity, following a tariff-based competitive bidding process under Section 63 of the Electricity Act, 2003. Adani Power had filed a petition seeking tariff increase on various grounds, leading to CERC orders in 2013 and 2014, which were challenged before APTEL and eventually reached the Supreme Court. The court examined whether APTEL and CERC correctly interpreted the PPA provisions and statutory documents. The appellants challenged the dismissal of their appeal, while the respondents supported the regulatory decisions. The court analyzed the legal framework, particularly referencing the Energy Watchdog v. Central Electricity Regulatory Commission case decided on 11th April 2017, which established that statutory documents issued under Section 3 of the Electricity Act have the force of law and must guide PPA interpretation. The court also considered Clause 13.2 of the PPA regarding change in law consequences, emphasizing the principle of restoring the affected party to its original economic position through tariff adjustments. After reviewing the reasoning of APTEL and CERC, the Supreme Court found no error in their decisions and upheld the dismissal of the appeal, maintaining the regulatory orders. The court concluded that the statutory documents and PPA provisions were properly applied, and no grounds existed to interfere with the lower tribunals' findings.
