GUJARAT URJA VIKAS NIGAM LIMITED vs TARINI INFRASTRUCTURE LTD..

The Supreme Court addressed whether the tariff fixed under a Power Purchase Agreement (PPA) is immutable and beyond review by the State Electricity Regulatory Commission under the Electricity Act, 2003. The Court held that the Regulatory Commission possesses the authority to redetermine tariffs, thereby overruling the previous stance of the Commission that denied such power. The appeals were decided in favor of the power producers, allowing for tariff reassessment based on changed circumstances.
