In a recent order, CERC has revised National APPC (Average Power Purchase Cost) for wind or solar generators that are regional entities and selling power under Open Access, which is not accounted for RPO (Renewable Purchase Obligation) compliance of obligated entities, and for captive power plants where PPAs do not exist, settlement shall be done at APPC determined at the national level. CERC has calculated APPC by taking into account of APPC of all states , UTs for FY 2020-2021 weighted by volume of conventional power purchased by the respective state/UT for FY2020-2021. The total cost of power purchase considered for calculating the APPC excluded the cost of generation or procurement from renewable energy sources and transmission charges. The exclusion is in line with the determination of APPC to calculate the average cost of power from conventional sources.
