The CMDs of AP-DISCOMs on Thursday said that the normative availability of energy for the generators under Power Purchase Agreements (PPAs) was 3,289.30 Million Units (MU) between December 17, 2020 and January 15, 2021. However, the actual energy availability declared for supply was 2,470.79 MU.
Responding to a letter written by the Andhra Pradesh Electricity Regulatory Commission (APERC) regarding power purchaseson Wednesday, the CMDs said the actual energy supplied by the generators was 2,253.27 MU and there was a shortfall of 819.3 MU compared to the commission’s orders. DISCOMs scouted for the cheapest power available to bridge the shortfall and saved ₹22.70 crore through market purchases.
They said that 3,289.3 MU was the availability based on the full capacity of the generating stations as per the commission’s tariff orders and it would be fully available to the DISCOMs only if the generating stations declare their ability to supply the energy, which was only 2470.79 MU.
The generators declare the energy availability on a day-ahead basis and their ability to supply it on a given day is always less than the normative availability under full capacity operating conditions.
