‘DISCOMs saved ₹22.70 cr. on power purchase’
The CMDs of AP-DISCOMs on Thursday stated that the normative availability of power for the turbines beneath Power Purchase Agreements (PPAs) was 3,289.30 Million Units (MU) between December 17, 2020 and January 15, 2021. However, the precise power availability declared for provide was 2,470.79 MU.
Responding to a letter written by the Andhra Pradesh Electricity Regulatory Commission (APERC) concerning power purchaseson Wednesday, the CMDs stated the precise power provided by the turbines was 2,253.27 MU and there was a shortfall of 819.3 MU in comparison with the fee’s orders. DISCOMs scouted for the most affordable power accessible to bridge the shortfall and saved ₹22.70 crore by means of market purchases.
They stated that 3,289.3 MU was the supply primarily based on the total capability of the producing stations as per the fee’s tariff orders and it will be absolutely accessible to the DISCOMs provided that the producing stations declare their means to produce the power, which was solely 2470.79 MU.
The turbines declare the power availability on a day-ahead foundation and their means to produce it on a given day is at all times lower than the normative availability beneath full capability working circumstances. The precise power declared by the turbines relies upon on machine upkeep wants and gas availability.
The power procurement plan for the following day is finalised by the State Load Dispatch Centre on the idea of the power vegetation’ declaration of the power availability.
The power availability declared on a day-ahead foundation is at all times lower than or equal to the normative availability as per the PPAs. The turbines forgo fastened prices for the power not made accessible.
Further, the CMDs stated the typical worth of market purchases for the above interval was ₹3.38 per kWh (excluding ₹0.19 /kWh AP TRANSCO fees that are refunded). The common worth of alternate power accessible throughout the identical interval from the authorized sources was ₹3.68 per kWh (excluding Transco fees). Thus, there was a saving of ₹0.30 per kWh.
The APERC must have thought of real-time availability as declared by the authorized sources. Instead, it factored within the normative authorized availability given within the retail provide tariff order. The fee has thus erroneously calculated the loss in comparison with power from power vegetation which was unavailable at the moment.
