Main Constituents of APEPDCL Power TariffMaximum Demand (MD)Contracted MD (CMD)Recorded MD (RMD)Billing Demand (BD)

Gross Energy in kVAhElectricity Duty Charges Fuel Surcharge Adjustment (FSA)Other Charges

For Definitions see Appendix.

Salient FeaturesEnergy Consumption computation based on kVAh in place of kWH.As the kVAh is vector sum of kWH and kVARh, it represents Total Energy consumption.kVAh based energy billing encourages consumers to consume at possible higher power factor.Clause on surcharge due to low power factor removed.

APEPDCL Power TariffENERGY CHARGESActual Colony Consumption @ Rs.4.50 per kVAh unit85 % balance Energy @ Rs.3.97 per kVAh unit towards industrial load15 % balance Energy @ Rs.5.67 per kVAh unit towards lights & fan load in factory

TOD tariff (from 6 pm to 10 pm) : additional @ Rs. 1.00 per kVAh unit

APEPDCL Power TariffElectricity Duty :As per provisions of AP Electricity Duty ActAt presentElectricity Duty is @ 6 paise per kVAh on billed energy import.

APEPDCL Power TariffFuel Surcharge Adjustment ( FSA ) orFuel Cost Adjustment (FCA)To adjust the increase / decrease fuel expenses over a base reference value.

As notified by APERC commission from time to time

Applicable to all categories except agriculture

AppendixMaximum Demand, MDThe maximum demand of supply of electricity to a customer during a month shall be 4 times the largest number of kilo-Volt-Ampere-Hours(kVAh) delivered at the point of supply to the consumer during any consecutive 15 minutes in the month for the consumers having contracted demand above 4000 kVA(VSPs contracted demand is 135 000 kVA).

Billing Demand, BDThe Billing Demand shall be the maximum demand recorded during the month or 80% of the contracted demand whichever is higher(Minimum Billing Demand for VSP is 1 08 000 kVA).

Recorded Maximum Demand, RMDThe RMD shall be the maximum demand recorded during the month.

Fuel Surcharge Adjustment, FSAFSA is based on variance in the average fuel input cost for generating electricity by all the generating stations. It is applicable as per the Regulations notified by the Commission from time to time.
