Billing Information

Tariff Group B

Tariff group B [1] is applicable to electricity supplied by medium or low voltage, with subscribed demand not less than 69 kVA and monthly consumption not less than 10,000 kWh.

 

Standard Voltages

Low voltage (LV):  230/400 V

Medium voltage (MV): 11,000 V

 

Tariff Classes
 

B1 - MV supply and metering

B2 - MV supply with LV metering

B3 - LV supply and metering

 

Charges
 

Consumption charges under Tariff Group B are based on:

Demand - Demand in kW calculated by 0.2Pc + 0.8Pu

Pu

  • Highest measured demand in kW in a given billing period.
  • For tariff class B2, 1% of the highest measured demand is charged to recover the transformer winding loss.
  • For tariff class B3, 2% of the highest measured demand is charged to recover the transformer winding and low-voltage network losses.

Pc

  • Subscribed demand in kW.
  • Pc is updated automatically by Pu whenever Pu exceeds Pc. It is reduced to the highest Pu, whenever Pu is lower than Pc throughout a period of 12 months.

 
Active Energy

  • Energy measured in kWh.
  • For tariff class B2, 1% of the measured active energy is charged to recover the transformer winding loss.
  • For tariff class B3, 2% of the measured active energy is charged to recover the transformer winding and low-voltage network losses.

 

Reactive Energy

  • Energy measured in kvarh.
  • Only the portion of reactive energy that exceeds 60% of active energy in the same tariff period is charged.
  • For tariff classes B2 and B3, 10% of active energy in the same tariff period is charged to recover the transformer reactive energy loss.

 

Tariff Clause Adjustment

Adjustment in tariff to reflect fluctuation in energy production cost, that is fixed quarterly.

 

Government Tax

Monthly tax payable for the usage of electrical installation.

 

Tariff Periods

Full-load hours: 09:00 - 20:00

Low-load hours: 00:00 - 09:00; 20:00 - 24:00
