Tariff 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 [2]

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
