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.
