Tariff Group B¹ is available to custumers supplied by medium or low voltage, with subscribed demand not less than 69 kVA and monthly consumption not less than 10,000 kWh.

B1 - MV supply and metering
B2 - MV supply and LV metering
B3 - LV supply and metering

Consumption charges under the tariff group B are based on :

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

• For tariff class B2, 1% of the highest 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 loss. 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 Adjustment² - Adjustment in tariff to reflect fluctuation in energy production cost, that is fixed quarterly.

Government Tax - Monthly tax payable for the usage of electrical installions.

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

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

• Arrange to consume energy during low-load hours, as much as possible.
• Reduce reactive energy consumption by installing compensation equipment like capacitor bank.
• Reduce the simultaneous usage of electrical equipment to decrease demand charges.
