Electricity Tariffs’ Conditions

1. Power factor charge will be collected from the customer who causes the lag of power factor. When the maximum of an average reactive power (kVAR) demand in 15 minutes in any period of time is more than 61.97% of the maximum of an average active power (kW) demand in 15 minutes in any period of time, 56.07 Baht/kVAR will be added. (If the fraction of kVAR is lower than 0.5 kVAR, it will be rounded down, and if it is equal or over 0.5 kVAR, it will be rounded up to 1 kVAR.)

2. Monthly Electricity Charge is composed of the electricity tariffs which has mentioned above, Automatic Tariff Adjustment Mechanism (Ft), and VAT.

2. The electricity tariffs which has mentioned above are not excluding a Value Added Tax (VAT).

THE ABOVE ELECTRICITY TARIFFS ARE EFFECTIVE FROM THE BILLING MONTH OF NOVEMBER 2018 ONWARDS.
