Billing Demand
A billing demand is defined as the maximum 15-minute integrated demand during an On-Peak and Partial-Peak period over the monthly billing period that is measured to the nearest full kilowatt discarding the fraction of 0.5 kW.
Minimum Charge
A monthly minimum charge of any billing period shall not be less than 70% of the maximum billing demand charge for the preceding 12 months.
Power Factor Charge
For a customer with a lagging power factor, if in any monthly billing period during which the customer's maximum 15-minute reactive power demand (kilovar demand) exceeds 61.97% of his maximum 15-minute active power demand (kilowatt demand), a power factor charge of Baht 56.07 will be made on each kilovar in excess, determined to the nearest whole kilovar, discarding the fraction of 0.5 kilovar.
