Days: the number of days in the consumption period
kWh: kilowatt-hours consumed during the consumption period
SVG: the Single Variable Charge
cosφ: The Customer's average power factor during the Consumption Period. Where cosφ =[1/(1/(1+(Inactive/Active)2)]% Where no reactive power is measured, take: cosφ =1.
