Surcharge Calculations (September 2019)

The Fuel Adjustment Factor (Surcharge) Calculations:

Formula:      FCAF = C x (A – B)
D

where,     FCAF = The Fuel Cost Adjustment Factor (Fuel Surcharge)
A = Current Month’s Average Fuel Price (EC$/IG)
B = Average Fuel Price at Base Tariff (EC$/IG)
C = Current Month’s Fuel Usage
D = Current Month’s Electricity Production (kWh)

Fuel Cost Adjustment Factor for August 2019:

A = Average Fuel Price for August$6.90 ($/IG)
B = Fuel Base Price$2.43 ($/IG)
C = Fuel Used for August304,817 (IG)
D = Electricity Production for August5,161,152 kWh

FCAF (Surcharge) =     304,817 x 4.47 ($6.90 – 2.43)
                                                    5,161,152

COMMERCIAL/DOMESTIC = $0.26/kWh
