Surcharge Calculations (May 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 MAY 2019:

A = Average Fuel Price for APR$7.37 ($/IG)
B = Fuel Base Price$2.43 ($/IG)
C = Fuel Used for APR300,813 (IG)
D = Electricity Production for APR4,855,544 kWh

FCAF (Surcharge) =     300,813 x 4.94 ($7.37- 2.43)
                                                    4,855,544

COMMERCIAL/DOMESTIC = $0.31/kWh
