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 March 2019:
| A = Average Fuel Price for FEB | $6.93 ($/IG) |
| B = Fuel Base Price | $2.43 ($/IG) |
| C = Fuel Used for FEB | 269,548 (IG) |
| D = Electricity Production for FEB | 4,184,570 kWh |
FCAF (Surcharge) = 269,548 x 4.50 ($6.93- 2.43)
4,184,570
