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 July 2019:
| A = Average Fuel Price for JUNE | $6.95 ($/IG) |
| B = Fuel Base Price | $2.43 ($/IG) |
| C = Fuel Used for JUNE | 272,597 (IG) |
| D = Electricity Production for JUNE | 4,509,806 kWh |
FCAF (Surcharge) = 272,597 x 4.52 ($6.95 – 2.43)
4,509,806
