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 Sales (kWh)
Fuel Cost Adjustment Factor for MAY 2021:
| A = Average Fuel Price for APRIL | $6.49 ($/IG) |
| B = Fuel Base Price | $1.60 ($/IG) |
| C = Fuel Used for APRIL | 255,439 (IG) |
| D = Electricity Sales for APRIL (kWh) | 4,428,598 kWh |
FCAF (Surcharge) = 255,439 x 4.89 ($6.49 – $1.60)
4,428,598
