Fuel Adjustment Charge (FAC) Increases for September 2026 Due to Rising Fuel Prices

The Commonwealth Utilities Corporation (CUC) has been notified by Mobil Oil Mariana Islands that there has been an increase in the average international fuel oil prices, which affects the Fuel Adjustment Charge (FAC) for September 2026.

Pursuant to an order previously issued by the Commonwealth Public Utilities Commission, CUC is required to adjust the FAC when the “Mean of Platts Singapore” monthly pricing meets or exceeds a 4.5% differential of the average per-gallon cost of fuel used in the calculation of the FAC.

As a result, the FAC rate will increase by $0.06043 from $0.34129 per kWh to $0.40172 per kWh, effective September 1, 2026.

The FAC is one of two components that make up the CUC Electric Rate, which is strictly for fuel and fuel-related purchases. The second component is the CUC Base Rate, which has not increased since April 2014 and is used to fund operations, projects, debt services, or non-fuel-related expenses.
