Find out how the latest Fuel Cost Adjustment affects your electricity bill.
The Fuel Cost Adjustment (FCA) may increase or decrease your bill. It is based on the difference between forecasted fuel prices and actual fuel prices (oil, gas and coal). The Fuel Cost Adjustment is updated every month to reflect the latest fuel price changes.
Fuel Cost Adjustment from 1 May 2025 is 44.4 cents per unit.
Based on the latest Tariff Review, the annual fuel cost adjustment is 46.3 cents per unit. In May 2025, the monthly adjustment is -1.9 cent per unit. Thus, the Fuel Cost Adjustment is 44.4 cents per unit.
You may refer to the last column of the table below for calculation of the monthly adjustment.

Note:
The projected fuel cost per unit* of electricity is based on projections made in the Tariff Review.
The monthly adjustment may not be the exact sum of the last column's figures due to rounding.
The price of nuclear electricity is independent of fuel market movement and therefore no cost adjustment is required.
