Fuel Cost Adjustment

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 April 2024 is 44.7 cents per unit.

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.
