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.
