IPART is reviewing two elements of the pricing principles in the NSW Rail Access Undertaking:

  • Remaining mine life
  • Rate of return.

Along with the other elements included in the pricing principles (such as the regulatory asset base, capital expenditure and maintenance costs) the rate of return and remaining mine life are used in determining an allowable range for rail access prices.

The NSW Rail Access Undertaking requires IPART to review the rate of return and remaining mine life every five years. The last review was completed in 2019.
