AER - RBP access arrangement 2022–27 - PTRM - 2025–26 Return on debt update - March 2025

In line with our final decision on APTPPL's gas transmission network, we have updated RBP's return on debt for 2025–26. As a result of this update, the return on debt for 2025–26 is 4.58 per cent. This results in an X-factor for 2025–26 of –2.01 per cent. Holding other things constant, a positive X-factor implies a real revenue decrease and a negative X-factor implies a real revenue increase. The revised PTRM shows the updated X-factor.
