TasNetworks Distribution 2024-29 - Final decision - PTRM - 2026-27 Return on debt update - March 2026

In line with our final decision on TasNetworks' electricity distribution and transmission networks, we have updated TasNetworks' return on debt for 2026–27. As a result of this update, the return on debt for 2026–27 is 4.69 per cent. This results in an X-factor for 2026–27 of –9.13 per cent and –3.16 per cent for its distribution and transmission networks respectively. 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 PTRMs show the updated X-factors.
