The Australian Energy Regulator (AER) is responsible for approving the gas distribution reference tariffs and ancillary reference tariffs for the Victorian gas distribution businesses Multinet, Envestra Victoria, Envestra Albury and SP AusNet.
For 2010, the overall average price increase for each of the businesses is limited to a weighted average CPI-X price cap. In addition a re-balancing constraint applies to each individual tariff.
The average price increase for each Victorian gas distribution business is set out below.
| Weighted average price increase | Individual tariff constraint | |
| MultiNet | 0.05% | 2.6% |
| Envestra Victoria | 0.49% | 3.0% |
| Envestra Albury | 3.15% | 5.3% |
| SP AusNet | 0.6% | 3.1% |
The tariff schedules for the gas distribution businesses can be viewed on the AER website.
