Sub-transmission lines The AER requires reporting against sub-transmission as one segment group. The following sections discuss the disaggregation and composition of each network segment of this segment group. Definition and reasoning for composition Energex disaggregated the network group into 24 unique network segments. The segments were disaggregated based on the following four parameters: Operating voltage Network topology Overhead and underground construction Demand growth Operating voltage Energex has disaggregated sub-transmission lines based on the following voltage categories: 110 & 132 kV 33 kV The voltage of assets has a material impact on the augmentation unit cost and capacity factors required by the Augex model.
