Table 3.3 Transmission networks in the NEM Source: AER (2017b, p. 96). The transmission network assets in all states except Victoria are government owned. In Victoria, the network is owned by the private sector TNSP. In contrast, the majority of companies that actually operate the networks the TNSPs — — are privately owned, with the TNSPs in South Australia and New South Wales leasing the assets from their respective state governments. The transmission networks and the TNSPs in Queensland and Tasmania are government owned. Interconnectors Interconnectors are the highvoltage transmission lines that transport electricity between most adjacent regions in the NEM (although not between New South Wales and South Australia). They allow electricity to be imported into a region when demand is higher than can be met by local generators, or when the price of electricity in an adjoining region is low enough to displace local supply. There are six interconnectors currently in the NEM (table 3.4). Each interconnector consists of connections to allow electricity to flow in both directions. However, as the capacity of the connections are often not symmetric, some interconnectors allow more electricity to flow in one direction than the other. There are two types of interconnectors in the NEM: regulated interconnectors unregulated interconnectors.
