Transgrid operates and manages the high voltage electricity transmission network in NSW and the ACT. The network connects more than three million homes, businesses and communities to a safe, reliable and secure electricity supply.
The transmission network transports electricity from generation sources such as wind, solar, hydro, gas and coal-fired power plants to large directly connected industrial customers and the distribution networks that deliver it to homes and businesses.
Transgrid’s NSW and ACT network consists of 121 substations and switching stations, 13,052 kilometres of high voltage transmission lines, 109 kilometres of underground cables and five interconnections to Queensland and Victoria. The network is instrumental to the electricity system and economy, facilitating energy trading between Australia’s eastern states.
