Electricity is generated at power stations then transmitted by TransGrid through a 12,500km network of high voltage transmission lines and substations. The electricity is finally delivered to homes, factories and businesses by electricity distributors such as Integral Energy, Energy Australia and Country Energy.
TransGrid operates the transmission network, using state-of-the-art control and monitoring equipment to ensure the highest level of availability and reliability of our high voltage system.
