TransGrid is the owner, operator and manager of the NSW high voltage network connecting generators, distributors and major end users in NSW and the ACT.
The network is interconnected to Queensland and Victoria, providing a strong electricity system that makes interstate energy trading possible.
The NSW transmission system is the heart of the National Electricity Market and serves the largest state in the market.
Electricity is generated at power stations then transmitted by our network through 12,656 kilometres of high voltage transmission lines and underground cables, along with 91 substations. The electricity is finally delivered to homes, factories and businesses by electricity distributors such as AusGrid, Essential Energy and Endeavour Energy.
We operate the transmission network, using the latest control and monitoring equipment to guarantee the highest level of availability and reliability of our high voltage system.
