About us

TransGrid operates and manages the high voltage electricity transmission network
in NSW and the ACT, connecting generators, distributors and major end users. 

Our network is the backbone of the National Energy Market, enabling energy trading between Australia’s three
largest states along the east coast and supporting the competitive wholesale electricity market. This allows energy consumers to gain access to the lowest cost generation available.

We strive to create value for our customers and the broader community by providing affordable, safe and reliable transmission services. Through efficient maintenance, proficient operation of assets and prudent investment in our 
network, we keep more than three million homes and businesses connected to electricity 24/7. 

We also offer a range of infrastructure and telecommunication services through Lumea, the commercial arm of TransGrid, to meet the growing needs of our customers.
