TransGrid

Transgrid is the owner and operator of the high‑voltage electricity transmission network in New South Wales and the Australian Capital Territory, forming a critical part of Australia’s National Electricity Market. The company plans, builds, operates, and maintains the backbone grid that transports electricity from generators to distribution networks and directly connected large users, and provides transmission services under economic regulation.

Transgrid’s network enables reliable power supply for energy‑intensive industries, including resources and chemical manufacturing, and supports grid connections for new loads and facilities. It is developing major transmission projects—such as EnergyConnect and HumeLink—to increase interconnection, integrate large‑scale renewables, and support projects like Snowy 2.0 and designated Renewable Energy Zones. Headquartered in Sydney, Transgrid plays a central role in grid planning, system security, and capacity augmentation to meet future demand and decarbonization objectives across eastern Australia’s electricity system.
