Building a reliable clean energy future

Reliable electricity is what keeps our homes, hospitals and businesses running every day. With EnergyConnect, we’re taking a big step towards securing that reliability, while opening the way for more renewable energy.

Construction and initial energisation is complete for EnergyConnect – Australia’s largest energy transmission project. Asset commissioning works are progressing ahead of inter-networking testing and integration into the National Electricity Market (NEM) by the end of 2026.

Stretching 900km across New South Wales, Victoria and South Australia, it has connected the three state grids for the very first time. That means:

  • Greater security of supply – keeping communities powered, even as energy demand changes.

  • Room for renewables – creating pathways for new wind, solar and other clean energy sources to plug into the grid as coal-fired plants close.

  • A stronger national network – enabling states to share energy when and where it’s needed most.

As a Critical State Significant Infrastructure (CSSI) project, EnergyConnect is central to the Australian Energy Market Operator’s plan for a more sustainable energy system.

Over the life of the project, Transgrid and our delivery partner have worked closely with communities, landholders and stakeholders to carefully plan and manage impacts to the surrounding areas. EnergyConnect isn't just new infrastructure, it’s a foundation for a cleaner, more reliable energy future.
