Transgrid says Sydney data centers fund network upgrades to unlock up to 2 GW transmission capacity

• Transgrid set a user-pays model for Sydney transmission upgrades needed to connect new data centers to the grid.
• Network constraints block additional connections beyond signed agreements without new augmentations, despite 20 GW of large-load enquiries.
• Targeted investments could unlock up to 2 GW, including a new South Creek 500/330 kV substation.
• About 1,500 MW has been allocated under signed Western Sydney connection agreements; NSW average demand runs 7,500-10,000 MW.
• Capacity will be allocated on a first-to-sign basis, tied to commitments to fund required transmission works.
