Large Customer Connection Standard

Ergon Energy Network and Energex are currently consulting on an update to the STNW3522 Standard for Large Customer Connections.

STNW3522 has been retitled as Standard for Large Customer Connections to reflect the terminology in the Connection Policy 2025-2030. The proposed updated standard includes updated definitions and technical requirements relevant to Large Customer connections. It also aligns with the embedded generation standards which are designed to assist with connection decisions.

We are hosting a webinar that covers the update to the standard on Thursday 5 March 2026 at 1PM.

To review a copy of the forthcoming changes or register for the webinar, please visit our page on Talking Energy.
