Enerven has delivered the design and construction of the critical high-voltage grid connection works linking the Liddell BESS to the 330 kV Transgrid network, including a new 330k BESS Substation, 330kV transmission line and the augmentation of an existing 330kV switch bay at Liddell to facilitate the grid connectivity of the Liddell BESS.

The customer

Transgrid builds and maintains the largest electricity network in Australia, providing the backbone of the National Electricity Market while supporting the transition to a cleaner energy future.

These works were critical to enabling seamless grid integration of the Liddell Battery Energy Storage System, strengthening network reliability and system security.

The opportunity

The Liddell Battery BESS is a landmark renewable energy project constructed at the site of the former Liddell Power Station. Enerven’s role for Transgrid encompasses the design and construction of critical infrastructure to connect the battery to the National Electricity Market (NEM). This includes the construction of a 330/33kV battery substation, a ~450-meter 330kV overhead transmission line, and an extension to the existing 330kV switchyard. These works were critical to enabling seamless grid integration of the Liddell Battery Energy Storage System, strengthening network reliability and system security.

The solution

Key specifications delivered by Enerven:

– A new 330kV BESS substation with 2 x 320 MVA transformers
– A 330kV transmission line
– Extension of an existing 330kV switching station.

 

We successfully delivered the design and construction of a 330kV BESS connection, supporting our client Transgrid. The energisation was delivered just five months from earthworks completion. This project reinforces our proven capability in high-voltage infrastructure and complex program delivery, contributing to the successful deployment of one of NSW’s key grid-scale batteries.
