Delivering Queensland’s First 132kV Substation

To cater for the expanding industrial development and port facilities to the north of Gladstone, Ergon Energy decided to establish a major bulk supply substation to be supplied directly from the adjacent Gladstone Power Station.

We designed both substations in parallel with staged documentation to meet the tight project schedule and installation methodology, delivering 132/66kV infrastructure and 2 × 80MVA transformers to secure long-term power supply for Gladstone’s industrial growth.

Ergon Energy is a major electricity distributor in Queensland, supplying power to regional and remote communities as well as supporting large-scale industrial developments.

For this project, Ergon Energy:

  • Commissioned its first 132kV substation in Queensland to meet the growing demand in Gladstone.
  • Required a bulk supply substation directly connected to the Gladstone Power Station.
  • Needed to cater for the expanding port and industrial facilities to the north of Gladstone.
  • Ensured long-term growth capacity by also supplying the new Port Curtis 66/11kV substation adjacent to the Gladstone Ports Corporation.

This project marked a significant milestone for Ergon Energy, delivering both reliable power infrastructure and the capacity to support Gladstone’s ongoing industrial and port expansion.

The Gladstone North 132kV Bulk Supply Substation project successfully delivered Ergon Energy’s first 132kV substation in Queensland, marking a significant step forward in supporting the region’s expanding industrial development and port facilities.

By directly integrating with the Gladstone Power Station, the substation provided a reliable and scalable power supply to meet the increasing demands of local industry. The design also enabled future growth, with outgoing bays supplying the Port Curtis 66/11kV substation to support the Gladstone Ports Corporation’s expansion plans.

Through careful staging of design and documentation, the project was delivered on a tight schedule while maintaining quality and reliability standards. In the long run, this work ensured greater energy security, capacity for industrial growth, and strengthened infrastructure for the region, helping position Gladstone as a hub for continued industrial and port development.
