Hunter Power Plant

Project completion Ongoing
Location Kurri Kurri, NSW
Sectors Energy and renewables, Pumped hydro and gas

The $600 million Hunter Power Project, located in Kurri Kurri, NSW, aims to bridge the gap in electricity demand and ensure a secure electricity supply post-retirement of the Liddell Power Station in Muswellbrook.

The gas power plant facility, expected to have a nominal capacity of approximately 660 megawatts (MW) under ISO conditions, will be powered by two heavy-duty 'F Class' open cycle gas turbines (OCGT).

Symal's scope of works included various tasks:

  • Formwork, reinforcement, and pouring (FRP) of over 11,000m3 of complex concrete structural elements

  • Installation of approximately 2km stormwater services

  • Supply and installation of roughly 1.9km of potable water and sewer services

  • Supply and installation of about 1.7km of fire water services

  • Construction of all access roads, crane pads, and carparks

By providing firmed energy, The Hunter Power Project is expected to support an estimated 1.5 to 2GW of renewables, equivalent to 160,000 household solar installations. Given the project's scale, intricate coordination of trades and services has been vital, especially as mechanical works commenced concurrently with civil works.

Symal have played a pivotal role, constructing two monolithic 1200m3 structures and installing over 150 x 900mm diameter CFA piles up to 25m in depth.
