Eastern Goldfields Power Project (KCGM -Super Pit)

Eastern Goldfields Power Project (KCGM -Super Pit)

The KCGM Project is a large-scale gold mining operation located in Kalgoorlie-Boulder, Western Australia. Zenith Energy has been contracted to deliver Australia’s largest renewable energy power solution for the mining sector, supporting the decarbonisation of one of the country’s most iconic mining operations.

Project Background

Kalgoorlie Consolidated Gold Mines (KCGM), operator of the Super Pit in Western Australia, is one of Australia’s largest gold mining operations. Zenith Energy has been contracted to deliver a renewable energy project and in a JV with Northern Star Resources a dual fuel thermal power station to support the KCGM expansion while significantly reducing its carbon intensity. The project represents a major step in the decarbonisation of large, energy-intensive mining operations. 

Renewable Integration

The renewable project integrates 256 MW of wind generation138 MW of solar photovoltaic capacity, and a 138 MW / 300 MWh battery energy storage system to deliver renewable power while managing intermittency. 

How Zenith is Leading the Sector

Zenith Energy has entered into a 25-year Power Purchase Agreement (PPA) with Northern Star Resources to design, build, own, and operate Australia’s largest renewable energy project dedicated to mining. 

This project increases Zenith’s portfolio renewable energy to 59% of its total contracted capacity, reinforcing Zenith’s leadership in large-scale renewable integration for the mining sector. 

Installed Capacity

  • Wind: 256 MW 
  • Solar PV: 138 MW 
  • Battery Energy Storage System (BESS): 138 MW / 300 MWh
  • Total Renewable Capacity: 394 MW plus 300 MWh of storage
  • In addition, 120 MW of thermal generation will be delivered under a joint venture with Northern Star to ensure system reliability and continuity of supply. 

Commercial Operation date

Commissioning is targeted for mid-2027, subject to environmental and regulatory approvals.

Contract Term

The project is underpinned by 25-year Power Purchase Agreements with Northern Star Resources. Under this long-term framework, Zenith will construct, own, and operate power solution including the associated transmission infrastructure.
