The Agnew Hybrid Renewable Microgrid has officially opened, the largest currently in Australia and the first to power a mine with predominantly wind-generated electricity.

Constructed, owned, and operated by global energy producer EDL, the 56MW microgrid powers Gold Fields’ Agnew Gold Mine with an average of 50–60 per cent renewable energy, even  achieving up to 85 per cent in favourable weather conditions. 

The Agnew microgrid integrates five energy technologies to deliver high penetration renewable  energy with 99.99 per cent reliability, a non-negotiable requirement when powering the intense  industrial load demanded by mining operations: 

  • Five 110m wind turbines, each with a rotor diameter of 140m, delivering 18MW 
  • A 10,710-panel solar farm generating 4MW 
  • A 13MW/4MWh battery energy storage system 
  • Off-grid 21MW gas/diesel engine power plant 
  • Advanced microgrid control system

The Australian Renewable Energy Agency (ARENA) provided $13.5 million in funding to the  project as part of its Advancing Renewables Program, and was represented at the opening by  Shadow Minister for Planning; Lands; Heritage, Neil Thomson. 

EDL CEO, James Harman, said, “It is great to be officially opening the groundbreaking Agnew Hybrid Renewable Project with Gold Fields. 

“The project has showcased engineering excellence at every stage –  from its ambitious inception, to its skilful design and innovative integration of five energy technologies, to the complex construction and commissioning, including overcoming some major issues during the project’s final stages, caused by the pandemic and bushfires.

 “Credit must go to Gold Fields for its vision and belief that we would successfully deliver this  complex project; and credit must go also to the entire project team, including EDL and all our  contractors, who worked tirelessly to safely deliver the Agnew Hybrid Renewable Project on time and on budget. 

“Since we completed the microgrid in May 2020, and pulled the switch, it has been powering  Gold Fields’ Agnew Gold Mine with clean, reliable renewable energy. EDL’s hybrid renewable  journey has not stopped with this landmark project.” 

Gold Fields Executive Vice President Australasia, Stuart Mathews, said, “Gold Fields is enormously proud to have the opportunity to officially mark the delivery of our commitment to building a modern, sustainable hybrid renewable energy solution at the Agnew gold mine.  

“This project is a testament to what can be achieved by taking courageous decisions and  demonstrating true leadership in how we can sustainably energise our mines in remote  environments.”

Western Australia Minister for Energy, Bill Johnston, said, “Congratulations to Gold Fields and EDL on the completion of their award-winning project. 

“The partnership were recognised for their innovation and environmental excellence at Agnew winning this year’s prestigious Golden Gecko award. 

“I had the pleasure of visiting the completion of stage one of the project in 2019, when it was Australia’s first mine site to combine wind and solar power generation. 

“The McGowan Government is supportive of mining and resources companies that are leading by example and embracing renewable energy solutions. This all contributes to our target of net zero carbon emissions by 2050.”
