About the hybrid renewable microgrid

The Agnew Hybrid Renewable Project has delivered Australia’s largest hybrid renewable energy microgrid—the first in the country to utilise wind generation on a large scale at a mine site.

EDL delivered this innovative hybrid renewable energy system under a 10-year agreement with Gold Fields. The Australian Renewable Energy Agency (ARENA) provided the project with $13.5 million in funding under ARENA’s Advancing Renewables Program.

The microgrid at Agnew comprises four key components managed by an advanced control system:
• 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 system
• off-grid 21MW gas/diesel engine power plant.
