Australia’s landmark hybrid renewable energy microgrid complemented by thermal power generation from Cummins Power Generation

With an installed capacity of 56MW, the Agnew Hybrid Renewable Power Station became Australia’s largest hybrid renewable energy microgrid – and the first to utilize wind generation at a mine. The energy produced is equivalent to powering 11,500 homes and will abate 46,400 tonnes of carbon dioxide in the first year alone. 

“The renewable energy technologies of EDL’s Agnew Hybrid Renewable Power Station are complemented by thermal generation from Cummins gas and diesel generators,” said Jason Dickfos, EDL Head of Growth. “We’re pleased to be working with Cummins to deliver this landmark project, which will provide the Agnew Gold Mine with more than 50% renewable energy over the long term, without compromising power quality or reliability.” 

The hybrid renewable energy solution at the Gold Fields mine in Western Australia consist of a new off-grid 23MW power station incorporating gas, photovoltaic solar and diesel power generation, followed by 18MW wind generation, a 13MW battery and an advanced microgrid control system. A crucial requirement was that the generators had to provide continuous, reliable power at temperatures up to 45°C. The Cummins QSV91G gas generator model was selected due to its ability to operate in high ambient conditions, in addition to providing high impact step loads and fast ramp rates while maintaining power quality, while the Cummins QSK60 diesel units provide additional power during peak periods of demand and have black start capabilities in the event of a power outage.
