Gold Fields Australia committed to reduce its carbon footprint and use renewables for at least 20% of total life-of-mine power requirements in new projects.
Two years previous, after a gas line extension was built by AngloGold Ashanti to service their mining operations in the region, Gold Fields Australia were able to use gas, a cleaner cheaper fuel source than the diesel it was using at the time to power their operations going forward.
That’s when they turned to Aggreko to deliver a 22 MW gas power station. Working closely with them to understand their needs, we delivered highly efficient bespoke modified engines that reduced their fuel costs and environmental impact.
Knowing Aggreko had recently announced the launch of microgrids-as-a-service for customers who want to leverage the benefits of a hybrid energy solution while minimising capital outlay, discussions began about how and if this could be incorporated into their current power package without compromising the micro-grid stability or reliability.
To integrate 8 MW of solar power generation, and 2MW / 1 MWh battery storage with the existing gas supply as a hybrid power station – under one contract and with no capital outlay.
This unique energy package combines solar, thermal and battery storage that’s seamlessly integrated and managed by our powerful software platform - guaranteeing full system availability and optimising their existing thermal assets life.
This new solar gas hybrid power station will meet the increased daily power needs of the entire mine of 24.2 MW, with 8 MW allocated to the Wallaby underground mine and the remaining 16.2 MW for the processing plant, associated facilities and the mine accommodation camp.
