Australia’s Largest Off-Grid Hybrid Renewables Power System Progress Update
Progress is well underway on the development of what could potentially become Australia’s most extensive off-grid hybrid renewables power system. The innovative project, spearheaded by renewable microgrid specialist Pacific Energy, involves the integration of 24MW of solar, 24MW of wind, and a 13MW battery energy storage system into the existing power infrastructure at the Tropicana Gold Mine in Western Australia.
Located approximately 330km northeast of Kalgoorlie, the project aims to significantly reduce the mine’s reliance on fossil fuels by up to 96%, marking a substantial step towards sustainable energy practices.
Key Project Milestones Achieved
In a recent update, Pacific Energy announced the successful completion of several crucial project milestones. These include the construction of wind turbine footings, transportation of wind turbine components to the site, and the activation of two transformers and a switchroom.
The focus has now shifted towards upcoming milestones, such as the energisation of the battery energy storage system (BESS) and the solar farm in the following weeks.
Impressive Scale and Impact
Upon completion, the combined capacity of 61MW from solar, wind, and battery sources will elevate the microgrid’s total output to 115MW. This significant expansion not only positions it as the largest hybrid investment within Pacific Energy’s portfolio but also as the most extensive islanded hybrid power system in Australia.
The integration of Pacific Energy’s advanced control system will enable the seamless optimisation of renewable energy inputs and storage technologies, facilitating prolonged periods of operation without the need for hydrocarbons.
Environmental Benefits and Reduction in Carbon Emissions
For the Tropicana Gold Mine’s operators, Anglogold Ashanti and Regis Resources, the introduction of solar and wind energy sources will lead to a substantial reduction in diesel and gas consumption by 96% and 50%, respectively. This transition is projected to result in a significant decrease in carbon emissions, estimated at an average of 65,000 tonnes annually.
The commitment and dedication of the specialised teams involved in the project have been instrumental in achieving these initial milestones, driving the clean energy transition forward and garnering commendation for their efforts.
