Bellevue Gold Mine Targets 90% Renewables, Aims for Net Zero Emissions
The Bellevue gold mine, located off the grid in Western Australia, is setting ambitious targets to operate with up to 90 per cent renewable energy on average. The mine has already recorded significant periods of operation without relying on fossil fuels.
Situated 40 kilometres northwest of Leinster, Bellevue boasts one of Australia’s largest off-grid hybrid energy systems, which includes 27 megawatts (MW) of solar power, 24 MW of wind energy, and a 15 MW/33 MWh battery system. This setup allows for the diesel generators to be turned off during peak renewable energy production.
World’s First Gold Mine to Achieve Net Zero Emissions
During a presentation at the Diggers and Dealers conference in Kalgoorlie, over 400 kilometres to the south, Bellevue Gold announced its intention to become the first gold mine globally to reach “net zero” emissions. The company claims it has already met this goal for its scope 1 and scope 2 emissions for the 2024/25 period, thanks to its renewable energy initiatives and the offsetting of fossil fuel usage through the acquisition of carbon assets, including savannah fire management technologies.
Renewable Energy Achievements and Future Projections
Following the recent commissioning of four 6 MW wind turbines by Zenith Energy, the mine achieved 58 hours of operation powered entirely by renewable energy in June alone. Bellevue Gold anticipates an annual renewable energy penetration of 80% to 90% now that all wind turbines are operational. The mine is projected to reach 89% renewable energy in FY26, positioning it as potentially the most renewably powered mine in Australia, whether on-grid or off-grid.
While many off-grid and remote mines aim for renewable energy usage above 50%, with some targeting between 70% and 80%, Bellevue Gold’s commitment stands out. The advancements in battery storage technology and smart control systems have enabled extended periods without diesel generator use.
Competition with Fortescue Metals
Despite Bellevue Gold’s claims, it may face competition from Fortescue Metals’ extensive Pilbara iron ore operations, which are striving to achieve “real zero” emissions by 2030. Unlike net zero, which can involve the use of carbon credits, Fortescue aims to eliminate fossil fuel use entirely across its electricity, mining operations, and transport. The company has unveiled a $4 billion initiative to deploy large electric haul trucks, excavators, and other machinery.
Consumer Demand for Sustainable Gold
Interestingly, Bellevue Gold’s commitment to net zero emissions and high renewable energy production is not solely motivated by cost savings but also by consumer demand. The jewellery sector accounts for approximately 40% of global gold demand, with ethical consumers increasingly seeking sustainably sourced gold. Bellevue is collaborating with ABC Refinery and Single Mine Origin (SMO) to cater to this market.
