Diesel and gas dependence
Off-grid sites burn fuel for every megawatt-hour, which drives cost and most of their emissions.
We design hybrid microgrids that use renewable power first and run generators only when they are needed.
Cleaner, steadier power for mine sites
Remote mines have long run on diesel and gas. We help miners add solar, wind and batteries to their power systems, electrify fleets and processing, and keep everything stable when the sun goes down.
Remote power, rethought
Many mine sites in Western Australia run their own power stations, far from any network. Fuel is expensive to buy and to truck in, and it is now most of a site’s emissions.
Solar, wind and batteries can carry a large share of the load, but a small islanded grid has to stay stable through every cloud, crusher start and shift change. We design those systems, plan the move to electric fleets and processing, and give operators the data to run them.
What changes on site
Four problems that come with adding renewables and electrifying a mine.
Keeping a small grid steady
In an islanded system, every cloud and every large motor start is felt across the site.
We study frequency and voltage stability and specify the batteries and controls that hold the system together.
Fleets and processing go electric
Electric haul trucks, chargers and electric processing change the size and the shape of site demand.
We plan charging, site capacity and staging so electrification keeps pace with the power that is available.
Emissions under the spotlight
Large sites face growing obligations to report and reduce emissions, and investors expect the numbers to hold up.
We bring meter, fuel and renewable data into one record for emissions and ESG reporting.
