West Australia’s first 100% renewable-powered mine: Wind and Solar
10 to 15% of the energy for the Mt Cattlin lithium mine, 540km south of Perth in Ravensthorpe, comes from on-site solar tracking panels developed by Swan Energy, which follow arc of the sun through the sky to produce up to 15% more power than traditional fixed-axis panels. The power to close the gap for energy currently produced by coal and diesel will come from three wind turbines–1.2MW each, to take advantage of the area’s strong, consistent winds–and a 1MW solar power system.

On their website Galaxy Resources state that currently "Galaxy has 14 giant solar trackers and 2 wind turbines in operation at Mt Cattlin, which together generate 226 MWh per year of renewable energy."
The Hybrid installation is complemented by a 5MW Diesel Generator.
