A gold mine that lacked access to the grid had been powering their operations for the past couple of years with just two generators. They were right next to native lands, meaning their footprint had to be small and their expansion plans modest; but they were struggling to keep up with the output of other mines.

What’s more, they were about to hit emission compliance issues, which meant they had to find an alternative power source quickly. Their choices were limited. They could spend a lot of money to upgrade, wait for the grid to reach them, or shut down altogether. We knew we could come up with a better option.
