Bridging the power gap for off-grid mines

Mining companies are under great financial pressure as a result of fluctuating demand and uncertainty around commodity prices, so the need to improve efficiency across all operational aspects of a mine site is mission critical. Reducing costs and maximising production are key issues directly impacted by a firm’s energy choices.

Grid connection is not always available as mining companies are forced to push new frontiers of exploration due to scarce resources. To reach those resources which remain, mines are increasingly being established in off-grid locations and their lifecycle is decreasing, meaning it is no longer always financially viable to build permanent power infrastructures to service the mine.

Instead, remote mines are now utilising scalable microgrids that can evolve with the lifecycle, improving flexibility and efficiency. These microgrids also offer an independence from the grid that can often result in a cost-effective solution that doesn’t compromise on reliability. Whether it’s a thermal, renewable or a hybrid, a mine’s power strategy needs to address capacity needs and how this is likely to change.
