Energy poses several challenges for mining companies in Africa. A recent survey reveals, however, that costs are the dominant consideration for a mine in its planning for energy.
In the survey, 43% of mining companies said they would adopt renewable energy if it reduced costs. Another 35% of respondents supported renewables for reduced reliance on grid power, and the rest for environmental benefits.
The participants responded to the survey during a webinar titled “How to reduce reliance on grid power in Africa,” hosted by Mining Review Africa.
Energy issues for mining in Africa
While grid power is notoriously unreliable and insufficient, back-up power, usually diesel, is expensive and unfriendly to the environment.
Again, the typical mine needs a 24/7 power supply with constant voltage and stable frequency.
Moreover, it is difficult to reach energy equipment to mines located in remote and inaccessible areas.
Renewable energy the solution in Africa
Grid and renewable energy should be mutually complementary inside a formal energy plan that would reduce the mine’s overall cost of energy, said a participant in the webinar. Such a ‘hybrid’ solution had the added advantage of 24/7 availability, suggested another.
Turnkey, containerized solar systems were also a viable ‘off-grid’ solution. Mines can quickly deploy them close to where the power is needed, even in remote locations. These could also be used to set up mini-grids.
Finally, a crucial, socio-economic benefit of a renewable energy installation near a mine was its continued availability to the local population even after the end of the mine’s life cycle.
