ABSTRACT
Mining operations require a secure energy sources(s) to maintain their operation and many around the world typically resort to expensive diesel generated power, with fuel operating costs alone varying from $300/MWh in West Africa to over $800/MWh in the Canadian Arctic. Renewable energy solutions such as small hydro, wind and solar offer significant cost saving opportunities for these mines, and in addition help the miners attain their “Social License” to operate. If these mines have a shorter operating life (i.e. 10-15 years), the renewable energy infrastructure can provide a “Legacy Asset” for the local community and/or a longer-term revenue stream for the mine that typically needs to monitor the decommissioned mine and waste management facilities for decades after production has  eased. With a short pay-back term, renewables also offer opportunities to lower operating costs, mine lower grade material and extend the life of mine. This presentation is a practical view on renewables for two mine case histories located in Africa and in the South of the United States of America.
