200/2015Presentation Outline•Remote mine microgrids with renewable power•Raglan Mine #2 Wind-storage Pilot Project –Overview–Energy Storage–Microgrid Controls•Conclusion
300/2015Top 100 Exploration and Deposit Appraisal Projects in Canada Vs. Wind Resource DataMost new mine sites are remote and off-gridSource: Natural Resources Canada
400/2015Business Case for Renewable PowerRemote Mining Energy Cost: With Diesel Gensets–Energy represents 20-30% of mining project CAPEX–Energy represents >25% of OPEX, 30+ cents/kWhWith Renewable Power –Cost of electricity: 15 to 22 cents/kWh (with good resource)–Price certainty for 20 to 25 yearsInvestment Needed for Renewable Power – CAPEX –2.5 M$ to 4.0M$ per Installed MW–Typical return on Investment around 7 years
500/2015Glencore Raglan Mine • Located ~2000 km North of Toronto• Accessible only by sea or air• Several mines spread of a 70 km area with legacy distributed diesel generation• Good wind resourceCanadaTorontoMine
