Slide 5: Climate change impacts are being realised and miners have set decarbonisation deadlines
Problem Statement 1 THE NEGATIVE IMPACTS OF CLIMATE CHANGE ARE BEING REALISED AND MINING COMPANIES HAVE SET DEADLINES TO DECARBONISE THEIR OPERATIONS
Slide 6: To fully decarbonise we must also electrify our fleets
Problem Statement 2 TO FULLY DECARBONISE WE MUST ALSO ELECTRIFY OUR FLEETS SO OUR PLANS FOR RENEWABLE ENERGY PRODUCTION MUST (DOUBLE)
Slide 7: High penetration renewables present a stability risk to mine site microgrids
Problem Statement 3 HIGH PENETRATION RENEWABLES PRESENT A STABILITY RISK TO MINE SITE MICROGRIDS AND SAFETY AND PRODUCTION ARE KING
