As this week’s feature shows, the energy and greenhouse gas emissions savings that can be achieved through renewables microgrids for mines are evident. A diesel power plant consumers about 250 liters of fuel per MWh. A 1 MW block of solar, for example, typically produces about 2,000 MWh in a year, meaning it can displace about 500,000 liters of diesel annually.
The carbon footprint of a liter of diesel is 2.7 kg of CO2 equivalent, so the same 1 MW solar plant can result in about 1,350 tons of CO2 abatement per year. In a typical 25-year asset life, that equates to avoiding the release of more than 30,000 tons of CO2 into the atmosphere.
With expert insight from SunSHIFT, Glencore, BBA, GHD, ABB, Spirae, Sigma Energy, and ESS Energy, “Microgrids for MInes: Global Perspectives” offers informed opinions on the benefits of hybrids for mines.
