The improvement in the penetration ratios of renewables to fossil fuels, coupled with a 40% cost reduction in battery technologies since 2010 (IEA, 2017b), have further increased the attractiveness of renewable energy sources for mines. The experience from the implementation of renewable energy and storage projects, such as at DeGrussa and Weipa mines (Box 3.2), is expected to contribute to an improved understanding of renewable energy application in industrial use. Furthermore, the digital transformation of the mining sector, such as the adoption of smart grids and other internet of things-based technologies, and the use of advanced analytics and big data, have the potential to further improve mines’ energy efficiency and facilitate the integration of renewables. According to estimates, there is currently over 1 GW of on- and off-grid renewable energy capacity, installed through mining companies’ efforts, with more projects in the pipeline (Energy and Mines, 2016a).
