Volume 12: Issue 1: Sustainable Mining

This issue of IEEE Electrification Magazine presents the theme of mine electrification and shows, in particular, that advancements in power electronics devices, battery technologies, integration of renewables, and the Internet of Things, enable effective mine electrification. Six feature articles were invited from mining-focused nations, e.g., Australia and Chile. This issue also includes a seventh feature article on using refrigeration systems for demand responses. A highlight of this article is the design and integration of a demand response system using commercially available sensors and low-computational-power devices. The history column pays tribute to Oliver Heaviside, whose contributions to the formulation of the telegrapher's equation, rebranding Maxwell equations, and operational calculus laid the foundation of electrical engineering.
