Chilean mining operations are replacing diesel generators with solar-plus-storage systems. A typical 5 MW solar + 10 MWh battery system reduces diesel consumption by 80%, cuts energy costs by 40%, and achieves 6–8 year payback. Discover how mining operations in Chile can deploy large-scale battery energy storage systems (BESS) and learn about the technical specifications and control strategies for pairing photovoltaic distributed generation (PMGD) solar plants with battery storage. This will help to reduce diesel. Chile's mining sector, responsible for approximately 9% of the country's total electricity consumption, is the primary catalyst for advanced, large-scale energy storage solutions. The construction start of Chile's Dune Plus solar and battery complex signals a major shift: large-scale, multi-hour battery storage is now a core. International banks funded a 2,036 MWh solar-battery complex, proving integrated clean power is bankable for heavy industry. BHP has signed long-term agreements with Chinese energy technology company Sungrow to deploy 195 MW.
