Do batteries change everything, and by when?

This report examines the role of household batteries in the Australian residential electricity market. It forecasts that battery take-up will reach approximately 30% by 2030 and 65% by 2050, driven by declining technology costs and the emergence of aggregation models like Virtual Power Plants (VPPs). The analysis highlights that while current adoption remains in early stages with only ~2,600 batteries integrated into VPPs, the technology represents a fundamental shift for the entire electricity supply chain.
