Australia rockets to third-largest big battery market in world, as solar and wind hit "decade low"

Battery capex fell 20%, grid-scale storage is increasingly displacing gas peakers on spot pricing, and hybrid solar+battery configurations are now the primary tool for managing network congestion — a direct signal for any infrastructure or energy procurement decision.
