Australia distributed solar and storage: how distributed storage is powering Australia's next energy chapter

This insight examines how Australia’s world‑leading rooftop solar market is transitioning to a new era of distributed storage growth. As solar penetration surpasses 4 million rooftop systems, the grid is increasingly challenged by midday oversupply of solar generation, with implications for grid security and stability. The report explores how distributed battery storage presents a solution to reduce utility solar curtailment and improve network hosting capacity. It analyses the rapid rise of storage-to-solar attachment rates, now exceeding 100%, and assesses how the Federal Cheaper Home Batteries Program is accelerating adoption. Clients will gain essential context for understanding the evolving DER landscape in Australia and the implications for networks, policymakers, and market participants.
