The Draft 2026 Integrated System Plan (ISP) by the Australian Energy Market Operator (AEMO) underscores the critical role of hydropower, pumped storage, grid-scale batteries, and renewable energy in Australia's future electricity system. With a focus on long-duration storage technologies to manage low wind and solar output, the plan outlines the need for 12GW of pumped storage, 32GW of batteries, and 120GW of new wind and solar by 2035. The forecasted closure of two-thirds of the remaining coal fleet by 2035 highlights the transition towards cleaner energy sources. Stakeholders have until February to provide input on the plan, offering an opportunity for businesses to stay informed and adapt to the evolving climate landscape.
