Wind, Solar and Battery Projects at Record High, but Many Stuck in Funding, Supply Chain and Other Bottlenecks

Why It Matters

The expanding pipeline underpins Australia’s transition to a low‑carbon grid, but bottlenecks risk missing renewable targets and could strain system reliability as coal units retire.

Key Takeaways

• Pipeline hits 67.3 GW, 33% growth YoY
• Batteries now 49% of connection pipeline
• Funding and supply chain delays slow project progress
• Wind, solar, battery additions offset retiring 11 GW coal

Pulse Analysis

Australia’s National Electricity Market is witnessing an unprecedented surge in renewable and storage projects. The latest AEMO Connections Scorecard shows the pipeline climbing to 67.3 GW, up 33% from a year ago, with battery storage leading the charge at 49% of total capacity. This rapid growth reflects the country’s aggressive 82% renewable target for 2030 and the need to replace roughly 11 GW of coal‑generated power slated for retirement over the next decade.

However, the pipeline’s momentum is tempered by systemic bottlenecks. Project developers cite prolonged funding uncertainty, shifting ownership structures, and global supply‑chain shortages that extend the proponent implementation phase. Grid‑forming inverters, now featured in about 74% of battery projects, are essential for maintaining system strength as coal plants exit, yet their deployment adds technical complexity and cost. These delays could erode the timeline needed to meet rising electricity demand, projected to increase 28% by 2035.

Policymakers and investors must address financing gaps and streamline regulatory pathways to keep projects moving toward registration and commissioning. The Capacity Investment Scheme has provided underwriting for several projects, but only a handful have reached financial close. Accelerating capital access and stabilizing supply chains will be pivotal for Australia to capitalize on its burgeoning renewable pipeline, safeguard grid reliability, and achieve its climate ambitions.
