Curtailment Revenue Loss

3 verified sources

Definition

Curtailment in Australia's NEM has reached record levels, with 6 TWh lost in 2025 YTD, equivalent to two-thirds of Tasmania's consumption. Wind farms lose dispatchable energy due to transmission limits and economic factors, directly reducing revenue if not tracked for compensation.

Key Findings

  • Financial Impact: AUD 200-500M annual revenue loss (6-8 TWh at AUD 30-60/MWh); wind-specific ~1.1-4.8% average curtailment[2][1]
  • Frequency: Daily during peak renewable output, surging 61.6% YoY in 2025
  • Root Cause: Manual tracking of curtailment events and compensation claims misses recoverable revenue from AEMO dispatch instructions

Why This Matters

The Pitch: Wind power generators in Australia waste AUD 100M+ annually on untracked curtailment. Automation of curtailment tracking and compensation claims recovers this revenue.
