The hidden costs of low curtailment

In 2025, wind farms in the Bannaby to Yass corridor reported network curtailment rates of just 1–2%, yet merchant revenue losses reached up to 13%. The gap exists because curtailment in this corridor clusters in high-price periods driven by network outages, meaning the lost energy carries disproportionate value. It is a pattern that exposes the limits of headline curtailment metrics and carries direct implications for how developers select connection points and how offtakers price risk.
