Azure International is a clean energy research and advisory firm based in Beijing. It analyzed operating data from over 5 GW of wind turbines in China, representing 20% of installed capacity from 2006-2011. The analysis found that on average, turbines operated reasonably well with a net capacity factor of 22%, though performance declined over time likely due to grid congestion issues. Individual project performance varied but provided growing evidence that turbines can operate robustly in China despite challenges around curtailment and seasonality.
