  • Average capacity factors now around 37%, up from 25% in 1993

Improving onshore wind capacity factors

The cost of energy from onshore wind has been tumbling in recent years, in large part due to ever-improving wind turbine designs. Average capacity factors have increased from 25% in 1993 to 37% in 2017. Turbines are getting bigger too, with median capacity increasing from 2MW in 2010 to 2.4MW today. The chart shows this inexorable march, with each dot representing a wind project. Dot size indicates generating capacity and its position on the y-axis its capacity factor. Results were produced from over 2,000 runs of the BNEF Wind Capacity Factor Tool, recently re-published with 87 new turbine specifications.
