It is no secret that many wind energy projects around the world are underperforming their pre-construction energy yield estimates. One of the factors behind this underperformance is that many projects were built with production estimates that did not adequately account for weather variability in both space and time.

The focus of this article is to show that traditional methods for estimating the average annual energy production from a wind energy project can fall short of capturing the full risk of weather variability, and hence can lead to investment decisions based on a false sense of financial security.
