The most recent turbines added to the USWTDB became operational as recently as the second quarter of 2018, with a few from the third quarter 2018. The oldest turbines in the data set were installed prior to 1990. USWTDB releases generally lag installations by one quarter to allow for merging of the various datasets, visual verification, and quality control.
