‘Observation-based solar and wind power capacity factors and power densities’ (Miller and Keith 2018 Environ. Res. Lett. 13 104008) contained a methodological error in how we estimated wind plant area, leading to an underestimate of wind power densities. The method and revised results were published as a Corrigendum (Miller and Keith 2019 Environ. Res. Lett. 14 079501). Given the importance of these estimates to energy policy, here in this Addendum, we expand on these corrected results, while also describing the public release of data to allow verification by third-parties. Specifically, here we: (1) illustrate our method by showing in greater detail how it works for the 2 wind power plants from figure 1 of the original study, (2) identify potential selection biases in the sampling of wind power plants used in our study, (3) provide a comparative overview of the various prior published estimates in graphical form, and, (4) conclude with a description of the data we are releasing publicly.
