title: Corrected and supplemented unit data on approved wind turbines in Germany

description: This data is based on and an improvement of wind unit data in Germany of the Federal Network Agency's Core energy market data register (MaStR). The MaStR data is available for all federal states under the dl-de/by-2-0 licence.

While the MaStR is a great data source, among other things informing much of Germany's policy design, it is not without problems. For example, in many instances the date of approval of a wind unit is being overwritten by the operator or project developer. This allows the output associated with a unit to shift to a different time periods over time, leading to inconsistent and non-reproducible aggregations.

In assembling the published data here, we apply various strategies to improve on MaStR data. For instance, we retrieve the MaStR data daily using the open source software open-MaStR (Hülk et al. 2025) so we can track aforementioned overwrites. This way, we can evaluate these changes at any later point in time. For instance, our public dashboard at goal100.org uses the originally entered approval date.

Another correction is necessary concerning the specification of administrative areas: an analysis of the location data in the MaStR revealed that over 7,000 wind units (as of 27 February 2025) show conflicts between the entered administrative areas and entered geographical locations. This means that these units are located in a different municipality, district or even federal state than their geographical coordinates indicate. We use corrections published by Manske (2025), with properties on power, height, rotor diameter and geolocation, and put higher trust on this data source than the MaStR. If available, we do not overwrite these data points by our daily MaStR updates. 

Lastly, we have collected data on permit seeking projects from nine German federal states, entirely independently from the MaStR. We matched information from this collected data to units registered in the MaStR based on the coordinates and various technical specifications. Where possible, we overwrite application and approval dates that the MaStR provides with the respective dates provided by the federal states.Coordinates are in the CRS EPSG:25832 - ETRS89 / UTM zone 32N.We publish the data regularly here. If you require more frequent updates or data of units that have not been approved yet, please contact us at https://goal100.org
